Stainless steel globe valve performance and principle

Stainless steel globe valve is a kind of valve which is widely used. The reason why the globe valve is popular is because the friction between the sealing surfaces is small during the opening and closing process, it is more durable, the opening height is not big, the manufacturing is easy, and the maintenance is convenient. Suitable for medium and low pressure, but also resistant to high pressure.

The closing principle of the shut-off valve is that, relying on the pressure of the valve bar, the sealing surface of the valve disc and the sealing surface of the valve seat are closely fitted to prevent the medium from flowing. The stainless steel globe valve allows only one-way flow of the medium and is directional when installed. The structural length of the shut-off valve is larger than that of the gate valve, and the fluid resistance is large. When the machine is operated for a long time, the sealing reliability is not strong.

Structure of the stop valve

The valve body structure of the stainless steel globe valve is of straight-through type, direct current type and right angle type. Straight-through is the most common structure, but its fluid resistance is greatest. DC fluid resistance is small, and it is mostly used for fluids containing solid particles or high viscosity. The right angle valve body is mostly forged, suitable for small through, high pressure shut-off valves.

The advantages of stainless steel globe valves:

1. Simple structure, convenient manufacturing and maintenance.

2. The working stroke is small and the opening and closing time is short.

3, good sealing, small friction between sealing surfaces, long life.
