Description
Technical Field
The invention belongs to the technical field of drain valves, and particularly relates to an inverted bucket type drain valve capable of preventing flash evaporation and leakage.
Background
Trap valves, also known as automatic drains or condensate drains, are used primarily in steam systems to drain condensate. The inverse hanging bucket type drain valve for preventing flash leakage is a common drain valve, an inverse hanging bucket is arranged in the inverse hanging bucket type drain valve for preventing flash leakage and is a liquid level sensing element, the opening of the hanging bucket is downward, and the inverse hanging bucket is connected with a lever to drive a valve core to open and close a valve. When the device is just started, air and low-temperature condensed water in the pipeline enter the drain valve, the inverted bucket falls down by the weight of the inverted bucket, the inverted bucket is connected with the lever to drive the valve core to open the valve, and the air and the low-temperature condensed water are quickly discharged. When steam enters the inverted bucket, the steam of the inverted bucket generates upward buoyancy, and the inverted bucket rises to be connected with the lever to drive the valve core to close the valve. The inverted bucket is provided with a small hole, when one part of steam is discharged from the small hole and the other part of steam generates condensed water, the inverted bucket loses buoyancy and sinks downwards by the self weight, and the inverted bucket is connected with a lever to drive a valve core to open a valve, so that the inverted bucket works circularly and discharges water discontinuously. When the inverted bucket type drain valve for preventing flash and leakage is used, enough water must be contained in the valve body, a water seal is formed above the lower edge of the inverted bucket, and if the water seal is lost, steam can be directly discharged through the valve outlet. In the in-service use process, because the comdenstion water temperature in the valve body is high, under the too high condition of steam temperature, can make some comdenstion water flash evaporation of valve body inside become steam, the bucket of falling hangs and loses buoyancy and sinks, through the quick leakage steam of export, until having sufficient comdenstion water to get into the interior water seal that reforms formation of valve body again, can prevent steam leakage extravagant, be unfavorable for energy saving and emission reduction.
