Background technique
With flourishing for plastic conduit application, pipe diameter is also increasing, and electric melting pipe fittings are connected as pipeline
Important connection type, application are more and more common.Especially on heavy caliber polyethylene pipeline, especially dn315's or more
SDR17 series electric melting pipe fittings, since its relative wall thickness is relatively thin, in welding, the heated expansion outward of pipe fitting is obvious, it will usually make pipe
The outside buckling deformation in both ends welding area of part causes inner melt pressure to decline, influences welding quality.There is part of the manufacturer using gold
Belong to slips, carries out clamping fixed at pipe fitting both ends, prevent it from expanding outward.The metal slips that this kind of scheme uses, clamping side
Formula is single, after welding after pipe fitting softening, can not continue to provide stable external pressure.And since its is relatively bulky, when use
Very not convenient, practicability is had a greatly reduced quality.
Utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is to provide one kind to be used for electric melting pipe fittings
The pressurizing device of welding.
To achieve the above object, the utility model uses following technical scheme:
A kind of pressurizing device for electric melting pipe fittings welding, including one group of rubber air mattress piece, connecting band and booster pump；It is described
Air bag is equipped with inside rubber air mattress piece, outside is that rubber pad wraps up, and side is equipped with air bag gas nozzle, and both ends are respectively equipped with handle；Institute
Booster pump is stated equipped with air gauge and snorkel；The snorkel and air bag gas nozzle are connected with each other；Two neighboring rubber air mattress piece
Handle be connected with each other by connecting band, one group of rubber air mattress piece is joined end to end by connecting band to be matched with electric melting pipe fittings
The outside of circular ring shape, circular ring shape is equipped with belt tensioner.
A kind of pressurizing device for electric melting pipe fittings welding, the belt tensioner include tightening band body and lock,
Tightening band body is joined end to end by lock.
A kind of pressurizing device for electric melting pipe fittings welding, the air bag gas nozzle are equipped with gas nozzle protrusion.
A kind of pressurizing device for electric melting pipe fittings welding, the rubber air mattress piece are at least 2.
A kind of pressurizing device for electric melting pipe fittings welding, rubber air mattress piece both ends are equidistantly equipped with respectively
3 handles.
A kind of pressurizing device for electric melting pipe fittings welding, which is characterized in that the operating pressure of the booster pump
For 0.5MPa.
Compared with prior art, the utility model has the beneficial effects that the present apparatus uses rubber air mattress piece, in electric smelting when welding
Pipe fitting outer wall clamping fixed, is pressurized using booster pump, guarantees the stabilization of welding process with fixed impressed pressure.Electric melting pipe fittings weldering
After connecing softening, the present apparatus can continue to provide stable external pressure to electric melting pipe fittings, pressure of the electric melting pipe fittings due to external stabilization
Power exists,
It melting expansion direction can only be towards tubing direction, without expanding outward, so that electric melting pipe fittings melting charge and tubing
Melting charge syncretizing effect it is more preferable, welding quality is more reliable.The tubing clamping of the suitable different size of the present apparatus, light and handy spirit
It is living, it is easy to use, it is economical and practical.

Specific embodiment
With reference to the accompanying drawings of the specification, the technical solution of the utility model is further described:
As shown in Fig. 1 to 2, a kind of pressurizing device for electric melting pipe fittings welding of the utility model, including three rubber
Air cushion piece 1, connecting band 2 and booster pump 4.Air bag is equipped with inside rubber air mattress piece 1, outside is that rubber pad wraps up, and side is equipped with gas
Capsule gas nozzle 101, both ends, which are respectively equipped with, is equidistantly equipped with three handles 102.Booster pump 4 is equipped with air gauge 401 and snorkel
402.Snorkel 402 and air bag gas nozzle 101 are connected with each other.The handle 102 of two neighboring rubber air mattress piece 1 passes through 2 phase of connecting band
It connects, one group of rubber air mattress piece 1 joins end to end into the circular ring shape matched with electric melting pipe fittings 5 by connecting band 2, circular ring shape
Outside is equipped with belt tensioner 3.Belt tensioner 3 includes tightening band body 301 and lock 302, and tightening band body 301 is first by lock 302
Tail is connected.
Air bag gas nozzle 101 is equipped with gas nozzle protrusion 1001, keeps air bag gas nozzle 101 stronger when connecting with snorkel 401.
