Description

Technical Field

[0001] The utility model relates to the technical field of elliptical gear flowmeters, in particular to a shock-absorbing elliptical gear flowmeter. Background Art

[0002] The oval gear flowmeter, a type of volumetric flowmeter, offers the highest precision among flowmeters. It utilizes a mechanical measuring element to continuously divide a fluid into individual known volumes. The total flow volume is measured based on the number of times the metering chamber is repeatedly filled and drained of that volume. Oval gear flowmeters can be manufactured from a variety of materials (cast iron, cast steel, 304 stainless steel, 316 stainless steel), and are suitable for flow measurement in industries such as the chemical, petroleum, pharmaceutical, electric power, metallurgy, and food. The flowmeter primarily consists of a housing, counter, oval gear, and couplings (magnetic and axial).

[0003] For example, a Chinese authorized patent, with the announcement number CN219511601U, discloses an anti-vibration device for an elliptical gear flowmeter, comprising an elliptical gear flowmeter body; connecting pipes provided at the left and right ends of the elliptical gear flowmeter body, and a shock-absorbing mechanism provided between the elliptical gear flowmeter body pipe and the connecting pipe. By providing a rubber ring at the connection between the pipe of the elliptical gear flowmeter body and the connecting pipe, the elasticity of the rubber ring and the shock-absorbing spring between the flange and the connecting flange are utilized to flexibly resist vibration at the connection between the pipe of the elliptical gear flowmeter body and the connecting pipe, effectively reducing the anti-vibration capacity of the overhead pipe in the vibration area and protecting the hard damage to the pipe caused by vibration; by providing bolts and nuts, the connection between the flange and the connecting flange is made tighter, and at the same time, the shock-absorbing spring provided between the flange and the connecting flange can effectively flexibly resist vibration at the connection between the pipe of the elliptical gear flowmeter body and the connecting pipe.

[0004] The above-mentioned traditional flow meter is generally provided with a counter. When the device is transported, the surface of the counter is easily squeezed and damaged. Once the counter is damaged, the device will be unable to read the value, which will cause the flow meter to malfunction and affect the service life of the device. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0028] Reference Figure 1-6 As shown, a shock-absorbing elliptical gear flowmeter includes a flowmeter body 1 and a counter 211 installed on the top of the flowmeter body 1, and also includes a cover 212 and a buffer pad 213 fixed to the bottom end of the cover 212. The buffer pad 213 can be made of rubber and can have a good buffering effect. When the flowmeter body 1 is transported, when the cover 212 is pressurized, the buffer pad 213 can buffer, thereby avoiding direct pressure on the top of the counter 211. The cover 212 can provide protection, thereby improving the service life of the equipment. The buffer pad 213 fits with the top of the counter 211, and the bottom end of the cover 212 is rotatably connected to the rotating plate 219 through a shock-absorbing mechanism. A fixed sleeve 220 is fixed to the outer wall of the counter 211. The outer wall of the fixed sleeve 220 is provided with a slot 221 for the rotating plate 219 to rotate horizontally for entering and exiting the interior of the fixed sleeve 220. The rotating plate 219 can be horizontally rotated to enter and exit the interior of the fixed sleeve 220, which is convenient for the staff to remove the cover 212. After the equipment is installed and used, the cover 212 can be easily disassembled, which is convenient for the cover 212 to be used multiple times for protection, thereby reducing the use cost of the equipment.

[0029] The shock absorbing mechanism includes a movable rod 214, a fixed cylinder 215, a shock absorbing spring 216 and a rotating ring 227. The movable rod 214 is fixed to the bottom end of the cover 212, and the top of the rotating plate 219 is rotatably connected to the rotating ring 227. The inner wall of the rotating ring 227 is fixed with a fixed cylinder 215 that is sleeved on the outer wall of the movable rod 214. The shock absorbing spring 216 is arranged inside the fixed cylinder 215 and one end is connected to the movable rod 214 and the other end is connected to the inner wall of the fixed cylinder 215. When the cover 212 is pressed downward, the movable rod 214 will be inserted into the fixed cylinder 215 and drive the shock absorbing spring 216 to compress, thereby converting the kinetic energy received into elastic potential energy, thereby achieving further shock absorption and enhancing the buffering effect of the pressure on the cover 212. A sliding chamber 217 is provided inside the fixed cylinder 215 , and a sliding plate 218 is fixed to the outer wall of the bottom end of the movable rod 214 , which slides with the sliding chamber 217 . The provision of the sliding chamber 217 and the sliding plate 218 can facilitate the movable rod 214 to slide along the inside of the fixed cylinder 215 .

