Stop and check the pneumatic butterfly valve in case of abnormal chatter during driving
With the development of science and technology, pneumatic butterfly valves are widely used in many industries. Today, I will introduce the role of pneumatic butterfly valves in the automotive industry and several common classifications. In order to improve the warmth of the driving process, most automobile suspension systems will be equipped with pneumatic butterfly valves. Pneumatic butterfly valves are mainly divided into hydraulic and pneumatic ones from the perspective of damping data, and there is also a pneumatic butterfly valve with variable damping.
Hydraulic pneumatic butterfly valve. Hydropneumatic butterfly valves are widely used in automobile suspension systems. The principle is that when the frame and axle reciprocate relative motion, the piston moves back and forth in the cylinder barrel of the pneumatic butterfly valve, the oil in the pneumatic butterfly valve housing flows from the inner cavity through some narrow pores into another cavity repeatedly. At this time, the friction between the liquid and the inner wall and the internal friction of the liquid molecules constitute the damping force for vibration.

The function of electromagnetic flowmeter in the market is also very different. The simple thing is to measure one-way flow, and only output analog signals to drive the rear instrument; Multifunctional instruments include two-way flow measurement, range switching, upper and lower limit flow alarm, air pipe and power cut alarm, small signal removal, flow display and total amount calculation, automatic verification and fault self diagnosis, communication with upper computer and motion configuration. The serial digital communication function of some models of instruments can select multiple communication interfaces and special chips (ASIC) to connect HART protocol system, PROFTBUS, Modbus, FF field bus, etc.
