Through the action of the filter mechanism, impurities in the liquid can be filtered out, thereby achieving the purpose of protecting the float from floating up and down normally and ensuring measurement.

[0004] However, when cleaning the device according to the above technology, the pipe body 1 and the pipe body 2 are separated and disassembled by loosening or tightening the bolts, and the float and the filter are taken out for cleaning. Although it seems to simplify the cleaning process, the filter is a filtering device in the flow meter, which is used to block impurities and particulate matter in the fluid. This requires frequent disassembly and cleaning of the filter without frequent disassembly and cleaning of the float. The disassembly of the float by the above device may increase the risk of damage to it, such as scratching, deformation or weakening of magnetism, which will affect the accuracy and service life of the flow meter, and its practicality is generally poor.

A notch 215 is provided at the top front side of the flow meter body 1, and a plugging plate 214 is movably mounted inside the notch 215. A front plate 216 is fixedly mounted on the outer side of the plugging plate 214, and the front plate 216 is made of metal. A sealing gasket is fixedly mounted on the inner side of the front plate 216. An arc plate 212 is fixedly mounted on the rear side of the top inner side of the flow meter body 1. An arc groove 213 is provided on the side of the arc plate 212 close to the filter screen 211, and a sealing gasket is fixedly mounted on the inner side of the arc groove 213. A positioning assembly is provided on the outer side of the plugging plate 214 for positioning the filter screen 211.

[0027] The fixing assembly 22 is arranged on the outside of the flow meter body 1 for fixing the position of the front plate 216. The positioning assembly includes plugs 218 fixedly installed on the left and right sides of the blocking plate 214. Slots 217 are provided on the left and right sides of the notch 215, and a sealing gasket is fixedly installed on the inner side of the slot 217. Magnets 219 are fixedly installed on the left and right sides of the top of the outer side of the flow meter body 1. The outer side of the filter 211 is tightly attached to the inner side of the arc groove 213, and the filter 211 is tightly attached to the arc groove 213 to improve its sealing performance and prevent debris from flowing in. The interior of the inlet flow meter body 1 affects the accuracy of detection. The inner side of the blocking plate 214 is movable through the inside of the slot 215 and is fixedly installed on the outside of the filter 211. The outer side of the plug 218 is tightly attached to the inner side of the slot 217. The left and right ends of the front plate 216 are both adsorbed on the front side of the magnet 219, and the front plate 216 can pre-position the position of the filter 211 through the magnetic force of the magnet 219. The inner side of the front plate 216 is tightly attached to the outer side of the flow meter body 1, and the front plate 216 can prevent the fluid from flowing out of the slot 215.

[0028] The provided blocking plate 214 and front plate 216 facilitate the disassembly and installation of the filter 211. When disassembly is required, remove the fixing assembly 22, pull out the front plate 216, and pull the blocking plate 214 out of the inside of the slot 215. Then the slot 215 will drive the filter 211 to be pulled out of the inside of the flow meter body 1, which is convenient for subsequent cleaning. After the cleaning is completed, pick up the front plate 216 and insert the filter 211 through the slot 215 into the inside of the flow meter body 1. At this time, the plug 218 will be inserted into the slot 217. At the same time, the two ends of the front plate 216 will be adsorbed on the magnet 219 to position the filter 211. Then the installation and fixation can be completed through the fixing assembly 22, which reduces the risk of damage to the float and improves the accuracy and service life of the flow meter body 1.

[0029] The second embodiment is different from the first embodiment in that the fixing assembly 22 includes an outer cylinder 221 fixedly mounted on the outside of the flow meter body 1, a movable groove 224 is provided on the front side of the outer cylinder 221, and the opening of the movable groove 224 is larger than the notch 215, a slide 225 is slidably mounted inside the movable groove 224, and the cross section of the slide 225 is I-shaped, a fastening bolt 226 is threadedly mounted on the front side of the slide 225, and a pressure plate 222 is movably mounted on the rear end of the fastening bolt 226, and the left and right sides of the pressure plate 222 are fixed. A limiting plate 223 is installed, and the rear side of the pressure plate 222 is tightly attached to the front side of the front plate 216. The rear end thread of the fastening bolt 226 passes through the front side of the slide plate 225 and is movably installed on the front side of the pressure plate 222. The rotating slide plate 225 can drive the pressure plate 222 to move backward, and then the pressure plate 222 will be tightly attached to the outer side of the front plate 216 to fix the front plate 216. The structure is simple and easy to fix. The opposite sides of the limiting plate 223 are tightly attached to the left and right sides of the slide plate 225, and the movement trajectory of the pressure plate 222 can be limited by the limiting plate 223.

[0030] The position of the front plate 216 can be fixed by the provided pressure plate 222 and fastening bolts 226. When in use, the sliding slide 225 is moved to the front side of the front plate 216, and then the fastening bolts 226 are rotated to limit the pressure plate 222 through the limit plate 223. Then the pressure plate 222 will be squeezed on the front side of the front plate 216 so that the inner side of the front plate 216 is tightly attached to the outer side of the flow meter body 1 and the position of the blocking plate 214 is fixed.

When it is necessary to clean the debris on the filter screen 211, rotate the fastening bolt 226 to drive the pressure plate 222 to move it away from the front side of the front plate 216, then slide the limit plate 223 to move it away from the front side of the front plate 216, and then pull out the front plate 216 to pull the blocking plate 214 out of the inside of the slot 215, and then the slot 215 will drive the filter screen 211 to be pulled out of the inside of the flow meter body 1, and then the debris on the filter screen 211 can be cleaned. After completion, pick up the front plate 216 and insert the filter 211 through the slot 215 into the interior of the flow meter body 1. At this time, the plug 218 will be inserted into the slot 217. At the same time, the two ends of the front plate 216 will be adsorbed on the magnet 219 to position the filter 211. Then slide the slide 225 to the front side of the front plate 216. Then rotate the fastening bolt 226 in the opposite direction to limit the pressure plate 222 through the limit plate 223. Then the pressure plate 222 will be squeezed on the front side of the front plate 216 to make the inner side of the front plate 216 close to the outer side of the flow meter body 1 and fix the position of the blocking plate 214. Then stop rotating the fastening bolt 226 to fix the position of the pressure plate 222 to complete the installation.
