Complete and safety of surrounding environment, therefore it is required that valve has extraordinary sealing property and decay resistance, avoids hazardous medium from sending out
Raw leakage.And ball valve of the prior art can not reach above-mentioned requirements.
Utility model content
The purpose of this utility model is to provide a kind of strong corrosion resistant ball valve with preferable sealing property, ensures that deep-etching is situated between
The safe transport of matter.
Realizing the technical scheme of above-mentioned purpose is：Strong corrosion resistant ball valve, including valve body, valve rod, valve ball, handle, in valve body
Be provided with the passage passed through for transmission medium, axis hole be provided with valve body, valve ball is installed in valve body, the lower end of the valve rod with
Valve ball connection, upper end are upward through the axis hole and are connected with handle, and valve seat is respectively arranged with the valve body of the valve ball both sides, its
It is characterised by：Anticorrosive coat, the valve seat of the both sides are respectively arranged with the flow of media passage of the valve body, valve seat and valve ball
The annular groove of closing is provided between valve body, spring is correspondingly arranged in annular groove.
Further, it is respectively arranged with sealing ring between the outer end of the valve seat and valve body.
Further, it is provided with the annular chamber of upper end open between the valve body and valve rod, it is circumferentially arranged on valve rod to have
Annular chamber is divided into lower annular seal space and upper annular seal space, tetrafluoro is provided with the lower annular seal space by one annular protrusion, annular protrusion
Pad, filler is provided with the upper annular seal space and is compressed by gland.
Further, annular groove is circumferentially offered on the annular protrusion, O shapes are set with the annular groove
Sealing ring.
Further, screen pack is provided with the entrance point of the valve body, the impurity in medium can be filtered out, avoided pair
The sealing surface of valve seat and valve ball causes to damage.
Further, the anticorrosive coat uses polytetrafluoroethylmaterial material.
The beneficial effects of the utility model：
1st, anticorrosive coat is respectively arranged with the flow of media passage of valve body, valve seat and valve ball, anticorrosive coat uses polytetrafluoro
Vinyl material, polytetrafluoroethylmaterial material have antiacid alkali resistant, resist the characteristics of various organic solvents, are practically insoluble in all molten
Agent, meanwhile, polytetrafluoroethylene (PTFE) has resistant to elevated temperatures feature, avoids medium channel from corroding, and causes to leak.
2nd, the annular groove of closing is provided between the valve seat and valve body of the utility model both sides, is correspondingly arranged in annular groove
Spring, it is close to by the sealing surface of the valve seat of spring both sides on the sphere of valve ball, avoids leaking.
The 3rd, annular chamber is set in the upper end open of axis hole, it is close to be disposed with Tetrafluoro spacer, O shapes from bottom to top in annular chamber
Seal and filler, ensure the reliable sealing between valve body and valve rod.
