[0025] This utility model provides two technical solutions: Figures 1 to 2 A first embodiment is shown: a Venturi valve control box device, comprising:

[0026] Base 1, used for mounting actuators and transformers;

[0027] Mounting plate 2 is symmetrically fixed on the front and rear sides above the base 1;

[0028] C-shaped bracket 3 is symmetrically installed on the left and right sides above the base 1 by the first bolt. C-shaped bracket 3 is used to install sensors and controllers.

[0029] The top cover 5 is a detachable cover installed above the base 1. The top cover 5 is bent into shape corresponding to the positions of the two C-shaped brackets 3.

[0030] A moisture-absorbing component is installed on top of the upper cover 5. When the upper cover 5 is placed on top of the base 1, the moisture-absorbing component absorbs the moisture in the cavity formed by the base 1 and the upper cover 5.

[0031] Four slots 6 are provided on the top of the base 1. The four slots 6 are arranged symmetrically. Four plates 7 are fixed at the bottom of the top cover 5 corresponding to the slots 6. The plates 7 are slidably connected to the inner wall of the slots 6.

[0032] Both mounting plates 2 have a first threaded hole 8 on their tops, and the top cover 5 has a second threaded hole 9 at both ends corresponding to the first threaded hole 8. The inner walls of the first threaded hole 8 and the second threaded hole 9 are connected by a second bolt through a thread to fix the top cover 5 above the base 1.

[0033] This application improves space utilization, reduces the overall volume and weight of the control box by adopting an internal double-layer compact structure; the box body is changed to two pieces for snap-fit ​​fixation, and is transparent on three sides, making it easy to disassemble and maintain, and reducing safety risks.

[0034] Figures 3 to 4 The second embodiment is shown. The main difference from the first embodiment is that the moisture-absorbing component includes a through hole 10 on the top of the top cover 5. A housing 18 is fixed on the top of the top cover 5 around the through hole 10. A flip cover 11 is rotatably connected to the top of the housing 18 via a pivot pin. A clamping component for holding the moisture-absorbing bag is installed on the side of the flip cover 11 near the through hole 10. A snap-fit ​​component is installed on the top of the housing 18 to position the flip cover 11 above the housing 18 and prevent it from flipping.

[0035] The clamping assembly includes a rotating shaft 12 that is rotatably connected to the flip cover 11 near the through hole 10. A clamping plate 14 is fixed in the middle of the rotating shaft 12, and torsion springs 13 are fixed at both ends of the rotating shaft 12. The end of the torsion spring 13 away from the clamping plate 14 is fixed to the flip cover 11.

[0036] The snap-fit ​​assembly includes a housing 15 fixed to the top of the outer casing 18. A snap-fit ​​block 16 is slidably connected to the inner wall of the housing 15. The bottom of the snap-fit ​​block 16 is movably connected to the flip cover 11. A pull block 4 is fixed to the side of the snap-fit ​​block 16 away from the flip cover 11. The end of the pull block 4 away from the snap-fit ​​block 16 is slidably connected to the housing 15 and forms a bend. Elastic springs 17 are symmetrically fixed to the inner wall of the housing 15. The end of the elastic spring 17 away from the housing 15 is fixed to the snap-fit ​​block 16.

[0037] This application effectively solves the problem of electrical component damage caused by moisture inside the control box by setting up a moisture-absorbing component. By absorbing moisture in the chamber, the moisture-absorbing bag ensures that the internal environment of the control box is dry and extends the service life of the electrical components.

[0038] Working principle:

[0039] The first and second bolts are existing technologies and will not be described in detail.

[0040] Install the actuator and transformer on the base 1, install the C-type bracket 3 symmetrically on the base 1 with the first bolt, install the controller and sensor on the two C-type brackets 3 respectively, and then connect the control lines; then fix the base 1 in the designated position of the valve body; insert the card plate 7 of the upper cover 5 into the corresponding slot 6, and then use the second bolt to pass through the first threaded hole 8 and the second threaded hole 9 to fix the upper cover 5 on the base 1.

[0041] Pull the pull block 4 away from the flip cover 11, so that the locking block 16 enters the housing 15. The spring spring 17 is compressed, releasing the limit on the flip cover 11, allowing the flip cover 11 to flip open. Pull the clamping plate 14, so that the clamping plate 14 clamps the moisture-absorbing bag on one side of the flip cover 11 under the action of the torsion spring 13. Then close the flip cover 11. The flip cover 11 presses the inclined surface of the locking block 16, so that the locking block 16 re-enters the housing 15 until the flip cover 11 flips to below the locking block 16. The locking block 16 pops out under the action of the spring spring 17 and positions the flip cover 11. The moisture-absorbing bag absorbs the moisture in the cavity formed between the upper cover 5 and the base 1 through the through hole 10.
