Mechanical integrated six-position slide valve and application method

Abstract

The invention discloses a mechanical integrated six-position slide valve and an application method. The mechanical integrated six-position slide valve comprises an integrated valve body, the valve body comprises two valve chambers, each valve chamber is provided with a water inlet, a water outlet, an air inlet and an air outlet, and a valve element which can slide between the first position and the second position is arranged in each valve chamber; the first position is used for blocking circulation between the water inlets and the water outlets and circulation between the air inlets and the air outlets at the same time, the second position is used for allowing circulation between the water inlets and the water outlets and circulation between the air inlets and the air outlets at the sametime, a control port is further formed in each valve chamber, and a spring is further arranged in each valve chamber. The mechanical integrated six-position slide valve has the advantages that the aimof automation of a spray and dust reduction device is achieved, the environment of a working face is improved, the hazard of occupational diseases is reduced, the production efficiency is improved, the working intensity of workers is reduced, automation can be achieved without any power supply, and the safety degree is high.

Description

technical field [0001] The invention relates to the technical field of slide valves, in particular to a mechanical integrated six-position slide valve and a use method thereof. Background technique [0002] At present, the main sources of dust in the fully mechanized mining face of the coal mine are coal mining by the shearer, the dust produced by caving coal (if any), and the dust produced by the lowering and moving of the frame. The existing dust reduction technologies mainly include internal and external spraying of the shearer, support Spraying, where the support spray is sprayed when the hydraulic support is lowered and moved. The existing spray dust suppression device for support spray generally adopts the spray dust control form of water and air two-way control. In the spraying process, manual or electric Control, manual control is adopted, automation cannot be realized, and the work intensity of workers is high, and electric control is adopted, which is prone to elec...

[0002] At present, the main sources of dust in the fully mechanized mining face of the coal mine are coal mining by the shearer, the dust produced by caving the top coal (if any), and the dust produced by the lowering and moving of the frame. Spraying, where the support spray is sprayed when the hydraulic support is lowered and moved. The existing spray dust suppression device for support spray generally adopts the spray dust control form of water and air two-way control. In the spraying process, manual or electric Control, manual control is adopted, automation cannot be realized, and the work intensity of workers is high, and electric control is adopted, which is prone to electric shock risk
