Technical Field

[0001] The utility model relates to the technical field of pressure transmitters, in particular to an adjustable pressure transmitter. Background Art

[0002] At present, pressure transmitter is a device that converts pressure into pneumatic or electric signals for control and remote transmission. 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 indicator alarms, recorders, regulators, etc. for measurement, indication and process regulation.

[0003] There are many existing technologies for adjustable pressure transmitters, such as:

By arranging the mounting tube, the transmitter body, the mounting plate, the through hole, the card slot, the conversion plate, the adjustment hole and the connector, it is achieved that a connector matching the pipe to be connected is first selected, the conversion plate is moved along the card slot to drive the connector to connect with the through hole, and then the connector is connected to the connecting pipe. The flow out of the connecting pipe will flow along the connector, the conversion hole, the through hole and the mounting tube in turn. The transmitter body can detect the flow in the mounting tube, and by switching different connectors to match pipes of different sizes, the working limitations are reduced, the versatility is high, and the convenience of use is improved.

[0005] It can be seen that most pressure transmitters are installed by moving the position of the mounting plate and adjusting connectors of different sizes.

[0027] Most pressure transmitters are installed by moving the position of the mounting plate and adjusting connectors of different sizes. However, during the replacement process, it is inevitable to spend some time aligning the position of the connector, which not only reduces the efficiency of the pressure transmitter adjustment and wastes time, but also reduces the sealing of the connection between the mounting plate and the connector, affecting the data detected by the pressure transmitter. In severe cases, it will increase the frequency of failure of the pressure transmitter, thereby reducing the service life of the pressure transmitter.

[0028] See also Figure 1-Figure 5 The embodiment of the utility model shown in the figure comprises a mounting plate 10, a connecting plate 20 and a pressure transmitter body 22. A plurality of auxiliary components 11 are arranged inside the mounting plate 10, and connectors 12 of different sizes are arranged inside the plurality of auxiliary components 11. The plurality of auxiliary components 11 are used to assist the connectors 12 in installation. The connector 12 passes through one side of the mounting plate 10 and a filter screen 13 is arranged inside the connector. A connecting pipe 21 for installing the pressure transmitter body 22 is arranged on one side of the connecting plate 20, and one side of the connecting pipe 21 passes through the connecting plate 20 and is threadedly connected to the connector 12. The connecting plate 20 is plugged in close to the mounting plate 10 through a positioning component 23, and a fixing component 30 for stabilizing the position of the connecting plate 20 is arranged on the upper and lower surfaces of the connecting plate 20.

[0029] First, the specific structure of the auxiliary component 11 is disclosed. The auxiliary component 11 at least includes a mounting groove 111. A plurality of mounting grooves 111 are opened inside the mounting plate 10. A gear 112 is provided on the surface of the connector 12 located inside the mounting groove 111. The gear 112 is meshingly connected with a rack 113. A handle 114 is provided on one side of the rack 113 close to the opening of the mounting plate 10.

[0030] The improvement lies in that: by pulling the handle 114, the rack 113 drives the gear 112 to rotate, and drives the connecting head 12 to be threadedly connected with the connecting pipe 21. This is not only simple to operate, but also improves the stability of the installation of the pressure transmitter body 22, improves the work efficiency of the installation of the pressure transmitter body 22, reduces the frequency of failure of the pressure transmitter body 22, and thus increases the service life of the pressure transmitter.

[0031] Secondly, the specific structure of the positioning component 23 is disclosed. The positioning component 23 at least includes a positioning block 231 and a positioning groove 232. The positioning groove 232 is provided on the side of the connecting plate 20 away from the pressure transmitter body 22, and the side of the mounting plate 10 away from the connector 12 is provided with a positioning block 231 for plugging with the positioning groove 232. The positioning block 231 is made of elastic material.

[0032] The improvement lies in that: when the connecting plate 20 is moved, the positioning block 231 is in an arc shape on one side close to the connecting plate 20, so that the connecting plate 20 can squeeze the positioning block 231, causing it to deform and shrink, and enter the interior of the mounting plate 10. When the positioning block 231 encounters the positioning groove 232, the resilience of the positioning block 231 enables it to be plugged into the positioning groove 232, which not only increases the stability of the position of the connecting plate 20, but also allows the connection plate 20 to be known to the specified position more quickly, thereby improving the work efficiency of the pressure transmitter body 22 in replacing the connector 12, avoiding time waste, and also improving the accuracy of the pressure transmitter body 22 for different water flow detection data, thereby improving the effect of the pressure transmitter.

[0033] The specific structure of the fixing assembly 30 is disclosed again. The fixing assembly 30 at least includes a fixing plate 31. The fixing plates 31 are arranged above and below the connecting plate 20. The side of the lower surface of the fixing plate 31 away from the connecting plate 20 is slidably connected to a clamping plate 33 through a limiting assembly 32. A stabilizing plate 34 is arranged on the side of the fixing plate 31 close to the clamping plate 33. A threaded column 35 is threadedly connected to one side of the stabilizing plate 34. The threaded column 35 penetrates the stabilizing plate 34 and approaches the clamping plate 33.

[0034] The improvement lies in that: by rotating the threaded column 35 clockwise, the limit assembly 32 can slide, and the pressure on the clamping plate 33 can be released. At this time, the clamping plate 33 is pushed away from the mounting plate 10, and the connecting plate 20 can be moved to replace the connecting head 12 of different sizes. Then, by rotating the threaded column 35 counterclockwise to apply pressure to the clamping plate 33, it can clamp the mounting plate 10, and the position of the connecting plate 20 can be stabilized. Not only is the operation simple and the disassembly convenience is improved, but also the flexibility of the use of the pressure transmitter body 22 is improved, thereby improving the practicability of the installation of the pressure transmitter body 22.

[0035] Then, the specific structure of the limit assembly 32 is disclosed. The limit assembly 32 at least includes a limit groove 321 and a limit block 322. The limit groove 321 is provided on one side of the lower surface of the fixed plate 31 close to the stabilizing plate 34, and the upper surface of the clamping plate 33 is provided with a limit block 322 for sliding connection with the limit groove 321.

[0036] The improvement lies in that when the threaded column 35 is rotated, the limit block 322 slides inside the limit groove 321, which not only increases the stability of the movement of the clamping plate 33, but also improves the efficiency of fixing the position of the connecting plate 20, thereby improving the safety of replacing the connecting head 12 of the pressure transmitter body 22.

[0037] When the locking cam 33 is in the locked state, the locking cam 33 is in the locked state, and the locking cam 33 is in the locked state.
