Abstract

The utility model discloses a hole sealing device, which comprises a threaded rod, wherein a rubber sleeve is sleeved at the end, close to the head, of the threaded rod, and a taper sleeve is sleeved at the end, close to the tail, of the threaded rod; a nut is arranged at the tail of the threaded rod, and is arranged above the taper sleeve; the head of the threaded rod is designed into a taper A; a lower inner taper and an upper inner taper are arranged at the two ends of the rubber sleeve respectively; the head of the taper sleeve is designed into a taper B; the taper A is matched with the lower inner taper body of the rubber sleeve; the taper B is matched with the upper inner taper of the rubber sleeve. According to the hole sealing device, the rubber sleeve and the taper sleeve are arranged on the threaded rod, the nut is arranged at the tail of the threaded rod, and the taper sleeve is tightly attached to the inner wall of a sealed part after being deformed by squeezing the rubber sleeve to fill a gap between the threaded rod and the sealed part, thereby fulfilling the aim of sealing; the hole sealing device is simple in structure, easy to manufacture, wide in application range and low in manufacturing cost, and can be widely applied to sealing tests in pipes, shells or solids.

Description

A kind of hole seal arrangement
Technical field
The utility model belongs to the experimental technique field of detecting, and relates to a kind of seal arrangement, specifically relates to a kind of hole seal arrangement of using while doing leakage test on tubing, Shell-Class or entity.
Background technique
Existing tubing, Shell-Class or entity are when doing leakage test, endoporus is generally and in endoporus, packs seal ring into and carry out radial seal with encapsulating method, or at hole end surface, with gland, add seal ring and carry out axial end sealing, technology maturation own, can meet the seal request of most positions endoporus.But because part endoporus aperture is special, without the seal ring of planning standard, process separately special non-standard seal ring high cost, not feasible; Axial end sealing is owing to being limited by design of part, sometimes can not adopt or inconvenience adopts, though adopting of having, because axial end sealing configuration is more complicated, it is inconvenient to operate, manufacture cost is high.
Model utility content
In order to solve when doing leakage test, in numerous parts endoporus can not or the problem of inconvenience sealing, the utility model provides a kind of with low cost, simple to operate, hole seal arrangement that using scope is wide.
The utility model is achieved by following technical solution.
A hole seal arrangement, comprises screw rod, and described screw rod is set with gum sleeve near head one end, near afterbody one end, is set with tapered sleeve, at screw rod tail, nut is installed, and nut is placed in tapered sleeve top.
The head design of described screw rod becomes cone A, and gum sleeve two ends are respectively arranged with lower internal cones and upper internal cones, and the head design of tapered sleeve becomes cone B, and wherein cone A and lower internal cones match, and cone B and upper internal cones match.
The afterbody of described screw rod is designed to flat.
The beneficial effects of the utility model are:
Compared with prior art, the utility model by arranging gum sleeve and tapered sleeve on screw rod, and at screw rod tail, nut is housed, under the effect of nut screwing clamping power, after making tapered sleeve extruding gum sleeve produce distortion, be close to sealed part inwall, fill the gap between screw rod and sealed part, thereby reach the object of sealing.Owing to being provided with cone at screw rod and tapered sleeve head, and be designed to internal cones structure at gum sleeve two ends, make to be squeezed in process at gum sleeve, the cone of screw rod and tapered sleeve head can form and closely cooperate with the internal cones at gum sleeve two ends, thereby reaches good sealing effect.The utility model is simple in structure, be easy to manufacture, and easy to use, using scope is wide, and low cost of manufacture can be widely used in doing leakage test on tubing, Shell-Class or entity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of gum sleeve in the utility model;
Fig. 3 is the structural representation of tapered sleeve in the utility model;
Fig. 4 is the utility model embodiment schematic diagram.
In figure: 1-screw rod, 2-gum sleeve, 3-tapered sleeve, 4-nut, 5-product, 101-flat, 102-cone A, the upper internal cones of 201-, internal cones under 202-, 301-cone B, 501-endoporus.
Embodiment
Below in conjunction with accompanying drawing, further describe the technical solution of the utility model, but described in claimed scope is not limited to.
As shown in Figure 1 to Figure 3, a kind of hole described in the utility model seal arrangement, a kind of hole seal arrangement, comprise screw rod 1, described screw rod 1 is set with gum sleeve 2 near head one end, near afterbody one end, be set with tapered sleeve 3, at screw rod 1 afterbody, nut 4 is installed, and nut 4 be placed in tapered sleeve 3 tops.Adopt the technical program, make gum sleeve 2 in use, under the effect of nut screwing clamping power, make to be close to sealed part inwall after tapered sleeve 3 extruding gum sleeves 2 generation distortion, fill the gap between screw rod and sealed part, thereby reach the object that product endoporus is sealed.
The head design of described screw rod 1 becomes cone A102, gum sleeve 2 two ends are respectively arranged with lower internal cones 202 and upper internal cones 201, the head design of tapered sleeve 3 becomes cone B301, and wherein cone A102 and lower internal cones 202 match, and cone B301 and upper internal cones 201 match.Adopt the technical program, make gum sleeve 2 form and to closely cooperate with the cone B301 that is arranged at tapered sleeve 3 heads with the cone A102 that is arranged at screw rod 1 head, in the process of gum sleeve 2 extrusions, there is good sealing, further play better sealing effect.
The afterbody of described screw rod 1 is designed to flat 101.The afterbody of screw rod 1 also can be designed to the structure that other can anti-rotation in actual applications.
As shown in Figure 4, the utility model in use, first gum sleeve 2 and tapered sleeve 3 are sleeved on screw rod 1 successively, and make the lower internal cones 202 of gum sleeve 2 and upper internal cones 201 respectively with cone A102 and cone B301 no-float, then the afterbody at screw rod 1 packs nut 4 into; At the trial, the seal arrangement having assembled is directly packed in the endoporus 501 of product 5 of needs tests, then fastening nut 4, gum sleeve 2 is at the cone B(301 of screw rod 1 forecone A102 and tapered sleeve 3) axial compression produce downwards axially and radial deformation, the lower internal cones 202 of gum sleeve 2 and upper internal cones 201 are close on the inner hole wall of product 5 after the cone B301 of the cone A102 of screw rod 1 and tapered sleeve 3 extruding respectively, thereby realize the sealing to its endoporus 501.
