Abstract
The utility model discloses a decompression operation gas quantity saving device which comprises a pressure regulator and a one-way valve. One end of the pressure regulator is connected with an upstream diffuse pipe which is connected with an upstream pipeline, an upstream diffuse valve is arranged on the upstream diffuse pipe, the other end of the pressure regulator is connected with a one-way valve gas inlet end, a one-way valve gas outlet end is connected with a downstream diffuse pipe which is connected with a downstream pipeline, a downstream diffuse valve is arranged on the downstream diffuse pipe, and a main control valve is arranged between the upstream pipeline and the downstream pipeline. A quick coupler is arranged on a connecting pipeline of the pressure regulator and the upstream diffuse pipe and/or a connecting pipeline between the pressure regulator and the downstream diffuse pipe, and the quick coupler comprises a male head and a female head which are used in cooperation with each other. The device can reduce the diffused gas quantity of natural gas, avoid resource waste and environmental pollution and be convenient to mount and use.
Description
Technical field
The utility model relates to a kind of step-down operation tolerance saveall, belongs to city natural gas pipeline construction and installation field.
Background technique
After natural gas line comes into operation, due to user's continuous increase, need to often carry out extension and the opening arm of main pipe, band gas tipping terminal use.When wiring operation under pressure, need to carry out step-down operation at present, diffuse a large amount of rock gases and complete newly-built pipeline and move docking of pipeline, cause the wasting of resources and environmental pollution.
Model utility content
The purpose of this utility model is to provide a kind of step-down operation tolerance saveall, and this device can reduce the tolerance of diffusing of rock gas.
The technical solution that the utility model adopts is:
A kind of step-down operation tolerance saveall, comprise pressure governor and one-way valve, connection upstream, one end exhaust stack of pressure governor, upstream exhaust stack connects upstream line, is provided with upstream diffusion valve on the exhaust stack of upstream, and the other end of pressure governor connects one-way valve inlet end, connection downstream, one-way valve outlet side exhaust stack, downstream exhaust stack connects downstream line, is provided with downstream diffusion valve on the exhaust stack of downstream, is provided with master control valve between upstream line and downstream line.
Preferably, on the connecting tube of pressure governor and upstream exhaust stack and/or on the connecting tube of pressure governor and downstream exhaust stack, be provided with ready-packaged joint, ready-packaged joint comprises male and the female being used in combination.
Preferably, on the exhaust stack of downstream, connect an arm, on arm, be provided with pressure gauge and sampling cock.
Useful technique effect of the present utility model is:
The utility model can reduce the tolerance of diffusing of rock gas, avoids the wasting of resources and environmental pollution, easy to install, also can save the activity duration in addition, guarantees user's just conventional gas, and Security is good.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
Fig. 1 is the structural principle schematic diagram of a kind of mode of execution of the utility model.
In figure: 1-pressure governor, 2-one-way valve, 3-upstream exhaust stack, 4-upstream line, 5-upstream diffusion valve, 6-downstream exhaust stack, 7-downstream line, 8-downstream diffusion valve, 9-master control valve, 10-arm, 11-pressure gauge, 12-sampling cock, 13-ready-packaged joint.
Embodiment
By reference to the accompanying drawings, a kind of step-down operation tolerance saveall, comprises pressure governor 1 and one-way valve 2, connection upstream, one end exhaust stack 3 of pressure governor 1, and upstream exhaust stack 3 connects upstream line 4, is provided with upstream diffusion valve 5 on upstream exhaust stack 3.The other end of pressure governor 1 connects the inlet end of one-way valve 2, connection downstream, the outlet side exhaust stack 6 of one-way valve 2, and downstream exhaust stack 6 connects downstream line 7, is provided with downstream diffusion valve 8 on downstream exhaust stack 6.Between upstream line 4 and downstream line 7, be provided with master control valve 9.On downstream exhaust stack 6, connect an arm 10, on arm 10, be provided with pressure gauge 11 and sampling cock 12.
As to further improvement of the utility model, on the connecting tube of pressure governor 1 and upstream exhaust stack 3, be provided with ready-packaged joint 13, ready-packaged joint 13 comprises male and the female being used in combination.Male is arranged on the pipe end that connects pressure governor, and female is arranged on the end of upstream exhaust stack 3.The setting of ready-packaged joint 13 can make pressure governor 1 more simple and efficient with being connected of upstream exhaust stack 3.
Usage mode of the present utility model is roughly as follows:
After pressure governor 1 being installed on the exhaust stack at operation under pressure master control valve 9 two ends, can close in advance operation under pressure master control valve 9, make downstream user use the combustion gas in downstream line 7, downstream line 7 internal pressures continue to reduce, after the pressure that manifold pressure is set lower than pressure governor 1, now one-way valve 2 is opened pipeline 7 tonifying Qi downstream, guarantees user's just conventional gas.When, after the past pressure governor 1 cutting out with gas peak, complete pipeline and diffuse operation.
The relevant technologies content of not addressing in aforesaid way is taked or is used for reference prior art and can realize.
It should be noted that, under the instruction of this specification, any equivalents that those skilled in the art have done, or obvious variant, all should be within protection domain of the present utility model.
