Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model 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 embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.

As shown in Figure 1, the ball valve include shell 10, set on 10 one end of shell end cap 20, be contained in the shell 10 Valve base sealing 30, the ball valve body 50 that is movably arranged in valve base sealing 30 and be connected on ball valve body 50 and ball valve can be driven The handle 60 that body 50 rotates.

The shell 10 includes a columnar ontology 11 and the connecting tube 12 extended outward by one end of ontology 11.It should The one end open opposite with interconnecting piece 12 of ontology 11, being screwed together has a junction block 13.The connecting tube 12 and junction block 13 Periphery is respectively equipped with screw thread.The connecting tube 12 is respectively used to connect with a fluid ingress pipe and a fluid outlet conduit with junction block 13 It connects.The bottom end of the shell 10 is equipped with a tap 16 communicated with the external world.

The valve base sealing 30 can be made of the good plastics of wearability, self-lubricity, and concretely polyfurolresin seals.It should The pore for the pore and junction block 13 that valve base sealing 30 is correspondingly connected with pipe 12 is equipped with opening 31.The ball valve body 50 can it is comfortable actively It is resisted against in valve base sealing 30.It is equipped in the ball valve body 50 across 50 both ends of ball valve body and corresponding with the opening of valve base sealing 30 31 The through-hole 51 of connection.Please refer to Fig. 2, in the present embodiment, the side of the ball valve body 50 is equipped with a notch 52, the notch 52 The part of the opening 31 of top and valve base sealing 30 is in the same plane.Please refer to Fig. 3, when it is implemented, the notch 52 It can be the connection ditch being inwardly recessed by the surface of ball valve body 50.The top of the ball valve body 50 is connected with a shaft 53.The shaft 53 top is connect with handle 60, and the handle 60 rotation drives shaft 53 to be connected to ball valve body 50 and rotates.

The periphery that the shell 10 corresponds to shaft 53 is outward extended with a sleeve 18 upwards, and the side of the sleeve 18 is extended with one Flange 17.A sliding slot 19 is equipped in the flange 17.The position bending that the handle 60 corresponds to sliding slot 19 is extended with a setting sliding slot 19 Interior positioning region 61.The handle 60, which drives positioning region 61 that can be slided along sliding slot 19, makes ball valve body 50 along a certain clockwise rotation 90 Make the notch 52 of ball valve body 50 opposite with 31 part of opening of valve base sealing 30 after degree, the setting of the sliding slot 19 limits positioning region 61 Sliding trace, prevent its sliding reversed or not in place.

In use, fluid is entered by connecting tube 12, by the opening 31 of valve base sealing 30, then the through-hole by ball valve body 50 It is discharged by junction block 13 after 51, after fluid passes through, by swing handle, makes the through-hole 51 and valve base sealing of ball valve body 50 30 opening 31 does not correspond to, and keeps the notch 52 of ball valve body 50 corresponding with the opening 31 of valve base sealing 30, residual in shell 10 to make Remaining fluid is discharged by the tap 16 of notch 52 and the lower section of shell 10, and then is prevented fluid residuals and influenced the use of ball valve Service life.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection domain within.
