熱靜力型疏水閥

THERMO-STATIC （BELLOWS SEAL） TRAP

　　波紋管式疏水閥的熱敏元件為注滿易揮發(fā)液體的波紋管，利用液體的易揮發(fā)性和波紋管伸縮性。當(dāng)蒸汽管線升溫時(shí)，液體揮發(fā)成氣體體積膨脹并產(chǎn)生壓力推動(dòng)著波紋管伸長，蒸汽管線降溫達(dá)到易揮發(fā)的液體從氣體轉(zhuǎn)變成液體時(shí)體積縮收，波紋管內(nèi)沒有推動(dòng)力，波紋管縮收。

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.

熱靜力型疏水閥優(yōu)點(diǎn)：

1、排水溫度可以調(diào)節(jié)在70~100度之間，使用方便。

2、能夠阻止高溫凝結(jié)水的排放，保持蒸汽管線的熱能。

3、連續(xù)排水，沒有噪音。

4、蒸汽壓力小波動(dòng)不影響使用。

5、結(jié)構(gòu)簡單，體積小，安裝方便、隨意。

6、通過增加波紋管直徑提高凝結(jié)水的排量。

7、具有良好的排空氣性能，不怕凍。

8、零泄漏，背壓率達(dá)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%.

安裝、使用注意事項(xiàng)：

　　安裝前管路應(yīng)用蒸汽吹除污物。箭頭所示方向與流向一致。

　　疏水閥前熱力管應(yīng)有1～2米不必保溫。應(yīng)安裝在低于用汽設(shè)備凝結(jié)水排出點(diǎn)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.
