The spring type safety valve refers to the lock -up of the valves valve or plunger and other seals such as the elastic pressure of the spring. Once the pressure of the pressure container is abnormal when the pressure container is abnormalA leakage channel was leaked off.
Spring type safety valve price
The market price of spring type safety valve is about 30-120 yuan.
Spring type safety valve structure
Spring -type safety valve structure Introduction Spring -type safety valve is generally composed of 10 parts, which are adjusted to adjust the screw, valve stem, spring, valve cover, guidance cover, anti -flushing plate, regulating ring, valve body, valve flap, and valve seat.The safety valve is classified according to the different structures. It can be divided into four types: lever, spring type, vertical hammer, and pulse type. The structure of each type is similar.In terms of safety valve, within the scope of the nominal pressure, the spring can be divided into several different types according to the working pressure level. The force and application range of each type are different.At this time, we must clarify the stress level you want, and then consider the medium, temperature, model and other aspects of the safety valve.
Spring type safety valve working principle
According to the analysis of the features of the spring -type safety valve, it can be concluded that under the influence of FW, a security valve from closed to opening, and then from opening to closingWhen the additional force increases gradually from zero, and the sum of the internal pressure PL × S is exactly the premature force of the spring, the valve is slightly enabled, which increases the medium effect area S, so that the internal pressure of the spring pre -tightening force is sharp.Increasing, the result reduced the additional force in an instant.As a result, the first feature peak A.When the additional force gradually decreases to the closing point, due to the sudden decrease in the area of ??the medium, in order to maintain the balanced relationship, at this time, the outer additional force will occur instantly, that is, the second feature peak point B.The above two characteristic peak points A and B are the technical basis for detecting the security valve to open the pressure and return pressure under the online conditions.
