Description

Technical Field

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

[0002] Turbine flow meters are mainly used to measure the volumetric flow rate of fluids (such as liquids or gases). They drive the turbine blades to rotate through the fluid momentum angular momentum, and the rotational speed is proportional to the flow rate. They can display the instantaneous flow rate and cumulative total in real time. They are widely used in flow monitoring and control in the petroleum, chemical, power, and gas industries. They are especially used as a legal metrology tool in trade settlement. The sensor is an important component of the turbine flow meter, integrating the turbine, guide vane, bearing, and signal detector to complete the flow signal acquisition.

[0003] Insufficient technology: To adapt to complex industrial environments, turbine flow meters are usually made of stainless steel, providing IP67 protection and explosion-proof design. However, stainless steel is a thermally conductive metal. When turbine flow meters are used to detect flow in high-temperature pipelines, the signal detector is installed on top of the sensor. However, the length of existing sensors is limited. During the use of turbine flow meters, heat in the pipeline can easily be transferred to the signal detector through the sensor. The signal detector contains a large number of precision electronic components that are easily damaged by high temperatures, affecting the service life and measurement accuracy of the turbine flow meter.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The turbine flow meter sensor involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1 to 6This utility model provides a turbine flow meter sensor, including a device body 1 and a sensing mechanism 2. The top end of the device body 1 is threadedly connected to the bottom end of the sensing mechanism 2. The device body 1 includes a mounting cylinder 101, and a turbine blade 105 is movably sleeved on the inner side wall of the mounting cylinder 101. A connecting seat 103 is fixedly connected to the top end of the mounting cylinder 101 corresponding to the position of the turbine blade 105. The length of the sensing mechanism 2 is 20 centimeters. The sensing mechanism 2 includes a mounting post 201, and an external thread 205 is provided at the bottom end of the mounting post 201. The side of the external thread 205 is threadedly connected to the inner side wall of the connecting seat 103. A magnetoelectric induction coil 206 is fixedly connected to the inner side wall of the mounting post 201, and the magnetoelectric induction coil 206 is close to the bottom of the mounting post 201. A mounting box 203 is fixedly connected to the top end of the mounting post 201. A signal detection processor 208 is movably connected to the inner side wall of the mounting box 203. A wire 209 is fixedly connected to the bottom end of the signal detection processor 208. The top of the magnetoelectric induction coil 206 is fixedly connected. The side of the mounting post 201 is provided with heat sink 202. The sensing mechanism 2 is fixed inside the connecting seat 103 by external thread 205. At this time, the magnetoelectric induction coil 206 is close to the turbine blade 105. The main body of the equipment 1 is connected to the pipeline. During the detection process, the liquid or gas drives the turbine blade 105 to rotate, so that the turbine blade 105 continuously cuts the magnetic lines of force generated by the magnetoelectric induction coil 206 to generate periodic electrical pulse signals. The electrical pulse signals are transmitted to the signal detection processor 208 through the wire 209. The pulse signals are amplified and filtered, and converted into instantaneous flow and cumulative flow data through a preset algorithm. During use, the sensing mechanism 2 is kept at a long length so that the signal detection processor 208 is far away from the main body of the equipment 1. The heat sink 202 is provided on the side of the mounting post 201 to increase the contact area with the air, improve the heat dissipation of the sensing mechanism 2, reduce the heat transfer to the signal detection processor 208, and ensure the operation of the signal detection processor 208.

[0023] The sensing mechanism 2 is made of stainless steel and is integrally machined to ensure its overall strength.

[0024] The mounting post 201 has a heat insulation filler 207 inside its side, and the wire 209 is located at the center of the heat insulation filler 207. Heat is transferred through the housing of the sensing mechanism 2. The heat insulation filler 207 isolates the electronic components inside the sensing mechanism 2 from the housing of the sensing mechanism 2, thus avoiding any impact on the electronic components.

[0025] Among them, a hexagonal locking block 204 is fixedly connected to the side of the mounting column 201. The hexagonal locking block 204 facilitates the operation of the sensing mechanism 2 by the operator. A fastening head 102 is threadedly connected to the inner wall of the side of the mounting cylinder 101. The fastening head 102 is provided with a fastening groove 107 on its side. The fastening head 102 is installed at both ends of the mounting cylinder 101 by a screw.

[0026] The inner side wall of the mounting cylinder 101 is movably connected to a flow guide seat 106. The side of the flow guide seat 106 is movably connected to the side of the fastening head 102. Both ends of the turbine blade 105 are provided with flow guide seats 106 to guide the liquid or gas flowing through the inside of the mounting cylinder 101, so that it flows through the inclined hole on the turbine blade 105 and drives the turbine blade 105 to rotate. The side of the flow guide seat 106 is in close contact with the side of the fastening head 102. The two flow guide seats 106 clamp the turbine blade 105 so that the turbine blade 105 is located at the center of the mounting cylinder 101.

[0027] The guide seat 106 has a positioning protrusion 104 fixedly connected to its side. The fastening head 102 has a slot 108 on its side corresponding to the position of the positioning protrusion 104. The side of the slot 108 is movably connected to the side of the positioning protrusion 104. The positioning protrusion 104 is inserted into the slot 108 to fix the guide seat 106, so as to avoid the rotation affecting the rotation of the turbine blade 105 and ensure the accuracy of the measurement.

[0028] The working principle of this utility model is as follows: When assembling the main body 1, the turbine blade 105 is placed inside the mounting cylinder 101, the guide seat 106 is placed on the side of the fastening head 102 and the positioning protrusion 104 is engaged in the slot 108. The fastening head 102 is fixed to both ends of the mounting cylinder 101 by threads, and the guide seats 106 on both sides are clamped to prevent shaking. The sensing mechanism 2 is fixed inside the connecting seat 103 by external threads 205. At this time, the magnetoelectric induction coil 206 is close to the turbine blade 105. The main body 1 is then connected to the pipeline. During the detection process, liquid or gas flows through the oblique hole on the turbine blade 105 after being guided by the guide seat 106, which drives the turbine blade 105 to rotate and push the turbine blade 105. The rotation of the turbine blades 105 causes them to continuously cut the magnetic lines of force generated by the magnetoelectric induction coil 206, producing periodic electrical pulse signals. These signals are then transmitted to the signal detection processor 208 via the wire 209. The pulse signals are amplified, filtered, and converted into instantaneous and cumulative flow data using a preset algorithm. The sensing mechanism 2 is kept at a relatively long length, keeping the signal detection processor 208 away from the main body 1. Heat sinks 202 are installed on the side of the mounting column 201 to increase the contact area with air and improve heat dissipation of the sensing mechanism 2. Furthermore, the heat insulation filler 207 isolates the internal electronic components and housing of the sensing mechanism 2, reducing heat transfer to the signal detection processor 208 and ensuring its proper operation.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
