1.6-Operation 操作
插入圖片
-Double acting:
Pressurized air through channel A”(NO,2,according to ISO-5559-2,POSITION1)
Displaces two opposite pistons to the end of the cylinder, transmitting by the RACK-PINION system a 90 0turn to the shaft of the actuator, provoking its OPENING,Pressurized air intirduced through channel “B”(NO.4,according to ISO-5559-2,POSITION2)reverses the movement of the two pistons,placing them to their initial position(CLOSED).
-雙作用
加壓的氣體通過講氣路A(標(biāo)號2,根據(jù)ISO-5559-2,位置1)進(jìn)入,推動(dòng)兩個(gè)相對的活塞到達(dá)氣缸左右兩端,利用齒輪齒條系統(tǒng)使執(zhí)行器軸旋轉(zhuǎn)900,使其開啟。
加壓的氣體通過氣路B(標(biāo)號4,根據(jù)ISO-5559-2,位置2)進(jìn)入,推動(dòng)活塞進(jìn)行反向運(yùn)動(dòng),回到其初始狀態(tài)(關(guān)閉)。
-Spring return:
These models contain compressed springs,situated between the capes and the pistons,The pressure made by these springs keep the pistons in POSITION2(CLOSED).Introduction of air to channel “A”(NO.2,according to ISO-559-2)
Displaces the two pistons to the ends,pressing the springs even further to POSITION 1.When the air pressure ceases,spring push the pistons to their initial position (CLOSED)Depending on the position which the actuator is mounted onto the valve,we will obtain that it works NORMALLY OPEN(N.A)or NORMALLY CLOSED(N,C.).
-單作用(彈簧復(fù)位)
這一系列執(zhí)行器內(nèi)置彈簧,至于端蓋和活塞之間,彈簧的彈力使活塞處于位置2(關(guān)閉)轉(zhuǎn)臺。加壓的氣體通過氣路A(標(biāo)號2,根據(jù)ISO-5559-2,WEIZHI 1)進(jìn)入,推動(dòng)兩個(gè)相對的活塞到達(dá)氣缸作用兩端,從而推動(dòng)彈簧到達(dá)位置1(開啟)。在失氣的情況下,彈簧的彈力推動(dòng)活塞回到初始狀態(tài)(關(guān)閉)。根據(jù)執(zhí)行器安裝在閥門的位置的不同,可以達(dá)到常開(N.A)或常閉(N.C)的工作狀態(tài)。
MOUNTING POSITION 安裝位置 | OPERATION操作狀態(tài) | |
ACTUATOR執(zhí)行器 | VALVE閥門 | |
CLOSED關(guān) | CLOSED關(guān) | N.C. 常閉 |
OPEN開 | OPEN開 | |
CLOSED 關(guān) | OPEN開 | N.A. 常開 |
OPEN 開 | CLOSED關(guān) |
