Embodiment
Below in conjunction with the drawings and specific embodiments the present invention done and specifically describe in detail further
.
As shown in the figure, the micro-channel parallel flow aluminum pipe water injection end packoff of hydraulic bursting test machine, the upper holder block 4 comprising lower lock block 6 and match with lower lock block 6, described lower lock block 6 has a columniform upper end, the lower seal pickup groove 5 of the annular that a center line and upper end center line coincide is provided with at the end face of described upper end, on entity within described lower seal pickup groove 5 inner peripheral surface, plane I 14 is lower than Planar Mechanism 15 on the entity beyond lower seal pickup groove 5 outer circumference surface, O RunddichtringO 11 is provided with in lower seal pickup groove 5, described O RunddichtringO 11 excircle be provided with one section of groove be directed radially through for test specimen 12, the size of groove is arranged according to the width of the sample that will test, the breach 13 that an availability test sample 12 is directed radially through is provided with in the side of described lower seal pickup groove 5, the size of described breach 13 is arranged according to the width of the sample that will test.
The lower surface of described upper holder block 4 is provided with the upper O-ring seal pickup groove 3 matched with described O RunddichtringO 11, in order to slippage go out from the groove of O RunddichtringO 11 at warranty test sample 12 in water filling pressurization in test specimen 12, the lower surface of described upper holder block 4, is also provided with the anti-slop serrations 2 for stinging tight test specimen 12 within the inner periphery of upper O-ring seal pickup groove 3.
The annular protrusion that centered by described anti-slop serrations 2, line and upper holder block 4 center line coincide.
Described annular protrusion can be one, and also can be a plurality of, a plurality of annular protrusion can be called as waveform anti-slop serrations.The lower edge of described annular protrusion can be plane, also can be arcwall face, so that test specimen 12 can be compressed and don't puncture test specimen 12 for suitable, and the lower edge of described annular protrusion is lower than the outer circumferential end face of upper O-ring seal pickup groove 3, after can ensureing that O-ring seal pickup groove 3 coordinates with lower seal pickup groove 5 like this, anti-slop serrations 2 can compress the part extend within O RunddichtringO 11 inner periphery, and will ensure test specimen 12 thoroughly not to be flattened the microchannel 19 blocking the inside.
One is axially arranged with for be connected with the water inlet pipe 8 of water filling pressue device and to the waterflood path 7 of test specimen 12 water filling at lower lock block 6.
One end that described waterflood path 7 is connected with water inlet pipe 8 be provided with install O-ring seal heavy stand 16.
The middle part of described lower lock block 6 be provided with one for installing on testing table 1 lower lock block 6 time location the pilot hole 10 of axis, in order to the air avoiding blind hole to bring when location hinders, thus make lower lock block 6 more accurate in the location of testing table 1, thus ensureing that the work of whole water injection end packoff is more reliable, described pilot hole 10 is preferably through hole.
Like this, when test needs to carry out, after test specimen 12 i.e. micro-channel parallel flow aluminum pipe one end is penetrated from the upper groove of O RunddichtringO 11, O RunddichtringO 11 is placed in lower seal pickup groove 5, micro-channel parallel flow aluminum pipe passes through from described breach 13, because plane I 14 is lower than Planar Mechanism 15 on the entity beyond lower seal pickup groove 5 outer circumference surface on the entity within described lower seal pickup groove 5 inner peripheral surface, so when upper holder block 4 is under the driving of dynamical element, downwards and lower lock block 6 seals time, the part that described test specimen 12 is able within O RunddichtringO 11 inner periphery can not upper holder block 4 jack-up, thus ensure the effect of sealing.Anti-slop serrations 2 be also just in time pressed in test specimen 12 extend into O RunddichtringO 11 inner periphery within part, fix further test specimen 12, it is suitable that described test specimen 12 pierces into length within O RunddichtringO 11 inner periphery with the outlet sealing pilot hole 10 and expose waterflood path 7.
