Description

Technical Field

[0001] The utility model relates to the technical field of throttle valve plate equipment, in particular to a throttle valve plate for a shock absorber. Background Art

[0002] In existing vacuum chambers, in order to control the flow of inert gas, a blade-type throttle valve is often used to control the flow rate; however, manual adjustment of the size of the switch is often used to control the switch closure state of the blade-type throttle valve; in actual production applications, it is impossible to achieve more precise control and automatic control of the switch closure of the blade-type throttle valve; the coating process cannot be automatically controlled, and at the same time, manual adjustment of the blade-type throttle valve is inconvenient to operate and the degree of switch closure cannot be controlled.

[0003] The application number is CN201721135246.5, which discloses a small multi-blade throttle valve for a vacuum chamber, including a flange, a fixed collar, blades, a main shaft, and a rotating actuator. A fixed collar is provided on the inner ring of the flange, and is characterized in that a plurality of blades are provided inside the fixed collar; the blades are symmetrically arranged in the upper and lower parts; a rotating shaft is riveted on the back of each blade; both ends of the rotating shaft pass through the fixed collar and are connected to the flange; an axle seat is provided above each blade; a groove is provided in the middle of each axle seat, and a shaft sleeve is provided in the groove; each shaft sleeve is connected in series with a linkage push rod; the rotating shaft on the symmetric axis of the flange passes through the fixed collar, the flange and the rotating actuator in turn; a multi-blade structure and a structure in which the blades are connected in series with a linkage push rod are adopted; while remote automatic control can be realized in conjunction with the rotating actuator, the opening and closing angles of the multi-blade throttle valve are controlled by the rotating actuator; the control accuracy of the multi-blade throttle valve is ensured.

[0004] The above document discloses a small multi-blade throttle valve for a vacuum chamber, which has the following defects: when the multi-blade throttle valve is opened and closed, multiple blade-shaped valve plates rotate back and forth. When the water flow hits the valve plate, it will bring a strong impact force. When the valve plate is damaged, the structure is not equipped with a corresponding detachable structure, which may cause the structure to be unable to normally intercept the water flow, thereby shortening the service life of the throttle valve.

[0005] It can be seen from this that the existing blade-type throttle valve does not have the function of disassembling and replacing the valve plate. It is necessary to improve the existing deficiencies and provide a function that can disassemble and replace the valve plate. Utility Model Content
