For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of rubber cup device that is applicable to detection in pipe leakage, rubber cup can automatically be got rid of resistance and drive detector to continue operation when change through joint, pipeline wall thickness and valve etc. located, and avoids pipeline shutdown or booster occurs.
The technical solution of the utility model is achieved in that a kind of rubber cup device that is applicable to detection in pipe leakage, comprise at the bottom of having bowl, the rubber cup on bowl wall and bowl edge, on the described bowl of wall inner side surface that closes on described bowl edge, be provided with one-level exclusion groove, described one-level exclusion groove is along the circumferencial direction setting on described bowl edge on described bowl wall inner side surface, and the groove depth of described one-level exclusion groove is 1/2nd to 2/3rds of described bowl wall thickness.
The above-mentioned rubber cup device that is applicable to detection in pipe leakage, on the described bowl wall inner side surface of the described bowl end and described bowl wall adjoiner, be provided with secondary exclusion groove, described secondary exclusion groove is along the circumferencial direction setting at the end of described bowl on described bowl wall inner side surface, and the groove depth of described secondary exclusion groove is 1/3rd to 1/2nd of described bowl wall thickness.
The above-mentioned rubber cup device that is applicable to detection in pipe leakage, rubber cup device also comprises exclusion frame, annular exclusion dish and exclusion Compress Spring, on the circumferential surface of described exclusion frame and along the circumferencial direction of described exclusion frame, be provided with three grades of exclusion grooves, the interior annular edge of described annular exclusion dish is positioned at described three grades of exclusion grooves, and be Spielpassung between the interior annular edge of described annular exclusion dish and described three grades of exclusion groove inwalls, one end of described exclusion Compress Spring is connected with the interior annular edge of described annular exclusion dish, the other end of described exclusion Compress Spring is fixedly mounted on the bottom land of described three grades of exclusion grooves, the outer side of described annular exclusion dish is along being fixedly installed togather with the described bowl end.
The beneficial effects of the utility model are: the rubber cup of the utility model rubber cup device can automatically be got rid of resistance and drive detector to continue operation when change through joint, pipeline wall thickness and valve etc. located, and avoids pipeline shutdown or booster occurs.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is applicable to the rubber cup of the rubber cup device of detection in pipe leakage;
Fig. 2 is the structural representation that the utility model is applicable to the rubber cup device of detection in pipe leakage.
In figure: 2-1-rubber cup, at the bottom of 2-2-bowl, 2-3-bowl wall, 2-4-bowl edge, 2-5-one-level exclusion groove, 2-6-secondary exclusion groove, 2-7-exclusion frame, 2-8-annular exclusion dish, 2-9-exclusion Compress Spring, tri-grades of exclusion grooves of 2-10-.
Embodiment
As depicted in figs. 1 and 2, the rubber cup device that is applicable to detect in pipe leakage comprise have bowl at the bottom of 2-2, bowl wall 2-3 and bowl along the rubber cup 2-1 of 2-4, closing on described bowl along being provided with one-level exclusion groove 2-5 on the described bowl wall 2-3 inner side surface of 2-4, described one-level exclusion groove 2-5 is the circumferencial direction setting along described bowl along 2-4 on described bowl wall 2-3 inner side surface, and the groove depth of described one-level exclusion groove 2-5 is 1/2nd to 2/3rds of described bowl wall 2-3 thickness.Make so described bowl can make described bowl curve inwardly along 2-4 when 2-4 runs on inner-walls of duct less obstruction, thereby detector is broken the barriers smoothly.
On the described bowl wall 2-3 inner side surface of described bowl end 2-2 and described bowl wall 2-3 adjoiner, be provided with secondary exclusion groove 2-6, described secondary exclusion groove 2-6 is along the circumferencial direction setting of described bowl end 2-2 on described bowl wall 2-3 inner side surface, and the groove depth of described secondary exclusion groove 2-6 is 1/3rd to 1/2nd of described bowl wall 2-3 thickness.At described bowl, along 2-4, run on inner-walls of duct in larger obstacle, when described bowl relies on the space of described one-level exclusion groove 2-5 to curve inwardly to be not enough to make detector to break the barriers smoothly along 2-4, described bowl wall 2-3 can whole curve inwardly, thereby make described bowl larger along the aduncate angle of 2-4, be convenient to detector smoothly by larger obstacle.
Rubber cup device also comprises exclusion frame 2-7, annular exclusion dish 2-8 and exclusion Compress Spring 2-9, on the circumferential surface of described exclusion frame 2-7 and along the circumferencial direction of described exclusion frame 2-7, be provided with three grades of exclusion groove 2-10, the interior annular edge of described annular exclusion dish 2-8 is positioned at described three grades of exclusion groove 2-10, and be Spielpassung between the interior annular edge of described annular exclusion dish 2-8 and described three grades of exclusion groove 2-10 inwalls, one end of described exclusion Compress Spring 2-9 is connected with the interior annular edge of described annular exclusion dish 2-8, the other end of described exclusion Compress Spring 2-9 is fixedly mounted on the bottom land of described three grades of exclusion groove 2-10, the outer side of described annular exclusion dish 2-8 is along being fixedly installed togather with described bowl end 2-2.When detector process joint or valve, even whole the curving inwardly of described bowl wall 2-3, can not make detector pass through smoothly, at this moment the active force that inner-walls of duct applies described rubber cup 2-1 makes described annular exclusion dish 2-8 to the bottom motion of described three grades of exclusion groove 2-10, described in when running into like this on tube wall larger obstacle, rubber cup 2-1 can move downward, and guarantees that detector passes through smoothly.After detector passes through, the elastic force of described exclusion Compress Spring 2-9 makes described annular exclusion dish 2-8 towards the direction motion away from described three grades of exclusion groove 2-10 bottom, make described rubber cup 2-1 still with inner-walls of duct close contact, guarantee that detector has enough onward impulses.
Above-described embodiment is only for the invention example is clearly described, and the not restriction to the invention embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all mode of executions.And the apparent variation of being amplified out thus or change are still among the protection domain in the invention claim.
