Abstract
The utility model discloses a ceramic coated seal plug valve which comprises a valve body, wherein the valve body is provided with a medium inlet section and a medium outlet section, and a valve core hole is arranged between the medium inlet section and the medium outlet section of the valve body. A valve core which is matched with the valve core hole is arranged in the valve core hole. One end of the valve core passes out of the valve body and is sealed with the valve body. The valve body is provided with an end cover. The valve core and the valve core hole present the shape of a truncated cone with a forward direction. The surface of the valve core is coated with a ceramic layer, and the valve core is provided with a control hole. The plug valve adopts the direct match of the valve body and the valve core to control the medium. The matching surface of the valve core is coated with ceramics. On one hand, the shape of the matching surface can be ensured, and on the other hand, the matching surface is ensured to have longer service life. After a compensation device is arranged, matched automatic compensation of the valve core and the valve core hole can be realized. The utility model has the advantages of stronger anti-scour ability and longer service life and is suitable for working conditions, such as powder media, dangerous media, corrosion media, high-temperature environment, etc.
Description
Technical field
The utility model belongs to the valve of pipeline medium control usefulness, is specifically related to a kind of ceramic coated sealing stopcock.
Technical background
The sealing material of present traditional plug valve is teflon or rubber, and this sealing configuration is easily aging, and the life-span is short, does not possess corrosion resistance, non-refractory.
Summary of the invention
The purpose of this utility model is to provide a kind of ceramic coated sealing stopcock with ceramic coated, to solve the defective of above-mentioned stopcock.
The technical solution of the utility model is: ceramic coated sealing stopcock, comprise valve body, establish medium inducer, media outlet section on the valve body, establish spool bore between the medium inducer of valve body, the media outlet section, establish the spool that cooperates with it in the spool bore, spool one end passes valve body and sealing with it, establish end cap on the valve body, spool and spool bore are the forward circular cone shape, and spool face coated ceramic layer leaves control hole on the spool.
Also automatic compensator can be set in this valve.This plug valve adopts the direct cooperation of valve body and spool to come control media, and the fitting surface coated ceramic of spool can guarantee the fitting surface shape on the one hand, guarantees that on the other hand fitting surface had than the long-life.After compensation device is set, can realize the automatic compensation of spool and spool bore surface engagement, stronger anti-impact erosion ability is arranged, have the longer life-span, adapt to operating conditions such as powder medium, danger medium, aggressive medium, hot environment.
