热静力型疏水阀

THERMO-STATIC （BELLOWS SEAL） TRAP

　　波纹管式疏水阀的热敏元件为注满易挥发液体的波纹管，利用液体的易挥发性和波纹管伸缩性。当蒸汽管线升温时，液体挥发成气体体积膨胀并产生压力推动着波纹管伸长，蒸汽管线降温达到易挥发的液体从气体转变成液体时体积缩收，波纹管内没有推动力，波纹管缩收。

Bellows seal trap

The thermo-sensitive element of bellows seal traps is bellows filled with volatile liquid, which employs the volatility of the liquid ａnd flexibility of the bellows. When temperature of the steam pipe goes up, the liquid volatilizes into gas, the size expands ａnd produces pressure to impel bellows to stretch. In contrast, when temperature of the steam pipe goes down to the temperature for gas to turn into liquid, the size gets smaller ａnd the bellows contract due to lack of impetus.

 

热静力型疏水阀优点：

1、排水温度可以调节在70~100度之间，使用方便。

2、能够阻止高温凝结水的排放，保持蒸汽管线的热能。

3、连续排水，没有噪音。

4、蒸汽压力小波动不影响使用。

5、结构简单，体积小，安装方便、随意。

6、通过增加波纹管直径提高凝结水的排量。

7、具有良好的排空气性能，不怕冻。

8、零泄漏，背压率达到75%。

 

Merits

1.Convenient use due to adjustable water discharge temperature ranging from 70 to 100 degrees.

2.Capability to prevent discharge of high-temperature condensate so as to maintain heat energy of the steam pipe.

3.Continuous water discharge without noise.

4.Free from the effect of small fluctuation of steam pressure.

5.Simple structure, small size ａnd easy installation.

6.Improvement of discharge capacity of condensate by increasing diameter of bellows.

7.Good air discharge performance with resistance to coldness.

8.Zero leakage ａnd backpressure ratio up to 75%.

 

安装、使用注意事项：

　　安装前管路应用蒸汽吹除污物。箭头所示方向与流向一致。

　　疏水阀前热力管应有1～2米不必保温。应安装在低于用汽设备凝结水排出点的地方。

 

 

Installation/attention for use

Before the installment of pipeline, use the steam to blow off the pollutant. The arrow shows the direction consistent with the flow direction.

Ahead of the trap, the thermal tube of 1~2 meters need no heat-preservation. Be installed at the position lower than the condensation water discharge point of the steam-using equipment.

Before leaving the plant, the hydrophobic temperature of trap has been adjust around 95℃. If it is needed to change the hydrophobic temperature or the displacement, open the shielding bonnet, loosen the lock nut, revolve the adjusting screw revolve the valve core clockwise, the hydrophobic volume reduces ａnd the hydrophobic temperature drops; revolve it counterclockwise, the valve core backlashes, the hydrophobic volume increases, ａnd the hydrophobic temperature rises. After the adjustment ended, tighten the lock nut.

It is needed to make the periodic maintenance ａnd clear the pollutant before the filtration screen, so as to guarantee the trap work normally.
