Abstract
The utility model is related to a kind of ball valve body.Including valve body body, bonnet, bonnet flange and valve flange, the bonnet flange and valve flange are flat annulus shape component, the inlet part of the valve body body and bonnet is cylindrical, the entrance point of the valve body body and bonnet is equipped with external screw thread, the valve flange and the endoporus of bonnet flange are respectively equipped with the internal thread that external screw thread matches on the entrance point with the valve body body and bonnet, and the bonnet flange and valve flange are coordinated by internal and external threads to be connected with bonnet and valve body body respectively.Therefore not seam on the import and export passage in valve body body and bonnet, seam is only on the entrance point of valve body body and bonnet obtains end face and be cylindrical, the possibility of leakage is prevented, extend service life, soldering need not be also carried out in access opening simultaneously, technique is simplified, difficulty of processing is small, reduces production cost.
Description
Technical field
The utility model is related to a kind of valve body structure, a kind of ball valve body of specific design.
Background technology
Ball valve is widely used due to having the advantages that wear-resisting, good seal performance, switch are light and service life is long
The industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, steel, occupy act in national economy
The status of sufficient weight.Ball valve is due to its structure, production and assembly for convenience, ball valve body generally combined by several parts and
Into generally comprising valve body body, bonnet, bonnet flange and valve flange, the valve pocket of accommodating spheroid is arranged in valve body body, institute
State bonnet and valve body body and be bolted and spheroid is limited in valve pocket, bonnet flange is fixedly connected with bonnet, bonnet and
The side of valve pocket is respectively equipped with import and export, the bonnet flange and valve flange by internal and external threads coordinate respectively with bonnet and valve
Body body is connected, and valve pocket side and bonnet are provided with the valve seat shoulder rank for being used for setting valve seat, the bonnet flange close to spheroid one end
And valve flange is respectively equipped with access way.But it is due to existing ball valve body, valve flange and valve body body and bonnet method
Orchid is all to take to be equipped with inside and outside circle respectively to dock shoulder rank with the connected mode of bonnet, then by docking the docking spiral shell of shoulder rank
Line is connected, therefore there is seam in the access way of the bonnet flange and valve flange, these seams and Jie in ball valve
Upright contact, shortens product service life, in order to avoid leakage, needs abutment joint to be welded during assembling, one side work
Skill is cumbersome, and difficulty of processing is big, and welding quality has very high requirement, particularly high-pressure ball valve and used in strong corrosive medium
The ball valve of conjunction, product qualification rate is low, and production cost is high.
The content of the invention
The purpose of this utility model is to provide seamless in a kind of access way to overcome the deficiencies in the prior art,
The longer ball valve body of simple processing, service life.
To reach above-mentioned purpose, the utility model discloses a kind of ball valve body, including valve body body, bonnet, bonnet method
The side of blue and valve flange, bonnet and valve pocket is respectively equipped with the import and export with valve pocket UNICOM, and the bonnet is consolidated with valve body body
Fixed connection, it is characterised in that：The bonnet flange and valve flange are flat annulus shape component, the valve body body and bonnet
Inlet part is cylindrical, and the entrance point of the valve body body and bonnet is equipped with external screw thread, valve flange and the bonnet method
Blue endoporus is respectively equipped with the internal thread that external screw thread matches on the entrance point with the valve body body and bonnet, the bonnet flange
And valve flange is connected with bonnet and valve body body respectively by internal and external threads cooperation.
The ball valve body that the utility model is provided, by being equipped with outer spiral shell in the entrance point of the valve body body and bonnet
The endoporus of line, the valve flange and bonnet flange is respectively equipped with external screw thread phase on the entrance point with the valve body body and bonnet
The internal thread matched somebody with somebody, the bonnet flange and valve flange are coordinated by internal and external threads to be connected with bonnet and valve body body respectively, because
Not seam on import and export passage in this valve body body and bonnet, seam must only be held in the entrance point of valve body body and bonnet
Face and it is cylindrical on, prevented the possibility of leakage, extended service life, while need not also carry out soldering in access opening,
Technique is simplified, difficulty of processing is small, reduces production cost.
As further setting of the present utility model, the inlet part of the valve body body and bonnet is provided with shoulder rank, shoulder rank
The length of section is adapted with the thickness of the valve flange and bonnet flange, and the external screw thread is arranged on shoulder rank.It is so both beautiful
See again more convenient assembling.
The utility model is further described below in conjunction with specific embodiment and accompanying drawing.
Brief description of the drawings
Fig. 1 is the utility model specific embodiment structure sectional view.
