Detailed Description
The present invention will be further described with reference to the following embodiments.
Example 1
The valve comprises a fixed shaft 2; the upper end and the lower end of the fixed shaft 2 are respectively provided with an upper fixed plate 7 and a lower fixed plate 1, and the middle part is provided with a side fixed bracket 9; a rubber tube 8 is fixed between the upper fixing plate 7 and the lower fixing plate 1; the rubber tube 8 is made of pressure-resistant and heat-resistant materials, and the rubber tube 8 can be detached and replaced. And an air cylinder 22 is arranged on the side fixing support 9, the air cylinder 22 is connected with a connecting rod mechanism, the connecting rod mechanism is connected with a pneumatic structure, and the connecting rod mechanism is positioned on the side edge of the rubber tube 8.
The pneumatic structure comprises a cylinder connecting rod 15 and a throat hoop 16, the cylinder connecting rod 15 is connected with a cylinder 22, and the pneumatic structure is driven by the cylinder 22 to do vertical linear motion; the cylinder is fixed on the side fixing bracket 9 through a hexagon nut 5 and a cylinder fixing block 21, and the cylinder fixing block 21 is arranged in the middle of the upper fixing plate 7.
The connecting rod mechanism comprises a second connecting plate 19, a baffle piece 18 and a second connecting rod 17, the second connecting plate 19, the baffle piece 18 and the second connecting rod 17 are all installed in the guide groove of the side fixing support and act along the guide groove of the side fixing support to realize the opening and closing of the rubber tube 8; the second connecting plate 19 is fixedly connected with the first connecting plate 11 and the cylinder connecting rod 15 through a throat hoop 16.
The fixed shaft 2 is fixedly connected with the upper fixing plate 7 and the lower fixing plate 1 through an inner hexagonal socket head cap screw 25; the fixed shaft 2 and the side fixing bracket 9 are fixed through a cross recessed countersunk head screw 12 and a hexagon nut 5.
When the valve does not act, the rubber tube 8 is in an open state, when the vacuum degree in the vacuum system needs to be changed, the air cylinder 22 acts, the air cylinder 22 drives the air cylinder connecting rod 15 to move upwards, the second connecting plate 19, the second connecting rod 17 and the blocking piece 18 to act along the guide groove of the side fixing support 9, the rubber tube 8 is extruded, the rubber tube 8 is gradually pressed and closed, and the requirement of the vacuum degree in the vacuum system is maintained; the valve realizes the opening and closing of the rubber tube by driving the elastic rubber tube through the cylinder so as to meet the sealing requirement of a vacuum system.
