Abstract

A backward-coiled-bucket solar water-tank inner tube, is composed of an inner tube body, a vacuum tube mounting port and a seal ring. The key point is that the vacuum tube mounting port is located at the external surface of the inner tube body, a smooth transition loop is provided at the mounting port wall and the edge flange which can avoid damage or scratching of the seal ring by the burrs on the mounting port owing to rotation during installation of the vacuum tube, thus ensures the utilizing effect of the seal ring, guarantee the service life of the water tank to reach the design requirements, avoids any loss of the customers and installation enterprises of the solar water-heater resulted by this problem.

Description

Oppositely roll up bucket solar water container inner bag

Technical field

The utility model belongs to the manufacturing technology of solar water container inner bag.

Background technology

Solar water heater tank inner container is the vitals that guarantees the hot water effect, against vacuum pipe type solar energy water heater, and its inner-tube structure is even more important, also is the part of relative complex.The vacuum pipe solar water heater inner water tank generally adopts stainless steel material to make.According to the pipe number of the vacuum tube of design and installation, on inner water tank, have the circular mounting mouth of respective numbers.The common disposable piercing and flanging moulding of these installing ports.At oral area a turnup structure is arranged, be used for the sealing ring between cutting ferrule inner bag and vacuum tube.The flange of the installing port of existing vacuum pipe solar water heater inner water tank partly is to be hidden in the gallbladder intracavity, generally is about 30 ° at the flange and the angle between the wall of oral cavity of installing port oral area.Usually can be in the spinning movement during vacuum tube is installed, the flange at 30 ° of angles, make and form a sharper angle between installing port and flange, sealing ring is marked slight crack, use not for a long time, sealing ring is promptly bad to be split, hot water in the inner bag leaks from the vacuum tube wall, cause the heat-insulation layer immersion between inner water tank and outer barrel wall to be expanded, the water tank deformed damaged can not be incubated; Must change, otherwise can not re-use.All bring loss for user and solar water heater installation enterprises.According to estimates, the solar water heater spoilage that causes because of this reason reaches 10%, is no small problem.

Summary of the invention

The purpose of this utility model just provides a kind of solar water container inner bag of reverse volume bucket, makes the spinning movement that vacuum tube is installed, and can not scratch and scratch sealing ring.

Concrete scheme is as follows:

Oppositely volume bucket solar water container inner bag is made of courage body, vacuum tube installing port and sealing ring, and key is that the vacuum tube installing port is in external of courage, and there is the excessive ring of a slyness at installing port wall and flange place, and excessively ring becomes 35 °-85 ° angle with flange.According to such scheme, after the installing port punch forming, opposite with solar water container conventional roll bucket technology again direction rolls into ladle body, at the bottom of the ladle body two-port is installed two buckets of welding, simultaneously good the cigarette seam welding of ladle body, a reverse volume barrel solar water container inner bag.

The installing port that the utility model has the advantages that vacuum tube is in outside the wall of inner container, is in the inner water tank inner chamber with the installing port of prior art and compares, and the feasible process that vacuum tube is installed when the rotation vacuum tube, avoids damaging the sealing ring at inner water tank installing port place.In addition, one by one slick and sly excessive endless belt is arranged between the chamber wall of the flange of installing port and installing port, flange, and angle then is not less than 35 ° of angles again, and the sealing ring that makes cover be stuck in the installing port place can not be mounted the spinning movement of vacuum tube and damage.Guarantee the sealing of solar water container, thereby reached designing requirement the service life that has guaranteed water tank.Avoid the loss of user and solar water heater installation enterprises; Also has the appearance of interests maintenance and leak check problem.

The specific embodiment

Below in conjunction with accompanying drawing, scheme is specified as embodiment of the present utility model.

With reference to Fig. 1,2,3,4, the installing port 3 of solar water heater tank inner container 1 again by particular manufacturing craft punching press flange, is rolled into 35 ° of-85 ° of angles to the oral area end face punching press flange that has burr thorn mouth by the punching press pore-forming, oppositely the volume bucket becomes drum shape again, with fillet 2 welding fabrications.At last the fastening and welding of the bucket ends 4 cutting ferrule at two-port place, barrel-shaped owing to adopt oppositely volume bucket, institute so that vacuum tube 8 installing ports extend outward outside the courage body 1.In the punching press turn-up process, make the chamber wall 9 and 5 of the flange of installing port 3 that an excessive slick and sly endless belt 6 be arranged, in the stamping forming process of installing port, each corner of installing port 3 all is made into arc chord angle, can not be mounted revolving force in the vacuum tube process and scratch to draw and to split so that be fastened in the sealing ring 7 at installing port 3 places.

With reference to Fig. 1,3,4, the shape of installing port 3 is in the outer end of mouth wall 9, and by particular manufacturing craft, outward flanging in the flange forming process, guarantees that flange 5 and 9 on installing port wall have endless belt 6 conducts of a slyness excessive, avoid forming acute angle.Like this, when vacuum tube 8 is installed, rotation come what may, 3 contact sites that a slyness is arranged of sealing ring 7 and installing port, assurance is fastened in sealing ring 7 between installing port 3 oral areas and courage chamber and is not scratched and scratches; Reach designing requirement the service life that has also just guaranteed the sealing property of water tank and sealing ring 7.

Claims

1, oppositely rolls up bucket solar water container inner bag, constitute by courage body (1), vacuum tube installing port (3) and sealing ring (7), it is characterized in that vacuum tube installing port (3) is in courage body (1) outside, installing port wall (9) and flange (5) are located the excessive ring (6) of a slyness.

2, reverse volume bucket solar water container inner bag according to claim 1 is characterized in that excessive ring (6) becomes 35 °-85 ° angle with flange (5).
