Summary of the invention
The utility model technical matters to be solved is: a kind of difficult leakage, good sealing effect, easy to loading and unloading, steel cylinder outside measurement method water test unit that reliability is high are provided.
For solving the problems of the technologies described above; The technical scheme of the utility model is: steel cylinder outside measurement method water test unit; The water jacket that comprises the vertical setting that is used to hold steel cylinder; And the water jacket plug that is installed on said water jacket upper end, said water jacket plug comprises the water jacket lid, the hollow lid of said water jacket lid for being surrounded by upper plate body, lower body and side plate body; On the said water jacket lid forcing pipe that runs through and stretch out said upper plate body and lower body is installed, the upper end of said forcing pipe is connected with high-voltage quick joint, and the lower end of said forcing pipe is equipped with and is used for the bottleneck joint that is connected with the bottleneck of steel cylinder; Terminal pad also is installed on the said forcing pipe, is provided with the O RunddichtringO between the upper surface of said terminal pad and the lower surface of said lower body, be provided with y-type seal ring between said terminal pad and the said forcing pipe.
As preferably, on the said bottleneck joint bottleneck sealing gasket is installed.
As preferably, also be provided with suspension hook on the said upper plate body.
Owing to adopted technique scheme, the beneficial effect of the utility model is: when utilizing the test unit of the utility model that steel cylinder is carried out the hydraulic testing, will be tried steel cylinder and place in the water jacket; Utilize high-pressure hydraulic pump to pass through high-voltage quick joint and forcing pipe, in steel cylinder, inject water under high pressure, carried out supercharging trying steel cylinder; Automatically get into packing state after reaching set pressure, carried out withstand voltage test to trying steel cylinder, steel cylinder bodily form under the effect of water under high pressure expands; Be expressed to a part of water in the water jacket in the outside measuring cup that is communicated with it and go; This part water yield is tried the volume all deformation of steel cylinder, transfers in the industrial computer through water yield acquisition system, after the steel cylinder release; Elastic deformation disappears; So the water in the measuring cup turns back in the water jacket again, but the remaining water yield is still than many before the steel cylinder pressurization in the measuring cup, and this additional water yield is tried the permanent volumetric expansion amount of steel cylinder; Transfer in the industrial computer through water yield acquisition system, the ratio of permanent volumetric expansion amount and all deformation is exactly the rate of residual volumetric deformation of steel cylinder.Because the test unit of the utility model is provided with the O RunddichtringO between the lower surface of the upper surface of terminal pad and lower body, between terminal pad and forcing pipe, also be provided with y-type seal ring, thereby the package unit good sealing effect, is difficult for leaking the reliability height; When needs are changed O-ring seal, only need terminal pad is dismantled on lower body down, promptly replaceable, loading and unloading and easy to maintenance.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Accompanying drawing is the structure cross-sectional schematic of the utility model embodiment;
Among the figure: the 1-water jacket plug; The 11-upper plate body; The 12-lower body; The 13-terminal pad; The 14-suspension hook; The 2-water jacket; The 3-steel cylinder; The 4-forcing pipe; The 5-high-voltage quick joint; The 6-Y RunddichtringO; The 7-O RunddichtringO; 8-bottleneck joint; 9-bottleneck sealing gasket.
Embodiment
Shown in accompanying drawing; Steel cylinder outside measurement method water test unit; The water jacket 2 that comprises the vertical setting that is used to hold steel cylinder 3; And the water jacket plug 1 that is installed on said water jacket 2 upper ends, said water jacket plug 1 comprises the water jacket lid, the hollow lid of said water jacket lid for being surrounded by upper plate body 11, lower body 12 and side plate body; The forcing pipe 4 that runs through and stretch out said upper plate body 11 and lower body 12 is installed on the said water jacket lid, and the upper end of said forcing pipe 4 is connected with high-voltage quick joint 5, and the lower end of said forcing pipe 4 is equipped with and is used for the bottleneck joint 8 that is connected with the bottleneck of steel cylinder 3; On the said forcing pipe 4 terminal pad 13 is installed also; Be provided with O RunddichtringO 7 between the lower surface of the upper surface of said terminal pad 13 and said lower body 12; Bolt is connected between the disk body of said terminal pad 13 and the lower body 12, is provided with y-type seal ring 6 between the dish hub of said terminal pad 13 and the said forcing pipe 4.
