〖德國萊克杠桿浮球式疏水閥〗
德國LIK杠桿浮球式是利用浮力原理和杠桿原理，通過液位的變化使浮球上升或下降，浮球驅(qū)動著杠桿使得閥瓣離開或接觸閥座達(dá)到開啟排水和關(guān)閉阻汽的作用。采用自動排空氣閥，能自動排除不凝結(jié)氣體，非常靈敏，工作質(zhì)量高，使用壽命長。連續(xù)排水，有水即排，zui小過冷度為 0℃。杠桿浮球式疏水閥采用兩種結(jié)構(gòu)方式 A：單閥座-杠桿浮球; B：雙平衡閥座-杠桿浮球。
單閥座：需要克服介質(zhì)壓力對閥座的作用，閥座的孔徑不能很大，適用于小型設(shè)備、伴熱管線，蒸汽主管等排水小的場合。閥座孔設(shè)計(jì)在凝結(jié)水水位以下，自然形成水封，水、汽自然分離，達(dá)到無蒸汽泄漏，即便沒有凝結(jié)水采用球型密封的杠桿使得閥瓣緊貼閥座，達(dá)到無新鮮蒸汽的泄漏。不受凝結(jié)水量波動和溫度的影響。
雙平衡閥座：該閥利用雙閥孔設(shè)計(jì)，介質(zhì)的壓力對兩個閥座作用相等，方向相反，介質(zhì)壓力對閥座作用相抵消，閥芯在開閥時壓力相對減少，從而獲得超大排量。工作時浮球隨閥腔內(nèi)液體位的變化而上下浮動，帶動杠桿打開或關(guān)閉閥座。由于閥座孔在凝結(jié)水水位以下，形成水封，水、汽自然分離，達(dá)到無蒸汽泄漏。不受壓力、溫度、冷凝水流量波動的影響。
Lever-ball float trap
The lever-ball float type trap employs the buoyancy and leverage principles: to make the ball float ascend or descend by the change in the liquid level and then the ball float drives the lever to make the valve disc depart from or touch the valve seat to realize drainage and close the block vapor. The product adopts the automatic air exhaust to automatically eliminate non-condensing air. It is very precise with high operating quality and long service life. It can discharge whenever there is any water, and its minimum subcooled temperature is 0℃. The lever- ball float trap adopts two kinds of structure modes: A: Single valve seat-lever ball float; B: double balanced valve seat-lever ball float.
Single valve seat: it needs to overcome the operation on the valve seat by the medium pressure; the hole caliber of the valve seat cannot be too large and is applicable to such low displacement condition as mini-equipment, steam tracing pipeline and steam main pipe. The hole of the valve seat is designed beneath the water level of the condensate water to form water sealing to keep water apart from vapor, so as to prevent the leakage of the vapor. Though there is no condensate water that uses ball-type sealed lever to make the valve clack tightly adhesion to the valve seat, it can prevent the fresh vapor from leakage. Further, the product is free of the affect of the fluctuation of the condensate water’s quantity and temperature.
The double balanced valve seat: this valve is designed to have two valve openings. The pressure of the medium act against the two valve seats equally in reverse direction, so the pressure on the valve seat is offset, the valve core assumes relatively low pressure when the valve is open, in this way the overlarge displacement is obtained. During the operating process, the ball float floats with the change in liquid level of the valve cavity to make the lever open or close the valve seat. The hole of the valve seat is designed beneath the water level of the condensate water to form water sealing to keep water apart from vapor, so as to prevent the leakage of the vapor. Further, the product is free of the affect caused by the fluctuation of pressure, temperature and condensate’s flow.
