Spring safety valve and Failure Analysis

The spring safety valve is set up for the exhaust pipe is blocked due to misuse or cleaning device. The spring safety valve is a the limited pressure cooker safety pressure within the exhaust to ensure the safe use of the device. The spring structure, performance of the valve is critical.
In accordance with the maximum height of the valve to open the safety valve flow channel diameter ratio divided, spring safety valve can be divided into spring Weiqi closed two kinds of safety valve for high pressure safety valve and spring.
The spring Enlight closed pressure safety valve angle seat valve

Weiqi safety valve opening height is less than 1/4 of the diameter of the flow channel, usually as a runner diameter of 1/40 1/20. Weiqi safety valve action is proportional to the acting, is mainly used for the liquid occasions, also sometimes used for small gas emissions occasions.
Spring safety valve
The safety valve opening height is greater than or equal to 1/4 of the diameter of the flow channel. A safety valve discharge area of ​​the minimum cross-sectional area of ​​the valve seat throat. The course of action is to belong to the two-stage acting, must be by means of a lift mechanism in order to achieve the full open safety valve for gas medium occasions.
In safety valve
The height of the opening between between Weiqi the entire Kai. That can be made into a two-stage role can also be made proportional acting.
