Problems solved by technology
[0002] Most of the existing pneumatic valves adopt the structure of double gate pneumatic valve. The disadvantage of the existing pneumatic valve is that the structure is relatively complicated, especially the pneumatic valve with double gate structure needs to ensure that the gate is close to the valve shell. It is difficult to install compression springs on both sides of the gate, and it has to move up and down with the driving cylinder, resulting in serious wear of the gasket on the inner wall of the gate, and it is also difficult to operate, and the wind pressure resistance is large when closing and opening. And the most important thing is that the wind pressure and flow cannot be adjusted, only simple opening and closing

Embodiment Construction
[0013] The present invention will be further illustrated below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0014] Such as figure 1 As shown, a pair of hole-type pneumatic valve includes a valve housing 1, the upper end of the valve housing 1 is set as a valve inlet 2, and the lower end side wall of the valve housing 1 is provided with a valve outlet 3; and the valve housing A horizontally arranged fixed sealing plate 4 is also installed in the body 1, and the fixed sealing plate 4 is arranged above the valve outlet 3; the same drive device 5 is also installed on the lower end of the valve housing 1, and the drive device 5 The driving rod 51 extends into the valve housing 1 from the lower end...

The invention discloses an opposite-hole-type pneumatic valve which comprises a valve shell. A valve inlet is formed in the upper end of the valve shell, and valve outlets are formed in the side wallof the lower end of the valve shell; a transversely-arranged fixed sealing plate is further mounted in the valve shell and arranged above the valve outlets; the same driving device is further mountedat the lower end of the valve shell; and a driving rod of the driving device extends from the lower end of the valve shell into the valve shell, and a moving sealing plate is further mounted at the end of the driving rod. Through overlapped valve hole design, the valve can be opened and closed, the structure is simple operation is convenient, and very high sealing performance is achieved.
Description
technical field [0001] The invention relates to a valve part, in particular to a paired-hole pneumatic valve. Background technique [0002] Most of the existing pneumatic valves adopt the structure of double gate pneumatic valve. The disadvantage of the existing pneumatic valve is that the structure is relatively complicated, especially the pneumatic valve with double gate structure needs to ensure that the gate is close to the valve shell. It is difficult to install compression springs on both sides of the gate, and it has to move up and down with the driving cylinder, resulting in serious wear of the gasket on the inner wall of the gate, and it is also difficult to operate, and the wind pressure resistance is large when closing and opening. And the most important thing is that the wind pressure and flow cannot be adjusted, it can only be opened and closed simply. Contents of the invention [0003] The object of the present invention is to provide a paired-hole pneumatic...
