End test water detector

The utility model discloses an end test water detector, comprising a valve, a flux manometer and a connection pipe. The essential structure is that the device also comprises four-through valve (4), and a valve (1) is arranged at the water inlet end of the connection pipe (3), the four-through valve is connected with the water outlet end of the connection pipe (3), and the flux manometer (2) is arranged on the connection pipe (3) in the back of the valve (1). The four-through valve (4) comprises a valve body (6) and a valve core (5) which are mutually matched, a guide hole (9) which is communicated with a hole (8) on the valve body is arranged in the transversal direction of the valve core (5) which is arranged on the middle of the valve body (6). The end test water detector overcomes the defects existing the prior art, can conveniently regulate the testing state, the flux of a detection system and kinetic pressure, static pressure, pressure switch and the movements of a water flow indicator.
