In fig. 1: 1. a valve body; 2. a valve cavity; 3. a valve ball; 4. a valve stem; 5. a handle; 6. a water inlet; 7. a water outlet; 8. sleeving a ring hole; 9. a valve seat; 10. a compression spring; 11. a seal ring; 12. disassembling and assembling holes; 13. a bolt; 14. disassembling and assembling the seal cover; 15. a graphite sealing gasket; 16. graphite sealing filler; 17. connecting steps; 18. and (5) sealing rings.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.
The utility model provides a fixed ball valve.
In this embodiment, refer to fig. 1, this fixed ball valve, including valve body 1, set up valve ball 3 in valve pocket 2 of valve body 1, stretch into valve rod 4 that the valve pocket and valve ball linked firmly and the handle 5 of being connected with the valve rod, the both ends of valve pocket are equipped with water inlet 6 and delivery port 7, be equipped with suit annular ring 8 in the valve pocket, the disk seat 9 is equipped with to suit annular ring endotheca, the cover is equipped with compression spring 10 between disk seat and the suit annular ring diapire, the embedding hole on the sealed complex of disk seat and valve ball seals face has embedded sealing ring 11, the bottom of valve body is equipped with dismouting hole 12, the dismouting hole is fixed with dismouting closing cap 14 through bolt 13.
Among the above-mentioned technical scheme, through setting up disk seat and valve body separation to set up dismouting hole and dismouting closing cap in the below of valve body, after wearing and tearing appear in the sealing member, can directly pull down the dismouting closing cap and change the sealing member, help improving the life of ball valve, avoid unnecessary extravagant.
