Embodiment Construction

[0020] Depend on Figure 1-Figure 3 An adjustable multi-outlet synchronous valve according to the present invention is based on an adjustable synchronous valve with one inlet and two outlets as the basic unit. , the semi-through hole poppet valve 3 arranged symmetrically in the channel of the valve core 4 and its corresponding two cavities A cavity and B cavity, and the pressure compensating sliding sleeve 8 sequentially socketed outside the valve core 4, the reversing Sliding sleeve 5 and installation sleeve 9 are formed. The spool 4 is a cylindrical body with a recess in the middle, and the reversing sliding sleeve 5, the pressure compensation sliding sleeve 8 and the installation sleeve 9 are all hollow cylindrical structures and have corresponding hole groups, wherein the spool 4, The reversing sliding sleeve 5 and the pressure compensating sliding sleeve 8 can slide relative to each other.

[0021] The present invention is divided into two different structural forms: mu...

Abstract

The invention provides an adjustable multi-outlet synchronous valve. An adjustable synchronous valve with one inlet and two outlets serves as a basic unit, at least one or two basic units are arranged, and an additional unit connected through a first spiral connecting rod is additionally arranged on a valve element at the tail end of each basic unit; or a whole formed by connecting a second spiral connecting rod is arranged between any two adjacent basic units. The synchronous precision can be obviously improved, the application performance is obviously improved, the system back pressure is reduced, and the efficiency is improved. The traditional concept is changed, the processing technology is simplified, the processing difficulty is reduced, the size can be flexibly designed according to the field demand space, and the problem that the installation space is limited by the number and the size is effectively avoided; the device is novel in conception, compact and reasonable in structure, low in cost, long in service life and stable and reliable in performance, all application indexes have obvious advantages, and substantive features and remarkable progress are achieved.

Description

technical field [0001] The invention relates to a hydraulic synchronous valve, in particular to a parallel hydraulic synchronous valve with one inlet and multiple outlets, which can adapt to changes in inlet flow. Background technique [0002] According to market research and industry information, the structure of synchronous valves at home and abroad is a three-way structure with one input and two outputs. The synchronous valve with this structure can only be used to control two actuators. However, in the application field of hydraulic components, it is often encountered to control multiple (that is, more than two) actuators, such as synchronous valves to control the synchronization of multiple hydraulic cylinders or multiple hydraulic motors; It is realized by connecting multiple synchronous valves in series or in parallel. The tandem three-cylinder synchronous valve consists of a first-stage valve with a ratio of 2:1 and a second-stage synchronous valve with an equal rat...
