Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of plate flowmeter, and particularly relates to a plate flowmeter structure based on lightweight design. BACKGROUND

[0002] The flowmeter is called flowmeter in English, and is defined by the National Committee of Scientific and Technological Terminology as an instrument for indicating the flow rate and / or the total amount of fluid in a selected time interval. In simple terms, it is an instrument for measuring the flow rate of fluid in a pipeline or open channel.

[0003] At present, plate flowmeters have been widely used in engineering fields such as petroleum, chemical industry, metallurgy and electric power. The flowmeter mainly consists of a pressure tapping throttling device, a pressure tapping pipe, a three-valve group, a differential pressure transmitter and a support. The pressure tapping throttling device is composed of a pair of flanges that can be connected with the engineering pipeline and a hole plate fixed between the flanges. Each flange is provided with a radial through hole, which constitutes the positive and negative pressure tapping holes, respectively. The three-valve group is composed of positive and negative pressure tapping valves, an adjusting valve and a fluid passage formed by external pipelines between the valves. The differential pressure transmitter is a signal conversion device that can convert the fluid pressure difference signal into an analog electric signal and transmit the electric signal to the terminal display instrument. When used and installed, the pressure tapping throttling device is welded to the pipe connection end through its flanges, the positive and negative pressure tapping holes are connected with the fluid input holes of the positive and negative pressure tapping valves through the pressure tapping pipes, the fluid output holes of the pressure tapping valves are connected with the two pressure tapping chambers of the differential pressure transmitter through two external pipelines, and the adjusting valve is connected between the external pipelines through its fluid inlet and outlet holes.

[0004] However, due to the above-mentioned components, the volume of the plate flowmeter is very large, which not only requires multiple personnel to cooperate during installation, but also has a very large transportation cost. In addition to the need to make special wooden frames for packaging and transportation, the occupied space during transportation is also very large, so that mass transportation cannot be achieved. CONTENT OF THE INVENTION

[0005] To address the aforementioned issues, this paper proposes a lightweight plate flow meter structure. The plate flow meter includes a main pipe and a flow plate. The flow plate is longitudinally positioned at the center of the main pipe, and a detection channel is symmetrically arranged axially within the main pipe. Both sides of the flow plate have internal guide channels. The detection channel is a conduit embedded within the inner wall of the main pipe, and the guide channels are conduits embedded within the inner walls of both the flow plate and the main pipe. The guide channels are symmetrically positioned at the upper and lower ends of the flow plate surface. One end of the guide channel communicates with the surface outline of the flow plate, and the other end communicates with the end of the detection channel. The detection channel is semi-circular in shape, with its two ends located on the outer sides of the flow plate. The left and right axes of the detection channel are... The flow meter is symmetrically arranged on both sides of the main pipe's inner wall. A transversely penetrating insertion seat is located in the middle of the flow channel. A detection rod is inserted into the insertion seat, with one end of the detection rod inside the flow channel and the other end connected to a ring flow meter. The ring flow meter is nested on the outside of the main pipe. By placing the flow meter, which would normally protrude significantly from the outside of the main pipe, in a ring shape on the outside, the flow meter's volume is minimized. Furthermore, the flow channel, which is responsible for transporting and detecting the flow velocity, is moved from the protruding outside to the inner wall of the main pipe, achieving a lightweight, integrated flow meter design. This not only reduces the overall volume but also the weight of the flow channel arrangement, maximizing the flow meter's practical performance.

[0006] The main pipe is a straight cylindrical pipe. A flow plate is located at the center of the vertical axis inside the main pipe. A mounting bracket is installed in the outer ring of the main pipe. The outer side of the main pipe is connected to the annular flow meter through the mounting bracket. By designing the annular flow meter to be installed on the outer side of the main pipe, the overall size of the plate flow meter is minimized.

[0007] The flow plate is shaped like a thick circular ring plate. The outer edge of the flow plate is integrally connected to the interior of the main pipe. The two sides of the flow plate are the inlet and outlet ends, respectively. The flow plate surface is symmetrically equipped with flow channels along the horizontal axis. By setting flow channels for inlet and outlet at both ends of the flow plate, the water flow is guided into the interior of the detection channel. This also ensures that the flow plate is positioned on both sides to achieve accurate detection.

[0008] The diversion channel is a C-shaped right-angle bend. The inner side of the diversion channel is connected to the outer side of the flow plate through a transverse channel, and the outer side of the diversion channel is connected to the inside of the detection channel through a transverse channel. The vertical middle of the diversion channel is connected to the transverse channels on both the inner and outer sides through a vertical channel. Through the bend design of the diversion channel, water can be diverted into the interior of the detection channel to achieve the effect of integrated internal detection.

[0009] The detection channel is a circular channel with a sloping semi-circular arc. The two ends of the detection channel are connected to the flow channels on both sides of the flow plate. The middle of the detection channel is aligned longitudinally with the center of the flow plate. The interior of the detection channel is connected to the outside of the main pipe through a plug-in connector. The arc-shaped detection channel ensures that the water flow has sufficient flow distance to ensure detection accuracy. It also enables the flow to enter from one end of the flow plate and exit from the other end, ensuring unobstructed circulation of the entire flow meter.

[0010] The connector is a cylindrical conductive seat. One end of the connector is integrally connected to the outer surface of the main pipe, and the other end is connected to the inner side of the annular flow meter. The inner side of the connector is equipped with a detection rod that is inserted and conductive. Through the design of the connector, the detection rod can be efficiently inserted and connected to the inside of the detection channel, thereby enabling the annular flow meter to receive the flow velocity signal easily and quickly.

[0011] The annular flow meter is cylindrical in shape. The two inner ends of the annular flow meter are connected to the outer support of the main pipeline through the mounting bracket. The inner middle of the annular flow meter is connected to the detection rod. The annular flow meter is connected to the internal conduction of the detection channel through the detection rod. By using the annular flow meter, the volume of the entire plate flow meter can be reduced, making the entire flow meter into a pipe pile, which is convenient for transportation and installation.

[0012] Beneficial effects:

[0013] By placing the flow meter, which originally needed to be prominently mounted on the outside of the main pipe, in a ring shape on the outside of the main pipe, the flow meter volume is minimized. Furthermore, the detection channel for transporting and measuring flow velocity is placed inside the inner wall of the main pipe from the protruding outside, thus achieving a lightweight and integrated flow meter design. This not only reduces the overall volume but also the weight of the flow channel arrangement, maximizing the practical effect of the flow meter.

[0014] By using an externally mounted annular flow meter design on the outside of the main pipeline, the overall size of the plate flow meter can be minimized.

[0015] By setting inlet and outlet channels at both ends of the flow plate, the water flow is guided into the interior of the detection channel, and the installation on both sides of the flow plate can achieve accurate detection.

[0016] The design of the bent flow channel allows water to flow into the interior of the detection channel, achieving an integrated internal detection effect.

[0017] The arc-shaped detection channel ensures sufficient flow distance for water, guaranteeing detection accuracy. It also allows water to enter from one end of the flow plate and exit from the other, ensuring unobstructed circulation of the entire flow meter.

[0018] The plug-in design allows the detection rod to be efficiently and directly inserted into the internal connection of the detection channel, thus enabling the annular flow meter to easily and quickly receive flow velocity signals.

[0019] By using an annular flow meter, the overall size of the plate flow meter can be reduced, making the entire flow meter a pipe pile, which facilitates transportation and installation. Attached Figure Description
