Abstract
The utility model discloses a casting iron energy saving water heater. The center of a box body is provided with a cylindrical inner sleeve; the upper side of the box body is provided with a water outlet, and the lower side is provided with a water inlet and a drain outlet; a sand-casting preformed hole for casting is provided with internal threads and then is sealed by bolt bulkheads. The utility model has the advantages of simple product structure, low cost, corrosion resistance and long service life. The utility model thoroughly improves the phenomenon of disassembling a cooking range because of the leakage caused by welding and using a pad in the processing and installing technique.
Description
The utility model relates to a kind of energy-saving water heater, a kind of specifically supporting being installed on the life coal stove, the boiler that utilizes the waste heat of coal stove to heat.
At present, the various energy saving hot water tanks of selling on the market mostly use steel plate by design size through the cutting, be welded, although handle through the whole bag of tricks on the water tank of these welding surface, but often the corrosion owing to incrustation scale causes seepage in this rule weld seam, influenced normal use, the cast iron flush cistern of casting is because casting gate on the make is to adopt cover closure, and the anti-leakage pad that uses between cover plate and the casing mostly adopts rubber, asbestos material to make.And these packings in use also reach the seepage that distortion still causes water tank because of it is aging, and influence is used normally.
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of long service life is provided, and cost is low, not the energy-saving water heater of easy to leak.
Scheme of the present utility model is made up of casing, interior cover, entery and delivery port and reservation screw etc., its design feature is overlapped in cylindrical for being provided with at the center of casing, the top of casing is provided with delivery port, the below is provided with water inlet and sewage draining exit, the bottom of water heater is provided with the founding preformed hole, be shaped on internal thread on the preformed hole, preformed hole silently seals with bolt.
The utility model has the advantages that simple in structurely, cost is low, and is corrosion-resistant, easy to leak not, long service life.
