Solenoid valve response time, solenoid valve response time test method

Solenoid valve response Time

Under the requirements of high standard working conditions, Solenoid valve Long or short response time is also a very important factor. The following solenoid valve technical manual is an example to introduce the response time of the solenoid valve.

The solenoid valve changes from fully closed to fully open (or On the contrary) the reaction time depends on the valve's nominal diameter, action mode, starting current and power, fluid medium type and viscosity, inlet pressure and working pressure difference, etc.

For diameter DN≤50, the fluid medium is Gas, when the pressure P≤1Mpa:

Generally straight The reaction time of the dynamic solenoid valve is 15-60ms, the reaction time of the pilot solenoid valve is 20-250ms, and the reaction time of the recoil type solenoid valve tends to be close to that of the direct-acting solenoid valve.

When the medium used is liquid, the response time of the solenoid valve An increase of approximately 50-100% compared to the values ​​listed above.

When using a DC solenoid valve, the response time is longer than the values ​​listed above increased by approximately 50%.

Due to the varying parameters of the test solenoid valve response time There are many, and generally the response time of each valve cannot be provided. It is provided according to the user's needs and specified test conditions.

Solenoid valve response time test method

The solenoid valve is receiving action There is a response time between the instruction and the completion of the action. In some applications that require high response from solenoid valves, accurate estimation is requiredThe response time of the solenoid valve provides correction parameters for the control of the solenoid valve .

No matter what the valve is, its response time test The principle is: give the subject an incentive and record the output curve of the subject. The abscissa is time. According to the definition of response time in "Automatic Control Principle", the time for 5%-95% amplitude output is the response time.
