Problems solved by technology

Every use needs to open a hole and seal the processing inlet of the oil circuit, and it takes up a lot of space. It is impossible to arrange multiple check valves in a small space. For example, the space behind the flange of the hydraulic motor is already small, which brings great difficulties for processing, manufacturing and design. great difficulty

Abstract

The invention discloses a parallel integrated multi-stage one-way valve, and relates to the field of hydraulic valves. Comprising a valve body and a valve element assembly connected with the valve body, the valve element assembly is composed of at least one set of valve element units, and the valve element units are detachably arranged in sequence in an end-to-end mode; the valve element unit comprises a valve element, a first oil cavity and a second oil cavity are formed in the valve element, the inner diameter between the first oil cavity and the second oil cavity is gradually reduced, an oil sealing face is formed, the first oil cavity and the second oil cavity are provided with a first oil port and a second oil port, and a steel ball is arranged in the first oil cavity. Through the modular design of the valve body, the multi-stage one-way valve can be integrated in parallel, the stage number can be adjusted at will, and therefore the multi-stage one-way valve can be arranged in a narrow space, the space utilization rate is increased, and machining and manufacturing are easy.

Description

technical field [0001] The invention relates to the field of hydraulic valves, in particular to a parallel integrated multi-stage check valve. Background technique [0002] At present, check valves are widely used in various industries, especially in the hydraulic industry. The one-way valve is mainly composed of a valve body and a valve core (cone type, ball type), and some have a return spring. At present, the one-way valves in the industry and the market are basically used individually, and the forms include cartridge valves, integrated In the oil passage and so on. Every use needs to open a hole and seal the processing inlet of the oil circuit, and it takes up a lot of space. It is impossible to arrange multiple check valves in a small space. For example, the space behind the flange of the hydraulic motor is already small, which brings great difficulties for processing, manufacturing and design. Great difficulty came. Contents of the invention [0003] The purpose o...
