Abstract
The utility model relates to a silicon carbide ceramic ball valve. The utility model is mainly characterized in that the lower end of a valve rod is sheathed with a ceramic shaft sleeve, the lower end of the ceramic shaft sleeve is connected with a ceramic valve ball, the lower part of the ceramic valve ball is provided with a ceramic supporting shaft, and the inner part of a valve body is sheathed with a ceramic outer lining and a ceramic inner lining. The utility model provides an innovative design for a valve structure and a processing technology, and silicon carbide ceramic materials can be used as a sealing member and an anticorrosive lining material for an industrial valve. The utility model can be used for various medium pipeline systems of a corrosive gas pipeline system, a liquid pipeline system, a hard particle pipeline system, etc. The utility model has the good characteristics of corrosion resistance, high temperature resistance, wear resistance, washing resistance, etc. The service life of the sealing member of the utility model can reach more than six times of the service life of the departmental standard.
Description
The utility model relates to a kind of silicon carbide ball valve.
Valve is the requisite important operational outfit of industrial production pipe-line system, but still exists corrosion-resistant poorly so far at widely used metal valve, and strong hardness is low, and high temperature is yielding, causes seal leakage, not anti-wash away easy to wear, defective such as working life is short.
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the silicon carbide ceramics ball valve of long service life.
The technical solution of the utility model is as follows: it is mainly by valve rod, valve body and valve ball three parts constitute, valve body is divided into a stage casing valve body and a left side, right valve barrel, it is characterized in that: be with a Ceramic shaft sleeve in the lower end of valve rod, the below of Ceramic shaft sleeve is connected with ceramic valve ball, the ceramic supporting axle is equipped with in the below of pottery valve ball, two ends at ceramic valve ball are provided with a left side, right valve barrel, the pottery valve ball is positioned at the stage casing body cavity, in the valve body of the left and right sides, be with the ceramic-lined cover of the ceramic external bushing and the T shape left and right sides about the T type respectively, in neck bush, be with valve seat, between valve seat and external bushing, be provided with belleville spring.
The utility model proposes innovative design to valve mechanism and processing technology, thyrite is applied in makes Sealing and antisepticise lining material on the industrial valve.The utility model product can be widely used in the pipe-line system of media such as all kinds of corrosive gass, liquid, grit, has corrosion-resistant, high temperature resistant, wear-resistant, anti-good characteristic such as wash away, and its seal life reaches ministry standard more than six times.
Fig. 1 is the utility model structural representation
In order to make the utility model structure clear more complete, be described further below in conjunction with accompanying drawing.
As shown in the figure: the utility model mainly is made of valve rod 1, valve body and valve ball 2 three parts, valve body is made of stage casing valve body 3 and left and right valve body 4,5, be with Ceramic shaft sleeve 6 in the lower end of valve rod 1, the below of Ceramic shaft sleeve 6 is contained in the groove of opening ceramic valve ball 2 tops, ceramic supporting axle 7 is equipped with in the below of pottery valve ball 2, and ceramic valve ball 2 is play supporting role.Be provided with left and right valve body 4,5 at the two ends of ceramic valve ball 2, pottery valve ball 2 is positioned at the inner chamber of stage casing valve body 3, in left and right sides valve body 4,5, be with T shape pottery external bushing 8 and the ceramic-lined cover 9 of T shape, in neck bush 9, be with valve seat 10, on valve seat 10, have seal groove, in seal groove, adorning sealing damping device 13,10 formation of neck bush 9 and valve seat are tightly connected, be provided with belleville spring 11 at valve seat 10 and 8 of external bushings, be provided with sealing layer 12 at stage casing valve body 3 and 2 of ceramic valve balls.
