First lug, the second lug, described valve seat is provided with the first locating slot embedded for the first lug and supplies the second lug embedding
The second locating slot entered.
Using technique scheme, owing to the first lug embeds in the first locating slot, the second lug embeds the second locating slot
In, so when valve rod drives core to rotate control valve opening and closing, sealing ring will not be extruded, it is thus possible to ensure the sealing of valve
Property stable.
Further setting of the present utility model: described valve seat include split arrange pedestal, gland, pedestal relative to
Gland is located off core side, and described pedestal is fixing with gland to be connected, described sealing ring between pedestal and gland,
On pedestal, gland, correspondence position is respectively equipped with first annular recess, the second annular notch, and first annular recess, the second annular are recessed
Interruption-forming annular groove, the first locating slot, the second locating slot are separately positioned on pedestal, gland.
Using above-mentioned further setting, this valve seat set-up mode, so that sealing ring is easier for installation；And
And, for the first locating slot, the second locating slot, annular groove processing the most convenient.
Further setting of the present utility model: be additionally provided with resin seal between described pedestal and core, pedestal sets
Resin filled channels, valve body is had to be provided with and the filling hole of resin filled channels conducting.
Use and above-mentioned further arrange, by resin seal, the sealing of valve can be improved further；The tree arranged
Fat filling channel, filling hole, can facilitate and resin is filled with operation, it is ensured that the sealing of valve is stable.
The most further setting of the present utility model: described pedestal is located off between end face and the valve body of core one end
It is provided with compression spring.
Using and above-mentioned the most further arrange, spring can provide certain thrust so that close between valve seat and core
Envelope property is more preferable.
The most further setting of the present utility model: be provided with sealing member between lateral wall and the valve body of described pedestal.
Use and above-mentioned the most further arrange, be possible to prevent medium to reveal from producing between valve body and valve seat.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model specific embodiment；
Fig. 2 is I part partial enlarged drawing in Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2, a kind of ball valve, include valve body 1, valve rod 2, in valve body 1, be provided with medium runner 3, medium runner 3
Inside being provided with core 4, valve rod 2 one end is linked with core 4 in extending to valve body 1, and the other end extends to outside valve body 1, medium stream
Being positioned at core 4 both sides in road 3 and be provided with valve seat 5, be provided with sealing ring 6 between valve seat 5 and core 4, valve seat 5 is provided with for sealing ring 6
The annular groove 51 snapped in, the face, outer ring of sealing ring 6 is outward extended with supporting part 61, and described supporting part 61 is to both sides respectively
Be extended with first lug the 62, second lug 63, described valve seat 5 be provided with for first lug 62 embed the first locating slot 52 with
And the second locating slot 53 for the second lug 63 embedding.Owing to the first lug 62 embeds in the first locating slot 52, the second lug 63
Embedding in the second locating slot 53, so when valve rod 2 drives core 4 to rotate control valve opening and closing, sealing ring 6 will not be extruded,
It is thus possible to ensure that the sealing of valve is stable.
