自在半浮球式疏水閥是如何進(jìn)行工作的?

當(dāng)設(shè)備剛發(fā)動時,管道內(nèi)的空氣和低溫凝聚水通過發(fā)射管進(jìn)入疏水閥內(nèi),閥內(nèi)的雙金屬片排空元件把球桶彈開,閥門敞開,空氣和低溫凝聚水敏捷排出。當(dāng)蒸汽進(jìn)入球桶內(nèi),球桶發(fā)生向上浮力,一起閥內(nèi)的溫度升高,雙金屬片排空元件縮短,球捅漂向閥口,閥門封閉。當(dāng)球桶內(nèi)的蒸汽變成凝聚水,球桶失掉浮力往下沉,閥門敞開,凝聚水敏捷排出。當(dāng)蒸汽再進(jìn)入球桶之內(nèi),閥門再封閉,接連和接連作業(yè)。
When the equipment is just started, the air and low-temperature condensed water in the pipeline enter the drain valve through the launching pipe. The bimetallic sheet emptying element in the valve pops the ball barrel open, the valve opens, and the air and low-temperature condensed water are discharged quickly. When the steam enters the ball barrel, the ball barrel generates upward buoyancy, the temperature in the valve rises, the bimetallic sheet emptying element shortens, the ball poke floats to the valve port, and the valve is closed. When the steam in the ball barrel becomes condensed water, the ball barrel loses buoyancy and sinks down, the valve opens and the condensed water is discharged quickly. When the steam enters the ball barrel again, the valve will be closed again for continuous and continuous operation.
杠桿浮球式疏水閥基本特色與自在浮球式相同,內(nèi)部結(jié)構(gòu)是浮球銜接杠桿帶動閥心,隨凝聚水的液位升降進(jìn)行開關(guān)閥門。杠桿浮球式疏水閥運(yùn)用雙閥座增加凝聚水排量,可到達(dá)體積小排量大,大疏水量達(dá)100噸/小時,是大型加熱設(shè)備理想的疏水閥。4.倒吊桶式疏水閥:
The basic characteristics of the lever floating ball trap are the same as the free floating ball trap. The internal structure is that the floating ball connects the lever to drive the valve core, and the valve is opened and closed with the rise and fall of the liquid level of condensed water. The lever floating ball drain valve uses double valve seats to increase the condensed water displacement, which can achieve small volume, large displacement and large drainage capacity of 100 tons / hour. It is an ideal drain valve for large heating equipment. 4. Inverted bucket drain valve:
當(dāng)設(shè)備剛發(fā)動時,管道內(nèi)的空氣和低溫凝聚水進(jìn)入疏水閥內(nèi),倒吊桶靠本身分量下墜,倒吊桶銜接杠桿帶動閥心敞開閥門,空氣和低溫凝聚水敏捷排出。當(dāng)蒸汽進(jìn)入倒吊桶內(nèi),倒吊桶的蒸汽發(fā)生向上浮力,倒吊桶上升銜接杠桿帶動閥心封閉閥門。倒吊桶上開有一小孔,當(dāng)一部份蒸汽從小孔排出,另一部份蒸汽發(fā)生凝聚水,倒吊桶失掉浮力,靠本身分量向下沉,倒吊桶銜接杠桿帶動閥心敞開閥門,循環(huán)作業(yè),接連排水。
When the equipment is just started, the air and low-temperature condensed water in the pipeline enter the trap, the inverted bucket falls by its own weight, the inverted bucket connecting lever drives the valve core to open the valve, and the air and low-temperature condensed water are discharged quickly. When the steam enters the inverted bucket, the steam of the inverted bucket generates upward buoyancy, and the inverted bucket rises and the connecting lever drives the valve core to close the valve. A small hole is opened on the inverted bucket. When part of the steam is discharged from the small hole and the other part of the steam generates condensed water, the inverted bucket loses its buoyancy and sinks by its own weight. The inverted bucket is connected with the lever to drive the valve core to open the valve for cyclic operation and continuous drainage.
組合式過熱蒸汽疏水閥有兩個阻隔的閥腔,由兩根不銹鋼管連通上下閥腔,它是由浮球式和倒吊桶式疏水閥的組合,該閥結(jié)構(gòu)先進(jìn)合理,在過熱、高壓、小負(fù)荷的作業(yè)狀況下,可以及時地排放過熱蒸汽消失時構(gòu)成的凝聚水,有用地阻撓過熱蒸汽走漏,作業(yè)質(zhì)量高。高答應(yīng)溫度為600℃,閥體為全不銹鋼,閥座為硬質(zhì)合金鋼,運(yùn)用壽命長,是過熱蒸汽專用疏水閥,填補(bǔ)了國內(nèi)空白。
The combined superheated steam trap has two blocked valve cavities, and the upper and lower valve cavities are connected by two stainless steel pipes. It is a combination of floating ball type and inverted bucket type trap. The structure of the valve is advanced and reasonable. Under the operation conditions of overheating, high pressure and small load, it can timely discharge the condensed water formed when the superheated steam disappears, effectively prevent the leakage of superheated steam, and the operation quality is high. The high allowable temperature is 600 ℃, the valve body is all stainless steel, the valve seat is hard alloy steel, and the service life is long. It is a special steam trap for superheated steam, which fills the gap in China.
