Background technology
Check-valves is the valve body that air compressor machine will be used in use, and main function is air compressor machine to single in air accumulator
To inflation when can play a part of non-return.
But present check-valves used in the market is all without outgassing hole, the gas on system pipeline is by another
A magnetic valve is connect to realize outgassing function, anti-locking system is felt suffocated, the problem of causing compressor can not carry out second of startup.
In addition, just all have that service life is short, and spring steel wire section occurs in long-term work on check-valve spring is general
Situation about splitting, check-valves non-return is caused to fail, the problem of jam and seal failure occur occurs.The valve body material of check-valves is copper
Alloy, easily aoxidized during long-term use, shorten the service life of check-valves.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of air compressor check valve with outgassing hole, structure letter
It is single, by designing 0.25mm normally opened outgassing hole in plug screw upper end, coordinate copper sintered filter core to use the work(for reaching outgassing and being vented
Can, it is ensured that compression function carries out second of No Load Start.
Technical scheme is used by the utility model solves its technical problem：A kind of air compressor machine with outgassing hole is provided to stop
Valve is returned, including valve body and bonnet, one end of described valve body are disposed with intake interface, the other end of described valve body is provided with valve
Lid, valve pad is installed on the inside of described bonnet, spring is installed between described valve pad and bonnet, described valve pad is by valve body
Interior air intake duct seals, and the inner radial of described valve body is disposed with outgassing passage, and the end of described outgassing passage is provided with
Plug screw, the inside of described plug screw are provided with filter core, the position radial arrangement corresponding with valve pad in the side wall of described valve body
There is outlet interface, the top of described plug screw is provided with outgassing hole between two parties.
Preferably, described filter core is copper sintered filter core.
Further preferably, a diameter of 0.25mm in described outgassing hole.
Further, gap is left between described filter core and the madial wall of plug screw.
Further, O shape sealing gaskets are installed between described valve body and bonnet.
Beneficial effect：A kind of air compressor check valve with outgassing hole is the utility model is related to, it is simple in construction, by plug screw
0.25mm normally opened outgassing hole is designed in upper end, coordinates copper sintered filter core to use the function of reaching outgassing and be vented, it is ensured that compressor
Second of No Load Start can be carried out, 200 DEG C of insulation 12h annealing, acceleration spring are carried out to the stainless steel spring of check-valves
The release of planted agent, to improve the service life of spring, processing is passivated to the valve body of copper alloy, to improve the anti-oxidant of valve body
Property and further improve valve service life.
Brief description of the drawings
Fig. 1 is main view of the present utility model locally half-sectional structure chart；
Fig. 2 is three-dimensional structure diagram of the present utility model.
Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
As shown in Figure 1-2, embodiment of the present utility model is related to a kind of air compressor check valve with outgassing hole, including valve
Body 1 and bonnet 2, one end of described valve body 1 are disposed with intake interface 10, and the other end of described valve body 1 is provided with bonnet 2,
The inner side of described bonnet 2 is provided with valve pad 5, and spring 3 is provided between described valve pad 5 and bonnet 2, and described valve pad 5 will
Air intake duct 12 in valve body 1 seals, and the inner radial of described valve body 1 is disposed with outgassing passage 9, described outgassing passage 9
End is provided with plug screw 6, and the inside of described plug screw 6 is provided with filter core 8, corresponding with valve pad 5 in the side wall of described valve body 1
Position radial arrangement have outlet interface 11, the top of described plug screw 6 is provided with outgassing hole 7 between two parties.
Operation principle as check-valves described in the utility model：When being compressed in work loading, gas caused by cylinder
Pressure enters from intake interface 10, overcomes the pressure of check-valve spring 3, valve pad 5 is opened, and pressure is transported into storage from outlet interface 11
Gas tank, and when the compressor is shut down, valve pad 5 switchs again under the effect of the pressure of air accumulator and spring 3, prevents inside air accumulator
Pressure pour in down a chimney in cylinder.
And it is always normally opened that check-valves air intake duct 12, which fills plug screw 6 and the 0.25mm of copper sintered filter core upper end hole, work as pressure
When contracting machine needs second of startup after shutting down, the gas on pipeline must be first vented, and compressor just carries out second and started, and now puts
Gas is exactly to be deflated by the 0.25mm holes of plug screw upper end, it is ensured that compressor can start for second.
Preferably, described filter core 8 is copper sintered filter core, and it is more commonly used, it is also relatively durable.
A diameter of 0.25mm in described outgassing hole 7.
Gap, convenient energy Quick air-discharge are left between described filter core 8 and the madial wall of plug screw 6.

The utility model is simple in construction, by designing 0.25mm normally opened outgassing hole in plug screw upper end, coordinates copper sintering filter
Core reaches the function of outgassing emptying to use, it is ensured that compression function carries out second of No Load Start, to the stainless steel bomb of check-valves
Spring carries out 200 DEG C of insulation 12h annealing, the release of acceleration spring planted agent, to improve the service life of spring, to copper alloy
Valve body be passivated processing, come improve the inoxidizability of valve body and further improve valve service life.
