A kind of copper bar air valve disclosed in the utility model, including valve body, bonnet, diaphragm, one is provided with valve body with the air inlet of sand-blasting machine exhaust connection and an exhaust outlet being connected with silencer and lays chamber to lay the diaphragm of the diaphragm, bonnet is arranged on valve body by fastener and diaphragm is arranged in diaphragm installation cavity, and a compressed air inlet being connected with compressed air source is provided with bonnet;A sealing surface to be sealed with diaphragm is provided with diaphragm installation cavity, is closed the inner of air inlet when diaphragm is bonded with sealing surface, copper exhaust valve closure;The inner of air inlet is opened when diaphragm separates with sealing surface, copper exhaust valve opening;Control pressure chamber is provided between diaphragm and the inner surface of bonnet, control pressure chamber connects with the compressed air inlet on bonnet, and the pressure change of control pressure intracavitary can be such that diaphragm is bonded with sealing surface with separating.It is consumable accessory that copper bar air valve of the present utility model, which only has diaphragm, so the cost safeguarded is than less expensive.

Description

A kind of copper bar air valve
Technical field
The utility model discloses a kind of air bleeding valve, particularly discloses one kind and is used for the self-bleeding copper bar gas of sand-blasting machine Valve.
Background technology
Sand-blasting machine in the market is of all kinds, and species is various, and air bleeding valve is even more multifarious, but knot substantially all be present Structure is complicated, the problems such as troublesome maintenance.
Utility model content
Technical problem to be solved in the utility model is complicated present in existing air bleeding valve, maintenance fiber crops The problems such as tired and a kind of copper bar air valve is provided.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of copper bar air valve, including valve body, bonnet, diaphragm, one and sand-blasting machine exhaust connection are provided with the valve body Air inlet and an exhaust outlet being connected with the silencer and chamber is laid to lay the diaphragm of the diaphragm, the bonnet leads to Fastener is crossed on the valve body, the diaphragm is arranged in the diaphragm installation cavity by the bonnet, in the bonnet On be provided with a compressed air inlet being connected with compressed air source;One and the diaphragm are provided with the diaphragm installation cavity The sealing surface to seal, when the diaphragm is bonded with the sealing surface, the diaphragm closes the inner of the air inlet, Make to separate between the air inlet and the exhaust outlet, the copper exhaust valve closure;When the diaphragm separates with the sealing surface, The diaphragm opens the inner of the air inlet, makes to turn between the air inlet and the exhaust outlet, the copper bar air valve Open;Control pressure chamber, the control pressure chamber and the valve are provided between the inner surface of the diaphragm and the bonnet The compressed air inlet connection covered, the pressure change of the control pressure intracavitary can be such that the diaphragm is pasted with the sealing surface Close with separating.
In a preferred embodiment of the present utility model, the air inlet, the control pressure chamber, the diaphragm, institute State compressed air inlet to be coaxially disposed, the axis of the axis of the exhaust outlet and the air inlet is mutually perpendicular to, the sealing surface The plane at place and the central axis of the diaphragm are mutually perpendicular to.
In one of the present utility model is preferable to carry out, the valve body is molded using brass casting.
As a result of technical scheme as above, operation principle of the present utility model is as follows:
Copper bar air valve of the present utility model is normally close valve, and air inlet thereon is connected to the abrasive can pressure of adding pressure type sand-blasting machine The exhaust ports of power cylinder.The intake valve of copper bar air valve and sand-blasting machine of the present utility model is correlation, is only stopping sandblasting When work, i.e., intake valve opens copper bar air valve of the present utility model and is at normally off, and this state can be sprayed Sand operation.After intake valve is closed, copper bar air valve of the present utility model with regard to relevance opening, discharge pressurized tank in air, That is pressure release.Compressed air inlet on bonnet is connected with compressed air always, and copper bar air valve of the present utility model is constantly in closing State, after sand-blasting machine is temporarily completed sandblasting operation, intake valve is closed, and causes the compressed air of air gas circuit to be discharged, due to sky The pressure of the compressed air of gas gas circuit is more than the compressed air pressure of control pressure intracavitary, and the compressed air pressure of air gas circuit pushes away Dynamic diaphragm leaves sealing surface, and copper bar air valve is opened, and the compressed air in abrasive can just causes out by the air bleeding valve discharge opened Mouth muffler.Thus complete the action of the exhaust pressure relief of a sand-blasting machine.Due to the pressure release of pressurized tank, the seal of pressurized tank It will open, the action for adding sand will be automatically performed.
The valve body of copper bar air valve of the present utility model is brass casting, and performance is relatively stable, designs accurate, ingenious, structure Simply, use condition constraint is smaller, and -10~40 DEG C of scopes can be used, and in China, most area can use, by the external world Factor influence is smaller, and using the larger 0.1~1MPa of pressure limit, it is consumable accessory that copper bar air valve of the present utility model, which only has diaphragm, So the cost safeguarded is than less expensive.
Brief description of the drawings
Fig. 1 is the structural representation of copper bar air valve of the present utility model.
Embodiment
Referring to Fig. 1, a kind of copper bar air valve for being provided in figure, including valve body 100, bonnet 200, diaphragm 300.
Valve body 100 using brass casting be molded, be provided with one with sand-blasting machine exhaust connection air inlet 110 and one with The exhaust outlet 120 and lay chamber 130 to lay the diaphragm of diaphragm 300 that silencer connects.
Bonnet 200 is arranged on valve body 100 by fastener such as soket head cap screw 210, and bonnet 200 pacifies diaphragm 300 In diaphragm installation cavity 130, a compressed air inlet 220 being connected with compressed air source is provided with bonnet 200, in film A sealing surface 131 to be sealed with diaphragm 300 is provided with piece installation cavity 130.
When diaphragm 300 is bonded with sealing surface 131, diaphragm 300 closes the inner of air inlet 110, makes air inlet 110 and row Separate between gas port 120, copper exhaust valve closure.When diaphragm 300 separates with sealing surface 131, diaphragm 300 is by air inlet 110 The inner is opened, and makes to turn between air inlet 110 and exhaust outlet 120, copper exhaust valve opening.
Control pressure chamber 400, control pressure chamber 400 and bonnet are provided between the inner surface of diaphragm 300 and bonnet 200 Compressed air inlet 220 on 200 connects, and the pressure change in control pressure chamber 400 can make diaphragm 300 and sealing surface 131 Fitting is with separating.
Air inlet 110, control pressure chamber 400, diaphragm 300, compressed air inlet 220 are coaxially disposed, the axle of exhaust outlet 120 The axis of line and air inlet 110 is mutually perpendicular to, and the plane and the central axis of diaphragm 300 where sealing surface 131 are mutually perpendicular to.
