進口高壓角式截止閥德國洛克品牌各種參數(shù)以及說明

進口高壓角式截止閥結(jié)構(gòu)特點：

德國洛克《DE LOCKE》高壓角式截止閥是一種進口和出口呈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)點和使用要求外，*的特點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。

進口高壓角式截止閥工作原理：

簡單來說截止閥的原理就是利用閥桿扭力給密封面一個向下壓力，依靠閥杠壓力，使閥瓣密封面與閥座密封面緊密貼合，阻止介質(zhì)的流入或者用來調(diào)節(jié)介質(zhì)的流速。截止閥的啟閉件是圓柱形的閥瓣，密封面呈平面或錐面，閥瓣沿流體的中心線作直線運動。閥桿的運動方式，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）。截止閥屬于強制密封式閥門，所以在閥門關(guān)閉時，必須向閥瓣施加壓力，以強制密封面不泄漏。

Working principle of imported high pressure angle globe valve:
In short, the principle of the stop valve is to use the stem torque to give a downward pressure to the sealing surface. Depending on the pressure of the valve stem, the sealing surface of the valve disc and the sealing surface of the valve seat are closely connected to prevent the inflow of medium or to adjust the flow rate of medium. The opening and closing part of the stop valve is a cylindrical disc, the sealing surface is flat or conical, and the disc moves linearly along the center line of the fluid. The movement mode of valve stem includes lifting rod type (valve stem lifting, hand wheel not lifting) and lifting rotary rod type (hand wheel and valve stem rotating together, nut is set on the valve body). Stop valve is a forced seal valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak.
                                                                            

進口高壓角式截止閥產(chǎn)品簡介：

德國洛克《DE LOCKE》進口高壓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動。高壓角式截止閥又稱角閥，閥桿的運動形式，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。截止閥屬于強制密封式閥門，所以在閥門關(guān)閉時，必須向閥瓣施加壓力，以強制截止閥的密封面不泄漏。當介質(zhì)由閥瓣下方進入閥門時，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)“高壓角式截止閥” 的力比開“高壓角式截止閥”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。  

Brief introduction of imported high pressure angle globe valve:
The opening and closing parts of the high-pressure Angle Globe Valve imported from German Locke are plug-shaped disc. The sealing surface is flat or conical, and the disc moves in a straight line along the center line of the fluid. High pressure angle stop valve is also known as angle valve. The movement form of stem includes lifting rod type (stem lifting, hand wheel not lifting) and lifting rotary rod type (hand wheel and stem rotating together, nut on the valve body). It is only applicable to full opening and full closing, and no adjustment or throttling is allowed. The globe valve is a forced seal valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface of the globe valve not to leak. When the medium enters the valve from below the disc, the resistance to be overcome by the operating force is the friction between the stem and packing and the thrust generated by the medium pressure. The force to close the "high pressure angle globe valve" is greater than that to open the "high pressure angle globe valve", so the diameter of the stem should be larger, otherwise the stem will be bent.
