Abstract
The utility model provides a two components of a whole that can function independently subassemblies of first nipple joint and second nipple joint are constituteed that glass steel oil pipe connector, by steel metal material first nipple joint includes the first external screw thread that the first end of tubulose body and tubulose body surface was equipped with, the first internal thread that second end internal surface was equipped with, the second nipple joint includes second internal thread and third internal thread that tubulose body and the first end of tubulose body and second end internal surface were equipped with respectively, the first end of first nipple joint can pass through screw -thread fit through the third internal thread of first external screw thread and the first end of second nipple joint to be realized being connected, the first internal thread of first nipple joint second end with the second internal thread of second nipple joint second end is used for respectively passing through screw -thread fit with the external screw thread at glass steel oil pipe both ends to be realized being connected. The utility model discloses fundamentally has solved glass steel oil pipe was damaged by the handling instrument easily at the loading and unloading in -process common fault, and small, installation convenient to use can be applicable to various operating modes such as high temperature, high pressure.
Description
Technical field
The utility model relates to oil pipe jointing field, specifically a kind of joint connected for glass fiber reinforced plastic oil pipe.
Background technology
Because glass fiber reinforced plastic oil pipe exists the anticorrosive function such as by force, therefore widely apply in actual oil exploitation, current glass fiber reinforced plastic oil pipe is single directly to be connected by threaded engagement, but in actual motion, glass fiber reinforced plastic oil pipe is generally subject to the External Force Acting of demounting tool in the installation and removal process of workover, cause and certain damage is caused to glass fiber reinforced plastic oil pipe, substantially reduce glass fiber reinforced plastic oil pipe application life.
Utility model content
The purpose of this utility model is exactly the defect existed for prior art, provides a kind of structure simple, easy to use, with low cost and the glass fiber reinforced plastic oil pipe connector that can reuse, solves the outside destroy problem of glass fiber reinforced plastic oil pipe in cargo handling process.
The technical solution of the utility model is: be made up of the first pipe nipple of steel metal material and the second pipe nipple two split assemblies, the first internal thread that described first pipe nipple comprises the first external screw thread that tubular body and tubular body first end external surface be provided with, the second end inner surface is provided with; Described second pipe nipple comprises the second internal thread and the 3rd internal thread that tubular body and tubular body first end and the second end inner surface be respectively equipped with; The first end of described first pipe nipple can realize being connected by threaded engagement with the 3rd internal thread of the second pipe nipple second end by the first external screw thread; First internal thread of described first pipe nipple second end and the second internal thread of described second pipe nipple first end are used for realizing being connected by threaded engagement with the external screw thread at glass fiber reinforced plastic oil pipe two ends respectively.
Such scheme can be improved to further:
Described first external screw thread, the first internal thread, the second internal thread and the 3rd internal thread are tapered thread, and described first external screw thread and the 3rd internal thread can realize conical surface threaded engagement, described first internal thread, the second internal thread can realize conical surface threaded engagement with the external screw thread at glass fiber reinforced plastic oil pipe two ends respectively; Conical surface threaded engagement can improve the sealing effectiveness be threaded.
Internal and external threads in described glass fiber reinforced plastic oil pipe connector all adopts the long screw thread of API standard 8 tooth EUE, and this design can realize being not easy thread alternating in installation and removal process.
The utility model is by being equiped with internal thread and externally threaded pipe nipple in adding respectively of glass fiber reinforced plastic oil pipe two ends, two pipe nipples are threaded connection to coordinate and realize the single connection of glass fiber reinforced plastic oil pipe, and glass fiber reinforced plastic oil pipe connector uses sheet metal material, fundamentally solve the common fault that glass fiber reinforced plastic oil pipe is subject to handling instrument damage in cargo handling process; The utility model volume is little, easy to install, can be applicable to the various operating mode such as high temperature, high pressure.

In figure: 1. the first pipe nipple, 1.1. first pipe nipple tubular body, 1.2. first external screw thread, 1.3. first internal thread, 1.4. transition part, 2. the second pipe nipple, 2.1. second pipe nipple tubular body, 2.2. second internal thread, 2.3. the 3rd internal thread, 3. the first glass fiber reinforced plastic oil pipe, 4. the second glass fiber reinforced plastic oil pipe.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is described further.
With reference to Fig. 1-2, a kind of glass fiber reinforced plastic oil pipe connector, be made up of the first pipe nipple 1 of steel metal material and the second pipe nipple 2 two split assemblies, the first pipe nipple 1 comprises the first internal thread 1.3 that the first external screw thread 1.2, second end inner surface that the first pipe nipple tubular body 1.1 and the first pipe nipple tubular body 1.1 first end external surface be provided with is provided with; Second pipe nipple 2 comprises the second internal thread 2.2 and the 3rd internal thread 2.3 that the second pipe nipple tubular body 2.1 and the second pipe nipple tubular body 2.1 first end and the second end inner surface be respectively equipped with; The first end of the first pipe nipple 1 can realize being connected by threaded engagement with the 3rd internal thread 2.3 of the second pipe nipple 2 second end by the first external screw thread 1.2; First internal thread 1.3 of the first pipe nipple 1 second end and the second internal thread 2.2 of the second pipe nipple 2 first end are for realizing being connected by threaded engagement with the external screw thread at glass fiber reinforced plastic oil pipe two ends respectively.First external screw thread 1.2, first internal thread 1.3, second internal thread 2.2 and the 3rd internal thread 2.3 are tapered thread.Each internal and external threads all preferably adopts the long screw thread of API standard 8 tooth EUE.
Above-mentioned glass fiber reinforced plastic oil pipe connector be used for two ends be externally threaded glass fiber reinforced plastic oil pipe with the use of, concrete using method is see Fig. 3, be connected by conical surface threaded engagement by first internal thread 1.3 of first glass fiber reinforced plastic oil pipe 3 one end external screw thread with the first pipe nipple 1 second end, second glass fiber reinforced plastic oil pipe 4 one end external screw thread is connected by conical surface threaded engagement with the second internal thread 2.2 of the second pipe nipple 2 first end; Then the first pipe nipple 1 first end is realized being connected by conical surface threaded engagement with the 3rd internal thread 2.3 of the second pipe nipple 2 second end by the first external screw thread 1.2, thus two individual glass steel oil pipes couple together.During dismounting, demounting tool only needs to act on glass fiber reinforced plastic oil pipe connector and just adjacent glass fiber reinforced plastic oil pipe can be disassembled, thus fundamentally solves glass fiber reinforced plastic oil pipe in cargo handling process, be subject to the common fault that handling instrument damages.
