Problems solved by technology
[0004] When the existing booster pump stops working, the internal pressure disappears, and the water flow will flow backwards. When it is used next time, it is necessary to add water to the inside of the pipeline to fill the inside of the pump with water, which makes the work time-consuming and laborious;

Abstract
The invention relates to the field of water pumps, in particular to a pressurized anti-reflux water pump which comprises a shell, a water inlet pipe is fixedly mounted in the middle of the left side of the shell, a water outlet pipe is fixedly mounted on the upper portion of the rear end of the shell, a driving motor is fixedly mounted on the right side of the shell, and a driving shaft is movably mounted on the left side of the driving motor; the outer side of the driving shaft is fixedly sleeved with a power mechanism, a transmission connecting rod set is movably installed at the lower end of the power mechanism, and a sealing mechanism is movably installed on the left side of the transmission connecting rod set. The power mechanism comprises a rotating base, the rotating base is fixedly connected to the outer surface of the driving shaft in a sleeving mode, sliding grooves are evenly formed in the side, close to the driving motor, of the rotating base, first return springs are fixedly installed at the ends, away from the driving shaft, of the sliding grooves, and the power mechanism does not need to be additionally provided with an external circuit. Meanwhile, the sealing mechanism cannot block water flow when the water pump works, can ensure that the water flow is in the maximum state, and prevents water from flowing back for use next time when the water pump stops working.
Description
technical field [0001] The invention relates to the field of water pumps, in particular to a pressurized anti-backflow type water pump. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid, and is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal; [0003] Liquids, gas mixtures and liquids containing suspended solids can also be transported. The technical parameters of pump performance include flow rate, suction lift, lift, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into volumetric pumps, vane pumps and other types. Positive displacement pumps use the volume change of their working chambers to transfer energy; vane pumps use the interaction between rotating blades and water to transfer...
