Abstract
Disclosed is a pressure injection-molding fritting concealed pipe connector relating to pipes connection technology. The utility model solve the problem that prior butt-joint rubber gaskets are easy to broke, lax encapsulation leads to infiltration, costs of butt joint are high and the operations of butt joint are complex during the process of installing and using pipes. The pipe connector of the utility model comprises a connecting pipe (2) and an annular fritting glue layer (3). The outer arm axis of the said connecting pipe is provided with two couples of radial fritting glue holes (2-1) in different directions. The fritting glue layer is arranged between the outer surface of the end of the connecting pipe and the connecting pipe. The utility model fills the fritting glue between the pipe and the connecting pipe by way of pressure injection molding and forms the annular fritting glue layer to encapsulate and bond the pipes.
Description
Technical field
The utility model belongs to pipeline connection technology, is specifically related to pressure injection-moulded hot melt sealed pipe joint.
Background technique
The most frequently used in the past pipe joint mainly contains the socket joint rubber sealing and the electric heating fusion welding seals two kinds, the socket joint rubber sealing is because the socket joint sealing rubber ring is ageing-resistant and the erosion performance chemically-resistant solvent is relatively poor, and O-ring seal is subjected to shearing force and damage easily in the installation process, thereby limited its application area; The endoporus undergauge can appear in the counterpart welding of electric heating melting welding, thereby makes pipeline form resistance and cause the flow loss that can't see.Also have that a kind of what be of little use is the socket joint electric heating fusion welding of sweat soldering, it is had relatively high expectations to the processing dimension of pipe fitting bellmouth, if internal diameter junction plane matching gap is excessive, then occurs poorly sealed problem easily, thereby causes seepage; And the pipe fitting cost is higher, welding procedure and equipment more complicated, and is strict to construction environment.
Publication number provides a kind of connecting means of low pressure pipeline for the Chinese patent of CN1150625A, it mainly is to utilize bonding method that its intensity layer and its thermal contractible plastic layer are fixed, can there be bonding not firm problem like this, long-time back coming off owing to the intensity layer, the thermal contractible plastic layer can't be resisted the effect of ambient pressure, thereby lose sealing effect.The Chinese patent of ZL02269217.7 provides a kind of shrink belt to coat the winding steel wire net and has buried ground plastic pipe interface, it adopts multilayer binding type structure, when handling bigbore pipeline butt joint, need increase the number of plies, thereby cause that complicated operation, material increase, cost improves.
The model utility content
Fragile, poorly sealed and cause seepage in order to solve the butt joint cushion rubber that occurs in existing piping erection and the using process, and butt joint cost height, docking operation complicated problems, the utility model provides a kind of pressure injection-moulded hot melt sealed pipe joint.
The pressure injection-moulded hot melt sealed pipe joint of the utility model is made up of connection pipe fitting and heat-fusing glue layer, be provided with at least two pairs of radially melten gel fill orifices at the axial diverse location of the outer wall of described connection pipe fitting place, be solidified with heat-fusing glue layer in the gap between the outer surface of tubing butt end and the described connection pipe fitting internal surface.The utility model is filled between tubing and the connection pipe fitting by above-mentioned fill orifice with the hot melt adhesive that pressure injection-moulded method will melt, the hot melt adhesive that has melted can flow up to the gap that is filled between outer pipe wall and the connection pipe fitting along tube wall, thereby the formation heat-fusing glue layer, so played the double action of sealing and fixed bonding tubing, pipe fitting.
The utlity model has following advantage: 1) employing structure of the present utility model can play reliable sealing and the bonding firm double effects to tubing, pipe fitting interface.2) because the utility model is to adopt the method for pressure hot-melting and injection-molding that sealing material is filled between tubing and the connection pipe fitting, make the gap of tubing and pipe fitting socket joint fitting surface disposable filling with to tamp, thereby make its sealing effect more effective with respect to existing method.3) because hot melt adhesive has better elastic, cementability and very low shrinkage, can seal reliably so can guarantee tubing and pipe fitting.4) because hot melt adhesive also has advantages such as ageing-resistant, resistance to chemical attack, so the utility model has longer service time and bigger application area than the rubber sealing interface, and hot melt adhesive is nuisanceless, can be applied to the transmission of people's domestic water.5) the utility model adopts the hot melt adhesive of unlike material can satisfy the requirements for pipes of carrying all gases and liquid.6) the utility model is simple in structure, cost is low, and easy to operate.
