Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of flanged end caps for refrigeration equipment, specifically a flanged end cap for refrigeration equipment. Background Technology
[0002] The main functions of flanged end caps in refrigeration equipment are sealing and pressure bearing. As part of a pressure vessel, the main function of the flanged end cap is to seal the end of the vessel to prevent the internal medium from leaking out, while also bearing the pressure inside the vessel.
[0003] For example, in the case of an internally reinforced flanged end cap with authorization announcement number "CN218595008U", air pressure compresses the convex surface of the end cap, and the pressure is transmitted to the spring through the top plate against the inner top wall of the convex surface. The spring is compressed and generates a reaction force, which can effectively prevent the convex surface of the end cap from deforming. The damper can quickly absorb the vibration generated when the spring is compressed, ensuring the overall stability, thereby improving the strength of the convex surface of the end cap and protecting the convex surface of the end cap when the internal air pressure changes. However, in the use of flanged end caps, the internal support is in the form of a spring. Springs have elasticity. When the spring is compressed, the rebound force generated will cause the support plate to hit the flanged end cap. This will increase the damage to the flanged end cap, shorten its service life, and increase the maintenance cost of the flanged end cap. Utility Model Content
[0004] The purpose of this utility model is to address the problem of shortening the service life of flanged end caps and increasing their maintenance costs, by proposing a flanged end cap for refrigeration equipment.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] Design a flanged end cap for refrigeration equipment, including a housing and a first flange. The top of the housing is fixedly connected to the inner bottom of the first flange. A support structure is connected to the inner wall of the housing. A vertical pipe is connected to the bottom of the housing. A sealing structure is connected to the inner wall of the vertical pipe. A refrigeration equipment is attached to the top of the first flange.
[0007] Preferably, the support structure includes an inner layer and a bracket, the outer wall of the inner layer is fixedly connected to the inner wall of the outer shell, the top of the inner wall of the inner layer is fixedly connected to the end of the bracket, and a vertical rod is fixedly connected to the inner wall of the bracket.
[0008] Preferably, the bottom of the vertical rod is fixedly connected to the bottom of the inner wall of the inner layer.
[0009] Preferably, a second flange is fixed to the bottom of the outer wall of the vertical pipe.
[0010] Preferably, the sealing structure includes a plug and a circular plate. The outer wall of the plug is inserted into the inner wall of the vertical pipe, and the end of the outer wall of the plug is fixed to the inner wall of the circular plate. Bolts are threadedly connected to the upper and lower sides of the outer wall of the circular plate.
[0011] Preferably, the top of the circular plate is fitted to the bottom of the second flange.
[0012] The present invention proposes a flanged end cap for refrigeration equipment, which has the following advantages: by thickening the inner layer of the outer shell in the support structure, and by using its own carbon fiber material, the strength of the outer shell is improved while the weight is reduced. The bracket and vertical rod support the inner layer, thereby increasing its strength. This changes the original elastic support form and improves the strength of the outer shell through the use of strong materials, ensuring the service life of the flanged end cap and reducing the maintenance cost of the flanged end cap.

[0018] The present invention will be further described below with reference to the accompanying drawings:
[0019] Example 1:
[0020] Please see Figure 1-4In this embodiment, a flanged end cap for a refrigeration device includes a housing 1 and a first flange 4. The top of the housing 1 is fixedly connected to the inner bottom of the first flange 4. The housing 1 and the first flange 4 form a flanged end cap. A support structure 2 is connected to the inner wall of the housing 1. A vertical pipe 5 is connected to the bottom of the housing 1. A sealing structure 3 is connected to the inner wall of the vertical pipe 5. A refrigeration device 8 is attached to the top of the first flange 4. How the refrigeration device 8 is operated and used is existing technology and will not be elaborated on. The model is selected according to the usage requirements.
[0021] The support structure 2 includes an inner layer 201 and a bracket 202. The outer wall of the inner layer 201 is fixedly connected to the inner wall of the outer shell 1. The inner layer 201 is made of carbon fiber, which increases strength and reduces weight. The top of the inner wall of the inner layer 201 is fixedly connected to the end of the bracket 202. A vertical rod 203 is fixedly connected to the inner wall of the bracket 202. The bracket 202 and the vertical rod 203 work together to support the inner layer 201. The bottom of the vertical rod 203 is fixedly connected to the bottom of the inner wall of the inner layer 201.
[0022] The inner layer 201 in the outer shell 1 is thickened by the support structure 2. At the same time, the inner layer 201, made of carbon fiber, increases the strength of the outer shell 1 while reducing its weight. The bracket 202 and the vertical rod 203 support the inner layer 201, increasing its strength and changing the original elastic support form. The strength of the outer shell 1 is improved by using high-strength materials, which ensures the service life of the flanged end cap and reduces the maintenance cost of the flanged end cap.
[0023] A second flange 6 is fixedly connected to the bottom of the outer wall of the vertical pipe 5. The sealing structure 3 includes a plug 301 and a circular plate 302. The outer wall of the plug 301 is inserted into the inner wall of the vertical pipe 5. The plug 301 is made of rubber. The end of the outer wall of the plug 301 is fixedly connected to the inner wall of the circular plate 302. Bolts 303 are threadedly connected to the upper and lower sides of the outer wall of the circular plate 302. The bolts 303 fix the circular plate 302 and the second flange 6. The top of the circular plate 302 fits against the bottom of the second flange 6.
[0024] Working principle:
[0025] Install refrigeration equipment using flanged end caps:
[0026] Make the top of the first flange 4 fit with the bottom of the refrigeration equipment 8, and then the screws are threaded through the first flange 4 from bottom to top and fixed to the refrigeration equipment 8 to complete the installation of the flange end cap. The inner layer 201 in the outer shell 1 is thickened. At the same time, the inner layer 201, through its own carbon fiber material, improves the strength of the outer shell 1 and reduces the weight. The bracket 202 and the vertical rod 203 support the inner layer 201, increasing the strength of the inner layer 201.
[0027] Refrigeration equipment is connected to pipes with flanged end caps:
[0028] The bolt 303 is rotated outward through the circular plate 302, causing the outer wall of the bolt 303 to detach from the second flange 6. Then, the circular plate 302 is pulled forward, causing the circular plate 302 to move forward with the plug 301, so that the plug 301 gradually detaches from the interior of the vertical pipe 5. Subsequently, the connection of the external pipe is fitted with the second flange 6. Then, the screws are used to fix the second flange 6 to the external pipe. When the flanged end cap is not connected to the external pipe, the plug 301 acts as a sealant for the vertical pipe 5.
[0029] Example 2:
[0030] Please see Figure 1-4 In this embodiment, a flanged end cap for a refrigeration device also includes a handle 7, the rear end face of which is fixedly connected to the front face of the plug 301.
[0031] Working principle:
[0032] The movable stopper 301 can be gripped and pulled forward by the handle 7. The handle 7 moves the stopper 301 forward, changing the way the circular plate 302 moves the stopper 301. The handle 7 makes it easier for the stopper 301 to move.
[0033] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
