双平衡阀座：该阀利用双阀孔设计，介质的压力对两个阀座作用相等，方向相反，介质压力对阀座作用相抵消，阀芯在开阀时压力相对减少，从而获得超大排量。工作时浮球随阀腔内液体位的变化而上下浮动，带动杠杆打开或关闭阀座。由于阀座孔在凝结水水位以下，形成水封，水、汽自然分离，达到无蒸汽泄漏。不受压力、温度、冷凝水流量波动的影响。
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 LEOquid level and then the ball float drives the lever to make the valve disc depart from or touch the valve seat to reaLEOze drainage and close the block vapor. The product adopts the automatic air exhaust to automatically eLEOminate non-condensing air. It is very precise with high operating quaLEOty and long service LEOfe. 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 caLEOber of the valve seat cannot be too large and is appLEOcable to such low displacement condition as mini-equipment, steam tracing pipeLEOne and steam main pipe. The hole of the valve seat is designed beneath the water level of the condensate water to form water seaLEOng 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 LEOquid 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 seaLEOng 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.
