The pressure mechanism further comprises a check valve and air outlet, wherein the check valve is arranged in the center of the cylinder bottom, a limiting cover is arranged on the upper portion of the check valve, a filter screen is arranged on the lower portion of the check valve, and the air outlet is formed in the periphery of the lower portion of the cylinder sleeve and provided with the check valve. The pressure testing pipeline comprises a pressure testing flexible pipe, a pressure gauge, a control valve and quick joints, wherein the pressure gauge is arranged on the pressure testing flexible pipe, the control valve is arranged on the pressure testing flexible pipe in front of the pressure gauge, and the quick joints are arranged at the front end and the rear end of the pressure testing flexible pipe. The portable type non-hone-entry natural gas pipeline leak-testing device can carry out pressure testing and leak testing on minority users away from home through the pressure mechanism and the pressure testing pipeline, system pressure testing is not influenced, the pressure testing efficiency of a natural gas pipeline is improved, gas can be timely supplied for users, and convenience is created for the users.
Description
Technical field
The utility model relates to a kind of gas pipeline equipment that leaks hunting, specifically a kind of portable gas pipeline leak-checking apparatus of not registering one's residence.
Background technique
At present, some residential buildings of oil field and new residential building of going into operation all will carry out the work that pressure testing is leaked hunting to user's air pipe before the rock gas of gas distributing system is entering the user, because some user jobs are busy or go on business or visit and stay out, the system pressure testing of making can not be carried out, not pressure testing just can not allow the rock gas of gas distributing system enter the user, prevents to cause fire, explode and injure because of the gas leakage of user's gas pipeline the generation of serious accident of people's life.Often, influence the gas of using of entire building, had a strong impact on the defeated staff's of gas working efficiency simultaneously because of one or two people stay out.
Summary of the invention
The purpose of this utility model provides a kind of portable gas pipeline leak-checking apparatus of not registering one's residence, and overcomes the defective that prior art exists.
The technical solution of the utility model realizes in the following manner:
The utility model comprises pressure mechanism and pressure testing pipeline, it is characterized in that cylinder cap, the cylinder bottom that is connected with the cylinder sleeve lower thread that pressure mechanism comprises cylinder sleeve, is threaded with cylinder sleeve top, is located at the piston of the band seal ring in the firm cover, is threaded with the piston center and vertical upper end of stretching out cylinder cap has the piston rod of pressurized handgrip; Also comprise be located at the cylinder bottom center go up the band limited cover, down with the one-way valve of filter screen be located at the gas outlet of the band one-way valve of cylinder sleeve lower, outer perimeter; The pressure testing pipeline comprises the pressure testing flexible pipe, be located at pressure gauge on the pressure testing flexible pipe, be located at the control valve on the pressure gauge front pressure testing flexible pipe and be located at the rapid pipe joint of pressure testing flexible pipe rear and front end.
Cylinder sleeve is made as cylindrical, and upper end portion and underpart are provided with box thread, and set air outlet, bottom is threaded with one-way valve, and the middle and upper part bilateral symmetry is provided with the braces hanger.
Cylinder bottom is made as cylindrical, upper diameter is little, lower diameter is big, central upper portion is provided with the cylindrical one-way valve limited cover that is threaded with cylinder bottom, the limited cover center is provided with air outlet hole, limited cover bottom cylinder bottom is provided with the one-way valve conical seat, conical seat is provided with the one-way valve ball sealer, and the conical seat bottom is provided with the concave hole greater than the conical seat internal diameter.
The user that the utility model is stayed out to minority by pressure mechanism and pressure testing pipeline pressure testing is separately leaked hunting, and does not influence system's pressure testing, has improved the pressure testing efficient of gas pipeline, can in time give user's air feed, has created convenience to user's usefulness gas.

Embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model comprises pressure mechanism and pressure testing pipeline, it is characterized in that cylinder cap 2, the cylinder bottom 8 that is connected with cylinder sleeve 3 lower thread that pressure mechanism comprises cylinder sleeve 3, is threaded with cylinder sleeve top, is located at the piston 5 of the band seal ring in the firm cover 3, is threaded with piston 5 centers and vertical upper end of stretching out cylinder cap 2 has the piston rod of pressurized handgrip 1; Also comprise be located at the cylinder bottom center go up band limited cover 6, down with the one-way valve 9 of filter screen be located at the gas outlet of the band one-way valve 9 of cylinder sleeve 3 lower, outer perimeter; The pressure testing pipeline comprises the pressure testing flexible pipe, be located at pressure gauge 10 on the pressure testing flexible pipe, be located at the control valve 11 on the pressure gauge 10 front pressure testing flexible pipes and be located at the rapid pipe joint 12 of pressure testing flexible pipe rear and front end.
When using the utility model, on braces hanger 4, fasten braces, carry the scene, the Manufacturing material of Yin Ben device all adopts plastic production, very light in weight, operate also more convenient, the rapid pipe joint of pressure testing hose end is connected with instrument connector in the instrument pond, portable pressurized handgrip 1 drives piston 5 up generation drafts, air jack-up ball sealer 7 behind strainer filtering enters in the cylinder sleeve 3 from limited cover 6, this moment, one-way valve 9 was closed, the hand pressurized handgrip, descent of piston, ball sealer is closed, one-way valve 9 is opened, enter user's supply air line by control valve 11 and rapid pipe joint 12, through repeatable operation, the pressure in the supply air line embodies from pressure gauge 10 gradually, if can not beat pressure, the supply air line leakage that this user is described is serious, if pressure tries 0.15Mpa, stablizes 5 minutes pressure and descends, the supply air line that this user is described has leakage, any one of both of these case arranged, can only turn off this user's source of the gas, give other user collective pressure testings again, wait this user's the people individual treated of returning, do not influence system's work pressure test.
