Description

Technical Field

[0001] The utility model relates to the technical field of pump pressure regulation, in particular to a fountain pump pressure regulating device. Background Art

[0002] To beautify the environment, people have installed fountains in various places, such as squares, homes, and hotels, creating a natural-looking environment from a static one. The power source for these fountains comes from a fountain pump. A fountain pump typically consists of a housing, a motor, and an impeller. The housing is equipped with a water inlet and outlet. The motor turns the impeller, driving water in through the inlet and out through the outlet. The water flows through a hollow channel within the pump body.

[0003] Usually, valves and nozzles are set at the water outlet of the fountain pump to control the water outlet pressure through the valve. This control method has a high failure rate and lacks effective protection at high pressure, which can easily cause damage to the fountain pump due to high pressure. Utility Model Content

[0004] In order to overcome the defect in the prior art that equipment is damaged due to unstable pressure, the utility model provides a fountain pump pressure regulating device.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a fountain pump pressure regulating device, including a pump body, a flow guide cover is provided on the outer wall of the pump body, the pump body and the flow guide cover are connected by threads, the lower part of the flow guide cover is provided with a sealing ring that can divide the inner cavity of the flow guide cover into an outer valve cavity and an inner valve cavity, the inner valve cavity is provided with a pressure guide ring, the top of the pressure guide ring is provided with a plurality of pressure guide holes, the pressure guide ring is arranged on the outside of the pump body, the water suction end of the pump body is connected to a sealing piston that can cooperate with the sealing ring through a straight pipe, and the side of the straight pipe is provided with a plurality of pipe openings.

[0006] As a further improvement of the present invention, a filter screen is provided in the outer valve cavity to filter impurities in the water.

[0007] As a further improvement of the present invention, a rubber gasket is provided between the flow guide cover and the pump body to prevent leakage.

[0008] As a further improvement of the present invention, a rotating handle is provided on the outer wall of the top of the pump body to improve working efficiency.

[0009] As a further improvement of the present invention, a spray head is provided at the water outlet end of the pump body to improve the water spraying effect.

[0010] As a further improvement of the present invention, a pressure digital display is provided on the pipeline of the nozzle to display the water pressure in real time.

[0011] Compared with the prior art, the utility model has the following beneficial effects: in this solution, the pump body performs a spiral upward or downward motion on the guide cover, thereby adjusting the distance between the sealing piston and the sealing ring at the end of the straight pipe, and then adjusting the water flow entering the inner valve cavity to complete the pressure regulation. The gap between the pressure guide ring and the guide cover forms a pressure guide cavity. A plurality of pressure guide holes are provided on the top of the pressure guide ring. The water flows through the pressure guide cavity through the pressure guide holes and circulates to the bottom of the pressure guide ring. The pressure guide ring plays a pressure guiding role. The pressure guide ring compresses the expansion range of the water flow beam, making the flow field in the inner valve cavity more uniform, so that the water is fully filled in the inside of the device to maintain stable pressure.

[0015] In order to make the technical solution and beneficial effects of the present invention more clearly understood, the present invention will be further described in detail below with reference to specific embodiments.

[0016] Reference Figure 1 The embodiment of the utility model discloses a fountain pump pressure regulating device, including a pump body 1, a flow guide cover 2 is provided on the outer wall of the pump body 1, the pump body 1 and the flow guide cover 2 are connected by threads, and the lower part of the flow guide cover 2 is provided with a sealing ring 4 that can divide the inner cavity of the flow guide cover 2 into an outer valve cavity 5 and an inner valve cavity 6, a pressure guide ring 7 is provided in the inner valve cavity 6, and a plurality of pressure guide holes 8 are provided on the top of the pressure guide ring 7. The pressure guide ring 7 is arranged on the outside of the pump body 1, and the water suction end of the pump body 1 is connected to a sealing piston 10 that can cooperate with the sealing ring 4 through a straight pipe 9, and a plurality of pipe openings 11 are provided on the side of the straight pipe 9.

[0017] Among them, a filter screen cover 3 is provided in the outer valve chamber 5, and the water flows into the guide cover 2 through the filter screen cover 3. The guide cover 2 can effectively filter impurities in the water, making the water flow flowing from the filter screen cover 3 to the guide cover 2 more stable, thereby maintaining the stability of the pressure in the pump body 1.

[0018] Start the pump body 1, and the pump body 1 extracts water from the inner valve cavity 6 in the deflector 2 through the straight pipe 9. The external thread on the pump body 1 is threadedly connected with the internal thread in the deflector 2. A rotating handle 13 is provided on the outer wall of the top of the pump body 1. By rotating the handle 13, the pump body 1 is rotated, which saves time and effort and improves work efficiency.

[0019] Rotate the pump body 1, and the pump body 1 makes a spiral upward or downward motion on the guide cover 2, thereby adjusting the distance between the sealing piston 10 at the end of the straight pipe 9 and the sealing ring 4, and then adjusting the water flow entering the inner valve chamber 6 to complete the pressure regulation. The operation method is relatively convenient. The gap between the pressure guide ring 7 and the guide cover 2 forms a pressure guide chamber. A plurality of pressure guide holes 8 are provided on the top of the pressure guide ring 7. The water flows through the pressure guide hole 8 through the pressure guide chamber and circulates to the bottom of the pressure guide ring 7. The pressure guide ring 7 plays a pressure guiding role. The pressure guide ring 7 compresses the expansion range of the water flow beam, making the flow field in the inner valve chamber 6 more uniform, so that the water is fully filled in the inside of the device, so that the water pressure in each part of the device is the same, and the pressure is kept stable.

[0020] A rubber gasket 12 is provided between the deflector cover 2 and the pump body 1. The rubber gasket 12 plays a sealing role. When the pump body 1 spirally rises or falls on the deflector cover 2, the rubber gasket 12 can seal the gap at the connection between the pump body 1 and the deflector cover 2 to prevent leakage.

[0021] The water outlet of the pump body 1 is provided with a nozzle 14, and a pressure digital display 15 is provided on the pipeline of the nozzle 14 to improve the water spraying effect. Different nozzles can be installed according to needs. The pressure digital display 15 displays the water pressure in real time to improve the monitoring effect.
