Needle valves are non-compensating devices the orifice sige will regu late the flow through the valve in proportion to the sgure root of the pressure differential across port 1 and 2,therefore naking these valves suitable only where the load remains constant.

依赖它们在回路中的位置可作量入，量出，旁伸控制。●孔口流量正比压降平主根因此只适合固定负载，变动负载要用压力补偿阀。

Electronic expansion valve stepper motor is based on changes in the evaporator outlet pressure P1, the compressor suction Plug Valves superheat degree change in real-time changes in power output, the real-time output of the dynamics of change in time to overcome a variety of working conditions and the main expansion of load condition valve spring force changes, so that the valve opening to meet the evaporator, the demand Reducing Valves for fluid volume and thus the amount of fluid for the evaporator and the evaporator load in real-time match, that is, the electronic expansion valve can be set through the controller, man-made and effective control over superheat.

电子膨胀阀的步进电机是根据蒸发器出口压力P1变化、压缩机吸气过热度变化实时输出变化的动力，这个实时输出变化的动力能及时克服各种工况和各种负荷情况下主膨胀阀变化的弹簧力，使阀的开度满足蒸发器供液量的需求，进而蒸发器的供液量能实时与蒸发负荷相匹配，即电子膨胀阀可通过控制器人为设定，有效的控制过热度。

Pressure governor valve is the use of a spring-loaded power and pressure balance theory, when the spring-loaded pressure less than atmospheric pressure and the valves closed when the pressure is greater than the spring-loaded rubber tubing stretch when the bottom of compressed air diaphragm, diaphragm the effort to promote diaphragm upward and left vavle seat blow the air flow of gas, this would piston shirking role in the pressure mobile, Selection will be emissions from valve seat, air compressors made by the then air into the gas valves and exhaust emissions is through the mouth into atmospheric air compressors idling.

调压阀的原理是利用了弹簧力与压力相平衡的原理，当弹簧的压力小于气压的时候阀关闭，当压力大于弹簧的弹力时候橡胶调压膜片下方的压缩空气对膜片的用途力，推动膜片向上拱曲离开阀座而使空气流入气腔，此时卸荷活塞在气压用途下移动，将排放阀门推离阀座，于是由空气压缩机充入气腔的空气便通过排放阀和排气口排入大气空气压缩机空转。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
