Abstract
The utility model relates to a one-way valve for a fire extinguishing agent storage container. The front end of the one-way valve is connected with the fire extinguishing agent storage container; the back end of the one-way valve is connected with a fire extinguishing agent nozzle; the one-way valve comprises a valve body, a valve core and a joint, wherein a stepped through hole is in the valve body; the valve core is arranged on the back part of the through hole; a drive gas pipe interface and a fire extinguishing agent filling port are formed in the front waist of the valve body; a taper hole is formed on the middle part of the valve body and corresponds to a taper at the front end of the valve core; a blind hole is formed at the back end of the valve core and is communicated with a hole on the side wall of the valve core; and a thrust spring is arranged in the blind hole of the valve core. The one-way valve has the advantages that: in an automatic gas fire extinguishing system, the problems of sealing and unsealing reliability of the fire extinguishing agent storage container are solved; and a container valve and the one-way valve are combined into a whole, so that the system is simplified, operation processes are omitted, production cost is reduced, and guarantee in the aspect of safe use is improved.
Description
Technical field
The utility model relates to a kind of extinguishing device, especially the valve of the foamite storage container in the fire-smothering gear.
Background technology
In the automatic gas fire extinguishing system, extinguishing agent storage vessel all need be installed container value.During system works, extinguishing chemical discharges through container value, flows backwards for preventing extinguishing chemical, has set up check valve again in the container value back.The invention of the unidirectional container value of the utility model is need use the system that drives gas cylinder supercharging ability release fire suppression agent to extinguishing agent storage vessel.
Unidirectional container value is that combination container value and check valve are one, and as the critical component in the system, its sealing property, unlatching reliability all are directly connected to the security reliability that whole automatic fire extinguishing system moves.
The utility model content
In order further to improve in the automatic gas fire extinguishing system, solve sealing, the unlatching integrity problem of foamite storage container, the utility model provides a kind of foamite storage container check valve.
The content of the utility model is such: the foamite storage container check valve, and front end and foamite container join, and rear end and extinguishing chemical spout join, and it comprises valve body 1 and spool 4, joint 7; In the described valve body 1 is step through-hole, and spool 4 is arranged on the through hole latter half, is provided with driving air pipe interface 8 valve body 1 Attacking Midfielder and fills mouth 2 with extinguishing chemical; Valve body 1 middle part is a taper hole; Corresponding with spool 4 front end cones, spool 4 rear ends have blind hole, and communicate with hole on spool 4 sidewalls; In spool 4 blind holes thrust spring 6 is arranged.Described extinguishing chemical fills mouth 2 and is provided with plug; Spool 4 cones are provided with O RunddichtringO 3; Thrust spring 6 head and the tail are caged valve core and joint respectively; Joint 7 joins through internal thread and valve body tail end external screw thread, and getting along at valve body tail end end face and joint is provided with sealing ring 5.
The advantage of the utility model is:
1, in the automatic gas fire extinguishing system, solve sealing, the unlatching integrity problem of foamite storage container, and be combined as a whole container value and check valve, aspect safe handling, improved assurance.
2, its simple in structure, handling ease of the utility model, low cost of manufacture; The valve seal designed reliability is high, under driving gas driving situation, and accurate, the flexible Open valve of ability, reliability is high;
3, the design of the utility model is collection container value and check valve one, simplifies the structure, and has practiced thrift operational sequence, greatly reduces production cost.
Description of drawings
Fig. 1 is the structure chart of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
The utility model work is following:
Join with the driving tracheae at driving air pipe interface place; When driving gas gets into valve inner, promote spool, gas pressure compression thrust spring; Open the valve of the utility model; Driving gas gets in the container through the foamite container bottleneck, the valve of extinguishing chemical pressurized through bottleneck, the utility model in the container, flows to pipeline, discharges fire extinguishing through shower nozzle at last.When extinguishing chemical refluxed to unidirectional container value through pipeline, spool received thrust spring tension force, and with valve seal, liquid can not pass through.
Combined accompanying drawing that the specific embodiment of the utility model has been carried out exemplary description above, obviously the utility model is not limited thereto, and the various remodeling that in the utility model scope, carry out all do not exceed the protection domain of the utility model.
