進(jìn)口法蘭閘閥(德國(guó)OLES奧萊斯閥門)
【進(jìn)口法蘭閘閥】詳細(xì)說(shuō)明:
閘閥是一種常見(jiàn)的啟閉閥,利用閘板(即啟閉件,在閘板中啟閉件稱為閘板或閘門,閘座稱為閘板座)來(lái)接通(全開(kāi))或截?cái)啵ㄈP(guān))管路中的介質(zhì)。它不允許作為截流用,使用中應(yīng)避免將閘板微量開(kāi)啟,因高速流動(dòng)的介質(zhì)的沖蝕會(huì)加速密封面的損壞。閘板在垂直于閘門座通道中心線的片面作為升降運(yùn)動(dòng),象閘門一樣截?cái)喙苈分械慕橘|(zhì),故稱做閘閥??蓮V泛用于自來(lái)水、污水、建筑、石油、化工、食品、醫(yī)藥、輕紡、電力、船舶、冶金、能源系統(tǒng)等體管線上作為調(diào)節(jié)和截流裝置使用
Gate valve is one of the most common open and close valves. The medium in the pipeline can be connected (fully opened) or cut off (fully closed) by using gate (that is, opening and closing parts, which are called gate or gate in the gate, and gate seat). It is not allowed to be used as interception. It should be avoided to open the gate slightly in use, because the erosion of high-speed flowing media will accelerate the damage of the sealing surface. The gate is called a gate valve because it acts as lifting motion on one side perpendicular to the center line of the gate pedestal passage and cuts off the medium in the pipeline like a gate. It can be widely used in water, sewage, construction, petroleum, chemical industry, food, medicine, textile, power, ship, metallurgy, energy system and other body pipelines as regulating and closing devices.
【進(jìn)口法蘭閘閥】特性:
1、流動(dòng)阻力小。閥體內(nèi)部介質(zhì)通道是直通的,介質(zhì)成直線流動(dòng),流動(dòng)阻力小。
2、啟閉時(shí)較省力。是與截止閥相比而言,因?yàn)闊o(wú)論是開(kāi)或閉,閘板運(yùn)動(dòng)方向均與介質(zhì)流動(dòng)方 向相垂直。
3、高度大,啟閉時(shí)間長(zhǎng)。閘板的啟閉行程較大,降是通過(guò)螺桿進(jìn)行的。
4、水錘現(xiàn)象不易產(chǎn)生。原因是關(guān)閉時(shí)間長(zhǎng)。
5、介質(zhì)可向兩側(cè)任意方向流動(dòng),易于安裝。閘閥通道兩側(cè)是對(duì)稱的。
6、結(jié)構(gòu)長(zhǎng)度(系殼體兩連接端面之間的距離)較小。
7、形體簡(jiǎn)單 , 結(jié)構(gòu)長(zhǎng)度短,制造工藝性好,適用范圍廣。
8、結(jié)構(gòu)緊湊,閥門剛性好,通道流暢,流阻數(shù)小,密封面采用不銹鋼和硬質(zhì)合金,使用壽命長(zhǎng),采用PTFE填料.密封可靠.操作輕便靈活。
【進(jìn)口法蘭閘閥】特點(diǎn):
采用楔式彈性閘板結(jié)構(gòu),中﹑大口徑設(shè)置滾動(dòng)軸承,啟閉輕松。中法蘭采用不銹鋼纏繞墊片,閥桿密封采用柔性石墨填料,密封可靠。結(jié)構(gòu)設(shè)計(jì)緊湊合理,造型美觀。
