Description

Technical Field

[0001] The utility model relates to the technical field of pressure control devices, and more particularly to a pressure control device for a horizontal flow pump. Background Art

[0002] A horizontal flow pump, also known as a mixed flow pump, is a pump that can produce a fluid horizontal flow state. It mainly produces rotation and flow inside the pump body through the rotation of the impeller, causing the fluid to rotate and flow axially in the inlet and outlet flow channels, thereby forming a uniform flow field along the axial motion, that is, a fluid horizontal flow state. The horizontal flow pump is mainly based on the impeller driving the fluid to rotate, and uses the energy generated by the rotation to promote the fluid flow. The horizontal flow pump has a wide range of applications in industrial production, water treatment, agricultural irrigation and other fields.

[0003] Deficiencies of the existing horizontal flow pump pressure control device: The main function of the horizontal flow pump pressure control device is to ensure that the horizontal flow pump operates stably according to the preset pressure value when conveying fluid. By adding a regulating valve at the pump head of the horizontal flow pump, and then adjusting the opening and closing degree of the valve to change the resistance in the pipeline, the output pressure is controlled. However, the regulating valve in the existing horizontal flow pump pressure control device needs to be adjusted manually when adjusting the pressure of the horizontal flow pump, and manual adjustment is often difficult to achieve the preset accuracy. In addition, the regulating parts of the regulating valve are in contact with the fluid for a long time, which will cause wear of the parts. The gap between the worn valve core and the pump body increases the sealing performance. Utility Model Content

[0006] Furthermore, a transmission motor is provided on one side of the pump body, a main shaft is fixedly connected to the other side of the transmission motor, an impeller is fixedly connected to the other side of the main shaft, a connecting pipe is fixedly connected to one side of the top of the outer surface of the pump body, and a flow port is opened in the middle of the water blocking component.

[0007] Furthermore, the outer surface of the round block is fixedly connected to a fixed block, the front of the fixed block is fixedly connected to a servo motor, the top of the servo motor is fixedly connected to a first gear, the outer surface of the first gear is movably connected to an outer ring tooth, the two sides of the outer surface of the outer ring tooth are movably connected to a second gear, and the bottom of the second gear is fixedly connected to an adjusting rod.

[0008] Furthermore, movable openings are provided on both sides of the movable block, an adjusting rod is movably connected to the inner surface of the movable opening, an outer thread is fixedly connected to the bottom of the outer surface of the mounting block, and an inner thread is provided on the inner surface of the valve core.

[0009] Furthermore, the surfaces of the movable block and the adjusting rod are both provided with threads and are adapted to each other.

[0010] Furthermore, threaded holes are provided on the inner surface of the valve core and the inner surface of the mounting block and are movably connected with bolts.

[0011] Furthermore, the outer surface of the round block is fixedly connected to a bearing, and the outer ring of the bearing is fixedly connected to outer ring teeth.

[0012] The technical effects and advantages of this utility model are:

[0013] 1. When the flow pressure of the horizontal flow pump needs to be adjusted, the servo motor is started to make the first gear start to rotate. When the first gear starts to rotate, the outer ring gear starts to rotate. When the outer ring gear rotates, the second gear on the surface starts to rotate. When the second gear starts to rotate, the adjusting rod starts to rotate. When the adjusting rod starts to rotate, it drives the movable block to move upward. When the movable block moves upward, the mounting block drives the valve core to move upward and separate from the flow port. The servo motor drive can make the valve core accurately adjust the flow of the horizontal flow pump when it moves. Compared with manual adjustment, automatic adjustment reduces the error caused by human factors and improves the adjustment accuracy of the system.

[0014] 2. When the valve core of the utility model needs to be replaced, the bolt is rotated to remove it from the valve core and the mounting block, and then the valve core is rotated to separate the outer thread and the inner thread so that the valve core can be quickly replaced. By quickly replacing the valve core, the worn parts can be replaced in time, avoiding more serious damage caused by long-term wear, thereby reducing the cost of repairing and replacing the entire valve.
