Description
Technical field
The present invention relates to a kind of sealing gasket, more particularly, to a kind of for nitrogen gas generator compresser cylinder cover plate
Sealing gasket.
Background technology
At present, in the compressor of nitrogen gas generator, sealing gasket quality is related to the service life of nitrogen gas generator.
The effect of sealing gasket is obstructed into gas storehouse and going out gas storehouse, in compressor operation, go out gas storehouse pressure can be more than into
Gas storehouse, cause sealing gasket gradually to offset, sealing gasket gas leakage can occur after long-time use.So in existing nitrogen
In gas generator maintenance process, changing sealing gasket must all be carried out.
In existing compressor service, sealing gasket is usually hour working time 6000-8000 (1 year or so)
It must be changed, and Renewal process is cumbersome, it is necessary to take compressor seal storehouse apart, roots out former sealing gasket.Work
Amount is big, and time-consuming, easily causes poorly sealed;And often opening gas-tight silo can reduce compressor service life.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of service life is long,
The sealing gasket for nitrogen gas generator compresser cylinder cover plate of good airproof performance.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of sealing gasket for nitrogen gas generator compresser cylinder, described cylinder are provided with cylinder cover plate junction
Air inlet, air intake duct, enter gas storehouse, gas outlet, gas off-take and go out gas storehouse, described air inlet, air intake duct and enter
Gas storehouse is interconnected, and gas outlet, gas off-take and goes out gas storehouse and is interconnected, and described sealing gasket is in the piece with hollow out
Shape, it is arranged between cylinder and cylinder cover plate, when piston moves in the cylinder, gas passes through air intake duct from air inlet
Gas storehouse is discharged out into entering gas storehouse, or from gas outlet by gas off-take,
Described sealing gasket includes barrier bar, and described barrier bar forms outlet storehouse and the interval entered between gas storehouse, made
The volume for going out gas storehouse is more than volume into gas storehouse.
Described barrier bar is V-shaped.
Described sealing gasket is provided with screwed hole, and for being connected with cylinder cover plate, cylinder cover plate is used to form closed loop
Border and radiating.
Described sealing gasket is provided with positioning hole, for the positioning between cylinder cover plate and cylinder, is set on cylinder cover plate
There are a circular protrusions, cylinder is provided with circular depressed, and during installation, circular protrusions are aligned through positioning hole with circular depressed,
It is easily installed for stable position.
Described sealing gasket is using sealing gasket made of graphite, has numerous remarkable sealing properties, as thermostabilization,
Self-lubricating, not corrosion-resistant, not aging, embrittlement etc., harshness working condition can use steady in a long-term, seldom
Need to safeguard.
Compared with prior art, the present invention has advantages below:
(1) obstruct bar and form outlet storehouse and the interval entered between gas storehouse, the volume for using gas storehouse is more than into gas storehouse
Volume, when go out gas storehouse because compression and air pressure rise when, due to go out gas storehouse space increase, so as to increase outlet
The compression area in storehouse, the pressure of gas storehouse is reduced out, reduce the side force that barrier is subject to, and then consolidated sealing
The service life of performance.
(2) when cover plate of compressor is pressed on sealing gasket, because barrier bar is V-shaped, have more than linear
Good vertical stability, makes barrier bar uniform force, and crooked, robust seal performance will not occur during stress.
(3) sealing gasket of other nitrogen gas generator compressors is compared, the sealing gasket after the present invention improves uses stone
Ink is made, and is no longer belong to safeguard the consumptive material in bag, and service life is in unlimited time, no longer needs to open gas-tight silo when safeguarding,
So as to also increase the service life of compressor;Maintenance time shortens, and saves time, sealing gasket and the cover plate of user
Maintenance, reduce maintenance cost, reduce product price.
(4) have a wide range of application, can be improved in the equipment for having oilless air compressor and oilless vacuum pump.
