Abstract
The invention discloses to an automatic hydraulic natural gas safety valve and relates to a hydraulically-controlled automatic safety valve. The valve consists of a valve body and a hydraulic cylinder and is characterized in that the valve body is provided with a natural gas inlet and a natural gas outlet, and a valve wall opposite to the natural gas inlet is provided with a through hole. The hydraulic cylinder is mounted in a support which is mounted in the valve body, a piston rod of the hydraulic cylinder penetrates through the through hole of the valve body to enter the valve body, and a plug is mounted in the front of the piston rod. The hydraulic cylinder is connected with an external hydraulic system through a pipeline, and the inner wall of the valve body is coated with an amine curing agent coating. The automatic hydraulic natural gas safety valve has the advantages of novel structure, simplicity and convenience in processing, convenience in use, safety, reliability and the like and is a novel automatic hydraulic natural gas safety valve integrating economy and practicality.
Description
Technical field
Hydraulic pressure rock gas automatic blow off valve of the present invention, relates to a kind of hydraulic control automatic safe valve.
Background technique
The situation that pipeline is revealed now occurs often, and the leakage of rock gas all can bring many inconvenience to daily life and production.When leaking after generation, first thing that will do will be blocked pipeline exactly, do not allow the rock gas in pipeline continue to reveal.The device that we will a leak stopping in time like this, for existing problem in above-mentioned prior art, a kind of novel hydraulic pressure rock gas automatic blow off valve of research and design, is very necessary thereby overcome existing problem in prior art.
Summary of the invention
In view of existing problem in above-mentioned prior art, the object of the invention is a kind of novel hydraulic pressure rock gas automatic blow off valve of research and design.In occurring to leak at pipeline, the pipeline of leakage is blocked in time, no longer made the rock gas in pipeline continue to reveal.
Technical solution of the present invention is achieved in that
Hydraulic pressure rock gas automatic blow off valve of the present invention, is made up of valve body and oil hydraulic cylinder; It is characterized in that being processed with Imported gas and gas outlet on valve body, on the valve wall of the opposite of Imported gas, be processed with through hole; Support is loaded on valve body, and oil hydraulic cylinder is loaded in support, and the piston rod of oil hydraulic cylinder enters in valve body through the through hole on valve body, and in the front portion of piston rod, plug is housed; Oil hydraulic cylinder is connected with external hydraulic system by pipeline; Valve interior wall scribbles amine curing agent coating.
On piston rod of the present invention, be processed with boss, boss is used in conjunction with the spring detent being loaded on rack side wall.
On through hole of the present invention, seal ring is housed.
Using process of the present invention is:
In the time that external equipment receives leakage signal, primer fluid pressing system, to oil hydraulic cylinder fuel feeding, promotes piston rod and stretches out, and plug is pressed in Imported gas; Protracting of piston rod drives the boss on piston rod to protract, and spring detent slips over boss, and piston rod is pinned.After leakage repairs, hydraulic system pressure release is opened spring detent again, piston rod retraction Open valve.
Advantage of the present invention is apparent, is mainly manifested in:
1, the present invention can seal pipeline the very first time in the time leaking generation, can not cause larger leakage problem;
2, spring detent is equipped with in the present invention, can carry out locking to valve by fluid,matching pressing system, is that valve sealing is safer.
The present invention has novel structure, processes the advantages such as easy, esy to use, safe and reliable, and it puts goods on the market in enormous quantities and will produce positive social benefit and significant economic benefit.
Accompanying drawing explanation
The present invention has 1 width accompanying drawing, wherein:
Accompanying drawing 1 structural representation of the present invention.
In the drawings: 1, pipeline 2, support 3, oil hydraulic cylinder 4, piston rod 5, boss 6, spring detent 7, through hole 8, seal ring 9, plug 10, gas outlet 11, valve body 12, Imported gas.
Embodiment
Specific embodiments of the invention as shown in drawings, are made up of valve body 11 and oil hydraulic cylinder 3; It is characterized in that being processed with Imported gas 12 and gas outlet 10 on valve body 11, on the valve wall of the opposite of Imported gas 12, be processed with through hole 7; Support 2 is loaded on valve body 11, and oil hydraulic cylinder 3 is loaded in support 2, and the piston rod 4 of oil hydraulic cylinder 3 enters in valve body 11 through the through hole 7 on valve body 11, and in the front portion of piston rod 4, plug 9 is housed; Oil hydraulic cylinder 3 is connected with external hydraulic system by pipeline 1; Valve body 11 inwalls scribble amine curing agent coating.
On piston rod 4, be processed with boss 5, boss 5 is used in conjunction with the spring detent 6 being loaded on support 2 sidewalls.
Seal ring 8 is housed on through hole 7.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; allly be familiar with those skilled in the art in technical scope disclosed by the invention, within being equal to and replacing or change protection scope of the present invention all should be encompassed according to technological scheme of the present invention and design of the present invention thereof.
