Description

Technical Field

[0001] The utility model belongs to the technical field of water meters, and particularly relates to a water meter with a sealing structure. Background Technique

[0002] A water meter is a device used to measure the water consumption of households or industries and is usually installed in the water supply pipeline. It can record the water flow used by users in real time and is generally divided into two types: mechanical water meters and electronic water meters. Mechanical water meters measure the water volume through the rotation of gears driven by water flow, while electronic water meters use sensors and digital technologies to provide higher measurement accuracy and more convenient reading. After long-term use, water meters are prone to problems of insufficient sealing. The main reason is that over time, the sealing rings and materials of the water meters may age due to environmental influences, temperature changes, etc., resulting in a decline in sealing performance and water leakage. The conventional countermeasure is to install waterproof devices around the water meters to reduce the impact of the environment on the water meters. Although this method can alleviate the water leakage of the water meters, the disadvantage is that the waterproof devices will increase the occupied area of the water meters and are not suitable for use in narrow spaces. At the same time, adding waterproof devices will increase the complexity and cost of maintenance. Therefore, a new structure is proposed to solve the above problems. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a water meter with a sealing structure.

[0004] The utility model is realized through the following technical solutions: A water meter with a sealing structure includes: a water meter main body, a reinforcing nut, and an internally threaded connecting pipe. The water meter main body is provided with a first connecting pipe on one side, the first connecting pipe is provided with a first externally threaded connecting pipe on one side, and the first externally threaded connecting pipe is provided with a second externally threaded connecting pipe on one side;

[0005] The internally threaded connecting pipe is provided on the left side of the second externally threaded connecting pipe, the second externally threaded connecting pipe is provided with a second connecting pipe on one side, the left side of the outer side of the first externally threaded connecting pipe is provided with a reinforcing nut, the inner side of the reinforcing nut is provided with a screwing hole, and a screwing groove is formed by the left depression of the annular area far from the center of the circle on the right side of the first externally threaded connecting pipe;

[0010] As a preferred embodiment, the inner side of the internally rotatable connecting pipe contacts the outer side of the sealing layer. The sealing layer is made of fluororubber and is in a ring-shaped cylindrical structure. During actual use, first rotate the reinforcing nut to the leftmost side of the externally rotatable connecting pipe, then align the left side of the internally rotatable connecting pipe with the right side of the rotatable connection groove, insert the left side of the internally rotatable connecting pipe into the rotatable connection groove, and then rotate the internally rotatable connecting pipe to rotatably connect the third thread and the first internal screw groove, thereby rotatably installing and fixing the internally rotatable connecting pipe and the rotatable connection groove. At this time, the inner side of the internally rotatable connecting pipe is in close contact with the outer side of the sealing layer. The sealing layer is made of fluororubber, so as to seal the connection between the internally rotatable connecting pipe and the rotatable connection groove. The embedded rotatable connection method of the internally rotatable connecting pipe and the rotatable connection groove increases the resistance of water flow overflow, further improving the sealing effect. The final effect is that through the rotatable connection of the internally rotatable connecting pipe and the rotatable connection groove and the close fit between the inner side of the internally rotatable connecting pipe and the outer side of the sealing layer, the sealing performance of the water meter main body is increased.

The reinforcing nut rotates and moves to the right until the right side of the reinforcing nut contacts the left side of the retaining ring. At this time, the rotation connection of the reinforcing nut is completed. The final effect is that the reinforcing nut increases the connection stability of the first externally rotatable connecting pipe and the second externally rotatable connecting pipe, thereby increasing the connection stability of the first docking pipe and the second docking pipe. The waterproof material applied to the surface of the second internal screw groove plays an auxiliary sealing effect, improving the sealing performance of the water meter main body and facilitating maintenance and use.

[0012] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: by setting the inner rotating tube, the rotating groove and the sealing layer, the inner rotating tube can be rotated and inserted into the rotating groove through the rotation connection of the thread three and the inner screw groove one, so that the inner side of the inner rotating tube is in close contact with the outer side of the sealing layer. On the one hand, the butt joint tube one and the butt joint tube two are connected and fixed, and on the other hand, the connection between the inner rotating tube and the rotating groove has good sealing performance, and the water meter body can be sealed and waterproofed without installing an external waterproof device, thereby reducing the occupied area of ​​the water meter body, facilitating disassembly and maintenance, and reducing maintenance costs. By setting the reinforcing nut, the outer rotating tube one and the outer rotating tube two, the butt joint of the outer rotating tube one and the outer rotating tube two can be reinforced, thereby increasing the stability of the connection between the butt joint tube one and the butt joint tube two, and at the same time achieving the effect of auxiliary sealing.

At this time, the inner side of the internally rotating connecting pipe 170 is in close contact with the outer side of the sealing layer 180. The sealing layer 180 is made of fluororubber, so as to seal the connection between the internally rotating connecting pipe 170 and the screwing groove 160.
