Problems solved by technology

The cost of manual reversing valve is low, but the production efficiency is low, and there are defects such as potential safety hazards
The electro-hydraulic reversing valve can realize automatic mining of coal mines and improve production efficiency, but the cost is high
At present, most coal mines in my country use manual reversing valves. If they are directly replaced with electro-hydraulic reversing valves, they need to invest a lot of money to purchase new reversing valves.

Embodiment Construction

[0026] It should be noted that the embodiments of the present invention and the features of the embodiments may be combined with each other under the condition of no conflict.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0028] like figure 1 As shown, the manual reversing valve is modified by the method of the present invention, and the remodeled manual reversing valve includes three parts: a manual reversing valve body 1 , a conversion insert 2 and an operating handle 3 . Among them, the manual reversing valve body 1 and the operating handle 3 are the two components of the original manual reversing valve on the hydraulic support, and the conversion insert 2 is the core component of the new design of this project.

[0029] like figure 2 As shown, the conversion plug-in 2 includes a liquid distribution plate 4, a valve body 5 and a conversion plate 6 which are installed...

Abstract

The invention provides an automation reforming method for a hand-operated reversing valve. The structure of the hand-operated reversing valve is not changed, a handle of the hand-operated reversing valve is disassembled from a hydraulic valve body, a manual-automatic change-over insertion piece is installed between the handle and the hydraulic valve body, the manual-automatic change-over insertion piece is in butt joint with the handle of the hand-operated reversing valve through a change-over plate and is connected with the hydraulic valve body of the hand-operated reversing valve through a liquid distributing disc for control, and a driving valve body is arranged between the change-over plate and the liquid distributing disc. According to the automation reforming method for the hand-operated reversing valve, based on the original hand-operated reversing valve of a hydraulic support, the hand-operated reversing valve is subjected to automation reforming, cost is saved, the production effect can be improved, and potential safety hazards can be avoided; the automation reforming method has the advantages that the structure is simple, and installing and reforming are convenient.

Description

technical field [0001] The invention belongs to the field of mining hydraulic supports, and particularly relates to an automatic transformation method of a manual reversing valve. Background technique [0002] Hydraulic support is a main working face equipment for longwall mining in coal mines, and its adaptability and reliability are one of the key factors for safe and efficient production of working faces. The existing hydraulic supports mainly use two types of reversing valves, including manual reversing valves and electro-hydraulic control reversing valves. The cost of manual reversing valve is low, but the production efficiency is low, and there are defects such as potential safety hazards. Electro-hydraulic reversing valve can realize automatic coal mining and improve production efficiency, but the cost is high. At present, most coal mines in my country use manual reversing valves. If they are directly replaced with electro-hydraulic reversing valves, a lot of money ...
