Pilot operated solenoid valve
Principle: When powered on, electromagnetic force opens the pilot hole, causing the pressure in the upper chamber to rapidly decrease. This creates a pressure difference of high and low around the closing element, pushing it upwards and opening the valve; When the power is cut off, the spring force closes the pilot hole, and the inlet pressure quickly enters the upper chamber through the bypass hole, forming a pressure difference of lower and higher around the closing valve, pushing the closing valve to move downward and close the valve.
Characteristic: The upper limit of fluid pressure range is very high, but it must meet the condition of fluid pressure difference.
At present, there are more than ten varieties of commonly used solenoid valves sold in China, including DV (DVF), PGA, PEB (PESB), BPE series, with diameters ranging from 3/4 "to 3", mainly used in agriculture, landscaping, golf, industrial dust prevention and fountain fields. The commonly used solenoid valve is a diaphragm valve, which works by dividing the valve body into upper and lower chambers with a diaphragm in the middle. Under the same water pressure, a pressure difference is generated due to the different force areas on the diaphragm, achieving the purpose of cutting off the water flow.
Electromagnetic valve open state - When an electrical signal is given through a remote controller or the electromagnetic head is manually rotated, the drainage channel is opened, the water in the upper diaphragm chamber is discharged, the indoor pressure decreases, and the pressure acting on the upper diaphragm decreases. Under the action of upstream pressure, the diaphragm is pushed upward to open the pipeline channel.
Electromagnetic valve closed state - manually close or disconnect the electromagnetic head electrical signal to close the drainage channel, slowly fill the upper diaphragm chamber with water, and wait until the pressure on the upper and lower sides of the diaphragm is consistent. Due to the large force area on the upper side of the diaphragm, the diaphragm moves downward and closes the pipeline channel.
Single electronic control only has one solenoid head. After being powered on, the solenoid valve changes direction. After losing power, the solenoid valve resets due to the action of the spring. Dual electronic control 2-position solenoid valve has two solenoid heads, only one of which can be powered on. After being powered on, the solenoid valve changes direction. After losing power, the solenoid valve remains in position. The other solenoid head must be powered on before the solenoid valve returns to its original position.

The goal of valve manufacturing using SMC solenoid valve sealing technology to prevent valve leakage is to design a secure valve stem sealing method to meet emission guidelines. The area between the outer sealing stem and the valve cap of the valve. The packaging material is usually polytetrafluoroethylene, designed in different arrangements to reduce the relaxation and mechanical damage of carbon or graphite to cycles and time. The use of this ammunition force is often a way to reduce loose packaging groups.

The use of SMC solenoid valve sealing technology to prevent valve leakage is due to the result of packaging no-load loss and increased leakage relaxation. The key limitation of tightening the gland follower or liner of excessive packaging is the radial expansion of the packaging, which increases packaging wear and restricts dry movement, thereby also limiting emissions reduction.

In addition to pneumatic leak detection, the valve stem packaging system and metal bellows sealing can be used to reduce valve stem leakage. Although packaging has been developed over the years to meet tight leakage requirements, it has always represented the sealing technology between metal corrugated pipes.

The lifespan of corrugated pipe seals far exceeds even packaging that can achieve zero leakage. In the past, health and safety concerns were important in the critical application of this zero stem leakage method, and it was reasonable to consider the use of wooden to high corrugated tubes. However, in this metal corrugated pipe technology, the risks to health, safety, and the environment should also be considered to justify the use of any application in existing * technology solutions.

The internal structure diagram of the corrugated tube sealed SMC solenoid valve may be affected by external factors that affect its service life, including the selection of suitable materials for construction, suitable design methods for implementation, manufacturing processes used, consideration of the sealing that will face adversity, and the impact of the process medium on the sealing. Metal bellows are typically constructed with high-strength austenitic stainless steel or similar corrosion-resistant nickel based alloys.

After the specifications of the SMC solenoid valve are determined, its control torque is also determined. When it operates within a predetermined time, the motor generally does not experience any load.

1. SMC solenoid valve power supply voltage is low, unable to obtain the required torque. Stop the motor from rotating.

2. The torque limiting mechanism was incorrectly set to exceed the stopping torque, resulting in continuous excessive torque and causing the motor to stop rotating.

3. Intermittent use like jogging, the heat generated accumulates and exceeds the allowable temperature rise of the motor.

4. Due to some reason, the torque limiting mechanism circuit has malfunctioned, resulting in excessive torque.

5. The high ambient temperature during use can cause a relative decrease in the thermal capacity of the motor. These are some of the reasons for the occurrence of load, and the phenomenon of motor overheating caused by these reasons should be considered in advance, and measures should be taken to prevent overheating. In the past, the methods for protecting motors included using fuses, overcurrent maintenance devices, thermal maintenance devices, thermostats, etc. However, each of these methods has its own advantages and disadvantages. For electric devices with variable loads, reliable protection methods are not available. Therefore, it is necessary to adopt a combination of various methods. However, due to the different load conditions of each electric device, it is difficult to propose a unified solution. But in most cases, commonalities can also be found.
