套筒调节阀有什么优点？

What are the advantages of sleeve regulating valves?

　　兼有单、双座阀的优点。主要有：

It has the advantages of both single and double seat valves. Mainly including:

　　1)稳定性好。因用阀塞节流代替阀芯阀座节流，而阀塞设有平衡孔可减少介质作用在阀塞上的不平衡力。同时套筒与阀塞间导向面大，加之不平衡力变化小，因此不易引起阀芯振动。

1) Good stability. Because valve plug throttling is used instead of valve core and valve seat throttling, and the valve plug is equipped with a balance hole to reduce the unbalanced force of the medium acting on the valve plug. At the same time, the guiding surface between the sleeve and the valve plug is large, and the change in unbalanced force is small, so it is not easy to cause valve core vibration.

　　2)互换性和通用性强。只要更换套筒就可得到不同的流量系数和不同的流量特性。

2) Strong interchangeability and versatility. By replacing the sleeve, different flow coefficients and flow characteristics can be obtained.

　　3)允许压差大，热膨胀影响小。带平衡孔的套筒阀的平衡原理和双座阀一样，因此许用压差大。又由于套筒、阀塞采用同一种材料制成，温度变化引起的膨胀基本一致。

3) Allow for a large pressure difference and minimal impact of thermal expansion. The balance principle of sleeve valves with balance holes is the same as that of double seat valves, so the allowable pressure difference is large. Due to the fact that the sleeve and valve plug are made of the same material, the expansion caused by temperature changes is basically the same.

　　4)套筒提供的节流窗口有开大口和打小孔(喷射型)两种。后者有降噪、减振作用，进一步改进即成专门的低噪音阀。

4) The sleeve provides two types of throttling windows: large opening and small hole punching (spray type). The latter has noise reduction and vibration reduction effects, and further improvements can be made to form specialized low-noise valves.

　　适用于阀前后压差大，噪音要求低的场合。

Suitable for situations with large pressure difference before and after the valve and low noise requirements.
