What are the manufacturers of civil air defense doors?

Civil air defense doors, as the name implies, are doors to prevent people from accidents, which are basically seen in crowded places, especially in some large supermarkets. The doors at the safety exits are basically civil air defense doors. At the same time, there are many classifications of civil air defense doors, and the functions of different classifications are also somewhat different. So how to choose the right air defense door or how to buy a good one? Next, Bian Xiao will introduce several manufacturers of air defense doors to you.

Classification and characteristics

1, ordinary single and double fans protect sealed doors and sealed doors.

This kind of door is the earliest and has been widely used. It is characterized by simple structure, reliable operation and convenient maintenance, and is suitable for the entrances and exits of various civil air defense projects. However, because it has a threshold, it has been rarely used in projects where people and cars come and go frequently. For example, underground shopping malls that combine peacetime and wartime have been replaced by life threshold doors or landing doors with the same size and load level.

2, the threshold of life, sealed door and sealed door double protection.

This kind of door is characterized by no threshold at ordinary times, flat ground and convenient passage for people and vehicles. In the face of war, the threshold can be quickly installed to meet the requirements of protection and sealing functions, and the conversion of peacetime and wartime functions can be quickly realized.

This kind of door is suitable for the entrance and exit of civil air defense projects such as underground shopping malls, hospitals, warehouses and underground parking garages.

3. Rubber hose type explosion-proof wave valve

Rubber hose explosion-proof wave valve is a kind of valve that can be closed quickly under the overpressure of shock wave. After the rubber tube is deformed, most of the shock waves are blocked out of the project, and a small part of the shock waves enter the diffusion chamber at the head of the project for further expansion and diffusion? Finally, it is weakened to the allowable safety pressure. When the overpressure design value of air shock wave acting on the rubber tube explosion-proof wave valve is not greater than 0.3MPa, the diffusion chamber can be cancelled in the wave attenuation system and the rubber tube explosion-proof wave valve can be directly used; Rubber hose explosion-proof wave valve is only applicable to the ventilation system of this project, not to the smoke outlet.

4. Suspended explosion-proof wave (shielding) valve

The invention is simple in structure, convenient to use and maintain, and can be used for the air inlet, air outlet or smoke outlet of the project. The floating explosion-proof wave shielding valve is developed on the basis of the ordinary floating explosion-proof wave valve, and its anti-electromagnetic pulse ability is secondary.

5. Floor-mounted double fans protect sealed doors and sealed doors.

This kind of door is characterized by no threshold on the ground at ordinary times, which is convenient for people or vehicles to pass through; In wartime, the door leaf will turn vertically, land and translate to meet the requirements of protection and sealing, and there is a small door that is convenient for people to enter and exit temporarily, which makes the transition from peacetime to wartime quick. The new hall door has improved the lifting mechanism and is more convenient to operate.

6. The connecting port is stressed in two directions, and the sealed door is protected by double doors.

This kind of door is set on the protective airtight partition wall of the communication port of two adjacent protective units, and its characteristics are flat ground, no threshold, two-way stress, two-way sealing and fast transition from peacetime to wartime.

7. The sealed door is protected by two open doors on the ramp.

This kind of door is suitable for the ramp terminal of the entrance and exit of civil air defense projects. The gate opens to the interior of the project, and there is no threshold protruding from the ground at ordinary times, so the peacetime and wartime conversion is fast.

8, protective fire seal door, fire seal door.

The remarkable feature of this kind of door is its strong disaster prevention ability. There are fireproof fillers and sealing measures in the door leaf, so it can prevent fire, smoke and water. Like other sealed doors, it can also protect against shock waves, biological warfare agents and chemical warfare agents in wartime, which fully meets the requirements of civil air defense projects in peacetime and wartime.

This kind of door can be installed on the partition wall between the fire exit and two adjacent protection units.

9. Electric control door

Electronically controlled doors can be divided into four categories: electronically controlled sealed doors, electronically controlled sealed doors, electronically controlled closed screen doors and electronically controlled protected doors, among which the electromagnetic pulse protection capability of electronically controlled closed screen doors is level 3. This kind of electric control door is portable and flexible in manual operation. It is a dual-purpose electric control door, that is, the switch door and the switch lock share a power device. It has three control modes: local control, remote control and intelligent control (access control system), and can be equipped with safety monitoring and electromagnetic lock devices according to engineering needs.

10, plug-in board

(1), the communication port is protected and closed.

The closed plug board for communication port protection is characterized by assembly, light weight, modular size and easy installation. It is suitable for quickly plugging the communication opening of the partition wall of two protection units in the face of war, and is not suitable for plugging the hole of the external wall of civil air defense projects.

The tuyere protection sealing is suitable for quickly sealing the air duct through-wall hole on the partition wall between two protection units in wartime, but not for sealing the external through-wall hole.

(2) Airtight sealing plate for airport fence protection

This kind of sealing plate can be used to seal the orifice used in peacetime, but not in wartime. Its characteristic is that it is not necessary to install the sealing plate at ordinary times (but it should be processed and placed in the designated position nearby), and it can be installed quickly according to the preset conversion time limit in wartime to meet the protection and sealing requirements. According to the different installation positions, it can be divided into two categories: two-way stress protection sealing plate for protecting the vent or communication port of the unit and sealing plate for adjacent walls.

1 1, protect the closed screen door and the closed screen door.

This kind of door has the composite functions of protection, sealing and shielding or sealing and shielding, and the protection level is level 2.

Several manufacturers of civil air defense doors are introduced here. Generally speaking, these companies have been established for a long time, and their products have always attracted people's attention. I believe the quality is comparable to or even better than that of other manufacturers. From the price point of view, the prices of these civil air defense doors are not very comparable, probably because they are domestic brands, so the prices are more acceptable.
