The utility model discloses a realize through following technical scheme:
the utility model provides a ceramic ball valve, including right valve body and left valve body, the inside of right valve body and left valve body is equipped with the valve ball, the valve ball adopts ceramic material, be equipped with the disk seat between the upper end of right valve body and left valve body, be equipped with down the disk seat between the lower extreme of right valve body and left valve body, link together through last disk seat and lower disk seat between right valve body and the left valve body, the inside of right valve body and left valve body respectively is equipped with a bush, the bush adopts ceramic material, the medial surface of bush is laminated with the upper and lower terminal surface of valve ball, respectively be equipped with two elastic rings on two upper and lower internal ring surfaces that right valve body and left valve body formed, the upper end of valve ball is equipped with the valve rod, install the handle on the valve rod, the lower extreme of valve ball is equipped with lower valve rod, all overlap on upper valve rod and the lower valve rod and have the bearing, the outer lane of bearing pastes with the inner wall of upper valve.
The bearing is arranged between the valve rod and the valve seat, so that the abrasion is greatly reduced; the valve ball and the lining sleeve which are made of ceramic materials are tightly attached, when the valve ball is impacted, the impact force between the valve ball and the lining sleeve can be transferred to the elastic ring, the damage to the valve ball and the lining sleeve is greatly reduced, and the service life is prolonged.
Further preferably, the elastic ring is made of rubber.
Further preferably, flange connection discs are arranged at the outer side ends of the left valve body and the right valve body.
Compared with the prior art, the utility model discloses the beneficial effect who has is:
the bearing is arranged between the valve rod and the valve seat, so that the abrasion is greatly reduced; the valve ball and the lining sleeve which are made of ceramic materials are tightly attached, when the valve ball is impacted, the impact force between the valve ball and the lining sleeve can be transferred to the elastic ring, the damage to the valve ball and the lining sleeve is greatly reduced, and the service life is prolonged.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of a portion A of FIG. 1;
fig. 3 is a partially enlarged structural diagram of a portion B in fig. 1.
In the figure: 1. a right valve body; 2. an upper valve seat; 3. a valve ball; 4. a bushing; 5. an upper valve stem; 6. a handle; 7. a lower valve stem; 8. an elastic ring; 9. a bearing end cap; 10. a bearing; 11. a left valve body; 12. and a lower valve seat.
Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1 to 3, a ceramic ball valve comprises a right valve body 1 and a left valve body 11, flange connection discs are arranged at the outer ends of the right valve body 1 and the left valve body 11, a valve ball 3 is arranged inside the right valve body 1 and the left valve body 11, the valve ball 3 is made of ceramic materials, an upper valve seat 2 is arranged between the upper ends of the right valve body 1 and the left valve body 11, a lower valve seat 12 is arranged between the lower ends of the right valve body 1 and the left valve body 11, the right valve body 1 and the left valve body 11 are connected together through the upper valve seat 2 and the lower valve seat 12, a lining 4 is respectively arranged inside the right valve body 1 and the left valve body 11, the lining 4 is made of ceramic materials, the inner side surface of the lining 4 is attached to the upper and lower end surfaces of the valve ball 3, two elastic rings 8 are respectively arranged on the upper and lower inner ring surfaces formed by the right valve body 1 and the left valve body 11, the elastic rings 8, install handle 6 on the last valve rod 5, the lower extreme of valve ball 3 is equipped with lower valve rod 7, goes up and all overlaps on valve rod 5 and the lower valve rod 7 and have bearing 10, and the outer lane of bearing 10 pastes with the inner wall of last disk seat 2 and lower disk seat 12 mutually, and the outside of bearing 10 is equipped with bearing end cover 9, and bearing end cover 9 passes through the bolt and installs on the disk seat.
