Description

Technical Field

[0001] This utility model relates to the field of refrigeration system technology, and in particular to a pipeline vibration damping structure for a cold storage refrigeration system. Background Technology

[0002] In cold storage refrigeration systems, the welding of pipes between the compressor and condenser is a crucial step in ensuring system sealing and efficient operation. Copper pipes are typically used to connect the compressor and condenser due to their excellent thermal conductivity and corrosion resistance. A specialized pipe cutter is used to cut the copper pipes, avoiding uneven cuts or metal shavings. Before welding, the welding area must be sanded until the natural copper color is visible, and oil, oxides, and other impurities must be removed. High-purity nitrogen must be continuously introduced during welding to prevent the copper pipe's inner wall from oxidizing at high temperatures and forming oxide scale, which would affect system operation. A strong flame is used for rapid welding to shorten the welding time and prevent oxide buildup. The pipe diameters of the compressor exhaust port and condenser inlet must be strictly matched; if the distance is long, the pipe diameter must be increased. Copper pipes of the same diameter are used for sleeve welding; after flaring, another pipe is inserted, and the insertion depth must be appropriate.

[0003] For pipes between the compressor and condenser that use sleeve welding, a vibration damping structure is needed to prevent the weld points from cracking.

[0004] The existing pipe vibration damping structure of the cold storage refrigeration system has been found to have shortcomings during use. First, it lacks its own vibration damping design; second, its external vibration damping support is poorly designed, which can easily lead to pipe deformation under pressure.

[0005] Therefore, it is necessary to optimize and improve the existing pipe vibration damping structure used in cold storage refrigeration systems. Summary of the Invention

[0006] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and provide a pipe vibration damping structure for cold storage refrigeration systems.

[0007] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0008] A pipe vibration damping structure for a cold storage refrigeration system includes a mounting base, gel boxes, a slide rail, sliders, uprights, clamping components, a screw, a screw sleeve, and refrigeration pipes. The refrigeration pipes are formed by connecting two branch pipes by sleeve welding. The two branch pipes are respectively connected to the compressor and the condenser. Each branch pipe is pre-bent near the weld to form an outer U-shaped tube section and an inner U-shaped tube section. Two gel boxes and a slide rail located between the two are fixed on the upper side of the mounting base. Each gel box has an insertion hole on its upper plate to facilitate the insertion of the corresponding outer U-shaped tube section. After the outer U-shaped tube section is inserted, the gel box is filled with a three-dimensional damping organic gel to provide damping function. Two sliders slide on the slide rail. An upright is fixed on the upper side of the slider. Each upright is equipped with a clamping component on its outer side for clamping the inner rod of the corresponding inner U-shaped tube section. A screw is fixed on the inner side of one upright, and a screw sleeve sleeve sleeved on the outer side of the screw is movably supported on the inner side of the other upright.

[0009] Furthermore, in the above-mentioned pipe vibration damping structure for cold storage refrigeration system, the mounting base plate has mounting holes at both ends to facilitate its installation on the refrigeration base.

[0010] Furthermore, in the above-mentioned pipe vibration damping structure for cold storage refrigeration system, each of the outer U-shaped pipe section and the inner U-shaped pipe section is arranged side by side.

[0011] Furthermore, in the above-mentioned pipe vibration damping structure for cold storage refrigeration systems, the three-dimensional barrier organic gel is selected as an organosilicon gel that is easy to cure at room temperature.

[0012] Furthermore, in the above-mentioned pipe vibration damping structure for cold storage refrigeration system, a limiting structure to prevent jumping is provided between the slide rail and the slider.

[0013] Furthermore, in the above-mentioned pipe vibration damping structure for cold storage refrigeration system, the clamping component consists of two clamping plates and fasteners. Each clamping plate includes a clamping plate body. One end of the clamping plate body is provided with a hinge joint, and the other end is provided with a fastening hole that mates with the fasteners. The clamping plate body is provided with an arc-shaped protrusion. An arc-shaped anti-pressure pad that mates with the outer diameter of the inner rod in the inner U-shaped tube section is installed on the inner side of the arc-shaped protrusion.

[0014] Furthermore, in the above-mentioned pipe vibration damping structure for cold storage refrigeration system, the inner end of the screw sleeve is provided with a T-shaped rotating head, the vertical plate where the screw sleeve is located is provided with a movable cavity that cooperates with the T-shaped rotating head, and the outer end of the movable cavity is equipped with an annular cover plate to prevent the T-shaped rotating head from disengaging.

[0015] Furthermore, in the above-mentioned pipe vibration damping structure for cold storage refrigeration system, the insertion depth of the two branch pipes in the refrigeration pipeline before welding is adjusted by the screwing operation of the screw sleeve on the screw.

[0016] The beneficial effects of this utility model are:

[0017] This utility model features a rationally designed structure, primarily composed of a mounting base, a gel box, a slide rail, a slider, a vertical plate, a clamping component, a screw, a screw sleeve, and refrigeration piping. By pre-bending two branch pipes of the refrigeration piping to form outer and inner U-shaped sections, a damping system is constructed using the gel box and the three-dimensional damping organic gel filling it, providing reliable vibration reduction for the two outer U-shaped sections. A clamping system, consisting of the slide rail, slider, vertical plate, clamping component, screw, and screw sleeve, locks the relative positions of the two inner U-shaped sections, preventing cracking at the weld position due to vibration after sleeve welding. Furthermore, this clamping system provides clamping functionality before sleeve welding. The insertion depth of the two branch pipes in the refrigeration piping is adjusted by screwing the screw sleeve onto the screw, facilitating sleeve welding. Locking is achieved automatically after sleeve welding without additional operation.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

The two branch pipes 101 are pre-bent near the welding point to form an outer U-shaped pipe section 102 and an inner U-shaped pipe section 103.

[0031] In this embodiment, two gel boxes 2 and a slide rail 4 located between them are fixed on the upper side of the mounting base 1. Each gel box 2 has an insertion hole on its upper plate to facilitate the insertion of the corresponding outer U-shaped tube 102.

[0033] In this embodiment, the outer U-shaped tube section 102 and the inner U-shaped tube section 103 are arranged side by side.

[0034] In this embodiment, the stereo-impeding organic gel 3 is selected as an organosilicon gel that is easy to cure at room temperature, or other organic gels that have damping function after curing at room temperature can also be selected.

[0035] In this embodiment, a limiting structure to prevent jumping is provided between the slide rail 4 and the slider 5.

[0036] In this embodiment, the clamping member 7 consists of two clamping plates and fasteners. Each clamping plate includes a clamping plate body 701.

The clamping system formed by the slide rail 4, slider 5, vertical plate 6, clamping component 7, screw 8, and screw sleeve 9 can lock the relative positions of the two inner U-shaped tube sections 103, thereby preventing cracking of the welded position due to vibration after the sleeve is welded. Meanwhile, the clamping system can also provide clamping function before sleeve welding. By screwing the sleeve 9 onto the screw 8, the insertion depth of the two branch pipes 101 in the refrigeration pipeline 10 can be adjusted before welding, which facilitates sleeve welding.
