Lever-ball float trap
Lever ball float type trap employs the buoyancy principle and the lever 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 from or touch the valve seat to realize drainage and closed block vapor. The product adopts the automatic air exhaust to automatically eliminate non-condensing air.It is very precise with high operating 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.優點：
1、采用新型閥機構（新 SCCV 關閉方式和Z型結構），具有優良的密封性和耐久性。Merits
1.To use new-style valve mechanism (new SCCV closing mode and Z-shaped structure) to boast excellent tightness and endurance.4.The built-in automatic air exhaust can prevent air blocking and steam locking;
5.As all components are installed on the valve cover,so they can be maintained and cleaned up simply and easily without being removed from pipe arrangement.
