The fire-proof valve comprises cover plates, a valve plate, a valve body, a pneumatic assembly and a temperature sensor, wherein the two cover plates are connected with the valve body through fasteners, the temperature sensor is installed on a circular straight pipe section of the cover plates, the valve plate is arranged inside the valve body, the fixed end of the pneumatic assembly is connected with the valve body, the telescopic end of the pneumatic assembly is connected with the valve plate, and the pneumatic assembly controls the valve plate to act to control the fire-proof valve to be opened or closed. The utility model has the advantages that: the fire damper is of a drift diameter and resistance-free structure, and is flexible to operate and quick in response.
Description
Technical Field
The utility model relates to a fire prevention valve, concretely relates to non-resistance fire prevention valve.
Background
The fire-proof valve is normally opened, and is closed at 70 ℃ or 280 ℃, and is generally installed at the position where an air pipe passes through a fire wall and a structural deformation joint to play a role in controlling fire, and can be used for setting an output electric signal, and when the temperature exceeds 70 ℃ or 280 ℃, the valve is closed, and the linkage air supply (compensation) fan is closed.
The fire-proof valves are arranged at the positions where the main air supply and return ducts pass through the partition walls and the floor slabs of the machine room, and the fire-proof valves are arranged at the positions of the wall-penetrating positions of the air ducts of different fire-proof subareas and the like. The function of the fire damper is to prevent fire from spreading to other subareas and systems when fire occurs in local pipeline or space in the air return system.
When the fire damper is installed in a pneumatic material conveying system, due to the structural characteristics of the fire damper, filamentous or viscous materials can be easily wound on a valve plate of the fire damper, so that the action failure of the fire damper or the blockage of a pipeline is caused.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a non-resistance fire-proof valve, which adopts the drift diameter and non-resistance form, is powered by a pneumatic component and can respond quickly.
The utility model discloses a realize through following technical scheme: a non-resistance fire prevention valve which is characterized in that: the fire-proof valve comprises cover plates, a valve plate, a valve body, a pneumatic assembly and a temperature sensor, wherein the two cover plates are connected with the valve body through fasteners, the temperature sensor is installed on a circular straight pipe section of the cover plates, the valve plate is arranged inside the valve body, the fixed end of the pneumatic assembly is connected with the valve body, the telescopic end of the pneumatic assembly is connected with the valve plate, and the pneumatic assembly controls the valve plate to act to control the fire-proof valve to be opened or closed.
The valve plate on be equipped with the trompil, the diameter of trompil is the same with the diameter of circle straight tube section, when pneumatic assembly control valve plate opened, the trompil of valve plate and the coincidence of the circle straight tube section position of apron, when pneumatic assembly control valve plate closed, the trompil of valve plate and the circle straight tube section position of apron stagger completely.
The utility model has the advantages that: the fire damper is of a drift diameter and resistance-free structure, and is flexible to operate and quick in response.

In the figure: 1. a cover plate; 2. a valve plate; 3. a valve body; 4. a pneumatic assembly; 5. a temperature sensor; 6. a circular straight pipe section; 7. and (6) opening holes.
Detailed Description
A non-resistance fire damper as shown in fig. 1 to 3, characterized in that: including apron 1, valve plate 2, valve body 3, pneumatic component 4 and temperature sensor 5, two apron 1 are connected with valve body 3 through the fastener, and temperature sensor 5 installs on the straight section of pipe 6 of circle of apron 1, and valve plate 2 is established in the inside of valve body 3, and pneumatic component 4's stiff end links together with valve body 3, and pneumatic component 4's flexible end links together with valve plate 2, and pneumatic component 4 controls opening or closing of 2 action control fire prevention valves of valve plate.
The valve plate 2 on be equipped with trompil 7, the diameter of trompil 7 is the same with the diameter of circle straight tube section 6, when pneumatic component 4 control valve plate 2 opened, the trompil 7 of valve plate 2 and the 6 position coincidence in circle straight tube section of apron 1, when pneumatic component 4 control valve plate 2 closed, the trompil 7 of valve plate 2 and the 6 position staggers completely of circle straight tube section of apron 1.
When the temperature sensor 5 detects that the temperature reaches a set value, the pneumatic assembly 4 controls the valve plate 2 to act, so that the fire damper is closed.
The device is mainly characterized in that the fire damper is of a drift diameter and resistance-free structure, and is flexible to operate and quick in response.
