Abstract

The invention discloses a cone stove valve and relates to the technical field of mining valves. The cone stop valve comprises a valve body, a valve rod, a valve bushing, a barrel, a hand wheel and a valve rod bushing, wherein the valve bushing is arranged in the valve body and sleeves the valve rod, and a first balance cavity for allowing liquid to flow into is formed between the valve bushing andthe valve rod; the barrel is connected with the valve body and sleeves the valve rod; the valve rod bushing is arranged inside the barrel and sleeves the valve rod, and a second balance cavity for allowing the liquid to flow into is reserved between the barrel and the valve rod bushing; the valve rod is provided with a damping channel for allowing the liquid to flow into and enabling the first balance cavity and the second cavity to communicate with each other; and the hand wheel is connected with the valve rod. Through arrangement of the first balance cavity and the second balance cavity, resistance generated when the hand wheel is screwed in the opening or closing process of the cone stop valve is greatly reduced, operation torque can be reduced so that labor for operation can be saved,and meanwhile, by means of a dust hood, complicated conditions under a mine are isolated and the situation that the hand wheel is exposed in the severe condition and contaminated to result in the rusting risk is prevented.

Description

technical field [0001] The invention belongs to the technical field of mine valves, in particular to a cone stop valve. Background technique [0002] The cone stop valve is a kind of stop valve, which is widely used in the hydraulic circuit of the hydraulic support of the coal mine fully mechanized mining face. Usually, the valve stem of the cone globe valve is connected to the valve core through a screw sleeve. This connection method has a complex structure, troublesome assembly process, low production efficiency, and large torque during operation, which is laborious. Contents of the invention [0003] Based on the above deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a cone stop valve to solve all or one of the problems mentioned in the background technology. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A conical ...
