Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, and particularly relates to a fully disassembled and repaired pressure controller. Background Art

[0002] A water pump is a mechanical device used to transport liquids or increase the pressure of liquids. During the use of a water pump, a pressure controller is usually required to monitor the working state of the water pump and control the start and stop of the water pump and the pressure value in real time, so as to achieve the effects of protecting the normal operation of the water pump, controlling the water pressure, and saving energy and reducing emissions.

[0003] Existing technologies such as the utility model with the publication number of CN220748508U disclose a water pump pressure controller, which includes a middle body with a water inlet and a water outlet. A cavity is arranged between the water inlet and the water outlet in the middle body. The water pump pressure controller further includes a sealing member, a reading device, a pressure sensor with a power connector at the end, and a base with a cavity. The base is detachably connected to the middle body. The middle body is provided with an installation hole communicating with the cavity, and a through hole for the power connector to extend into is arranged on the cavity. The pressure sensor is clamped on the installation hole, the sensing end of the pressure sensor is located in the cavity, the power connector of the pressure sensor extends into the through hole, the sealing member is used for sealing the connection between the pressure sensor and the through hole or the installation hole, and the reading device is used for feeding back the value measured by the pressure sensor to the user. By detecting the pressure inside the cavity through the pressure sensor and reading and feeding back the measured value by the reading device, it can help the user better understand the real-time pressure inside the water pump and perform maintenance and adjustment on the water pump in time.

[0004] The above-mentioned and existing related technologies often have the following defects: during the process of using the pressure controller to monitor and control the working state of the water pump, it is often difficult to avoid the situation that the pressure controller fails to operate.

A second spring 53 is fixedly connected to the side of the rotating plate 52 away from the push plate 410, and the other end of the second spring 53 is fixedly connected to the "L"-shaped plate 51.

[0038] Working principle: When assembling the upper housing 2 and the lower housing 1, first grasp the collar 402 and rotate the screw 404 to make it rotate inside the inner wall of the arc-shaped plate 403, thereby controlling the collar 402 to move away from the fixed plate 401. Then push the circular plate 407, so that the control rod 406 slides inside the inner wall of the first connecting plate 405, controlling the push plate 410 and the limiting rod 411 to move away from the first connecting plate 405. Then move the lower housing 1 closer to the upper housing 2 and release the circular plate 407. Under the action of the elastic force of the first spring 408, the limiting rod 411 moves closer to the second connecting plate 409 to fix the upper housing 2 and the lower housing 1. Then rotate the screw 404 to make the collar 402 move closer to the upper housing 2 and the lower housing 1 to complete the connection between the upper housing 2 and the lower housing 1. By providing the sealing plate 412, the sealing performance of the connection between the upper housing 2 and the lower housing 1 can be improved. By providing the pressure gauge 3, the water pump pressure can be monitored in real time. By providing the connecting device 4, when it is necessary to repair the water pump pressure controller, the water pump pressure controller can be conveniently disassembled completely, so that the maintenance personnel can conveniently repair and maintain its interior, improving the effect and convenience of repairing the pressure controller.

[0039] When assembling the upper housing 2 and the lower housing 1 of the pressure controller, first control the movement of the push plate 410 to approach the "L"-shaped plate 51, so that the push plate 410 pushes the rotating plate 52 to rotate. Continue to move the push plate 410. When the push plate 410 moves away from the rotating plate 52, under the action of the elastic force of the second spring 53, the rotating plate 52 rotates to approach the stop lever 54. After moving the upper housing 2 close to the lower housing 1, push the fixed block 55 to slide on the surface of the fixed rod 57, so that the push rod 56 pushes the stop lever 54 to move away from the rotating plate 52. Then move the push plate 410 away from the rotating plate 52. After fixing the positions of the upper housing 2 and the lower housing 1, release the fixed block 55. Under the action of the elastic force of the third spring 58, the stop lever 54 moves close to the rotating plate 52 to limit the position of the rotating plate 52. By providing the fixing device 5, when assembling the upper housing 2 and the lower housing 1, the positions of the connecting components can be restricted, thus facilitating the staff to assemble the pressure controller and reducing the complexity of assembling the pressure controller.
