高压电磁阀产品介绍:

高压电磁阀作为自动化控制领域的关键元件，在众多复杂且严苛的工况中发挥着至关重要的作用。其性能和质量，使其成为各类高精度控制场景的理想选择。

高压电磁阀产品结构与特点：

（一）结构类型.高压电磁阀分为直动式和先导式两种结构原理。直动式结构简单，在一些小口径、对响应速度要求极高的场合表现出色，能迅速对电信号做出反应，实现阀门的开启与关闭。先导式则适用于较大口径及更高压力的环境，通过先导阀芯控制主阀的动作，利用介质压力差实现、稳定的运行。

（二）采用先导膜片式或活塞式结构，可承受高达 50 巴甚至更高的压力（部分特制产品压力可突破 300MPa）。整体设计紧凑，外观精美，占用空间小，便于在各类空间有限的设备中安装。运行时温升低，有效减少了因发热导致的性能衰减和安全隐患；并且运行过程安静无噪音，不会对工作环境造成干扰。通过三维密封结构，搭配多种可选择的密封材质，实现了阀门的零泄漏效果，确保介质传输的安全性和稳定性。动作响应速度极快，频率高，能够在短时间内多次开启和关闭，满足复杂控制逻辑下对阀门快速动作的需求，可在长时间、高频率的工作状态下稳定运行，减少维护频次。

高压电磁阀工作原理:

（一）常闭状态:当线圈通电时，产生的电磁力吸引先导阀芯打开先导孔，阀上腔内的压力迅速释放。此时，主阀活塞在介质压力的推动下，克服弹簧力等阻力，向上移动打开主阀口，介质开始流通。当线圈断电时，先导阀芯在弹簧的作用下复位，关闭先导孔。阀上腔内部压力因介质无法排出而逐渐升高，在压力差和弹簧力的共同作用下，主阀活塞向下移动，关闭主阀口，介质截止。

（二）常开状态:与常闭状态相反，当线圈通电时，电磁力使先导阀芯动作关闭先导孔，阀上腔内部压力逐渐升高。同时，复位弹簧推动主阀活塞向下移动，关闭主阀口，介质停止流通。当线圈断电时，先导阀芯依靠弹簧复位，先导孔打开，阀上腔内的压力得以释放。主阀活塞在介质压力的推动下向上移动，打开主阀口，介质恢复流通。

高压电磁阀技术规格:

Introduction to High-Pressure Solenoid Valves

As a key component in the field of automated control, high-pressure solenoid valves play a crucial role in numerous complex demanding working conditions. Their superior performance reliable quality make them an ideal choice for various high-precision control scenarios.

I. Product Structure Characteristics

(I) Structural Types

High-pressure solenoid valves are categorized into two structural principles: direct-acting pilot-operated. The direct-acting type features a simple structure excels in applications with small diameters extremely high requirements for response speed. It can quickly react to electrical signals to open close the valve. The pilot-operated type is suitable for environments with larger diameters higher pressures. It controls the action of the main valve through the pilot valve core, achieving efficient stable operation by utilizing the pressure difference of the medium.

(II) Structural Features

Adopting a pilot diaphragm piston structure, these valves can withstand pressures of up to 50 bar even higher (some special products can withstand pressures exceeding 300MPa). With a compact design an elegant appearance, they occupy minimal space, facilitating installation in various equipment with limited space. During operation, the temperature rise is low, effectively reducing performance degradation potential safety hazards caused by heat generation. Additionally, their operation is quiet noiseless, ensuring no interference with the working environment. Thanks to the advanced three-dimensional sealing structure a variety of selectable sealing materials, these valves achieve zero leakage, ensuring the safety stability of medium transmission. They offer extremely fast response speeds high action frequencies, enabling multiple openings closings in a short time to meet the requirements of rapid valve actions in complex control logics. With high reliability, they can operate stably under long-term high-frequency working conditions, reducing maintenance frequency.

II. Working Principles

(I) Normally Closed State

When the coil is energized, the generated electromagnetic force attracts the pilot valve core to open the pilot hole, rapidly releasing the pressure in the upper valve chamber. At this time, the main valve piston moves upward under the push of the medium pressure, overcoming resistance such as spring force, opens the main valve port, allowing the medium to flow. When the coil is de-energized, the pilot valve core resets under the action of the spring closes the pilot hole. The internal pressure of the upper valve chamber gradually increases as the medium cannot be discharged. Under the combined action of the pressure difference spring force, the main valve piston moves downward to close the main valve port, stopping the medium flow.

(II) Normally Open State

Contrary to the normally closed state, when the coil is energized, the electromagnetic force causes the pilot valve core to close the pilot hole, gradually increasing the internal pressure of the upper valve chamber. Meanwhile, the reset spring pushes the main valve piston downward to close the main valve port, halting the medium flow. When the coil is de-energized, the pilot valve core resets under the action of the spring, opening the pilot hole releasing the pressure in the upper valve chamber. The main valve piston moves upward under the push of the medium pressure, reopening the main valve port resuming the medium flow.

The internal thread connection is suitable for small-diameter valves, featuring easy installation good sealing performance. The flange connection is suitable for large-diameter high-pressure applications, providing a firm connection reliable sealing. Customized connection methods can meet the installation requirements of special equipment pipelines, ensuring a perfect match between the valve the system.

(X) Leakage Rate

V. Installation Precautions

1. Before installation,      carefully read the product instruction manual to fully understand the      product's performance parameters, working principles, installation      requirements, ensuring that the product meets the actual usage needs.

2. Thoroughly clean the pipeline to be connected, removing      impurities, dirt, rust, etc. inside the pipeline to prevent these      impurities entering the solenoid valve affecting the normal      operation sealing performance of the valve. If the medium is      clean, install a filter with an appropriate precision at the front end of      the solenoid valve, regularly clean maintain the filter to ensure      its filtering effect.

3. For solenoid valves that have been used for a long time,      before reactivation, remove any accumulated condensate, impurities, etc.      inside. This can be done by blowing with compressed air disassembling       cleaning. When disassembling cleaning, pay attention to recording      the installation order of each component to avoid errors during      reassembly.

4. High-pressure solenoid valves are generally one-way working      valves. During installation, strictly ensure that the arrow direction      marked on the valve body is consistent with the actual flow direction of      the fluid in the pipeline. Otherwise, the valve will operate normally       may even be damaged.

5. If the solenoid valve is installed in an environment      icing may occur, before putting it back into use, appropriately heat the      solenoid valve, such as by using electric tracing, steam heating, etc.,      take reliable insulation measures to prevent the medium inside the valve       freezing damaging the valve.

6. It is recommended to keep the valve body in a horizontal      position with the coil facing upward during installation. This      installation method helps to extend the service life of the solenoid valve       ensures the normal movement lubrication of the internal components      of the valve. Although some valve models allow arbitrary installation,      following this installation posture can achieve better usage results when      conditions permit.

7. After connecting the lead wires (connectors) of the      electromagnetic coil, carefully check whether the connection is firm to      ensure good contact. Avoid poor contact caused by loose connections, which      may lead to abnormal operation unstable performance of the solenoid      valve. For applications that require continuous production, to avoid      affecting production in case of solenoid valve failure, it is recommended      to set up bypass pipelines valves near the solenoid valve. This allows      the system to continue operating through the bypass during solenoid valve      maintenance.
