Resilient seat gate value
The resilient seat gate value can be divided into two types according to the thread position on the valve stem. From the structural characteristics of the gate, it can be divided into wedge type and parallel type.
The sealing surface of the resilient wedge gate value is at an angle to the vertical center, and is mostly made of a single gate. The sealing surface of resilient wedge gate values is parallel to the vertical center, and most of them are made of double gates.
The sealing performance of the resilient seat gate value is better than that of the stop valve, the fluid resistance is small, and it has a certain adjustment performance. The exposed rod type can still adjust the opening and closing degree according to the height of the valve stem. The disadvantage is that the structure is more complicated than the stop valve, the sealing surface is easy to wear, and it is not easy to repair. In addition to suitable for steam, oil and other media, gate valves are also suitable for media containing granular solids and high viscosity, and are suitable for venting valves and valves for low vacuum systems.
The elastic resilient seat gate value is not easy to be stuck after being heated. It is suitable for steam, high-temperature oil, oil and gas and other media, and parts with frequent opening and closing. It is not suitable for media that is easy to coke.
The resilient wedge gate value has a simpler structure than the elastic gate valve, and its sealing performance is not as good as the elastic or double gate valve at higher temperatures. It is suitable for high temperature media that is easy to coke.
The double resilient wedge gate value has good sealing performance, and it is easy to repair after the sealing surface is worn out, and its parts are more than other types. It is suitable for steam, oil, and medium that has a lot of wear on the sealing surface, or for frequent switching positions, and not suitable for medium that is easy to coke.
Compared with resilient seat gate values, it has good adjustment performance, poor sealing performance, simple structure, convenient manufacturing and maintenance, large fluid resistance, low price, suitable for steam and other media, not suitable for use and medium with high viscosity, containing particles, and easy to precipitate. For vent valve and low vacuum system valve.
The throttle valve is small in size, light in weight, and has better adjustment performance than globe valves and needle valves, but the adjustment accuracy is not high. Due to the high flow rate and easy erosion of the sealing surface, it is suitable for the medium with low temperature and high pressure, as well as the parts where the flow and pressure need to be adjusted. It is not suitable for the medium with high viscosity and containing solid particles, and it is not suitable for blocking valves.
