氣動角座閥工作原理 working principle
單作用:由一個二位三通電磁閥控制。導向介質壓力進入執行器,作用于活塞,使閥芯穿梭于閥腔中實現打開或關閉閥門。閥芯復位通常是借助于氣動執行器中的彈回彈簧來完成。
Single acting: controlled by a two position three-way solenoid valve. The pressure of guiding medium enters the actuator and acts on the piston to make the valve core shuttle in the valve chamber to open or close the valve. The valve element reset is usually completed by means of the spring in the pneumatic actuator.
1.雙向常閉(N.C.)Two way normally closed (N.C.)介質從閥芯下方流入,可避免水錘作用。介質在閥芯上方流入,將受到水錘擠壓;
The medium flows under the valve core to avoid the action of water hammer. If the medium flows above the valve core, it will be squeezed by water hammer;
常閉型(N.C.)介質從閥芯上方流入,介質從閥芯上方流入會造成"水錘"效應Normally closed (N.C.) medium flows from above the valve core, which will cause "water hammer" effect
常開型(N.O.)介質從閥芯下方流入Normally open (N.O.) medium flows from below the valve core
雙作用:配置的閥門中,沒有彈回彈簧,導向介質既用來打開閥門,也用來關閉閥門。
Double acting: there is no spring in the configured valve, and the guiding medium is used to open and close the valve.

適用介質范圍
閥門的最小工作壓力是根據閥門的型號和腔內流體壓力的峰值差異確定的,由此也可確定對應閥門的型號。空氣、水、酒精、油、石油燃料油、鹽溶液、蒸汽等(所有適用于 AISI304、316不銹鋼或青銅 RG5 的流體介質);按所選型號和運行參數,閥門的工作壓力應位于 0~16/25Bar ,(蒸汽介質在 180℃C時,工作壓力為0~10 Bar)
介質溫度∶ -10℃ ~180℃
介質粘度∶≤600cst(mm2/s)
The minimum working pressure of the valve is determined according to the model of the valve and the peak difference of the fluid pressure in the cavity, so the model of the corresponding valve can also be determined. Air, water, alcohol, oil, petroleum fuel oil, salt solution, steam, etc. (all fluid media suitable for AISI304, 316 stainless steel or bronze Rg5); According to the selected model and operating parameters, the working pressure of the valve should be 0~16/25bar (when the steam medium is 180 ℃, the working pressure is 0~10 bar)
Medium temperature: -10 ℃ ~180 ℃
Maximum viscosity of medium: 600cst (mm 2/ s)

"水錘效應"是指在水管內部,管內壁光滑,水流動自如。當打開的閥門突然關閉,水流對閥門及管壁,主要是閥門會產生一個壓力。由于管壁光滑,后續水流在慣性的作用下,迅速達到最大,并產生破壞作用,這就是水力學當中的"水錘效應"。也就是正水錘。在水力管道建設中都要考慮這一因素。相反,關閉的閥門在突然打開后,也會產生水錘.叫負水錘,也有一定的破壞力.但沒有前者大。
"Water hammer effect" means that inside the water pipe, the inner wall of the pipe is smooth and the water flows freely. When the open valve suddenly closes, the water flow will produce a pressure on the valve and pipe wall, mainly the valve. Because the pipe wall is smooth, the subsequent water flow quickly reaches the maximum under the action of inertia, and has a destructive effect, which is the "water hammer effect" in hydraulics. That is, positive water hammer. This factor should be considered in the construction of hydraulic pipelines. On the contrary, water hammer will also occur when the closed valve is suddenly opened Called negative water hammer, it also has certain destructive power But not as big as the former.
