Problems solved by technology

[0002] At present, when all kinds of general valves are selected for the powdery material medium with relatively harsh circulation conditions, due to the inherent factors of the valve core and valve cavity, such as gate valves, globe valves, check valves, butterfly valves, ball valves, etc., the valves have dead angles in the flow. Due to the frequent heat exchange of the valve during use, the circulating powdery material accumulates and hardens in the dead corner of the valve, which usually causes the blockage of the valve flow channel and the failure of the seal to open and close normally, which seriously affects the normal use of the valve.
In order to overcome the above difficulties, in the prior art, general-purpose valves have been unable to meet the requirements

Abstract

The invention relates to a wear resistant disc valve, belonging to the technical field of automatic control. The invention is characterized in that an adjustable shaft sleeve is arranged on a valve rod; the valve rod is inserted into the stuffing box of a right valve body; a valve seat is welded on the right valve body; the valve rod is provided with a key, a rocker, an adjusting gasket, and a bearing in sequence; a spring, a top core, and a valve clack are arranged on the rocker; a shaft sleeve is arranged on the left valve body; a sealing gasket, a valve body and the left valve body are arranged on the right valve body, and are fixed by bolts and nuts; a stuffing ring, stuffing, and a stuffing gland bush are arranged on the stuffing box in sequence, and the stuffing is compressed by bolts and nuts. The valve rod is provided with a handle and is fastened by the gasket and bolts. The wear resistant disc valve has simple structure and safe and reliable performance, is convenient for debugging and maintaining the valve when in use, has good sealability, and is capable of ensuring the normal running of the valve under the working condition on a high temperature high pressure pipeline.

Description

technical field [0001] The present invention relates to a wear-resistant disc valve, specifically a partial-rotation disc valve, which is widely used in electric power, coking, chemical industry, mining, polysilicon and other industries, and can adopt electric, pneumatic, intelligent adjustment and other operating systems, It belongs to the technical field of automatic control. Background technique [0002] At present, when all kinds of general valves are selected for the powdery material medium with relatively harsh circulation conditions, due to the inherent factors of the valve core and valve cavity, such as gate valves, globe valves, check valves, butterfly valves, ball valves, etc., the valves have dead angles in the flow. Due to the frequent heat exchange of the valve during use, the circulating powdery material accumulates and hardens in the dead corner of the valve, which usually causes blockage of the valve flow channel and the failure of the seal to open and close ...
