Abstract
The utility model discloses a water pipe joint of a water heater, which comprises a water outlet joint, a nut of the water outlet joint, a spacing ring, a water outlet pipe, a joint and a connecting nut, and is characterized in that the joint is connected with the water outlet pipe in a way of seal welding; the connecting nut is connected with the water outlet joint by screw thread; the spacing ring is welded at the inner side of a tank body; and the water outlet joint is fastened on the tank body by the nut of the water outlet joint. The traditional end surface sealing is changed into radial sealing, and two seals including an O-shaped sealing ring and a conical-column-shaped press sleeve are arranged, so that the sealing performance of the water pipe joint of the water heater is effectively improved, and the requirement for the axial mounting size of the water outlet pipe can be greatly reduced.
Description
Technical field
The utility model relates to a kind of electromagnet water heater water pipe head new construction, belongs to electromagnet water heater manufacturing technology field.
Background technology
The water route part of electromagnet water heater mainly is made up of institutes such as cartridge heater, jointing, water pipes.Characteristics such as water pipe is the connector of each several part, is generally the tubule class, and needs spatial placement, and that this type water pipe has is in light weight, poor rigidity, intensity are low; Therefore, water pipe must guarantee its reasonable stress in connection procedure; Must not bear bigger extra load, water pipe stretches, distortion otherwise make easily, cracks and make adjacent joint poor sealing; Cause drainage,, more bather's personal safety is produced hidden danger like the water power contact.Fig. 1 is the structural representation of the electromagnet water heater water route part of common usefulness.It mainly is made up of cartridge heater 1, water inlet pipe 2, casing 3, collar nut 4, water out adapter nut 5, spacing ring 6, water out adapter 7, sealing gasket 8, joint 9, outlet pipe 10.Outlet pipe 10 is welded together with joint 9, and weld seam is water-tight; Spacing ring 6 is welded on the box inside face, and water out adapter 7 cooperates through the hexagonal axis hole with spacing ring 6, tightens water out adapter nut 5, and the step end face of water out adapter 7 is close on the medial surface of casing 3.Though this cartridge heater titting water outlet structural design is simple, require the axial dimension of water pipe very accurate, though 4 installing plates of cartridge heater 1 all are provided with long slot bore, can only adapt to the position of Inlet and outlet water one end water pipe.Behind the position of satisfying water inlet pipe 2, outlet pipe 10 end faces can not be fitted with water out adapter 7 end faces after loading onto sealing gasket 8 sometimes well.After forcing fastening nut 4, can make water pipe 10 receive extra additional force.Influence the service life of water pipe 10.If not fastening nut 4 makes sealing gasket 8 places produce drainage again easily.
Summary of the invention
In view of the problem of above-mentioned existence, the purpose of the utility model provides a kind of rational in infrastructure, simple installation, dependable performance, water heater conduit's joint safe in utilization.
For realizing above-mentioned purpose, the utility model has been taked following technical scheme:
The described a kind of water heater conduit's joint of the utility model is made up of water out adapter, water out adapter nut, spacing ring, outlet pipe, joint, attaching nut, it is characterized in that joint and outlet pipe are sealing and are welded to connect; Attaching nut and water out adapter are threaded; Spacing ring is welded in the inboard of casing, and water out adapter is fastened on the casing through the water out adapter nut.
Preferably, the endoporus of described water out adapter is provided with the U-loop groove, in the U-loop groove, is provided with O-ring seals.
Preferably, the end of described water out adapter is provided with the internal taper hole that is bell mouth shape, and awl cylindricality gland is installed in the taper hole.
Preferably, the described awl cylindricality gland that is installed in the taper hole is provided with the male cone (strobilus masculinus) that matches with water out adapter end internal taper hole.
Preferably, the described awl cylindricality gland that is installed in the taper hole adopts elastomeric material to make, and axially offers a breach at awl cylindricality gland.
When the utility model is installed, earlier O-ring seals is sleeved on the U-loop groove of water out adapter endoporus, and in its end is the internal taper hole of bell mouth shape, installs awl cylindricality gland additional, then water out adapter is screwed in the attaching nut, compress awl cylindricality gland; Because awl cylindricality gland adopts elastomeric material to make, under attaching nut's effect, joint is waled in contraction distortion tightly, thereby can guarantee effectively that water heater conduit's joint is water-tight.
The utility model has made radial seal into owing to traditional end surface is sealed, thereby has not only improved its sealing property effectively, and greatly reduces the requirement to the axial installation dimension of outlet pipe.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation, but be not restriction the utility model protection domain.
Like Fig. 2, shown in Figure 3, the described a kind of water heater conduit's joint of the utility model is made up of water out adapter 7, water out adapter nut 5, spacing ring 6, outlet pipe 10, joint 11,12 of attaching nuts.One end of outlet pipe 10 is connected with cartridge heater 1, and water inlet pipe 2 is installed on cartridge heater 1.Its joint 11 is sealing with outlet pipe 10 and is welded to connect, and attaching nut 12 is threaded with water out adapter 7; Spacing ring 6 is welded in the inboard of casing 3, and water out adapter 7 is fastened on the casing 3 through water out adapter nut 5.
The endoporus of described water out adapter 7 is provided with the U-loop groove, in the U-loop groove, is provided with O-ring seals 14.
The end of described water out adapter 7 is provided with the internal taper hole that is bell mouth shape, and awl cylindricality gland 13 is installed in the taper hole.
The described awl cylindricality gland 13 that is installed in the taper hole is provided with the male cone (strobilus masculinus) that matches with water out adapter 7 end internal taper holes.
The described awl cylindricality gland 13 that is installed in the taper hole adopts elastomeric materials to make, and axially offers a breach at awl cylindricality gland 13.
