Abstract
Tap water distributing system grafted protector for resisting frost crack, it is characterized in that scion grafting has a short section blind pipe on water pipe, hollow or the spongy rubber goods that padding is handled through blowing-up agent in blind pipe, when the water freezing volume in the water pipe expands, the sponge colloid is long-pending by elastic compression in the blind pipe, thereby protects water meter, water valve etc. not by freezing spalling; After freezing to remove, the sandwich rubber elastic return is to larger volume.
Description
The present invention relates to the transportation and distrubution system of material, particularly tap water of liquid existence and the anti-bursting by freezing protective gear of gas transmission and distribution system.
The transmission and distribution pipeline of water, coal gas etc.Gate valve, table tool etc., operating temperature reduce to one delimit after, the stagnant liquid in their vestibules will freeze, the generation volumetric expansion, thereby cause the spalling of transmission ﹠ distribution part.Now commonly used pipeline etc. is imbedded underground, outside it, coat heat insulation layer, or and establish way such as heat supply pipeline, freeze to reach anti-bursting by freezing purpose by stoping intracavity liquid to produce, yet above-mentioned way reliability is not high enough, and water meter, water valve etc. are still more by the situation of bursting by freezing in winter-spring season.
Purpose of the present invention is that a kind of protective gear will be provided, and makes that above-mentioned transmission ﹠ distribution part can be by spalling when its intracavity liquid freezes yet.
The object of the present invention is achieved like this: on part that relates to the liquid distributing system and pipeline, scion grafting one end communicates with the pipeline vestibule, the sealing of one end, but and be filled with the device of the soft packing of volume elastic telescopic at its vestibule liner, do not produce and freeze promptly to depress in the proper functioning in system relating to liquid systems, soft packing relies on itself elasticity to keep larger volume; When system produces when freezing and freezing degree and strengthening gradually, soft packing is compressed by swelling stress effect volume to diminish, and holds the liquid of enduring cold because of solidifying the volume that is increased, thereby avoids the transmission ﹠ distribution part by bursting by freezing.Soft packing can be used the hollow or spongy rubber goods of handling through blowing-up agent, also can select other materials for use.
The present invention because distributing system local as pipeline on scion grafting, so the distributing system running parameter is not had to influence substantially; Simultaneously since the starting point of the present invention lie in and stop in the distributing system liquid to produce to freeze, even and be to freeze also not can bursting by freezing transmission ﹠ distribution part, so the reliability of its anti-bursting by freezing protection is very high; In addition, structure of the present invention is very simple, and cost is also very low.Relating to of usefulness set up apparatus of the present invention and be provided with on the liquid distributing system after, change all very convenient.
The structure of invention is provided by a following embodiment and accompanying drawing thereof.
Fig. 1 is the sectional view of the grafted protector for resisting frost crack of proposition according to the present invention.
The details and the working condition of the anti-bursting by freezing protective gear that proposes according to the present invention are described below in conjunction with Fig. 1.
This device comprises transmission ﹠ distribution pipe (1), three-way union (2), scion grafting cavity (3), padding in cavity (3) but the soft packing (4) of the volume elastic telescopic in the lumen pore, and liquid (5).When the liquid in the transmission ﹠ distribution pipe (5) beginning freezing expansion, soft packing (4) is subjected to the swelling stress effect, and volume is by elastic compression, and protection transmission ﹠ distribution pipes (1) etc. are not by spalling; When freezing to eliminate, soft packing (4) elastic return is to larger volume.
Claims (3)
1, transportation and distrubution system of material, particularly tap water and the gas transmission and distribution system that has liquid to exist; Grafted protector for resisting frost crack; this device comprises transmission ﹠ distribution pipe (1), and three-way union (2) is characterized in that; go up the cavity (3) that scion grafting has end sealing in three-way union (2), at cavity (3) but the lumen pore liner be filled with the soft packing (4) of volume elastic telescopic.
2, install according to claim 1, it is characterized in that cavity (3) scion grafting is on other part of distributing system.
3,, it is characterized in that the hollow or spongy rubber goods of soft packing (4) for handling through blowing-up agent as device as described in the claim 1,2.
