age sampling meaning in English

时效抽样检验法

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 leaks , in the completion of the expansion valve assembly also undergo strict testing and fatigue resistance aging sampling , the construction expansion valves : 1 : indeed temperature temperature kits ; 2 : temperature gas or liquid filled with the expansion corrugated ; 3 : spherical valve seat ; 4 spherical valves ; 5 : spring ; 6 : overheating degrees adjustment screw spacer and screw ; 7 : internal and external ( h - type ) sealed pieces ; 8 : thrust poles and corrugated of spacer ; 9 : fati ; 10 : capillary , and so on
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。
