Description

Technical Field

[0001] The utility model belongs to the technical field of venturi tubes, in particular to a venturi tube with a noise reduction structure. Background Art

[0002] The Venturi tube is a vacuum device that uses fluid to transfer energy and mass. It is widely used in industry, such as measuring the volume flow rate of a single-phase stable fluid (liquid, gas or steam) in a closed pipeline. The Venturi tube has the characteristics of simple structure and reliable operation, and does not require actual flow verification, with small pressure loss and high measurement accuracy.

[0003] At present, there are some Venturi tube structures on the market, such as a Venturi tube disclosed on the Chinese Patent Network, with the announcement number CN208547387U. This Venturi tube has the advantages of preventing rainwater or water vapor from entering the interior of the Venturi tube, protecting the internal structure of the Venturi tube from corrosion, and extending the service life of the Venturi tube. However, there are some defects and deficiencies that need to be improved: (1) When the Venturi tube is working, due to the turbulence, eddy current and pressure change of the fluid passing through the pipeline, a certain amount of noise will be generated, and some existing Venturi tubes lack corresponding noise reduction measures, which makes it difficult to effectively reduce the working noise of the Venturi tube, thereby affecting the surrounding working environment; (2) Some existing Venturi tubes lack reinforcement of the supporting structure. When the supporting structure is loose, the Venturi tube will vibrate when working, which will not only generate vibration noise, but also cause collision and wear of the Venturi tube due to vibration, thereby affecting the service life of the Venturi tube. Therefore, in view of the above problems, the Venturi tube with a noise reduction structure provided by the utility model is of great significance. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In the description of the present invention, it should be understood that terms such as "relative", "one end", "inside", "lateral", "end", "two ends", "both sides", "front", "one end face", "the other end face" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0032] See also Figure 1-9 As shown, a venturi tube with a noise reduction structure of the utility model comprises a tube body, the tube body comprises a throat 1, a contraction section 2 and a diffusion section 3, the bottoms of the contraction section 2 and the diffusion section 3 are fixedly connected with a support seat 4, and the tube body can be supported by the support seat 4, the cross section of the support seat 4 is rectangular, a plurality of positioning grooves 5 are provided at the bottom thereof, and a base 6 is provided at the bottom of the support seat 4, the front of the base 6 is U-shaped, a plurality of positioning rods 7 are fixedly connected at both sides of the top thereof, and a noise reduction cover 8 is installed at the top of the base 6, threaded holes 9 are provided at the side walls at both ends of the base 6, and reinforcement components are installed at both ends of the base 6;

[0033] The reinforcement assembly includes a threaded rod 10, which is threadedly connected in the threaded hole 9. One end of the threaded rod 10 is fixedly connected to a fixing ring 11, and the other end of the threaded rod 10 is provided with a reinforcement plate 12. A pair of springs 13 are fixedly connected between the reinforcement plate 12 and the inner wall of the base 6. The pair of springs 13 are symmetrically distributed about the threaded hole 9. The threaded rod 10 can be driven to move along the threaded hole 9 by rotating the fixing ring 11. When the end of the threaded rod 10 contacts the reinforcement plate 12, the reinforcement plate 12 can be driven to move toward the support seat 4 until the reinforcement plate 12 is tightly against the side wall of the support seat 4. At this time, the support seat 4 can be reinforced by clamping the reinforcement plate 12 to improve the support stability of the support seat 4, thereby effectively avoiding the vibration of the venturi tube during operation due to the loosening of the support seat 4.

[0034] Among them, the side of the noise reduction cover 8 is N-shaped, and a number of sound-absorbing strips 14 are arranged on the inner wall surfaces on both sides. The sound-absorbing strips 14 are long strips and are equidistantly linearly distributed along the height direction of the noise reduction cover 8. The sound-absorbing strips 14 are made of sound-absorbing cotton and other materials, and are fixed by glue or other means. When the noise reduction cover 8 is installed on the base 6, it can cover the outside of the entire pipe body. At this time, each sound-absorbing strip 14 can effectively absorb the noise generated by the venturi tube when it is working, thereby playing a role in noise reduction.

[0035] Among them, a number of sound-blocking blocks 15 are fixedly connected to the top inner wall of the noise reduction cover 8. The sound-blocking blocks 15 are in the shape of long strips with a triangular cross-section. The sound-blocking blocks 15 are arranged in an equidistant annular array along the top curved surface of the noise reduction cover 8. When the noise reduction cover 8 is covered on the outside of the pipe body, the propagation and diffusion of noise can be effectively blocked and disrupted by each sound-blocking block 15, thereby further improving the noise reduction effect of the noise reduction cover 8.

