The gate valve (gate valve) is a gate of the opening and closing part. The direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact between the valve seat and the gate plate. Usually, the sealing surface will be surfacing with metal materials to increase wear resistance, such as surfacing welding 1Cr13, STL6, stainless steel, etc. There are rigid gate valves and elastic gate valves. According to the different gate valves, gate valves are divided into rigid gate valves and elastic gate valves. So how do we choose the gate valve?
1. Understand the types of gate valves
There are many different types of gate valves such as parallel gate valves, wedge gate valves, two-way gate valves, etc. When selecting a gate valve, it is necessary to determine the appropriate type according to the pipeline conditions and usage requirements.
2. Determine the specifications and dimensions of the gate valve
When selecting the specification and size of the gate valve, the flow requirements and pressure rating of the pipeline need to be considered. The specification and size of the gate valve should match the specification and size of the pipeline to ensure that the gate valve can effectively control the flow of fluid.
3. Consider the material of the gate valve
The material of the gate valve usually depends on the use environment and pipeline conditions. For example, in high temperature and high pressure environments, it is usually necessary to use superalloys or materials with better corrosion resistance.
4. Understand the performance of gate valves
When selecting a gate valve, it is also necessary to understand the performance of the gate valve, such as opening and closing force, sealing performance, wear resistance, etc. These properties will directly affect the efficiency and reliability of the gate valve.
In short, when selecting a gate valve, it is necessary to consider comprehensively based on factors such as the use environment, pipeline conditions, flow requirements, and valve performance, so as to ensure that the gate valve can effectively control the flow of fluid and improve the working efficiency of the pipeline system.
