一、产品简介 Product introduction

        YWK-14、YWK-14S、YWK-14T单压控制器、YWK-22、YWK-24、YWK-24S高低压控制器系列压力控制器是用来保护制冷或空调装置的制冷压缩机，使之免于吸气压力过低或排气压力过高。也可以用来启动和停止制冷压缩机或空冷冷凝器风扇。该系列压力控制器配有单刀双掷SPDT切换开关，开关位置根据压力控制器的设定值和接口处的压力而变。

        YWK-14,YWK-14S, YWK-14T single pressure controller, YWK-22, YWK-24, YWK-24S high andlow pressure controller series pressure controllers are used to protect therefrigeration compressor of refrigeration or air conditioning devices from lowsuction pressure or high discharge pressure. It can also be used to start andstop the refrigeration compressor or air-cooled condenser fan. This series ofpressure controllers is equipped with a single pole double throw SPDT switchingswitch, and the switch position varies according to the set value of thepressure controller and the pressure at the interface.

二、工作原理 Operational principle

        当被控制系统的压力升高或降低时，气箱内波纹管就压缩或伸长，通过顶杆推动开关，接通或切断电源，保证系统正确工作。

Whenthe pressure of the controlled system increases or decreases, the corrugatedpipe in the air box is compressed or extended, and the switch is pushed by thetop rod to connect or cut off the power supply, ensuring the correct operationof the system.
