Abstract

The invention provides an embedded one-way valve. The embedded one-way valve is assembled and connected with a main machine and comprises a spring seat, a spring, a sealing ball, a valve body and a guide sleeve, the spring seat is in a cup body shape, the opening of the spring seat is opened outwards, and a through hole is formed in the cup bottom surface of the spring seat; and the valve body isthe hollow cylinder body, the inner wall of the valve body comprises a step part protruding inwards in a radial mode, the spring seat is fixedly connected with one end of the valve body, after connecting, a storing space is formed by the spring seat and the step part, the spring and the sealing ball are placed in the storing space, the sealing ball is propped against the step part under the tension action of the spring, the side, facing the sealing ball, of the step part is provided with a conical surface, the guide sleeve is of a hollow cylinder and is in riveting connection with the other end of the valve body. The one-way valve has the simple and compact structure, is designed into a built-in type, placed in the main machine, and improves the assembly speed of the main machine.

Description

technical field [0001] The invention relates to the technical field of one-way valves in the mechanical industry, in particular to a one-way valve with an embedded structure. Background technique [0002] A check valve is a valve that allows the fluid to flow only along the inlet, but the outlet medium cannot return; this valve is widely used in many fields, and is often used in the hydraulic system to prevent the reverse flow of oil in the mechanical field, or in the pneumatic system Prevent reverse flow of compressed air. [0003] In terms of installation methods, there are two types of check valves: straight-through and right-angle; straight-through check valves are installed on the pipeline with threaded connections, and right-angle check valves are available in three forms: threaded connections, plate connections and flange connections. Regardless of the installation method, it needs to be assembled with internal threads and external threads to be fixed on the pipeline...
