Full-lining ceramic wheel valve

Abstract

The invention discloses a full-lining ceramic wheel valve. The full-lining ceramic wheel valve comprises a valve element, a valve seat, an upper flange lining, a lower flange lining, a driving ring, avalve rod, an upper flange, a valve body and a lower flange, the upper flange and the lower flange are fixed to the upper end and the lower end of the valve body through connecting pieces correspondingly, the center lines of the upper flange, the lower flange and the valve body are located on the same straight line, the upper flange lining is mounted in the upper flange, the lower flange lining is mounted in the lower flange, the valve element, the valve seat, the driving ring and the valve rod are mounted in a valve cavity composed of the upper flange lining, the lower flange lining and thevalve body, the valve seat is fixed into the lower flange and mounted on the lower flange lining, a protruding shaft is arranged in the center of the valve seat, the valve element is fixed into a circular ring of the driving ring, the center of the valve element is mounted on the protruding shaft, a plurality of flow holes in the circumferential direction of the valve element and the valve seat are formed in the valve element and the valve seat, at least one end of the valve rod penetrates through the valve body, the center line of the valve rod is perpendicular to the center line of the valveelement and the center line of the driving ring, and the valve rod drives the valve element and the driving ring to rotate around the protruding shaft, so that the flow holes in the valve element andthe flow holes in the valve seat are aligned or staggered mutually.

Description

technical field [0001] The invention relates to a ceramic valve, in particular to a fully lined ceramic wheel valve. Background technique [0002] At present, in some chemical industry working conditions, the medium used has many of the characteristics of easy accumulation, high toughness, difficult to cut, strong corrosion, and strong erosion, such as gate valves, ball valves, disc valves, globe valves, etc. The valves of various forms are still reluctant to deal with one of the characteristics. If the medium has multiple characteristics at the same time, the above-mentioned types of valves are even more powerless, and it is difficult to meet the needs of this multi-characteristic medium for the valve. [0003] Under such working conditions, a valve that can meet the requirements of various stringent characteristics of the medium is required. Contents of the invention [0004] The purpose of the invention of this application is to overcome the disadvantages of easy accum...
