The purpose of this invention is to provide a kind of applied widely, particularly be applicable to that the locus is little, require the air cannon block-removing device of multiple spot block clearing.
The present invention forms by the air bubble body with through the air bubble head that flange is mounted on air bubble body two ends, the air bubble head by flanged (FLGD) three-way pipe, be installed in inner nozzle in the three-way pipe, end cap, in end cap is installed in three-way pipe cylinder body be installed in cylinder body in and can form relative to the plunger that cylinder body moves, have the admission port that connects external admission line on the end cap, have check valve at the center of plunger.
Because the present invention has two air bubble heads that are mounted on air bubble body two ends through flange, not only make the air cannon block-removing utensil that two spray seam brokens are arranged, and nationality helps flange bonded assembly relative position to change to determine two relative positions between the spray seam broken as required, adapting to the occasion of different block clearings, thereby reach purpose of the present invention.
Below in conjunction with accompanying drawing the present invention is further elaborated.
The present invention is by an air bubble body 1 and a left side, right air bubble head 2,3 form, air bubble body 1 is the pressure air container of hollow, its two ends have fixed flange 4,5, a left side, right air bubble head 2,3 by band fixed flange 6, a left side of 7, right three-way pipe 8,9, a left side, right inner nozzle 10,11, a left side, right end cap 12,13, a left side, right cylinder body 14,15 and left, right plunger 16,17 form, a left side, right air bubble head 2,3 through flange 6,7,4,5 are installed on the air bubble body 1, a left side, right inner nozzle 10,11 through being stuck in fixed flange 4,5 and 6, flange 18 between 7,19 are installed in a left side, right three-way pipe 8, in 9 the levelling pipe, a left side is housed, right cylinder stops 14, a left side of 15, right end cap 12,13 are installed in a left side respectively, right three-way pipe 8, the end of 9 levelling pipe, a left side, right plunger 16,17 1 ends are installed in a left side, right cylinder body 14, also can be left relatively in 15, right cylinder body 14,15 move axially, its other end has and is stretching out a left side, right cylinder body 14,15 o'clock with left, right inner nozzle 10,11 end anastomosis and leak free flange 20,21, on a left side, right plunger 16,17 center has check valve 22,23, on a left side, right end cap 12, has admission port 24 on 13,25, a left side, right three-way pipe 8,9 vertical tube is spray seam broken 26,27.
To spray at first before the operation that seam broken 26,27 inserts must the block clearing places, then check valve 22,23, left and right inner nozzle 10,11 on the admission port 24,25 of pressurized air on left and right end cap 12,13, left and right cylinder body 14,15, the left and right plunger 16,17 are entered in the chamber of air bubble body 1.When carrying out the block clearing operation, handle the electromagnetic valve on the external pipeline, make admission port 24,25 be exhaust condition, move towards the direction of leaving left and right inner nozzle 10,11 rapidly under the pressure air effect of left and right sides plunger 16,17 in air bubble body 1, thereby pressure air is entered in the left and right three-way pipe 8,9 rapidly from the gap of left and right plunger 16,17 and 10,11 formation of left and right inner nozzle, and rapidly from spray seam broken 26,27 ejections, form strong air-flow, directly pour bottleneck area with ultrasonic speed, finish the block clearing operation.
