Description

Technical Field

[0001] The utility model relates to the technical field of a steam trap, in particular to an exhaust structure of a steam trap. Background Art

[0002] A steam trap is a valve, also known as a steam trap and a drain valve. A steam trap is a device used to remove condensed water and non-condensable gases (such as steam) accumulated in pipes or equipment. A steam trap plays an important role in the industrial field. It can effectively remove condensed water in the system and keep the system running normally. The basic principle of a steam trap is to use the physical properties of water at different temperatures to discharge condensed water from the system in time through automatic or manual control. This can avoid condensed water blocking pipes or causing water hammer and other problems. It can also improve the heat transfer efficiency and energy utilization of the system. However, existing steam traps may accumulate air or other non-condensable gases during operation. If these gases are not discharged, the normal operation of the steam trap will be affected. Therefore, a person skilled in the art provides an exhaust structure of a steam trap to solve the problems raised in the above background technology. Utility Model Content

[0003] The utility model aims to provide an exhaust structure of a steam trap to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A steam trap exhaust structure comprises a water inlet pipe, a water inlet water supply pipe is arranged at the right end of the water inlet pipe, a valve slot water inlet is arranged at the upper end of the water inlet water supply pipe, a valve slot is arranged at the upper end of the valve slot water inlet, an inverted bucket is arranged on the outer side of the valve slot water inlet, an air leakage hole is arranged on the upper left side of the inverted bucket, and an exhaust pipe is arranged at the upper end of the valve slot.

[0006] Preferably, an exhaust pipe is provided on the right side of the upper end of the exhaust duct, a control rod is provided on the left end of the exhaust pipe, a sealing gasket is provided on the right side of the control rod, springs are provided on the outsides of the exhaust pipe, the control rod and the sealing gasket, a float bucket is provided on the lower left end of the control rod, an inverted bucket connecting piece is provided on the upper end of the inverted bucket, a water outlet valve slot is provided on the upper right end of the valve slot, and a connecting rod connecting piece is provided on the lower right side of the water outlet valve slot.

[0007] Preferably, a connecting rod is provided between the inverted bucket connecting piece and the connecting rod connecting piece, a water outlet valve block is provided at the upper end of the connecting rod corresponding to the water outlet valve groove, a water outlet water supply pipeline is provided on the upper side of the water outlet valve groove, a water outlet pipeline is provided at the other end of the water outlet water supply pipeline, and flange connecting blocks are provided on the outer sides of the water inlet pipeline and the water outlet pipeline.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the flange connection blocks at the left and right ends of the steam trap are connected with the external pipeline, the condensate flows in from the water inlet pipeline, the condensate then enters the valve slot from the water inlet pipeline through the valve slot water inlet, the condensate enters the inverted bucket to establish a water seal, the condensate fills the valve slot, the float bucket floats up, the spring drives the control rod and the sealing gasket to seal the exhaust pipe to prevent the condensate from leaking, the condensate then flows out from the water outlet valve slot in the valve slot, flows into the water outlet water delivery pipeline, and the condensate finally enters the water outlet pipeline When the steam enters from the water inlet pipe, it flows into the inverted bucket of the valve slot through the water inlet pipe. The steam generates buoyancy on the inverted bucket. A leakage hole is arranged on the upper left side of the inverted bucket. The leakage hole slowly leaks the steam. The inverted bucket floats up and drives the connecting rod to move. The other end of the connecting rod is movably fixed on the connecting rod connecting piece. The movement of the connecting rod drives the water outlet valve block to block the water outlet valve slot. Condensed water and steam cannot go out through the water outlet valve slot. When the water inlet pipe no longer enters the steam, the steam in the inverted bucket slowly flows out from the leakage hole. When the air hole leaks out, the inverted bucket sinks, and the inverted bucket drives the connecting rod to move downward. The connecting rod drives the water outlet valve block out of the water outlet valve groove, and the condensate recovers and flows out from the water outlet valve groove. The moisture in the steam melts into the condensate and flows out. The non-condensable gas enters the exhaust pipe and gathers at the top of the exhaust pipe. When the non-condensable gas gathers to a certain amount, the condensate in the exhaust pipe decreases, and the float bucket is driven to move downward by the condensate. The float bucket drives the control rod to move downward, and the control rod drives the spring to bend, and the sealing gasket at the right end of the control rod is separated from the exhaust pipe, and the non-condensable gas is discharged from the exhaust pipe. When the non-condensable gas is discharged, the condensate drives the float bucket to move upward and recover, and the float bucket and the spring drive the control rod to return to their original position. The control rod drives the sealing gasket at the right end to seal the exhaust pipe, completing the exhaust of the steam trap. By automatically discharging the non-condensable gas in the steam trap, the accumulation of non-condensable gas may cause unstable pressure in the pipeline system and affect the normal operation of the system. By automatically discharging these gases, the stability of the system can be maintained to ensure its normal operation. BRIEF DESCRIPTION OF THE DRAWINGS
