進(jìn)口蒸汽截止閥

蒸汽截止閥（stop valve,Globe Valve）的啟閉件是塞形的閥瓣，密封上面呈平面或海錐面，閥瓣沿閥座的中心線作直線運(yùn)動(dòng)。閥桿的運(yùn)動(dòng)形式，（通用名稱：暗桿），也有升降旋轉(zhuǎn)桿式可用于控制空氣、水、蒸汽、各種腐蝕性介質(zhì)、泥漿、油品、液態(tài)金屬和放射性介質(zhì)等各種類型流體的流動(dòng)。因此，這種類型的截流截止閥閥門非常適合作為切斷或調(diào)節(jié)以及節(jié)流用。由于該類閥門的閥桿開啟或關(guān)閉行程相對(duì)較短，而且具有非常可靠的切斷功能，又由于閥座通口的變化與閥瓣的行程成正比例關(guān)系，非常適合于對(duì)流量的調(diào)節(jié)。此閥是德國(guó)先進(jìn)機(jī)械技術(shù)，采用雙層波紋管設(shè)計(jì)，焊于閥桿保持穩(wěn)定的運(yùn)行性能，避免由于閥塞振動(dòng)引起閥桿振動(dòng)。在高溫情況下，閥桿不與介質(zhì)接觸，確保閥桿零泄漏。同時(shí)保證足夠的強(qiáng)度和韌性，可以開關(guān)上萬次。手輪采用人體工程學(xué)設(shè)計(jì)，使用壽命更長(zhǎng)，操作輕松便捷。蒸汽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(dòng)，也叫截門，是使用最廣泛的一種閥門，它之所以廣受歡迎，是由于開閉過程中密封面之間摩擦力小，比較耐用，開啟高度不大，制造容易，維修方便，不僅適用于中低壓，而且適用于高壓。廣泛適用于食品、醫(yī)藥、石油、化工、天然氣、鋼鐵、環(huán)保、造紙等輸送管路中做介質(zhì)切斷或流通。

進(jìn)口蒸汽截止閥 - 優(yōu)點(diǎn)

(1)蒸汽截止閥結(jié)構(gòu)比閘閥簡(jiǎn)單，制造與維修都較方便。

(2)密封面不易磨損及擦傷，密封性好，啟閉時(shí)閥瓣與閥體密封面之間無相對(duì)滑動(dòng)，因而磨損與擦傷均不嚴(yán)重，密封性能好，使用壽命長(zhǎng)。

(3)啟閉時(shí)，閥瓣行程小，因而截止閥高度比閘閥小，但結(jié)構(gòu)長(zhǎng)度比閘閥長(zhǎng)。

(4)啟閉力矩大、啟閉較費(fèi)力，啟閉時(shí)間校長(zhǎng)。

(5)流體阻力大，因閥體內(nèi)介質(zhì)通道較曲折，流體阻力大，動(dòng)力消耗大。

(6)介質(zhì)流動(dòng)方向公稱壓力PN≤16MPa時(shí)，一般采用順流，介質(zhì)從閥瓣下方向上流；公稱壓力PN≥20MPa時(shí)，一般采用逆流，介質(zhì)從閥瓣上方向下流．以增加密封件能。使用時(shí)，截止閥介質(zhì)只能單方向流動(dòng)，不能改變流動(dòng)方向。

(7)全開時(shí)閥瓣經(jīng)常受沖蝕。蒸汽截止閥的閥桿軸線與閥座密封面垂直。閥桿開啟或關(guān)閉行程相對(duì)較短，并具有非常可靠的切斷動(dòng)作，使得這種閥門適合作為介質(zhì)的切斷或調(diào)節(jié)及節(jié)流使用。

Imported steam stop valve

Steam stop valve (stop valve, Globe Valve) opening and closing parts are plug-shaped valve, seal or sea centerline plane was above the cone, the valve seat along a straight line. Stem form of exercise, (generic name: dark bar), but also lift rotating rod can be used to control air, water, steam, corrosive media, mud, oil, liquid metals and radioactive fluids and other types of media flow. Therefore, this type of shut-off valve shut-off valve is very suitable as cut or regulation and throttle use. As such the valve stem to open or close the relatively short trip, but also has a very reliable cutting function, but also due to travel proportional to changes in the valve seat and the valve port valve is very suitable for flow regulation. This valve is Germany advanced mechanical technology, using double bellows design, welded to the valve stem to maintain a stable operating performance, avoid the vibration caused by the valve plug stem vibration. At high temperatures, the stem is not in contact with the media to ensure zero leakage valve stem. While ensuring sufficient strength and toughness, can be thousands of times the switch. Ergonomically designed hand wheel, longer life, easy and convenient operation. Steam stop valve opening and closing parts of the plug-shaped valve, leaving it flat or cone seal, fluid along the centerline of the valve in a straight line, also known as the cross-sectional doors, is the most widely used as a valve that reason popularity is due to the process of opening and closing between the sealing surface friction is small, more durable, opening height is not easy to manufacture, easy maintenance, not only for low pressure, and is suitable for high pressure. Widely used in food, medicine, petroleum, chemical, natural gas, steel, environmental protection, paper and other media to do the transfer line cut or circulation.

Imported steam stop valve - Benefits

(1) steam stop valve structure simpler than the gate, manufacturing and maintenance are more convenient.

(2) sealing surface easy to wear and abrasion, sealing, and no relative sliding between the valve and valve sealing surface when opening and closing, and thus wear and scratches are not serious, good sealing performance and long service life.

(3) When opening and closing, the valve stroke is small, and therefore smaller than the height of the valve shut-off valves, but the structure is longer than the length of the gate.

(4) opening and closing torque, relatively effortless opening and closing, opening and closing time of the principal.

(5) fluid resistance, due to the valve body media path more tortuous, large fluid resistance, power consumption.

(6) Nominal medium flow direction PN≤16MPa, generally used downstream, upstream from the media under the direction of the valve; when nominal PN≥20MPa, generally countercurrent, media orientation downstream from the valve. To increase the seal performance. When used, the cut-off valve medium can only flow in one direction, you can not change the direction of flow.

(7) when fully open valve is often affected by erosion. Stem and seat sealing surface perpendicular to the axis of the steam shut-off valve. Stem to open or close the relatively short trip, and have very reliable cutting action, making this valve is suitable for medium cut or regulation and throttle use.
