Description

Technical Field

[0001] This utility model relates to the field of metering valve technology, specifically a high-precision metering valve with a micro flow sensor integrated structure. Background Technology

[0002] A metering valve is a valve device used to precisely control parameters such as flow rate, pressure, and temperature of fluids (such as liquids and gases). Different types of metering valves operate on different principles. For example, the clip-on metering valve is a new generation of precision metering valve based on a completely new concept; the chamber-type metering valve contains a metering chamber, and different metering volumes are achieved through an adjustable-size metering chamber.

[0003] Current metering valves, due to their single adjustable valve body structure, cannot accurately monitor internal components, making them less intelligent and precise in use, and unable to meet the needs of modern intelligent applications. Furthermore, their integrated structure makes them difficult to adjust and install, which is also inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a high-precision metering valve with a micro flow sensor integrated structure, in order to solve the problems mentioned in the background art. The current metering valves are only a single adjustable valve body structure, which makes it impossible to accurately monitor the internal structure. This makes them not intelligent and high-precision enough to meet the needs of modern intelligent use. Furthermore, the integrated structure makes the installation and operation inconvenient due to the lack of adjustable operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-precision metering valve with a miniature flow sensor integrated structure includes a main support body. Side fixing strips are symmetrically fixed on both sides of the main support body. A connecting main block is fixedly connected to the top surface of the main support body. A rotating disk is horizontally mounted on the top of the connecting main block. Fixed connecting pipes are symmetrically connected to both sides of the main support body. An extension pipe is horizontally inserted into the end of the fixed connecting pipe furthest from the main support body. A fixing screw is engaged at the end of the extension pipe furthest from the fixed connecting pipe. A toggle block is symmetrically fixed to the outer side of the fixing screw. A docking base box is vertically connected to the bottom surface of the main support body. A [missing information - likely a device or component] is inserted into the bottom end of the docking base box. The connector has a transmission line connected to its bottom end. The main support body has symmetrically arranged mounting screw holes on its four sides. An internal metering valve is fixedly installed on the inner side of the main support body. A polygonal rotating block is horizontally snapped into the top of the docking box. A fixing screw tube is fixedly installed on the top of the polygonal rotating block. A sensor head is inserted into the top of the fixing screw tube. A flow sensor is fixedly installed on the inner side of the docking box. An insertion interface is provided at the bottom of the docking box. One end of the fixing connecting tube is fixedly connected to an end screw tube. A spring tube body is horizontally fixedly connected to the inner side of the fixing connecting tube. Positioning screws are symmetrically threaded onto the outer side of the fixing connecting tube.

[0007] In a preferred embodiment of this utility model, there are two side fixing strips, which are symmetrically fixed at the two side edges of the main support body. The side edges of the side fixing strips are evenly provided with through holes, and the bottom end of the connecting block is fixedly connected to the center of the top surface of the main support body.

[0008] In a preferred embodiment of this utility model, there are two fixed connecting pipes, and one end of each fixed connecting pipe is connected to the open end of the mounting screw hole on both sides. The extension end pipe and the fixed connecting pipe are arranged in a telescopic rod structure. The actuating block is symmetrically fixed on the outer arc surface of the fixed screw block.

[0009] In a preferred embodiment of this utility model, one end of the connector is inserted into the inner side of the insertion interface to maintain electrical connection, and the mounting screw holes are symmetrically and through-holes located at the center of the four sides of the main support body.

[0010] In a preferred embodiment of this utility model: the bottom end of the fixed solenoid is fixedly connected to the center of the top of the polygonal rotating block, and the top end of the fixed solenoid is threadedly connected to the inner side of the bottom mounting screw hole. The top end of the sensor head extends to the inner side of the inner metering valve, and the bottom end of the sensor head extends to the inside of the flow sensor to maintain an electrical connection.

[0011] In a preferred embodiment of this utility model: the flow sensor and the plug interface are electrically connected to each other; one end of the end screw tube is threadedly fixedly connected to the inner side of the mounting screw hole on the side; one end of the spring tube body is extended and fixedly connected to one end of the extension tube to maintain continuity; the positioning screw is symmetrically threadedly connected to the outside of the fixed connecting tube near the opening end, and the extension end is mated to the outside of the extension tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention completes the installation by setting the main support body's side joints at designated positions and then fixing the side fixing strips in those positions with bolts. After extending the extension tubes on both sides outwards to a designated length, rotating the positioning screws causes the extension ends to press against the outer walls of the extension tubes, thus fixing and positioning them. A fixing block is then attached to one end of the extended tube at the pipe end position, and a moving block is used to complete the installation. After connection, the internal metering valve can be adjusted by rotating the top rotating disc. The bottom is fixed by fixing the top of the docking box. The solenoid is inserted into the mounting screw hole at the bottom. After rotating the polygonal block, the fixed solenoid is fixedly connected inside the mounting screw hole, and one end of the external connector is inserted into the plug interface at the bottom. One end of the transmission line is electrically connected to the controller for control operation. After connection and installation, the sensor head at the top extends into the interior of the inner metering valve for detection and processing. The flow sensor performs precise measurement operations inside the inner metering valve. The use of a split and adjustable structure allows for adjustment and splicing installation as needed. At the same time, the combination with the micro flow sensor structure enables high-precision measurement. Attached Figure Description
