Fire dampers for ventilation systems are special devices that are designed to prevent combustion products from entering the ventilation system and cut it off from the source of fire. These are made mainly from materials that can withstand exposure to significant temperatures for a long time.

Classification by design features

The main regulatory document that regulates the areas of their use in fire ventilation systems is SNiP 41-01-2003. According to this regulatory document, the following types of devices are produced:

Valve opening is normal. Mounted on exchange air ducts of conventional ventilation systems, in air exchange and air conditioning systems, as well as in networks air heating to prevent toxic combustion products from entering the system. And for supply and exhaust air ducts for premises equipped with automatic fire extinguishing systems, with gas or powder filling. Such devices are activated to close to form a sealed space in the room, filled with fire extinguishing agent to increase the effectiveness of fire extinguishing. They operate automatically upon command from the fire extinguishing system.

Operation of a fire-rated wall normally open damper using the example of the PSUM 90 MANDIK model:

A normally closed valve is installed in specialized ventilation systems to remove smoke and waste fire extinguishing gas from the room. They open manually or on command from fire dampers, after the source of fire has been completely eliminated.

Operation of a normally closed fire damper using the example of the MANDIK PKTMIII 60 model:

Double-acting devices are used in air ducts for similar purposes, which are used both for ventilation of the building and for cleaning the building from fire combustion products. They can be controlled automatically from the fire extinguishing installation or have their own control device if the room is equipped with autonomous gas fire extinguishing modules.
Smoke dampers for smoke exhaust systems are smoke removal devices that are shut-off and adjustable equipment.

The devices are installed at the intersection of smoke exhaust system pipelines and interfloor ceilings, walls and partitions. Typically, such devices are equipped with two types of controls:
- The electromagnet is an economical one, which is in a normally closed standby state. When a fire is detected, a pulse is sent to the electromagnet, which removes the blockage. The lid will rise due to the mechanical force of the spring. The damper returns to the reverse - security state - manually.
- The electric drive is in the closed standby state and is de-energized. When the need arises, electrical power is supplied to the damper, which is opened by an electric motor. The device returns to its original position automatically upon command from the fire extinguishing system or control cabinet.
Explosion-proof valves come in two types. Normally open and closed. Their use and installation in air ducts for various purposes is regulated by regulatory documents SNiP 41-01-2008 and SNiP 21-01-97. Such devices are equipped with industrial exhaust ventilation systems in hazardous and aggressive industries. Their strength and performance indicators are significantly superior to conventional devices. The operating temperature range is -30°C to +40°C.

For long-term operation of devices, you must adhere to the following rules in accordance with GOST 15150-69:

Maintain temperature conditions;

Protect the main control units and the device housing from negative impact atmospheric moisture and direct ingress of water;

Avoid condensation or other types of moisture entering the device damper;

Do not use conventional (unprotected) devices in air supply or removal systems that have a dual purpose and are used for suction of aggressive substances from the production site. Or in an environment of aggressive gaseous substances, vapors of acids and alkalis, the maximum concentrations of which reduce the corrosion of the body.

BUG 1

Fire damper KLOP 1 blocks the entry of smoke and its spread throughout ventilation ducts, used in air heating and central air conditioning systems. It can be used both in public buildings or industrial buildings for various purposes, and for ventilation systems installed in a private home.

A channel-type device is produced with a control system equipped with two flanges and a power electric drive located outside the air channel. The fire resistance limit depends on the materials from which the body and damper of the device are made. The most popular models are IE60 and IE90, capable of withstanding 60 and 90 minutes of direct exposure to fire.

Various modifications of the KLOP 1 product can be equipped with:

Automatic thermal blocker, triggered at 72°C;
Power unit on coils activated by a temperature sensor at 72°C;
Mechanical lock with a spring drive, activated by a thermal sensor of 72°C or 141°C, complete with a microswitch between modes.

KPU 1M

Fire damper KPU 1M - in standby mode the device is energized in a normally open state. It is equipped with a built-in return spring, pre-charged into working condition, and an activation electric drive (BELMO). When the device is de-energized, the spring is activated, setting the damper to the closed position.

The device is triggered in the following cases:

When there is a power failure;
Upon receipt of a command from an automatic fire extinguishing system or a separate valve control module;
When the threshold critical temperature in the air duct reaches 72°C;
In the extended configuration, it is possible to install an additional thermostat to determine the temperature in the room - it will trigger when it reaches 72°C.

KPS

The KPS fire damper can be used in combined and combined dual-purpose air ducts, since it works normally both in open and closed states. And it can be used as a smoke control or fire retardant device.

Various models can be equipped with electromechanical locks of both domestic and foreign production (Siemens). And also be equipped with an electromagnetic or spring lock with or without additional activation thermal sensors.

