Detailed description of the invention
This detailed description of the invention provides a kind of plastic cement insulating utensils, and its heat-insulating property is better, and not containing the expanded material with toxin, has good environment protecting.This detailed description of the invention additionally provides a kind of job operation of above-mentioned plastic cement insulating utensils.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection scope of the present invention.
Please refer to Fig. 1, Fig. 1 is the structural representation of plastic cement insulating utensils in the specific embodiment of the invention.
A kind of plastic cement insulating utensils that this detailed description of the invention provides, comprises pipe 12 and plastic cement outer tube 11 in plastic cement, forms vacuum interlayer in plastic cement between pipe 12 and plastic cement outer tube 11.
It should be noted that, plastic cement insulating utensils of the prior art, be all by plastic cement pipe and plastic cement outer tube formation interlayer in filled with foaming material realize effect of heat insulation.Should be appreciated that the transfer mode of heat mainly comprises heat transfer, heat convection and thermal radiation three kinds of forms.Adopt expanded material as thermal insulation material, expanded material still possesses certain heat transfer, and the air of expanded material inside is heat convection also provides condition, therefore, adopts expanded material effect of heat insulation poor; In addition, expanded material contains the toxin to human health, and Long-Time Service has buried potential safety hazard to health.
And the plastic cement insulating utensils that this detailed description of the invention provides, it is heat insulation that interlayer in its plastic cement outer tube 11 and plastic cement between pipe 12 does not adopt expanded material to carry out, but make to form vacuum interlayer therebetween by vacuumizing, heat transfer and heat convection are irrealizable in vacuum environment, and vacuum interlayer has good heat insulation effect.Therefore, the plastic cement insulating utensils that this detailed description of the invention provides has good heat insulation effect, and not containing the expanded material with toxin.
In the preferred version that this detailed description of the invention provides, the tube wall of outer tube is provided with check valve 13, and the Single port of check valve 13 communicates with vacuum interlayer, and another port communicates with the external environment of outer tube; When air in vacuum interlayer is extracted out by check valve 13, check valve 13 is in conducting state.
Setting like this, by check valve 13, the air in vacuum interlayer is extracted out, the sandwich shape in plastic cement between pipe 12 and plastic cement outer tube 11 is made to become vacuum state, vacuumize operation complete after, check valve 13 is by himself function, do not need to take again any seal approach can realize the isolated of vacuum interlayer and outside air, substantially increase the work efficiency of plastic cement insulating utensils.
In addition, check valve 13, relative to the valve of other type, does not have closing process, and therefore, avoid in valve-off process, outside air enters the problem of interlayer, effectively improves the heat-insulating property of plastic cement insulating utensils.
In order to improve the aesthetic property of plastic cement insulating utensils and avoid check valve 13 damaged, check valve 13 can be arranged at the bottom position of plastic cement outer tube 11.Setting like this, the bottom people that check valve 13 is hidden in insulating utensils can not touch check valve 13, avoid the problem of artificial damage, and ensure that the aesthetic property of insulating utensils.
In order to prevent air from entering in vacuum interlayer, in plastic cement, pipe 12 position that is connected with plastic cement outer tube 11 is provided with seal ring 14, and concrete set-up mode can be as described below:
In plastic cement, the open end of pipe 12 can be provided with the annular flap 15 be folded in outside, annular flap 15 is overlapped on the open end of plastic cement outer tube 11, between annular flap 15 and the open end of plastic cement outer tube 11, be provided with the groove of accommodating seal ring 14, seal ring 14 is arranged in groove.When annular flap 15 is pressed in the open end of plastic cement outer tube 11, seal ring 14 produces elastic deformation, makes pipe 12 in plastic cement outer tube 11 and plastic cement realize being tightly connected.
This detailed description of the invention additionally provides a kind of job operation of plastic cement insulating utensils, comprises step:
Processing vacuumize preformed hole, the plastic cement outer tube of insulating utensils processes run through along its thickness direction vacuumize preformed hole;
Assembling, by pipe press-in plastic cement outer tube in plastic cement, in plastic cement outer tube and plastic cement, pipe forms interlayer;
Be tightly connected, pipe and plastic cement outer tube in plastic cement are tightly connected;
Vacuumize, by vacuumizing preformed hole by the interlayer vacuum-pumping in plastic cement between pipe and plastic cement outer tube;
Sealing vacuumizes preformed hole, will vacuumize preformed hole sealing.
According to the job operation of plastic cement insulating utensils provided by the invention, the interlayer between the outer tube of plastic cement insulating utensils and interior pipe does not need to adopt expanded material to carry out heat insulation, makes to form vacuum interlayer therebetween can realize good heat insulation effect by vacuumizing.
Preferably, vacuumize after preformed hole completes in step processing, be also included in and vacuumize mounted valve on preformed hole, the outer wall of valve is tightly connected with the sidewall vacuumizing preformed hole; Vacuumize in preformed hole in step sealing, realize by valve-off the sealing vacuumizing preformed hole.
So, the sealing of vacuum preformed hole does not need the operations such as welding, only needs valve-off, effectively improves work efficiency.
Further, above-mentioned valve can be check valve.Setting like this, by check valve, the air in vacuum interlayer is extracted out, the sandwich shape between inner and outer tubes is made to become vacuum state, vacuumize operation complete after, check valve is by himself function, do not need to take again any seal approach can realize the isolated of vacuum interlayer and outside air, substantially increase the work efficiency of plastic cement insulating utensils.In addition, check valve, relative to the valve of other type, does not have closing process, and therefore, avoid in valve-off process, outside air enters the problem of interlayer, effectively improves the heat-insulating property of plastic cement insulating utensils.
In order to improve, the leak tightness of the vacuum interlayer of plastic cement insulating utensils, during step is tightly connected, by arranging seal ring between pipe and plastic cement outer tube in plastic cement, then by pipe in plastic cement and the welding of plastic cement outer tube.So, effectively improve the leak tightness of the vacuum interlayer of plastic cement insulating utensils.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.Be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the most wide region consistent with principle disclosed herein and features of novelty.
