          Introduction

            Angle globe valve is a type of globe valve with an inlet and outlet angle of 90 ° C. In addition to the advantages and usage requirements of general flange globe valves, the biggest feature of this valve is that it is easy to install at the corners of pipeline systems, saving 90 ° C elbows and facilitating opening and closing operations. The flange angle globe valve is widely used in the synthetic ammonia system and refrigeration system of fertilizer plants.
            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,最大的特點(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(kāi)閉操作。法蘭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。

            J44H angle globe valve is only suitable for fully open and fully closed, and is not allowed to be adjusted or throttled. Globe valves belong to forced sealing valves, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters the valve below, the resistance that the operating force needs to overcome is the frictional force between the valve stem and the packing, as well as the thrust generated by the pressure of the medium. The force required to close the valve is greater than that required to open it, so the diameter of the valve stem should be larger, otherwise the failure of the valve stem bending may occur.
            J44H角式截止閥只適用于全開(kāi)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)制密封面不泄漏。當(dāng)介質(zhì)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)閥門的力比開(kāi)閥門的大,所以閥桿的直徑要大,否則會(huì)發(fā)生閥桿頂彎的故障。