The use of fire dampers will increase. In addition, choosing a reliable model can make the smoke removal system more reliable, eliminating delays in operation.

Description of actuators for fire dampers

Electromechanical spring return actuators designed to control dampers that are installed in ventilation and air conditioning systems.

The control signal for operation with an electromechanical servo drive is the removal of voltage from the drive, resulting in return spring moves the air damper from its original position to the working (protective) position. When voltage is applied to the drive, the electric motor moves the damper to its original position and holds it in this position, consuming little power.

Drives fire dampers

a manual control mechanism, thanks to which you can return the damper to
initial position when the power source is turned off;
two built-in switches signaling the operating (protective) position of the damper (up to 5°) and the initial position of the damper (90°-95°);
a spring (spring return), with the help of which the position of the air damper changes;
thermal release device (models with temperature sensor -T), triggered at a given temperature (only for normally open valves).

Fire actuators Nanotek fire dampers

Nanotek Spring Return Servos are in great demand among Russian consumers and are similar in their labeling to Belimo electric drives.

Like Belimo, fire safety Nanotek divided into two lines for small and medium valves. Nanotek BLF are installed on dampers up to 1 m², and Nanotek BF it is already possible to connect to a damper up to 1.5 m².

It is worth noting that the Nanotek BLF 24/230 B 3 MB models are not complete analogues of the Belimo BLF, because torque 3Nm, versus 6Nm for Belimo. Otherwise the characteristics are similar. So closer to Belimo BFN230 (4Nm motor and 3Nm spring) than BLF230 (6Nm/4Nm). And it’s also worth paying attention to the Nanotek BLF 24/230 B MB models - these drives are 5Nm.

Nanotek BF– these are 10Nm drives, while the Belimo BF has 18Nm motor drives. Closer to the BF will be the Dastech FR models at 15 Nm. This is all you need to keep in mind when choosing analogue of Belimo to make the right choice.

Types and range of electric actuators for valves

Each type of electric drive is focused on performing a certain type of task. When purchasing equipment, you must take into account its purpose, characteristics and functionality. If you are not knowledgeable enough about this topic, it is better to seek help from professionals.

Before as buy an electric valve, it is necessary to take into account the following features:

Availability of a power supply that will allow the equipment to operate in different ranges of the electrical network;
Signal type: analog, three-position;
Type of shell;
Type of material used in production;
The presence of an automatic locking system that can protect equipment from overload;

Electric actuators for fire dampers with return spring - actuators with return spring are universal equipment suitable for almost all ventilation systems. The operation of the equipment occurs due to the accumulation of mechanical energy during the rotation of the damper to the operating position. Energy release occurs during emergency closure.
Electric drives for fire dampers are reversible - they are mainly used in supply and exhaust smoke ventilation systems. This happens due to the peculiarities of the equipment. It consists in the impossibility of moving the valve flap from its initial state to the operating state for any possible options power outages. An adjustable electric drive of this type operates in a stressful intermittent mode, which is characterized by frequent starts and braking.

Important: The electric drive can also be controlled remotely. For this, a positioner with an analog signal from 0-10V is used.

Principles for choosing an electric drive

If you want to select an electric drive yourself, you should consider several main aspects of these devices.

Drive mount type. The connection can be carried out different ways. The most common types of fastening are latches, nuts and cups. So, when choosing a valve, you must take into account the type of connection to the electric drive.
Type of valve action. The valves also differ in their operating principle. They are geared and thermoelectric. The operation of gear drives occurs thanks to a gear transmission. This type of device allows energy to be transferred from the motor itself directly to the valve, which powers it. The thermoelectric type of drives operates on an electric spiral. The coil itself heats up and increases the pressure. As it rises, the valve stem begins its work.
Stock size. This operating parameter can vary from 5 to 50 mm. It is important to know that for correct operation it is necessary to select a drive whose stroke value will exceed the rod value.
Performance. This indicator seems unimportant, but it is worth paying attention to it. So, there are fast and slow electric drives. Thus, it is preferable to install a fast type of device on inertial systems ( average speed reactions – 3 seconds).
Voltage. It is especially worth considering the voltage level, which can vary from 24 to the usual 220 V.
Working effort. It is also worth taking into account and focusing on this parameter almost in the first place. So, it can vary from 50 to 5000 N.
Protection. An important parameter is the presence of additional devices. The most important of them are protective. Typically, a high-quality device is equipped with a spring, which ensures quick closing without electricity. The device may also have an additional air damper. Its function is to protect the heater from low temperatures.

Taking these parameters into account when choosing an electric drive, you can have complete confidence in the correct operation of the device.
