In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, with Lower 1 to 4 pair of the embodiment combination accompanying drawing plugging device provided by the utility model applied to the maintenance of pipeline on-line production is made specifically to explain State.
Embodiment one,
Refering to Fig. 1, for the structural representation for the plugging device embodiment one repaired applied to pipeline on-line production;With reference to Fig. 2, For the concrete application structural representation for the plugging device embodiment one repaired applied to pipeline on-line production.Such as institute in Fig. 1 and Fig. 2 Show, plugging device provided by the utility model is applied to blocking pipe 6 during pipeline maintenance, including a push rod 1 and at least one The one end of push rod 1 and the plug 2 to match with the inner diameter shape of pipeline 6 are installed on, the outside dimension of plug 2 is not less than the internal diameter of pipeline 6 Size, the method that plugging device is applied to blocking pipe include step:Step a, lubricant is applied to the periphery of plug 2, and will Plug 2 is filled in pipeline 6;Step b, maintenance operation is carried out to pipeline 6.
In the above-mentioned technical solutions, plug 2 is made up of elastomeric material, and push rod 1 is made up of metal material, can be specifically Iron or copper or other materials or wooden material, and push rod 1 can be the knot of solid rod or hollow pipe Structure.The operation of pipeline maintenance generally refers to the operation of welding but it is also possible to be operations such as appearance derusting in the present embodiment.And energy It is enough that preferable sealing effectiveness is played after pipeline 6 is filled in, avoid blocking oil, gas or water in pipeline 6 when on-line production welds Spill, the position of welding can be such as the location A marked in Fig. 2.
So as to conveniently complete the operation of pipeline on-line production maintenance, without carrying out stopping transportation before pipe-line maintenance Operation, without the large-scale plugging device of use so that the maintenance process of pipeline 6 succinctly facilitates, and greatlys save cost, avoids Unnecessary trouble, and overall structure is simple and reliable, it is easily fabricated.Specifically, the external diameter of plug 2 be more than the internal diameter 1mm of pipeline 6~ 1.5mm。
In a preferred embodiment, the one end of push rod 1 is connected with first screw rod 31, and plug 2 is set in Outside one screw rod 31, the front/rear end of plug 2 is fixed on by first nut 41 being rotatably connected on the first screw rod 31 respectively On one screw rod 31, so as to which fixed effect is preferable and is conveniently adjusted position.In addition, as can be known from Fig. 1, it is in half-conical that plug 2 is overall Type or cylindrical-shaped structure, and this is not limited to, the first screw rod 31 is formed directly to open up external screw thread in the one end of push rod 1, but also may be used The one end of push rod 1 is welded on the first screw rod 31, and the axis direction of the axial direction of the first screw rod 31 and push rod 1 is positioned at same On straight line.It is worthy of note that the shape of push rod 1 is not limited to the structure of cylinder or other are various square or special-shaped Structure, it is existing common mode, therefore is repeated no more.Further, the quantity of plug 2 is one but it is also possible to be multiple What plug 2 was arranged side by side is set in the structure outside the first screw rod 31, changes with specific reference to the demand of closure pressure.
Embodiment two,
Refering to Fig. 3, for the structural representation for the plugging device embodiment two repaired applied to the on-line production of pipeline 6;With reference to figure 4, for the concrete application structural representation for the plugging device embodiment two repaired applied to the on-line production of pipeline 6.In Fig. 1 and Fig. 2 Shown, the plugging device and above-described embodiment one that the present embodiment provides are essentially identical, and it the difference is that only, in the He of push rod 1 A flexible flexible axle 5 is provided between plug 2, and the both ends of flexible axle 5 connect push rod 1 and plug 2 respectively.Further, it is soft The one end of axle 5 away from push rod 1 is connected with second screw rod 32, and plug 2 is set in outside the second screw rod 32, before plug 2 Rear end face is fixed on the second screw rod 32 by second nut 42 being rotatably connected on the second screw rod 32 respectively, so as to fixed effect Preferably and it is conveniently adjusted position.Further, the both ends of flexible axle 5 connect the screw rod 32 of push rod 1 and second by way of welding respectively, And push rod 1, flexible axle 5, the axis direction of the second screw rod 32 are located along the same line.Specifically, as shown in Figure 4, pipeline 6 is carried out The position of maintenance is and corresponding in shown B location, and the present embodiment is primarily adapted for use in be repaired to the pipeline 6 of bent tube type Operation, by 5 flexible characteristic of flexible axle, plug 2 stretches into the intersegmental part of pipeline 6 of bending, and flexible axle 5 is commonly uses in industry Structure, can be made of the structure of bellows or the structure of hollow hoses or the softer material of quality Club or tube.
In a preferred embodiment, relative to embodiment one, in the present embodiment, above-mentioned step a also includes Step a1:Foaming agent is injected into pipeline 6 to detect the sealing of the blocking pipe 6 of plug 2.And the step in above-mentioned step Plug 2 is filled in after pipeline 6 in a.In addition, above-mentioned lubricant is butter fat, foaming agent is suds, and equal cost is relatively low but energy Access preferable effect.
In addition, being directed to the above embodiments one and embodiment two, plug 2 is overall to be made up but it is also possible to be each of rubber Kind mixing material is made.Preferably, in the inside of plug 2 embedded with ceramic block and/or iron block or other block or powders Material with strengthen closure pressure.Further, the periphery ring-type of plug 2 offers one of annular groove (not shown), And sealing ring is embedded with annular groove, to strengthen sealing effectiveness, and this plugging device cost is cheap, easy to use.It is worth pointing out , the closure requirement of pipeline 6 of oil is led to common water-through and ventilating typically in 2kg/cm2Within, closure of the present utility model Device can effectively improve the energy of plug 2 by changing the mode such as size of structure, flexible axle 5 and push rod 1 inside or outside plug 2 The closure pressure enough born, so as to be adaptable in the maintenance of the pipeline 6 of various pressure demands.Obviously, shown in Fig. 1 and Fig. 3, Screw rod penetrates the center of plug 2, and the axis direction of screw rod is mutually perpendicular to the plane where the front/rear end of plug 2.Its For normal method, therefore omit and repeat.
The utility model in a particular application, is broadly divided into two kinds of scenes:
1) it is directed to the pipeline 6 of straight pipe type, it is only necessary to the structure that plug 2 and push rod 1 connect, plug 2 is stretched into pipeline 6, The effect of plug can be achieved, and including the sealing to various media such as combustion gas and water, oil, with the operation welded.
2) pipeline 6 for bent tube type is, it is necessary to which the structure that plug 2, flexible axle 5, push rod 1 are connected with each other, utilizes the bendable of flexible axle 5 Bent characteristic, plug 2 is stretched into inside pipeline 6, then is welded, and is easy to pipeline 6 to repair.
In addition, when specifically used, the above-mentioned length for being directed to the plug used during straight pipe type pipeline should be shorter than for bend pipe The length of the plug used during type pipeline, specifically, the former length is 3/4ths of the latter's length.In addition, the end edge of plug two Edge offers rounded corner so that the both ends of plug are not limited to this in cone.
Preferred embodiment of the present utility model is the foregoing is only, is merely illustrative for the utility model, and It is nonrestrictive.Those skilled in the art understanding, can be to it in the spirit and scope that the utility model claims are limited Many changes are carried out, are changed, in addition it is equivalent, but fall within the scope of protection of the utility model.
