Technical Field
The invention relates to a ball valve, in particular to a fixed ball valve.
Background
A ball valve is a valve in which a valve stem drives a valve ball to rotate and to rotate about the axis of the ball valve. The ball valve is including valve body, valve ball, valve rod and disk seat, as shown in fig. 3, the disk seat of general current ball valve also is formed by left valve body and right valve body are connected, and the face of only both installations is the perpendicular, and this kind of structure is fit for valve ball and the split type structure of valve rod, and to valve ball and valve rod integral type structure, just can't install in this kind of valve body. However, in the case of a small-diameter fixed ball valve, since the ball is small, it is necessary to open a groove for connecting a valve stem on the upper surface in addition to the flow hole on the upper surface, which is difficult to achieve in the art, even if it is achieved that the ball is easily damaged since the base surface of the groove is too small. Therefore, the best mode is that the valve ball and the valve rod are integrally formed, but after the valve ball and the valve rod are integrally formed, the existing common valve structure cannot be normally installed.

In view of the defects in the prior art, the invention innovatively provides the inclined-surface middle-flange small-caliber fixed ball valve which is suitable for integrally forming and mounting the valve ball and the valve rod.
The fixed ball valve of flange small-bore in this kind of inclined plane, including valve body, valve rod, disk seat, valve ball and fixed axle, its characterized in that: the valve body is formed by left valve body and right valve body through the bolt equipment, left side valve body has left installation inclined plane, right valve body has right installation inclined plane, the left installation inclined plane of left side valve body is laminated mutually with the right installation inclined plane of right valve body, the valve rod is located left valve body, the fixed axle is located right valve body, the valve ball is located between left valve body and the right valve body, equal threaded connection has the regulation seat on left side valve body and the right valve body, the disk seat is located between valve ball and the regulation seat, adjust the seat and can act on the disk seat, the recess that supplies the instrument to get into has on the regulation seat.
The valve body and the valve rod are integrally formed.
The right mounting inclined plane of the right valve body is provided with a positioning protrusion, the left mounting inclined plane of the left valve body is provided with a positioning groove, and the positioning protrusion is arranged in the positioning groove in a matched mode.
And a disc spring is arranged between the adjusting seat and the valve seat.
And an O-shaped sealing ring is arranged on the valve seat and acts on the valve body.
And a flexible graphite packing is arranged on the valve seat.
According to the slope middle flange small-caliber fixed ball valve provided by the invention, the left valve body and the right valve body are installed through the slopes, so that the integrally formed valve ball and the valve rod are also installed.

Detailed Description
As shown in fig. 1 and 2, the flange small-caliber fixed ball valve in the inclined plane comprises a valve body, a valve rod 4, a valve seat 5, a valve ball 3 and a fixed shaft 7, wherein the valve body is formed by assembling a left valve body 1 and a right valve body 2 through a bolt 8, the left valve body 1 is provided with a left installation inclined plane, the right valve body 2 is provided with a right installation inclined plane, the left installation inclined plane of the left valve body 1 is attached to the right installation inclined plane of the right valve body 2, the valve rod 4 is positioned on the left valve body 1, the fixed shaft 7 is positioned on the right valve body 2, the valve ball 3 is positioned between the left valve body 1 and the right valve body 2, the left valve body 1 and the right valve body 2 are respectively in threaded connection with an adjusting seat 6, the valve seat 5 is positioned between the valve ball 3 and the adjusting seat 6, the adjusting seat 6 can.
During the installation, because left valve body 1 has left installation inclined plane, just so can be with valve rod 4 from up passing left valve body 1 down, and valve rod 4 integrated into one piece's valve ball 3 is just close to disk seat 5 on the left valve body 1, later with the right installation inclined plane of right valve body 2 and the left installation inclined plane laminating of left valve body 1, then fix both with a plurality of bolts 8, the back is installed to the valve body, two disk seats 5 on left valve body 1 and the right valve body 2 all are close to valve ball 3, get into the recess 60 of adjusting seat 6 through the instrument after that, and rotate adjusting seat 6, because adjusting seat 6 is threaded connection, adjusting seat 6 just so and pushing away disk seat 5 and moving to the inboard, and order about disk seat 5 and act on valve ball 3, just so accomplish the installation.
The valve body adopts an inclined plane split structure and is suitable for installation of an integrated structure of the valve body and the valve rod 4. Of course, the valve body and the valve rod 4 can be mounted in a separate structure.
In order to facilitate the combination of the left valve body 1 and the right valve body 2, the positioning protrusion is arranged on the right mounting inclined surface of the right valve body 2, the positioning groove is arranged on the left mounting inclined surface of the left valve body 1, when the left valve body 1 and the right valve body 2 are combined, the positioning can be completed only by arranging the positioning protrusion in the positioning groove in a matching manner, and then the bolt 8 is screwed.
In order to provide the valve seat 5 with a certain elasticity, the invention is provided with a disc spring 9 between the adjusting seat 6 and the valve seat 5. The disc spring 9 enables a certain floating effect of the valve seat 5 and thus a good sealing effect with the valve ball 3.
In order to form a seal between the valve seat 5 and the valve body, an O-ring 10 is provided on the valve seat 5, and the O-ring 10 acts on the valve body.
In order to form a better sealing effect between the valve seat 5 and the valve body, the valve seat 5 is provided with a flexible graphite packing 11, and the flexible graphite packing 11 can enable the ball valve to realize good position sealing under high temperature and high pressure.
