Abstract
The utility model provides an internal bladder for a bearing type plastic electric water heater, which comprises a lower end cover made of plastic, an internal bladder central circle and an upper end cover. The upper end cover and the lower end cover are fixedly connected with the internal bladder central circle through a plurality of locking bolts and nuts; and a plurality of staggered reinforced ribs are injection-molded on the outer surfaces of the lower end cover, the internal bladder central circle and the upper end cover. The locking bolts corresponding to the upper end cover and the lower end cover are connected by reinforced steel rods. The whole internal bladder is matched with the reinforced steel rods and compacting pieces are assembled together by using the locking bolts; the force generated by hot water in the internal bladder and acted on the end covers at two ends is transferred to the reinforced steel rods through the bolts and the compacting pieces on the upper end cover and the lower end cover, thereby enabling the internal bladder to bear a certain amount of pressure, and solving the problem that the plastic internal bladder can not be used for practical production due to the lack of ability to bear.
Description
Technical field
The utility model relates to a kind of inner container of electric water heater, more particularly, relates to a kind of internal plastic container of electric water heater.
Background technology
The inner bag of electric heater is the key of choosing the electric heater quality.The inner bag of electric heater adopts stainless steel metal inner bag or enamel inner container more at present.The pressure-bearing property of this inner bag is better, but exist the insulation and thermal insulation performance not high, corrosion resistance is poor, the problem that service life is short, the cost height and the machine-shaping rate of metal material are not high simultaneously, will use the method for welding in the mill, because the technological problems of welding, the weld electric leakage of leaking easily has a strong impact on the security of use.Though plastics inner bag good insulation preformance, resistance to corrosion is strong, and processing cost is also low, uses lessly, and wherein Zui Da problem is exactly the problem of pressure-bearing.
The utility model content
At the above-mentioned defective that prior art exists, the technical problems to be solved in the utility model provides the strong internal plastic container of electric water heater of a kind of bearing capacity.
The utility model addresses the above problem the scheme that is adopted:
A kind of pressure-bearing type internal plastic container of electric water heater, comprise bottom end cover, inner bag centre circle and upper end cover that plastics are made, end cap and inner bag centre circle are fixedly linked by a plurality of locking screw screw bolt and nuts up and down, and described bottom end cover, inner bag centre circle and upper end cover outer surface are injected with many staggered reinforcements.
Preferably, be connected with the reinforcement steel bar between the described up and down corresponding clamping screw of end cap.
Preferably, be respectively equipped with silica gel sealing ring between described end cap up and down and the inner bag centre circle.
Wherein, described inner bag centre circle single injection-molded is the long tubes of " 8 " font plastics, and the place is divided into two courages by the inner bag partition at " 8 " font centre joint.
Wherein, after the centre joint place of described end cap up and down and inner bag centre circle compresses with loam cake clamping piece and lower cover clamping piece, fix with clamping screw.
Wherein, the centre joint place inner bag partition of described inner bag centre circle is provided with UNICOM's breach up and down.
Wherein, corresponding two courages are respectively equipped with two heating tube mouths of pipe on the described bottom end cover.
Wherein, corresponding two courages are respectively equipped with water inlet pipe mouth and effluent pipe mouth on the described bottom end cover.
The utility model is with respect to the advantage of prior art: the surface of (1) inner bag plastic material is provided with many staggered anyhow reinforcements, and fixing end cap up and down clamping screw be connected with the reinforcement steel bar, greatly strengthened the intensity of plastics inner bags; And whole inner bag cooperates reinforcement steel bar and clamping piece to be assembled together with clamping screw, the power on the end cap of two ends of acting on that allows hot water produces in inner bag, be delivered on the reinforcement steel bar by bolt and upper and lower end cap clamping piece, thereby allow the inner bag can bear certain pressure, before having solved because the plastics inner bag can not pressure-bearing and can not be used for the problem of actual production always.Because whole inner bag is detachable, be convenient in inner bag, install other parts and maintenance simultaneously.(2) inner bag adopts high temperature resistant and low temperature resistant highstrenghtpiston, good insulation preformance, and resistance to corrosion is strong, can bear strong acid, highly basic, and adds with the sealing of silica gel circle, can never leak, and has solved the electric heater seepy question at one stroke.(3) the inner bag centre circle is the long tube of " 8 " font highstrenghtpiston, and the place is divided into two courages by the inner bag partition at " 8 " font centre joint, and the inner bag partition is provided with UNICOM's breach up and down, water circulation in two courages about being convenient to.(4) have two heating mouths of pipe on the bottom end cover, two heating tubes can be installed, two heating tubes can be installed, available this inner bag cooperates specific mixed water valve and control circuit, can produce the storage-type common water heater, also can produce promptly, pre-heated water heater.
