Technical Field

[0001] The utility model belongs to the technical field of flow meters, and particularly relates to an integrated flow meter. Background Art

[0002] Flow meters are widely used in many fields, such as industrial production, environmental protection, energy management, and scientific research. In industrial production, flow meters can be used to monitor and control the fluid flow in the production process to more effectively control the production process. In environmental protection, it can be used to monitor and control the emissions of pollution sources to better protect the environment. In energy management, flow meters can be used to monitor and control the use of energy to better manage energy. In scientific research, it can be used to study the flow characteristics of fluids to better understand the behavior of fluids.

[0003] At present, for the flow meters on the market, the central axis is a metal cylindrical part, the central axis is fixed on the shell, there is a central hole in the center of the runner, the runner is sleeved on the central axis, water enters from the "water inlet" and exits from the "water outlet", and the water flow impacts the runner to make the runner rotate around the central axis. However, the runner and the central axis are separated, which poses a risk of eccentricity. At the same time, the runner is sleeved on the central axis, with a large contact area and large friction. And when installing the upper cover, it is necessary for the staff to adjust or calibrate the assembly position of the upper cover and the shell, which reduces the installation efficiency and lacks a positioning function. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an integrated flow meter to solve the problems of eccentricity and installation positioning caused by the separation of the runner and the central axis in the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An integrated flow meter includes a housing. There is a shaft hole at the center inside the housing. There are two connecting pipes on the outer wall of the housing, and the connecting pipes are communicated with the inside of the housing. A runner is installed inside the housing. There is a central column in the middle of the runner. Conical heads protrude from both ends of the central column. The central column is fitted in the shaft hole. An upper cover is installed above the housing. A positioning component is provided on the outer sides of the housing and the upper cover.

[0007] Further, the positioning component includes a first outer column and a second outer column symmetrically arranged on the housing. Step grooves are provided above the first outer column and the second outer column. The positioning component also includes a first outer ear and a second outer ear symmetrically arranged on the upper cover. Step columns are provided at the bottoms of the first outer ear and the second outer ear.

[0008] Further, a notch is provided on the outer side of the step groove, and an outer convex block is provided on the outer side of the step column. The outer convex block and the notch cooperate with each other.

[0009] Further, the difference between the first outer column and the second outer column is that there is an additional notch on the first outer column; the difference between the first outer ear and the second outer ear is that there is an additional convex block on the first outer ear.

[0010] Further, the two connecting pipes are on the same horizontal line on the outer shell. When the water inlet and the water outlet are on the same horizontal line, it can ensure that the fluid flows stably inside the flowmeter, reducing the measurement error caused by the change of the fluid flow direction or the flow rate change.

[0011] Further, the two connecting pipes are arranged at a right angle on the outer shell. In some specific installation environments, the right-angle design can simplify the installation and connection process of the flowmeter. For example, when the water inlet and the water outlet need to be connected to vertical pipes, the right-angle design can make the connection more convenient and compact.

[0012] The technical solution of the present utility model has the following beneficial effects:

[0013] 1. The runner and the tapered head are set as a whole to ensure concentricity and good centering: The neutral accuracy of the tapered mandrel is relatively high, which helps to improve the assembly accuracy and stability. At the same time, due to the tapered structure, the contact area of the tapered head is greatly reduced, making the load distribution more uniform, thus reducing the friction caused by local stress concentration, so that the mechanical equipment has a longer service life and lower usage cost.

[0014] 2. The notch and the convex block need to cooperate with each other, so only the first outer column can be assembled with the first outer ear. The use of the notch and the convex block plays a unique positioning function. With the unique positioning function, the assembler does not need to perform complex adjustment or calibration operations, and only needs to insert the convex block into the notch correspondingly to complete the assembly. This greatly simplifies the assembly process, improves the assembly efficiency, and reduces potential errors during the assembly process. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0022] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1:

[0024] Referring to Figure 1 , an integrated flowmeter includes a housing 10. A shaft hole 101 is provided at the center inside the housing 10. Two connecting pipes 11 are provided on the outer wall of the housing 10, and the connecting pipes 11 are in communication with the inside of the housing 10; the functions of the two connecting pipes 11 are respectively to serve as a water inlet and a water outlet, so as to complete the water flow into the housing 10 and then discharge from the housing 10 to calculate the flow rate.

[0025] Still referring to Figures 1 - 3 , a runner 16 is installed inside the housing 10. A central column 18 is provided in the middle of the runner 16, and conical heads 19 protrude from both ends of the central column 18. The central column 18 is fitted in the shaft hole 101, and an upper cover 20 is installed above the housing 10;

[0026] In the above solution, blades 17 are equidistantly distributed on the outside of the runner 16. When the medium fluid enters through the water inlet and passes through the housing 10 of the sensor, it will impact the blades 17 and cause the blades 17 to rotate. At the same time, the blades are magnetically conductive. When it is in the magnetic field of the signal detector, the rotating blades will continuously cut the magnetic coil, causing the magnetic flux to change periodically, and current will be generated at both ends of the coil. These currents are then amplified and shaped by an amplifier to form a continuous rectangular pulse wave with a certain amplitude and are transmitted far to the display instrument to display the instantaneous flow rate and cumulative amount of the fluid.

