Description
Technical Field
The utility model relates to a foam glass technical field specifically is a foam glass structure of low heat conduction.
Background
Foam glass was invented by Pittsburgh Corning, USA, and is an inorganic non-metallic glass material which is prepared by finely crushing cullet, a foaming agent, a modification additive, a foaming promoter and the like, uniformly mixing, melting at high temperature, foaming and annealing.
The foam glass is a light high-strength building material and a decorative material with excellent heat insulation (cold insulation), sound absorption, moisture resistance and fire resistance, the use temperature range is 196 ℃ below zero to 450 ℃, the service life of A-grade non-combustible glass is the same as that of a building, and the moisture permeability coefficient is almost 0; although other novel heat insulation materials are in a variety of layers, the foam glass occupies more and more important positions in the fields of low heat insulation, moisture-proof engineering, sound absorption and the like due to the permanence, safety and high reliability of the foam glass; its production is the reuse of waste solid materials, which is an example of the environmental protection and gaining a great economic interest.
The existing partial foam glass has poor heat insulation performance, so that the effect after use can be directly influenced, the heat conductivity coefficient of an object is connected with various aspects of the object, on one hand, the object is of a structure, and therefore a foam glass structure is provided for realizing the effect of low heat conductivity.
SUMMERY OF THE UTILITY MODEL
Based on this, the present invention provides a foam glass structure with low thermal conductivity to solve the above mentioned technical problems in the background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a foam glass structure of low heat conduction, includes the foam glass body, the terminal surface of foam glass body is seted up flutedly, and the inside of recess is formed with the air cavity, the terminal surface of foam glass body is located the outside of recess and is provided with the extraction opening.
Through adopting above-mentioned technical scheme, all be provided with corresponding structure at the input and the output of steam, play the isolated effect to steam, both realized having realized the cutting off to the heat source, realized blocking heat-conducting again, promoted the low heat conductivility of foam glass body on the whole.
The utility model discloses further set up as, the bottom of recess is connected with the connecting pipe with the air cavity intercommunication.
Through adopting above-mentioned technical scheme, play the effect of the air cavity evacuation of being convenient for.
The utility model discloses further set up to, the heat dam has been seted up to foam glass body's bottom inside, and the internally mounted of heat dam has the tesla valve.
Through adopting above-mentioned technical scheme, just begin to insulate against heat at the hot gas input end, realize one side thermal-insulated effect.
The utility model discloses further set up to, the quantity of tesla valve is the multiunit.
By adopting the technical scheme, the effect of blocking hot air flow is achieved.
To sum up, the utility model discloses mainly have following beneficial effect:
the utility model discloses a recess, the air cavity, extraction opening and tesla valve, before using, it is airtight with the air cavity terminal surface through external sealing material, utilize the extraction opening to the air cavity evacuation afterwards, it is further, the top of whole foam glass body is said again and is carried out airtight maintenance, when the installation, the one end orientation that will have the air cavity need thermal-insulated one end can, concretely, outside heat source can earlier with foam glass body outer wall contact, the existence of tesla valve makes the unable inflow to foam glass body of hot gas of very big part inside this moment, consequently, the thermal-insulated performance that has realized better effect is low thermal conductivity, and partial steam is when conducting to air cavity below, because the inside vacuum that fills of air cavity, consequently, the unable further conduction of its heat, further promotion the thermal-insulated performance that is low thermal conductivity.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.
The following describes an embodiment of the present invention according to its overall structure.
The utility model provides a foam glass structure of low heat conduction, as shown in fig. 1-3, including foam glass body 1, foam glass body 1's terminal surface is seted up flutedly 2, and the inside of recess 2 is formed with air cavity 3, and foam glass body 1's terminal surface is located the outside of recess 2 and is provided with extraction opening 4, and foam glass body 1's bottom is inside to be seted up hot wall chute 5, and hot wall chute 5's internally mounted has tesla valve 6, and tesla valve 6's use has just realized the effect of once thermal-insulated at the hot gas input end.
Referring to fig. 2, the bottom of the groove 2 is connected to a connecting pipe connected to the air chamber 3, which serves to fill the air chamber 3 with vacuum, thereby further isolating heat conduction by using vacuum.
Referring to fig. 3, the number of the tesla valves 6 is plural, and the plural tesla valves 6 block the flow of the hot gas.
The utility model discloses a theory of operation does: before use, the end face of the air cavity 3 is sealed through an external sealing material, then the air cavity 3 is vacuumized through the air exhaust port 4, and further, the top end of the whole foam glass body 1 is sealed and finished;
when the installation, the one end orientation that will have air cavity 3 can the one end that needs thermal-insulated, it is concrete, outside heat source can earlier with the contact of foam glass body 1 outer wall, the existence of tesla valve 6 makes the unable inflow of hot gas of very big part to foam glass body 1 inside this moment, consequently, the thermal-insulated performance that has realized better effect is low heat conductivility promptly, and partial steam is when conducting to air cavity 3 below, because the inside vacuum of filling of air cavity 3, consequently, the unable further conduction of its heat, further promotion heat-insulated performance is low heat conductivility promptly.
