Mini Solenoid Valve 3.7v Pressure Regulating Valve

What are the types and functions of solenoid valves?

Solenoid Valve is an actuator that uses electromagnetic principles to control the on-off, flow direction, flow, pressure and speed of fluids (such as water, air, steam, etc.). It belongs to the electric valve category among actuators. Its main types and functions are as follows:

type:

1. Direct-acting solenoid valve: The principle is that when the power is on, the solenoid coil generates electromagnetic force to lift the closing member from the valve seat, and the valve opens; when the power is off, the electromagnetic force disappears, and the spring presses the closing member against the valve seat, and the valve closes. .

2. Step-by-step direct-acting solenoid valve: This valve uses one-time valve opening and two-time valve opening connected together. The main valve and pilot valve use electromagnetic force and pressure difference to directly open the main valve port step by step.

3. Indirect pilot solenoid valve: The principle is that when power is applied, the electromagnetic force opens the pilot hole, and the pressure in the upper chamber drops rapidly, forming an upper, lower, and higher pressure difference around the closing member. The fluid pressure pushes the closing member to move upward, and the valve opens; When the power is off, the spring force closes the pilot hole, and the inlet pressure quickly flows through the bypass hole into the chamber to form a lower pressure difference and a higher pressure around the valve closing member. The fluid pressure pushes the closing member downward to close the valve.

Function:

The solenoid valve mainly controls the direction, flow rate, speed and other parameters of the fluid, thereby realizing the regulation and control of mechanical movement, production process, etc. It has the advantages of simple structure, fast and reliable action, small size, light weight, convenient operation and easy maintenance, and can be controlled by multi-bit switch or proportional quantity.

What is a one-way solenoid valve?

One-way solenoid valve is a device that controls the attraction and disconnection of an electromagnet through gas pressure to control gas flow. It consists of solenoid coil and valve body.

When the solenoid coil is energized, it generates a magnetic field that attracts or pushes away the magnetic piston in the valve body. There is a sealing ring between the magnetic piston and the valve body. When the magnetic piston moves, the sealing ring can prevent the flow of fluid or allow the flow of fluid. By controlling the power-on and power-off status of the solenoid coil, the solenoid valve can be controlled to adjust the flow and direction of the fluid.

One-way solenoid valves are widely used in many fields, including medical electronics, fluid control, maternal and infant products, household appliances, etc. Its control principle is simple and easy to use, providing reliable technical support for production companies to improve efficiency and reduce costs.

Technical Specification

What is the difference between a micro solenoid gas valve and a micro Solenoid Water Valve?

There are several main differences in the design and application of micro solenoid gas valves and micro solenoid water valves:

1. Medium applicability: Micro solenoid gas valves are mainly used to control gas media. Their design and material selection take into account the characteristics of the gas, such as compressibility, fluidity, etc. The miniature solenoid water valve is specially designed for liquid media, especially water or other liquid substances. Factors such as the pressure, viscosity and possible corrosiveness of the liquid need to be taken into consideration.

2. Sealing requirements: Due to the different physical properties of gases and liquids, the requirements for sealing performance are also different. Gases are usually more likely to leak, so miniature solenoid valves may have higher sealing performance requirements. Although miniature solenoid water valves also require good sealing, they may pay more attention to corrosion resistance to deal with impurities that may be present in the liquid.

3. Structure and materials: In order to cope with different media and working environments, the structure and material selection of micro solenoid air valves and micro solenoid water valves may also be different.

For example, gas valves may require lighter materials to reduce friction and energy consumption during operation, while liquid valves may require materials that are more resistant to corrosion.

What is the difference in control accuracy between micro solenoid air valves and micro solenoid water valves?

The difference in control accuracy between micro solenoid gas valves and micro solenoid water valves mainly depends on their respective working medium characteristics and design requirements.

First of all, due to the fast flow speed of gas, miniature solenoid gas valves usually have a high response speed. Therefore, in theory, the control accuracy of the gas valve may be higher in situations where fast response is required. At the same time, pressure and flow changes in gas pipelines may be rapid and complex, so gas valves need to have higher control accuracy to meet stability requirements.

However, for miniature solenoid water valves, the flow speed of water is relatively slow, which may affect its response speed. But water valves may have their own unique advantages in controlling liquid flow and pressure. Liquid flow is generally more stable, so water valves may exhibit greater control accuracy in certain applications where precise control of flow is required.

In addition, the control accuracy is also affected by the design, manufacturing process and control system of the solenoid valve itself. High-quality solenoid valves generally have more precise control capabilities, whether for gases or liquids. Therefore, when comparing the control accuracy of the two, it is also necessary to consider the performance parameters and technical indicators of the specific product.

How to reduce the impact on the performance of the solenoid valve while ensuring control accuracy?

2. Optimize the control system: Optimizing the control system can improve the control accuracy of the solenoid valve. For example, advanced control algorithms (such as PID control, fuzzy control, etc.) are used to accurately control the switching state of the solenoid valve to achieve more precise control effects.

3. Reduce electromagnetic interference: The solenoid valve may produce electromagnetic interference during operation, affecting control accuracy. Therefore, measures can be taken to reduce electromagnetic interference, such as using magnetic metal and grounding for electromagnetic shielding, and optimizing the driving method of solenoid valves.

4. Use the appropriate medium: For liquid solenoid valves, choosing the appropriate liquid medium can also reduce the impact on the performance of the solenoid valve. For example, avoid using liquids that contain impurities or are corrosive to reduce wear and corrosion on the solenoid valve.

6. Reasonable design of the piping system: Reasonable design of the piping system can reduce the impact and vibration of the fluid on the solenoid valve, thereby reducing the impact on the performance of the solenoid valve. For example, measures such as buffer devices and shock-absorbing devices are used to reduce vibration and noise in the pipeline system.
