Rotate the handle to a certain position, so that the distance between the nozzle baffle within the scope of work, pressure reducing valve to enter the work state of the pressure chamber 5 with the nozzle and the decrease of distance between baffle increases, so promoting the spool, Open the intake valve port 9, that is, air flow to exit the same time, through the pore back to the previous chamber 4, with the pressure regulator spring balance.

將手柄旋轉到一定位置91视频人妻，使噴嘴擋板的距離在工作范圍內，減壓閥就進入工作狀態(tài)中氣室5的壓力隨噴嘴與擋板間距離的減小而增大在线观看A片免费视频，于是推動閥芯国产又粗又大在线观看，打開進氣閥口9www.BLA片，即有氣流流到出口免费视频AA在线观看，同時黄色精品视频在线观看精品免费，經(jīng)孔道反饋到上氣室4，與調壓彈簧相平衡国产欧美日韩综合精品区。

Pilot-operated pressure reducing valve is to use well in advance to adjust the air pressure instead of springs for voltage regulator, and its regulation principles and the main valve part of the structure and the same direct-acting pressure reducing valve.

先導式減壓閥是使用預先調整好壓力的空氣來代替調壓彈簧進行調壓的亚洲一区在线二区在线，其調節(jié)原理和主閥部分的結構與直動式減壓閥的相同。

Direct-action is through direct manipulation of the spring force; Pilot is a good pre-adjust the air pressure regulator instead of direct-action spring to surge, and the general flow characteristics of pilot-valve direct-acting type than good.

直動式是借助彈簧力直接操縱的国产精品15；先導式是用預先調整好的氣壓來代替直動式調壓彈簧進行調壓的18禁特黄级福利网站，一般先導式減壓閥的流量特性比直動式的好。
