Types And Characteristics Of Forged Steel Gate Valves

A forged steel gate valve is a kind of gate valve widely used in pipelines, which mainly plays the role of connecting and disconnecting medium. It is not suitable to adjust the total flow of the medium, but the total flow can be judged according to the design elevation of the forged steel gate valve (for example, the elastic seat gate valve for fire protection is equipped with an opening and closing scale). Compared with other gate valves, forged steel gate valves have a wide range of applications for factors such as working pressure, ambient temperature, and specifications. According to the difference of internal structure, forged steel gate valve can be divided into wedge-shaped single gate valve, elastic gate valve, double gate valve and parallel gate valve. According to the difference of forged steel gate valve high pressure gate valve support, it is divided into: rising stem forged steel gate valve and rising stem forged steel gate valve.

gate
1. The flow resistance of the forged steel gate valve is relatively small. Since the oil circuit boards of the forged steel gate valve are connected to each other, the pressure loss of other valves is relatively small.
2. The sealing performance of the forged steel gate valve is better than that of the emergency shut-off valve, which saves effort in opening and closing.
3. Forged steel gate valve has a wide range of applications. In addition to being used for steam, oil and other media, it is also suitable for media with solid particles and low viscosity, and also suitable for automatic exhaust valves and gate valves in low vacuum systems.
4. The forged steel gate valve is a double flow valve, which will not be restricted by the inflow of the medium, so it is suitable for the medium to change the inflow pipeline, and it is also convenient for assembly. The structural properties of forged steel gate valves are comparative;

gate
(1) Wedge-shaped single-gate forged steel gate valve
a. The structure of forged steel gate valve is simpler than that of elastic gate valve.
b. The sealing performance of forged steel gate valves is not as good as that of elastic gate valve or double gate valve at continuous high temperature.
C. Forged steel gate valves are suitable for continuous high temperature media that are prone to slagging.

(2) Elastic water conservancy gate forged steel gate valve
a. Forged steel gate valve is a unique wedge-shaped single gate valve. Compared with the wedge gate valve, the sealing performance is good at high temperature, and the gate valve is not easy to be stuck after being heated;
b. Forged steel gate valves are suitable for steam, continuous high-temperature refined oil and gas media, and for components that are frequently changed.
c. Forged steel gate valves are not suitable for slagging media.
