Abstract

The invention provides a check valve with double valve clacks. The check valve comprises a valve body and a valve cover, wherein the valve body comprises a filtration part, a first connecting base anda second connecting base; an impurity filtration treatment device is arranged under the filtration part; the first end of the valve cover is connected with one end, away from the filtration part, ofthe first connecting base in a sealing manner, and a first through hole is formed in the valve cover; a chamber is arranged in the first connecting base; a second through hole is formed in the first connecting base, and the chamber communicates with the first through hole and the second through hole; a first valve clack, a second valve clack, a first elastic connecting device, a second elastic connecting device, a first sealing device and a second sealing device are also arranged in the first connecting base; a connecting tank is arranged on the first sealing device, and a first channel whichcommunicates with the connecting tank and the chamber is arranged on the first sealing device; and a second channel which communicates with the first through hole is arranged on the second sealing device. According to the check valve with the double valve clacks disclosed by the invention, through arrangement of the filtration part and the impurity filtration treatment device, an operation of thecheck valve is prevented from being affected by impurities; and due to arrangement of double-sealing, backward flowing of fluid is prevented, and the sealing performance is high.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a double disc 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. In some cases, there may be impurities in the fluid delivered by the check valve. The existing check valve filters the impurities by setting a filter inside the valve body. However, it does not have a device for filtering impurities, and the filtered impurities remain in the valve body and affect the valve body. work. Contents of the invention [0003] The invention provides a d...
