進(jìn)口螺紋電磁閥概述:
德國(guó)泰科螺紋電磁閥是一種具有隔爆外殼的電氣設(shè)備。隔爆外殼能承受已進(jìn)入外殼內(nèi)部的可燃性混合物內(nèi)部爆炸而不損壞,并且通過(guò)外殼上的任何接合面或結(jié)構(gòu)孔不會(huì)引燃一種或多種氣體或蒸氣所形成的外部爆炸性環(huán)境的電氣設(shè)備。
進(jìn)口電磁閥可選參數(shù)范圍:
◇產(chǎn)品規(guī)格━DN0.5~DN1000
◇閥體材質(zhì)━鑄鐵、不銹鋼 (鑄鐵不能用在腐蝕流體上)
◇溫度范圍-200~+350℃◇適用介質(zhì)━易燃易爆液體或氣體
◇防護(hù)性能━防水、防爆(Exd IICT5)、防腐
◇控制方式━常開(kāi)、常閉
◇電源電壓━DC12~DC127V; AC36~380V
◇連接方式━內(nèi)螺紋、法蘭 (其他特殊接口可定做或加轉(zhuǎn)接頭)
◇泄漏量━零
◇備注━特殊大口徑閥可定制,大口徑可做到DN500(mm)
◇防爆電磁閥工作原理:
常閉━當(dāng)線圈通電時(shí),先導(dǎo)閥芯吸合,先導(dǎo)孔打開(kāi),閥上腔卸壓,活塞靠下腔介質(zhì)壓力推動(dòng),電磁閥打開(kāi)。當(dāng)線圈斷電時(shí),先導(dǎo)閥芯靠彈簧復(fù)位,先導(dǎo)孔關(guān)閉,閥上腔由活塞節(jié)流孔增壓和復(fù)位彈簧的推力,電磁閥關(guān)閉。

Overview of the solenoid valve inlet thread:
Is a kind of flameproof enclosures for electrical equipment. Flameproof enclosure into the interior of the housing to withstand the internal explosion of flammable mixture without damage, and through any joints or on the housing structure of one or more holes will not ignite the gas or vapor form an explosive environment external electrical device.
Solenoid valve optional parameter range:
◇ ━Specifications ━ DN0.5 ~ DN1000
◇ ━ body material cast iron, stainless steel (cast iron can not be used in corrosive fluid on)
◇ ━temperature range -200 ~ +350 ℃
◇ ━Applicable medium flammable explosion protection performance liquid or gas
◇ ━ waterproof, explosion-proof (Exd IICT5), corrosion control
◇ ━normally open, normally closed
◇ ━Power supply DC12 ~ DC127V; AC36 ~ 380V
◇ ━ connection internal thread, flange (other special interface or add custom adapter)
◇━Remarks zero leakage special large diameter valves can be customized, maximum diameter can be achieved DN500 (mm)
◇━proof solenoid valve works: NC when the coil is energized, the pilot spool suck together, the pilot hole opened, pressure relief valve chamber, the piston on the lower chamber medium pressure to promote, the solenoid valve opens. When the coil is de-energized, the pilot valve by spring return, pilot hole is closed, the valve orifice chamber pressurized by the piston return spring and thrust, the solenoid valve closes. ━ normally open when the coil is energized, the pilot valve by spring return, pilot hole is closed, the valve chamber and pressurized by the piston return spring throttle thrust, the solenoid valve closes. When the coil is de-energized, the pilot valve by spring return, pilot hole opened, pressure relief valve chamber, the piston on the lower chamber medium pressure to promote, the solenoid valve opens. Note: The outlet pressure is greater than the inlet pressure, the media will reverse conduction. Check valve can be installed.
