Abstract
A kind of expansion cracking proof floor heating pipe, including floor heating tube body, several expansion cracking proof devices are equipped in the floor heating tube body, the expansion cracking proof device includes the tubular body being fixed in floor heating pipe inner body wall, the outer diameter of the tubular body is less than the internal diameter of floor heating tube body, the tubular body includes a blind end and an open end, the open end is embedded with a sealing sliding block, spring is equipped in tubular body, one end of the spring is fixed on the blind end of tubular body, other end contact is equipped with sealing ring between the rear end of sliding block, the sealing sliding block and floor heating pipe inner body wall.Several expansion cracking proof devices are added inside the utility model floor heating pipe, prevent that floor heating pipe spalling is extended the service life of floor heating pipe when water build-ups ice in pipe.
Description
Technical field
The utility model is related to a kind of expansion cracking proof floor heating pipes.
Background technology
As the improvement of people's living standards, the use of floor heating is more and more extensive.Water floor heating is one of which,
Refer to that water is heated to certain temperature, is transported to underfloor water pipe pipe radiating network, is generated heat by floor by realize heating purpose
A kind of heating mode.Water floor heating is steadily liked by consumer with its safe radiationless and fever, still, when water floor heating
Heating supply equipment breaks down, when the water in floor heating pipe is not flowed or is not heated, in cold winter, and the water in floor heating pipe
It easily build-ups ice, water volume of build-uping ice becomes larger, and floor heating pipe is easy by ice cube spalling, and for floor heating pipe once rupturing, maintenance cost is high.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of expansion cracking proof floor heating pipe, when the water in floor heating pipe
When freezing and expansion, by floor heating pipe spalling when to prevent that water build-ups ice in pipe, it can be extended by increasing floor heating pipe pipe content product
The service life of floor heating pipe.
Technical solution used by the utility model is：A kind of expansion cracking proof floor heating pipe, including floor heating tube body, the floor heating
Several expansion cracking proof devices are equipped in tube body, the expansion cracking proof device includes the tubulose being fixed in floor heating pipe inner body wall
Body, the outer diameter of the tubular body are less than the internal diameter of floor heating tube body, and the tubular body includes a blind end and an open end, described
Open end is embedded with a sealing sliding block, is equipped with spring in tubular body, one end of the spring is fixed on the blind end of tubular body, separately
One end contact is equipped with sealing ring between the rear end of sliding block, the sealing sliding block and floor heating pipe inner body wall.
Further, along the intrinsic water (flow) direction of floor heating pipe, the blind end of the tubular body is located at the upper of open end
Trip.
Further, the sealing ring is O-ring seal.
Compared with prior art, several expansion cracking proof devices are added inside the utility model floor heating pipe, when the water in floor heating pipe
When freezing and expansion, the sealed end for sealing sliding block toward tubular body can be moved, to increase floor heating pipe pipe content product, be prevented in pipe
By floor heating pipe spalling when water build-ups ice, extend the service life of floor heating pipe.
Description of the drawings
Fig. 1 is the utility model floor heating pipe structural schematic diagram；
Fig. 2 is expansion cracking proof apparatus structure schematic diagram inside the utility model floor heating pipe.
In figure：1- floor heating tube bodies, 2- expansion cracking proof devices, 3- tubular bodies, 4- seal sliding block, 5- springs, 6- sealing rings.
Specific implementation mode
Embodiment below in conjunction with the accompanying drawings is described further the utility model：
As shown in Figure 1, 2, a kind of expansion cracking proof floor heating pipe, including floor heating tube body 1, if being equipped in the floor heating tube body 1
Dry expansion cracking proof device 2, the expansion cracking proof device 2 include the tubular body 3 being fixed on 1 inner wall of floor heating tube body, the tubulose
The outer diameter of body 3 is less than the internal diameter of floor heating tube body 1, and the tubular body 3 includes a blind end and an open end, along floor heating pipe sheet
Water (flow) direction in body 1（Arrow as shown in the figure is water (flow) direction in floor heating pipe）, the blind end of the tubular body 3, which is located at, to be open
The upstream at end is embedded with a sealing sliding block 4 in the open end of the tubular body 3, spring 5, the spring 5 is equipped in tubular body 3
One end be fixed on the blind end of tubular body 3, other end contact is in the rear end of sliding block, the sealing sliding block 4 and floor heating tube body 1
Sealing ring 6 is equipped between inner wall, the sealing ring 6 is O-ring seal.
When water in floor heating pipe normally circulates, sealing sliding block 4 is under the action of floor heating inner pipe water pressure is strong toward the envelope of tubular body 3
Closed end moves, but because of the pressure very little in tubular body 3 at this time, and the rear end for sealing sliding block 4 has the contact of spring 5 to act on, and seals
Sliding block 4 move apart from very little, when the water freezing expansion in floor heating pipe, can will sealing sliding block 4 further toward the close of tubular body 3
Sealing end movement avoids pipeline by spalling to increase floor heating pipe pipe content product, and after ice-out, sealing sliding block 4 is in 5 He of spring
It is resetted under the action of compressed air in tubular body 3.
The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of variation.But it is every without departing from the content of the technical scheme of the utility model, the technology according to the utility model is real
Any simple modification, equivalent variations and remodeling, still fall within the guarantor of technical solutions of the utility model made by confrontation above example
Protect range.
