[Chinese instrument network meter patent] creative limit, instrumentation invention. Today we will introduce a national invention-invented patent—a thin-sheet ultrasonic water meter, a heat meter, a flow meter measurement sensor, and its use method. The patent was applied by Huizhong Instrument Co., Ltd. and it was authorized on September 28, 2016.
Description of the Invention The present invention relates to a sheet-type ultrasonic water meter, a thermal meter, a measuring sensor for a flow meter and a method of using the same, and particularly to a transducer-specific measuring sensor for measuring a liquid flow rate or heat in a pipeline using an ultrasonic detection technique, belonging to acoustics, transmissions, and the like. Sense of technology.
BACKGROUND OF THE INVENTION At present, the current measurement of liquid flow or heat in a pipeline is to place an ultrasonic sensor in a measuring pipe section, and to measure the liquid flow or heat in the pipe through an ultrasonic detection technology; the ultrasonic water meter, the heat meter, and the flow meter measurement sensor are installed. There are two main forms: flange connection type and wafer type. In the use of these two types of installation, the measurement sensor has the following problems: The measurement sensor installed in the form of a flange connection, due to the operating space related to the flange connection Problems, so its complex structure, large body size, long installation length, operation is not easy; clamp type of installation of the measurement sensor, after installation, need to lock the rotatable ultrasonic sensor, there are moving parts, after installation is not Reliable disadvantages, such as: China Patent No. 6, Patent Name: A card-type ultrasonic fluid flow measurement device, is a clamp-type measurement sensor installed.
SUMMARY OF THE INVENTION The object of the present invention is to provide a sheet-type ultrasonic water meter, a heat meter, a measuring sensor for a flow meter and a method for using the same, which are small in size, simple in structure, easy to install, and have no anti-rotation locking structure, so as to avoid man-made destruction after installation. Affect meter measurement and solve problems in background technology.
The technical scheme of the present invention is: a sheet-type ultrasonic water meter, a heat meter, and a measuring sensor for a flow meter, including a measuring tube section, an ultrasonic sensor, and a beam flow reflector; the measuring tube section is composed of a clip body and a guide beam tube, and is provided with The sensor installation hole, the ultrasonic sensor is arranged in the sensor installation hole; and the beam reflector in the wall of the pipe section of the guide beam pipe is matched with the beam reflector and the ultrasonic sensor.
The figure is a side sectional view of an embodiment of the present invention
The collet body and the guide beam tube described in the invention are an integral structure or a separate combined structure. Plastic material can be used, or other materials can be used; the clip body is located between two sections of the pipeline under test, and the guide beam tube extends into the pipeline to be measured. The outside diameter of the guide beam tube is smaller than the inside diameter of the pipeline under test to facilitate installation and Positioning. The beam segment of the pipe section of the guide beam pipe is provided for improving the flow state of the measured medium in the pipe, which is favorable for measuring by the instrument. The number of beam plates is plural and is arranged along the inner circumference of the wall of the tube segment of the guide beam tube. The beam reflector disposed inside the guide beam pipe is composed of a reflective surface and a support frame, and the reflective surface is disposed on the support frame. The support frame is clamped on the positioning mounting slot of the pipe segment wall in the guide beam pipe, and the reflective surface is Ultrasonic sensors match. The beam reflector may be a continuous structure that penetrates the entire tube section wall along the guide beam tube, or may be an intermittent structure that penetrates the wall of the tube section; the reflection surface and the support frame may be press-formed or welded. The support frame has a planar plate shape and is arranged parallel to the axis of the guide beam tube. The angle of the reflective surface on the support frame is determined according to the position of the ultrasonic sensor matched with the reflective surface. The support frame has a beam flow function and may be a "one" type, and may be a "ten type" type.
The guide beam pipe is provided with a positioning installation slot on the wall of the pipe section. The beam reflector is installed in the guide beam pipe through the positioning installation slot, and the beam reflector matches the ultrasonic sensor. The positioning and installation card slot can be continuous structure along the entire tube wall along the guide beam pipe, or it can be an intermittent structure that penetrates the wall of the pipe section; the positioning and installation card slot can be of the integral type or can be one side of the through type. . The beam reflector can also be fixed on the wall of the tube section of the guide beam tube by welding, interference, bonding, or other forms.
The sensor mounting hole is arranged on the measuring tube section; there are a plurality of ultrasonic sensors, which can be symmetrically arranged in the sensor mounting holes on both sides of the measuring tube section collet body, or can be arranged on the sensor assembly side of the measuring tube section collet body. Hole inside.
The collet body of the present invention is called a collet body because it needs to be sandwiched between two measurement pipes when it is used. The collet body can be a very thin sheet, so the present invention can be referred to as a sheet-type ultrasonic water meter, a hot meter, and a flow meter measurement sensor.
The present invention removes the flange of the measuring pipe segment itself and clamps the very thin clip body between the two flanges through the flanges of the two-segment measuring pipe in the field, and sets the two between the two. Sealing pad to complete the installation of measurement sensors for sheet-type ultrasonic water meters, heat meters, and flow meters.
As the measuring pipe section has the flanges at both ends removed and reduced to the clip body, the external dimensions thereof can be greatly reduced; when the field is installed, the guide beam pipe can be inserted into the pipeline to be measured, and then the flange of the pipe section to be measured in the field will be used. The clip body can be firmly fixed. Since the ultrasonic sensor, the beam reflector and the guide beam tube do not need to rotate to adjust their mutual position relationship after installation, and no moving parts exist, the measurement sensor is safe and reliable after installation, and there is no deadlock by artificial destruction. Organizations affect meter measurement problems. At the same time, because the beam piece with the beam function is arranged in the measuring tube section of the present invention and the beam reflector is assembled, the liquid flow state in the measured pipe can be effectively improved, which facilitates the measurement of the instrument, and has high measurement accuracy and strong adaptability.
The beneficial effects of the present invention are as follows: the measuring pipe segment can not be connected with a blue piece, the external structure is simple, the installation dimension is small, and there is no need for an anti-lock mechanism without moving parts, and the structure is simple and reasonable, the installation is convenient, the man-made destruction is strong, and the reliability is high With high measurement accuracy and adaptability, it can be widely used in liquid metering of ultrasonic water meters, heat meters, and flow meters.
