The water inlet of valve body and the junction of water outlet, the sealing ring are fixed at the junction of the sphere Yu the valve body,
The both ends of first compressed spring are fixedly connected with the valve body and the sealing ring respectively, and the valve rod is fixed at
The top of the sphere, the valve rod and the valve body assembly connection, the filler combination are fixed at the valve body and institute
The junction of valve rod is stated, the both ends of second compressed spring are fixedly connected with the filler combination and the valve deck respectively,
The valve deck is fixedly connected with the valve body.
Further, the filler combination uses rubber material.
It further, further include floating bushing, the floating bushing is fixed between the sphere and first compressed spring.
It further, further include packing press ring, the packing press ring is fixed on the filler combination and the second compression bullet
Between spring.
Further, the corner of the valve body is designed using rounded corner.
Further, the water inlet of the valve body and water outlet are fixed with flange.
The utility model compared with prior art, the beneficial effect is that:
It is fixedly connected between valve deck and valve body, and then certain compressing force is provided for the second compressed spring, the second compression bullet
Spring is uniformly transmitted to pressure in filler combination by packing press ring, and filler combination uses rubber material, thus will appear shape
Become, and then the gap between valve rod and valve body can be filled up automatically and complete sealing, setting floating bushing plays reduction fluid scouring, protects
The interface of valve body and sphere is protected, the preload pressure of the first compressed spring can be compensated automatically between the friction between valve body and sphere
Gap.
