Description

Technical Field

[0001] The present invention relates to the technical field of vacuum pressure control valves, and in particular to a vacuum pressure control valve based on a central opening and closing method. Background Art

[0002] The vacuum pressure control valve is installed between equipment to control the pressure of the process chamber smoothly. At this time, the sealing plate of existing foreign products starts from the edge of the flow path. Open or close to control the pressure. If it is controlled from the center of the flow path with the largest flow, the pressure can be controlled faster and more efficiently.

[0003] During use, the existing vacuum pressure control valve mostly achieves blocking of the flow channel by setting a swinging rotating plate structure. However, when the single plate swings, the water flow will be subjected to a large impact force on the lateral surface, so that a large power is required to achieve blocking of the flow channel.

[0004] Therefore, when the above-mentioned vacuum pressure control valve is used, the swing-type sealing method often requires unidirectional cutting of the flow channel during sealing, which causes the motor to output a larger power, thus easily affecting the service life of the entire vacuum pressure control valve. Summary of the invention

[0005] In order to overcome the problem that the swinging rotation of the existing vacuum pressure control valve can only cut the flow channel in one direction during use, which easily affects the service life of the entire vacuum pressure control valve to a certain extent.

[0006] The technical solution of the present invention is: a vacuum pressure control valve based on a central opening and closing method, comprising a valve housing assembly, a valve plate assembly connected to the valve housing assembly, a driving assembly connected to the valve housing assembly, a buffer assembly movably connected to the valve housing assembly, and a rotating assembly connected to the valve housing assembly, wherein the driving assembly is used to drive the buffer assembly to reciprocate around the central axis of the buffer assembly, the buffer assembly is used to impact a water body moving from top to bottom, and the rotating assembly is used to guide the water body entering the valve housing assembly; The valve plate assembly includes a driving assembly connected to the valve housing assembly and a rotating plate assembly connected to the driving assembly. The driving assembly is used to drive the rotating plate assembly to rotate around the central axis of the driving assembly, and the rotating plate assembly is used to control the opening and closing of the valve housing assembly.

[0008] Preferably, the rotating plate assembly comprises a first valve plate connected to the first housing, a second valve plate connected to the second housing, and buffer strips respectively connected to the first valve plate and the second valve plate.

[0009] Preferably, the valve housing assembly includes a protective cover connected to the first motor, a fixed valve housing connected to the protective cover, a first flange connected to the fixed valve housing, a second flange connected to the rotating assembly, and a partition assembly connected to the inner wall of the fixed valve housing.

[0010] Preferably, the partition assembly includes a partition plate connected to the inner wall of the fixed valve housing and a liquid passage pipe connected to the partition plate.

[0011] Preferably, the drive assembly includes a motor cover connected to the fixed valve housing, a second motor connected to the motor cover, a drive gear connected to the output shaft of the second motor, and a connecting frame movably connected to the drive gear.

[0012] Preferably, the buffer assembly includes a combination frame respectively arranged at the front and rear ends of both sides of the connecting frame, a synchronization gear movably connected to the combination frame, a synchronization assembly connected to the synchronization gear, a fixed rod connected to the synchronization assembly, and a liquid-discharging plate connected to the fixed rod.

[0015] Preferably, the guide assembly comprises a rotating cylinder movably connected to the fixed valve housing and a plurality of guide vanes connected to the rotating cylinder.

[0016] Beneficial effects of the present invention: 1. On the basis of the conventional vacuum pressure control valve, the method of closing the flow channel is improved so that the first motor can drive the first valve plate and the second valve plate to cut the flow channel on both sides respectively during the rotation process, thereby reducing the power output of the motor when driving the valve plate to rotate to a certain extent, thereby solving the problem that the swing-type rotation of the existing vacuum pressure control valve can only cut the flow channel in one direction during use, thereby easily affecting the service life of the entire vacuum pressure control valve to a certain extent; 2. After the valve plate seals the flow channel, the water inside the valve hits the valve plate, which will produce a certain amount of backflow, thereby causing water hammer to a certain extent, resulting in an increase in the internal pressure of the control valve, which will cause damage to the control valve. The vacuum pressure control valve can drive the buffer component to swing back and forth through the driving component, so that the two reciprocating liquid-splitting plates hit the falling water to relieve the pressure generated by the water during the falling process, thereby further improving the service life of the entire vacuum pressure control valve.
