Abstract
The utility model relates to a fire-froof valve, which mainly solves the defects of the automatic close of the pipelines with combustible gas and combustible liquid under the high temperature. The utility model is characterized in that a temperature sensing head is connected with a pressure chamber through the pipelines; the temperature sensing head is a fusible plug; the inner part of the pressure chamber is provided with a piston; the piston is connected with valves through connecting rods; the upper part of the valves is provided with guiding rods; the valve cover is provided with guiding tubes; the guiding rods can move upwards and downwards inside the guiding tubes; the space between the valve and the valve cover is provided with a spring; the valve, the guiding tubes, and the guiding rods are installed inside the valve body, the valve body is provided with an outlet and an inlet. The utility model is suitable for the electricity controlling and manual opening and closing of the conveying pipelines with combustible gas and combustible liquid and has the automatic fire-proof function.
Description
The utility model relates to a kind of mechanical type fire resisting damper.
Carry the design that has the fire resisting damper of automatic fire prevention function in combustible gas, the liquid line in the prior art, use seldom.The fire safety problem of this type of pipeline is taken into account by electric control valve mostly, in case the fire alarm dangerous situation occurs, the valve of in time closing in the transfer pipeline just seems very critical, especially as earthquake, blast, war etc. very under the environment.
The purpose of this utility model provides a kind of mechanical type temperature-sensitive fire resisting damper.Solve the fire safety problem of carrying flammable gas, liquid pipeline.
The utility model is made up of temperature-sensitive head, balancing gate pit, valve member and valve body.It is characterized in that: temperature-sensitive head links to each other with the balancing gate pit by pipeline, temperature-sensitive head is one to clog the fusible plug of pipeline, one piston is arranged in the balancing gate pit, piston links to each other with valve through connecting rod, and guide rod is equipped with on valve top, has conduit, guide rod on the valve gap and can move up and down in conduit, one spring is arranged between valve and valve gap, there is a valve port valve below, and with guide rod, catheter cartridge in valve body, have an outlet and an import on the valve body.
This fire resisting damper is filled with compressed air in the balancing gate pit, and piston is under compressed-air actuated promotion, and drivening rod, valve rise fire resisting damper place opening, spring place compressive state.Because temperature-sensitive head is a fusible plug, when monitoring temperature surpasses setting value, fusible plug fusing or pipeline break under external force, just the compressed air of releasing, balancing gate pit's internal pressure reduces, and valve moves down together with piston under spring promotes, and valve is blocked valve port, automatically blind off a line, reach the fire prevention purpose.
The utility model is simple in structure, and reliable in action can singly only be used, and an also denumerable interlock can be automatically controlled, can manually open and close, and closes automatically in the time of in case of fire.If close oil transportation, air pipes such as airport, harbour.Especially under adverse circumstances such as earthquake, blast, war, more can bring into play its effect.
Below in conjunction with accompanying drawing, the structural representation of the utility model fire resisting damper is elaborated.
Accompanying drawing is the structural representation of the utility model fire resisting damper.
In the structural representation shown in Figure 1,12 expression temperature-sensitive heads, temperature-sensitive head is one to clog the fusible plug of the mouth of pipe, temperature-sensitive head links to each other with balancing gate pit 6 by pipeline, one piston 10 is arranged in the balancing gate pit, piston links to each other with valve 4 by connecting rod 9, and guide rod 3 is equipped with in the valve top, and conduit 2 is arranged on the valve gap 1, guide rod can move up and down in conduit, one spring 7 is arranged between valve and valve gap, and valve, conduit, guide rod, spring are contained in the valve body 8, and an import 5 and an outlet 11 are arranged on the valve body.
