Design Characteristics Of Wear-Resistant Valves
1. Material selection:
Wear resistant valves typically use high hardness materials such as hard alloys, ceramics, silicon carbide, etc. These materials have excellent wear resistance and can effectively resist the erosion and wear of particulate matter in fluids.
The key components of valves, such as valve seats, valve cores, etc., are often made of wear-resistant alloys or composite materials to improve their service life.
2. Structural design:
The design of wear-resistant valves usually focuses on reducing fluid erosion and wear on the valve. For example, by optimizing the flow channel design of the valve, the fluid flows more smoothly inside the valve, reducing eddies and turbulence, thereby reducing wear.
The sealing surface of valves is usually made of wear-resistant materials and precision machined to ensure good sealing performance and wear resistance.
3. Maintenance convenience:
The design of wear-resistant valves usually takes into account the convenience of maintenance. For example, adopting a detachable structural design facilitates valve maintenance and replacement of worn parts.
Some wear-resistant valves are also equipped with online maintenance functions, which can be maintained without interrupting the process flow.
Design Features Of High Temperature Resistant Valves
1. Material high temperature resistance:
The main materials for high-temperature resistant valves are usually high-temperature alloy steel, stainless steel, titanium alloy, nickel based alloy, etc. These materials can maintain stable mechanical properties and corrosion resistance in high-temperature environments.
The key components of valves, such as valve discs and seats, are often made of high-temperature resistant hard alloys or ceramic materials to improve their high-temperature resistance and wear resistance.
2. Sealing structure:
The sealing structure of high-temperature resistant valves usually adopts metal hard seal or soft seal structure. The metal hard sealing structure has high temperature resistance and wear resistance, and is suitable for high temperature and high pressure environments.
The soft sealing structure uses high-temperature resistant elastic materials such as graphite, polytetrafluoroethylene, etc. to ensure good sealing performance of the valve in high-temperature environments.
3. Thermal expansion compensation:
The design of high-temperature resistant valves needs to consider the thermal expansion of materials at high temperatures. Usually, thermal expansion compensation devices such as expansion plugs and corrugated pipes are used to reduce the risk of valve deformation and leakage at high temperatures.
4. Cooling and protection:
In order to prevent valves from overheating at high temperatures, some high-temperature resistant valves are also equipped with cooling devices, such as cooling water jackets, air cooling devices, etc., to reduce the temperature of the valve.
In addition, key components of valves are often equipped with insulation protection measures to reduce damage to internal parts of the valve caused by high temperatures.
