Abstract
The invention provides a leakage protection valve for a natural gas pipeline, which comprises a housing, a valve and a valve base, wherein an external thread is formed at one end of the housing, the valve base is connected with the other end of the housing, a vent hole is formed in the center of the valve base, the valve on which a valve spring is mounted in a sleeving manner is arranged in and fixedly connected with the vent hole of the valve base, and a seal ring is arranged on the valve. The leakage protection valve is installed in the natural gas pipeline to automatically cut off the outgoing gas in case of breakage or damage of the pipeline, so as to prevent high-pressure gas leakage, improve the operating safety and reduce accidents and losses. The leakage protection valve has a simple and smart structure, is easy to fabricate, and has no special requirement for materials.
Description
Technical field
The present invention relates to a kind of gas pipeline and reveal Protective valve.
Background technique
Popularize rapidly along with what rock gas used, rock gas has become one of main green clean energy resource of China.But, if cause pressure duct to break and joint pitches, just there are a large amount of high-pressure natural gas gases sprays to let out, in the extremely short time, will assemble a large amount of inflammable gass so, in case contact burning things which may cause a fire disaster, must lead to major disaster, consequence is hardly imaginable.When pipe breakage, can close air outlet two automatically high-pressure natural gas is leaked if can guarantee rock gas, just can alleviate the disaster degree of accident.
In view of this, be necessary gas pipeline in the existing technology is improved, to address the above problem.
Summary of the invention
The object of the present invention is to provide a kind of rock gas competent system, can be good at adopting the direct transport natural gas of pipeline, the convenient detection.
For realizing the foregoing invention purpose; The invention provides a kind of gas pipeline and reveal Protective valve, comprise housing, valve and valve seat, an end of said housing is provided with outside thread; Said valve seat is connected with the said housing the other end; Said valve seat central authorities are provided with vent, and the valve that is set with valve spring is arranged in the vent of said valve seat and is connected, and said valve is provided with seal ring.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is through the anti-leak protection valve is installed in gas pipeline, when pipe breakage or damage; Can close giving vent to anger automatically, avoid high pressure gas leakage, improve safety in utilization thereby reach; Reduce causality loss, this apparatus structure is simple, and is small and exquisite; And processing technology is simple, and material is not had specific (special) requirements.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present invention;
Among the figure: 1 housing, 2 valves, 3 seal rings, 4 valve springs, 5 valve seats, 6 nuts.
Embodiment
Below in conjunction with each mode of execution shown in the drawings the present invention is elaborated; But should be noted that; These mode of executions are not limitation of the present invention; The function that those of ordinary skills do according to these mode of executions, method, or structural equivalent transformation or substitute all belong within protection scope of the present invention.
Please join shown in Figure 1; The invention provides a kind of gas pipeline and reveal Protective valve, comprise housing 1, valve 2 and valve seat 5, an end of said housing 1 is provided with outside thread; Said valve seat 5 is connected with said housing 1 the other end; Said valve seat 5 central authorities are provided with vent, and the valve 2 that is set with valve spring 4 is arranged in the vent of said valve seat 5 and is connected, and said valve 2 is provided with seal ring 3.
The outside thread of housing 1 is connected with pipeline, and the gap between valve 2 and the valve seat 5 is accurately set up by nut 6, and the rigidity of valve spring 4 will confirm according to the size of bleed pressure, and the closing to be pressed onto on the valve seat 5 by valve sealing ring 3 of valve realized.
The present invention, can close giving vent to anger when pipe breakage or damage through the anti-leak protection valve is installed in gas pipeline automatically; Avoid high pressure gas leakage thereby reach, improve safety in utilization, reduce causality loss; This apparatus structure is simple; Small and exquisite, and processing technology is simple, and material is not had specific (special) requirements.
The listed a series of detailed description of preceding text only is specifying to feasibility mode of execution of the present invention; They are not in order to restriction protection scope of the present invention, allly do not break away from equivalent mode of execution or the change that skill of the present invention spirit done and all should be included within protection scope of the present invention.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned example embodiment, and under the situation that does not deviate from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore; No matter from which point; All should regard embodiment as exemplary; And be nonrestrictive, scope of the present invention is limited accompanying claims rather than above-mentioned explanation, therefore is intended to the implication of the equivalents that drops on claim and all changes in the scope are included in the present invention.Should any reference character in the claim be regarded as limit related claim.
In addition; Describing according to mode of execution though should be appreciated that this specification, is not that each mode of execution only comprises an independently technological scheme; This narrating mode of specification only is for clarity sake; Those skilled in the art should make specification as a whole, and the technological scheme among each embodiment also can form other mode of executions that it will be appreciated by those skilled in the art that through appropriate combination.
