Abstract
The invention discloses a device for preventing a building inlet pipe from being frozen in winter. The device comprises the inlet pipe, a by-pass pipe, compensators, a valve, a water meter, a water drain opening and a water metal well. The compensators are arranged on the front side and the rear side of a valve on the inlet pipe in the water meter well. The pipe compensators can be flexible pipe fittings capable of effectively relieving the condensation effect of a pipeline, for example, corrugated pipes and flexible connectors, and accordingly the pipeline is prevented from being frost-cracked due to freezing.
Description
Technical field
The present invention relates to pipe control technical field, specifically a kind of winter building introduce pipe defroster.
Background technology
At present, in the winter of cold weather, with the drastically decline of temperature, the phenomenon that pipe occurs shrinkage is introduced, therefore
Introducing pipe often occurs by the phenomenon of bursting by freezing, especially when cold wave arrives, introduce pipe and even more seen repeatly by the situation of bursting by freezing
Not fresh.
In order to tackle this kind of problem, existing technology mostly just relies on water meter chamber simply antifreeze to carry out to introducing pipe
Cold-proof protection, for present construction, directly neglects for the considerably less or even present construction of the antifreezing measures of building introducing pipe
Antifreeze cold-proof protection slightly to introducing pipe.For -15 DEG C of areas are less than for the environment of sudden temperature drop, especially winter temperature,
The ability to bear of pipeline is not allowed, so causing the bursting by freezing of large batch of pipeline and water meter.Therefore, it is necessary to provide one kind
The winter building safe and simple, frost-cracking-preventing effect is good introduces pipe defroster.
Content of the invention
It is an object of the invention to provide a kind of winter building introduces the antifreeze device of pipe, solve to ask present in prior art
Topic.
The technical solution adopted in the present invention is that a kind of winter building introduces pipe defroster, including introducing pipe, bypass
Pipe, compensator, valve, water meter, discharge opening and water meter chamber, it is characterised in that valve (2) are arranged in water meter chamber (6) and draw
Enter the both sides in front and back of the upper water meter (3) of pipe (5), compensator is arranged on the both sides in front and back of valve (2).When building does not allow to cut off the water supply
When, in water meter chamber (6), preferably set bypass pipe (7).
As the further scheme of the present invention：Described compensator (1) is connected with pipe (5) is introduced using ring flange (11).
As the further scheme of the present invention：Flexible pipe (72), such as corrugated tube or flexibility is adopted in compensator (7)
Joint, its length is calculated by winter temperature change (temperature is at -15 DEG C -5 DEG C) and is got.
The invention has the beneficial effects as follows, a kind of winter building introduces pipe defroster, by introducing in water meter chamber
Before and after valve on pipe, both sides arrange compensator, it is to avoid the phenomenon of frost crack pipe occurs, energy-conserving and environment-protective, simple and fast, convenient dimension
Repair.
Description of the drawings
Fig. 1 is the structure chart that a kind of winter building of the present invention introduces pipe defroster.
Fig. 2 is the structure chart that a kind of winter building of the present invention introduces pipe (setting bypass pipe) defroster.
Fig. 3 is the partial enlarged drawing that a kind of winter building of the present invention introduces the antifreeze compensator of pipe.
In figure：1 compensator, 11 flange terminal pads, 12 corrugated tubes or flexible joint, 2 valves, 3 water meters,
4 discharge openings, 5 introduce pipe, 6 water meter chambers, 7 bypass pipes.
Specific embodiment
In order that present disclosure is easier to be clearly understood, below in conjunction with the accompanying drawings the present invention is made furtherly
Bright.
The present invention introduces pipe defroster for a kind of winter building, including introducing pipe, bypass pipe, compensator, valve, water
Table, discharge opening and water meter chamber, it is characterised in that valve (2) are arranged in water meter chamber (6) and introduce the upper water meter (3) of pipe (5)
Both sides in front and back, compensator be arranged on valve (2) before and after both sides.When building does not allow to cut off the water supply, preferably set in water meter chamber (6)
Bypass pipe (7).
Described compensator (1) is connected with pipe (5) is introduced using ring flange (11).
Flexible pipe (72), such as corrugated tube or flexible joint is adopted in compensator (3), and its length passes through winter temperature
Change (temperature is at -15 DEG C -5 DEG C) is calculated and is got.
The principle of the present invention：When introduce pipe local environment sharp temperature drop, winter minimum temperature with -15 DEG C as boundary,
The shrinkage phenomenon that introducing pipe is caused by temperature is inevitable, it is therefore desirable to arrange compensator to compensate.Compensator
Setting is a very important part in defroster, the setting of compensator and the stroke of pipeline, linear expansion coefficient etc. because
Have pass.Linear expansion coefficient refers to due to when ambient temperature, pressure (referring mainly to temperature) change, the linear dimension of object with temperature,
The rate of change of pressure (referring mainly to temperature).
A kind of winter building introduces pipe defroster, and before and after introducing the valve on pipe in water meter chamber, both sides arrange benefit
Device is repaid, the pipeline that this when, straight line was installed using the computing formula of stroke should be：
Δ L=a (t1-t2)L
A thermal coefficient of expansion, the thermal coefficient of expansion of steel pipe is 1.2*10-5/ DEG C；
T1 is medium temperature during conduit running, DEG C；
Temperature during t2 Pipe installing, DEG C.
Pipeline compensator can effectively alleviate the flexible pipe of pipeline shrinkage effect using having, and such as corrugated tube or flexibility connects
Head, so as to avoid pipeline bursting by freezing because of icing, has a safety feature, simple and fast, be easy to maintenance.
FlexbleJoint is also known as expansion bellow or bellow-type expansion joint, refers to containing one or more corrugated tubes, in order to compensate pipe
Line, pipeline or container produce the various devices of change in size by the reason such as expanding with heat and contract with cold.
Flexible joint is the adapter with flexible effect, is generally divided into steel flexible joint and rubber mass flexible joint two
Class.Rubber flexible joint be for play between metallic conduit flexible connection effect hollow rubber product, it is possible to decrease shake and make an uproar
Sound, and can be to the redeeming of expanding with heat and contract with cold that causes because of temperature change.
Compensator is arranged in water meter chamber the present invention both sides in front and back for introducing the upper valve of pipe, can slow down significantly winter room
Outer temperature is not less than -15 DEG C of regional introducing pipe bursting by freezing phenomenons to be occurred, and is that winter building introducing the antifreeze of pipe brings new solution
Certainly thinking and method, simple and fast, convenient keep in repair.
