Further, described location sealing device comprises the first seal ring and the second seal ring that are located at valve inner, and the first described seal ring is provided with the first cambered surface with ball surface adaptation, and the second described seal ring is provided with the second cambered surface with ball surface adaptation.
Further, described valve body is provided with the positioning ring groove limiting stem position, and valve rod is provided with the locating bump with positioning ring groove adaptation.
Further, described valve body comprises mounting end and outlet end, and described valve body is provided with installation cavity, and the center line of installation cavity and the distance of mounting end are 13cm-15cm, and the extreme length of valve rod is 27cm-29cm, and the minimum diameter of valve body inner flow passage is 23cm-24cm.
Further, described valve rod is connected with handle, and is fixed by nut.
Contrast the deficiencies in the prior art, the beneficial effect that the technological scheme that the utility model provides is brought: 1. bonnet of the present utility model is for compressing the first seal ring, valve ball and the second seal ring, and the second cambered surface of the first seal ring first cambered surface and the second seal ring is fitted with the surface of valve ball respectively, play the effect of perfect sealing, the phenomenon that effective anti-fluid enters valve rod from the gap between valve body and valve ball occurs, and then the phenomenon preventing from getting rusty between valve rod and valve body and make ball valve damage occurs, and extends the working life of ball valve.2. the utility model is provided with positioning ring groove by valve body, and valve rod is provided with locating bump, locating bump is made to be stuck on positioning ring groove, and then valve rod is positioned in installation cavity, and in installation process, what valve rod need tilt enters mounting end and stretch in installation cavity, if the extreme length of valve rod is long relative to the minimum diameter of runner, so the angle of valve rod inclination is larger, and valve rod is not easy to put into installation cavity; If the extreme length of valve rod is just suitable for relative to the minimum diameter of runner, but, the center line of installation cavity and the distance of mounting end excessive, valve rod is also not easy to put into installation cavity, therefore, the center line of installation cavity and the distance of mounting end are set to 13cm-15cm, the extreme length of valve rod is set to 27cm-29cm, and the minimum diameter of valve body inner flow passage is set to 23cm-24cm, and valve rod can facilitate, be arranged in installation cavity easily, reduce work difficulty, improve working efficiency.