[0036] Among them, the bottoms of both sides of the noise reduction cover 8 are L-shaped and have a plurality of mounting holes 16. A plurality of mounting posts 17 are fixedly connected to the top of the base 6. The number of mounting posts 17 and the mounting holes 16 are the same, the diameters are equal, and the center of each mounting post 17 corresponds one-to-one to the center of each mounting hole 16. When the noise reduction cover 8 is placed on the base 6, each mounting post 17 can be aligned with and pass through the corresponding mounting holes 16. At this time, the noise reduction cover 8 can be positioned and fixed by the mutual cooperation of the mounting posts 17 and the mounting holes 16, so as to firmly fix the noise reduction cover 8 on the base 6, thereby avoiding loosening and displacement of the noise reduction cover 8 after installation, and also facilitating the disassembly of the noise reduction cover 8 at any time.

[0037] Among them, the number of positioning rods 7 and positioning grooves 5 are the same, the diameters are equal, and the center of each positioning rod 7 corresponds to the center of each positioning groove 5 one by one. When the support seat 4 is placed on the base 6, each positioning rod 7 can be aligned and inserted into the corresponding positioning groove 5. At this time, the support seat 4 can be positioned and fixed through the mutual cooperation of the positioning rod 7 and the positioning groove 5, so that the support seat 4 together with the tube body can be firmly fixed on the base 6. A buffer block 18 is provided on the top surface of each positioning rod 7. The buffer block 18 is made of elastic material such as rubber and is fixed by glue or the like. When the positioning rod 7 is inserted into the positioning groove 5, the buffer block 18 can play a role of buffering protection to avoid direct contact between the surface of the positioning rod 7 and the positioning groove 5 to cause collision and wear.

[0038] Among them, the cross-section of the reinforcement plate 12 is C-shaped, and the width of its inner wall is equal to the width of the support seat 4, and a layer of buffer pad 19 is provided on the inner wall surface of the reinforcement plate 12. The buffer pad 19 is made of elastic materials such as sponge and is fixed by glue or other means. When the reinforcement plate 12 is attached to the side wall of the support seat 4, the buffer pad 19 can play a buffering and protective role to avoid direct contact between the surface of the support seat 4 and the reinforcement plate 12 to cause collision and wear.

[0039] Among them, a plurality of anti-skid pads 20 are arranged on the bottom surface of the base 6. The anti-skid pads 20 are long strips, and a herringbone anti-skid pattern is engraved on the surface thereof. The anti-skid pads 20 are evenly spaced linearly distributed along the length direction of the base 6. The anti-skid pads 20 are made of elastic materials such as rubber and are fixed by glue or the like. When the base 6 is placed on a contact surface such as the ground, the anti-skid patterns on the surface of each anti-skid pad 20 can increase the friction between the base 6 and the contact surface to play an anti-skid role, thereby effectively preventing the base 6 from slipping and displacing and affecting the normal operation of the tube body.

[0040] The circuits, electronic components and chip modules involved in the utility model are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to software and methods.

[0041] The standard parts used in the application documents can all be purchased from the market. All the components in this application document can be customized according to the description in the specification and drawings. The specific connection methods of each part adopt mature conventional means such as bolts, rivets, welding, etc. in the prior art. Machinery, parts and equipment all adopt conventional models in the prior art. The electrical components appearing in this article are all electrically connected to the external main controller and 220V AC power, and the main controller can be a conventional known device that controls the LED lamp body, etc.

[0042] The working principle of the utility model is:

[0043] When the utility model is in use, the tube body can be placed on the base 6. When placing, the positioning rods 7 on the top of the base 6 are aligned and inserted into the corresponding positioning grooves 5 at the bottom of the support base 4, so that the support base 4 together with the tube body can be firmly fixed on the base 6. Then, the fixing ring 11 is rotated to drive the threaded rod 10 to move along the threaded hole 9. When the end of the threaded rod 10 contacts the reinforcing plate 12, the reinforcing plate 12 can be driven to move toward the direction of the support base 4 until the reinforcing plate 12 is tightly against the side wall of the support base 4. At this time, the support base 4 can be clamped by the reinforcing plate 12. Reinforcement is carried out to improve the supporting stability of the support base 4, thereby effectively avoiding the vibration of the venturi tube during operation due to the loosening of the support base 4. A noise reduction cover 8 is installed on the base 6, and the noise reduction cover 8 can cover the outside of the entire tube body. The various sound-absorbing strips 14 on the inner walls on both sides of the noise reduction cover 8 can effectively absorb the noise generated by the venturi tube during operation, thereby playing a role in noise reduction. At the same time, the various sound-blocking blocks 15 on the top inner wall of the noise reduction cover 8 can effectively hinder and disrupt the propagation and diffusion of noise, thereby further improving the noise reduction effect of the noise reduction cover 8.
