一、电磁阀的特性 1质气，液态或混合状态分别选用不同品种的电磁阀，例ZQDF用于空气，ZQDF—Y用于液体，ZQDF—2（或-3）用于蒸汽，否则易引起误动作。ZDF系列多功能电磁阀则可通通于气.液体。{zh0}订时告明介质状态，安装用户就不必再调式。 2介质温度不同规格产品，否则线圈会烧掉，密封件老化，严重影响寿命命。 3介质粘度，通常在50cSt以下。若超过此值，通径大于15mm用ZDF系列多功能电磁阀作特殊订货。通径小于15mm订高粘度电磁阀。 4介质清洁度不高时都应在电磁阀前配装反冲过滤阀，压力低时尚可选用直动膜片式电磁阀作例如CD—P。 5介质若是定向流通，且不允许倒流ZDF—N和ZQDF—N单需用双向流通，请作特殊要求提出。 6介质温度应选在电磁阀允许范围之内。 二.管道参数 1根据介质流向要求及管道连接方式选择阀门通口及型号。例如，用于一条管道向两条管道切换的，小通径的选CA5和Z3F，中等或大通径请选ZDF—Z1/2。又如控制两条管道汇流的，请选ZDF—Z2/1等。 2根据流量和阀门Kv值选定公称通径，也可选同管道内径。请注意有的厂家未标有Kv值，往往阀孔尺寸小于接口管径，切不可贪图价低而误事。 3工作压差 {zd1}工作压差在0.04Mpa以上是可选用间接先导式；{zd1}工作压差接近或小于零的必须选用直动式或分步直接式。 三.环境条件 1环境的{zg}和{zd1}温度应选在允许范围之内，如有超差需作特殊订货提出。 2环境中相对湿度高及有水滴雨淋等场合，应选防水电磁阀。 3环境中经常有振动，颠簸和冲击等场合应选特殊品种，例如船用电磁阀。 4在有腐蚀性或爆炸性环境中的使用应优先根据安全性要求选用耐发蚀。 5环境空间若受限制，请选用多功能电磁阀，因其省去了旁路及三只手动阀且便于在线维修。 四.电源条件 1根据供电电源种类，分别选用交流和直流电磁阀。一般来说交流电源取用方便。 2电压规格用尽量优先选用AC220V.DC24V。 3电源电压波动通常交流选用+%10%.-15%，直流允许±%10左右，如若超差，须采取稳压措施或提出特殊订货要求。 4应根据电源容量选择额定电流和消耗功率。须注意交流起动时VA值较高，在容量不足时应优先选用间接导式电磁阀。 五.控制精度 1普通电磁阀只有开、关两个位置，在控制精度要求高和参数要求平稳时请选用多位电磁阀；Z3CF三位常开电磁阀，具有微启，全开和关闭三种流量； ZDF—Z1/1组合多功能电磁阀具有全开、大开、小开、全开四种流量。 2动作时间：指电信号接通或切断至主阀动作完成时间，只有本公司专利产品多功能电磁阀可对开启和关闭时间分别调节，不仅可满足控制精度要求，还可防止水锤破坏。

First, the characteristics of electromagnetic valve A quality of gas, liquid or mixed states, which are used in different varieties of solenoid valves, patients ZQDF for air, ZQDF-Y for liquid, ZQDF-2 (or -3) for the steam, otherwise easily lead to malfunction. ZDF Series multi-function solenoid valve can be them altogether in the air. Liquid. Report set out the best when the state media, the user will not have to install the debugging. 2 medium temperature products of different specifications, otherwise the coil will burn, seals aging, seriously affect the life of life. 3 medium viscosity, usually 50cSt the following. If more than this value, greater than 15mm diameter with ZDF series multi-function valve for special order. Diameter less than 15mm high viscosity valve set. 4 medium cleanliness is not high when the solenoid valve should be installed before the recoil filter with valve, low pressure style can be used direct-acting diaphragm solenoid valves for example, CD-P. 5 If the directional flow of media, and are not allowed back ZDF-N and ZQDF-N single Xu Yong-way flow, please make a special request. 6 medium temperature should be chosen within the allowable range of electromagnetic valve. 2. Pipeline parameters 1 According to the medium flow pipe connection requirements and select the valve openings and model. For example, for a pipeline to switch to the two pipelines, with a small diameter of the election CA5 and Z3F, medium or large diameter, please select ZDF-Z1 / 2. Another example is control of the convergence of the two channels, select ZDF-Z2 / 1 and so on. 2 According to the value of selected flow and valve Kv nominal diameter, pipe diameter is also optional with. Please note that some manufacturers are not marked with the Kv value, often less than the interface, valve hole size diameter, must not seek the lowest and makes a botch. 3 Working pressure Minimum working pressure is more than can be used in 0.04Mpa indirect Pilot; minimum working pressure close to or less than zero must be selected direct-action direct-type or sub-step. 3. Environmental conditions An environment of maximum and minimum temperature should be selected within the allowable range, if tolerance required for special order made. 2 environment relative humidity is high and there are water droplets rain and so on, should be selected water solenoid valve. 3 environment often vibration, bumps and shocks should choose special varieties of occasions, such as marine solenoid valve. 4 in a corrosive or explosive environment, the use of security requirements should be given priority selection under the anti-hair loss. 5, if the restricted environmental space, please use the multi-function valve, because eliminating the manual bypass and the three valves and easy online service. 4. Power conditions 1 According to the power supply types were selected to AC and DC solenoid valves. Generally speaking, convenient access to AC power. 2 voltage specifications used as preferred AC220V.DC24V. 3 AC power supply voltage fluctuations are usually used +% 10% .- 15%, DC to allow ±% 10 or so, should the ultra-poor, to take measures or make a special order regulator requirements. 4 Select the rated power capacity should be based on current and power consumption. VA should be noted that when the exchange value of the higher start, lack of capacity should be preferred in the indirect electromagnetic valve guide. 5. Control accuracy A common solenoid valve only opening and closing two locations, high precision in the control and parameters for a smooth, please choose a number of solenoid valves; Z3CF three normally open solenoid valve, with Weiqi, fully open and close the three kinds of traffic; ZDF-Z1 / 1 combination of multi-function valve with open, wide open, small open, open all four types of traffic. 2 movement time: that signal through or cut off from the main valve action completion time, only the company's patented multi-function valve can open and close time were adjusted to meet the control of not only precision, but also to prevent water hammer damage.
