Abstract

A big-diameter epoxy glass fiber reinforced plastic pipe adaptor comprises a female thread and a male thread arranged at both ends of a glass fiber reinforced plastic pipe. The female thread and the male thread are matched conical threads, and the front end of the male thread is provided with a cylindrical surface with a groove thereon for locating a seal ring. Compared with the prior art, the big-diameter epoxy glass fiber reinforced plastic pipe adaptor adopts conical thread connection and a longitudinal rubber ring for auxiliary sealing, and replaces once sealing into twice sealing which comprises a first seal of rubber ring and a second seal of thread, thereby increasing safety and reliability of joints. The big-diameter epoxy glass fiber reinforced plastic pipe adaptor replaces traditional fine thread into coarse thread, for example, replaces traditional eight teeth per inch into four teeth per inch or two teeth per inch, thereby providing convenience to assembly.

Description

Heavy caliber fiber glass epoxy pipe connector
Technical field
The utility model relates to a kind of, particularly a kind of heavy caliber fiber glass epoxy pipe connector.
Background technique
Usually the epoxy glass steel pipe is divided into two kinds of situations; a kind of is the less epoxy glass steel pipe of bore; also claim high-pressure glass fibre reinforced plastic pipe, high-pressure glass fibre pipe spool; the bore scope is from DN40 to DN200; adopt the long screw thread of API external upset tubing as joint style; a kind of is the bigger epoxy glass steel pipe of bore, and bore generally adopts tapering socket joint bonded joint from DN250 to DN1000.Thread connecting joint epoxy glass steel pipe is easy for installation, joint is reliable, has lot of advantages, but because the restriction of design, production, technology, frock, generally be threaded and be only limited to the pipeline of bore scope from DN40 to DN200, for the pipeline of bore from DN250 to DN1000,, adopt the tapering socket joint bonding because the thread forming difficulty strengthens more.But inconvenience when installing at the scene, joint are not easy to accomplish that sealing is tightly firm.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, proposed a kind of easy for installation, the reliable heavy caliber fiber glass epoxy of joint pipe connector.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of heavy caliber fiber glass epoxy pipe connector, comprise the female thread and the external screw thread that are located at the Glass Steel Tube two ends, be characterized in: described female thread and external screw thread are the tapered thread of working in coordination, be provided with one section cylinder in pin nose, and on cylinder, have the groove of dress seal ring.
The utility model compared with prior art adopts tapered thread to connect, and assists through the cushion rubber auxiliary seal, and once sealing is become twice sealing, and promptly first road is sealed into O-ring seal, and second road is sealed into screw thread, has increased the safety reliability of joint; Can also change original fine thread into coarse thread, change every cun 4 teeth into as original every cun 8 teeth, every cun 2 teeth make installation more convenient.
Description of drawings
Fig. 1 is the structure diagram that female thread and external screw thread are worked in coordination.
Embodiment
A kind of heavy caliber fiber glass epoxy pipe connector, comprise the female thread 1 and the external screw thread 2 that are located at the Glass Steel Tube two ends, described female thread 1 and the tapered thread of external screw thread 2 for working in coordination are provided with one section cylinder in pin nose, and have the groove 3 of dress seal ring on cylinder.The API that its main thread profile comprises standard detains standard thread, every very little 4 button coarse threads, every very little 2 button coarse threads for every cun 8, reaches auxiliary seal cushion rubber in case of necessity.The tooth form of every cun 8 button of API standard thread is screw thread tooth depth 1.808mm, thread spacing 3.175mm, 1 ° of 47 ' 24 " of thread taper.DN250 that this technology is produced and the above specification epoxy Glass Steel Tube that is threaded adopts epoxy resin complex acid anhydride curing agents system moulding and epoxy resin to cooperate the amine curing agent moulding, and the pipeline pressure grade is from 0.6MPa-10MPa, and supporting pipe fitting is complete.Be mainly used in fields such as oil field, chemical industry, potable water.
