Check valve driving device and implementation method thereof

Abstract

The invention discloses a check valve driving device and an implementation method thereof, and belongs to the technical field of check valves. The check valve driving device comprises a valve body and a valve cover, wherein the valve cover and a top opening of the valve body is sealed with a bolt, a lifting rotating mechanism is installed on the valve cover, two ends of the valve body are correspondingly connected to an inlet and an outlet, and a check structure is installed at the joint of the inlet and the outlet. According to the check valve driving device and the implementation method thereof, the rotating mechanism is connected to a lifting mechanism located inside the valve body, the lifting mechanism drives the lifting mechanism to ascend or descend and is used for starting or stopping the check structure, and an air cylinder drives a piston rod to extend until an outer semi-arc plate collides with a blocking piece, so that a spherical shell is stopped, a micro motor is driven to work at the same time, when the inner semi-arc plate rotates to the direction perpendicular to the outer semi-arc plate, the two ends of the inner semi-arc plate abut against the two blocking pieces correspondingly, so that the spherical shell is locked, the connecting position of the inlet and the outlet is cut off, and non-return is achieved.

Description

technical field [0001] The invention relates to the technical field of check valves, in particular to a check valve driving device and an implementation method thereof. Background technique [0002] As a kind of valve, the check valve refers to a valve whose opening and closing part is a circular disc and acts by its own weight and medium pressure to block the backflow of the medium. Some deficiencies. [0003] The existing check valve is used in a single way, and can only be opened and closed in a single way. When the flow pressure of the liquid passing through the check valve increases, the impact force on the check valve is relatively large, which is easy to cause damage and shorten its life. In use, it cannot meet the needs of use. Some check valves use motor gears to drive the blades. Not only the gap between the two blades is poorly sealed, there is backflow, and the meshing error between the gears is large, which is not conducive to opening and closing control. Valv...

Problems solved by technology

[0003]The existing check valve is used in a single way, and can only be opened and closed in a single way. When the flow pressure of the liquid passing through the check valve increases, the check valve The impact force in the valve is relatively large, which is easy to cause damage, shortens its use, and cannot meet the needs of use. There are also check valves that use motor gears to drive the blades. Not only the gap between the two blades is poorly sealed, there is backflow phenomenon, Moreover, the meshing error between the gears is large, which is not conducive to the opening and closing control. The valve is an important part in the life and manufacturing process.
