Description

Technical Field

[0001] This application relates to the field of integrated balanced flow meters, and more particularly to a corrosion-resistant integrated balanced flow meter. Background Technology

[0002] The integrated balanced flow meter is a revolutionary differential pressure flow instrument, originating from the design concept of the liquid oxygen flow meter used in the main engine of the US Space Shuttle in 2003. It employs a unique balanced rectification design, featuring high accuracy, low noise, and minimal pressure loss, and is widely used in industrial production.

[0003] Existing integrated balanced flow meters may experience blockages due to impurities in the fluid, leading to a loss of balance. While filters are used to block these impurities, they can also become clogged and corroded over time, necessitating replacement or cleaning. However, current filters are typically secured with bolts, leaving room for improvement in ease and flexibility in installation and removal. Utility Model Content

[0004] In order to enable the balanced flow meter to be quick to install and disassemble and to be corrosion resistant, this application provides a corrosion resistant integrated balanced flow meter.

[0005] The corrosion-resistant integrated balanced flow meter provided in this application adopts the following technical solution: A corrosion-resistant integrated balanced flow meter includes a flow meter and a mounting base installed on the flow meter. Two mounting pipes are symmetrically arranged on one side of the mounting base. A connecting pipe can be detachably installed on one side of each of the two mounting pipes. A flow pipe is provided at one end of each of the two connecting pipes. A snap-fit ​​mechanism is provided inside the mounting pipe.

[0006] The locking mechanism includes two mounting boxes symmetrically fixedly installed inside the mounting tube. Each mounting box contains a sleeve, and each sleeve contains a piston rod that is slidably installed. Each sleeve is fitted with a positioning spring. The output ends of each piston rod are fixedly fitted with the same first wedge block. The mounting tube contains a filter screen. Two second wedge blocks are symmetrically fixedly installed on one side of the filter screen and are adapted to the corresponding first wedge blocks. A locking groove is formed on one side of the first wedge block, and a locking block adapted to the locking groove is fixedly installed on one side of the second wedge block. A driving mechanism is provided at one end of the piston rod.

[0007] By adopting the above technical solution, two second wedge blocks on one side of the filter screen are inserted into the corresponding mounting box, which will push the corresponding first wedge block to move.

[0008] Preferably, the driving mechanism includes a connecting plate fixedly installed at one end of the piston rod, and one end of the piston rod passes through one side of the mounting box. A third wedge block is fixedly installed on one side of the connecting plate. A pressing post is provided through the filter screen frame.

The two ends of the return spring are respectively fixedly installed on the filter screen frame and the button on the side close to each other.

[0009] By adopting the above technical solution, the fourth wedge block can be reset by setting a reset spring. With the cooperation of the locking groove and the locking block, self-locking installation can be completed. By pressing the button, the pressing column and the fourth wedge block will move, and the third wedge block will be pushed to one side. This will drive the piston rod and the first wedge block to move as well, thus releasing the self-locking of the first and second wedge blocks, making it easier to disassemble and clean them later. This improves the convenience and flexibility of use.

[0010] Preferably, a first mounting ring and a second mounting ring are symmetrically fixedly installed on the outer side of the connection port of the mounting pipe and the connecting pipe. A corresponding first mounting plate and a second mounting plate are fixedly installed on the first mounting ring and the second mounting ring. The first mounting plate and the second mounting plate have the same length. A mounting groove is opened on one side of the second mounting plate, and a rectangular plate is fixedly installed on the mounting groove.

[0011] By adopting the above technical solution and setting up an installation slot, an auxiliary installation function can be achieved.

[0012] Preferably, two slots are symmetrically opened on one side of the rectangular plate, and a plug is slidably installed in each of the two slots. Both plugs are fixedly installed on one side of the first mounting plate.

[0013] By adopting the above technical solution, the installation can be strengthened by setting slots and plugs.

[0014] Preferably, two rack plates are symmetrically slidably installed in the mounting groove, and gears that mesh with the two rack plates are rotatably installed in the mounting groove. A positioning plate is fixedly installed on one side of each of the two rack plates, and each of the two positioning plates is in contact with a corresponding insert block.

The two positioning plates moving away from each other will position and install the two inserts, thereby improving the ease of assembly during use.

[0016] Preferably, each of the two insert blocks has a slot on one side, and a block is slidably installed in each of the two slots. Each of the two blocks is fixedly connected to the corresponding positioning plate.

[0017] By adopting the above technical solution and setting up slots and blocks, the stability and firmness of the positioning installation can be enhanced.

[0018] Preferably, the outer surface of the exposed side of the rotating column is threaded, and a nut is screwed onto the thread.

[0019] By adopting the above technical solution, the position of the rotating column can be positioned and installed by rotating the nut, thereby improving the stability and firmness of the installation.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application employs a filter screen and other components. First, the filter screen is installed inside the installation tube, causing two second wedge blocks on one side of the filter screen to insert into the corresponding installation boxes. This pushes the corresponding first wedge block and piston rod to move. Through the cooperation of the locking groove and locking block, self-locking installation is achieved. By pressing the button, the pressing column and fourth wedge block move, pushing the third wedge block to one side. This, in turn, moves the piston rod and first wedge block, thus releasing the self-locking of the first and second wedge blocks. This facilitates disassembly and cleaning later, thereby improving the convenience and flexibility of use.

[0044] By splicing the mounting tube 3 and the connecting tube 4, the two inserts 13 on the first mounting plate 8 will be inserted into the corresponding slots 12 on the second mounting plate 9. At this time, the rotating column 26 can be rotated, which will drive the gear 22 to rotate. The rotation of the gear 22 will drive the two rack plates 21 and the two positioning plates 23 to move away from each other. The two positioning plates 23 moving away from each other will position and install the two inserts 13, thereby improving the ease of assembly during use. Then, the rotating nut 28 can be rotated, and the position of the rotating column 26 can be positioned and installed through the nut 28, thereby improving the stability and firmness of the installation.
