| titleOfInvention | Hydrostatic testing machine for steel cylinder of prestressed concrete cylinder pipe |
| abstract | The utility model discloses a hydrostatic testing machine for a steel cylinder of a prestressed concrete cylinder pipe. The hydrostatic testing machine comprises a rack and an annular pressure test liner; the axial direction of the pressure test liner and the rack are relatively fixed; a water inlet pipe is arranged in the pressure test liner; a water outlet of the water inlet pipe is formed in the outer surface of the lower side of the pressure test liner; an emptying channel is formed in the upper part of the pressure test liner; socket slot rings matched with the inside diameter of a steel cylinder to be detected are arranged at two ends of the pressure test liner; the socket slot rings and the pressure test liner are coaxially arranged; V-shaped rubber rings and rectangular rubber rings of the socket slot rings are sequentially arranged in a ring slot from inside to outside; an air inlet channel is arranged on the inner side of the ring slot. The to-be-tested steel cylinder is arranged on the pressure test liner in a sleeving manner and aerates towards the inside of the ring slot when the hydrostatic testing machine is used; the V-shaped rubber rings and the rectangular rubber rings are pushed out to seal the inner wall of the steel cylinder; the V-shaped rubber rings deform by pressure to seal the ring slot; water is injected into an annular space between the steel cylinder and the pressure test liner; whether the concrete pipe accords with the design requirements or not can be checked. Therefore, the hydrostatic testing machine is convenient to operate, easy to seal and quick in detecting. |
