YK系列超高压自动复位 压力控制器(CO2冷媒用) Product Specifications 产品特点 ◆ Adopt Eng. thread quick connector (copper flare connection) or brass tube welding structure, easy to use and no special installing requirement. ◆ Plugging or wiring connection designed to customers’choice. ◆ Single cut single thrower switch mode and normal open structure.. ◆ Security and reliability by adopting fusion welding stainless steel pressure inductor covered by burst-proof outer shell made of steel. ◆ Any pressure value within 1305PSI~2610PSI (9~18MPa) can be made based on customers' requirement. ◆ Pre-set pressure parameter before delivery allows direct use without resetting on the customers' site. ◆ 采用英制管螺纹快速接头或铜管焊接式结构，使用方便，安装灵活，无需特殊的安装固定； ◆ 插片式或导线式连接方式可供用户任意选择； ◆ 单刀单掷型开关方式，常开式开关接点结构； ◆ 熔焊密封式不锈钢压力感应器外加钢制防爆外壳，安全可靠； ◆ 在1305PSI~2610PSI(9～18MPa)压力范围内可根据用户要求任意选定压力值进行制造； ◆ 产品在出厂前其压力参数在工厂已按要求设定好，无需再设定，可直接使用； Typical Outline Drawing 典型外形图 Operating Principle 工作原理 ◆ The series of pressure control are made based on the theory that an inside reversible stainless steel motion diaphragm turns over when inducing certain pressure. The electric contact opens with the leader when the diaphragm moves. The switch resets automatically when induced pressure reduces below rated value. ◆ 该系列压力开关主要利用内置的不锈钢可翻转动作膜片在感应到一定压力后可向反方向翻转的特性进行制造。当膜片动作时，会通过一个导杆带动电气触点的打 开。当在感应压力降低至恢复值以下时，压力开关即可自动复位。 Typical Structure Drawing 典型结构图 Designed Parameter 设计参数 ◆ Working pressure range: 1305-2610PSI(9~18MPa) ◆ Burst Pressure: 10440PSI(72MPa) ◆ Ambient temperature: -30℃~+80℃ ◆ System medium temperature: -50℃~+120℃ ◆ Electrical Rating: At 24Vac, normal electric capacity: 125VA At 120/240Vac, normal electric capacity: 375VA ◆ Dielectric Strength: Between disconnected contacts: AC700V/S Terminal to outer shell: AC2000V/S ◆ 工作压力范围：1305~2610PSI(9～18MPa) ◆ 爆破压力：10440PSI(72MPa) ◆ 环境温度：-30℃～+80℃ ◆ 系统介质温度：-50℃～+120℃ ◆ 电气规格： 24Vac时常规电气容量125VA 120/240Vac时常规电气容量375VA ◆ 抗电强度：断开触点间为AC700V/S，端子对外壳为AC2000V/S Application 用途 ◆ The series of products are specially designed and manufactured for the refrigeration equipment using CO2 as refrigerant, the pressure of this kind of refrigeration system is much higher than that of the normal system. The product also applies to all equipments and toolings with the high protection pressure over 800PSI(5.5 MPa). ◆ 该系列产品是专门针对使用二氧化碳作为制冷剂的制冷设备，其制冷系统压力大大高于常规制冷剂压力的特殊要求而设计制造，用于系统的高压保护；同时也适 用于各类系统高压保护压力大于800PSI(5.5MPa)的设备及工具。 C H Normal close 常闭型 Electric Theory Drawing 电气原理图 YK Series Extra-High Pressure Auto-reset Pressure Control 9 8
