在各種疏水閥的工作原理中,倒置桶型是最的,其全部設(shè)計的核心是一個獨(dú)特的杠桿系統(tǒng),該系統(tǒng)將浮桶的重力放大以便開啟受到壓差作用的閥瓣。
由于浮桶開口倒置,所以它可以防止由于水擊所造成的損壞,并且為了延其使用壽命,各磨損點(diǎn)都采取了加固措施。倒置桶型疏水閥只有兩個運(yùn)動部件――閥門杠桿懸掛件及倒置桶,不存在固定支點(diǎn)和復(fù)雜的連接,不會發(fā)生卡死和阻塞。
即使零件磨損后仍可節(jié)能阿姆斯壯倒置桶型疏水閥的開啟與關(guān)閉是根據(jù)凝結(jié)水和蒸汽的密度差來工作的――倒置桶原理。其開啟動作非常輕緩,從而減少了磨損,這一簡單的事實表明倒置桶型疏水閥的磨損大大小于其它種類的疏水閥。
事實上,阿姆斯壯倒置桶型疏水閥發(fā)生磨損后其密封反而有所改善,因為閥瓣和閥座形成了完整的接觸環(huán)線,所有的關(guān)閉力都集中在較窄的密封環(huán)線上,從而加強(qiáng)了密封。
隨著使用時間的增加,阿姆斯壯倒置桶型疏水閥將繼續(xù)的工作,實際磨損使閥孔的直徑略微增加,而它愈磨損,其密封性就愈好,因為隨著磨擦的增大,球型閥瓣就越來越深的陷入閥座中,從而了密封性。
耐磨耐腐蝕部件阿姆斯壯倒置桶型疏水閥的不銹鋼閥瓣和閥座被單獨(dú)磨削加工后在機(jī)械裝置上一起配研,所有的其它部件都采用耐磨損、耐腐蝕的不銹鋼。
空氣和二氧化碳的排放阿姆斯壯倒置桶型蒸汽疏水閥可以自動連續(xù)地排放空氣和二氧化碳?xì)怏w而沒有冷滯后或空氣阻。
在背壓下工作阿姆斯壯倒置桶型疏水閥對背壓具有很好的適應(yīng)性,除了由于壓差變小減少流量外,沒有其它不利影響,倒置桶只需要較小的力就可使疏水閥開啟。
無污物困擾阿姆斯壯倒置桶型疏水閥的獨(dú)特設(shè)計使之在工作時幾乎不受污物困擾,閥瓣與閥座都設(shè)置在疏水閥的頂部,遠(yuǎn)離沉積在底部的大顆粒污物,倒置桶的上下動作使其變成了粉沫。
由于倒置桶所控制的閥孔不是全開,就是全關(guān),污物顆?梢宰杂赏ㄟ^,從倒置桶下邊快速流過的凝結(jié)水形成一種獨(dú)特的自清洗水流,將污物帶出疏水閥。查看特定型號的倒置桶疏水閥,請參考下面的描述,或到上面的菜單欄進(jìn)行選擇。

santotrac traction lubricants
fluid lubricants that solidify during use can enhance the power output of traction drives while extending their useful lives. these lubricants extend the life of industrial gearless planetroll type systems and are the choice lubricants for the new generation automotive transmission systems where continuously variable transmission (cvt) are used.
santotrac products
traction lubricants are synthetic hydrocarbon fluids that become solid under high stress and high shear. they are liquid beyond the contact area, which makes them useful in traction type drives. these products have high coefficient of traction (ratio of transmitted force to contact force) and molecular stability to resists high shear, high speeds, and pressures, while maintaining the integrity of the film between the stressed metal surfaces. santotrac lubricants undergo unusually high transitory viscosity-increase under high pressures. it has been demonstrated that contact pressures of 700,000 psi have not succeeded in destroying the integrity of the film between metal-to-metal rolling surfaces. santotrac lubricants are produced in a range of viscosity grades, wide enough to enable the user to se-lect the most suitable viscosity for a particular operating condition and application. all grades offer stability at high temperature, high coefficient of traction and good lubricating performance.
some of the specific products produced and sold today are as follows:
traction lubricants / fluids |
santotrac 32, low viscosity, high traction fluid |
santotrac 50, low viscosity, high traction fluid |
santotrac 70, high viscosity, high traction lubricant |
santotrac 100, high viscosity, high traction lubricant |
santotrac 2000, low temperature, high traction lubricant |
santotrac 3000, automotive cvt fluid |
hydratorque 1842b, low viscosity, medium traction fluid |
mcs-2080 a, aviation traction fluid |
