Embodiment 1

[0016] Such as figure 1 , figure 2 , image 3 As shown, a variable-diameter check valve includes a variable-diameter check valve body 1, a variable-diameter check valve disc 2, and a variable-diameter check valve seat 3. It is characterized in that: the variable-diameter check valve The end of the valve body 1 with a larger inner diameter is the water inlet end 1A, and the end with a smaller inner diameter is the water outlet end 1B. The valve seat 3 of the variable diameter check valve is installed on the water inlet end 1A of the variable diameter check valve body using an O-ring 4 On the inner surface of the cavity, the variable-diameter check valve seat 3 installed on the inner surface of the variable-diameter check valve body water inlet 1A cavity is located in the cavity of the variable-diameter check valve body 1 using an O-ring 4 The end face is the sealing surface 31 sealingly connected with the variable diameter check valve disc 2; it also includes the variable di...

Abstract

The invention discloses a reducing check valve. The reducing check valve comprises a reducing check valve body, a reducing check valve clack, a reducing check valve seat, a reducing check valve clack mounting shaft, a water inlet end reducing check valve clack mounting shaft sleeve, three water inlet end reducing check valve clack mounting shaft sleeve fixing strip-shaped blocks, a water outlet end reducing check valve clack mounting shaft sleeve, and a water outlet end reducing check valve clack mounting shaft sleeve fixing strip-shaped block. A reducing check valve clack reset sealing spring is installed on the part, located between the reducing check valve clack and the water outlet end reducing check valve clack mounting shaft sleeve, of the reducing check valve clack mounting shaft. Reducing assembly connection of system pipelines is conveniently achieved, the number of pipeline reducing assembly connection pipe fittings is reduced, the mounting cost of the system pipelines is reduced, and the size and the mounting space of a pipeline reducing assembly combination are reduced; and the purpose of outlet water diversion is also conveniently achieved.

Description

technical field [0001] The invention belongs to a check valve, in particular to a variable diameter check valve. Background technique [0002] In the installation of existing system pipelines, when encountering changes in the flow rate of pipelines with variable diameters, it is necessary to use a variable diameter pipe fitting and a water separator. In order to prevent backflow, a check valve also needs to be installed. The existing system pipes are complicated to assemble and connect with variable diameters, and the installation is troublesome. Many connecting pipes are used, which increases the installation cost of the system pipes. How to conveniently realize the variable-diameter assembly and connection of the system pipes, reduce the number of pipe fittings used for the variable-diameter assembly and connection of the pipes, reduce the installation cost of the system pipes, and reduce the volume and installation space of the pipe variable-diameter assembly assembly are...
