Beschreibung
Zusammenfassung:	A multifunctional visual precise pressure control apparatus special for running water and a pressure regulating method. The apparatus comprises a main body (1), and a pressure relief main body (2), a fine regulation main body (3) and a coarse regulation main body (4) which are arranged on the main body (1). The pressure relief main body (2) and the coarse regulation main body (4) are located at the upper portion of the main body (1). The fine regulation main body (3) is located at the lower portion of the main body (1). The pressure relief main body (2) is used for relieving the instantaneous change of the pressure in a pipe. The fine regulation main body (3) is used for precisely regulating water pressure fluctuation. The coarse regulation main body (4) is used for greatly regulating the water flow pressure. The apparatus has the functions of non-return, visualization and precise pressure control, thereby solving the problems of pipe explosion, water leakage and water pipe shaking in use due to the fact that
