Kf-L20e Pressure Gauge Valve Hydraulic Valve Switch Valve Hydraulic Instrument Kf Series Pressure Gauge Switch

The hydraulic pressure gauge switch is the key element used to control the on-off between the pressure gauge and the hydraulic oil circuit in the hydraulic system. The following is a detailed introduction:
 
-Product definition: the hydraulic pressure gauge switch is a small valve device. Its main function is to control the connection and disconnection between the pressure gauge and the hydraulic system, so as to realize the accurate measurement and monitoring of the pressure of the hydraulic system.
-Working principle: control the position of valve core by manual rotation or electromagnetic drive. When the valve core is open, the pressure oil of the hydraulic system can flow into the pressure gauge to make the pointer of the pressure gauge rotate and display the current system pressure; When the valve core is closed, the passage between the pressure oil and the pressure gauge is cut off, and the pressure gauge no longer displays the system pressure, which also protects the pressure gauge from the impact of system pressure fluctuation.
-Structure composition: mainly composed of valve body, valve core, regulating handle, seal and other components. The valve body provides space for installation and oil flow. The valve core is responsible for controlling the on-off of the oil circuit. The adjusting handle is convenient for the manual operation of the operator. The sealing element ensures the tightness of the connection to prevent oil leakage.
-Product features: it has the characteristics of small volume, compact structure, simple operation, stable performance, etc., and can work stably under high pressure, vibration and other adverse conditions. It can adapt to a variety of hydraulic oil media, and is convenient for maintenance.
-Application scenario: it is widely used in various hydraulic systems such as engineering machinery, metallurgical equipment, petrochemical industry, and injection molding machinery to provide key pressure data for the safe operation and maintenance of equipment.
KF hydraulic pressure gauge switch is a small stop valve or throttle valve. It is mainly used to cut off the connection between the pressure gauge and the oil circuit. It can also adjust the opening to play a damping role, reduce the sharp jump of the pressure gauge and prevent damage. It can also be used as a general small flow stop valve or throttle valve. The pressure oil interface has internal and external thread connection.

 

 

1. question: what is the main function of the hydraulic pressure gauge?
-Answer: it is used to measure and display the pressure in the hydraulic system to help the operator understand the pressure state of the system and ensure the normal operation of the system.
2. question: how to select the appropriate range of hydraulic pressure gauge?
-Answer: generally, the measuring range is 1.5-3 times of the maximum working pressure of the system, which can not only ensure the measurement accuracy, but also prevent the pressure gauge from being damaged by excessive pressure.
3. problem: what is the reason for the serious jitter of the pointer of the hydraulic pressure gauge?
-Answer: it may be that the system pressure fluctuates greatly, or the installation position of the pressure gauge vibrates greatly, or the damper fails.
4. problem: how to deal with the inaccurate reading of the hydraulic pressure gauge?
-Answer: first, check whether the pressure gauge is used beyond the range. Second, check whether the pressure gauge is damaged. If it is damaged, replace it; It is also necessary to check the connecting pipeline for leakage, and repair it in time if there is any leakage.
5. question: does the hydraulic pressure gauge need to be calibrated regularly?
-Answer: Yes, regular calibration can ensure the accuracy of pressure gauge measurement. Generally, the calibration cycle is determined according to the frequency of use and accuracy requirements, usually half a year to one year.