[0027] When installing the runner 16, place the runner 16 inside the housing 10. At the same time, the tapered head 19 at one end will enter the shaft hole 101 for positioning. Then, install the upper cover 20 above the housing 10. There is also a shaft hole 101 at the center of the top of the upper cover 20 for positioning the tapered head 19 on the other side. The structure of the tapered head 19 is conical, protruding from both ends on the upper and lower sides of the runner 16. Compared with cylindrical bearings, tapered bearings have stronger capabilities to withstand radial and axial loads. Their inward oblique angle is larger, making them more capable of withstanding radial, axial, and reverse torques. The installation and adjustment of tapered shafts are relatively simple. This characteristic makes the installation and maintenance of tapered shafts more convenient in practical applications. The runner 16 and the tapered head 19 are set as a whole to ensure concentricity and good alignment: the neutral accuracy of the tapered mandrel is relatively high, which helps to improve the assembly accuracy and stability. At the same time, due to the conical structure, the contact area of the tapered head 19 is greatly reduced, making the load distribution more uniform, thus reducing the friction caused by local stress concentration, so that the mechanical equipment has a longer service life and lower usage cost.

[0028] Furthermore, a positioning component is provided on the outer sides of the housing 10 and the upper cover 20. The positioning component includes the first outer column 12 and the second outer column 15 symmetrically arranged on the housing 10. Step grooves 13 are provided above the first outer column 12 and the second outer column 15. The positioning component also includes the first outer ear 21 and the second outer ear 23 symmetrically arranged on the upper cover 20. Step columns 211 are provided at the bottoms of the first outer ear 21 and the second outer ear 23.

[0029] In the above solution, when installing the upper cover 20, fit the step column 211 concentrically into the step groove 13 for installation. The positioning fit between the step column 211 and the step groove 13 helps to reduce installation errors. The tight fit between the step column 211 and the step groove 13 can make the connection between the upper cover and the housing or other components tighter and more stable, enhancing the stability and reliability of the overall structure. This design helps to reduce loosening or deformation of the equipment caused by vibration or impact during operation. A sealing ring 25 is placed between the contacts of the upper cover 20 and the housing 10. The sealing ring 25 improves the sealing performance between the upper cover 20 and the housing 10 to prevent leakage problems.

[0030] Furthermore, a notch 14 is provided on the outer side of the step groove 13, and an outer convex block 22 is provided on the outer side of the step column 211. The outer convex block 22 and the notch 14 cooperate with each other. The difference between the first outer column 12 and the second outer column 15 is that there is one more notch 14 on the first outer column 12. The difference between the first outer ear 21 and the second outer ear 23 is that there is one more outer convex block 22 on the first outer ear 21.

[0031] In the above solution, during the assembly process of the upper cover 20, the first outer column 12 needs to be fitted with the first outer ear 21. Since the notch 14 and the outer convex block 22 need to be fitted with each other, only the first outer column 12 and the first outer ear 21 can be assembled in a matching manner. The use of the notch 14 and the outer convex block 22 serves a unique positioning function. With this unique positioning function, assemblers do not need to perform complex adjustment or calibration operations. They only need to insert the outer convex block 22 into the notch 14 correspondingly to complete the assembly. This greatly simplifies the assembly process, improves the assembly efficiency, and reduces potential errors during the assembly process. Moreover, through holes are provided in the stepped column 211 and the first outer ear 21, the inner wall of the stepped groove 13 has a threaded structure, and a nut 24 is connected in the through hole. After the upper cover 20 is assembled and fitted, the nut 24 is passed through the through hole and screwed into the stepped groove 13.

[0032] Embodiment Two:

[0033] Refer to Figure 4 , the two connecting pipes 11 are on the same horizontal line on the outer shell 10.

[0034] In this embodiment: When the water inlet and the water outlet are on the same horizontal line, it can ensure that the fluid flows in a stable state inside the flowmeter, reducing measurement errors caused by changes in the fluid flow direction or flow rate. This horizontal installation method helps to maintain the stability of the fluid flow, thereby improving the measurement accuracy of the flowmeter. For fluids that are prone to generating bubbles, setting the water inlet and the water outlet on the same horizontal line can reduce the interference of bubbles on the measurement results. Because the presence of bubbles may change the density or flow state of the fluid, thereby affecting the measurement accuracy of the flowmeter. Horizontal installation helps to reduce the generation and accumulation of bubbles.

[0035] Embodiment Three:

[0036] Refer to Figure 5 , the two connecting pipes 11 are arranged at a right angle on the outer shell 10.

[0037] In this embodiment: The right-angle design can reduce the direct impact of the fluid at the water inlet and the water outlet, thereby reducing the impact force of the fluid on the internal structure of the flowmeter. The right-angle design helps to improve the distribution of the fluid inside the flowmeter, making the fluid pass through the flowmeter more evenly. This can improve the measurement accuracy and stability, and reduce measurement errors caused by uneven fluid distribution. In certain specific installation environments, the right-angle design can simplify the installation and connection process of the flowmeter. For example, when the water inlet and the water outlet need to be connected to vertical pipes, the right-angle design can make the connection more convenient and compact.

[0038] Embodiment Four:

[0039] The two connecting pipes 11 can also be arranged at any angle.

[0040] In summary, through the arrangement of the multi-style connecting pipes 11, the customer has more choices for the product, and the angle of the connecting pipe 11 can be selected according to the actual installation needs.

[0041] The specific implementation process of this embodiment is as follows:

[0042] During use, when installing the runner 16, place the runner 16 inside the housing 10. At the same time, the tapered head 19 at one end will enter the shaft hole 101 for positioning, and then install the upper cover 20 above the housing 10.

[0043] When installing the upper cover 20, concentrically fit the stepped column 211 into the stepped groove 13 for installation. The positioning fit between the stepped column 211 and the stepped groove 13 helps to reduce the installation error. The tight fit between the stepped column 211 and the stepped groove 13 can make the connection between the upper cover and the housing or other components more tight. It is necessary to cooperate the first outer column 12 with the first outer ear 21. Since the notch 14 and the outer convex block 22 need to cooperate with each other, the first outer column 12 and the first outer ear 21 can only be assembled in cooperation. The use of the notch 14 and the outer convex block 22 serves a unique positioning function.
