A self-priming inverted bucket trap

Abstract

The invention discloses a self-priming inverted bucket type steam trap, 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 is connected by rotation. There is an inverted bucket, the inverted bucket is covered on the steam inlet channel, and the valve core is arranged on the rotating arm, and the inverted bucket is lifted to make the valve core block or open the liquid outlet channel, and the steam inlet channel is sequentially provided with a tapered guide along the steam flow direction section, injection area and vacuum chamber, the vacuum chamber is connected with a self-priming channel, a check valve is arranged on the self-priming channel, and the self-priming channel is connected with a water container. When the condensed water flashes into steam in this self-priming inverted bucket trap, the steam flow rate is significantly accelerated. When the steam passes through the conical guide section, injection area and vacuum chamber quickly, the vacuum chamber will generate greater suction. The water in the water container is sucked into the vacuum chamber, and enters the valve body to quickly form a water seal, preventing a large amount of steam from leaking and wasting, which is conducive to energy saving and emission reduction.

Description

technical field [0001] The invention belongs to the technical field of drain valves, in particular to a self-priming inverted bucket drain valve. Background technique [0002] Steam traps, also known as automatic drains or condensate drains, are mainly used in steam systems to drain condensate. The inverted bucket trap is a commonly used steam trap. Inside the inverted bucket trap is an inverted bucket as a liquid level sensitive part. The opening of the bucket is downward, and the connecting lever of the inverted bucket drives the valve core to open and close the 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 steam in the inverted bucket generates upward buoyancy, a...

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
