Abstract
A kind of corrosion preventive ball-valve stuffing box structure, described metal valve body inner chamber is provided with ceramic-lined; It is ceramic-lined that valve body stuffing box hole is provided with stuffing box; Valve rod be arranged on stuffing box ceramic-lined in; Corrosion resistance filler is had between the ceramic-lined and valve rod of stuffing box; Corrosion resistance filler is pressed in stuffing box by Gland; Mounting O-shaped rings between the ceramic-lined and valve body of stuffing box is ceramic-lined, forms sealing by compressing metal crimp dish.The utility model has the advantages that: metal valve body inner chamber and stuffing box hole are installed ceramic-lined, and two ceramic-lined joints realize sealing by mounting O-shaped rings, prevent strong corrosive media to the corrosion of metal valve body; At stuffing box, between ceramic-lined and valve rod, corrosion resistance filler is set, ensure valve rod and stuffing box ceramic-lined between sealing, when there being medium to leak from Gland, Gland can being compressed by the bolt tightened on Gland, reaching packing seal.
Description
Technical field
The utility model belongs to stuffing box structure, particularly a kind of corrosion preventive ball-valve stuffing box structure.
Background technique
Ball valve widely uses in each industrial system such as oil, chemical industry, the features such as ball valve has good seal performance, long service life.But when ball valve is applied in the strong system of corrosivity, because valve body cannot stand the corrosion of medium, stuffing box position often has medium and reveals generation, drastically influence valve and normally runs, also can cause the pollution of environment.
Summary of the invention
For the technical problem of above-mentioned existence, the purpose of this utility model proposes a kind of corrosion preventive ball-valve stuffing box structure, prevents strong corrosive media to the corrosion of metal valve body.
Technical solution of the present utility model is achieved in that a kind of corrosion preventive ball-valve stuffing box structure, it is characterized in that: comprise metal valve body, valve body is ceramic-lined, stuffing box is ceramic-lined, metal platen, valve rod, Gland and O type circle, described metal valve body inner chamber is provided with ceramic-lined; It is ceramic-lined that described valve body stuffing box hole is provided with stuffing box; Described valve rod be arranged on stuffing box ceramic-lined in; Corrosion resistance filler is had between the ceramic-lined and valve rod of described stuffing box; Described corrosion resistance filler is pressed in stuffing box by Gland; Mounting O-shaped rings between the ceramic-lined and valve body of described stuffing box is ceramic-lined, forms sealing by compressing metal crimp dish.
The utility model compared with prior art has following advantages:
1, install ceramic-lined by body cavity and stuffing box hole, and two ceramic-lined joints realize sealing by mounting O-shaped rings, prevent strong corrosive media to the corrosion of metal valve body;
2, by arranging corrosion resistance filler between and valve rod ceramic-lined at stuffing box, ensure the sealing between valve rod and stuffing box, when there being medium to leak from Gland, Gland can being compressed by the bolt tightened on Gland, reaching packing seal.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is structural representation of the present utility model;
Wherein: 1-valve body is ceramic-lined; 2-metal valve body; 3-O type circle; 4-stuffing box is ceramic-lined; 5-corrosion resistance filler; 6-Gland; 7-valve rod; 8-bolt; 9-metal platen.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described.
Accompanying drawing 1 is a kind of corrosion preventive ball-valve stuffing box structure described in the utility model, comprise that metal valve body 2, valve body are ceramic-lined 1, stuffing box be ceramic-lined 4, metal platen 9, valve rod 7, Gland 6 and O type circle 3, described metal valve body 2 inner chamber is provided with valve body ceramic-lined 1; Described valve body 2 stuffing box hole is provided with stuffing box ceramic-lined 4; Described valve rod 7 is arranged in stuffing box ceramic-lined 4; Corrosion resistance filler 5 is had between described stuffing box ceramic-lined 4 and valve rod 7; Described corrosion resistance filler 5 is pressed in stuffing box ceramic-lined 4 by Gland 6; Mounting O-shaped rings 3 between described stuffing box ceramic-lined 4 and valve body ceramic-lined 1, is compressed by metal platen 9 and forms sealing; The utility model is installed ceramic-lined by metal valve body 2 inner chamber and stuffing box hole, and two ceramic-lined joints realize sealing by mounting O-shaped rings 3, and strong corrosive media can be prevented the corrosion of metal valve body 2; By arranging corrosion resistance filler 5 between stuffing box ceramic-lined 4 and valve rod 7, ensure the sealing between valve rod 7 and stuffing box ceramic-lined 4, when there being medium to leak from Gland 6, Gland 6 can be compressed by the bolt 8 tightened on Gland 6, reach corrosion resistance filler 5 and seal.
