Description

Technical Field

[0001] The invention specifically relates to a combined sealing device for a heat exchange pipeline and a shell of a fan. Background Art

[0002] A fan heat exchanger is a device used for heat transfer, mainly used to transfer heat from one medium (such as air or water) to another medium. It is usually used in air conditioning systems, HVAC systems, cooling and heating in industrial production processes, etc. In order to prevent gas leakage between the pipeline and the shell, when the fan pipeline is connected to the fan shell, the packing is intermittently put on the pipeline, the sealing ring is pressed with the square plate on the pipeline, and then screwed and fixed, and finally sealant is applied.

[0003] The existing fan heat exchanger pipeline and shell are sealed by packing, which is only subjected to axial force but not radial force, and has a greater risk of leakage. It is also troublesome to apply sealant, and there is also a risk of air leakage. When replacing the clamping device later, due to the bonding and fixation of the glue, the pipeline needs to be cut and replaced, and the pipeline needs to be re-welded after replacement, which is inconvenient for maintenance. For this reason, we propose a combined sealing device for the fan heat exchange pipeline and the shell. Summary of the invention

[0004] The object of the present invention is to provide a combined sealing device for a fan heat exchange pipe and a shell, so as to solve the problems raised in the above-mentioned background technology.

[0011] Preferably, the pressure plate assembly includes a first bottom plate, a second bottom plate, a positioning plate and a second connecting hole. The second bottom plate is arranged side by side with the first bottom plate. The second bottom plate has positioning plates at both ends. The inner side of the positioning plate is provided with a second connecting hole that matches the first bottom plate, and the inner side of the second connecting hole has a first connecting bolt.

[0012] Preferably, a first connecting hole is opened in the middle of the inner side of the first bottom plate, a connecting screw hole is opened on the inner side of the mounting assembly, and the first connecting hole and the connecting screw hole are connected by a second connecting bolt.

[0013] Preferably, the second connecting bolt and the first connecting bolt are staggered with each other, and two of the second connecting bolt and two of the first connecting bolt are provided.

[0014] Preferably, the guide plate and the pressing plate are both semi-annular, and the inner diameter of the guide plate is larger than the outer diameter of the pressing plate.

[0015] Preferably, the mounting assembly is a quadrilateral, and the pressure plate assembly is a pentagon.

[0016] Preferably, at least two packings are arranged side by side along the height direction of the placement groove.

[0017] Preferably, the pressure plate assembly and the mounting assembly are both made of aluminum alloy.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] By providing an installation assembly, a second connecting bolt, a guide plate and a clamping plate, the traditional sealing packing is prevented from being subjected to only axial force but not radial force, resulting in poor sealing effect, the need to apply sealant, and the need to cut the pipeline for replacement later, which is inconvenient to maintain. The device has a simple structure and is designed to be detachable. It can install multiple layers of packing and can well compress the packing to fit it tightly against the fan casing. After sealing, the packing can be subjected to axial and radial forces at the same time, reducing the risk of leakage of the packing seal. It is also easy to quickly replace the packing seal in the later stage, which is convenient for maintenance and increases the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS
