疏水閥,的根本作用是將蒸汽系統(tǒng)中的凝結(jié)水、空氣和二氧化碳氣體盡快排出;同時很大限度地自動避免蒸汽的走漏。疏水閥的種類很多,各有不同的性能。選型、裝置適宜的疏水閥只需有蒸汽經(jīng)過,就不會呈現(xiàn)冰凍問題。
The fundamental function of the steam trap is to discharge the condensate, air and carbon dioxide gas in the steam system as soon as possible; At the same time, it can automatically avoid steam leakage to a great extent. There are many kinds of traps, each with different performance. The steam trap with appropriate type selection and device only needs steam to pass through, so there will be no freezing problem.
但是假如蒸汽斷了,蒸汽凝結(jié)水就會在熱交流器或伴管里構(gòu)成真空。這就會在發(fā)作冰凍之前阻止凝結(jié)水從系統(tǒng)中自在排放進來。所以,要在被排放設(shè)備和疏水閥之間裝置一個真空毀壞器。假如從疏水閥到回水管不是運用重力排放。
However, if the steam is cut off, the steam condensate will form a vacuum in the heat exchanger or companion pipe. This will prevent condensate from draining freely from the system before freezing occurs. Therefore, a vacuum breaker should be installed between the discharged equipment and the drain valve. If gravity is not used to discharge from the drain valve to the return pipe.
疏水閥和排放管線就應(yīng)該用人工排放或者運用帶防凍措施的排放管自動排放。還有,當(dāng)多個疏水閥一同裝置在疏水閥站的時分,給疏水閥保溫能夠避免冰凍。疏水閥防凍措施有疏水閥不要選擇尺寸過大。
The drain valve and discharge pipeline should be discharged manually or automatically by using the discharge pipe with anti freezing measures. In addition, when multiple traps are installed in the trap station together, keeping the trap warm can avoid freezing. Antifreeze measures for drain valves. Do not select too large a drain valve.
堅持疏水閥排放管線盡可能短。向下傾斜疏水閥排放管線,讓重力排放的速度加速。疏水閥排放管線和凝結(jié)水回水管線加保溫。當(dāng)凝結(jié)水回水管線暴露在大氣條件下時,應(yīng)思索加伴熱管。假如回水管升高,垂直排放管要與回水集管上部的排放管相鄰,并把排放管和疏水閥排放管一同保溫。
Keep the drain line of the drain valve as short as possible. Tilt down the drain line of the drain valve to accelerate the gravity discharge. The drain pipeline of steam trap and condensate return pipeline shall be insulated. When the condensate return pipeline is exposed to atmospheric conditions, heat tracing pipe shall be considered. If the return pipe rises, the vertical discharge pipe shall be adjacent to the discharge pipe at the upper part of the return header, and the discharge pipe and the drain valve discharge pipe shall be insulated together.
