德國凱士比KSB DN50蝶閥

Germany KSB KSB DN50 butterfly, with excellent anti-friction, self-lubricating, operating torque lower than normal, a pin butterfly forty percent; for temperature ≤120 ℃ or ≤150 ℃, nominal pressure ≤1.6MPa drainage , sewage, food, heating, gas, shipping, hydropower, metallurgy, energy systems, and textile and other industries, especially for two-way valve seal and easily corroded occasions, regulating traffic and closure of media.
德國凱士比KSB DN50蝶閥，具有優(yōu)異的減磨、自潤滑性，操作力矩比普通有銷蝶閥降低百分之四十；適用于溫度≤120℃或≤150℃，公稱壓力≤1.6MPa給排水、污水、食品、供暖、燃?xì)狻⒋啊⑺姟⒁苯稹⒛茉聪到y(tǒng)以及輕紡等行業(yè)，特別適用于雙向密封和閥體易銹蝕場合，作調(diào)節(jié)流量和截流介質(zhì)。
Structural features:
· Integration penetrating shaft: ensure precise valve POSTTTIoning strength, reliability combined valve plate.
· O-ring: helps prevent shaft leakage.
· Precision Taper Pin: vibration proof, shaft to disc plate. Can be replaced in the field.
· Precise and accurate contour disc: to prevent the "bubble tight" shut difficult to ensure maximum effective torque, extending seat life.
· Supported Shaft Seal: elastic material with a phenolic backing ring of close combination, effectively preventing the leakage of distortion caused by the shaft.
· Both for gaseous medium, it is also applicable to a liquid medium.
It can be two-way Close
· Alternative repair pipeline terminal
結(jié)構(gòu)特性：
· 一體化貫穿軸：確保閥門的強(qiáng)度、可靠性合閥板的精確定位。
·O形圈：有助于防止軸泄漏。
·精密準(zhǔn)確的錐形銷釘：增強(qiáng)防震保護(hù)，強(qiáng)化軸與蝶板的結(jié)合。可在現(xiàn)場更換。
·精密準(zhǔn)確的蝶板輪廓：防止“泡緊”關(guān)閉困難，確保最大程度見效扭矩，延長閥座壽命。
·支撐性軸密封：彈性材料與酚醛背襯環(huán)的緊密結(jié)合體，有效防止由于扭曲變形導(dǎo)致的軸泄漏。
·既適用于氣態(tài)介質(zhì)，也適用于液態(tài)介質(zhì)。
·可進(jìn)行雙向關(guān)閉
·備選維修管道終端
設(shè)計(jì)規(guī)范：
