Points for attention
The difference between electric proportional valve and solenoid valve
Valve control of flow can be divided into two types:
One is switch control: either fully open or fully closed, the flow rate is either maximum or minimum, there is no intermediate state, such as ordinary electromagnetic through valve, electromagnetic reversing valve, electro-hydraulic reversing valve. The other is continuous control: the valve port can be opened according to the need of any degree of opening, thereby controlling the size of the flow through, such valves have manual control, such as throttle valves, but also electronically controlled, such as proportional valves, servo valves. So the purpose of using proportional valve or servo valve is: to achieve the flow control by electronic control (of course, after structural changes can also achieve pressure control, etc.), since it is throttling control, there must be energy loss, servo valve and other valves are different, its energy loss is greater, because it needs a certain flow to maintain the work of the pre-stage control oil circuit.
Electromagnetic valve (Electromagnetic valve) is the use of electromagnetic
Working principle of proportional solenoid valve
Electro-hydraulic proportional valve is the proportional electromagnet input voltage signal in the valve to produce corresponding action, so that the working valve spool displacement, valve mouth ruler
Inch changes and thus completes the pressure, flow output element proportional to the input voltage. Spool displacement can also be mechanical, hydraulic or
Electrical form for feedback. Electro-hydraulic proportional valve has a variety of forms, easy to form the use of electrical and computer control of various electro-hydraulic system System, high control accuracy, flexible installation and use, strong anti-pollution ability and other advantages, the application field is expanding day by day. Recent research and development The production of plug-in proportional valves and proportional multi way valves fully consider the characteristics of the use of construction machinery, with pilot control, load sensing and pressure Compensation and other functions. It is of great significance to improve the overall technical level of mobile hydraulic machinery. Especially electronically controlled pilot operation,Wireless remote control and wired remote control operation have shown a good application prospect.
