Abstract

The utility model relates to a cast iron water jacket of a water heating stove, which belongs to the technical field of civil stoves or ovens. The utility model is used for providing a water jacket for coal stoves, which has the advantages of reasonable structure and good casting manufacturability. The utility model has the technical proposal that the cast iron water jacket of a water heating stove is composed of an upper water jacket and a lower water jacket; a plurality of butted joints which are communicated are uniformly distributed on the butted surface of the upper water jacket and the lower water jacket along the circumference with certain interval, heat-resistant sealing cushions are respectively arranged between each of two butted joints, and the upper water jacket and the lower water jacket are fixed into integration through a connecting and fixing interface or an outer lug. Because the structure of the water jacket is improved by the utility model, when the utility model is cast, the amount of a casting type core head and the area of the core head are increased. Thus, the phenomena of floating core and cold shut can be avoided; so, the casting manufacturability and the casting quality are good, and the waste product rate is low. In addition, a plurality of interfaces which are communicated are arranged between the upper water jacket and the lower water jacket to be favorable for heat exchange in the water jacket to improve the heat efficiency of the water jacket. The utility model can be suitable for various water heating stoves.

Description

Hot-water heating stove cast iron water jacket

Technical field

The utility model relates to a kind of hot-water heating stove cast iron water jacket, particularly a kind ofly is contained in manyly with the cast iron water jacket on the domestic briquet stove, belongs to domestic burners or kitchen range technical field.

Background technology

Commercially available multifunctional water radiator can be cooked for family, heating, bathing and use hot water etc.In adorning a class hot-water heating stove of water jacket cylinder iron, common structure is such, provide the water jacket of heat exchange to form by upper water sleeve and lower water jacket serial connection, the serial connection part is a pipe joint, upper water sleeve is provided with the water outlet interface of hot water, lower water jacket is provided with the water inlet interface of backwater, and its lower water jacket is contained between the refractory layer and heat-insulation layer of burner hearth, and upper water sleeve is looped around the fire door place.The weak point of this type of furnace is that one or two serial connection interface is only arranged between the upper water sleeve of casting and the lower water jacket, like this, when the casting water jacket, the core print of the shaping core of water jacket thorax body is not only few but also little, in casting cycle, no matter be upper water sleeve, or lower water jacket, usually cause waste product, or the even phenomenon of lower wall wall unevenness on the foundry goods occurs because of core drifts about.In addition, the stud place easily produces cold shut on the core, so require tighter to molten iron temperature.Moreover be when cast, the gas in the core is difficult for discharging, and can make the foundry goods upper wall pore occur like this, causes foundry goods to be scrapped.In a word, the water jacket of said structure, casting manufacturability is bad, and tighter to casting technique measure requirement, the casting wasted product rate is higher.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of hot-water heating stove cast iron water jacket, and this jacket structure for water is reasonable, casting manufacturability good, the casting wasted product rate is low.

It is as follows to address the above problem the technical scheme that is adopted:

A kind of hot-water heating stove cast iron water jacket, it is the improvement on former cast iron water jacket basis, it comprises upper water sleeve and lower water jacket, the uniform 3-9 of interface upper edge circle spacing of said upper water sleeve and lower water jacket is communicated with mating interface, be provided with heat-resistant seal gasket between the connection mating interface, upper water sleeve and lower water jacket are fixed together.

Above-mentioned hot-water heating stove cast iron water jacket, said upper water sleeve and lower water jacket are established uniform interface or the engaging lug of being connected and fixed, and are screwed between the two.

Above-mentioned hot-water heating stove cast iron water jacket, said upper water sleeve is communicated with mating interface for three groups of adjacent in twos connection mating interfaces with lower water jacket, is equipped with between two adjacent connection mating interfaces of every group and is connected and fixed interface.

For the further casting manufacturability that improves heating area, improves lower water jacket, above-mentioned hot-water heating stove cast iron water jacket, said lower water jacket adopts and divides body structure, be designed to two parts of upper semi-body and lower semi-body, upper semi-body is provided with the lower semi-body interbody spacer and is communicated with mating interface, be provided with heat-resistant seal gasket between the connection mating interface, be screwed between the engaging lug of upper semi-body and lower semi-body.

Hot-water heating stove cast iron water jacket provided by the utility model, owing to improved the structure of water jacket, can when casting, increase the quantity of core for cast core print and the area of core core print, so can avoid the core floatation phenomenon during casting and produce the cold shut phenomenon, in addition, also help the exhaust of core, so casting manufacturability is good, be easy to grasp, casting quality is good, and percent defective is low.In addition, establish a plurality of connection mating interfaces between the last lower water jacket and also help the interior heat exchange of water jacket, improve the thermal efficiency of water jacket.The utility model can be suitable for various hot-water heating stoves.
