An Inverted Bucket Trap to Prevent Flash Leakage

Abstract

The invention discloses an inverted bucket type drain valve for preventing flash leakage, which comprises a valve body, on which a gas-liquid separation chamber, a steam inlet channel and a liquid outlet channel are arranged, and a rotating arm is arranged at the bottom of the liquid outlet channel, and the rotating arm An inverted bucket is rotatably connected, and the inverted bucket is covered on the steam inlet channel. An arc-shaped heat-sensitive bimetal sheet is arranged between the liquid outlet channel and the rotating arm, and a valve core is arranged on the arc-shaped heat-sensitive bimetal sheet. One end of the heat-sensitive bimetal sheet is fixed, and the other end is connected with an adjustment sleeve. The adjustment sleeve is rotatably connected with a screw. The temperature-sensitive bimetallic sheet is heated and deformed to block or open the liquid outlet channel of the valve core, and the rotating arm is lifted to push the valve core to block or open the liquid outlet channel. This anti-flash leaking inverted bucket trap effectively prevents steam from rapidly leaking from the outlet channel when the condensed water flashes, so as to achieve the purpose of energy saving and emission reduction.

Description

technical field [0001] The invention belongs to the technical field of steam traps, in particular to an inverted bucket type steam trap for preventing flash leakage. Background technique [0002] Steam traps, also known as automatic drains or condensate drains, are mainly used in steam systems to drain condensate. The anti-flash leakage inverted bucket trap is a commonly used trap. The interior of the anti-flash inverted bucket trap is an inverted bucket as a liquid level sensitive part. The opening of the bucket is downward, and the inverted bucket is connected to a lever to drive the valve. Core opening and closing valve. When the device is just started, air and low-temperature condensed water in the pipeline enter the trap, and the inverted bucket falls by its own weight. The lever connected to the inverted bucket drives the valve core to open the valve, and the air and low-temperature condensed water are quickly discharged. When steam enters the inverted bucket, the st...

Problems solved by technology

In actual use, due to the high temperature of the condensed water in the valve body, when the steam temperature is too high, some condensed water inside the valve body will flash into steam, the inverted bucket loses buoyancy and sinks, and leaks quickly through the outlet Steam, until sufficient condensed water enters the valve body to form a water seal again, can prevent steam leakage and waste, which is not conducive to energy saving and emission reduction
