Description

Technical Field

[0001] The utility model relates to the technical field of pipeline baffle doors, in particular to a steam jacketed baffle door. Background Art

[0002] The baffle door is a common component in industrial pipelines. Its main function is to adjust the air volume of the system. During maintenance, the pipeline system is closed to prevent airflow. When the main pipeline system is in normal operation, the baffle door is in the open state. At this time, the baffle door of the bypass system is closed. Under special working conditions, it is necessary to close the baffle door of the main pipeline system and open the baffle door of the bypass system for switching.

[0003] The corresponding medium components in the airflow contain sticky substances such as tar. After long-term circulation, the sticky medium accumulates and adheres to the baffle blades and baffle valve positions. Sometimes the baffle valve in the closed state cannot be opened, and rapid switching under special working conditions cannot be achieved. Manual cleaning of the sticky medium is required on a regular basis, and even replacement of the baffle blades and baffle valves is required, resulting in a waste of manpower and material resources.

A baffle blade 4 is provided at the outlet of the baffle door 1. The baffle blade 4 is cut and formed by steel plates and assembled. The executive structure 2 drives the baffle blade 4 to rotate around the axis to open or close the baffle door 1. The steam jacket 3 is wound around the outside of the shell 5 of the baffle door 1 and contacts with the executive structure 2. A steam chamber 6 for circulating steam is provided inside the steam jacket 3. A steam inlet 7 and an air vent 8 are provided at the top of the steam jacket 3. The steam inlet 7 and the air vent 8 are connected to the steam chamber 6.

[0025] Reference Figure 1 、 Figure 5 The steam jacket 3 includes two side panels 9 vertically connected to the shell 5, and the steam chamber 6 is set between the two side panels 9. A pressure strip 10 is fixedly installed on the top of the side panel 9 and fastened by bolts 11, so that the steam chamber 6 is attached to the outside of the shell 5 of the baffle door 1 and heats the baffle door 1.

[0026] Reference Figure 1 、 Figure 3 、 Figure 5 Fixing bolts 19 are arranged at intervals along the winding direction of the steam jacket 3. The fixing bolts 19 fix the steam jacket 3 to the shell 5 of the baffle door 1, thereby fixing the steam jacket 3 and the steam chamber 6.

[0027] Reference Figure 1 A drain outlet 12 is provided at the bottom of the steam jacket 3. The steam flowing in the steam chamber 6 forms condensed water after cooling, and the condensed water is discharged at the drain outlet 12 to prevent accumulation in the steam chamber 6.
