Embodiment
Further specify referring to figs. 1 through 7 couples of embodiment of the present utility model:
Embodiment:
The utility model is comprised of water filling end pressure text head 1, water filling end O-ring seal 2, hydraulic open-close clamping device 3, pressure testing bend pipe 4, balance device 5, exhaust end O-ring seal 6, exhaust end pressure text head 7, camber line track 8, exhausr port 9, hydraulic cylinder 10, pressure testing platform 11, rectilinear orbit 12, water filling port 13 and circular ring type clamping device 15 etc.:
Pressure testing bend pipe 4 one end pipe faces are connected with the water filling end pressure text head 1 of water filling port 13; water filling end pressure text head 1 connects water filling end O-ring seal 2 and is located on the rectilinear orbit 12; be provided with the hydraulic open-close clamping device 3 of two lobe circular arc types near the bend pipe pipe face of water filling end; its clamping surface is inlaid with rubber cover 14; outside surface connecting fluid cylinder pressure 10, both all by bolted splice on pressure testing platform 11.Pressure testing bend pipe 4 other end pipe faces are connected with the exhaust end pressure text head 7 of exhausr port 9, and exhaust end pressure text head 7 connects exhaust end O-ring seal 6 and is located on the camber line track 8, and the bend pipe pipe face of close exhaust end is provided with circular ring type clamping device 15.Pressure testing bend pipe 4 middle parts are fixing by balance device 5, and balance device 5 is fixed on the pressure testing platform 11 by bolt 16, and its sidepiece fixedly is inlaid with rubber layer 17 on the cambered surface, and fixedly cambered surface and bend pipe pipe face fit tightly.
Balance device 5 is used for firm pressure testing bend pipe 4, cushion outer acting force, protects bend pipe not to be damaged, its fixedly cambered surface can adapt to the different conditions of bend pipe, maintenance contacts with the best of bend pipe.Rectilinear orbit 12 and arc track 8 are used for moving horizontally with camber line of pressure text head of realization and move, to satisfy the pressure testing requirement of different angles and different length bend pipe.
Installation of the present utility model and pressure testing process are as follows:
To treat that pressure testing bend pipe 4 places on the pressure testing platform 11 of horizontal positioned, fit tightly the pipe face of hydraulic open-close clamping device 3 and pressure testing bend pipe 4 fixing.Angle according to pressure testing bend pipe 4, regulate water filling end pressure text head 1 in the position on the rectilinear orbit 12 and the position of exhaust end pressure text head 7 on camber line track 8, make water filling end O-ring seal 2 and exhaust end O-ring seal 6 seal reliably pipe end, guarantee that the fixedly cambered surface of pressure testing bend pipe 4 pipe faces and balance device 5 fits tightly.
