Embodiment 1

[0021] The valve includes a fixed shaft 2; the upper and lower ends of the fixed shaft 2 are respectively provided with an upper fixed plate 7 and a lower fixed plate 1, and a side fixed bracket 9 is installed in the middle; a rubber tube 8 is fixed between the upper fixed plate 7 and the lower fixed plate 1 ; The rubber tube 8 is a pressure-resistant and heat-resistant material, and the rubber tube 8 can be disassembled and replaced. The side fixing bracket 9 is provided with a cylinder 22, the cylinder 22 is connected with the linkage mechanism, the linkage mechanism is connected with the pneumatic structure, and the linkage mechanism is located at the side of the rubber tube 8.

[0022] The pneumatic structure includes a cylinder connecting rod 15 and a throat clamp 16, the cylinder connecting rod 15 is connected with the cylinder 22, and the pneumatic structure is driven by the cylinder 22 to perform linear motion up and down; the cylinder is fixed on the side fixing bracke...

Embodiment 2

[0028] The difference from Embodiment 1 is that a small motor is used instead of the cylinder 22 to be fixed on the side fixing bracket 9, and a third connecting plate connects the throat clamp 16 and the small motor to replace the cylinder structure. When the vacuum system issues an action command, the motor rotates, driving the third connecting plate to move upwards, and at the same time, the second connecting plate 19, the second connecting rod 17, and the stopper 18 move along the guide groove of the side fixing bracket 9 to squeeze the rubber tube 8, so that The rubber tube 8 is in a closed state to maintain the vacuum degree requirement in the vacuum system. The valve drives the elastic rubber tube through the motor to realize the opening and closing of the rubber tube to meet the sealing requirements of the vacuum system.

Abstract

The invention provides a novel vacuum valve. The valve comprises a fixed shaft; an upper fixing plate and a lower fixing plate are correspondingly arranged at the upper end and the lower end of the fixed shaft, and a side fixing support is installed in the middle; a rubber pipe is fixed between the upper fixing plate and the lower fixing plate; and an air cylinder is arranged on the side fixing support and connected with a connecting rod mechanism through a pneumatic structure, and the connecting rod mechanism is located at the side edge of the rubber pipe. When the novel vacuum valve acts, the connecting rod mechanism is driven by the air cylinder to move along a guide groove of the side fixing support, the rubber pipe is opened and closed by loosening and extruding the rubber pipe, and therefore the sealing requirement of a vacuum system is met. The novel vacuum valve simplifies the structure of the valve, the structure of the valve is simplified, and the novel vacuum valve is simpler than an existing valve in the aspect of maintenance, does not need to be integrally disassembled, and only needs to replace the rubber pipe.

Description

technical field [0001] The invention relates to the field of valves, in particular to a novel vacuum valve. Background technique [0002] The vacuum system is a complete set of vacuum system composed of vacuum pump, PLC program control system, gas storage tank, vacuum pipeline, vacuum valve, overseas filter assembly, etc. In the vacuum system, the components of the vacuum system used to change the direction of the air flow, adjust the size of the air flow, and cut off or connect the pipeline are called vacuum valves. The vacuum valve is the main actuator and is the core component of the vacuum system. Vacuum valves mainly include flapper valves, inflation valves, flapper valves, ball valves, flap valves, fine-tuning valves, butterfly valves, differential pressure valves, and diaphragm valves; the existing valves mainly use slide valves and disc valves. However, these commonly used valve structures are stuck, which leads to system failure. After a failure, the product can on...
