Embodiment Construction

[0090] The electro-hydraulic valve, the outlet pressure control system and the inlet pressure control system proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific examples. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that all the drawings are in very simplified form and use inaccurate scales, which are only used to facilitate and clearly illustrate the purpose of implementing the present invention.

[0091] Such as figure 1 Shown is the structure of an electro-hydraulic valve provided by the present invention, which includes a main valve 1, a first control valve 2, and a second control valve 3;

[0092] The main valve 1 includes a main valve inlet port 11, a main valve outlet port 12 and a main valve upper chamber 13;

[0093] The inlet port 11 of the main valve communicates with the upper cavity 13 of the main v...

Abstract

The invention provides an electrohydraulic valve, an outlet pressure control system and an inlet pressure control system. The electrohydraulic valve comprises a main valve, a first control valve and a second control valve. The main valve comprises a main valve inlet end, a main valve outlet end and a main valve upper chamber, wherein the main valve inlet end communicates with the main valve upper chamber through a first guide pipe, the main valve outlet end communicates with the main valve upper chamber through a second guide pipe, the first control valve is arranged on the part, close to the main valve inlet end, of the first guide pipe, and the second control valve is arranged on the part, close to the main valve outlet end, of the second guide pipe. The electrohydraulic valve overcomes the defect that the valves in the market are single in function, and can achieve multiple functions when used in cooperation with different devices; and it can be achieved that the open degree of the valve body of the main valve is adjustable within the range of 0% to 100%, and stability is good.

Description

technical field [0001] The invention relates to an electro-hydraulic valve, an outlet pressure control system and an inlet pressure control system, belonging to the field of valve control. Background technique [0002] In the general piping system of the prior art, traditional control valves generally can only achieve a single function, such as pressure reducing valves for decompression, pressure relief valves for pipeline protection, flow control valves for flow control or liquid level control. Controlled liquid level control valves, etc., when the pipeline system needs to achieve different functions, it is necessary to configure valves with different functions, or replace new and different valves, resulting in overly complicated pipeline systems, increased costs, and difficult maintenance. Contents of the invention [0003] The purpose of the present invention is to provide an electro-hydraulic valve, an outlet pressure control system and an inlet pressure control system...
