Description
Technical field
The utility model relates to a kind of natural gas compressing buffer device, particularly damping device before a kind of natural gas compressing.
Background technique
Along with the construction of west_east gas transmission pipeline, the end connection door station of pipeline, the end connection door station of pipeline, wholesale after rock gas part entrucking through station of moving into one's husband's household upon marriage, another part enters in gas storage well and carries out retail, compressed natural gas is the high flammable explosive gas of about 25Mpa, entering a rock gas at station is fluctuation-type air-suction state, fluctuation-type air-suction state easily causes the blocking of air inlet pipeline, affect normally entering of rock gas, gas enters not steady, easily causes the impact to compressor, affects the working life of compressor.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides damping device before a kind of natural gas compressing, and structure is simple, and working efficiency is high, avoids the problem that fluctuation-type air-suction state easily blocks air inlet pipeline.
Its technological scheme is: comprise cylinder body, suction port, air outlet, piston, piston rod, flexible sliding sleeve, coil tension spring, circlip, floating bushing, the top of cylinder body is provided with suction port and air outlet, the inside of described cylinder body is hollow structure, cylinder interior is divided into buffer chamber, be communicated with chamber, described buffer chamber connects suction port, be communicated with chamber and connect air outlet, the inside fixed piston of described cylinder body, the outer end of piston connects piston rod, the interior edge face of piston connects flexible sliding sleeve, the outside of described flexible sliding sleeve is provided with coil tension spring, the end face of flexible sliding sleeve fixes circlip, described flexible sliding sleeve and buffer chamber, be communicated with between chamber and be provided with through-flow mouth.
Floating bushing is provided with between above-mentioned piston and flexible sliding sleeve.
The inwall of above-mentioned connection chamber is spiral cell body.
The beneficial effects of the utility model are: structure is simple, and working efficiency is high, avoids the problem that fluctuation-type air-suction state easily blocks air inlet pipeline, ensure normally entering of rock gas, realize gas steadily to enter, decrease the impact of gas to compressor, improve the working life of compressor.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: cylinder body 1, suction port 2, air outlet 3, piston 4, piston rod 5, flexible sliding sleeve 6, coil tension spring 7, circlip 8, floating bushing 9, buffer chamber a, connection chamber b, through-flow mouth c.
Embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises cylinder body 1, suction port 2, air outlet 3, piston 4, piston rod 5, flexible sliding sleeve 6, coil tension spring 7, circlip 8, floating bushing 9, the top of cylinder body 1 is provided with suction port 2 and air outlet 3, the inside of described cylinder body 1 is hollow structure, cylinder body 1 inside is divided into buffer chamber a, be communicated with chamber b, described buffer chamber a connects suction port 2, be communicated with chamber b and connect air outlet 3, the inside fixed piston 4 of described cylinder body 1, the outer end of piston 4 connects piston rod 5, the interior edge face of piston 4 connects flexible sliding sleeve 6, the outside of described flexible sliding sleeve 6 is provided with coil tension spring 7, the end face of flexible sliding sleeve 6 fixes circlip 8, described flexible sliding sleeve 6 and buffer chamber a, be communicated with between chamber b and be provided with through-flow mouth c.
Wherein, floating bushing 9 is provided with between piston 4 and flexible sliding sleeve 6.
In addition, the inwall being communicated with chamber b is spiral cell body, and spiral chute body can alleviate the cushion effect of gas.
Working principle: floating bushing 9 is tightly pressed against on cylinder bottom ladder shrinkage pool shoulder end face under coil tension spring 5 with the active force being communicated with chamber, form end face seal, the gas of buffer chamber a cannot be discharged through air outlet by being communicated with chamber b smoothly, can only be communicated with through buffer chamber a, the through-flow mouth c be communicated with between chamber b.Along with the continuation of piston 7 is moved, coil tension spring 5 progressively compresses, and floating bushing 9 is close to and is combined on cylinder bottom 11 ladder shrinkage pool shoulder end face always, because the through-flow mouth c of throttling reduces gradually along with the increase of cushion stroke, drag effect increases gradually, piston 7 speed is slowed down, and buffer function is even.
The beneficial effects of the utility model are: structure is simple, and working efficiency is high, avoids the problem that fluctuation-type air-suction state easily blocks air inlet pipeline, ensure normally entering of rock gas, realize gas steadily to enter, decrease the impact of gas to compressor, improve the working life of compressor.
