School integration of automated electrical mechanical little friends probably solenoid valve are very familiar with, there are many types of solenoid valves, commonly used is two-way and three-way solenoid valve, Xiao Bian recently received messages often have friends like Xiaobian inquires about the difference between the two-way solenoid valve and the three-way solenoid valve, because there are more people asking this question, so Xiaobian wrote a separate article today to introduce to you carefully what the solenoid valve is and two. The difference between the solenoid valve and the three-way solenoid valve, please come and see with the decoration home network Xiaobian, I hope this article can bring you some help and reference, let us one Get up and have a look!
In fact, the two-way solenoid valve is a straight-through switch valve. Just like a normal valve, it is only divided into manual electric and pneumatic. The solenoid valve we are talking about is electric (usually the instrument solenoid valve, 24V, the usual meaning of the electric valve. It should be the mains, 220V, the two kinds of difference), but we must be clear, it is two-digit, so it can only be fully open or closed. This can be seen on the fuel line of some auto-ignited igniters.
The two-position two-way solenoid valve is mainly used on the on-off valve. The two positions have two positions "on" and "off". In fact, the solenoid valve is powered and de-energized. The valve to be controlled is a FO valve or a FC valve, and the two-way solenoid valve has two passages, one air inlet and one air outlet.
The two three-purpose are on the pneumatic regulating valve, one facing the cylinder or the membrane head (one pass A), one facing the wind source or the atmosphere (two passes P, T), or the cylinder and the gas source (supply air), or the cylinder It is connected to the atmosphere (the two-position three-way solenoid valve is used on the valve positioner on the regulating valve to adjust the opening of the valve. The difference between the two-way solenoid valve is that it has three ports, one out The air port has an air inlet and an air inlet, and the opening amount of the valve is controlled by the amount of the air intake.
There is also a pressure relay. In fact, the pressure relay is a contact switch. If it is lower than the set value, it will not be triggered. If it is higher than the set value, it will trigger immediately, just like a simple small interlock. For example, a pneumatic clutch on a rod mill that uses a similar pressure switch to control the pressure of the buffer tank, so when the pressure is lower than the set value, the air compressor is automatically started, when it is higher than the set value. The air pressure opportunity stops automatically.
The above is the introduction of the two-way solenoid valve and the three-way solenoid valve brought to you by the decoration home network Xiaobian. I hope that I can bring some help to you. I wonder if everyone is satisfied with the introduction of Xiaobian? If you still need more information, please continue to pay attention to our home encyclopedia!
