[0002] A liquid level regulating valve, also known as a liquid level control valve or a liquid level regulating valve, is a valve specifically used to adjust the gravity level of a liquid container or the internal pressure of a container. This valve is usually composed of a stop valve, a throttle valve and a regulating mechanism. It can achieve rapid response and accurate control of the liquid level, keep the liquid level within a stable range, and prevent fluid overflow and excessive discharge.

[0003] During the use of the current liquid level regulating valve, after installation, the liquid level sensing position of the regulating valve is fixed, which makes it impossible for the staff to arbitrarily set or adjust the liquid level, making it impossible for the staff to adjust the liquid level regulating valve according to different working conditions. There are certain limitations in its use, which reduces the practicality of the liquid level regulating valve. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example

[0028] See also Figure 1-6 , the technical solution provided by this embodiment is as follows:

[0029] A liquid level regulating valve control device comprises a valve body 1, a control device 2 is installed on the top of the valve body 1, mounting frames 3 are bolted to the surfaces of the front and rear sides of the control device 2, a mounting box 4 is fixed between the mounting frames 3, a turning handle 5 is penetrated on the front side of the mounting box 4, a gear 6 is rotatably connected to the middle part of the inside of the mounting box 4, a first rack plate 7 and a second rack plate 9 are slidably connected to the left and right sides of the inner wall of the mounting box 4, a liquid level sensor 8 is fixed to the bottom of the first rack plate 7, and a stop structure 10 is fixed to the upper front side of the mounting box 4.

[0030] The rear end of the rotating handle 5 passes through the interior of the mounting box 4 and is fixedly connected to the front side of the gear 6, and the gear 6 is meshed with the first rack plate 7 and the second rack plate 9 respectively. The bottom of the mounting box 4 is open, and through grooves are provided on the left and right sides of the top of the mounting box 4. The first rack plate 7 and the second rack plate 9 are slidably connected to the inner wall of the through groove. The second rack plate 9 has the same length as the first rack plate 7, and the number of teeth on the surface of the second rack plate 9 and the first rack plate 7 is the same. When the staff rotates the rotating handle 5 on the front side, the gear 6 can be rotated. When the first rack plate 7 on one side moves up and down, the second rack plate 9 on the other side will move in the opposite direction. When the first rack plate 7 drops a certain distance, the second rack plate 9 will rise to a corresponding height.

[0031] A pointer 11 is fixed on the left side of the top of the installation box 4, and a scale line 12 is set on the surface of the right side of the second rack plate 9. When the second rack plate 9 moves up, the staff can accurately know the sensing position of the liquid level sensor 8 according to the pointing position of the pointer 11.

[0032] Limiting grooves 14 are provided on the left and right sides of the inner wall of the installation box 4, and limiting blocks 13 are fixed on the upper right side of the first rack plate 7 and the lower left side of the second rack plate 9, and the limiting blocks 13 are located inside the limiting grooves 14 and are slidably connected to the inner walls of the limiting grooves 14. When the gear 6 rotates, the first rack plates 7 and the second rack plates 9 on both sides move, and the limiting blocks 13 slide inside the limiting grooves 14, thereby limiting the first rack plates 7 and the second rack plates 9, so that the first rack plates 7 and the second rack plates 9 can only move in the up and down directions.

[0033] The stop structure 10 includes a mounting platform 101, an electric telescopic rod 102 and a stop plate 103. The mounting platform 101 is fixed above the front side of the mounting box 4, the electric telescopic rod 102 is installed at the bottom of the mounting platform 101, the stop plate 103 is fixed to the bottom end of the output shaft of the electric telescopic rod 102, and the stop plate 103 is slidably connected to the surface of the mounting box 4, the stop plate 103 is arranged in a semicircular arc shape as a whole, and a soft pad 15 is bonded to the surface below the stop plate 103, and the material of the soft pad 15 is wear-resistant rubber. When the staff completes the height adjustment of the liquid level sensor 8, the staff can open the upper electric telescopic rod 102, thereby lowering the stop plate 103, and positioning the turning handle 5 through the stop plate 103 to prevent the turning handle 5 from rotating. Through the setting of the soft pad 15, the positioning effect of the turning handle 5 can be improved to prevent the turning handle 5 from moving due to unexpected situations.

[0034] Working principle: When the liquid level regulating valve is in use, if the staff needs to adjust the liquid level sensing position, the staff first opens the electric telescopic rod 102 to move the stop plate 103 away from the top of the handle 5, and then the staff rotates the handle 5, thereby causing the first rack plate 7 on the right to drop, and adjust the height of the liquid level sensor 8, while the second rack plate 9 on the left also rises accordingly. When the staff rotates the handle 5, the staff can observe the scale line 12 on the surface of the second rack plate 9, and the descending height of the liquid level sensor 8 below can be known according to the rising height of the second rack plate 9. After the liquid level sensor 8 is accurately adjusted to the corresponding height, the staff stops rotating the handle 5, and then opens the electric telescopic rod 102 again, so that the stop plate 103 positions the handle 5, thereby completing the adjustment operation of the regulating valve.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
