Abstract

The invention relates to a ball valve body structure. The ball valve body structure comprises a main valve body, a valve cover, a valve cover flange and a valve body flange. Inlet and outlet openings communicated with a valve cavity are formed in one side of the valve cover and one side of the valve cavity respectively; the valve cover is fixedly connected with the main valve body; valve seat shoulder steps for arranging a valve seat are disposed at the ends, close to the center of the valve cavity, of the inlet and outlet openings of the valve cover and the valve cavity; the valve cover flange and the valve body flange are provided with inlet and outlet channels respectively. Butt joint shoulder steps are only arranged on the outer wall of one end of the valve body flange and on the outer wall of one end of the valve cover flange, the end faces of both the valve cover flange and the valve body flange are flush with the annular planes of the valve seat shoulder steps, therefore the inlet and outlet channels in the main valve body and the valve cover are free of joints, and the joints are located on the annular planes of the valve seat shoulder steps; the teflon valve seat on the valve seat shoulder steps isolates a medium in a valve from the joints under the action of pressure, so that the possibility of leakage is eliminated; meanwhile, welding treatment for the joints is not needed, so that the process is simplified, and the production cost is reduced.

Description

A kind of ball valve body structure
Technical field
The present invention relates to a kind of valve body structure, a kind of ball valve body structure of specific design.
Background technique
Ball valve is owing to having the advantage of the light and long service life of wear-resisting, good seal performance, switch, and be widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, in national economy, occupy very important status.Ball valve is due to the reason of its structure, conveniently production and assembly, ball valve body is formed by a few incorporating aspects usually, generally comprise valve body body, valve gap, bonnet flange and valve flange, the valve pocket of accommodating spheroid is arranged in valve body body, described valve gap and valve body body are bolted and are limited in valve pocket by spheroid, bonnet flange is fixedly connected with valve gap, the side of valve gap and valve pocket is respectively equipped with import and export, described bonnet flange and valve flange are coordinated by internal and external threads and are connected with valve gap and valve body body respectively, valve pocket side and valve gap are provided with the valve seat shoulder rank for arranging valve seat near spheroid one end, described bonnet flange and valve flange are respectively equipped with access way.But due to existing ball valve body, valve flange and valve body body and bonnet flange are all take to be equipped with respectively to dock on inside and outside circle to take on rank with the Placement of valve gap, be threaded by the docking on docking shoulder rank again, therefore in the access way of described bonnet flange and valve flange, there is seam, physical contact between media in these seams and ball valve, in order to avoid revealing, butt joint is needed to weld during assembling, technique is loaded down with trivial details on the one hand, difficulty of processing is large, and welding quality has very high requirement, particularly high-pressure ball valve and be used in the ball valve of strong corrosive medium occasion, conforming product rate is low, cost of production is high.
Summary of the invention
The object of the invention is to provide a kind of without revealing to overcome the deficiencies in the prior art, simple process, difficulty of processing is little, the ball valve body structure that cost of production is low.
For achieving the above object, the invention discloses a kind of ball valve body structure, comprise valve body body, valve gap, bonnet flange and valve flange, the side of valve gap and valve pocket is respectively equipped with the import and export with valve pocket UNICOM, described valve gap is fixedly connected with valve body body, the import and export of valve gap and valve pocket are provided with the valve seat shoulder rank for arranging valve seat near the one end at valve pocket center, described bonnet flange and valve flange are respectively equipped with access way, it is characterized in that: one end that described valve flange is connected with valve body body and one end outer wall that bonnet flange is connected with valve gap are provided with to dock takes on rank, the internal diameter of the import and export on the import and export of described valve pocket and valve gap respectively with described valve flange and bonnet flange are docked the external diameter takeing on rank and match, the docking shoulder rank of described valve flange and bonnet flange are equipped with respectively in the import and export in the import and export and valve gap of described valve pocket, described valve flange is connected the end face of one end and bonnet flange be connected one end end face with valve gap and flushes with the planar annular that valve seat takes on rank with valve body body, described valve flange and valve body body and bonnet flange and the connecting sewing place of valve gap on cylindrical are fixedly connected by welding.
Ball valve body structure provided by the invention, one end outer wall be connected with valve gap by one end of being only connected with valve body body at described valve flange and bonnet flange is provided with to dock and takes on rank, and described bonnet flange and valve flange are connected one end end face with valve body body flushes with the planar annular that valve seat takes on rank, therefore not seam on the import and export passage in valve body body and valve gap, seam crossing is on the planar annular on valve seat shoulder rank, and the medium in valve and seam are isolated by tetrafluoro valve seat on valve seat shoulder rank under the effect of the pressure, stop the possibility revealed, seam crossing also need not carry out soldering simultaneously, simplify technique, difficulty of processing is little, reduce cost of production.
As the further setting of the present invention, the docking shoulder rank of described valve flange and bonnet flange are also provided with outside thread, also be provided with the internal thread matched with described outside thread in import and export on the import and export of described valve pocket and valve gap, described bonnet flange and valve flange are coordinated by internal and external threads and are connected with valve gap and valve body body respectively.More convenient like this assembling.
Below in conjunction with specific embodiment and accompanying drawing, the invention will be further described.
