By adopting the above further arrangement, the hollow pressing sleeve fixes the viewing window on the premise of not obstructing the viewing effect of the viewing window.

The utility model discloses a still further set up: a channel is arranged in the ball body, and the channel is T-shaped or L-shaped.

By adopting the further arrangement, the ball valve can be used for a common three-way ball valve in the market, and has wide application range.

The utility model discloses a still further set up: the pressure cover is installed at the rear of the valve seat, trapezoidal graphite is installed among one end face of the pressure cover, the inner walls of the valve seat and the valve body in a sealing mode, and a spring is installed between the other end face of the pressure cover and the valve body.

By adopting the above further arrangement, the trapezoidal graphite increases the temperature application range of the valve, and the spring forms elastic sealing force on the valve seat, so that the sealing performance of the valve seat and the ball body is improved, and leakage is prevented.
