Description

Technical Field

[0001] The utility model relates to the technical field related to steam traps, in particular to a steam trap group which is easy to install. Background Art

[0002] When the reactor is heated by steam, the steam passes through the reactor jacket and directly collects the condensed water into another reactor, resulting in low heat exchange efficiency and large energy waste.

[0003] To ensure its thermal efficiency, when the reactor is heated by steam, a steam trap group is added after the steam passes through the reactor jacket, so that it can control the steam in the reactor jacket at a certain pressure, thereby increasing the heat exchange efficiency and high energy utilization rate.

[0004] Existing steam trap groups are usually connected and fixed using bolts. Since most of the steam trap groups are movable, when emergency treatment is required, the steam trap group needs to be disassembled. Due to the use of bolt connections, the operation is inconvenient and time-consuming. Utility Model Content

[0005] The utility model aims to overcome the disadvantage of inconvenient installation and operation in the prior art and provides a steam trap group that is easy to install and has simple and convenient installation and operation.

[0007] This trap assembly includes a trap body with trap flanges at both ends. These flanges are used to connect to the reactor's pipeline. When the reactor is heated using steam, the steam passes through the reactor's jacket and enters the trap body. The trap body controls the steam pressure within the reactor jacket, thereby increasing heat exchange efficiency and improving energy utilization. The trap flanges are provided with several evenly spaced, arc-shaped connecting grooves. Furthermore, the end faces of the trap flanges are provided with sliding grooves, within which an adjustment rod is slidably connected. The rod can slide within the grooves and, by rotating the rod, can be locked, thereby securing the rod. A connecting piece is connected to the adjusting rod, and a locking rod is connected to the end of the connecting piece. The locking rod can be inserted into the connecting groove to lock the hydrophobic flange and the reactor pipe. At the same time, the adjusting rod can ensure that the locking rod is stably inserted into the connecting groove by adjusting its position, thereby ensuring the locking effect. When disassembling, it is only necessary to move the position of the adjusting rod to complete the removal of the locking rod from the connecting groove to achieve disassembly. This structure facilitates the disassembly and assembly of the hydrophobic valve group and makes the operation simple and convenient.

[0010] Preferably, the adjustment rod is embedded in a sliding groove, which is an arc-shaped groove. A limit ring is provided in the middle of the adjustment rod, which engages with the inner wall of the sliding groove, and the bottom surface of the adjustment rod contacts the bottom surface of the sliding groove. A limit ring is provided on the side wall of the adjustment rod to limit the adjustment rod, ensuring that the adjustment rod is always within the sliding groove. This structure facilitates adjustment of the adjustment rod, thereby ensuring simple and convenient operation.

[0011] Preferably, the top of the adjusting rod is provided with a cross slot for rotating the adjusting rod. The cross slot provided on the top of the adjusting rod is convenient for rotating with a tool, thereby facilitating the disassembly of the steam trap group and making the operation simple and convenient.
