Description

Pipe adapter pull-out force testing machine
Technical field
The utility model relates to a kind of pipe adapter pull-out force testing machine, be mainly used in the anti-pull-out force performance of testing tube joint, be installed in pipe adapter on the traveling apparatus in particular for test, as be used for pipe adapter on automobile, train, subway, steamer, the aircraft etc., belong to a kind of device of testing tube joint performance.
Background technology
At present, the test that is used for the testing tube joint performance mainly is made up of withstand voltage test, explosion bulge test, pulse testing, vibration test, air-tight test and vacuum test, above-mentioned six kinds of tests are applied voltage test, and they are used to test the pipe adapter that is installed on the static equipment and have good effect really.But because the use face of pipe adapter is more and more wider, much run at high speed and pipe adapter all is installed in the pipeline on the equipment, as automobile, train, subway, steamer, more pipe adapter all is installed on the aircraft etc., if only adopt above-mentioned six kinds of test methods to test the performance that is used to be installed in the pipe adapter on the equipment of running at high speed is comprehensive inadequately, not only the working pressure of the pipe adapter inside on these equipment is bigger, and the weight of these equipment is very big usually, can there be very large inertia in these equipment in the process of running at high speed, in case the situation of brake hard appears in equipment, different parts on the equipment are because quality is inequality, their amount of force suffered under inertia effect is also inequality, thereby the situation of relative displacement occurs taking place between the different parts.If the pipe adapter on the equipment does not possess certain anti-pull-out force performance, in when, between the different parts relative displacement taking place on the equipment when, pipe adapter will be subjected to the pull-out force that produced between the different parts, thereby occur the pipe adapter phenomenon that pull-off is come out from pipeline, finally cause pipeline leakage, the equipment that makes is difficult to normal operation, the serious accident that the fatal crass also can occur.This shows, the pipe adapter that is installed on the equipment of running at high speed must possess certain anti-pull-out force performance, but also there is not a kind of device that is used for the anti-pull-out force performance of testing tube joint at present, more there is not a kind of device that is used for the anti-pull-out force performance of testing tube joint under in working order, promptly be used to test the anti-pull-out force performance when having working pressure in the pipe adapter, thereby buried huge potential safety hazard for the equipment of running at high speed, reduced the overall performance of the equipment of running at high speed.
People adopt the structure that changes pipe adapter to improve the pull-out force of pipe adapter usually now, as open day was on 03 01st, 2000, publication number is in the Chinese patent of CN2366667, a kind of pipe joint locking sleeve is disclosed, it is made up of body, in body, be provided with ring gear, its tube wall is provided with groove, though this pipe joint locking sleeve can improve the anti-pull-out force of pipe fitting joint greatly, thereby make the pipe fitting better tightness, but,, be difficult to better use such pipe joint locking sleeve owing to also be not used in the device of the anti-pull-out force performance of testing tube joint at present.Open for another example day is on 05 16th, 2007, publication number is in the Chinese patent of CN1963140, a kind of superhigh-pressure boring hose joint is disclosed, this superhigh-pressure boring hose joint comprises the linkage section that sleeve and core bar ring set join and constitute, on sleeve endoporus that constitutes linkage section and core bar outer round surface successively respectively corresponding matching be connected with anti-pulling-and-doffing section, seal section and transition section, anti-pulling-and-doffing section and seal section all are on sleeve endoporus and core bar outer round surface, be respectively equipped with a plurality of annular grooves and protruding corresponding matching or the sealing formation of joining, this superhigh-pressure boring hose joint tightens up by the locking which is provided with transition section, having prevented effectively that slipping away of sebific duct bore seal glue-line is outer moves the damage of tearing that is caused, and can effectively guarantee the anti-pulling-and-doffing performance and the sealing of rubber hose coupling.In like manner, though this superhigh-pressure boring hose joint can effectively improve the anti-pull-out force of pipe fitting joint,,, be difficult to better use such pipe joint locking sleeve owing to also be not used in the device of the anti-pull-out force performance of testing tube joint at present.
In sum, also do not have at present a kind of device that is used for the anti-pull-out force performance of testing tube joint under in working order, be difficult to realize the reasonable use of pipe adapter, limited the applicable surface of pipe adapter to a certain extent, simultaneously, also be difficult to promote the overall performance of the equipment of running at high speed.
