Abstract
The utility model relates to a constant pressure structure of a booster pump. A control rod drives a control rod to make reciprocating movement under the common action of a pressure limiting spring and water pressure in a pressure limiting water cavity to form a control assembly for controlling water flow between a water inlet and a lower pressure cavity to convert between flowing and non-flowing states. When the output water pressure of the booster pump is close to or reaches a design value, the control rod is pushed to move downwards, so that a water sealing membrane attached to the control rod is close to a sealing water seal port, and the output water pressure is reduced; when the output water pressure is lower than the design value, the acting force of the pressure limiting spring on a water inlet pressure-sensing membrane overcomes the acting force of water pressure in the pressure limiting water cavity on the pressure limiting membrane so as to push the control rod to move upwards, so that the water sealing membrane attached to the control rod is far away from the water seal port to keep the connection of waterways. Accordingly, the cycle is repeated, so that the output water pressure of the booster pump can be largely limited within the set values, and the product safety failure caused by reverse osmosis water purification equipment due to too high water pressure can be prevented.
