Document Type and Number:
Japanese Patent JP2023175185
Kind Code:
A
Abstract:
To provide a test device which can easily perform a breakage confirmation test of a fire hose.SOLUTION: A test device comprises a channel selector valve 2 and a cap 4. The channel selector valve 2 comprises: a valve box 20 which includes therein, an inflow path 21, a first outflow path 22 and a second outflow path 23; a valve body 100 which can close any one of the first outflow path 22 and the second outflow path 23; and a spring 80 which can make the valve body 100 close the second outflow path 23 with biasing force along a central shaft of the second outflow path 23. The cap 4 arranges the valve body 100 at a position of closing the first outflow path 22 by moving the valve body 100 in a direction of being apart from the second outflow path 23 against the biasing force of the spring 80 when being coupled to a secondary side of the second outflow path 23. The cap 4 has the coupling force that may withstand a pneumatic pressure injected to the fire hose in order to confirm whether the fire hose is broken, and fixes the valve body 100 at the position of closing the first outflow path 22 against the pneumatic pressure.SELECTED DRAWING: Figure 6
