Abstract
The utility model discloses a load-bearing type double inner container which comprises an outer layer inner container and an inner layer container installed in the outer layer inner container, wherein the inner layer inner container is communicated with a water inlet and a water outlet through a water inlet pipe and a water outlet pipe, and the center of the inner layer inner container is eccentric to the center of the outer layer inner container. The inner layer inner container is opened with an observation hole communicated with the outer layer inner container for facilitating the periodic observation of use conditions of the inner layer inner container and the maintenance, and an anode bar can be further installed on the observation hole, which plays the role of protecting the inner container, reducing corruption and prolonging the service life of the inner container. Circulating medium in the outer layer inner container of the utility model is mutually isolated from usable water in the inner layer inner container, which guarantees the usable water clean, effectively alleviates the generation of scale, and prolongs the service life of the inner container. The outer layer inner container can run with normal pressure or small pressure, which prolongs the service life of the whole inner container.
Description
(1) technical field
The utility model relates to heat accumulation, the technical field of heat exchange devices of heat-exchange systems such as water heater, heating, air-conditioning, the two inner bags of particularly a kind of pressure-bearing type.
(2) background technology
The inner bag of heat-exchange systems such as water heater, heating, air-conditioning is storage, conversion heat and the device that hot water is provided.Now hot-water heating system inner bag on the market has dual mode by whether pressure-bearing is divided, non-bearing type inner bag and pressure-bearing type inner bag.The non-bearing type inner bag, processing is simple, and is with low cost, but can only non-pressure-bearing use, system's instability, the scope of application is very limited.Defectives such as and that the heat accumulation of pressure-bearing type, heat exchange inner bag exist is of a great variety, and mostly cost height, service life are short, easily scaling, water quality vulnerable to pollution, heat exchange effect be undesirable.
(3) summary of the invention
The technical problems to be solved in the utility model has provided the two inner bags of a kind of pressure-bearing type, not only can effectively increase the heat exchange area of system, and make things convenient for cleaning can effectively slow down the generation of incrustation scale, and then prolong its service life.
In order to solve the problems of the technologies described above, the utility model is realized by following measure: the two inner bags of a kind of pressure-bearing type, comprise outer inner bag and the nexine inner bag that is installed in outer inner bag inside, the nexine inner bag is communicated with water inlet and delivery port by water inlet pipe and outlet pipe, and the center of the outer relatively inner bag in the center of described nexine inner bag is eccentric.
The operating position of routine observation nexine inner bag and maintenance for convenience, described nexine inner bag has the peep hole that communicates with outer inner bag, also can go out to install anode stub at peep hole, plays the protection inner bag, reduces corrosion, prolongs inner bag service life.
The two inner bags of pressure-bearing type of the present utility model, wherein said nexine inner bag has the electrical heating reserved opening that communicates with outer inner bag.
The two inner bags of pressure-bearing type of the present utility model have the temperature/pressure relief valve port on the wherein said outer inner bag.
The two inner bags of pressure-bearing type of the present utility model have circulatory mediator inlet and sewage draining exit on the wherein said outer inner bag.
The beneficial effects of the utility model:
1. use water to isolate mutually in circulatory mediator in the outer inner bag and the nexine inner bag, guaranteed to make the water cleaning, the generation that effectively slows down incrustation scale prolongs its service life.Outer inner bag can normal pressure or very little pressure operation, prolongs the service life of whole inner bag.
2. when using, open delivery port, the water inlet is in normally open, the top water running of the utility model pressure-bearing, and the hot water layering is obvious, can provide hot water to greatest extent fast, has guaranteed the stability of system's operation.Reserve peep hole in the utility model, can regularly check its operating position, and as service hatch.
3. enamel inner container can be installed sacrificial anode magnesium rod from peep hole, plays the protection inner bag, reduces the effect in service life of burn into prolongation inner bag.
4. reserve electrical heating mouth and temperature/pressure relief valve port simultaneously, can select as required, convenient and practical.
5. sewage draining exit can conveniently clean inner bag.
(4) description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 looks schematic diagram for the left side of Fig. 1.
1. temperature/pressure safety valve reserved opening, 2. delivery ports, 3. electrical heating reserved opening, 4. water inlets, the 5. circulatory mediators eccentric outer inner bag 9. peep holes 10. circulatory mediators outlet of 6. sewage draining exits, 7. nexine inner bags 8. that enters the mouth among the figure
(5) specific embodiment
The two inner bags of a kind of pressure-bearing type shown in Fig. 1 .2, comprise outer inner bag 8 and the nexine inner bag 7 that is installed in outer inner bag 8 inside, nexine inner bag 7 is communicated with water inlet 4 and delivery port 2 by water inlet pipe and outlet pipe, and the center of the outer relatively inner bag 8 in the center of described nexine inner bag 7 is eccentric.
Described nexine inner bag 7 has the peep hole 9 that communicates with outer inner bag 8.
Described nexine inner bag 7 has the electrical heating reserved opening 3 that communicates with outer inner bag 8.
Have temperature/pressure relief valve port 1 on the described outer inner bag 8.
Have circulatory mediator inlet 5 and sewage draining exit 6 on the described outer inner bag 8, circulatory mediator arrives in the outer inner bag by circulatory mediator inlet 5 during work, siphonage by circulatory mediator is finished heat exchange with the water that makes in the heat transferred nexine inner bag 7, and heat exchange area is big, thermal efficiency height.
