Compression couplings with ball - type nipples - complete unions and survey 帶球形襯套的壓接接頭.完整接頭和概述
Gland : gland is a two - piece ball - type which exerts even pressure on the packing without binding the stem 壓蓋:壓蓋為兩件式球形結(jié)構(gòu),將壓力均勻地施加在填料上,不會(huì)造成閥桿彎曲。

When the temperature to gas pipelines , temperature packets of material expansion , the pressure rise , inflation pressures are rising corrugated box , corrugated promote the expansion thrust to overcome the spring - loaded pole resistance , the ball - type valve opened for big change ; when the gas pipeline to reduce the temperature , temperature of the material swelling up , the pressure lowered inflation corrugated box pressure also reduced , spring - loaded pole compressed corrugated of resistance to thrust , spherical valves open for smaller ; this constant push and pull adjustment for the balance , as long as refrigeration cycle continue 當(dāng)回氣管道溫度升高,感溫包內(nèi)的物質(zhì)膨脹,壓力升高,膨脹波紋箱內(nèi)壓力也升高,波紋腔膨脹推動(dòng)推力桿克服彈簧阻力,球型閥開度變大;當(dāng)回氣管道溫度減低,感溫包內(nèi)的物質(zhì)膨脹,壓力降低,膨脹波紋箱內(nèi)壓力也降低,彈簧阻力推動(dòng)推力桿壓縮波紋腔,球型閥開度變小;如此不斷的進(jìn)行推拉調(diào)整平衡,只要制冷循環(huán)繼續(xù)下去。
Temperature kits : contact must be properly fixed in the evaporator export pipelines , real - time communication evaporator components to temperature degrees , the material will be filled through interlinked capillary pressure due to the expansion of corrugated boxes ; swelling corrugated boxes on the pressure for change in the thrust pole with an adjustment screw and spring - loaded ball - type valves to adjust the resistance of the degrees of refrigeration volume precision adjustments 感溫包:是必須妥善接觸固定在蒸發(fā)器的出口管道上,感知蒸發(fā)器實(shí)時(shí)回氣溫度的部件,它將充填物質(zhì)的熱脹冷縮壓力通過相通的毛細(xì)管提供給膨脹波紋箱;膨脹波紋箱依據(jù)壓力的變化推動(dòng)推力桿結(jié)合過熱度調(diào)整螺絲和彈簧的阻力來調(diào)整球型閥的開度,實(shí)現(xiàn)制冷量的精確調(diào)整。
