Eccentric semi ball valve ANSI/API/DIN

1. Eccentric Semi Ball Valve consists of the main components such as valve body, eccentric axis, valve cover, ball crown, shaft cover, valve seat and other components. The valve is opened and closed by 90 ° by eccentric axis, which plays a role of cutting off the medium.
2. Eccentric Semi Ball Valvee ensures that during the opening or closing process of the valve, the valve seat and the ball crown do not rub each other. The eccentric hemisphere valve uses an eccentric crankshaft, so that the center line of the ball crown and the center line of the valve running away from a bias distance. When the valve is turned on, the crankshaft turns a small angle, and the ball crown will leave the valve seat, the ball crown and the valve seat will no longer be exposed; otherwise, during the closing process, the ball crown and the valve seat are only when the valve is closed. touch.
3.Eccentric Semi Ball Valve adopts the upper -mounted structure. During the maintenance process, there is no need to remove it from the pipeline. Just remove the bolt on the valve cover and remove the valve cover to remove the eccentric axis. This ensures that the valve can be online online. repair.
4. Eccentric Semi Ball Valve should ensure that the flow channel is completely unblocked when it is turned on, and the water head loss is small during runtime. The sphere adopts a semicircular channel, which has good circulation performance and linear regulatory performance, and impurities will not deposit in the cavity of the valve body.
5. Eccentric Semi Ball Valve should have sufficient strength. The eccentric crankshaft adopts a fixed ball structure. There is no vibration at a high current speed. The shell test is performed according to the national standard GB13927-1992.
6. Eccentric Semi Ball Valve is not allowed to have external leaks. At the upper and lower axis end, at least 2 O -shaped sealing is seal.
7. Eccentric Semi Ball Valve has the cutting function. When it is closed, the debris (branches, textile bags, etc.) in the medium can be cut off to ensure that the valve is open and closed normally.
