Abstract
The utility model provides a pipe connection for plastic and glass steel compound pipe which comprises a connection body, locking sleeves, a nut cover and a sealing gasket, wherein outer circles of one ends of two locking sleeves are provided with male screws, the other ends are provided with radially outward flanges, two ends of the inner hole of the nut cover are provided with female screws, the male screws and the female screws are screwed for connection. The utility model has the advantages of rational design, convenient installation, pipe connection of high rigidity and strength, and reliable sealing performance, can be used for the connection of high, medium and lower pressure pipes, has low cost and corrosion resistance, can overcome the defects arising from the existing connecting mode, and has better social and economical benefits.
Description
The utility model relates to the pipe joint of a kind of plastics and glass fiber reinforced plastic compound tubing.
Now, at oil, chemical industry, in the fields such as water supply and sewage, because frp pipe is compared with metal pipe, have corrosion-resistant, light weight, advantages such as specific strength height and long service life, so its application is more and more wider, and thermoplastic is compared with pure frp pipe with glass fiber reinforced plastic compound tubing, because it is good to have anti-permeability, and more and more paid attention to and welcome by people, but because traditional Placement is unreliable, so the advantage of this composite pipe can not be given full play to, cause its working pressure to be restricted, we can say, the length in the withstand voltage and working life of a pipe-line system depends on the quality of jointing, to a great extent if Placement is bad, tend to cause race, emit, drip, leak phenomenon, thereby the use of traditional Placement is restricted, so reliably and easily Placement is provided, is that to produce this composite pipe desired always.
The purpose of this utility model provides a kind of easy for installation, pipeline coupling stiffness and intensity height, sealing are reliably, can be used for the connection of high, medium and low voltage pipeline, fabricating cost is low, corrosion-resistant, can overcome a kind of plastics of the defective that existing Placement occurs and the pipe joint of glass fiber reinforced plastic compound tubing.
The purpose of this utility model is achieved through the following technical solutions, the pipe joint of a kind of plastics and glass fiber reinforced plastic compound tubing, it is by fittings body, lock sleeve, nut sleeve and sealing gasket are formed, it is radially inner flange and a radially outer flange that two identical metal connector bodies connect end face, fittings body sticks with glue agent it is distinguished glue on the construction layer of compound plastic pipe, the inside liner of two plastic composite pipe ends radially outward is respectively translated into circular, be pressed in respectively on the radially inner flange and end face of metal connector body, one end cylindrical of two lock sleeve has external screw thread, the other end has the radially outward flange, the endoporus two ends of nut sleeve have female thread, and external screw thread screws with female thread and is connected.Its pipe joint useable glass steel is made.
The utility model has the advantages that reasonable in designly, easy for installation, pipeline coupling stiffness and intensity height, sealing are reliable, can be used for the connection of high, medium and low voltage pipeline, fabricating cost is low, corrosion-resistant, can overcome the defective that existing Placement occurs, and has good social, economic benefit.
With reference to the accompanying drawings the utility model is elaborated below.
Fig. 1 is a main TV structure schematic representation of the present utility model;
Fig. 2 is the structural representation of the fittings body 101 among Fig. 1;
Fig. 3 is the structural representation of the lock sleeve 201 among Fig. 1;
Fig. 4 is the structural representation of the nut sleeve 301 among Fig. 1.
The pipe joint of a kind of plastics and glass fiber reinforced plastic compound tubing, it is by fittings body 101, lock sleeve 201, nut sleeve 301 and sealing gasket 401 are formed, the connection end face that it is characterized in that two identical metal connector bodies 101 is radially inner flange 1011 and a radially outer flange 1012, fittings body 101 sticks with glue agent 501 it is distinguished glue on the construction layer 20 of compound plastic pipe, the inside liner 10 of two plastic composite pipe ends radially outward is respectively translated into circular, be pressed in respectively on the radially inner flange 1011 and end face 1013 of metal connector body 101, one end cylindrical of two lock sleeve 201 has external screw thread 2011, the other end has radially outward flange 2012, the endoporus two ends of nut sleeve 301 have female thread 3011, and external screw thread 2011 screws with female thread 3011 and is connected.Pipe joint useable glass steel of the present utility model is made.
When piping erection connects, pack in the nut sleeve 301 in the two ends that the processing of two tubing is had a fittings body 101, between fittings body 101 and nut sleeve 301, sealing gasket 401 is installed, lock with female thread 3011 mating male threads 2011 that have with nut sleeve 301 then, lock sleeve 201 is locked among the nut sleeve 301, thereby realizes the tubing purpose of connecting.
