Embodiment Construction

[0032] This embodiment provides a connection structure between the valve seat and the valve body of the check valve, such as figure 2 As shown, it includes a valve body 21, and a valve seat 22 located on the inner wall of the valve body 21 and sealingly connected with the valve body 21, and also includes a fixing structure 23 for fixing the valve seat 22 on the valve body 21. The fixing structure 23 includes a relatively The valve body 21 is provided with a limiting member 231 axially limited, and a fastener 232 for fixedly connecting the limiting member 231 with the valve seat 22 .

[0033] The above-mentioned technical solution is the core technical solution of the present invention. The limiting member 231 in the fixed structure 23 is set relative to the axial limit of the valve body 21, and is used to limit the valve seat 22 on the inner wall of the valve body 21. The fastener 232 is used for The stopper 231 is fixedly connected to the valve seat 22, and the fixation betw...

Abstract

The invention relates to a connecting structure of a valve seat and a valve body of a check valve. The connecting structure comprises a valve body, a valve seat and a fixing structure. The valve seat is arranged on the inner wall of the valve body and is tightly connected with the valve body, the fixing structure is used for fixing the valve seat on the valve body and comprises a locating part and a fastener, the locating part is axially arranged opposite to the valve body in a locating manner, and the fastener is used for fixedly connecting the locating part and the valve seat. The valve body is fixed on the valve seat via the locating part and the fastener; with the fixing structure, dismounting between the valve body and the valve seat is easy to realize and the fixing structure is stable in connection; the parts above is easy to be manufactured by manufacturers.

Description

technical field [0001] The invention belongs to the field of valves, and in particular relates to a connection structure between a valve seat and a valve body of a check valve. Background technique [0002] Check valves are mainly used in pipelines where the medium flows in one direction, and only allow the medium to flow in one direction to prevent reverse flow accidents. The valve seat of the check valve is fixed on the valve body to support the valve disc and form a sealing pair with it. The disc of the check valve is opened under the pressure of the flowing medium, and the flowing medium flows into the valve body from the inlet end of the valve body channel formed by the valve body and flows out from the outlet end. When the pressure at the inlet port is lower than that at the outlet port, the disc will automatically close under the action of factors such as the pressure difference of the flowing medium and its own gravity to prevent the medium from flowing backward. ...
