What is the purpose of a gate valve?
The main purpose of the gate valve is used to cut off and connect the pipeline medium, its main functions and features include:
Opening and closing function: gate valve is mainly used to completely open or completely close, can not be used to regulate the flow or throttling control.
Sealing performance: gate valve through the valve seat and gate plate between the close contact to achieve good sealing performance, usually the sealing surface will be surfacing metal materials such as 1Cr13, STL6, stainless steel, etc., to increase wear resistance.
Flow resistance: gate valve fluid resistance is small, the internal medium channel of the valve body is straight through, making the medium into a straight line flow, which is conducive to the efficient transmission of fluids.
Applicable pressure and temperature: gate valve is suitable for a variety of pressure and temperature conditions, due to its structural characteristics, it can work stably in high temperature and high pressure environment.
Maintenance and repair: Although the structure and principle of the gate valve is relatively simple, but the maintenance and repair is relatively difficult, especially in the more serious occasions of corrosion.
Overall, gate valves play a vital role in pipeline engineering, especially in the need for frequent switching or high fluid control requirements.
