The supporting component comprises a supporting rod, a sealing hole is formed in the lower end of the first valve body, the supporting rod penetrates through the sealing hole and supports the lower end of the valve ball, and the valve ball can freely rotate on the supporting rod.
The lower end of the valve ball is provided with a positioning hole, a supporting ball is arranged in the positioning hole, the upper end of the supporting rod is provided with a semicircular supporting groove, and the supporting ball is rotatably arranged between the supporting groove and the bottom surface of the positioning hole.
Pipe threads are arranged in the sealing holes, and the supporting rod is in threaded connection with the pipe threads.
The lower end of the supporting rod is fixedly connected with a nut, and a plurality of bayonets are formed in the nut;
the lower end of the first valve body is screwed with a positioning pin, and the positioning pin is inserted in the bayonet.
The lower wall surface of the first flow channel is provided with a limiting hole, a limiting ball is arranged in the limiting hole, and the limiting ball is rotatably arranged between the limiting hole and the outer wall surface of the valve ball.
Through adopting above-mentioned technical scheme, support at the bracing piece of valve ball lower extreme through rotating to make the bracing piece drive the ball valve and reciprocate, with the installation clearance when the adjustment is installed, and guaranteed that whole ball valve has better sealed effect.
Has the advantages that: the adoption is with valve ball upper end fixed connection on the valve rod, and the lower extreme rotates and sets up on the bracing piece to adjust the position of valve ball through the bracing piece, with the installation that realizes that the valve ball can be better in the runner of valve body.

Detailed Description
As shown in fig. 1 and 2, a ball valve is provided, which includes a first valve body 1 and a valve rod 2, wherein the valve rod 2 is rotatably disposed at an upper end of the first valve body 1, a first flow passage is formed in the first valve body 1, a valve ball 3 is rotatably disposed in the flow passage, and an upper end of the valve ball 3 is fixedly connected with a lower end of the valve rod 2; the lower extreme of first valve body 1 is equipped with the supporting component who is used for supporting valve ball 3, and supporting component lower extreme fixed connection is on first valve body 1, and the lower extreme at valve ball 3 is supported to the upper end of supporting component, and valve ball 3 can be on the supporting component free rotation. The supporting component comprises a supporting rod 4, a sealing hole is formed in the lower end of the first valve body 1, the supporting rod 4 penetrates through the sealing hole and supports the lower end of the valve ball 3, and the valve ball 3 can freely rotate on the supporting rod 4. The lower extreme of valve ball 3 has seted up the locating hole, is provided with support ball 5 in the locating hole, and the semicircular bracket is seted up to the upper end of bracing piece 4, and support ball 5 rotates and sets up between the bottom surface of holding in the palm the groove and locating hole. The sealing hole is internally provided with pipe threads, and the support rod 4 is screwed in the pipe threads. Through rotating bracing piece 4 of spiro union in the pipe thread to the position of adjustment valve ball 3, thereby reach the effect of installing in first runner that valve ball 3 can be better.
In order to prevent the support rod 4 from rotating after the position is adjusted, the lower end of the support rod 4 is fixedly connected with a nut 6, and the nut 6 is provided with a plurality of bayonets; the lower end of the first valve body 1 is screwed with a positioning pin 7, and the positioning pin 7 is inserted in the bayonet. A limiting hole is formed in the lower wall surface of the first flow channel, a limiting ball 8 is arranged in the limiting hole, and the limiting ball 8 is rotatably arranged between the limiting hole and the outer wall surface of the valve ball 3. During installation, the valve ball 3 can be positioned through the limiting ball 8, and when the valve ball 3 is rotated, the limiting ball 8 plays a supporting role to prevent the valve ball 3 from moving downwards due to positioning deviation after multiple rotations.
In actual operation, place valve ball 3 in first runner earlier, and earlier with the lower extreme fixed connection of valve rod 3 on valve ball 3, bracing piece 4 through rotating the spiro union in the pipe thread, with the position of adjustment valve ball 3, thereby realize installing in first runner that valve ball 3 can be better, even after rotating valve ball 3 many times, make the skew take place for the position of valve ball 3, also can adjust through rotation bracing piece 4, and fix a position through locating pin 7 after the adjustment, prevent that bracing piece 4 from taking place the position change, therefore, the problem of installing in first runner that valve ball 3 can be better has been solved.
