進(jìn)口角式截止閥
德國巴赫進(jìn)口角式截止閥概述：
進(jìn)口角式截止閥的啟閉件是塞形的閥瓣，密封面呈平面或錐面，閥瓣沿流體的中心線作直線運(yùn)動。角式截止閥又稱角閥，閥桿的運(yùn)動形式，有升降桿式（閥桿升降，手輪不升降），也有升降旋轉(zhuǎn)桿式（手輪與閥桿一起旋轉(zhuǎn)升降，螺母設(shè)在閥體上）。只適用于全開和全關(guān)，不允許作調(diào)節(jié)和節(jié)流。截止閥屬于強(qiáng)制密封式閥門，所以在閥門關(guān)閉時(shí)，必須向閥瓣施加壓力，以強(qiáng)制截止閥的密封面不泄漏。當(dāng)介質(zhì)由閥瓣下方進(jìn)入閥門時(shí)，操作力所需克服的阻力，是閥桿和填料的摩擦力與由介質(zhì)的壓力所產(chǎn)生的推力，關(guān)“角式截止閥” 的力比開“角式截止閥”的力大，所以閥桿的直徑要大，否則會發(fā)生閥桿頂彎的故障。
Inlet angle stop valve
Overview of Bach inlet angle valve:
Inlet angle type valve opening and closing parts are plug shaped valve, sealing surface flat or cone, fluid along the centerline of the valve for linear motion. Angle type globe valve, also known as angle valve, the movement of the stem form, there are lifting rod (stem lift, hand wheel is not up and down), but also the lifting of the rotary rod (hand wheel and stem together with the rotation of the nut in the valve body). Only applicable to fully open and fully closed, does not allow for adjustment and throttle. Valve is a mandatory seal valve, so the valve is closed, the valve must be applied to force the valve sealing surface does not leak. When the medium into the valve from the bottom of the valve, the operating force required to overcome the resistance, is the stem and the packing friction and pressure generated by the media thrust, "angle type valve" than "open angle type stop valve force, so the diameter of the valve stem, otherwise it will bend the stem top of the fault.
進(jìn)口角式截止閥的定義：
進(jìn)口角式截止閥是一種進(jìn)口和出口呈90°C夾角的截止閥，這種閥門除了具備一般法蘭截止閥的優(yōu)點(diǎn)和使用要求外，zui大的特點(diǎn)就是方便安裝在管道系統(tǒng)的拐角處，既節(jié)省了90°C的彎頭，又方便開閉操作。高壓角式截止閥在化肥廠的合成氨系統(tǒng)和制冷系統(tǒng)中等到非常廣泛的應(yīng)用。
Define the entry angle type valve:
Inlet angle type valve is a valve in the import and export of 90 DEG C angle, in addition to this valve has the advantages of general flange valve and operation requirements, the biggest feature is easy to install in the corner of the pipeline system, not only saves the elbow 90 degrees C, and convenient opening and closing operation. High angle stop valve in the chemical fertilizer plant ammonia system and refrigeration system until a very wide range of applications.
