Description

Technical Field

[0001] This utility model relates to the field of pipeline connection and control equipment technology, and in particular to a quick-connect valve. Background Technology

[0002] In pipeline systems of industries such as chemical, food, pharmaceutical, and water treatment, valves are key components for controlling the flow of media. Their ease of installation and maintenance, connection sealing, and long-term stability directly affect the overall operating efficiency and safety of the pipeline system.

[0003] However, in existing technologies, traditional valves are mostly connected to pipelines using welding, flange bolts, or thermofusion. Welding connections require specialized equipment and technicians, and subsequent valve replacement due to damage necessitates cutting the pipeline, causing irreversible damage to the system. Flange bolt connections require tightening multiple bolts individually, making installation and disassembly time-consuming and labor-intensive, especially in confined spaces. Thermofusion connections are only suitable for pipelines of specific materials and cannot be disassembled after connection, resulting in poor flexibility. Meanwhile, while some quick-install valves simplify installation, they suffer from low connection positioning accuracy, loosening and leakage due to vibration or media pressure fluctuations, and potential seal failure due to displacement of the connection points after long-term use. These issues make it difficult to meet the demands of high-precision, high-sealing, and easy-to-maintain pipeline systems. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of inconvenient installation and disassembly of traditional valves, limited application scope, and low positioning accuracy, poor sealing and stability of some quick-installation valves in the existing technology, and to propose a quick-installation valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-connect valve, comprising a first connecting pipe, a connecting chamber, and a second connecting pipe, wherein the first connecting pipe is connected to the second connecting pipe, the connecting chamber is fixedly installed at the junction of the first connecting pipe and the second connecting pipe, the top of the connecting chamber is connected to a receiving chamber, one end of the second connecting pipe is fixedly connected to a quick-connect mechanism, the quick-connect mechanism comprising a third connecting pipe, a first limiting ring, and a second limiting ring, wherein an extension block is fixedly installed at the end of the first limiting ring and the end of the second limiting ring, a connecting rod is threaded on the inner side of one of the extension blocks, and protrusions are fixedly installed on both sides of the end of the connecting rod, the protrusions being rotatably connected to the second limiting ring, and limiting protrusions are fixedly installed at the edges of the ends of the second and third connecting pipes, wherein the first and second limiting rings are both sleeved on the edges of the limiting protrusions.

[0006] Preferably, cavities are provided on the inner side of the first limiting ring and the inner side of the second limiting ring, and the shape of the cavity is adapted to the limiting protrusion.

[0007] Preferably, a sealing ring is fitted on one side of the limiting protrusion, and the sealing ring is located inside the cavity.

[0008] Preferably, a limiting rod is rotatably mounted inside another of the extension blocks, and the end of the limiting rod is provided with a threaded groove.

[0009] Preferably, the end of the limiting rod is threadedly connected to a limiting end, and the end of the limiting rod is located inside the end extension block of the second limiting ring.

[0010] Preferably, the end of the limiting rod abuts against the surface of the extension block.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, a quick-installation mechanism consisting of a third connecting pipe, a first limiting ring, a second limiting ring, a connecting rod, a protrusion, and an extension block is provided. With the limiting protrusions at the ends of the second and third connecting pipes, and the cavities on the inner sides of the first and second limiting rings that adapt to the limiting protrusions, a quick connection can be completed without welding, hot melting, or multiple bolts. This greatly simplifies the installation and disassembly process, reduces the difficulty of operation and labor costs, and is compatible with various industry pipeline systems. It solves the problems of cumbersome installation of traditional valves, damage to pipelines during disassembly, and low positioning accuracy of some quick-installation valves.

