簡(jian)要描述：出售SMC電氣比例閥VY1系列,SMC電磁閥質量好
SMC電氣(qi)比(bi)例(li)閥在系統中(zhong)起安全(quan)保護作用。當系統壓(ya)力超過規定(ding)值時，壓(ya)力控制閥打開，將(jiang)系統中(zhong)的一部分(fen)氣(qi)體排(pai)入大氣(qi)，使系統壓(ya)力不超過允許值，從而保證系統不因壓(ya)力過高而發生事故(gu)。壓(ya)力控制閥又稱溢流閥。

出售SMC電氣比例閥VY1系列,SMC電磁閥質量好

SMC電氣比例閥結構伺服閥的主閥一般來說和換向閥一樣是滑閥結構，只不過閥芯的換向不是靠電磁鐵來推動，而是靠前置級閥輸出的液壓力來推動，這一點和電液換向閥比較相似，只不過電液換向閥的前置級閥是電磁換向閥，而比例閥的前置級閥是動態特性比較好的噴嘴擋板閥或射流管閥。也就是說，比例閥的主閥是靠前置級閥的輸出壓力來控制的，而前置級閥的壓力則來自于伺服閥的入口p，假如p口的壓力不足，前置級閥就不能輸出足夠的壓力來推動主閥芯動作。所以比例閥的閥口做得偏小，即使在閥口全開的情況下，也要有一定的壓力損失，來維持前置級閥的正常工作。
SMC電氣比例閥在系統中起安全保護作用。當系統壓力超過規定值時，壓力控制閥打開，將系統中的一部分氣體排入大氣，使系統壓力不超過允許值，從而保證系統不因壓力過高而發生事故。壓力控制閥又稱溢流閥。氣源壓力作用在活塞A上，當壓力超過由彈簧力確定的安全值時，活塞A被頂開，一部分壓縮空氣即從閥口排入大氣；當氣源壓力低于安全值時，彈簧驅動活塞下移，關閉閥口。
