Abstract
The utility model relates to a flat plate back-pressing type electric melting flange pipe part with a framework, which comprises a covered wire, two wiring pillars, a plastic body and a metal framework. One end of the plastic body is a flange end, and the other end is an electric melting sleeve end which is embedded with the covered wire; the plastic body is embedded with the metal framework; and a plurality of bolt holes are distributed at the flange end surface of the plastic body. The electric melting flange pipe part adopts the metal framework as reinforcement, so that the product bearing level and temperature resistant performance can be matched with the pipe part with the framework. The utility model provides a reliable method for connection between the steel-plastic composite pipe and equipment or a valve and the like. Compared with the original connection method, the reliable method has the characteristics of low cost and convenient installation. The bolt holes on the flange end are formed in one time in the injection-molding process without subsequent processing.
Description
Technical field
The utility model relates to a kind of dull and stereotyped back pressure type band skeleton electric smelting flanged fitting, belongs to technical field of plastic.
Background technique
In the use of the multiple tube of steel skeleton plastic clad pipe one class, generally adopt the mode of flanged joint to be connected with valve with equipment.The attachment portion of composite pipe comprises a plastics flange head, a flange plate and a pair of divided ring.This structure in use makes the plastics flange head be subjected to the extruding component to the tubing center of metal pair open loop easily, and flange seal was lost efficacy, and causes leakage.The 2nd, because flanged joint partly is the pure structure of moulding, voltage withstand class is lower, and heat resistance is bad, and Applicable scope is less.In addition, in the process pipelines construction, single-ended flange flange connecting short tube is essential, present way is the flange short tube that the fixed length pipe is allotted some, but because dimensional problem, such short tube of every basically connection just need carry out once on-the-spot disconnected pipe, this just needs to increase an electric smelting sleeve, like this, required material is more, and cost is higher.In order to overcome the above problems, design a kind of dull and stereotyped back pressure type band skeleton electric smelting flanged fitting, its structure is that an end is a flanged joint, and an end is the electric smelting sleeve of embedded covering thread, and embedded one is welded into whole metal enhancing skeleton in plastics.This electric smelting flanged fitting is used for replacing present flange short tube Placement.An electric smelting flanged fitting is equivalent to a flange short tube, a pair of divided ring and an electric smelting sleeve.
The model utility content
Technology of the present utility model is dealt with problems and is: overcome the deficiencies in the prior art, a kind of dull and stereotyped back pressure type band skeleton electric smelting flanged fitting that needs can also reduce cost that is connected that can satisfy steel-plastic composite pipe and equipment or valve is provided.
Technical solution of the present utility model is: dull and stereotyped back pressure type band skeleton electric smelting flanged fitting, comprise covering thread, two wiring terminals, plastics and metal frames, plastics one end is a flange end, one end is the electric smelting sleeve of embedded covering thread, plastics embedded metal skeleton, the flange end end face of plastics is distributed with some bolts hole.
Described metal frame comprises electric smelting end skeleton flange end skeleton and location steel nail composition, and electric smelting end skeleton and flange end skeleton weld together, and the location steel nail is evenly distributed on the end face of flange end skeleton and electric smelting end skeleton welding ends.
Described covering thread surface soldered has wide welding rod bridge, wide welding rod pipe nipple, wide welding rod and horizontal wide welding rod, horizontal wide welding rod is welded at the place at the coiling last lap, the adjacent horizontal wide welding rod top welding obliquely of wide welding rod bridge, terminal covering thread is guided to downside wiring terminal place along wide welding rod bridge, be connected with the downside wiring terminal, again with some wide welding rod pipe nipple welding fixation ends covering threads, at the some wide welding rods of shaping die " ten " word running channel position transverse weld.
Described wiring terminal is embedded in the electric smelting socket end of plastics.
The utility model compared with prior art beneficial effect is:
(1) the utility model adopts metal frame as strengthening body, and the pressure-bearing grade of product and the tubing of heat resistance and band skeleton are partly mated.
(2) the utility model provides the Placement of a kind of reliable steel-plastic composite pipe and equipment or valve etc.
(3) the utility model is compared with original Placement, and cost is low, and is easy for installation.
(4) the bolt hole once-through in injection moulding process on the utility model product flange end need not following process.
