Embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are described in detail.
With reference to shown in Fig. 1 ~ Fig. 2, the suction tube device of anti-backflow described in the utility model, comprise top suction pipe 1, annulus 2 and bottom suction pipe 8, one end of top suction pipe 1 is welded with Draw bar lock 4, annulus 2 is set in top suction pipe 1 and and is positioned at (annulus 2 makes according to the diameter of top suction pipe 1) inside Draw bar lock 4 outward, being symmetrically welded two pull bars 3 parallel with top suction pipe 1 on annulus 2, the position that Draw bar lock 4 connects with annulus 2 is provided with pull bar handle (for pushing drawing rod 3 activity, realizing the operation to pull bar 3);
The upper end of bottom suction pipe 8 processes a card groove 5, the other end of top suction pipe 1 arranges groove, the caliber size of groove meets card groove 5 tight butt of itself and bottom suction pipe, and a vacuum breaker 6 is installed at the middle part of bottom suction pipe 8, arranges many tubules 7 in the bottom suction pipe 8 of vacuum breaker 6 bottom; Pull bar 3 is connected with bottom suction pipe 8 near one end of groove (top suction pipe 1 passes through pull bar 3 and is flexibly connected formation entirety with bottom suction pipe 8), and Draw bar lock 4 and pull bar handle coordinate the stroke of control pull bar 3, and drive top suction pipe 1 is separated and combination with bottom suction pipe 8.
The making method of the suction tube device of the anti-backflow of the utility model, comprises the steps:
1) choose a suction pipe, the length of suction pipe according to treating the height of liquids apparatus for placing determine;
2) suction pipe bottom is cut a segment (about 200mm), for making the bottom suction pipe 8 of suction tube device;
3) making method of top suction pipe 1: first using the suction pipe that cuts as top suction pipe 1, process a groove with lathe in one end of top suction pipe 1, so that carrying out and the connection of bottom suction pipe 8;Then diameter according to suction pipe makes an annulus 2, two pull bars 3 are welded in the both sides of annulus 2, and pull bar 3 is parallel with top suction pipe 1, weld a Draw bar lock 4 in one end of the undressed groove of top suction pipe 1, being enclosed within by annulus 2 inside Draw bar lock 4, the stroke of Draw bar lock 4 is set to 100mm;
4) making method of bottom suction pipe 8: using the segment suction pipe that cuts as bottom suction pipe 8, utilize lathe to process a card groove 5 in one end of bottom suction pipe 8, and sealing-ring is set at the position of card groove 5 with groove fit. then one end by band card groove 5 cuts a segment again, then by remaining part two steel plate shutoff, and then evenly open many apertures, thinner pipe is selected all to be linked by multiple aperture, then it is firm to be welded with hole periphery by pipe, finally all unnecessary tube heads are excised, polishing flat completes one the sleeve pipe of many tubules 7, then a vacuum breaker 6(is selected or voluntarily with spring, steel plate makes) it is welded on one end of bottom suction pipe 8, and then the one section of suction pipe scaling off the inner card groove 5 of band is welded on vacuum breaker 6, vacuum breaker 6 is made to be in centre,
5) after top suction pipe 1 and bottom suction pipe 8 all complete, top suction pipe 1 and bottom suction pipe 8 are carried out tight butt (the card groove of the groove tight butt bottom suction pipe 8 of top suction pipe 1), then pull bar 3 is moved to the upper limit of railing lock 4, again the bottom of pull bar 3 is welded with bottom suction pipe 8, it is after an entirety that top suction pipe 1 and bottom suction pipe 8 connect, carry out grinding process, complete.
When using this suction tube device to draw liquid, hose connection by top suction pipe 1 and liquids pump, then by pull bar 3(pull bar handle) shift lower limit onto, make the space leaving about 100mm between top suction pipe 1 and bottom suction pipe 8, then bottom suction pipe 8 is inserted in liquid to be inhaled and go, open liquids pump to carry out drawing liquid, when becoming few to liquid, move pull bar 3 to upper limit, and lock with Draw bar lock 4, then carry out drawing liquid, liquid will be drawn as much as possible clean, pull bar 3 controls top suction pipe 1 and is separated with bottom suction pipe 8 and is the speed drawing liquid to ensure not affect when liquid level is high with combining and can guarantee that when liquid level is low liquid can all blot only.
Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to enforcement mode of the present utility model. For those of ordinary skill in the field, apparent change or the variation extended out according to spirit of the present utility model are still among protection domain of the present utility model.
