Description
Technical field
The utility model is related to bearing device on-line pressure sealant technical field more particularly to a kind of drilling of valve stuffing box are with pressure
Seal special anti-leaking connector.
Background technology
Existing national on-line pressure sealant technical specification ---《Bearing device on-line pressure sealant technical specification》GBT 26467-
In 2011, when the on-line pressure sealant of valve stuffing box drills at stuffing-box, adopt one piece of easy baffle and protected,
Method schematic diagram is illustrated in fig. 1 shown below：
The disadvantages of this method has：
（One）Although some baffles protect, but still there is higher operating risk：
In boring procedure, since drilling rod is not sealing, drills through medium injection after stuffing-box wall and go out.Although there is baffle to prevent
Shield, but it is positive direction, local stop, and side is no any stop, is hindered so operator still has by medium
Harmful risk.Such as：Scalded by high temperature and high pressure steam, poisonous and harmful medium injury etc..Also it is exactly if that medium is inflammable easy
Quick-fried, safety in production, operating environment to whole scene are also unfavorable.
（Two）It is inconvenient to drilling operation：
Since baffle is not fixed, there are unstability, so in boring procedure, operator needs while operation is bored
Machine also needs one side regulating fender position（Or by another person's auxiliary operation）, thus it is very inconvenient to drilling operation.Particularly
The operating mode this point of inclement condition shows more very, such as：In the case that high steam leakage rate is larger, live steam fog is boundless and indistinct, depending on
Wild environment is poor and high temperature again, and bore operation inherently causes operator larger psychological pressure in such a case, adjusts
Baffle is more the increase in an operation content for operator, thus operates extremely inconvenient.
Utility model content
The utility model provides a kind of valve stuffing box drilling special anti-leaking connector of on-line pressure sealant, makes entirely to drill
Journey operates under whole sealing status, and medium does not leak, to ensure bore operation essential safety；It is simple in structure, installation operation is convenient,
It is versatile.
In order to solve the above technical problems, the embodiment of the present application provides, a kind of valve stuffing box drilling on-line pressure sealant is special to be prevented
Leaky junction, including the hollow adapter body that can pass through drilling rod, one end of adapter body is in outer to borehole sealing
The thin tube-like of screw thread, the other end of adapter body, which is equipped with, compresses plug, and bullet is equipped between the compression plug and adapter body
Property filler is additionally provided with rotary switch in the adapter body on the inside of the elastic filler.
As a preferred technical solution of utility model, one end that adapter body installation compresses plug is equipped with
Internal thread chamber, the elastic filler are filled in internal thread intracavitary, and the compression plug is in that can make the hollow form that drilling rod passes through,
Its outer surface is equipped with and the matched external screw thread of internal thread chamber.
The one or more technical solutions provided in the embodiment of the present application, have at least the following technical effects or advantages：
Entire boring procedure is made to be operated under whole sealing status, medium does not leak, to ensure bore operation essential safety；Knot
Structure is simple, installation operation is convenient, versatile.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in not making the creative labor property
Under the premise of, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the structure diagram of the prior art；
Fig. 2 is the overall structure figure of the utility model；
Fig. 3 is the utility model schematic diagram in use.
In figure：1st, adapter body, 2, compress plug, 3, elastic filler, 4, rotary switch, 5, drilling rod, 6, internal thread chamber.
Specific embodiment
In order to better understand the above technical scheme, in conjunction with appended figures and specific embodiments to upper
Technical solution is stated to be described in detail.
As shown in Fig. 2-Fig. 3, a kind of valve stuffing box drilling special anti-leaking connector of on-line pressure sealant described in the present embodiment,
Including the hollow adapter body 1 that can pass through drilling rod 5, one end of adapter body 1 is in externally threaded to borehole sealing
Thin tube-like, the other end of adapter body 1, which is equipped with, compresses plug 2, and elasticity is equipped between the compression plug 2 and adapter body 1
Filler 3 is additionally provided with rotary switch 4 in the adapter body 1 of 3 inside of the elastic filler.
Wherein, in the present embodiment, the adapter body 1 installation compresses one end of plug 2 equipped with internal thread chamber 6, institute
The elastic filler 3 stated is filled in internal thread chamber 6, and the compression plug 2 is in that can make the hollow form that drilling rod 5 passes through, appearance
Face is equipped with and 6 matched external screw thread of internal thread chamber.
The function of all parts is as follows：
The realization of adapter body 1 couples with stuffing-box bore position, the supporting body of the other component functions of anti-leaking connector；
Elastic filler 3：Critical seal element by being compressed to it, realizes drilling rod sealing；
Compress plug 2：Elastic filler is compressed；
Cock switch 4：Drilling is completed, and after exiting drilling rod, rotary closing realizes the cut-out of anti-leaking connector glue injection channel,
Prevent medium from releasing.
Its sealing mechanism is：
It completes drilling blind hole on stuffing-box wall, after tapping female bore, this anti-leaking connector is coupled with threaded hole installation.Installation
