Description
Technical field
This utility model relates to the valve gear of a kind of supplementary air accumulator gas.It is applicable to gas cylinder be filled with in air accumulator by gas in bottle, to ensure to be filled with air accumulator gas purity.
Background technology
Along with development and the progress of science and technology of national economy, many industries not only improve material performance requirement, also have higher standard to material finish, and vacuum heat can preferably ensure that material surface is bright and clean.In vacuum heat, cooling medium purity is to ensure that the key of material surface, is also the protection to vacuum equipment simultaneously, therefore cooling gas purity is increasingly paid attention to by each industrial undertaking.Relying on the performance that it is excellent, the use of vacuum heat treatment technology is increased by each commercial production day by day.But the cooling gas being filled with is impure, hinders the application of vacuum heat treatment technology, so for vacuum heat treatment equipment, gas purity should be improved as far as possible, to ensure workpiece surface quality after heat treatment.But at present, when holding vessel gas reduces, gas cylinder during make-up gas, has also introduced impurity in holding vessel, and impact is filled with gas purity in holding vessel, causes material surface to pollute, and shortens the service life of vacuum equipment simultaneously.
Utility model content
This utility model is for above-mentioned problems of the prior art, it is provided that the valve gear of a kind of supplementary air accumulator gas, solves the problem that make-up gas in prior art is impure, thus reduces material surface and pollute, increases the service life of vacuum equipment.
The technical solution of the utility model is as follows:
Supplement the valve gear of air accumulator gas, including breather, connection block, support spring and push-pull device at fixed, the both sides of breather are correspondingly arranged air inlet and gas outlet, the top of breather arranges through hole, the inner chamber of breather arranges connection block and supports spring, supports spring and is arranged on the bottom of connection block, supports spring and touches with connecting block, the top of connection block connects one end of push-pull device at fixed, and the other end of push-pull device at fixed stretches out breather；It is communicated with hole and blind hole, intercommunicating pore and blind hole on described connection block to communicate.
Slide 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 threadeded with breather.
The utility model has the advantages of as follows:
1, ensure that cylinder gas purity is consistent with holding vessel insufflation gas purity.
2, improve workpiece surface finish after heat treatment, protect vacuum equipment simultaneously, reduce production cost.
3, this device only needs handle of turn, so that it may all discharged by circuit air, simple to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of this utility model inflated condition.
Detailed description of the invention
Embodiment
As it can be seen, supplement the valve gear of air accumulator gas, including breather 1, connection block 2, supporting spring 3 and push-pull device at fixed, push-pull device at fixed is bolt bar 4, and bolt bar is threadeded with breather.The both sides of breather are correspondingly arranged air inlet 5 and gas outlet 6, and the top of breather arranges through hole 7, and through hole 7 is arranged on air inlet 5 and the top of gas outlet 6；The inner chamber of breather arranges connection block 2 and supports spring 3, supports spring 3 and is arranged on the bottom of connection block 2, supports spring 3 and touches with connecting block 2, and the top of connection block 2 connects one end of bolt bar 4, and the other end of bolt bar 4 stretches out breather；Being communicated with hole 8 and the setting arranged in parallel of blind hole 9, intercommunicating pore and blind hole on described connection block 2, intercommunicating pore and blind hole communicate.
Sliding respectively above and below described air inlet, gas outlet and be provided with seal gasket 10, seal gasket fits with connecting block, the sealing in sliding process, the flow direction of control insufflation gas.
During use, gas outlet connecting air accumulator, air inlet connects gas cylinder.Supporting spring and be in relaxed state, the intercommunicating pore of connection block is in connected state, when single air cylinder make-up gas in air accumulator with the through hole of breather, the valve of gas cylinder is opened, gas, from inlet charge, through blind hole, intercommunicating pore, is discharged in air to through hole.Treating that the gas in pipeline is discharged in air, connection block is screwed in downwards by bolt bar, and the intercommunicating pore of connection block connects with air inlet and gas outlet, and gas enters in air accumulator through air inlet, intercommunicating pore, gas outlet.Treating that inflation completes, by bolt bar upwards spin-up, whole gas replenishment process terminates.
According to connecting line length, determine dead time, storage pressure is set to 0.4MPa, when the loading line length that described air inlet and gas outlet connect is not more than 1m, intercommunicating pore and through hole Lifetime are 2s, loading line length often increases by one meter, and Lifetime increases 1s, to ensure that the air in pipeline is discharged in air.
By great many of experiments and practice, make-up gas purity is played effective protective action by this utility model.
The above is specific embodiment of the utility model and the know-why used, any based on the equivalent transformation on the basis of technical solutions of the utility model, within belonging to protection domain of the present utility model.
