安全阀可以分为介质作用于滑阀下面的阀和介质作用于滑阀上面和完成开启动作的某个灵敏元件上的阀。 第一种型式的安全阀,其密封件的密封是特别困难的。压力作用于滑阀下面的阀的密封处密封比压的最大值按照文献[1]的公式计算,在大多数情况下小于保证密封所必需的值。 密封处密封比压值之所以小,是因为对于所探讨结构的阀,介质压力所作用的灵敏元件的面积不大。介质作用于滑阀上面的安全阀没
The safety valve can be divided into a medium acting on the valve under the valve and a valve acting on one of the sensitive elements acting on the valve and completing the opening action. The first type of safety valve, the seal of the seal is particularly difficult. The pressure applied to the seal at the valve below the slide valve The maximum value of the seal specific pressure is calculated according to the formula in [1] and in most cases less than the value necessary to ensure the seal. The reason why the seal is smaller than the pressure value is because the area of the sensitive element that the medium pressure acts on is small for the valve in question. Medium acting on the valve above the safety valve did not
