Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically to a pipeline connection sealing structure and a dry flow meter. Background Technology

[0002] A patent document with publication number CN204664654U discloses a pipeline sealing connection structure, belonging to the field of sealing device technology. Designed to solve the problem of existing sealing rings being prone to deformation under high pressure, the pipeline sealing connection structure includes a sealing ring, a first pipeline and a second pipeline respectively connected to the sealing ring. The sealing ring includes a sealing ring body with a cavity, an elastic element sleeved within the sealing ring body, and a base connected to one end face of the elastic element. The first pipeline is pressed against the other end face of the elastic element, and the second pipeline passes through the base and connects to the first pipeline. A circular hole is opened in the center of the base for inserting the second pipeline, and the second pipeline and the base are connected by an interference fit. This pipeline sealing connection structure can solve the problems of existing connection structures such as easy deformation of the sealing ring, weak connection, and poor sealing effect under high pressure.

[0003] However, with the above-mentioned solutions and existing technologies, when the dry flow meter is connected to the pipeline, a pipeline sealing structure needs to be set at its inlet and outlet. When the dry flow meter malfunctions during use or needs to be maintained or calibrated regularly, some existing sealing structures are fixed connections and lack a mechanism for easy disassembly and installation. These issues can be improved and optimized.

[0004] Therefore, this utility model proposes a pipeline connection sealing structure to solve the above problems. Utility Model Content

[0014] A pipeline connection sealing structure and a dry flow meter, including the aforementioned pipeline connection sealing structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the combined structure of the fixing plate, snap-fit ​​assembly, fixing assembly, sealing assembly and telescopic assembly, when maintaining, calibrating or troubleshooting the dry flow meter, the maintenance personnel can loosen the screws connecting the snap-fit ​​end and the snap-fit ​​groove and rotate the fixing ring to separate the silicone tube from the flow meter connection, shortening downtime, improving maintenance efficiency, and avoiding equipment damage. The first sealing gasket of the sealing assembly is inside the snap-fit ​​ring and the second sealing gasket is inside the fixing ring.

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, not all embodiments, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0022] Example 1: Please refer to Figures 1 to 2 A pipeline connection sealing structure and a dry flow meter, comprising a fixed plate 1, a snap-fit ​​assembly 2, a fixing assembly 3, a sealing assembly 4, and a telescopic assembly 5; the snap-fit ​​assembly 2 is fixed to one end of the fixed plate 1, and the snap-fit ​​assembly 2 is fixedly snapped onto the silicone tube 6; the fixing assembly 3 is connected to the snap-fit ​​assembly 2, and the sealing assembly 4 is disposed inside the snap-fit ​​assembly 2 and the fixing assembly 3.

[0023] The silicone tube 6 is appropriately connected to the air outlet 7, which is located at one end of the flow meter 8. The flow meter 8 has an air inlet 9 at its end, a touch screen 10 on its top, and an observation window 11 on its front.

[0024] In use, first, attach the silicone tube 6 to the outlet 7 of the flow meter 8, so that the snap ring 201 of the snap assembly 2 surrounds the silicone tube 6, and use the fixing protrusion 202 to fix the snap ring 201 to the fixing plate 1. Then, rotate one end of the fixing ring 301 of the fixing assembly 3 to the snap ring 201 through the connecting shaft 203, so that the snap end 302 of the fixing ring 301 snaps into the snap groove 204 of the snap ring 201, and fixes it with screw thread connection, thereby achieving the initial fixation of the connection between the silicone tube 6 and the outlet 7.

[0025] Example 2: Based on Example 1, please refer to... Figures 2 to 3The buckle ring 201 in the buckle assembly 2 is provided with a fixing protrusion 202 at its end. The fixing protrusion 202 is fixed on the fixing plate 1. A connecting shaft 203 is provided on one side of the buckle ring 201, and a snap-fit ​​groove 204 is provided on the other side of the buckle ring 201.

[0026] One end of the fixing ring 301 in the fixing component 3 is adapted to be rotatably connected to the connecting shaft 203. A snap-fit ​​end 302 is fixedly provided on one end of the fixing ring 301. The snap-fit ​​end 302 is adapted to be snapped into the snap-fit ​​groove 204. The snap-fit ​​end 302 and the snap-fit ​​groove 204 are fixed by screw thread connection.

[0027] When using the flow meter 8, if maintenance or repair is required, the maintenance personnel should first loosen the screw connecting the snap-fit ​​end 302 and the snap-fit ​​groove 204, and then rotate around the connecting shaft 203 to open the fixing ring 301, which will release the fixation of the silicone tube 6 and make it easy to remove the silicone tube 6 from the air outlet 7. The operation is convenient and efficient.

[0028] Example 3: Based on Example 2, please refer to... Figures 3 to 4 In the sealing assembly 4, the first sealing gasket 401 is fixedly disposed inside the snap ring 201, and the second sealing gasket 402 is tightly attached to the outside of the first sealing gasket 401. The second sealing gasket 402 is fixed inside the fixing ring 301.

[0029] The telescopic assembly 5 has a first connecting plate 502 fixedly installed at the end of the telescopic cylinder 501. A sleeve 503 is adapted to be connected to the outside of the telescopic cylinder 501. A second connecting plate 504 is fixedly installed on the sleeve 503. A spring 505 is fixed on the first connecting plate 502 and the second connecting plate 504. The spring 505 is sleeved on the outside of the sleeve 503.

[0030] During use, in normal operation, the first sealing gasket 401 and the second sealing gasket 402 of the sealing assembly 4 fit tightly together, which can effectively prevent gas or liquid from leaking at the connection between the silicone tube 6 and the outlet 7. It can maintain a good sealing effect in both high-pressure and low-pressure conditions, ensuring the accuracy of the flow meter 8. When the pipeline is subjected to external impact or vibration caused by fluid pressure fluctuations, the spring 505 between the telescopic cylinder 501 and the sleeve 503 of the telescopic assembly 5 plays a role. The force is transmitted through the first connecting plate 502 and the second connecting plate 504. The spring 505 extends and retracts to absorb and disperse energy, avoiding the impact force from acting directly on the sealing structure and the flow meter 8.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
