Embodiment 1

[0022] Example 1: figure 1 Combine figure 2 The two ends of the middle valve body 1 are the water inlet 2 and the water outlet 3 respectively. The upper valve body 4 is arranged on the side of the valve body 1, and the shell of the upper valve body 4 is a cylindrical lock cap 5 whose bottom is connected with the water inlet 2 , The upper part of the lock cap 5 is provided with a rotating shaft 6, the upper end of the rotating shaft 6 extends out of the top of the lock cap 5, and is connected to a floating ball 8 through an adjusting arm 7. The part of the rotating shaft 6 located in the lock cap is provided with a positioning step 9. The upper part of the positioning step 9 is provided with a moving washer 10 tightly fitted with the rotating shaft 6, and the upper part of the moving washer 10 is provided with a static washer 11 and a static washer 11. A shaft sleeve 12 is provided on the upper end; the bottom end of the rotation shaft 6 in the lock cap 5 is fixedly connected to ...

Embodiment 2

[0025] Embodiment 2: The static valve through hole 17 and the moving valve notch 15 can adopt square holes, and the others are the same as in embodiment 1.

Embodiment 3

[0026] Embodiment 3: The above-mentioned locking position for restricting the radial movement of the static valve 15 is a locking rib, and a locking groove corresponding to the locking rib is provided on the circumference of the corresponding static valve 15, and the others are the same as in Embodiment 1.

Abstract

The invention discloses the ball float valve with the performances of good sealability, stable operation, high temperature resistance and long service life. The valve includes the valve body, the axis of rotation and the ball float, which through the joint sleeve connects to the upper end of the axis of rotation. The water inlet and outlet are positioned at the two ends of the valve respectively. The upper valve body with the columnar lock cap being as the outer covering is set up at the side face. The axis of rotation enters into the lock cap. There are the mobile spacer, static spacer, the shaft sleeve as well as the mobile valve and static valve. The mobile valve and static valve can be connected each other or closed. The through hole located at the place corresponding to the mobile valve is connected to the outlet of the valve.

Description

Technical field: [0001] The invention relates to a valve, particularly a floating ball valve. Background technique: [0002] The float valve currently used in water towers and other places is composed of floats, brackets, rotating shafts, rubber gaskets, etc. Because the opening surface relies on rubber seals, it has poor aging resistance, easy deformation and instability, and cannot work at high temperatures; along the axial direction There is no positioning in the radial direction, so that the closing end face is not vertical and the force is uneven, so the closing end face needs a greater force to close; due to the unreasonable structure, the sealing performance is poor, and it cannot withstand higher water pressure and is easy to leak. The service life is short. Summary of the invention: [0003] The invention solves the problems of poor sealing performance, unreasonable structure, unstable operation and short life of the existing float valve, and designs a float valve with ...
