Description
Technical field
The utility model relates to a kind of natural gas facility, particularly relates to a kind of natural gas depressurization Safety valve.
Background technique
At present, rock gas has become the third-largest energy except coal and oil, rock gas is mainly through Cemented filling, in course of conveying, rock gas is at a high speed or high pressure conditions, and needs low pressure natural gas when being transported to terminal use, and this just needs decompressor to carry out decompression adjustment to rock gas, the present most independent action of natural gas depressurization device, namely decompressor and switch valve act on respectively, which results in operational loaded down with trivial details, also improve manufacture cost.
Summary of the invention
The purpose of this utility model is just to provide a kind of natural gas depressurization Safety valve to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises valve body, knob, adjusting screw rod, film, spring cushion block, Regulation spring, valve, shutter spring, suction tude, steam outlet pipe, high pressure gauge, low-pressure meter, left low pressure chamber and right low pressure chamber, described knob and adjusting screw rod are connected to one, described adjusting screw rod is connected by screw thread and described valve body, described adjusting screw rod lower end is connected with Regulation spring, the lower end of described Regulation spring is fixed on spring cushion block, it is film below spring cushion block, described film is curved foil, valve is fixedly connected with bottom described film, described valve lower end is connected to by shutter spring on the base plate of described valve body, described valve and shutter spring are in the hyperbaric chamber of described valve body, both sides, hyperbaric chamber are respectively left low pressure chamber and right low pressure chamber.The left end in hyperbaric chamber is connected with suction tude, and described suction tude place is provided with high pressure gauge, and described right low pressure chamber is connected with steam outlet pipe and arranges low-pressure meter at described steam outlet pipe place.
The beneficial effects of the utility model are:
The utility model is a kind of natural gas depressurization Safety valve, and compared with prior art, the utility model has decompression and safety valve double action, and effect of easing stress is good, pressure adjustable, and Security is high, and structure is simple, easy to use, has the value applied.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of natural gas depressurization Safety valve described in the utility model.
In figure: 1-valve body, 2-knob, 3-adjusting screw rod, 4-film, 5-spring cushion block, 6-Regulation spring, 7-valve, 8-shutter spring, 9-suction tude, 10-steam outlet pipe, 11-high pressure gauge, 12-low-pressure meter, the left low pressure chamber of 13-, the right low pressure chamber of 14-.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the utility model comprises valve body 1, knob 2, adjusting screw rod 3, film 4, spring cushion block 5, Regulation spring 6, valve 7, shutter spring 8, suction tude 9, steam outlet pipe 10, high pressure gauge 11, low-pressure meter 12, left low pressure chamber 13 and right low pressure chamber 14, knob 2 and adjusting screw rod 3 are connected to one, adjusting screw rod 3 is connected by screw thread and valve body 1, adjusting screw rod 3 lower end is connected with Regulation spring 6, the lower end of Regulation spring 6 is fixed on spring cushion block 5, it is film 4 below spring cushion block 5, film 4 is curved foil, valve 7 is fixedly connected with bottom film 4, valve 7 lower end is connected to by shutter spring 8 on the base plate of valve body 1, valve 7 and shutter spring 8 are in the intermediate cavity of valve body 1, intermediate cavity both sides are respectively left low pressure chamber 13 and right low pressure chamber 14.The left end of intermediate cavity is connected with suction tude 9, and suction tude 9 place is provided with high pressure gauge 11, and right low pressure chamber 14 is connected with steam outlet pipe 10 and arranges low-pressure meter 12 at steam outlet pipe 10 place.
During use, rotate adjusting screw rod 3, compression adjustment spring 6, spring cushion block 5 and film 4, make valve 7 leave valve body 1.The pressurized gas of suction tude 9 enter left low pressure chamber 13 by hyperbaric chamber through the throttle clearance of valve 7 and valve body 1 and right low pressure chamber 14 spreads decompression.The pressure of high and low voltage chamber is indicated by high pressure gauge 11 and low-pressure meter 12 respectively.Post-decompression pressure turns adjusting screw rod 3 by left and right and regulates, and mainly change the pressure that Regulation spring 6 produces, the gas pressure causing film 4 to balance with it below changes to reach required working pressure.As long as complete loose adjusting screw rod 3 when finishing using, valve 7 can seal hyperbaric chamber outlet under the effect of pressurized gas active force and shutter spring 8 to carry out closedowns and seals.Suction tude 9 and steam outlet pipe 10 jointing are provided with sealing outside thread, to improve the tightness that pipeline connects.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technological scheme, all drops within protection domain of the present utility model.
