其中,第一水室1一端通过连箱管9与凝结水箱10连接,另一端通过一根第一耐温软管4与第二水室2连接,第二水室2通过一根第二耐温软管5与第三水室3连接。第一耐温软管4的长度大于第一水室1与第二水室2之间高度差的最大值H1max。第二耐温软管5的长度大于第二水室2与第三水室3之间高度差的最大值H2max。导杆6垂直设置在地面上。第二水室2及第三水室3与导杆6活动连接,且第三水室3位于第二水室2的上端。充水和泄水管7与第二水室2连接。排气和溢流管8与第三水3室连接。第一水室及第三水室的容积均大于第二水室的容积。Among them, one end of the first water chamber 1 is connected to the condensate tank 10 through the connecting pipe 9, and the other end is connected to the second water chamber 2 through a first temperature-resistant hose 4, and the second water chamber 2 is connected through a second resistant The warm hose 5 is connected with the third water chamber 3 . The length of the first temperature-resistant hose 4 is greater than the maximum value H 1max of the height difference between the first water chamber 1 and the second water chamber 2 . The length of the second temperature-resistant hose 5 is greater than the maximum value H 2max of the height difference between the second water chamber 2 and the third water chamber 3 . Guide rod 6 is vertically arranged on the ground. The second water chamber 2 and the third water chamber 3 are movably connected with the guide rod 6 , and the third water chamber 3 is located at the upper end of the second water chamber 2 . The water filling and draining pipe 7 is connected with the second water chamber 2 . The exhaust and overflow pipe 8 is connected with the third water chamber. The volumes of the first water chamber and the third water chamber are larger than the volume of the second water chamber.

本实用新型提供的安全水封只有第一水室1的位置固定,而第二水室2和第三水室3的高度则可在导杆6上调整,以满足凝结水箱10内不同温度凝结水对压力的要求。当凝结水温度低时,凝结水的沸点压力也较低,也就是和大气压力差较大,可以有较大的真空度,凝结水也不沸腾,此时可以调低第二水室2,把第一水室1与第二水室2之间的高度差H1(以下用H1表示)数值设定较大。当凝结水温度高时,凝结水的沸点压力也较高,也就是和大气压力差变小,需要较小的真空度,才能避免凝结水沸腾,此时可以调高第二水室2,把H1数值设定较小。根据凝结水温度对压力的要求,通过相应调整H1的高度,保障凝结水箱10内的凝结水不沸腾且水封不被冲破,空气就不能进入凝结水箱10,从而保障凝结水泵的稳定运行。In the safety water seal provided by the utility model, only the position of the first water chamber 1 is fixed, while the heights of the second water chamber 2 and the third water chamber 3 can be adjusted on the guide rod 6 to meet the different temperature condensation requirements in the condensate tank 10. water pressure requirements. When the temperature of the condensed water is low, the boiling point pressure of the condensed water is also relatively low, that is, the pressure difference with the atmospheric pressure is relatively large, and the degree of vacuum can be relatively large, and the condensed water does not boil. At this time, the second water chamber 2 can be lowered. The height difference H 1 (hereinafter referred to as H 1 ) between the first water chamber 1 and the second water chamber 2 is set to be larger. When the temperature of the condensed water is high, the boiling point pressure of the condensed water is also higher, that is, the pressure difference with the atmospheric pressure becomes smaller, and a smaller vacuum degree is required to avoid boiling of the condensed water. At this time, the second water chamber 2 can be adjusted to The value of H 1 is set to be small. According to the pressure requirements of the condensed water temperature, by adjusting the height of H1 accordingly, it is ensured that the condensed water in the condensed water tank 10 does not boil and the water seal is not broken, and the air cannot enter the condensed water tank 10, thereby ensuring the stable operation of the condensed water pump.

