Description

Technical Field

[0001] This utility model relates to the field of flow meter technology, and more specifically to a turbine flow meter. Background Technology

[0002] A flow meter is an instrument used to measure the flow rate of fluids (liquid, gas, steam) in pipes or open channels. It is widely used in industrial production, environmental protection, energy metering, transportation and other fields. The core function of a flow meter is to convert fluid flow rate into a measurable signal through physical principles (such as mechanics, electricity, acoustics, and thermodynamics), providing key data support for production process control, energy management, environmental protection and other fields. A turbine flow meter is a type of flow meter. It is a velocity-type instrument that measures flow rate based on the rotation of a turbine driven by fluid power. Its core principle is to convert the flow velocity into the turbine speed, and then convert the speed into an electrical signal that is proportional to the flow rate through a sensor.

[0003] The impeller of a turbine flow meter is a key component. Over time, the impeller will lose accuracy due to wear, so it needs to be replaced after the impeller wears out. However, existing turbine flow meters do not make it convenient to replace the impeller, and each disassembly of the flow meter is quite cumbersome. Secondly, after the impeller is replaced, it is not easy to position it to make it stable, which requires constant adjustment during replacement and is inconvenient to use. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a turbine flow meter to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a turbine flow meter, including a flow meter body and a measuring component. The measuring component is fixedly connected inside the flow meter body, and a sensor component is fixedly connected to the top center of the flow meter body. Connecting flanges are fixedly connected to both sides of the flow meter body. The measuring component includes a front guide member, an impeller is movably sleeved on one side of the front guide member, and a rear guide member is movably sleeved on one side of the impeller. Uniformly distributed straight guide grooves are opened on both sides of the rear guide member, and uniformly distributed guide holes are opened on both sides of the rear guide member near the edge. A rear limiting block is fixedly connected to the top and bottom of one side of the rear guide member.

[0006] Furthermore, the front guide member has evenly distributed spiral grooves on both sides, a bearing is fixedly connected to the inside of the middle of one side of the front guide member, and a front limiting block is fixedly connected to the top and bottom of the other side of the front guide member. The front limiting block has the same structure as the rear limiting block.

[0007] Furthermore, a rotating shaft is fixedly connected to the middle of both sides of the impeller, and the rotating shaft is adapted to the bearing.

[0008] Furthermore, the flow meter body includes a first housing, with first threaded openings on both sides of the interior of the first housing, and limiting openings near the sides of the interior of the first housing. The inner wall of the limiting opening is in contact with the outer surface of the front guide, and the inner wall of the middle part of the interior of the first housing is adapted to the outer surface of the impeller.

[0009] Furthermore, the first housing has an installation port at the top center, which is threaded to the bottom of the sensor assembly. The second housing is fixedly connected to both sides of the first housing, and a connecting thread is provided on one outer surface of the second housing, which is compatible with the first threaded opening.

[0010] Furthermore, a connecting ring plate is fixedly connected to one side of the second housing. Limiting grooves are formed at the top and bottom of the connecting ring plate. The limiting grooves cooperate with the rear limiting block. A second threaded opening is formed on the other side of the interior of the second housing. The second threaded opening is adapted to the connecting flange.

[0011] Furthermore, the sensor assembly includes a threaded rod, the top of which is fixedly connected to a lower housing, the interior of which is electrically connected to sensor circuitry, and the top of which is fixedly connected to an encapsulation housing.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by incorporating a measuring component, uses the spiral groove on the front guide to create a stable swirling flow of fluid before it enters the impeller, balancing the fluid velocity distribution and reducing turbulence and eddies. The straight groove and guide hole on the rear guide further stabilize the fluid flow, reducing the impact of turbulence. This allows the fluid to pass through the impeller more smoothly, optimizing the measurement environment.

[0014] 2. This utility model features a flow meter body. The front guide component is quickly installed by engaging with the limiting groove on the second housing via a front limiting block on the front guide component. The first threaded port is threaded into the connecting thread, allowing the first housing to quickly fix the front guide component before installing it on the second housing. The rear guide component is installed on the impeller by inserting the impeller's rotating shaft into the bearing. This facilitates quick installation and removal of the flow meter, rapid impeller replacement, and improved efficiency.

[0015] 3. This utility model features a flow meter body. Through the cooperation of the front limiting block and the limiting groove, the front guide component is quickly positioned. Then, it is installed on the first housing through the second housing. The limiting port cooperates with the outer surface of the front guide component to fix the front guide component. After the impeller is installed on the front guide component through the inside of the first housing, the rear guide component is placed. This facilitates the rapid positioning and stabilization of the impeller position, reduces tedious debugging, and improves efficiency. Attached Figure Description
