Description
Technical Field
The utility model relates to a ball valve, concretely relates to 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.
Disclosure of Invention
In view of the deficiencies in the prior art, the utility model discloses the innovation provides a flange minor-caliber fixed ball valve in the inclined plane that is suitable for valve ball and valve rod integrated into one piece installation.
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, the regulation seat can act on the disk 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 utility model provides a pair of fixed ball valve of flange minor bore in inclined plane, because left valve body passes through the inclined plane installation with right valve body, integrated into one piece's valve ball also realizes the installation with the valve rod like this.
