Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the utility model provides a kind of technical solution：The ball valve of the good seal performance, including valve body 1,
The valve body 1 is set for tube body, and the upper and lower ends of valve body 1 are respectively equipped with outlet 2 and import 3, the valve body 1 are internally provided with
Sphere 5, the corner of the sphere 5 are symmetrically equipped with four groups of valve seats 11, arc groove are equipped with the inside of the left wall of the valve body 1
10, the outer end of the valve seat 11 is fixed by the left end of the inside and sealing plate 4 of compression spring 12 and arc groove 10 respectively to be connected
Connect, the right end of the sphere 5 is fixedly connected by threaded rod 16 through the inside of sealing plate 4 with one end of handle 7, the spiral shell
Rasp bar 16 is from left to right equipped with spring energy-storage sealing ring 14 and water expandable waterstop 15 successively with 4 inside junction of sealing plate.
Specifically, the right end of the valve body 1 is integrally formed with annular connecting plate 8, the annular connecting plate 8 and sealing plate 4
It is fixedly connected by bolt 9, facilitates the installation of sealing plate 4.