[0013] 2. In this utility model, by embedding a sealing ring on one side of the limiting protrusion and positioning the sealing ring inside the cavity during connection, the clamping force of the limiting ring ensures that the sealing ring tightly fits the two limiting protrusions, enhancing the connection sealing performance. Simultaneously, a limiting rod and a limiting end are added. After the connecting rod is initially clamped, the limiting rod is rotated to engage with the extension block, and the limiting end is used to lock the position, further reinforcing the clamping state of the first and second limiting rings. This effectively prevents loosening and displacement of the connection due to vibration and medium pressure fluctuations during long-term use, solving the problems of easy sealing failure and poor long-term stability of existing quick-installation valves, and ensuring the safe and reliable operation of the pipeline system.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a quick-connect valve, including a first connecting pipe 1, a connecting chamber 2, and a second connecting pipe 3. The first connecting pipe 1 and the second connecting pipe 3 are connected. The connecting chamber 2 is fixedly installed at the junction of the first connecting pipe 1 and the second connecting pipe 3. The top of the connecting chamber 2 is connected to a receiving chamber 4. One end of the second connecting pipe 3 is fixedly connected to a quick-connect mechanism 5. The quick-connect mechanism 5 includes a third connecting pipe 51, a first limiting ring 52, and a second limiting ring 53. An extension block 56 is fixedly installed at the end of the first limiting ring 52 and the end of the second limiting ring 53. One of the extension blocks 56 has an inner... A connecting rod 54 is installed on the side thread. Protrusions 55 are fixedly installed on both sides of the end of the connecting rod 54. The protrusions 55 are rotatably connected to the second limiting ring 53. Limiting protrusions 59 are fixedly installed at the edge of the end of the second docking pipe 3 and the edge of the end of the third docking pipe 51. The first limiting ring 52 and the second limiting ring 53 are both sleeved on the edge of the limiting protrusions 59. A cavity 511 is opened on the inner side of the first limiting ring 52 and the inner side of the second limiting ring 53. The shape of the cavity 511 is adapted to the limiting protrusion 59. A sealing ring 510 is fitted on one side of the limiting protrusion 59. The sealing ring 510 is located inside the cavity 511.

[0021] The specific setup and function of this embodiment are described below. First, the limiting protrusion 59 at the end of the second connecting pipe 3 is aligned with the limiting protrusion 59 at the end of the third connecting pipe 51, so that the sealing ring 510 fitted on one side of the limiting protrusion 59 is between the two limiting protrusions 59. Then, the first limiting ring 52 and the second limiting ring 53 are respectively fitted onto the edges of the two aligned limiting protrusions 59. At this time, the limiting protrusions 59 are embedded inside the first limiting ring 52 and the second limiting ring 53. Within the cavity 511, whose shape matches the limiting protrusion 59, the sealing ring 510 is simultaneously located inside the cavity 511. The second limiting ring 53 is directly rotated to approach the first limiting ring 52, thereby clamping the two limiting protrusions 59. The protrusions 55 on both sides of the connecting rod 54 determine the rotation center of the second limiting ring 53, thus achieving a rapid connection between the second connecting pipe 3 and the third connecting pipe 51. The medium can flow in from the first connecting pipe 1 and be fixed at the junction of the first connecting pipe 1 and the second connecting pipe 3. The medium enters the second docking pipe 3 through the connecting chamber 2 and then flows out through the third docking pipe 51 connected to the second docking pipe 3, completing the medium transportation. When disassembling, rotating the connecting rod 54 in the opposite direction can loosen the first limiting ring 52 and the second limiting ring 53, separating the two docking pipes. The receiving chamber 4 is used to accommodate the sealing block. The quick-installation mechanism 5, composed of the first limiting ring 52, the second limiting ring 53, the connecting rod 54, the protrusion 55, and the extension block 56, works in conjunction with the limiting protrusion 59 at the ends of the second docking pipe 3 and the third docking pipe 51 and the cavity 511. The connection and disassembly of the second docking pipe 3 and the third docking pipe 51 can be quickly completed without complicated tools, greatly improving the installation and disassembly efficiency. The matching design of the limiting protrusion 59 and the cavity 511 can accurately position the two docking pipes and avoid connection misalignment. At the same time, the sealing ring 510, which is embedded on one side of the limiting protrusion 59 and located inside the cavity 511, can enhance the sealing performance of the second docking pipe 3 and the third docking pipe 51 after connection and prevent medium leakage.

