The invention discloses a simple non-return valve comprising a valve body. Branch rods are radially welded to the top end and the bottom end of an inner cavity of the valve body correspondingly; a sliding rod is in inserted connection with the center of the inner cavity of the valve body in the vertical direction; the top end and the bottom end of the sliding rod are fixedly welded to the branch rods at the upper end and the lower end correspondingly; the sliding rod slidably penetrates through a first inserted connection hole and a second inserted connection of a first sealing block, a secondsealing block and a third sealing block sequentially; a first flow-limiting column is fixedly welded to the side wall of the top end of the inner cavity of the valve body, and a second flow-limitingcolumn is fixedly welded to the side wall of the bottom end of the inner cavity of the valve body; the sliding rod penetrates through the first flow-limiting column and the second flow-limiting columnsequentially and is not attached to the first flow-limiting column and the second flow-limiting column mutually; the first sealing block and the second sealing block are both located between the first flow-limiting column and the second flow-limiting column and matched with the first flow-limiting column and the second flow-limiting column mutually; and the third sealing block is located on the lower portion of the second flow-limiting column and matched with the second flow-limiting column mutually. The simple non-return valve is simple in structure, low in cost, capable of achieving the secondary non-return function, simple and practical.
Description
technical field [0001] The invention relates to the related application technical field of check valves, in particular to a simple check valve. Background technique [0002] Check valve refers to the valve that relies on the flow of the medium itself to automatically open and close the disc to prevent the backflow of the medium, also known as check valve, one-way valve, reverse flow valve and back pressure valve. The check valve is a kind of automatic valve, its main function is to prevent the reverse flow of the medium, the reverse rotation of the pump and the drive motor, and the discharge of the container medium. At present, the check valves on the market include the check valve body. Although the effect of the check valve body is good, the structure is relatively complicated and the structural strength is low. Use for the first time, saving costs. Contents of the invention [0003] The purpose of the present invention is to provide a simple check valve to solve the ...
