Product Introduction
The gate valve is a gate plate with opening and closing parts, the direction of movement of the gate plate is perpendicular to the direction of the fluid, and the gate valve can only be fully opened and closed, and cannot be adjusted and throttled.
How a gate valve works
The working principle of the gate valve is to control the on-off of the fluid through the lifting and lowering of the ram. When the ram rises, the fluid is allowed to pass through; When the ram is lowered, the fluid is blocked. The opening and closing parts of the gate valve are rams, and the direction of movement is perpendicular to the direction of the fluid.
Gate valve features
1. Good switching performance: The structure of the gate valve is simple, and the opening and closing are fast and reliable. The flow of the medium is controlled by moving the valve plate (ram) up and down. The ram provides a fully open or fully closed passage, resulting in less flow resistance during the opening and closing of the gate valve and less pressure loss of the fluid.
2. Good sealing performance: The gate valve adopts a parallel double gate structure, and the opening and closing operation is realized by moving the gate up and down. In the closed state, a completely sealed passage is formed between the two rams and the valve seat, which can effectively prevent the leakage of the medium.
3. Wide range of flow regulation: There is a straight channel between the flow channel and the gate plate of the gate valve, so it has a large flow area and a wide range of flow regulation of the fluid. It is suitable for some working conditions that require flow regulation.
