閘閥 美國A＆N公司 高真空閥門

Gate valves provide straight-through, unimpeded flow with the smallest valve body profile.閘閥提供直通式，暢通，與閥體zui小的個人資料。 Gate valves are ideal for space-constrained applications that require maximum conductance.閘閥是zui大電導(dǎo)為空間受限的應(yīng)用中的理想選擇。 A&N gate valves are available in sizes ranging from 1.5 to 12 inches （nominal ID）. A＆N閘閥尺寸范圍從1.5到12英寸（標(biāo)稱ID）。 Port terminations are available in three flange families （ISO, CF, and ASA）.接口端可在三個的法蘭家庭（ISO，CF，和ASA）。 Manual and pneumatic actuators are available for all A&N gate valves.手動，氣動執(zhí)行器適用于所有A＆N閘閥。 For ultra-high vacuum applications, a copper bonnet seal version （with CF port terminations） is also available.對于超高真空應(yīng)用，銅閥帽密封版本（CF接口端）也是可用的。 Principles of Operation and Construction: A central carriage or gate is raised and lowered by the actuator within the body.*馬車的構(gòu)造和操作原則：A或門提高，降低身體內(nèi)的執(zhí)行機構(gòu)。 In the open position the gate retracts compley from the tube aperture allowing unrestricted flow.在打開位置上的柵極從管孔徑*縮回允許不受限制地流動。 In the closed position an elastomer sealing ring is compressed against the surface on the inside of one of the body ports.在關(guān)閉位置時，被壓縮的彈性體密封環(huán)反對身體端口之一的內(nèi)部的表面上。
