Abstract
The invention discloses a water pipe connector of a water heater. The water pipe connector of the water heater comprises a water outlet connector, a water outlet connector nut, a limiting ring, a water outlet pipe, a connector and a connecting nut, and is characterized in that the connector is hermetically connected with the water outlet pipe in a welding manner; the connecting nut is in threaded connection with the water outlet connector; the limiting ring is welded on the inner side of a tank body, and the water outlet connector is fastened on the tank body through the water outlet connector nut. According to the water pipe connector of the water heater, the traditional end surface sealing is changed into radial sealing, and two seals of an O-shaped seal ring and a conical-cylindrical pressing sleeve are arranged, so that not only is the sealing property effectively improved, but also the requirement on the axial installation dimension of the water outlet pipe is greatly reduced.
Description
Technical field
The present invention relates to a kind of electromagnetic water heater water pipe adapter new structure, belong to electromagnetic water heater manufacturing technology field.
Background technique
The water route part of electromagnetic water heater mainly is comprised of institutes such as heating cylinder, jointing, water pipes.Water pipe is the link of each several part, is generally the tubule class, and needs the space to arrange, the characteristics such as that this class water pipe has is lightweight, poor rigidity, intensity are low, therefore, water pipe must guarantee its reasonable stress in connection procedure, must not bear larger extra load, water pipe stretches, distortion otherwise easily make, and cracks and make adjacent joint poor sealing, causes water leakage phenomenon, such as the water power contact, more bather's personal safety is produced hidden danger.Fig. 1 is the structural representation of the electromagnetic water heater water route part of common usefulness.It mainly is comprised of heating cylinder 1, intake pipe 2, casing 3, Female connector fittings 4, water output connector nut 5, limited ring 6, water output connector 7, sealing gasket 8, joint 9, outlet pipe 10.Outlet pipe 10 is welded together with joint 9, and weld seam is water-tight; Limited ring 6 is welded on the box inside face, and water output connector 7 passes through the hexagonal shaft hole matching with limited ring 6, tightens water output connector nut 5, and the step end face of water output connector 7 is close on the inner side surface of casing 3.Though this heating cylinder titting water outlet structural design is simple, requires the axial dimension of water pipe very accurate, although 4 mounting plates of heating cylinder 1 all are provided with slotted hole, can only adapt to the position of water inlet and outlet one end water pipe.Behind the position of satisfying intake pipe 2, outlet pipe 10 end faces can not be fitted with water output connector 7 end faces after loading onto sealing gasket 8 sometimes well.After forcing fastening nut 4, can make water pipe 10 be subject to extra additional force.Affect the working life of water pipe 10.If not fastening nut 4 easily makes again sealing gasket 8 places produce water leakage phenomenon.
Summary of the invention
In view of the problem of above-mentioned existence, the purpose of this invention is to provide the water pipe joint of water heater of a kind of rational in infrastructure, simple installation, reliable performance, use safety.
For achieving the above object, the present invention has taked following technological scheme:
A kind of water pipe joint of water heater of the present invention is made of water output connector, water output connector nut, limited ring, outlet pipe, joint, attaching nut, it is characterized in that joint and outlet pipe are seal welding and are connected; Attaching nut and water output connector are threaded; Limited ring is welded in the inboard of casing, and water output connector passes through the water output connector fastening nuts on casing.
Preferably, the endoporus of described water output connector is provided with the U-loop groove, in the U-loop groove, is provided with O-ring seals.
Preferably, the end of described water output connector is provided with the internal taper hole that is bell mouth shape, and cone cylindricality gland is installed in the taper hole.
Preferably, the described cone cylindricality gland that is installed in the taper hole is provided with the male cone (strobilus masculinus) that matches with water output connector end internal taper hole.
Preferably, the described cone cylindricality gland that is installed in the taper hole adopts elastic material to make, and axially offers a breach at cone cylindricality gland.
When the present invention installs, first O-ring seals is sleeved on the U-loop groove of water output connector endoporus, and within its end is the internal taper hole of bell mouth shape, installs cone cylindricality gland additional, then water output connector is screwed in the attaching nut, compress cone cylindricality gland; Because cone cylindricality gland adopts elastic material to make, under attaching nut's effect, joint is waled in contraction deformation tightly, thereby can guarantee effectively that water pipe joint of water heater is water-tight.
The present invention has been owing to having made traditional end face seal into radial seal, thereby not only effectively improved its sealability, and greatly reduces the requirement to the axial installation dimension of outlet pipe.

Embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing, but be not limiting the scope of the invention.
Such as Fig. 2, shown in Figure 3, a kind of water pipe joint of water heater of the present invention is made of water output connector 7, water output connector nut 5, limited ring 6, outlet pipe 10, joint 11, attaching nut 12.One end of outlet pipe 10 is connected with heating cylinder 1, at heating cylinder 1 intake pipe 2 is installed.Its joint 11 is seal welding with outlet pipe 10 and is connected, and attaching nut 12 is threaded with water output connector 7; Limited ring 6 is welded in the inboard of casing 3, and water output connector 7 is fastened on the casing 3 by water output connector nut 5.
The endoporus of described water output connector 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 output connector 7 is provided with the internal taper hole that is bell mouth shape, and cone cylindricality gland 13 is installed in the taper hole.
The described cone cylindricality gland 13 that is installed in the taper hole is provided with the male cone (strobilus masculinus) that matches with water output connector 7 end internal taper holes.
The described cone cylindricality gland 13 that is installed in the taper hole adopts elastic materials to make, and axially offers a breach at cone cylindricality gland 13.
When the present invention installs, first O-ring seals 14 is sleeved on the U-loop groove of water output connector 7 endoporus, again water output connector 7 is fixed on the casing 3, heating cylinder 1 installs on the casing 3 together with the outlet pipe 10 that installs, joint 11, simultaneously within its end is the internal taper hole of bell mouth shape, install cone cylindricality gland 13 additional, and joint 11 is inserted in the hole of water output connectors 7 fastening heating cylinder 1, then water output connector 7 is screwed in the attaching nut 12, compresses cone cylindricality gland 13; Because cone cylindricality gland 13 adopts elastic material to make, and offers an axial gap, under attaching nut 12 effect, joint 11 is waled in contraction deformation tightly.Outlet pipe 10, joint 11, water output connector 7 just link together tightly like this.
The present invention has been owing to having made traditional end face seal into radial seal, and is provided with O-ring seals 14 and cone cylindricality gland 13 two seals, thereby not only effectively improved its sealability, and greatly reduces the requirement to the axial installation dimension of outlet pipe.
