At use glue injection machine in the process of injecting glue in crack, glue flows out via the gap of valve core frame 32 under the effect of self pressure and rubber bag tank 1 applied pressure from rubber bag tank 1, and flow into hole for injecting glue 53 via the surrounding of valve core head 31, and be injected into crack from hole for injecting glue 53, along with the prolongation of injecting glue time, glue in rubber bag tank 1 is fewer and feweri, the pressure of glue self and to be subject to the increasing pressure of rubber bag tank 1 little, this just makes finally to have the insufficient pressure that small part glue is subject to and flows out from rubber bag tank 1 to make this part glue and be injected in crack.Unresolved the problems referred to above, in a preferred embodiment, are provided with inner core in rubber bag tank 1.Owing to being provided with inner core in rubber bag tank 1, inner core occupies the segment space in rubber bag tank 1, the process of glue is being injected in rubber bag tank 1, when the pressure of the glue injected is identical, the amount with the glue in the rubber bag tank 1 of inner core will be lacked, by glue injection machine in the process of injecting glue in crack, the glue in rubber bag tank 1 can be injected in crack completely, thus decreases the waste of glue.
For example, if when in rubber bag tank 1, the volume of glue is X, the pressure that glue is subject to is N, and volume can be that the glue of Y is injected in crack by this rubber bag tank 1, and Y<X, then remained the glue that volume is Y-X in rubber bag tank 1.The inner core that volume is Y-X is set in rubber bag tank 1 now, when the volume of the glue then in rubber bag tank 1 is Y, the total measurement (volume) of rubber bag tank 1 is still X, the pressure that glue is subject to is still N, the volume that this rubber bag tank 1 can be injected into the glue in crack is Y, and the volume due to the glue be equipped with in this rubber bag tank 1 is Y, therefore, the rubber bag tank 1 being inside provided with inner core can make the amount remaining glue in rubber bag tank 1 reduce, thus decreases the waste of glue.
The material of inner core is not limit, because compared with metal bar, the lighter in weight of the sticking plaster 11 of same volume, therefore inner core is preferably sticking plaster 11.
In order to avoid the through hole of spool baffle plate 4 is blocked by one end of sticking plaster 11, make glue cannot flow to the gap location of valve core frame 32 from the through hole of spool baffle plate 4, therefore, preferably, the diameter of sticking plaster 11 is less than the diameter of through hole, design like this, even if when one end of sticking plaster 11 arrives to through hole, glue still can flow out from the gap of sticking plaster 11 with through hole.But when the volume of required sticking plaster 11 is larger, diameter sticking plaster 11 can being made two end regions is less than the diameter of zone line, and the diameter of two end regions of sticking plaster 11 is less than the diameter of the through hole of spool baffle plate 4, design like this, can ensure that the volume of sticking plaster 11 meets the requirements of the through hole simultaneously avoiding sticking plaster to block certain spool baffle plate 4.
