進口先導式電磁閥(德國奧萊斯OLES閥門)
【進口先導式電磁閥】詳細說明:
用于從流動介質(zhì)的能量此類益處閥門致動對于這種類型的開口,并保持開閥壓力差是必需的,對于不同公稱直徑的閥致動,相同的線圈可以被使用,因為分解孔是相同的流動方向被設定為在閥電磁閥是關閉的線圈斷電,定位于先導孔的中心銜鐵保持關閉。在膜頂面時,入口壓力作用(大于輸出壓力),并已通過在膜的裝配孔構成。此壓力作用在膜片上側的表面上,由此產(chǎn)生閉合力大于作用在的開啟力。在無,或在銜鐵管橫膈膜以上的單獨運行由彈簧力這一合閘操作非常低的壓差。所述膜被壓向閥座,閥門保持關閉。
The same coil can be used for valve actuation with different nominal diameters because the same flow direction of the decomposition hole is set to power off the coil closed by the solenoid valve of the valve. The central armature of the pilot hole remains closed. At the top of the membrane, the inlet pressure is greater than the output pressure, and has been formed through the assembly hole of the membrane. This pressure acts on the surface of the upper side of the diaphragm, resulting in a closing force greater than the opening force. In the absence of or above the diaphragm of the armature tube, the switching operation by spring force is very low differential pressure. The membrane is pressed to the seat, and the valve remains closed.
【進口先導式電磁閥】優(yōu)點:
耐腐蝕:零件用不銹鋼或鑄造不銹鋼制成,防腐蝕性能良好
耐高溫:電磁部分、密封件全部采用特種耐高溫電工材料和密封材料,并采用了有效的隔熱措施
耐磨損:選材合理,閥杯和導向套間巧妙地利用流體的潤滑作用,減少磨損
可靠性:結構簡單、緊湊、融合了直動式和先導間接式電磁閥的優(yōu)點,在低壓差或壓差為零情況下也能可靠工作
【進口先導式電磁閥】結構原理:
電磁閥為分步動作直接先導式電磁閥,根據(jù)斷電時開關狀態(tài)的不同,被分為常開型電磁閥和常閉型電磁閥
常開型:通電時,先導孔關閉,閥上腔由活塞節(jié)流孔增壓和復位彈簧的推力,電磁閥關閉。斷電時,先導閥芯靠彈簧復位,先導孔打開,閥上腔卸壓,活塞靠下腔介質(zhì)壓力推動,電磁閥打開
常閉型:通電時,先導閥芯吸合,先導孔打開,閥上腔卸壓,活塞靠下腔介質(zhì)壓力推動,電磁閥打開;斷電時,先導閥芯靠彈簧復位,先導孔關閉,閥上腔由活塞節(jié)流孔增壓和復位彈簧的推力,電磁閥關閉。
