[0002] A pressure transmitter mainly consists of three parts: a pressure measuring element sensor, a measuring circuit, and a process connector. It can convert physical pressure parameters such as gas and liquid sensed by the pressure measuring element sensor into standard electrical signals to supply secondary instruments such as indicating alarm instruments, recorders, and regulators for measurement, indication, and process adjustment.

[0003] For the existing Chinese utility model patent with the reference publication number: CN220649871U, it discloses a pressure transmitter with a filtering structure, including: an installation box; a cleaning component, the bottom of the cleaning component is fixedly connected to the inside of the installation box, the cleaning component includes a motor, the bottom of the motor is fixedly connected to the inside of the installation box, the output shaft of the motor is fixedly connected with a lead screw, the top of the lead screw is rotatably connected to the inside of the installation box, and the circumferential surface of the lead screw is threadedly connected with a screw block. The utility model provides a pressure transmitter with a filtering structure. By the rotation of the motor driving the rotation of the lead screw, the rotation of the lead screw drives the movement of the screw block, the movement of the screw block drives the movement of the cleaning plate, and the movement of the cleaning plate drives the slider to slide on the circumferential surface of the guide rod. The up and down movement of the cleaning plate realizes the cleaning of the data display screen of the pressure transmitter. The cleaning plate cleans the dust and debris on the surface of the data display screen of the pressure transmitter, which is convenient for observing the measurement data of the data display screen and improves the accuracy of data reading.

[0004] Although the above-mentioned pressure transmitter with a filtering structure solves the problem that it is not convenient to clean the data display screen of the pressure transmitter when some existing pressure transmitters with a filtering structure are in use by the rotation of the motor driving the rotation of the lead screw, the existing pressure transmitters with a filtering structure are not convenient to clean the filtering structure, which easily leads to the blockage of the filtering structure and affects the flow rate.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Combined with the attached Figures 1-5, in this embodiment, a pressure transmitter with a filtering structure includes: an installation pipe 1. Two control valves 11 are fixedly installed on both sides of the middle of the installation pipe 1. A connection groove 12 is fixedly installed in the middle of the installation pipe 1.

A side pipe 14 is fixedly installed on one side of the installation pipe 1. The side pipe 14 is in the shape of a "C". Two switching valves 15 are fixedly installed on both sides of the side pipe 14.

[0026] Specifically, by closing the two control valves 11 and opening the two switching valves 15 at the same time, the liquid can pass through the inside of the side pipe 14, thereby bypassing the connection groove 12, so as to facilitate the cleaning of the filtering structure.

[0027] An insertion block 2 is movably connected inside the connection groove 12. The insertion block 2 is in the shape of a "C". An installation plate 21 is fixedly installed on one side of the bottom of the insertion block 2. The installation plate 21 is in the shape of a "C".

The connection ring 23 is in the shape of a ring. A small filter screen 24 is fixedly installed inside the connection ring 23.

[0028] Specifically, the insertion block 2 is used for support, the installation plate 21 supports the large filter screen 22, the small filter screen 24 in the middle of the connection ring 23 inside it can filter out smaller impurities in the water flow, and the large filter screen 22 can filter out larger particles.

[0029] A sealing block 3 is fixedly installed on the top of the insertion block 2. The sealing block 3 is in the shape of a "mouth".

[0030] A cover plate 31 is fixedly installed on the top of the sealing block 3. A handle 32 is fixedly installed in the middle of the top of the cover plate 31.

[0031] Four threaded rings 33 are fixedly installed inside the four sides of the cover plate 31. An installation bolt 34 is movably connected inside the threaded ring 33.

[0032] Specifically, the cover plate 31 can be fixed on the top of the connecting plate 13 through the installation bolt 34. The sealing block 3 can seal the gap, avoiding the problem of water leakage. The handle 32 can facilitate the removal of the insertion block 2.

[0033] A connecting pipe 4 is fixedly installed on one side of the installation pipe 1. An installation seat 41 is fixedly installed on one side of the top of the connecting pipe 4.

[0034] A pressure transmitter main body 42 is fixedly installed on the top of the installation seat 41.

[0035] An inductor 43 is fixedly installed at the bottom of the pressure transmitter main body 42.

[0036] Specifically, the water flow can be conveyed through the connecting pipe 4. The pressure transmitter main body 42 is detected through the sensor 43 at its bottom, and the pressure transmitter main body 42 is installed through the mounting base 41, improving the practicability of the pressure transmitter with a filtering structure.

[0037] Working principle: First, install the pressure transmitter with a filtering structure at a designated position. The water flow enters the inside of the installation pipe 1. The smaller particles and impurities in the water flow are filtered by the small filter screen 24 inside the installation pipe 1, and then the larger particles in the water flow are filtered by the large filter screen 22. Since the large filter screen 22 and the small filter screen 24 are in a barrel structure, the filtering capacity can be increased, avoiding the problem of reduced flow rate and improving the practicability of the pressure transmitter with a filtering structure. The water flow enters the inside of the connecting pipe 4 through the installation pipe 1. The pressure transmitter main body 42 is supported through the mounting base 41 and sensed through the sensor 43, and then detected through the pressure transmitter main body 42. When it is necessary to clean the small filter screen 24 and the large filter screen 22, close the two control valves 11 on both sides in the middle of the installation pipe 1 and open the two switching valves 15 on both sides of the side pipe 14, so that the water flow can pass through the inside of the side pipe 14, bypassing the position of the connecting groove 12 and avoiding the water flow from entering the connecting groove 12. By rotating, remove the four mounting bolts 34, and by lifting the handle 32 upward, the insertion block 2 can be driven to move upward, driving the large filter screen 22 inside the mounting plate 21 and the small filter screen 24 inside the connecting ring 23 to move upward, so that the small filter screen 24 and the large filter screen 22 can be taken out for cleaning, improving the practicability and convenience of the pressure transmitter with a filtering structure. When the cleaning is completed, insert the insertion block 2 into the inside of the connecting groove 12. The sealing block 3 can fill and seal the inside of the connecting groove 12 and the gaps between the cover plate 31 and the connecting plate 13. By rotating the four mounting bolts 34, the cover plate 31 can be installed and fixed. Open the two control valves 11 and close the two switching valves 15 to make the water flow pass through the filter screen for filtering, improving the practicability and convenience of the pressure transmitter with a filtering structure.
