Description

Technical Field

[0001] The utility model belongs to the technical field of water meters, and in particular relates to a water meter with a temperature monitoring function. Background Art

[0002] A water meter is an instrument that measures water flow, mostly the cumulative flow of water.

[0003] Currently, ultrasonic water meters are equipped with temperature probes to measure the temperature of the liquid flowing through them. If the probes are damaged, they need to be replaced, which requires the entire ultrasonic water meter to be disassembled, shutting down the flow of fluid in the pipeline and affecting production operations. Utility Model Content

[0004] The purpose of the present utility model is to solve the above-mentioned problems and to provide a water meter with a temperature monitoring function.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a water meter with temperature monitoring function, comprising:

[0006] The water meter body has two screw holes on opposite sides of its flange pipe;

[0007] a temperature sensor, which is screwed into one of the screw holes, wherein the instrument of the temperature sensor is located outside the flange pipe, and the original probe of the temperature sensor extends into the interior of the flange pipe;

[0008] a cylindrical tube, which is screwed into the other screw hole and extends into the interior of the flange tube;

[0009] A plug is located outside the flange pipe and is screwed onto the end of the cylindrical pipe.

[0010] As a further description of the above technical solution:

[0011] A blind hole is provided at the end of the cylindrical tube, an air avoidance groove is provided on the side wall of the cylindrical tube, the air avoidance groove is connected to the blind hole, a spare probe is provided in the blind hole, and the plug blocks the blind hole.

[0012] As a further description of the above technical solution:

[0013] The axis of the cylindrical tube coincides with the axis of the two screw holes, and the outer diameter of the original probe is not greater than the inner diameter of the cylindrical tube.

[0014] As a further description of the above technical solution:

[0015] A sinking hole is provided at the edge of the screw hole located at the temperature sensor, and the diameter of the sinking hole is the same as the diameter of the cylindrical tube.

[0016] As a further description of the above technical solution:

[0017] A sealing gasket is arranged in the sinking hole.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] 1. In the present invention, the original probe of the temperature sensor is extended into the flange pipe to measure the temperature, and the temperature is displayed on the meter. When the temperature sensor is damaged and needs to be repaired and maintained, it is only necessary to rotate the cylindrical tube to cover the original probe. The end of the cylindrical tube is against the inner wall of the flange pipe to isolate the temperature sensor from the inside of the flange pipe. At this time, the temperature sensor can be replaced without disassembling the water meter body or shutting down the flow of the pipeline fluid, and normal production operations will not be affected.

[0020] 2. In the present invention, when the original probe fails, the fluid flowing through the flange pipe enters the blind hole groove from the air avoidance groove, and the spare probe is in working condition, ensuring the normal use of the water meter. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the accompanying 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.

[0029] See also Figure 1-5 The present invention provides a technical solution: a water meter with temperature monitoring function, comprising:

[0030] The water meter body 1 has two screw holes 3 on opposite sides of its flange pipe 2;

[0031] A temperature sensor 4 is screwed into one of the screw holes 3 , wherein an instrument 41 of the temperature sensor 4 is located outside the flange pipe 2 , and an original probe 42 of the temperature sensor 4 extends into the interior of the flange pipe 2 ;

[0032] a cylindrical tube 5, which is screwed into the other screw hole 3 and extends into the interior of the flange tube 2;

[0033] a plug 6, which is located outside the flange pipe 2 and is screwed to the end of the cylindrical pipe 5;

[0034] A blind hole 7 is formed at the end of the cylindrical tube 5, and an air avoidance groove 8 is formed on the side wall of the cylindrical tube 5. The air avoidance groove 8 is connected to the blind hole 7. A spare probe 9 is provided in the blind hole 7. The plug 6 blocks the blind hole 7. When the original probe 42 fails, the fluid flowing through the flange tube 2 enters the blind hole 7 from the air avoidance groove 8. The spare probe 9 is in working condition, ensuring the normal use of the water meter.

[0035] The axis of the cylindrical tube 5 coincides with the axis of the two screw holes 3, and the outer diameter of the original probe 42 is not larger than the inner diameter of the cylindrical tube 5, ensuring that the cylindrical tube 5 can be smoothly inserted into the original probe 42;

[0036] A sinking hole 10 is provided at the edge of the screw hole 3 located at the temperature sensor 4. The diameter of the sinking hole 10 is the same as that of the cylindrical tube 5. The cylindrical tube 5 extends into the sinking hole 10, isolating the temperature sensor 4 from the interior of the flange tube 2. At this time, the temperature sensor 4 can be replaced.

[0037] A sealing gasket 11 is provided in the sinking hole 10 to ensure the sealing of the structure.

[0038] Working principle: First, the original probe 42 of the temperature sensor 4 extends into the flange tube 2 to measure the temperature, and the temperature is displayed on the instrument 41. Secondly, when the temperature sensor 4 is damaged and needs to be repaired and maintained, you only need to rotate the cylindrical tube 5 to put it on the original probe 42, and the end of the cylindrical tube 5 will be against the inner wall of the flange tube 2, that is, the end of the cylindrical tube 5 is stuck in the sinking hole 10 and against the sealing gasket 11, isolating the temperature sensor 4 from the interior of the flange tube 2. At this time, the temperature sensor 4 can be replaced without disassembling the water meter body 1 or shutting down the circulation of the pipeline fluid, and normal production operations are not affected. Finally, when repairing and maintaining the temperature sensor 4, the fluid flowing through the flange tube 2 enters the blind hole 7 from the air avoidance groove 8, and the spare probe 9 is in working condition to ensure normal temperature measurement and use of the water meter.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
