Abstract
The utility model relates to a gas control pipeline one-way valve. The gas control pipeline one-way valve provided by the utility model is formed by coaxially arranging a valve body, a valve core and a joint, wherein the valve body is a tubular body, a step hole is formed inside the valve body; an internal thread is formed at the back end of the valve body; a conical hole is formed at the front end of the valve body; the valve core and a spring adjusting nut are arranged inside the middle end of the valve body; the front end of the valve core is conical, and is matched with the conical hole at the front end of the valve body; the back end of the conical body is provided with a shaft body; the shaft body is sleeved with a thrust spring; and the back end of the valve body is connected with the joint. The gas control pipeline one-way valve provided by the utility model has the advantages of simple structure, easiness for processing, low manufacturing cost and high reliability of a hermetic design; under the thrusting action of gas pressure, the valve can be opened accurately and reliably, and the reliability is high; and the inner nut is adjustable, so that the magnitude of the opening pressure can be adjusted as required, the gas control pipeline one-way valve can be general in various systems, and the practicability is enhanced.
Description
Technical field
The utility model relates to a kind of fire-fighting equipment, especially is used for the valve of control gaseous in the fire-smothering gear.
Background technique
In the combined distribution system of extinction using gas, we discharge propellant through pneumatic pipeline and drive extinguishing agent storage vessel valve, release fire suppression agent.In pneumatic pipeline, be provided with the one-way valve of a special use, flow in order to the controlling and driving gas unidirectional, select to drive corresponding extinguishing agent storage facility through the flow direction of control gaseous.
Extinction using gas is applied to the ship of war and aircraft the earliest in China, and development has also obtained broad development at civil area so far.Along with the development of extinction using gas technology, the gas unidirectional valve is as the critical component of pneumatic pipeline, and the accuracy of its sealability, cracking pressure, the reliability of unlatching are directly connected to the safety reliability of whole system.
The model utility content
For the sealability of further improving gas pilot line one-way valve, the accuracy of cracking pressure, the reliability of unlatching, the utility model provides a kind of novel gas pilot line one-way valve.
The gas pilot line one-way valve of the utility model is by valve body 1, spool 2 and joint 6 coaxial settings, and valve body 1 is a tubular body, and inside is step hole, and the rear end is provided with internal thread, and its front end is a taper hole, and the middle-end set inside has spool 2, spring adjusting nut 5; Described spool 2 front ends are cone, cooperate with the taper hole of valve body 1 front end, and the cone rear end is an axis body, is with thrust spring 4 on the axis body; Valve body 1 rear end is connected with joint 6.
There is through hole at spring adjusting nut 5 centers, and spool 2 rear end axis bodies penetrate wherein, and 4 of thrust springs are pressed in spring adjusting nut 5 surfaces.
Described valve core cone is provided with valve core seal ring 3.Described joint 6 is the step axle, and an end also is provided with O RunddichtringO 7 through being threaded into valve body 1 rear end at the step of joint 6 and the end face contacting point of valve body 1 rear end.Described valve body front end is provided with outside thread.
Its simple in structure, easy processing of gas pilot line one-way valve of the utility model, its Seal Design reliability of low cost of manufacture is high; Under the promotion of gas pressure, Open valve accurately and reliably, reliability is high; The inner nut can regulate can be debugged the size of cracking pressure as required, can be general in multiple systems, improved practicability.
Description of drawings
Fig. 1 is the structural drawing of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
In the use of the utility model, its front end (being the inflow end of gas) drives gas cylinder with fire protection equipment and is connected; Its rear end (being holding by flowing into of gas) is connected with the pilot valve structure of foamite container, and pilot valve is with opening foamite container.
After fire protection equipment drives the gas cylinder unlatching; Propellant to gas pilot line one-way valve, promotes spool 2 through the pipeline positive flow then, and thrust spring 4 receives force compresses; In the valve body 1 inner gas passageway that forms; Gas stream is crossed valve body and joint then, flows to the pilot valve of foamite container, opens the fire extinguishing of foamite container and release fire suppression agent.
When gas reverse flow during to the utility model, thrust spring 4 is recovered by tension force, and promotes spool 2, and it is cut off the gas passageway, and gas can not pass through, and can not arrive next valve, can not drive next valve open.
Combined accompanying drawing that the 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.
