产品外形及结构尺寸示意图
 |
Globe valve, also called globe door, is the most widely used as a valve, the reason why it is popular is that the process of opening and closing the friction between the sealing surface is small, more durable, opening height is not easy to manufacture, easy maintenance, not only for low-voltage, and for high pressure.
Valve closure principle is to rely on bar valve pressure, the valve sealing surface and the valve seat sealing surface tightly, to prevent media circulation.
One-way valve can only medium flow direction when installing. Valve is greater than the gate length of the structure, and fluid resistance, long-term operation, sealing reliability is not strong.
