Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is that in the prior art, the pilot split control valve uses a high-pressure rubber hose to connect the pilot valve and the main valve to realize the complicated and cumbersome connection brought about by the adjacent frame operation, which takes a long time and is easy To solve the problem of wrong connection, provide a simple and rapid connection, the pilot valve and the main valve are connected by a multi-core tube to operate the pilot reversing valve adjacent to the frame

Abstract

The invention relates to a neighboring frame-operated pilot reversing valve, which comprises a pilot valve part, a main valve part, an inserting component and a multi-core pipe, wherein the inserting component comprises a liquid route intergraded socket and an plug, an interface face of the pilot valve part on the pilot valve part is connected with the liquid route intergraded socket of the corresponding pilot valve, an interface face of the main valve part on the main valve part is connected with the liquid route intergraded socket of the corresponding main valve, and the first connection between the plug and the liquid route intergraded socket which are arranged at the end part of the multi-core pipe realizes that each liquid inlet intersection and each liquid outlet intersection of thepilot valve part are communicated among each liquid intersection corresponding to the main valve part. The neighboring frame-operated pilot reversing valve not only can lead the pilot valve part to operate the main valve part by means of the neighboring frame, but also can lead the connection between the pilot valve part and the main valve part to be simple and fast.

Description

technical field [0001] The invention relates to a split-type pilot control valve, in particular to a multi-core pipe adjacent frame-operating pilot reversing valve for a coal mine hydraulic support. Background technique [0002] There are two basic ways to operate the coal mine fully mechanized hydraulic support: the operation of the main frame and the operation of the adjacent frame. The operation of this frame refers to: the operator is located at the position of the frame and operates the reversing valve handle located on the frame to complete various actions of the frame; the operation of the adjacent frame refers to: the operator is located at the position of the adjacent frame of the frame The pilot valve handle on the adjacent bracket controls the reversing action of the hydraulic control reversing valve on the bracket, thereby completing various actions of the bracket. The fundamental difference between the two is that the personnel are located under the active supp...
