The market accounting of the preceding pipeline of house ornamentation indoors is about 90%, becomes the leading products of indoor hot and cold water pipeline.But PP-R pipeline
Because its glass transition temperature is 2 DEG C or so, therefore, in winter under cryogenic conditions, the toughness of pipeline declines, and shows certain
Brittleness.After water freezing in pipeline, volume becomes larger expansion 10%, and the PP-R under room temperature has certain creep properties, and volume increases
10%, there is slight blow-up in pipeline, but not the phenomenon that destroy.But under cryogenic, PP-R pipeline brittleness is big, pipeline
Once interior water icing volume expands, pipeline just will appear bursting by freezing.
About the antifreeze of PP-R pipe, the generally indoor carry out heating of building in the north supplies, return water is insulated using heating system
Isothermal holding is carried out in advance with antifreeze or pipeline is warmed up.But in southern region, most tubing is based on secretly burying, by wall
The influence of thickness and groove depth, indoor underground pipe are difficult to carry out isothermal holding.The method of solution winter frost crack pipe is at present
Closing, which is registered one's residence, valve or allows pipeline to drip, and keeps water flowing in pipeline, while can discharge pressure.But general pipeline knot
Ice typically occurs at night, and the time can not monitor, and owner is less able to accomplish that closing valve is antifreeze, in recent years winter PP-R pipeline
Booster phenomenon takes place frequently, and brings huge loss to owner.

Specific embodiment
The present invention is further explained in the light of specific embodiments, but the scope of protection of the present invention is not limited thereto.
Embodiment: comparative diagram 1
A kind of interior freeze proof system and device of cycle P P-R pipeline, including for user convey tap water cold water pipe 1 of registering one's residence,
Registering one's residence on cold water pipe 1 of registering one's residence and is connected in parallel in several service pipes 2 registered one's residence on cold water pipe 1 at shut-off valve 101,
It is equipped with overall plastic safety valve 201 on service pipe 2, the water outlet of service pipe 2 is equipped with tap 202, used in the utility model
Overall plastic safety valve 201 structure as disclosed in Patent No. ZL2017203712774.
One end of first pipe and one end of second pipe are connected to and register one's residence on cold water pipe, the first pipe 4
One end far from cold water pipe 1 of registering one's residence is connected with one end far from cold water pipe 1 of registering one's residence of second pipe 5, forms first circulation pipeline,
And service pipe 2 is set on the first circulation pipeline (cold water pipe 1 of registering one's residence, first pipe 4 and the connection formation of second pipe 5
First circulation pipeline)；
Above-mentioned first pipe 4 is equipped with temperature-sensitive solenoid valve 401 and first check-valve 402, and second pipe 5 is equipped with induction and follows
The setting of ring water pump 501 and second check-valve 502(second check-valve 502, the tap water registered one's residence in cold water pipe 1 can not directly into
Enter second pipe 5), when water temperature is higher than 2 DEG C, temperature-sensitive solenoid valve 401 is in close state, in first pipe 4 and second pipe 5
Tap water be in run-stopping status, but do not influence the just common water of user.When the water temperature for cold water pipe 1 of registering one's residence is lower than 2 DEG C, sense
Warm solenoid valve 401 automatically turns on, while incuding water circulating pump 501 and sensing that the signal issued by solenoid valve 1 is started, and will
Water in first pipe 4 is transported to second pipe 5, returns again to cold water pipe 1 of registering one's residence, and realizes that the tap water in first circulation pipeline follows
Circulation moves (i.e. as shown in figure 1, the tap water in first circulation pipeline, circulate along clockwise direction).
The temperature of tap water is lower in order to prevent, even if the water in pipeline is circulated, tap water still can freeze
The problem of, the utility model is connected with third pipeline 3 on second pipe 5, forms second circulation pipeline, and incude water circulating pump
501 are set on the second circulation pipeline；The third pipeline 3 is equipped with third check-valves 301 and heater 302, heater
302 and induction water circulating pump 501 connect with 401 signal of temperature-sensitive solenoid valve, when temperature-sensitive solenoid valve 401 sense water temperature be lower than 2
DEG C when, temperature-sensitive solenoid valve 401, which transmits signal to heater 302 and induction water circulating pump 501, makes its work, incudes water circulating pump
501 when being transported to third pipeline 3 for ice water, and ice water is heated by heater 302, then by third check-valves 301, by
Water circulating pump 501 is incuded by delivery into cold water pipe 1 of registering one's residence, and transient heating (third is carried out to the water in cold water pipe 1 of registering one's residence
Check-valves 301 avoids the tap water in first pipe 4 from flowing directly into third pipeline 3, as shown in figure 1, in second circulation pipeline
Tap water circulates in the counterclockwise direction).When temperature-sensitive solenoid valve 401 senses that water temperature is higher than 2 DEG C, temperature-sensitive solenoid valve 401
It is automatically closed, is simultaneously emitted by signal, induction water circulating pump 501 is also closed.Guarantee that the water temperature registered one's residence in cold water pipe 1 is higher than 2
DEG C, the condition of icing cannot be reached.
Content described in this specification is only to enumerate to inventive concept way of realization, and protection scope of the present invention is not answered
When the concrete form for being seen as limited by embodiment and being stated, protection scope of the present invention is also only in those skilled in the art's root
According to present inventive concept it is conceivable that equivalent technologies mean.
