The axis of the cooperation transmission of the sphere of valve rod and the first body cavity, valve rod passes through ball centre, the pipeline of first valve body to connect
Interface is communicated with the pipeline connection port of the second valve body, and the axis of pipeline connection port passes through ball centre, the sphere left end to pass through
First valve seat and the first valve body contact, the sphere right end are closed by the second valve seat and the second valve body contact, the valve seat of left and right two
Symmetrical in ball centre, first, second valve seat body is nested in by ring set third sealing ring in valve body recess, and described
One, the side of the second valve seat towards sphere is circumferentially provided with the first sealing ring, and first sealing ring and sphere sphere-contact are close
Envelope, the side of the first, second valve seat towards the valve body is circumferentially provided with the second sealing ring sealed with valve body contact.
Further, second valve body is fixedly connected on by installation bolt on the left of the first valve body, the installation of the first valve body
Face is equipped with the first limited post, and first limited post is matched with the seal groove of the second valve body mounting surface；Second valve body mounting surface
It is equipped with the second limited post, second limited post is matched with the seal groove of the first valve body mounting surface, first limited post
One group of sealing surface structure of composition adjacent with the second limited post.
Further, first sealing ring, the second sealing ring and third sealing ring are disposed as O-ring seal.
Further, the valve rod is equipped with circumferential recess in valve body within the sphere stage, nested on the groove
There is sealing ring.
The beneficial effects of the utility model are：The utility model has simple in structure, the good feature of elastic packing,
The first, second, third sealing ring of unique design generates elastic packing effect on first valve seat and the second valve seat so that this practicality
Novel to have good sealing performance, the setting of the second valve body has preload effect, when the valve seat insert bullet in the first valve body
Property reduced performance when, can screwing by the second valve body installation bolt, to inwardly squeeze the second sealing ring of the second valve seat, from
And so that sphere is compressed between the first valve seat and the second valve seat, and to make valve base seal property be restored, valve rod in addition
Equipped with circumferential recess, sealing ring is nested in circumferential recess can further reinforce valve inner and external barrier, reach
To sealed valve body effect.
