Description

Technical Field

[0001] The utility model belongs to the technical field of flow meters, and in particular relates to a novel flow meter structure. Background Art

[0002] A flow meter is an instrument used to measure the flow rate of a fluid (gas or liquid) through a specific pipe section. Flow meters play a vital role in many fields such as industry, environmental monitoring, and scientific research experiments.

[0003] At present, when the injection molding machine produces the rotor of the existing flow meter, the magnet on the middle rotor is embedded in a rectangular shape. This requires placing the magnet during injection molding and then injecting the rotor out of the mold. In addition, the sealing ring between the two shells is rectangular, which leads to slow rotor production efficiency. Employees need to place the magnet next to the injection molding machine while producing, and there is a risk of poor sealing at the four corners of the rectangular sealing ring. Utility Model Content

[0004] The purpose of the utility model is to provide a new flow meter structure in view of the above-mentioned technical problems, so that there is no need to place magnets during production in an injection molding machine, the work of embedding magnets is removed, and the rectangular sealing ring is replaced by a circular sealing ring, thereby improving the production efficiency and sealing of the flow meter.

[0005] In view of this, the utility model provides a new flow meter structure, including: a first shell and a second shell, wherein the outer ends of the first shell and the second shell are respectively installed with a liquid outlet pipe and a liquid inlet pipe, and the utility model is characterized in that a rotor is installed inside the first shell, and two countersunk holes are symmetrically installed on both sides of the rotor surface, and two cylindrical magnets are respectively pressed into the two countersunk holes, and the first shell and the second shell are fixed by a fixing structure.

[0006] In this technical solution, the magnet is designed into a cylinder, two countersunk holes are designed on the top of the rotor, and two cylindrical magnets are pressed into the rotor after it is injection molded. This eliminates the need to place magnets on the injection molding machine during production, and the work of embedding magnets is removed to improve the production efficiency of the rotor and reduce the labor intensity of the staff.

[0007] In the above technical solution, further, the fixing structure includes: two positioning sockets, the two positioning sockets are symmetrically arranged at one end of the first shell, and one end of the second shell is provided with a positioning elastic pin that matches the positioning sockets.

[0008] In the technical solution, the second shell and the first shell are fixedly locked together by inserting the positioning elastic bayonet into the positioning socket.

[0009] In the above technical solution, further, conical columns are provided at both ends of the rotor, and conical holes matching the conical columns are provided on the left and right sides of the inner wall of the first shell, and the rotor is installed in the first shell through the conical columns and the conical holes.

[0010] In the technical solution, the rotor is stably installed in the first housing through the cooperation of the tapered column and the tapered hole.

[0011] In the above technical solution, further, a positioning groove is provided at the outer end of the tapered hole, and a positioning block matched with the positioning groove is provided at one end of the second shell.

[0012] In the present technical solution, the first shell and the second shell are aligned and installed under the action of the positioning groove and the positioning block. Compared with the positioning block, the conical column is prevented from falling in the conical hole, thereby ensuring the stability of the rotor in the shell and reducing the risk of displacement during use.

[0013] In the above technical solution, further, the connection between the first shell and the second shell is a cylindrical structure, the outer wall of the second shell is provided with a sealing groove, and the sealing groove is provided with a circular sealing ring for sealing between the first shell and the second shell.

[0014] In the technical solution, the sealing portion connecting the first shell and the second shell is designed to be cylindrical and the circular sealing ring is replaced, thereby improving the sealing performance and effectively preventing liquid leakage.

[0015] In the above technical solution, further, the rotor includes: a runner, a plurality of blades are circumferentially arranged on the outer wall of the runner, the two conical columns are arranged at the center positions of the left and right ends of the runner, and the two countersunk holes are located on the left and right sides of the conical columns.

[0016] In the present technical solution, a number of blades are provided on the circumference of the outer wall of the impeller so that the blades interact with the fluid flowing through, thereby driving the impeller to rotate. Two conical columns are provided at the center positions of the left and right ends of the rotor. These two conical columns cooperate with the conical holes on the inner wall of the first shell to stably support the rotor and reduce the friction between the rotor and the shell, so that the rotor can rotate more smoothly.

[0017] The beneficial effects of the utility model are:

[0018] 1. By designing the magnet into a cylinder and designing two countersunk holes on the top of the rotor, two cylindrical magnets are pressed into the rotor after it is injected, so that there is no need to place magnets while the injection molding machine is producing. The work of embedding magnets is moved out to improve the production efficiency of the rotor and reduce the labor intensity of the staff.

[0019] 2. The sealing part between the first shell and the second shell is designed to be cylindrical and the circular sealing ring is replaced, thereby improving the sealing performance and effectively preventing liquid leakage. BRIEF DESCRIPTION OF THE DRAWINGS
