Description
Technical field
The present invention relates to a kind of valve gear for supplementing air accumulator gas.Gas in bottle is filled with gas storage suitable for gas cylinder
In tank, to ensure to be filled with air accumulator gas purity.
Background technology
With the development of national economy and the progress of science and technology, many industries not only improve material performance requirement, also right
Material finish has higher standard, and vacuum heat can preferably ensure that material surface is bright and clean.Vacuum heat
Middle cooling medium purity is to ensure the key of material surface, while is also the protection to vacuum equipment, therefore cooling gas purity is got over
Paid attention to get over by each industrial enterprise.By its excellent performance, each industrial production makes to vacuum heat treatment technology
With increasingly increasing.But the cooling gas being filled with is impure, the application of vacuum heat treatment technology is hindered, so for vacuum heat
Equipment, gas purity should be improved as far as possible, to ensure workpiece surface quality after being heat-treated.But at present, when holding vessel gas reduce,
Gas cylinder has also introduced impurity into holding vessel during make-up gas, and influence is filled with gas purity in holding vessel, causes material table
Face is polluted, and shortens the service life of vacuum equipment.
The content of the invention
The present invention is directed to above-mentioned problems of the prior art, there is provided a kind of valve gear for supplementing air accumulator gas,
Solve the problems, such as that make-up gas is impure in the prior art, so as to reduce material surface pollution, increase vacuum equipment uses the longevity
Life.
Technical scheme is as follows：
Supplement the valve gear of air accumulator gas, including air-breather, connection block, support spring and push-pull device at fixed, ventilation dress
The both sides put are correspondingly arranged air inlet and gas outlet, and the top of air-breather sets through hole, and the inner chamber of air-breather sets connection
Block and support spring, support spring are arranged on the bottom of connection block, and support spring touches with connecting block, connect the top connection of block
One end of push-pull device at fixed, the other end of push-pull device at fixed stretch out air-breather；Hole and blind hole are communicated with described connection block, even
Through hole and blind hole communicate.
Slided respectively above and below described air inlet, gas outlet and be provided with seal gasket.
Described seal gasket fits with connecting block.
Described through hole is arranged on the top of air inlet and gas outlet.
Described intercommunicating pore and blind hole setting arranged in parallel.
Described push-pull device at fixed is bolt bar, and bolt bar is threadedly coupled with air-breather.
Advantages of the present invention effect is as follows：
1st, it is consistent can to ensure that cylinder gas purity with holding vessel is filled with gas purity.
2nd, workpiece surface finish after being heat-treated is improved, while protects vacuum equipment；, reduce production cost.
3rd, the device only needs handle of turn, so that it may circuit air is all discharged, it is simple to operate.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of inflated condition of the present invention.
Embodiment
Embodiment
As illustrated, the valve gear of supplement air accumulator gas, including air-breather 1, connection block 2, support spring 3 and push-and-pull
Device, push-pull device at fixed are bolt bar 4, and bolt bar is threadedly coupled with air-breather.The both sides of air-breather be correspondingly arranged into
Gas port 5 and gas outlet 6, the top of air-breather set through hole 7, and through hole 7 is arranged on the top of air inlet 5 and gas outlet 6；Ventilation
The inner chamber of device sets connection block 2 and support spring 3, and support spring 3 is arranged on the bottom of connection block 2, and support spring 3 is with connecting
Block 2 touches, and one end of the top connection bolt bar 4 of connection block 2, the other end of bolt bar 4 stretches out air-breather；Described
Hole 8 and blind hole 9 are communicated with connection block 2, intercommunicating pore and blind hole setting arranged in parallel, intercommunicating pore and blind hole communicate.
Slided respectively above and below described air inlet, gas outlet and be provided with seal gasket 10, seal gasket is with connecting
Block fits, and for the sealing in sliding process, control is filled with the flow direction of gas.
In use, gas outlet is connected into air accumulator, air inlet connection gas cylinder.Support spring is in relaxed state, connects block
Intercommunicating pore and the through hole of air-breather be in connected state, when single air cylinder make-up gas into air accumulator, by gas cylinder
Valve is opened, and gas, by blind hole, intercommunicating pore, is discharged in air from inlet charge to through hole.Treat that the gas in pipeline is discharged to
In air, bolt bar screws in block is connected downwards, and the intercommunicating pore for connecting block connects with air inlet and gas outlet, and gas is by entering
Gas port, intercommunicating pore, gas outlet enter in air accumulator.Treat that inflation is completed, bolt bar is spun up upwards, whole gas replenishment process knot
Beam.
According to connecting line length, dead time is determined, storage pressure is arranged to 0.4MPa, described air inlet and outlet
When the loading line length of mouth connection is not more than 1m, intercommunicating pore and through hole Lifetime are 2s, and loading line length often increases by one
Rice, Lifetime increase 1s, is discharged in air with the air ensured in pipeline.
By many experiments and practice, the present invention plays effective protective action to make-up gas purity.
The technical principle described above for being the specific embodiment of the present invention and being used, it is any to be based on technical solution of the present invention
On the basis of equivalent transformation, belong within protection scope of the present invention.
