Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1, the novel check valve of this embodiment includes a valve body 1, be provided with valve cavity 11 in the valve body 1, the top of valve cavity 11 is provided with valve gap 2, be provided with in the valve cavity 11 and follow valve clack 3 that the valve cavity 11 reciprocated, valve cavity 11's bottom is passed through disk seat 12 and inlet 13 intercommunication, valve cavity 11 and liquid outlet 14 intercommunication, the bottom of valve clack 3 is provided with gasket 4, is used for compressing tightly above-mentioned gasket 4 valve clack nut 5 bottom valve clack 3, the bottom of valve clack 3 is passed through gasket 4 contradicts disk seat 12.
In fig. 1, the liquid inlet 13 is located on the left side, the liquid outlet 14 is located on the right side, when the pressure at the liquid inlet 13 is higher, the liquid pushes the valve flap 3 open and then flows to the liquid outlet 14, and when the pressure at the liquid outlet 14 is higher, the liquid presses the valve flap 3 against the valve seat 12 to prevent the liquid from flowing to the liquid inlet 13. The valve body 1 is fixedly connected with the valve cover 2 through a flange.
The bottom of the valve clack 3 is provided with a screw rod downwards, and the valve clack nut 5 is connected with the screw rod through threads.
The bottom of the valve clack 3 is provided with a groove, the gasket 4 is positioned in the groove, and the bottom of the gasket 4 still extends out of the groove.
The side surface of the valve flap 3 is provided with a communication cavity 31, and the communication cavity 31 is communicated with the upper part of the valve cavity 11, so that the liquid pressure of the valve cavity 11 is the same as that of the liquid outlet 14.
The valve clack 3 is made of C4 stainless steel and is not easy to damage. The gasket 4 is made of polytetrafluoroethylene, and has the advantages of good elasticity, good sealing performance and long service life.
When the gasket 4 is worn, the gasket can be replaced in time, and the service life of the check valve is prolonged.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
