Description
Technical field
The present invention relates to the expansion compensation device field of pipeline, specially a kind of plastic spherical compensator and its manufacturer
Method.
Background technology
Pipeline expansion joint, using playing a part of absorbing heat expansion with compensating shrinkage, is done with metal light wall pipe for a long time in pipeline
Metal bellows telescopic joint use into continuous multiple corrugated sheets superposition compositions is done more, and next is fabricated to more using elastomeric material
The rubber tube telescopic joint of individual spherical shape assembly.
Metal bellows telescopic joint is assembled on metal piping system and used, thin-wall corrugated tube with mechanical performance, compared with
The more ball telescopic joints of rubber tube of low mechanical performance can absorb in metal piping system heat expansion and contraction or compensate metal
Pipeline length change caused by the temperature difference；Metal bellows telescopic joint is assembled on plastics and its compound pipeline complex pipeline system and used,
The plastic conduit of relatively low mechanical performance can not promote or stretch the thin-wall corrugated tube of high-mechanical property, cause metal bellows to stretch
Section can not absorb or compensate plastic conduit length change caused by the temperature difference；By the more ball telescopic joints of rubber tube be assembled in plastics and its
Used in multiport system, because the more ball telescopic joints of rubber tube with plastics and its multiple tube belong to material of different nature, Zhi Nengtong
Cross flange and socket mode and connect, either elastomeric material or flange socket mode interface, can not all be satisfied with direct-burried plastics and
Its compound pipeline complex pipeline system is to long-term and heat-resisting requirement.
In summary, existing metal bellows telescopic joint, rubber multi-ball telescopic joint can not all be satisfied with plastics and its answer
Close the requirement that pipe expands with heat and contract with cold because the temperature difference causes.
The content of the invention
The defects of in order to overcome prior art, there is provided a kind of high mechanical strength, strong adaptability, the pipeline of service life length are mended
Device is repaid, the invention discloses a kind of plastic spherical compensator and its manufacture method.
The present invention reaches goal of the invention by following technical solution：
A kind of ball joint compensator, including straight length, it is characterized in that：Also include spheroid expansion piece and welding section, straight length, spheroid are swollen
The middle part of this three of swollen part and welding section is all penetrated, spheroid expansion piece at least three, and straight length and spheroid expansion piece are staggeredly set
Put, i.e., connected between adjacent two spheroid expansion pieces with straight-run of pipe section, positioned at outermost end two spheroid expansion pieces it is outer
One section of welding section is fixed at end respectively.
The manufacture method of described ball joint compensator, it is characterized in that：Wire netting, Huo Zherong are wound on the lateral wall of welding section
Connect section and be embedded in wire netting；Wire netting melts the welding section at both ends and the interface of the plastic tube of connection after electric smelting or Electromagnetic Heating
It is integrated, the plastic tube of the present embodiment of interface after cooling and connection forms the pipe-line system with Telescopic.
The manufacture method of described ball joint compensator, the interlude of plastic straighttube is integrally uniformly heated to melting temperature
Afterwards, then by the pipeline section of heating compression molding on vacuum mold press is moved to, comprised the following steps that：
A. whole section of plastic straighttube is sent into baking oven, the interlude of plastic straighttube is heated to the melting temperature of plastics in baking oven
Degree；
B. heated plastic straighttube is taken out to be sent on the molding platform of vacuum mold press；
C. the set of molds that the molding platform of vacuum mold press is provided with and straight length and spheroid expansion piece match, and straight tube
The set of molds that matches of section is all made up of setting symmetrical above and below for two moulds of semi-cylindrical, and spheroid expansion piece matches
Set of molds is all made up of setting symmetrical above and below for hemispheric two moulds, is all connected and is evacuated by appendix per mold group
Machine, matched moulds；
D. to implement pumping to the set of molds after matched moulds one by one to the order on both sides successively from middle, under atmospheric pressure,
By distending and the inwall of each mould is clung in the plastic straighttube of molten condition, so as to form straight length and spheroid expansion piece；
E. the quenching into plastic tube, and the plastic tube of shaping is shaped；
F. opening mold group, the plastic tube after cooling, sizing is taken out.
For the present invention in use, being connected serially to by the welding section at both ends in the plastic tube of connection, spheroid expansion piece plays compensation modeling
The effect that expects pipe expands and shunk because caused by expanding with heat and contract with cold.
The present invention realizes the requirement of plastics and its compound pipeline complex pipeline to expanding with heat and contract with cold with the following method：
First, the moderate plastic tube of mechanical performance or plastic composite pipe material are employed to make ball joint compensator, plastics or
Plastic composite can change its modulus of elasticity as the change of temperature is consistent with the plastic conduit connected, bullet consistent with pipeline
Property the compensator of modulus its intensity can be satisfied with the requirement that plastic conduit promotes deformation.
2nd, by being connected to multiple spherical short tubes, the deformation power for variation length that plastic conduit is expanded with heat and contract with cold, with the arm of force
Force spherical to produce deformation in the middle part of push-and-pull spherical direct with torque form, absorb and mend by the deformation of multiple sphericals
The change that the temperature difference causes flow development length is repaid, plays a part of compensator effect.
The beneficial effects of the invention are as follows：High mechanical strength, strong adaptability, service life length.