[0022] Example 2: Figure 2 and Figure 3 As shown, a limiting rod 57 is rotatably mounted inside another extension block 56. The end of the limiting rod 57 is provided with a threaded groove. The end of the limiting rod 57 is threadedly connected to a limiting end head 58. The end of the limiting rod 57 is located inside the extension block 56 at the end of the second limiting ring 53. The end of the limiting end head 58 abuts against the surface of the extension block 56.

[0023] The overall effect of this embodiment is that after the first limiting ring 52 and the second limiting ring 53 clamp the limiting protrusion 59 through the connecting rod 54, the limiting rod 57 installed inside another extension block 56 is rotated, causing the end of the limiting rod 57 to move toward the inner side of the extension block 56 at the end of the second limiting ring 53. Because the end of the limiting rod 57 has a threaded groove, after it moves to abut against the surface of the extension block 56, the limiting end 58 is threaded into the threaded groove of the limiting rod 57. Through the threaded engagement between the limiting end 58 and the limiting rod 57, the position of the limiting rod 57 is further locked, so that the limiting end 58 continuously abuts against the extension block 56. The limiting rod 57, the limiting end 58, and other components such as the original extension block 56 and connecting rod 54 work together to further strengthen the connection after the quick-installation mechanism 5 is initially clamped, preventing the first limiting ring 52 and the second limiting ring 53 from shifting due to the loosening of the connecting rod 54 during long-term use. The end of the limiting rod 57 abuts against the surface of the extension block 56, and combined with the threaded locking of the limiting end 58, it can enhance the clamping stability of the first limiting ring 52 and the second limiting ring 53, thereby improving the firmness of the connection between the second docking pipe 3 and the third docking pipe 51 and reducing the risk of medium leakage caused by loose connection; at the same time, it does not affect the original quick-installation operation convenience.

[0024] The usage method and working principle of this device are as follows: First, align the limiting protrusion 59 fixed at the end edge of the second connecting pipe 3 with the limiting protrusion 59 fixed at the end edge of the third connecting pipe 51, so that the sealing ring 510 fitted on one side of the limiting protrusion 59 is between the two limiting protrusions 59. Then, put the first limiting ring 52 and the second limiting ring 53 in the quick-release mechanism 5 onto the edges of the two aligned limiting protrusions 59 respectively. At this time, the limiting protrusion 59 is embedded in the inner side of the first limiting ring 52 and the inner side of the second limiting ring 53, and the shape is... Within the cavity 511 that matches the limiting protrusion 59, the sealing ring 510 is simultaneously located inside the cavity 511. Then, the second limiting ring 53 is directly rotated to approach the first limiting ring 52, clamping the two limiting protrusions 59. During this process, the protrusions 55 fixed on both sides of the end of the connecting rod 54 determine the rotation center of the second limiting ring 53, thereby achieving a rapid connection between the second connecting pipe 3 and the third connecting pipe 51. After the first limiting ring 52 and the second limiting ring 53 clamp the limiting protrusions 59 via the connecting rod 54, they are rotatably installed on another extension... The limiting rod 57 inside the extension block 56 moves its end toward the inner side of the extension block 56 at the end of the second limiting ring 53. After it moves to abut against the surface of the extension block 56, the limiting end 58 is threaded into the threaded groove at the end of the limiting rod 57. The threaded engagement between the limiting end 58 and the limiting rod 57 locks the position of the limiting rod 57, ensuring that the limiting end 58 continuously abuts against the extension block 56. After the connection is completed, the medium flows in from the first docking pipe 1 and passes through the junction of the first docking pipe 1 and the second docking pipe 3. The medium enters the second docking pipe 3 through the connecting chamber 2 and then flows out through the third docking pipe 51 connected to the second docking pipe 3 to realize the medium transportation. When disassembly is required, if there is an installation limit end 58, rotate it in the opposite direction to remove the limit end 58. Then rotate the limit rod 57 in the opposite direction to disengage it from the top connection of the extension block 56. Then rotate the connecting rod 54 in the opposite direction to loosen the first limit ring 52 and the second limit ring 53. Finally, remove the first limit ring 52 and the second limit ring 53 to separate the second docking pipe 3 from the third docking pipe 51.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
