Pressure stabilization structure having built-in integrally formed booster pump

Abstract

A pressure stabilization structure having a built-in integrally formed booster pump, comprising: a booster pump; a valve body, formed integrally with a shell of the booster pump, on the valve body is disposed a pressure release water input port and a pressure release water output port, a main valve core is disposed in an inner chamber of the valve body, that is movable to control the opening size of the pressure release water output port, and an auxiliary valve core is disposed in the inner chamber of the valve body, that is retractable to control the opening size of the pressure release water input port; a high pressure chamber, disposed on the booster pump, and is connected to the booster pump; and a low pressure chamber, disposed on the booster pump, and is connected to a the high pressure chamber through the valve body.

What is claimed is: 
     
         1 . A pressure stabilization structure having a built-in integrally formed booster pump, comprising:
 a booster pump;   a valve body, formed integrally with a shell of the booster pump, on the valve body is disposed a pressure release water input port and a pressure release water output port, a main valve core is disposed in an inner chamber of the valve body, that is movable to control the opening size of the pressure release water output port, and an auxiliary valve core is disposed in the inner chamber of the valve body, that is retractable to control the opening size of the pressure release water input port;   a high pressure chamber, disposed on the booster pump and is connected to a water output end of the booster pump, and is connected to the pressure release water input port disposed on the valve body; and   a low pressure chamber, disposed on the booster pump, and is connected to the high pressure chamber through the valve body, the low pressure chamber is connected to the pressure release water output port disposed on the valve body, and is connected to a water input end of the booster pump.   
     
     
         2 . The pressure stabilization structure having a built-in integrally formed booster pump as claimed in  claim 1 , wherein the main valve core includes a pipe piece, that is connected to the inner chamber of the valve body through threads, and an inner chamber of the pipe piece is a water flow channel; and a water input end of the pipe piece is disposed facing the auxiliary valve core, while a water output end of the pipe piece is disposed facing the pressure release water output port. 
     
     
         3 . The pressure stabilization structure having a built-in integrally formed booster pump as claimed in  claim 1 , wherein the auxiliary valve core includes:
 a spring; and   a piston, pressed and connected on the main valve core,   wherein one end of the spring is fixed in the inner chamber of the valve body, while one other end of the spring is fixed in a guiding slot of the piston.   
     
     
         4 . The pressure stabilization structure having a built-in integrally formed booster pump as claimed in  claim 3 , further comprising:
 a tight seal plate, disposed in a place where the piston is pressed and connected to the main valve core; and   two tight seal rings, disposed between the piston and the valve body, and between the main valve core and the valve body.
