[0024] The output end of the pressure difference sensor 4 is electrically connected to the input end of the PLC controller 7 , and the output end of the PLC controller 7 is electrically connected to the input ends of the indicator light 5 and the alarm 6 .

[0025] like Figure 1-5 As shown, the pressure gauge body 2 and the differential pressure sensor 4 are used to display pressure and pressure difference, which is convenient for the operator to observe the pressure difference change and make timely adjustments to avoid damage to the equipment, thereby ensuring the safe operation of the equipment and preventing unnecessary losses. The fixed plate 3 is used to support and fix the surface components. There are two indicator lights 5, one red and one green. Under normal conditions, the green light is on and the red light is off. When the differential pressure sensor 4 detects that the pressure difference exceeds the preset value of the PLC controller 7, the green indicator light 5 is off and the red indicator light 5 is on. At the same time, the alarm 6 is activated to alarm the operator so that he can take maintenance measures in time. By setting up a mounting frame 8 for installing the fixed plate 3 and setting up a mounting mechanism 9, it is convenient to install and disassemble the fixed plate 3 and the mounting frame 8 so that they can be regularly maintained and serviced.

[0026] Example 2

[0027] Reference Figure 2-4 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0028] In this embodiment, a slot 904 is provided at the top of the inner cavity of the mounting frame 8, and the inner cavity of the slot 904 is movably connected to a threaded rod 905 through a bearing. The threads on both sides of the surface of the threaded rod 905 are set in opposite directions, and both sides of the surface of the threaded rod 905 are threadedly connected to a threaded sleeve 906.

[0029] The bottom of the threaded sleeve 906 is fixedly connected to a positioning block 907, and both sides of the insert block 903 are fixedly connected to positioning sleeves 908. One side of the positioning block 907 extends to the inner cavity of the positioning sleeve 908 and is detachably connected to the inner cavity of the positioning sleeve 908.

[0030] like Figure 2-4 As shown, since the two adjacent mounting pieces 902 are connected by bolt threads, the mounting bracket 8 can be mounted on the surface of the circulating air thermostat body 1 by using bolts. When the threaded rod 905 rotates, since the threads on both sides of its surface are set in opposite directions, it can drive the two threaded rods 905 to move synchronously and in opposite directions on its surface. The threaded sleeve 906 can drive the positioning block 907 to move. After the positioning block 907 is inserted into the inner cavity of the positioning sleeve 908, it can be positioned to prevent the insert block 903 from falling off from the inner cavity of the slot 904, thereby achieving the purpose of installing the fixing plate 3.

[0031] Example 3

[0032] Reference Figure 4 and 5 , which is the third embodiment of the present utility model, is based on the first two embodiments.

[0033] In this embodiment, the right side of the mounting frame 8 is movably connected to a rotating handle 909 via a bearing. The left end of the rotating handle 909 passes through the inner cavity of the slot 904 and is fixedly connected to the right end of the threaded rod 905.

[0034] Limiting grooves 10 are provided on both sides of the top of the inner cavity of the slot 904. The top of the threaded sleeve 906 is fixedly connected to the limiting block 11. The top of the limiting block 11 extends to the inner cavity of the limiting groove 10 and is slidably connected to the inner cavity of the limiting groove 10.

[0035] like Figure 4 and 5 As shown, the rotating handle 909 facilitates the rotation of the threaded rod 905, and the limiting groove 10 and the limiting block 11 cooperate to limit the threaded sleeve 906 to prevent its angle from deflecting.

[0036] When in use, the pressure gauge body 2 and the pressure differential sensor 4 are used to display the pressure and pressure differential, which is convenient for the operator to observe the pressure differential change and make timely adjustments to avoid damaging the equipment, thereby ensuring the safe operation of the equipment and preventing unnecessary losses. There are two indicator lights 5, one red and one green. Under normal conditions, the green light is on and the red light is off. When the pressure differential sensor 4 detects that the pressure difference exceeds the preset value of the PLC controller 7, the green indicator light 5 is off and the red indicator light 5 is on. At the same time, the alarm 6 is activated to warn the operator, so that he can take maintenance measures in time. When disassembling and maintaining the components on the front of the fixed plate 3, first turn the rotating handle 909, which drives the threaded rod 905 to rotate. When the threaded rod 905 rotates, since the threads on both sides of its surface are set in opposite directions, it can drive the two threaded rods 905 to move synchronously and in opposite directions on its surface. The threaded sleeve 906 can drive the positioning block 907 to move, so that the positioning block 907 is removed from the inner cavity of the positioning sleeve 908. After it is removed, the entire fixed plate 3 can be removed to inspect the components on its surface. After the inspection is completed, the above operation can be reversed to reinstall it.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in this field. In addition, this application is mainly used to protect mechanical devices, so this application no longer explains the control method and circuit connection in detail.

[0038] While the present invention has been described above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations may be made without departing from the spirit and scope of the present invention.
