Abstract
The utility model discloses a pressure regulator for gas pipeline operation with gas, whose aim is to provide a pressure regulator for gas pipeline operation with gas with simple structure, quick and simple installation and strong reliability. Both sides of a bleeder are connected with a connecting fixed element and a first tee, and another end of the first tee is orderly connected with a mass flow dispersing valve and an automatic dispersing valve; a third end of the first tee is orderly connected with a protecting table stop valve and a second tee, and other two ends of the second tee are separately connected with a small flow dispersing valve and a pressure gauge. Range ability of the pressure regulator for gas pipeline operation with gas is large, which is convenient for installing and transporting; the pressure regulator for gas pipeline operation with gas is not affected by climate, and provided with clear numerical reading, high cognition level and exact reflection of the pressure. An interface can be led to outside of the well body, which is convenient for observing; without operation in the well, which safeguards safety of persons. Sending gas into air via the bleeder, which can avoid generation of a deflagration accident, such as fire, etc.
Description
Technical field
The utility model relates to the observation and control technology field of inflammable gas pressure piping, in particular, relates to the inflammable gas pipeline and is taking over operation and transforming the pipeline pressure regulating working conditions and the control gear of band gas construction in the operation.
Background technique
The step-down operation under pressure of stopping the supple of gas or steam is to carry out the wiring of construction operation when the gaseous-pressure in the pipeline is reduced to 300-500Pa, when gaseous-pressure is too high, in cutting and the welding process, the flame that the weld joint generates is long, influence operating personnel's operation, welding torch flame pressure or arc pressure are difficult to push down gaseous-pressure, cause the molten bath to be difficult for forming, and increased the outer discharge of combustion gas in the pipeline, gaseous-pressure is low, though effectively in operation, the gaseous-pressure in the controlling plumbing fixtures is difficulty of malleation, caliber is big more or perforate is bigger, more difficult control, and the oxygen that cutting or gas welding are used might be sneaked in the gas pipeline morely.When gaseous-pressure was lower than 200Pa, outside air just may be with in the streamed infiltration pipeline and reach the explosion limit scope.Therefore, in the pipeline control of gaseous-pressure very important, and need establish the special messenger and regulate.Adopt " U " type water manometer to carry out the pressure measurement of pipeline in the existing inflammable gas pipeline operation under pressure, operator by rule of thumb, the sensation pressure working condition.Its existing problems have:
1. range is limited, and the table body is in transportation and installation process, and is easily broken, and pressure measurement medium (water or other liquid) is subjected to variation of ambient temperature very big, measures pressure and can not accurately reflect true pressure, error is bigger, and visual difficulty affected by environment when using at the scene easily produces the people for looking reader error.
2. with the defective of pipeline Placement: when using " U " type water manometer, the table body mainly relies on rubber hose to be connected with pipeline, and mainly provide connection mouth during operation under pressure by diffusing facility in the conduit shaft body, need go deep into well body inside if connect " U " type of need table, certainly will cause the observation difficulty, and the tester enters in the well, has potential safety hazard.
3. " U " type pressure gauge can only the single display pressure data, can't regulate and control the pipeline pressure operating mode, can not satisfy the demand of operation under pressure.
4. the pressure regulation process operation is loaded down with trivial details.
During the pipeline pressure release in well the operating personnel combustion gas easily takes place poisons, and the gas of emitting to be deposited in groundlevel concentration bigger, easy deflagration accident having such as breaking out of fire.
The model utility content
The utility model is in order to overcome the deficiency on the prior art, to provide a kind of simple in structure, installs simple and directly rapidly, and good reliability can be realized the gas pipeline operation under pressure pressure regulator of safety work.
The utility model is achieved through the following technical solutions:
A kind of gas pipeline operation under pressure pressure regulator, it is characterized in that the exhaust stack two ends are connected with respectively is connected and fixed the part and first threeway, the other end of described first threeway is connected with big flow in turn and diffuses valve and diffuse valve automatically, the 3rd end of described first threeway is connected with in turn and protects the table pipe valve and second threeway, and the other two ends of described second threeway are connected with small flow respectively and diffuse valve and pressure gauge.
Described exhaust stack is the plastic-aluminum pipe.
Gas pipeline operation under pressure pressure regulator of the present utility model has following advantage:
1. range ability big (selecting certain range ability pressure meter by actual demand) is convenient to install and transportation, weatherproof, and clear reading, the cognition degree height, the pressure reflection is accurately.
2. interface can be caused the well external body, be convenient to observation, operation in the no well, personal security is protected.
3. not only can test the pipeline pressure working conditions change of operation under pressure at any time, and can regulate and control pipeline pressure according to the needs of operation under pressure, in order to ensure the safety of operation under pressure, the purpose that safety and stability is carried out reliably when reaching inflammable gas pipeline operation under pressure.
4. simple in structure, install simple and direct rapidly.
5. by exhaust stack combustion gas is put in the air, can avoid the generation of deflagration accident havings such as fire.
Description of drawings
Fig. 1 is the schematic representation of the utility model gas pipeline operation under pressure pressure regulator.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the schematic representation of the utility model gas pipeline operation under pressure pressure regulator, exhaust stack 2 two ends are connected with respectively and are connected and fixed the part 1 and first threeway 3, the other end of first threeway 3 is connected with big flow in turn and diffuses valve 4 and diffuse valve 5 automatically, the 3rd end of first threeway is connected with the other two ends of protecting table pipe valve 6 and second threeway, 8, the second threeways 8 in turn and is connected with small flow respectively and diffuses valve 9 and pressure gauge 7.Exhaust stack preferably adopts the plastic-aluminum pipe.Being connected and fixed part is the screw thread latch fitting, as locknut etc.Because pipeline diffuses mouth apart from the ground level disunity, can do a pipe nipple in addition, be used for being connected to adjust height with exhaust stack.
During use, will be connected and fixed part and be screwed in gas pipeline exhaust stack or condenser cylinder head, and open big flow and diffuse valve and can diffuse, and when reaching required pressure, diffuse valve automatically and close.Open subsequently and protect the table pipe valve, observe the scale number, as be higher than required pressure, can adjust small flow and diffuse valve, and see that table is adjusted to the required safety range of operation under pressure.
Although relate to a kind of gas pipeline operation under pressure pressure regulator and carried out special description disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