[0030] A bracket 222 is fixed to the top of the fixed sleeve 220. A slot 224 is defined within the fixed sleeve 220 and the rotating plate 219. A rod 223 corresponding to the slot 224 is inserted through the bracket 222. By inserting the rod 223 through the bracket 222 and the slot 224, the rotating plate 219 and the fixed sleeve 220 are locked together, preventing the rotating plate 219 from separating from the fixed sleeve 220 during transportation. A top plate 225 is fixed to the top of the rod 223. The diameter of the top plate 225 is larger than that of the rod 223. The provision of the top plate 225 ensures that the rod 223 does not fall out of the slot 224, achieving a better protective effect. A return spring 226 is wrapped around the outer wall of the insertion rod 223. One end of the return spring 226 is connected to the top plate 225 and the other end is connected to the bracket 222. The return spring 226 can serve the purpose of rebound. In the initial state, the return spring 226 will drive the top plate 225 and the insertion rod 223 to move downward, and the insertion rod 223 can be stably inserted into the slot 224.

[0031] A first pipe 311 is fixedly mounted on the outer wall of the flowmeter body 1. The first pipe 311 can be connected to the outer wall of the flowmeter body 1 by welding. A first connecting plate 312 is fixed to the end of the first pipe 311 away from the flowmeter body 1. A second connecting plate 314 is connected to the outer wall of the first connecting plate 312 via a mounting mechanism. A second pipe 313 is fixed to the end of the second connecting plate 314 away from the first connecting plate 312. The mounting mechanism includes a locking bolt 315 and a locking nut 316. The locking bolt 315 passes through the interior of the first and second connecting plates 312 and 314. The locking nut 316 is threadedly connected to the outer wall of the locking bolt 315. The locking nut 316 is in contact with the outer wall of the first connecting plate 312. A staff member can rotate the locking bolt 315 and the locking nut 316 to install or remove the first and second connecting plates 312 and 314, which facilitates the staff member's maintenance of the flowmeter body 1.

[0032] Working principle: When the top of the counter 211 needs to be protected, the cover plate 212 is attached to the top of the counter 211. At this time, the buffer pad 213 can fit with the top of the counter 211. Then, the top plate 225 is pulled upward to drive the insertion rod 223 to move, and the reset spring 226 is driven to stretch. The rotating plate 219 is rotated to enter the interior of the fixed sleeve 220 through the slot 221. After the top plate 225 is released, the elasticity of the reset spring 226 can drive the insertion rod 223 to be pressed down and the insertion rod 223 is passed through the slot 224, which is used to prevent the rotating plate 219 from being separated from the interior of the fixed sleeve 220, thereby achieving the purpose of installing the cover plate 212.

[0033] During transportation, if the cover 212 is squeezed, the cover 212 drives the buffer pad 213 to be squeezed and compressed. The buffer pad 213 can buffer the kinetic energy received to prevent the top of the counter 211 from being subjected to force. At the same time, the downward pressure of the cover 212 will drive the movable rod 214 and the sliding plate 218 to move downward. The sliding plate 218 can slide along the inner wall of the sliding chamber 217 and drive the shock-absorbing spring 216 to be squeezed and compressed. The shock-absorbing spring 216 converts the kinetic energy received into elastic potential energy to achieve further shock absorption, thereby enhancing the stability of the cover 212 buffering and preventing the top of the counter 211 from being damaged by pressure.

[0034] When the flow meter body 1 needs to be installed, the first connecting plate 312 and the second connecting plate 314 are fitted together, and the locking bolt 315 is passed through the first connecting plate 312 and the second connecting plate 314. Then the locking nut 316 is rotated to make it threadedly connected to the locking bolt 315. The locking nut 316 can fit with the outer wall of the first connecting plate 312, and the locking bolt 315 will fit with the outer wall of the second connecting plate 314, thereby achieving the purpose of installing the first pipe 311 and the second pipe 313.
