Design considerations
Material selection: Select the appropriate material according to the fluid properties (such as temperature, pressure, and corrosiveness).
Valve size: It needs to match the pipe size to ensure the rationality of flow and pressure drop.
Sealing performance: Select high-quality sealing materials to ensure that the valve does not leak water or air when closed.
Water treatment: used to adjust the water flow in cooling water and heating water systems.
Refrigeration system: Control refrigerant flow to achieve efficient refrigeration.
Steam system: used to precisely adjust the steam flow in steam heating and steam recovery systems.
Air Handling: Controls air flow in air handling units to achieve good indoor air quality.
FAQ
1.What are the considerations for the use of stop valves with other types of valves?
When selecting other valves, it is necessary to consider the fluid flow characteristics, pressure loss, control requirements, and compatibility of the overall system design.
2.How to determine whether the 3 4 inch globe valve needs to be replaced?
If the valve frequently leaks, cannot be opened or closed normally, or the sealing performance is significantly reduced, it is necessary to consider replacing it.
3.What is the flow characteristic curve of the stop valve?
The flow characteristics of the stop valve usually show a nonlinear relationship, and the relationship between the flow and the valve opening may be asymmetric.
4.What precautions should be taken when using the 3 4 inch globe valve at extreme temperatures?
High temperature environments may cause the valve material to deform, while low temperature environments may cause the material to become brittle, so it is necessary to select materials that are resistant to high and low temperatures.
5.Why is it sometimes necessary to install a filter in front of the stop valve?
The filter can prevent impurities in the fluid from entering the valve, thereby increasing the service life of the valve and the overall performance of the system.
