Abstract
The utility model relates to a seal pipe plug for plain hole joints, which resolves the technical problems for sealing plain hole joint in high pressure pipelines. The seal pipe plug comprises a seal ring, a top plate, a bottom plate and at least one fastening screw rod couple for connecting the top plate and the bottom plate, wherein the top plate is arranged at the open end of a plain hole joint for connecting a locomotive pipeline, the bottom plate is fixed at the another end of the plain hole joint, the seal ring is arranged between the top plate and the open end of the plain hole joint. After filling high pressure gas, the force of the high pressure gas on the top plate is transferred to the bottom plate via the fastening screw rods to keep the force balance of the top plate and confirm seal effect.
Description
Technical field
The utility model relates to the unthreaded hole joint sealing plug for pipe that is applied in the pressure duct.
Background technique
In the prior art, need test to the sealing of as shown in Figure 1 locomotive pipeline.Method commonly used is to detect its sealing by the inflation manometric test.Adopt threaded pipe joint the joint of original locomotive pipeline (as tee union, elbow and straight coupling etc.), adopt threaded pipe plug to seal.
And the pipe joint of existing GE locomotive all is to adopt the unthreaded hole joint, and above-mentioned existing threaded pipe plug can not use.Because this pipeline need bear 10Kg/cm when normal the use
2Air pressure, so overslaugh the inflation manometric test enforcement, so can't test to the sealing of existing GE locomotive pipeline.
The model utility content
Technical problem to be solved in the utility model provides the unthreaded hole joint sealing plug for pipe of salable unthreaded hole joint in pressure duct.
For solving the problems of the technologies described above, the utility model provides a kind of unthreaded hole joint sealing plug for pipe, comprising: seal ring, top board, base plate and being used to connect top board and base plate at least one pair of tighten up screw rod; Top board is arranged on the opening end that is used for the unthreaded hole joint that is connected with the locomotive pipeline, and base plate is fixed at the other end of unthreaded hole joint; Seal ring is located between the opening end of top board and unthreaded hole joint.
Described unthreaded hole joint is straight coupling, tee union or elbow.
Described top board is provided with the locating bump that matches with the opening end of described unthreaded hole joint.
The utlity model has positive effect: (1) unthreaded hole joint of the present utility model is with in the sealing plug for pipe, and top board is by tightening up screw rod and base plate is fixed, and seal ring is used to seal the opening end of unthreaded hole joint; After charging into pressurized gas, the power that pressurized gas act on the top board is transmitted on the base plate by tightening up screw rod, thereby keeps the stress balance of top board, is applicable to sealing unthreaded hole joint in pressure duct.

Embodiment
(embodiment 1)
See Fig. 2-5, the unthreaded hole joint of present embodiment comprises with sealing plug for pipe 5: seal ring 5-4, top board 5-2, base plate 5-1 and being used to connect top board 5-2 and base plate 5-1 at least one pair of tighten up screw rod 5-3; Top board 5-2 is arranged on the opening end of the unthreaded hole joint that is connected with locomotive pipeline 1, and base plate 5-1 is fixed at the other end of unthreaded hole joint; Seal ring 5-4 is located between the opening end of top board 5-2 and unthreaded hole joint.
Top board 5-2 is by tightening up screw rod 5-3 and base plate 5-1 fixes, and seal ring 5-4 is used to seal the opening end of unthreaded hole joint; After charging into pressurized gas, the power that pressurized gas act on the top board 5-2 is transmitted on the base plate 5-1 by tightening up screw rod 5-3, thereby keeps the stress balance of top board 5-2, has guaranteed sealing effect.
See Fig. 1, when detecting the sealing of locomotive pipeline 1 by the inflation manometric test, the pipe plug that present embodiment is set 5 on all unthreaded hole joints on the locomotive pipeline 1 (comprising: straight coupling 2, tee union 3 and elbow 4).Locomotive pipeline 1 also is provided with barometer 6 by linking to each other with compressed gas source 8 on the locomotive pipeline 1.
When beginning to detect, mainly open air valve 7, it is 10Kg/cm that compressed gas source 8 just fills pressurized gas to air pressure to this locomotive pipeline 1
2, close gas check valve 7 then, can judge the sealing of locomotive pipeline 1 by the situation of change of observing barometer 6.
See Fig. 3-5, described top board 5-2 is provided with the locating bump 5-2-1 that matches with the opening end of described unthreaded hole joint, so that location and installation.
Obviously, the foregoing description of the present utility model 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.
