Abstract
The utility model relates to a tube plug for an optical hole, comprising a position locating screw with front end thereof arranged in an optical hole. A rubber ring is in the optical hole and sleeved on the screw; the end part of the optical hole is arranged with a clamping sleeve and a clamping bolt which is used for clamping the optical hole; the rear end of the position locating screw gets out from the clamping sleeve, and an impacting nut is arranged on the position locating screw. When the tube plug is used, the tube end of the optical hole is tightly clamped by the clamping bolt on the clamping sleeve, and the position locating screw is regulated by the impacting nut so that the rubber ring is compressed axially to radially swell, thus sealing the optical hole.
Description
Technical field
The utility model relates to a kind of unthreaded hole pipe plug.
Background technique
Existing GE locomotive pipe pipeline connector all is to adopt the unthreaded hole welded fitting, can not adopt common screwed pipe plug when carrying out the locomotive pipeline water-tight test.Simultaneously, because the pipe end of GE locomotive pipeline all adopts unthreaded hole, the tolerance of its internal diameter is bigger, can not play seal action with 0 RunddichtringO; And end face also cannot compress, and does not have seal action.This has brought difficulty for the locomotive pipeline water-tight test.
The model utility content
The technical problems to be solved in the utility model provides a kind of unthreaded hole pipe plug, carries out leakage test with convenient locomotive pipeline to the band unthreaded hole.
In order to solve the problems of the technologies described above, the utility model provides a kind of unthreaded hole pipe plug, comprising: front end is located at the positioning screw in the unthreaded hole, is with rubber ring in unthreaded hole and on positioning screw; The unthreaded hole end is provided with gripping sleeve, is provided with the clamping screw that is used to clamp unthreaded hole; The rear end of positioning screw passes from gripping sleeve, which is provided with gland nut.
The front end of described positioning screw is the T font, with the location rubber ring, guarantees its seal action.
The cross section of described gripping sleeve is a concave shape, so that the unthreaded hole end is stretched in the gripping sleeve, and by clamping screw that gripping sleeve and unthreaded hole is fixed to one another.
Described clamping screw has a pair of and is symmetricly set on the sidewall of gripping sleeve, thereby makes the unthreaded hole two ends stressed evenly, and is fixed to one another to guarantee gripping sleeve and unthreaded hole.
Described clamping screw has three to four and be uniformly distributed on the sidewall of gripping sleeve, thereby makes the unthreaded hole two ends stressed evenly, and is fixed to one another to guarantee gripping sleeve and unthreaded hole.
Technique scheme of the present utility model has the following advantages compared to existing technology: (1) unthreaded hole pipe plug of the present utility model, during use, clamp the pipe end of unthreaded hole by the clamping screw on the gripping sleeve, adjust positioning screw with turnbuckle, make rubber ring be subjected to axial compression, producing radially splashes rises, and plays the effect of sealing unthreaded hole.Through overtesting, under the situation of pressure 965kPa, do not leak, played seal action.This kind pipe plug is simple to operate, and is safe and reliable, satisfies technological requirement, with low cost, has better practicability.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the cross-sectional view of unthreaded hole pipe plug of the present utility model.
Embodiment
(embodiment 1)
See Fig. 1, the unthreaded hole pipe plug of present embodiment has front end and is located at positioning screw 4 in the unthreaded hole 6, is with rubber ring 5 in unthreaded hole 6 and on positioning screw 4; Unthreaded hole 6 ends are provided with gripping sleeve 1, are provided with the clamping screw 2 that is used to clamp unthreaded hole 6; The rear end of positioning screw 4 passes from gripping sleeve 1, which is provided with gland nut 3.
The front end of described positioning screw 4 is the T font.
The cross section of described gripping sleeve 1 is a concave shape.
Described clamping screw 2 has a pair of and is symmetricly set on the sidewall of gripping sleeve 1.
Described clamping screw 2 has three to four and be uniformly distributed on the sidewall of gripping sleeve 1.
During use, by the pipe end of the 2 clamping unthreaded holes 6 of the clamping screw on the gripping sleeve 1, adjust positioning screws 4 with turnbuckle 3, make rubber ring 5 be subjected to axial compression, producing radially splashes rises, and plays sealing unthreaded hole 6 and acts on.
Obviously, the foregoing description only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all mode of executions.And these belong to conspicuous variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.
