Water treatment plastic-steel water butt
Technical field
The utility model relates to a kind of water treating equipment, specifically be with a kind of water treating equipment in plastic-steel water butt structurally associated.
Background technology
Pressure pot in some water treating equipment, its pressure pot shell are to be made of the combination of ladle body up and down that metal or plastics are made, and are divided into two-layer up and down, lower floor's ladle body is provided with an inflation inlet, be air chamber, the upper strata ladle body is provided with an intake-outlet, is connected to the water bag in the bucket; Usually this metal ladle body up and down is to adopt the welding process combination, though intensity is high, its weld is exposed to easy oxidation corrosion in the air in using, long its resistance to air loss that then influences of time; And adopt plastic ladle body up and down, though do not have the anxiety of oxidation corrosion, the insufficient strength of plastic material, resistance to pressure is poor.
The utility model content
Therefore, the purpose of this utility model is to provide a kind of intensity height, the good water treatment plastic-steel water butt of resistance to air loss, can overcome the above-mentioned deficiency of commonly using pressure pot.
For achieving the above object, the technical solution of the utility model is such:
A kind of water treatment plastic-steel water butt, first body and the sealing of second body that this water butt shell is made by metal material are formed, this first body is provided with an aeration aperture, second body is provided with an intake-outlet and is communicated to a water storage bag of establishing in second body, and it mainly is: coat a plastic layer in this first body and second external one.
This second inner body wall is in conjunction with the liner glue-line of an environmental protection, and by the mode of a liner steel band with roll forming this liner glue-line and the sealing of water storage bag is incorporated in second body.
Adopt such scheme, because first body and second external one that the utility model is made at metal material coat a plastic layer, by this, can increase the water butt integral intensity and guarantee resistance to air loss, further prolong the work-ing life of water butt, and, guarantee safety of drinking water, health by tap water and metal system water butt shell reliably being separated liner glue-line and cooperating of water storage bag.

Embodiment
As shown in Figure 1, 2, be water treatment plastic-steel water butt of the present utility model, first body 1 and 2 sealings of second body that its water butt shell is made by metal material are formed.
This first body 1 is provided with an aeration aperture 11, after the inflation, makes in first body 1 and forms an air chamber; This second body 2 is provided with an intake-outlet 21 and is communicated to a water storage bag 3 of establishing in second body 2, the utility model special feature is: another body coats a plastic layer 4 outside first body 1 of this metal material and second body 2, and on the inwall of this second body 2 in conjunction with the liner glue-line 5 of an environmental protection, by a liner steel band 6 and second body 2 mode this liner glue- line 5 and 3 sealings of water storage bag are incorporated in second body 2, and this liner glue-line 5 all adopts health level environment-friendly materials to make with water storage bag 3 with roll forming.
When water butt of the present utility model used, water can be entered in the water storage bag 3 by the intake-outlet 21 on this second body 2, open aeration aperture 11 inflations of first body 1 after, under the effect of gaseous tension, the water in the water storage bag 3 can be pushed out intake-outlet 21.
Key of the present utility model is to increase one to coat a plastic layer 4 outside first body 1 that this metal material is made and second body 2, by this, can increase the water butt integral intensity and guarantee resistance to air loss, further prolong the work-ing life of water butt, and, guarantee that tap water can be not contaminated in bucket by tap water and metal system water butt shell reliably being separated liner glue-line 5 and cooperating of water storage bag 3; In addition, water treatment plastic-steel water butt of the present utility model can be made tank arbitrarily at one in a big way by user demand, and to satisfy the use of different occasions, its frame mode is constant.
