倒吊桶式蒸汽疏水閥它是利用冷凝水和蒸汽的密度差的工作原理，內(nèi)部結(jié)構(gòu)是由杠桿系統(tǒng)連接倒吊桶，克服蒸汽壓力開關(guān)倒吊桶式疏水閥內(nèi)部是一個倒吊桶為液位敏感件，倒吊桶開口向下

詳細(xì)介紹

倒吊桶式蒸汽疏水閥它是利用冷凝水和蒸汽的密度差的工作原理，內(nèi)部結(jié)構(gòu)是由杠桿系統(tǒng)連接倒吊桶，克服蒸汽壓力開關(guān)倒吊桶式疏水閥內(nèi)部是一個倒吊桶為液位敏感件，倒吊桶開口向下。裝置剛起動時，管道內(nèi)出現(xiàn)空氣和低溫冷凝水，此時疏水閥是全開放，空氣和低溫冷凝水迅速排出，裝置很快提升溫度。當(dāng)蒸汽進(jìn)入倒吊桶內(nèi)，倒吊桶產(chǎn)生向上浮力，倒吊桶連接杠桿帶動閥心關(guān)閉閥門。倒吊桶上開有一小孔，能自動排空氣，當(dāng)一部份蒸汽從小孔排出，另一部份蒸汽產(chǎn)生凝結(jié)水，倒吊桶失去浮力向下沉，倒吊桶連接杠桿帶動閥心開啟閥門。當(dāng)蒸汽再進(jìn)入倒吊桶內(nèi)，閥門再關(guān)閉，循
環(huán)工作，間斷排水
倒吊桶式蒸汽疏水閥是機(jī)械型蒸汽疏水閥中堅固的疏水閥之一，它的優(yōu)點(diǎn)是：不怕水擊，能連續(xù)排不冷凝氣體，抗污性能好；背壓≥90%，所有內(nèi)件都是不銹鋼制造，耐磨損、抗腐蝕；球形閥心和閥座是線接觸，密封性能好，使用壽命長；間斷排水和連續(xù)排水，能排接近飽和溫度冷凝水，使加熱設(shè)備達(dá)到理想工作效率。倒吊桶式蒸汽疏水閥的閥座處于水密封的保護(hù)下，工作時無活蒸汽泄漏，節(jié)能效果好。
它適用于石油、化工、印刷、造紙、制藥等工業(yè)蒸汽加熱設(shè)備和蒸汽管網(wǎng)的阻汽排水。

Inverted Bucket Trap
The interior of the inverted bucket steam trap:this valve adopts the operating principles of density difference between condensate water and steam,ａnd the leverage system connects with inverted bucket to form its internal structure,thus controlling the open and close of the steam pressure.The interior of the inverted bucket steam trap is an inverted bucket,a liquid level sensitive part,with the bucket's opening downward.When the device just started,air and low temperature condensate water occur in the pipes,at the moment the steam trap opens thoroughly,the air and low-temperature condensate water are discharged rapidly and the temperature of the device rises immediately.When any steam enters into the inverted bucket,the bucket will obtain buoyancy and the fixed lever of the bucket drives the valve core to close the valve.There is small aperture on the inverted bucket,which can discharge air automatically.As some of steam is discharged from such aperture,while other steam produces condensate water.The inverted bucket loses the buoyancy and sinks down and its fixed lever drives the valve core to open the valve.When the steam re-enters into the bucket,the valve will close again.It repeats the said procedures to discharge water intermittently.
The inverted bucket steam trap is one of the most solid mechanical steam traps. It has the following advantages: it is not afraid of water hammer, can continuously discharge non condensing gas, and has good anti pollution performance; the maximum back pressure is ≥ 90%, all internal parts are made of stainless steel, wear-resistant and anti-corrosion; the ball valve core and valve seat are in line contact, with good sealing performance and long service life; intermittent drainage and continuous drainage It can discharge condensate close to saturation temperature and make heating equipment reach ideal working efficiency. The valve seat of inverted bucket steam trap is under the protection of water seal, and there is no live steam leakage during operation, so the effect of energy saving is good.
The product applies to such industrial steam heating equipment as petroleum,chemical,printing,paper making and pharmaceuticals and discharge of the steam pipe network.

優(yōu)點(diǎn)：

1、對凝結(jié)水的發(fā)生量適應(yīng)性強(qiáng)，既可間歇排放，又可連續(xù)排放。

2、內(nèi)部裝有大排量的雙閥座差壓機(jī)和SCCV關(guān)閉系統(tǒng)，體積小而排量大。

3、內(nèi)部零件全部采用不銹鋼制造，并且安裝在閥蓋上維修保養(yǎng)極為方便。

4、背壓率高（90%）。

5、汽水分離可靠（水汽經(jīng)U型通道從閥下部進(jìn)入），閥內(nèi)始終處于水封狀態(tài)，有效阻止蒸汽泄露。
6、敞口型的浮子抗水擊，吊桶上設(shè)有排水孔，可有效防止蒸汽氣鎖、空氣氣堵現(xiàn)象（非凝結(jié)性的高溫空氣也排除）。

7、與杠桿機(jī)構(gòu)結(jié)合制造高壓閥。

Merits

1.Strong adaptability to happening of condensate water,capable of intermittent or continuous discharge.

2.Equipped with double-valve pressure differentiator and SCCV shutdown system,with small size but large discharge capacity.

3.All inner parts made of stainless steel and mounted on valve covers,easy to maintain and repair.

4.High backpressure rate of 90%.

5.Reliable separation of vapor and water (vapor enters from the lower part of the valve through the U-shape passage),the inner part of the valve is in water seal state,which effectively prevents the leakage of steam.

6.Water-resistant open floater with gas vent through the bucket's vent,effective to prevent steam locking or air blocking(except the non-confensed high-temperature air).

7.Suitable to be joined with lever mechanism for producing high-pressure valve.
