Valve closed, sealing surface can only rely on Rising Stem Resilient Seated Gate Valve media pressure to seal, in which the medium pressure to ram pressure to the other side of the sealing surface of the valve seat to ensure the sealing surface of the seal, which is a self-sealing.

闸阀关闭时，密封面可以只依靠介质压力来密封，即依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封，这就是自密封。

This paper consider centrifugal force and coriolis force for ideas of Planetary LabCD Valve Model and Single Point Fluid Separation Model, then the relation of critical rotation speed and planetary angle is linear which control parameter of critical rotation speeding in the Planetary LabCD Valve Model and compare with James Lee theory, and define γR in SPFS Valve Model to show the relation of the low rotation speed is linear and is fixed where the high rotation speed for utilizes any rotation speed.

本论文考虑离心力与科氏力之影响，且提出行星式碟片阀门模式与单点流体分离阀门模式两模式，其中行星式碟片阀门模式，其临界转速与行星角之大小近於线性变化，可当於控制阀门之临界转速之设计参数，且比较在阀门设计上考虑行星角来控制阀门临界转速与James Lee之阀门临界转速理论可以得知，从吾人所提出行星式碟片阀门模式可以得到与实验结果相同的趋势。

However, this butterfly valve in the course of the following questions remain: First, as a result of hard and soft multi-layer stacked ring fixed in the valve plate, when the valve plate when the media always state of the formation of its positive sealing surface erosion, sheet metal dissection of the soft-sealed after flushing with by a direct impact on seal performance.

但是，这种蝶阀在使用过程中仍然存在以下问题：一、由于多层软硬叠式密封圈固定在阀板上，当阀板常开状态时介质对其密封面形成正面冲刷，金属片夹层中的软密封带受冲刷后，直接影响密封性能。

Now, this is not the case, a single-seat valve, two-seat valve, valve sleeve has been the same use.

到如今，并非如此，单座阀、双座阀、套筒阀都得到同等的使用。

This structure effectively compensate for tolerance between the sleeve and the valve body and valve stem in the medium with the elastic deformation under pressure to solve the two-way valve in the transmission medium interchangeable sealing problems existing in the process.

这种结构有效地补偿了轴套与阀体之间的公差带及阀杆在介质压力下的弹性变形，解决了阀门在双向互换的介质输送过程中存在的密封问题。

First, choose the type of structure Double seal type valve (eg, valve seat, double sealed sleeve valve, etc.) is one of the major shortcomings of a large leak.

一、结构型式的选择双密封类调节阀（如双座阀、双密封套筒阀等）主要的缺点之一就是泄漏大。

This paper analyzes the steady-state characteristic of the two main components of the water hydraulic proportional throttle valve including slide valve and proportional solenoid, and analyzes the whole valve's steady-state characteristic also.

论文分析了水压比例节流阀的两个主要组成部分––––节流滑阀和比例电磁铁的稳态特性，并对水压比例节流阀整体的稳态特性进行了分析。

The place with 5 valve most clove of Beijing is sweet hill , the lilac breed near coloured glaze tower and clear temple is distinctive , the slue of 5 valve , have 6 segment or section even of 7 valve .

北京五瓣丁香最多的地方是香山，琉璃塔和昭庙附近的丁香花品种特异，5瓣的极多，甚至有6瓣7瓣的。
