Electromagnetic overflow pneumatic valve working principle and function

in hydraulic equipment, electromagnetic overflow can have constant pressure pneumatic valve for unloading overflow, system and safety protection and favored by many domestic outfit consumer. However it is not very understanding, a lot of users to it doesn't matter, below small make up for everybody introduced electromagnetic overflow pneumatic valve working principle and function. Electromagnetic overflow working principle of the pneumatic valve

electromagnetic overflow on the principle of pneumatic valve, generally is by the pilot operated relief pneumatic valve with a bit of an electromagnetic air valve. The solenoid pneumatic valve actually consists of two parts: one part of hydraulic pneumatic valve, plus an electromagnet. A vent valve is opened, or closed, pneumatic valve core movement is driven by electromagnet. Pneumatic valve electromagnet electricity when open, pneumatic valve electromagnet is cut open, and her eyes green vegetables personal love ( According to the system requirements.
that is to say, there is a pathway a pneumatic valve and pilot overflow to certain parts of the pneumatic valve is linked together, on the other side are connected to the fuel tank through the tubing. By manipulating the electromagnet can make pilot overflow to certain parts of the pneumatic valve or with the fuel tank, or not with the fuel tank.
the forerunner overflow on the Lord of the pneumatic valve pneumatic valve cavity pressure is controlled by the forerunner of pneumatic valve. If the forerunner pneumatic valve work normally, or main pneumatic valve cavity with the guide of pneumatic valve pressure, the overflow of pneumatic valve will be in the system pressure reaches the setting its main pneumatic valve to open the mouth opening, on the one hand, can the system redundant traffic flow back to the fuel tank, on the other hand also can maintain the system pressure as the forerunner of the pneumatic valve setting. Visible, the forerunner of pneumatic valve main pipe pressure, the main pneumatic valve to obey the forerunner the leadership of the pneumatic valve, pneumatic valve in the guide moves to the pneumatic valve is open to a suitable size, excess flow out go to, just do not affect the system pressure again.

electromagnetic overflow pneumatic valve action, constant pressure overflow effect: in quantitative pump throttle control system, the quantitative pump provides a constant flow rate. When the system pressure, can reduce traffic demand. At this point the overflow pneumatic valve open, excessive flow back to the fuel tank, ensure the overflow pneumatic valve inlet pressure, pump outlet pressure constant ( Pneumatic valve open mouth often fluctuates according to pressure.
and voltage stabilizing role: overflow series pneumatic valve on the back to the oil, the overflow back pressure pneumatic valve, the moving parts of increase.
unloading effect, the system: in the overflow of the pneumatic valve remote control mouth concatenated small flow pneumatic valve, electromagnetic spill when the electromagnet electricity, the overflow mouth of pneumatic valve remote control fuel tank, hydraulic pump unloading at this time. The overflow of pneumatic valve used as unloading pneumatic valve at this time.
, safety protection: system to work normally, the pneumatic valve is closed. Only load in excess of the prescribed limit, The system pressure exceeds setting pressure to open the overflow, overload protection, no longer increases the system pressure ( Usually make the overflow of the pneumatic valve setting pressure % ~ % higher than system maximum working pressure.
that is about the electromagnetic overflow pneumatic valve working principle and function of introduction, hope to help everyone know electromagnetic overflow pneumatic valve. In addition, if the overflow of the pneumatic valve itself assembly or use undeserved cause vibration, noise, so we need to pay attention in this respect.
