The invention relates to a sanitary-ware valve-switch-a device for nozzle performance testing. The single-handle double-control nozzle service life testing device comprises a vertical test-bed rack (1). The tested nozzle (G) is fixed in the middle of the rack (1), and is connected with the hot-water and cold-water inlet pipe (9); a lifting component which can move upward and downward is arranged above the rack (1), and the lifting component comprises a numerical-control electric motor (8) coupled with a lead-screw pair; the lifting device is arranged on the rotary disc (5) driven by a small numerical-control electric motor (6); and the two ends of a long connecting-rod (4) are connected with the nut and the grip block of the lead-screw pair by horizontal shaft pins (11, 12). The movement of the numerical-control electric motor (8) reduces and avoids the impact to the handle of the tested nozzle (G) and as well as the damage incurred thereto; the test result of the actual object is moreobjective and accurate, the test scope can cover a spherical surface larger than 180 degrees, and the test can be conducted under a comprehensive, accurate, precise and more real condition, and the automatic degree of the test is relatively high.
