Description

Technical Field

[0001] The utility model relates to the technical field of Venturi valves, in particular to a quick installation structure applied to Venturi valves. Background Art

[0002] The Venturi valve is a valve manufactured using the principle of the Venturi effect. It is a Venturi airflow control valve that can expand airflow control to the highest level. Its aerodynamic design allows for silent operation.

[0003] Among the existing Venturi valve structures, most are one-piece structures, and the one-piece Venturi valve has a high degree of structural integration. Once a failure occurs or maintenance is required, the entire valve body needs to be disassembled, and the maintenance process is relatively difficult. During installation, it is necessary to consider the connection and coordination between the various components of the valve body. Due to the limitation of the installation space, the installation process is relatively cumbersome and cannot be installed quickly. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a quick installation structure for a Venturi valve.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A quick installation structure for a Venturi valve, comprising an upper valve body and a lower valve body, the upper valve body and the lower valve body being connected to each other by a positioning column, a movable ring being sleeved on the outer surface of the upper valve body, a protrusion being fixedly connected to the inner wall of the movable ring, a traction rope being connected to one side of the protrusion, a sliding groove being provided on the inner wall of the upper valve body, a guide ball being provided in the sliding groove, one end of the traction rope extending into the sliding groove and being fixedly connected to the guide ball, a limiting plate being fixedly connected to the outer wall of the upper valve body, and a compression spring being provided between the limiting plate and the movable ring.

[0007] Preferably, a butt joint is provided at the middle portion of the upper valve body, a mounting collar is fixedly connected to the top outer wall of the butt joint, and the butt joint is communicated with the mounting collar.

[0008] Preferably, a limiting groove is provided on the outer wall of the butt joint pipe.

[0009] Preferably, a rubber gasket is provided between the movable ring and the mounting collar, and a valve stem is provided at the inner bottom of the upper valve body.

[0010] Preferably, a positioning hole cooperating with the positioning column is formed at one end of the lower valve body close to the upper valve body.

[0011] The beneficial effects of the utility model are:

[0012] By dividing the Venturi valve into multiple modular parts including the upper valve body, the lower valve body and the butt joint, the individual modules of the Venturi valve can be disassembled and replaced or repaired separately as needed, without having to replace the entire Venturi valve, thus reducing maintenance costs. The butt joint and the upper valve body can be quickly connected and fixed through the cooperation of the movable ring, the bump and the guide ball, making the installation and removal process faster and more convenient.

[0013] The elasticity of the rubber gasket can fill the gaps between the connection parts of the movable ring, the mounting collar and the upper valve body under the action of external force, forming an effective seal to prevent erosion by external media. Since the rubber gasket is a prefabricated sealing material, it can be directly inserted into its connection part without the need for additional sealant or glue, thereby simplifying the installation process and improving installation efficiency.

[0022] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0023] Example:

[0024] Reference Figure 1-4 A quick installation structure for a Venturi valve includes an upper valve body 1 and a lower valve body 2. The upper valve body 1 and the lower valve body 2 are connected to each other by a positioning column 3. A movable ring 4 is sleeved on the outside of the upper valve body 1. A protrusion 14 is fixedly connected to the inner wall of the movable ring 4. A traction rope 5 is connected to one side of the protrusion 14. A sliding groove is opened on the inner wall of the upper valve body 1. A guide ball 6 is arranged in the sliding groove. One end of the traction rope 5 extends into the sliding groove and is fixedly connected to the guide ball 6. The outer wall of the upper valve body 1 is fixedly connected to a limit plate 7. A compression spring 8 is arranged between the limit plate 7 and the movable ring 4.

[0025] A butt joint pipe 9 is provided at the middle of the upper valve body 1 , and a mounting collar 10 is fixedly connected to the top outer wall of the butt joint pipe 9 , and the butt joint pipe 9 is in communication with the mounting collar 10 .

[0026] A limiting groove 11 is provided on the outer wall of the butt joint 9 .

[0027] A rubber gasket 12 is provided between the movable ring 4 and the mounting collar 10 , and a valve stem 13 is provided at the inner bottom of the upper valve body 1 .

[0028] A positioning hole that matches the positioning column 3 is formed at one end of the lower valve body 2 close to the upper valve body 1 .

[0029] In this embodiment, when the Venturi valve needs to be installed on the connecting pipe, first insert the positioning column 3 at the bottom of the upper valve body 1 into the positioning hole on the lower valve body 2 to complete the connection between the upper valve body 1 and the lower valve body 2, then dial the moving ring 4 downward, and the compression spring 8 is squeezed when the moving ring 4 moves downward, and then the docking pipe 9 is vertically inserted into the interior of the upper valve body 1. When the docking pipe 9 is inserted into the interior of the upper valve body 1 and moves downward to a suitable position, during the downward movement of the docking pipe 9, its bottom squeezes the guide ball 6 to both sides, so that the guide ball 6 slides to the connection between the moving ring 4 and the top of the protrusion 14. When the mounting collar 10 at the top of the docking pipe 9 is embedded in the top of the upper valve body 1, the moving ring 4 is then dialed upward, and the protrusion 14 is driven to move upward when the moving ring 4 moves upward. When the butt joint 9 needs to be disassembled and repaired, the movable ring 4 only needs to be moved down again so that the traction rope 5 pulls the guide ball 6 so that the guide ball 6 is out of the limit groove 11 of the butt joint 9, and the butt joint 9 and the upper valve body 1 are fixed to complete the installation and fixation between the butt joint 9 and the upper valve body 1. Then the top of the butt joint 9 can be installed and connected to the connecting pipe, which simplifies the installation process. At the same time, the rubber gasket 12 forms a sealing layer between the movable ring 4, the mounting collar 10 and the upper valve body 1 to ensure that the connection parts are well sealed, so that no excessive torque is required, making the installation faster. When the butt joint 9 needs to be disassembled and repaired, it is only necessary to move the movable ring 4 down again so that the traction rope 5 pulls the guide ball 6 so that the guide ball 6 is out of the limit groove 11, making installation and disassembly faster and more convenient.