在保障凝结水箱10安全压力的前提下,尽可能的调整第三水室3的高度,避免第三水室3被频繁冲破,造成凝结水箱内闪蒸蒸汽的排放浪费。当第三水室3处于导杆6的最高处时,第二水室2与第三水室3之间的高度差为H2最大值H2max,此时本实用新型实施例提供的安全水封使凝结水箱10达到的最大密封压力,保证凝结水箱10内闪蒸蒸汽不会外泄。当第二水室2处于导杆6的最底端时,第一水室1与第二水室2之间高度差的达到最大值H1max,此时,安全水封使凝结水箱10内达到最低压力值。安全水封在使用过程时,根据不同的凝结水温度,通过调整H1的高度来调节凝结水箱10内的最小压力值,使凝结水不沸腾,确保凝结水泵运行安全稳定。Under the premise of ensuring the safety pressure of the condensate tank 10, the height of the third water chamber 3 should be adjusted as much as possible to avoid the third water chamber 3 from being frequently breached, resulting in wasteful discharge of flash steam in the condensate tank. When the third water chamber 3 is at the highest point of the guide rod 6, the height difference between the second water chamber 2 and the third water chamber 3 is H 2 maximum value H 2max . Seal the maximum sealing pressure that the condensed water tank 10 reaches to ensure that the flash steam in the condensed water tank 10 will not leak out. When the second water chamber 2 is at the bottom end of the guide rod 6, the height difference between the first water chamber 1 and the second water chamber 2 reaches the maximum value H 1max , at this time, the safety water seal makes the condensation water tank 10 reach Minimum pressure value. When the safety water seal is in use, the minimum pressure value in the condensate tank 10 is adjusted by adjusting the height of H1 according to different condensate temperatures, so that the condensate does not boil and ensures the safe and stable operation of the condensate pump.

第一水室1和第三水室3的容积都大于第二水室2的容积,当凝结水箱10出现真空,第一水室1的水封被冲破,第二水室2中的水会蓄存在第一水室1内。当凝结水箱10内压力升高,水从第一水室1流至第二水室2;若第三水室3水封被冲破,水会蓄存在第三水室3内,当凝结水箱10内压力降低,水从第三水室3流回第二水室2。这样可以使本实施例提供的安全水封能够一次注水,长期使用。The volumes of the first water chamber 1 and the third water chamber 3 are both greater than the volume of the second water chamber 2. When the condensate tank 10 is vacuumed, the water seal of the first water chamber 1 is broken, and the water in the second water chamber 2 will Stored in the first water chamber 1. When the pressure in the condensed water tank 10 rises, water flows from the first water chamber 1 to the second water chamber 2; if the water seal of the third water chamber 3 is broken, the water will be stored in the third water chamber 3. The internal pressure decreases, and the water flows back from the third water chamber 3 to the second water chamber 2 . In this way, the safety water seal provided by this embodiment can be filled with water once and used for a long time.

本实施例提供的安全水封和大气之间的连通是通过排气和溢流管8。当凝结水泵出现故障不能启动时,多余的凝结水将会通过排气和溢流管8溢流出来,依旧能保障凝结水箱10的正常进水。The communication between the safety water seal provided by this embodiment and the atmosphere is through the exhaust and overflow pipe 8 . When the condensed water pump breaks down and cannot be started, excess condensed water will overflow through the exhaust and overflow pipe 8, and the normal water intake of the condensed water tank 10 can still be guaranteed.

为了更清楚的描述本实用新型所提供的一种安全水封,下面从使用方法角度予以阐述。In order to describe the safety water seal provided by the utility model more clearly, it will be explained from the perspective of the use method below.

