Problems solved by technology

Because the valve body is a special-shaped casting structure, it needs to be processed separately. The whole valve structure is complicated, the processing is cumbersome, the volume is large, and the quality is heavy. Due to the defects of the special-shaped casting itself, the strength of the valve body is not high. It takes up a lot of space, the labor intensity of the staff is too high during installation and maintenance, and it is inconvenient to install and disassemble

Abstract

The invention relates to a pneumatic abrasion-resisting angle stop valve which is small in size, light in weight, flexible to open, good in seal performance, resistant to abrasion and impact, easy to install, low in production cost and suitable for cutting off dust and ash dregs. The pneumatic abrasion-resisting angle stop valve comprises a valve body, a valve body sleeve, a valve base, a valve cover and a valve body neck bush, a valve rod, a valve clack sleeve and a valve clack are installed in the valve body, and a packing pad and a packing ring are arranged between the upper portion of the valve cover and the valve rod from bottom to top. The pneumatic abrasion-resisting angle stop valve is characterized in that a screw hole is formed in the valve cover, a round nut used for clamping a pneumatic device is installed at the upper end of the valve rod, the valve clack and the valve base are made of tungsten and cobalt hard alloy, the sealing face of the valve base and the valve clack is a conical face, the valve clack sleeve and the valve clack are connected through a spherical surface antifriction bearing, the lower end of the valve rod and the valve clack sleeve are connected in a conical face mode to achieve automatic centering, the lower end face of the valve rod is a spherical surface and makes contact with the upper end face of the valve clack for automatic center adjustment, and a lower end opening of a center through hole of the valve cover is a conical face to form an upper sealing point.

Description

technical field [0001] The invention relates to a stop valve, in particular to a pneumatic wear-resistant angle stop valve. Background technique [0002] The traditional angle globe valve is composed of valve body, bonnet, valve stem, valve core, valve disc, bracket, manual or driving device connected to the upper part of the valve stem. Because the valve body is a special-shaped casting structure, it needs to be processed separately. The whole valve structure is complicated, the processing is cumbersome, the volume is large, and the quality is heavy. Due to the defects of the special-shaped casting itself, the strength of the valve body is not high. It takes up a lot of space, and the labor intensity of the staff during installation and maintenance is too large, and it is inconvenient to install and disassemble. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art, and provide a small volume, li...
