杠桿浮球式疏水閥

LEVER-BALL FLOAT TRAP

 

　　杠桿浮球式疏水閥

　　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，浮球驅動著杠桿使得閥瓣離 開或接觸閥座達到開啟排水和關閉阻汽的作用。采用自動排空氣閥，能自動排除不凝結氣體，非常靈敏，工作質量高，使用壽命長。連續(xù)排水，有水即排，zui小過冷 度為 0℃。采用兩種結構方式 A：單閥座-杠桿浮球; B：雙平衡閥座-杠桿浮球。

　　單閥座：需要克服介質壓力對閥座的作用，閥座的孔徑不能很大，適用于小型設備、伴熱管線，蒸汽主管 等排水小的場合。閥座孔設計在凝結水水位以下，自然形成水封，水、汽自然分離，達到無蒸汽泄漏，即便沒有凝結水采用球型密封的杠桿使得閥瓣緊貼閥座，達到 無新鮮蒸汽的泄漏。不受凝結水量波動和溫度的影響。

　　雙平衡閥座：該閥利用雙閥孔設計，介質的壓力對兩個閥座作用相等，方向相反，介質壓力對閥座作用相 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液體位的變化而上下浮動，帶動杠桿打開或關閉閥座。由于閥座孔在凝結水水位以下， 形成水封，水、汽自然分離，達到無蒸汽泄漏。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.

 

 

優(yōu)點：

1、采用新型閥機構（新 SCCV 關閉方式和Z型結構），具有優(yōu)良的密封性和耐久性。

2、雙平衡閥座設計，比一般的疏水閥體積小而排量大，在特大排量場合更能發(fā)揮優(yōu)越性。

3、單閥座設計可以水平或垂直安裝，可以滿足高背壓，低排量蒸汽管線。

4、內裝空氣自動排放閥，可防止空氣氣堵和蒸汽汽鎖。

5、全部部件安裝在閥蓋上，閥無需從配管上卸下，就可維修保養(yǎng)，簡單方便。

 

Merits

1. To use new-style valve mechanism （new SCCV closing mode ａnd Z-shaped structure） to boast excellent tightness ａnd endurance.

2. To employ double balanced valve seat design, it has smaller volume ａnd larger displacement ａnd can exert its advantages when needing large displacement.

3. The single valve seat model can be installed horizontally ａnd vertically, satisfying the requirements of steam pipeline with high backpressure ａnd low displacement.

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.