本实施例提供的安全水封在使用前,先通过充水和泄水管7把第二水室2充满水。使用时,当凝结水箱10和大气压力相等时,第二水室2和第一耐温软管4的水位等高。当凝结水箱10内的压力不断升高时,第二水室2内的水就不断的流向第三水室3,当凝结水箱10内的压力高于第二水室2与第三水室3之间的某一高度差H2产生的水压时,第三水室3的水封被冲破,第二水室2内的水会流入第三水室3,但由于第三水室3的容积大于第二水室2的容积,水会被蓄存在第三水室3,而不会被溢出浪费。当凝结水泵抽水时,凝结水箱10内压力下降,第三水室3内的水回流至第二水室2,当凝结水箱10内降至大气压时,第二水室2和第一耐温软管4的水位等高。随着凝结水泵的抽取,凝结水箱10内逐渐出现负压,第二水室2内的水位下降,第一耐温软管4内的水逐渐流至第一水室1,当凝结水箱10内的压力与大气压的差值大于第一水室1与第二水室2之间的最大高度差H1max产生的水压时,第一水室1水封被冲破,第二水室2内的水不断流入第一水室1,但由于第一水室1的容积大于第二水室2的容积,水会被蓄存在第一水室1,而不会流入凝结水箱10。第一水室1的位置固定,而第二水室2可在导杆6上上下滑动,根据凝结水的温度,通过不断调整高度,来调整凝结水箱10内的压力值,避免凝结水箱10的压力过低导致凝结水沸腾,从而影响水泵的安全稳定运行。而第三水室3也可在导杆6上上下滑动,根据凝结水的温度,通过不断调整高度,来调整凝结水箱10内的压力值,在保障凝结水箱10安全的条件下,尽可能的避免第三水室3被冲破,导致闪蒸蒸汽排放浪费。Before the safety water seal provided by this embodiment is used, the second water chamber 2 is filled with water through the water filling and drain pipe 7 . In use, when the condensed water tank 10 is equal to the atmospheric pressure, the water levels in the second water chamber 2 and the first temperature-resistant hose 4 are at the same height. When the pressure in the condensed water tank 10 is constantly rising, the water in the second water chamber 2 will continue to flow to the third water chamber 3. When the pressure in the condensed water tank 10 is higher than that of the second water chamber 2 and the third water chamber 3 When the water pressure generated by a certain height difference H2 between them, the water seal of the third water chamber 3 is broken, the water in the second water chamber 2 will flow into the third water chamber 3, but due to the third water chamber 3 The volume is larger than that of the second water chamber 2, and the water will be stored in the third water chamber 3 without being overflowed and wasted. When the condensed water pump pumps water, the pressure in the condensed water tank 10 drops, and the water in the third water chamber 3 flows back to the second water chamber 2. When the condensed water tank 10 drops to atmospheric pressure, the second water chamber 2 and the first temperature-resistant soft The water level of pipe 4 is equal. With the extraction of the condensate pump, negative pressure gradually appears in the condensate tank 10, the water level in the second water chamber 2 drops, and the water in the first temperature-resistant hose 4 gradually flows to the first water chamber 1. When the condensate tank 10 When the difference between the pressure and the atmospheric pressure is greater than the water pressure generated by the maximum height difference H 1max between the first water chamber 1 and the second water chamber 2, the water seal of the first water chamber 1 is broken, and the water in the second water chamber 2 Water continuously flows into the first water chamber 1 , but since the volume of the first water chamber 1 is greater than that of the second water chamber 2 , the water will be stored in the first water chamber 1 instead of flowing into the condensation water tank 10 . The position of the first water chamber 1 is fixed, while the second water chamber 2 can slide up and down on the guide rod 6. According to the temperature of the condensed water, the pressure value in the condensed water tank 10 can be adjusted by continuously adjusting the height, so as to avoid the condensation of the condensed water tank 10. If the pressure is too low, the condensed water will boil, which will affect the safe and stable operation of the pump. The third water chamber 3 can also slide up and down on the guide rod 6. According to the temperature of the condensed water, the pressure value in the condensed water tank 10 can be adjusted by continuously adjusting the height. Under the condition of ensuring the safety of the condensed water tank 10, the Prevent the third water chamber 3 from being breached, resulting in waste of flash steam discharge.

当凝结水泵出现故障不能启动时,多余的凝结水将会通过排气和溢流管8溢流出来,依旧能保障凝结水箱10的正常进水。When the condensed water pump breaks down and cannot be started, excess condensed water will overflow through the exhaust and overflow pipe 8, and the normal water intake of the condensed water tank 10 can still be guaranteed.

本实用新型提供的安全水封,结构简单,部件之间连接方便,一次注水,长期使用,通过调整第二水室和第三水室的高度,来控制凝结水箱内的压力,最大可能的保障凝结水泵的稳定运行和减少凝结水箱内闪蒸蒸汽的排放,有效的降低了企业的生产成本,提高了生产效益。The safety water seal provided by the utility model has simple structure, convenient connection between components, one-time water injection, and long-term use. By adjusting the height of the second water chamber and the third water chamber, the pressure in the condensate tank is controlled to ensure the greatest possible protection. The stable operation of the condensate pump and the reduction of the discharge of flash steam in the condensate tank effectively reduce the production cost of the enterprise and improve the production efficiency.
