Because expansion valves are high precision processing components,factory in its internal adjustment of the body parts are processed in a state of complete thermostatic, the temperature of the gas filling kits are demanding more consistent not detect leak

因为膨胀阀是属于超高精密加工的零件，在工厂对其内部调整机构零件的加工都在恒温状态下完成，其中的感温包的气体充填更是要求严格一致不允许一丝泄漏，在完成装配的膨胀阀还要经过严格的测试和耐疲劳老化抽检，膨胀阀的构造：1：感知温度的感温包；2：感温气体或者液体充填膨胀波纹腔；3：球型阀座；4球型阀；5：弹簧；6：过热度调整螺丝垫片和螺丝；7：内部和外部（H型）密封件；8：推力杆和波纹腔垫片；9：阀体；10：毛细管等等。
