Abstract
The utility model relates to an air extraction device of a vacuum water heater group, which comprises a vacuum valve and a vacuum pump. The structure of the utility model is characterized in that the upper part of a heat exchange pipe of a vacuum cavity of the heater group is provided with an air extraction pipe which is composed of an air extraction main pipe and a plurality of air extraction branch pipes with a plurality of small holes, wherein the air extraction main pipe is connected with the vacuum pump after the air extraction main pipe is welded with the vacuum valve. The utility model has the advantages and the effects of simple structure and simple manufacture, the air extraction efficiency of the vacuum water heater group is enhanced, the content of non-condensable air in the vacuum water heater group is reduced, and the effect of heat exchange of the heater group is enhanced.
Description
Technical field:
The utility model relates to a kind of extract system of vacuum hot water unit, especially at the air extractor of vacuum hot water unit drum internal placement exhaust tube.
Background technology:
At present, traditional vacuum hot water unit inside does not all have the exhaust tube device, its structure as shown in Figure 1, it directly links to each other with rotary-vane vaccum pump 10 with vacuum valve 9; Owing to be full of the medium steam in the vacuum hot-water machine, the interior a small amount of incoagulable gas of the vacuum hot water unit that bleeds is difficult for extracting out, easily makes the vavuum pump oil floatization lose the effect of bleeding with rotary-vane vaccum pump 10 simultaneously, and the time of bleeding is long, damage rotary-vane vaccum pump easily, and can not when unit operation, bleed.
Summary of the invention:
Technical problem to be solved in the utility model provides the air extractor in a kind of vacuum hot water unit that can reduce incoagulable gas content in the vacuum hot water unit.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the air extractor in this vacuum hot water unit, comprise vacuum valve and vavuum pump, its architectural feature is to be provided with exhaust tube on the heat exchanger tube top of unit vacuum chamber, exhaust tube has bleeding of a plurality of apertures by bleed house steward and a Duo Gen and is in charge of and forms, and the house steward that bleeds links to each other with vavuum pump with vacuum valve welding back.
Vavuum pump described in the utility model is the diaphragm type vacuum pump.
Between being in charge of, all adopt house steward of bleeding described in the utility model and drum and bleeding welding.
The utility model compared with prior art has the following advantages and effect: improves the pumping efficiency of vacuum hot water unit, reduced the content of incoagulable gas in the vacuum hot water unit, improved the heat exchange effect of unit, and simultaneously simple in structure, easily make.
Description of drawings:
Fig. 1 is the structural representation of air extractor in the prior art.
Fig. 2 is the structural representation of the utility model embodiment.
The partial schematic diagram of Fig. 3 for bleeding house steward among the utility model embodiment and being in charge of.
Among Fig. 2, Fig. 3: 1, drum, 2, vacuum valve, 3, the diaphragm type vacuum pump, 4, the house steward that bleeds, 5, bleed and be in charge of, 6, heat exchanger, 7, WATER AS FLOW MEDIUM, 8, aperture.
The specific embodiment:
Referring to Fig. 2, Fig. 3, the utility model by drum 1, vacuum valve 2, diaphragm type vacuum pump 3, the house steward 4 that bleeds, bleed and be in charge of 5 and form, top at unit vacuum chamber heat exchanger tube 6 is provided with exhaust tube I, exhaust tube I has bleeding of a plurality of apertures 8 by bleed house steward 4 and a Duo Gen and is in charge of 5 and forms, the house steward 4 that bleeds links to each other with diaphragm type vacuum pump 3 with vacuum valve 2 welding backs, bleed and be in charge of 5, all adopt welding between the house steward 4 that bleeds, vacuum valve 2, bleed also to adopt between house steward 4 and the drum 1 and weld.
Owing to exhaust tube I is set on the top of vacuum chamber heat exchanger tube 6, make a small amount of incoagulable gas that is dispersed in vacuum chamber top be easy to be extracted, the outside diaphragm type vacuum pump 3 that adopts is without pumping fluid, even also can extract incoagulable gas like a cork when unit operation.
Claims (3)
