Globe Valve working principal:
globe valve, also called globe door, is the most widely used as a valve, the reason why it is popular is because 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. Valve has the following advantages:
1, simple structure, manufacturing and maintenance more convenient.
2, the working stroke is small, open and close a short time.
3, sealing, and sealing surface between the friction force is small, longer life expectancy. Valve has the following advantages:
