Description
Technical Field
[0001] This utility model relates to the technical field of carbon dioxide pump interface structure, and in particular to a leak-proof interface for a carbon dioxide pump. Background Technology
[0002] The carbon dioxide pump interface is a crucial component connecting the pump to the entire carbon dioxide delivery pipeline system. Different interface designs prioritize ease of installation and disassembly. Common carbon dioxide pump interfaces include threaded interfaces, flange interfaces, compression fitting interfaces, welded interfaces, quick-connect interfaces, and hose interfaces. Selecting the appropriate interface type based on the operating environment and requirements of the carbon dioxide pump allows for better adaptation to various working conditions. Since carbon dioxide is a gaseous medium and prone to leakage, pump interfaces are typically equipped with specialized sealing devices or use sealing materials such as gaskets, sealing rings, and sealant. Their function is to prevent carbon dioxide gas from leaking into the surrounding environment during pump operation. The carbon dioxide pump interface must be compatible with the interfaces of other components in the pipeline system, such as valves, filters, and flow meters.
[0003] The most common interfaces for carbon dioxide pumps are threaded and flanged. In the current technology, carbon dioxide pumps are connected to carbon dioxide delivery pipeline systems through threaded and flanged interfaces. There are several problems with the use of this type of interface. First, the style and specifications of the carbon dioxide pump interface are fixed and cannot be switched between threaded and flanged interfaces. It is also not possible to replace the flange with a different number of through holes as needed, which makes the carbon dioxide pump interface not very adaptable and not conducive to maintenance and replacement. Second, the sealing gasket is easy to slip off the flange surface. Utility Model Content
[0004] The main objective of this invention is to provide a leak-proof interface for a carbon dioxide pump, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A leak-proof interface for a carbon dioxide pump includes an internally threaded sleeve, an externally threaded short pipe movably installed inside the internally threaded sleeve, a flange fixedly installed on the front surface of the internally threaded sleeve, a rounded rubber ring fixedly installed inside the circular groove on the front surface of the flange, and a rubber sealing gasket being fitted inside the rounded rubber ring.
[0007] Preferably, the front and rear surfaces of the rubber sealing gasket are provided with annular grooves.
[0008] Preferably, the internally threaded sleeve includes a connecting sleeve and a threaded groove.
[0009] Preferably, the connecting sleeve is fixedly installed on the rear surface of the flange, and the threaded groove is formed on the inner side of the connecting sleeve at the rear end.
[0010] Preferably, the externally threaded short pipe includes an externally threaded connecting pipe, a first rubber sealing ring, and a second rubber sealing ring.
[0011] Preferably, the external threaded connecting tube is located inside the threaded groove, the first rubber sealing ring is sleeved on the outside of the external threaded connecting tube, the second rubber sealing ring is located inside the threaded groove at the front end, the front surface of the external threaded connecting tube is attached to the rear surface of the second rubber sealing ring, and the front surface of the first rubber sealing ring is attached to the rear surface of the connecting sleeve.
[0012] Preferably, both the No. 1 and No. 2 rubber sealing rings have annular grooves on their outer sides, and the short marking line on the outer side of the connecting sleeve is aligned with the short marking line on the outer side of the external threaded connecting pipe.
[0013] This utility model, through the setting of an internally threaded sleeve, an externally threaded short pipe and a flange, allows the interface of the carbon dioxide pump to be switched between a threaded interface and a flange interface, and allows the flange with a different number of through holes to be replaced, thereby improving adaptability and facilitating maintenance and replacement.
[0014] The rounded rubber ring and rubber sealing gasket make it difficult for the sealing gasket of the leak-proof interface to slip off, which is beneficial for pipeline installation. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] like Figure 1-4 As shown, a leak-proof interface for a carbon dioxide pump includes an internally threaded sleeve 1, with an externally threaded short pipe 2 movably installed inside the internally threaded sleeve 1. A flange 3 is fixedly installed on the front surface of the internally threaded sleeve 1. A rounded rubber ring 4 is fixedly installed inside a circular groove on the front surface of the flange 3. A rubber sealing gasket 5 is fitted inside the rounded rubber ring 4. The rounded rubber ring 4 in the circular groove on the front surface of the flange 3 prevents the rubber sealing gasket 5 from slipping off. The rubber sealing gasket 5 serves a sealing function. The internally threaded sleeve 1, together with the externally threaded short pipe 2 and the flange 3, allows the interface of the carbon dioxide pump to be switched between a threaded interface and a flange interface. Flanges 3 with different numbers of through holes can be replaced, improving adaptability and facilitating maintenance and replacement. The rounded rubber ring 4 and the rubber sealing gasket 5 prevent the sealing gasket of the leak-proof interface from slipping off, which is beneficial for pipeline installation.
[0022] In this embodiment, annular grooves are provided on the front and rear surfaces of the rubber sealing gasket 5, which improves the sealing effect.
[0023] In this embodiment, the internally threaded sleeve 1 includes a connecting sleeve 101 and a threaded groove 102.
[0024] In this embodiment, the connecting sleeve 101 is fixedly installed on the rear surface of the flange 3, and the threaded groove 102 is formed on the inner side of the connecting sleeve 101 at the rear end.
[0025] In this embodiment, the externally threaded short pipe 2 includes an externally threaded connecting pipe 201, a first rubber sealing ring 202, and a second rubber sealing ring 203.
[0026] In this embodiment, the external threaded connecting pipe 201 is located inside the threaded groove 102, the first rubber sealing ring 202 is sleeved on the outside of the external threaded connecting pipe 201, and the second rubber sealing ring 203 is located inside the threaded groove 102 at the front end. The front surface of the external threaded connecting pipe 201 is in contact with the rear surface of the second rubber sealing ring 203, and the front surface of the first rubber sealing ring 202 is in contact with the rear surface of the connecting sleeve 101. The external threaded connecting pipe 201 can be rotated out of the connecting sleeve 101 through the threaded groove 102. The first rubber sealing ring 202 and the second rubber sealing ring 203 play a sealing role. The external threaded connecting pipe 201 is welded and fixed to the inlet and outlet of the carbon dioxide pump.
[0027] In this embodiment, both the No. 1 rubber sealing ring 202 and the No. 2 rubber sealing ring 203 have annular grooves on their outer sides. The short marking line on the outer side of the connecting sleeve 101 is aligned with the short marking line on the outer side of the external thread connecting tube 201. The annular grooves on the outer sides of the No. 1 rubber sealing ring 202 and the No. 2 rubber sealing ring 203 make them easy to deform and squeeze. The short marking lines on the outer sides of the connecting sleeve 101 and the external thread connecting tube 201 facilitate the alignment and installation of the external thread connecting tube 201 and the connecting sleeve 101.
[0028] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
