进口黄铜电磁阀 Imports of brass solenoid valve
电磁阀是用来控制流体的自动化基础元件，属于执行器；并不限于液压，气动。电磁阀用于控制液压流动方向，工厂的机械装置一般都由液压钢控制，所以就会用到电磁阀。电磁阀里有密闭的腔，在的不同位置开有通孔，每个孔都通向不同的油管，腔中间是阀，两面是两块电磁铁，哪面的磁铁线圈通电阀体就会被吸引到哪边，通过控制阀体的移动来档住或漏出不同的排油的孔，而进油孔是常开的，液压油就会进入不同的排油管，然后通过油的压力来推动油刚的活塞，活塞又带动活塞杆，活塞竿带动机械装置动。这样通过控制电磁铁的电流就控制了机械运动。
The solenoid valve is used to control the fluid automation infrastructure components belonging to the actuator; not limited to hydraulic, pneumatic. The solenoid valve is used to control the direction of hydraulic flow, the mechanism of the plant is generally controlled by hydraulic cylinder will be used solenoid valve. Solenoid valve has a closed cavity, in different positions with holes, each hole leading to the different tubing cavity intermediate valve, two-sided, two electromagnets, which face of the magnet coil is energized, the valve body will be attracted to which side, through the movement of the control valve member to file live or leaked oil discharge hole, and into the hole is normally open, the hydraulic oil will enter the discharge pipe, and then to push the oil through the pressure of the oil just pistons, piston driven piston rod, piston rod drive mechanism moving. So through the control solenoid current control of mechanical motion.
进口黄铜电磁阀形式种类：Imported brass solenoid valve in the form types
纵观国内外电磁阀，到目前为止，从动作方式上可分为三大类即：直动式、反冲式、先导式，而从阀瓣结构和材料上的不同以及原理上的区别反冲式又可分为：膜片式反冲电磁阀、活塞式反冲电磁阀；先导式又可分为：先导式膜片电磁阀、先导式活塞电磁阀；从阀座及密封材料上分又可分为：软密封电磁阀、钢性密封电磁阀、半钢性密封电磁阀。
Throughout the solenoid valve at home and abroad, far from the action mode can be divided into three categories: direct acting, recoil, pilot, and from the difference between the different structure and material of the valve as well as the principle of anti-red type can be divided into: a diaphragm type recoil electromagnetic valve, piston recoil solenoid valve; pilot type can be divided into: pilot operated diaphragm solenoid valve, pilot piston solenoid valve; seat and seal materials,can be divided into: soft seal solenoid valve, steel seal solenoid valve, semi-steel sealed solenoid valve.

性管路中的流体必须和选用的电磁阀系列型号中标定的介质*。流体的温度必须小于选用电磁阀的标定温度。电磁阀允许液体粘度一般在20CST以下，大于20CST应注明。工作压差，管路zui高压差在小于0.04MPa时应选用如直动式和分步直动式；zui低工作压差大于0.04MPa时可选用先导式压差式电磁阀；zui高工作压差应小于电磁阀的zui大标定压力；一般电磁阀都是单向工作，因此要注意是否有反压差，如有安装止回阀。流体清洁度不高时应在电磁阀前安装过滤器，一般电磁阀对介质要求清洁度要好。注意流量孔径和接管口径；电磁阀一般只有开关两位控制；条件允许请安装旁路管，便于维修；有水锤现象时要定制电磁阀的开闭时间调节。注意环境温度对电磁阀的影响电源电流和消耗功率应根据输出容量选取，电源电压一般允许±10%左右，必须注意交流起动时VA值较高。
Catheters in the fluid must be calibrated solenoid valve series models and optional media. The temperature of the fluid must be less than the selection of the calibration temperature of the solenoid valve. Solenoid valve to allow liquid viscosity general 20CST less than 20CST should be stated. Working pressure, maximum pressure pipeline in less than 0.04MPa should be chosen, such as direct-acting and step-by-step direct acting; minimum working pressure greater than 0.04MPa to use Pilot differential pressure solenoid valve; maximum working pressure difference should be less than the maximum calibrated pressure solenoid valve; general solenoid valves are one-way, so pay attention to the counter-pressure difference, if any, to install a check valve. Fluid cleanliness is not to be installed before the solenoid valve filter, general solenoid valve is better on media requirements cleanliness. Note flow aperture and take over the caliber; solenoid valve generally only switch two control; conditions permit to install a bypass pipe, ease of maintenance; custom solenoid valve opening and closing time to adjust to water hammer phenomenon. Note that the ambient temperature of the solenoid valve supply current and power consumption should be selected according to the output capacity of the supply voltage is generally allowed, attention must be about ± 10% AC starting value of VA is high.
