Abstract

The utility model discloses a kind of New Large Caliber steel pipe fittings, it comprises through the pipe fitting matrix be welded or seamless steel pipe fittings is made, the inner and outer surface of pipe fitting matrix is coated with epoxy resin anticorrosive coat, and the pipe end of pipe fitting matrix is provided with O RunddichtringO, and O RunddichtringO outside is provided with polyvinyl plastics layer; The steel of the axial strength that pipe end is fixed with for strengthening pipe end plastics founds rib.Pipe end be wound around polyvinyl plastics, one is in order to compacting seal ring seals, two be in order to large-diameter steel-plastic composite pipe road ancillary engineering facility, adopt existing Electric thermal smelting belt to connect.Pipe end is welded with steel band and founds rib, for strengthening the axial strength of pipe end plastics.The utility model is adopted can effectively to ensure pipe fitting intensity and bearing capacity.

Description

A kind of heavy caliber steel pipe fittings
Technical field
The utility model relates to a kind of New Large Caliber steel pipe fittings.
Background technique
Steel pipe fittings based on known technology generally has steel pipeline elbow, reducing and threeway etc., is mainly used in steel pipeline, and Connecting format is main mainly with welding or Flange joint.When steel pipe fittings is used for Plastic pipeline, general employing Flange joint, this just need to make special pure mould or with framework steel plastic flange plate for the connection with steel pipe fittings, increase cost, when Plastic pipeline adopts joint seal of flanges, due to pipeline body expand with heat and contract with cold by ambient temperature and medium temperature variable effect larger, so flange seal be applied to Plastic pipeline connect and unreliable, As time goes on, the probability that flange seal is revealed will increase, and brings hidden danger to pipeline use safety.The utility model will solve the connection sealing problem of above-mentioned steel pipe fittings and Plastic pipeline.
Model utility content
The technical problems to be solved in the utility model is to provide the heavy caliber steel pipe fittings that a kind of structure is simple, easy to connect, connection sealing is good, for large-diameter steel-plastic composite pipe road ancillary engineering facility.
For realizing above-mentioned technical problem, the technological scheme that the utility model provides is: a kind of heavy caliber steel pipe fittings, its key technology is: it comprises through the pipe fitting matrix be welded or seamless steel pipe fittings is made, the inner and outer surface of described pipe fitting matrix is coated with epoxy resin anticorrosive coat, the pipe end of described pipe fitting matrix is provided with O RunddichtringO, and described O RunddichtringO outside is provided with polyvinyl plastics layer;
The steel of the axial strength that described pipe end is fixed with for strengthening pipe end plastics founds rib.
Preferably, the pipe end of described pipe fitting matrix offers the groove of annular, and described O RunddichtringO is positioned at the groove of this annular.
Preferably, described steel founds rib and is coated in polyvinyl plastics layer, and vertical rib quantity and steel band intensity are determined according to actual conditions.
Adopt the beneficial effect that produces of technique scheme to be: the utility model be welded or seamless steel pipe fittings for pipe fitting matrix; and be provided with O RunddichtringO, polyvinyl plastics layer and steel band at its pipe end and found rib; can effectively ensure pipe fitting intensity and bearing capacity; protection pipe fitting is not easily corroded; wherein pipe end is placed O RunddichtringO and is wound around polyvinyl plastics; can effectively seal pipe port; when with large-diameter steel-plastic composite pipe road ancillary engineering facility; existing Electric thermal smelting belt can be adopted to connect; easy to connect; reliably, cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, 1, pipe fitting matrix, 2, steel band founds rib, 3, O RunddichtringO, 4, polyvinyl plastics layer.
Embodiment
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
See accompanying drawing 1, this heavy caliber steel pipe fittings adopt be welded or seamless steel pipe fittings as pipe fitting matrix 1, to ensure the bearing capacity of pipe fitting.At pipe fitting matrix 1 inner and outer surface spray epoxy, anti-corrosion protection is carried out to pipe fitting matrix.The pipe end of pipe fitting matrix 1 adopts O RunddichtringO 3 to add polyvinyl plastics layer 4 and seals.O RunddichtringO 3 is positioned in annular groove that pipe fitting matrix 1 pipeline offers, is wound around polyethylene tablet at pipe end, forms polyvinyl plastics layer 4, utilize the shrinkage character of polyvinyl plastics to realize compacting to O RunddichtringO 3 and sealing.The pipe end of pipe fitting matrix 1 is welded with steel band and founds rib, and for strengthening the axial strength of pipe end plastics, vertical rib quantity and steel band intensity are determined according to actual conditions.This steel pipe fittings will be used for large-diameter steel-plastic composite pipe road ancillary engineering facility, adopt existing Electric thermal smelting belt to connect.Pipe end polyvinyl plastics width should meet Electric thermal smelting belt welding requirements.
Need polish to polyvinyl plastics layer 4 surface during use, scale removal, adopts Electric thermal smelting belt to be connected with composite metal plastic pipe.This heavy caliber steel pipe fittings can be used for large-diameter steel-plastic composite pipe ancillary engineering facility, be well positioned to meet pressure, anticorrosion, sealing, connection request.
The unspecified part of the utility model belongs to general knowledge as well known to those skilled in the art.To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from the spirit or scope of the invention, can realize in other embodiments.Therefore, the invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
