Abstract

The utility model relates to a barrel for keeping beer fresh with a vacuum insulating layer, which has an improved structure. An upper valve seat is arranged above a barrel body, and a connecting pipe which is led out of the bottom of an inner liner is arranged below the barrel body. The outlet of the connecting pipe is connected with a lower valve seat on which a beer filling and beer discharging valve is arranged. Hollow interlayer space is formed between the stainless steel inner liner and a metal outer liner, and an air sucking opening is connected with the outer liner. A supporting ring which is arranged below the barrel body supports the barrel body. The outside of the outer liner is coated with an outer protective layer which is made of polyurethane foaming materials capable of automatic skin formation. The utility model has the advantages of simple structure, good heat insulating effect, good effect on keeping the beer fresh, and long service life.

Description

Vacuum heat-insulating layer beer refreshing bucket

The utility model relate to a kind of structural development beer-preserving container, be a kind of vacuum heat-insulating layer beer refreshing bucket specifically.

The heat-insulation layer of existing beer refreshing bucket is to add one deck foaming of hard bubbling to reach the heat preserving antistaling effect between inner bag and shell.Heat-insulation layer is very thick, makes barrel of beer bulky, and makes trouble; Because inner bag and shell are plastics and make, shell is frangible, and the easily aging crack of inner bag with the wine heat-insulation layer that bleeds, makes heat-insulation layer lose insulation effect.

The utility model purpose is to overcome the shortcoming in the above-mentioned technology, proposes a kind of vacuum heat-insulating layer beer refreshing bucket, and volume is reduced relatively, high insulating effect, and adopt stainless steel inner container, increase the service life.

The utility model purpose is realized by following technical scheme: this vacuum heat-insulation layer beer refreshing bucket, a upper valve base is arranged above staving, below staving, draw a connection pipe from the inner bag bottom, the connection pipe outlet is connected to and is used to install the lower valve base of irritating wine, going out the wine valve, outside stainless steel inner container and metal, be the hollow interlayer space between the courage, be connected with the gas port of finding time on the courage outside.

Bucket makes the below have carrier ring to hold staving, and outer courage outside is surrounded by the external protection of one deck polyurethane from the foam material.Below staving with the carrier ring of holding staving be nylon material make circular, one circular hole is arranged on the side of carrier ring, connection pipe stretches out from circular hole, the connection pipe end is connected with lower valve base, on lower valve base, install to irritate wine, go out the wine valve, from irritating wine, going out the wine valve and in inner bag, pour into beer or emit beer.The gas port link span copper pipe of finding time of courage bottom welds the air sealed after being vacuumized in the mezzanine space between inner bag, the outer courage outside.Vacuum between inner bag, the outer courage, heat-blocking action is good, to the beer of splendid attire in the inner bag, can keep low temperature for a long time, and fresh keeping time is long.Copper pipe is softer, and after vacuumizing, copper pipe clamps easily, welds good sealing effect.At the external protection that the exterior polyurethane of staving is made from the foam material, specious, decoration function is arranged, because this material is flexible, external courage, inner bag have to subtract and help and protective effect when collision.The metallic ring stiffener, gives and places this position earlier in foam material foaming process at polyurethane, can be consolidated with external protection, installs when lifting the handle of usefulness on staving, can strengthen the intensity at this place.

The advantage of vacuum heat-insulating layer beer refreshing bucket is because vacuum interlayer insulation effect between inner bag, outer courage is good, makes that adorn the beer refreshing time in the inner bag long, barrel volume put foam material with polyurethane relatively to make the staving of thermal insulation layer littler.Stainless steel inner container can corrosion and is aging, long service life.

Embodiment of accompanying drawings.

Fig. 1 is a vacuum heat-insulating layer barrel of beer constructional drawing:

A upper valve base (1) is arranged above staving, exhaust is used in the staving below and draws a connection pipe (9) from the inner bag bottom when being used as Butterworth Hatch and irritating wine, connection pipe (9) outlet is connected to a lower valve base (7), irritate wine, go out the wine valve and be installed on the lower valve base, between the outer courage (4) of stainless steel inner container (5) and metal is hollow mezzanine space, courage (5) the bottom gas port (8) of finding time finds time to connect copper pipe (10) under the gas port outside, is used for taking out inner bag and the interbedded air of outer courage.When take out or vacuum after, copper pipe is clamped, weld sealing, keep the vacuum of inner bag (5) and outer courage (4) intermediate course.There is carrier ring (6) the staving below, and carrier ring (6) side is porose, and connection pipe (9) bends towards a side from the staving bottom, stretches out from the hole of carrier ring (6) side, and outer courage outside is surrounded by the external protection (3) of one deck polyurethane from the foam material of binding up one's hair.There is a ring stiffener (2) to gain in strength on protective cover (3) top.External protection (3) makes vacuum heat-insulating layer beer refreshing bucket both attractive in appearance, can prevent that again collision from causing damage, has protective effect to staving.

Claims

1, a kind of vacuum heat-insulating layer beer refreshing bucket, a upper valve base is arranged above staving, below staving, draw a connection pipe from the inner bag bottom, the connection pipe outlet is connected to and is used to install the lower valve base of irritating wine, going out the wine valve, it is characterized in that outside stainless steel inner container and metal it being hollow mezzanine space between the courage, the gas port of finding time on the courage outside.
