The technical scheme that this utility model provides is: the water inlet pipe and water outlet pipe of a kind of water heater, including for putting in the body of water heater liner and for the electric heater pipe fitting being connected with water inlet mouthpiece or the water outlet mouthpiece pipe of water heater liner, one end of described electric heater pipe fitting has the female thread one coordinated with water inlet mouthpiece or water outlet mouthpiece pipe external screw thread；Body one end has external screw thread, has the female thread two coordinated with body external screw thread in electric heater pipe fitting, and female thread one mouth of pipe footpath is more than female thread two mouth of pipe external diameter, and female thread one mouth of pipe has a radial end face with the transition junction of female thread two mouth of pipe；Being arranged with conical seal ring or O-ring seals one on body, the large end face of conical seal ring contacts connection with described radial end face.
Also being arranged with sealing ring two on described body, the large end face of conical seal ring contacts connection by sealing ring two with described radial end face.
Described body is provided with O-ring seals groove one, and O-ring seals one is located in O-ring seals groove one.
Also being arranged with sealing ring three on described body, sealing ring three is positioned at female thread two mouth of pipe.
Described sealing ring three is O-ring seals two, and body is provided with O-ring seals groove two, and O-ring seals two is located in O-ring seals groove two.
Based on the design philosophy identical with such scheme, this utility model additionally provides following similar technical scheme: the water inlet pipe and water outlet pipe of a kind of water heater, including for putting in the body of water heater liner and for the electric heater pipe fitting being connected with water inlet mouthpiece or the water outlet mouthpiece pipe of water heater liner, described electric heater pipe fitting is made up of the big mouth of pipe and the little mouth of pipe, and the end of the big mouth of pipe has the female thread one consistent with water inlet mouthpiece or water outlet mouthpiece pipe external diameter；In body one stretches into electric heater pipe fitting and being welded to connect with the little mouth of pipe, the transition junction of the big mouth of pipe and the little mouth of pipe has a radial end face, and body is arranged with conical seal ring or O-ring seals, and radial end face contact described in the large end face of conical seal ring connects.
Also being arranged with sealing ring two on described body, the large end face of conical seal ring contacts connection by sealing ring two with described radial end face.
Described body is provided with O-ring seals groove one, and O-ring seals one is located in O-ring seals groove one.
This utility model is owing to using said structure, during use, this utility model water inlet pipe and water outlet pipe extends in inner container of electric water heater through water inlet mouthpiece or the water outlet mouthpiece pipe of inner container of electric water heater, sealed realizing between water inlet mouthpiece or the irregular inwall of water outlet mouthpiece pipe of the conical seal ring being set on body and inner container of electric water heater by the female thread one on electric heater pipe fitting and the water inlet mouthpiece of inner container of electric water heater or water outlet mouthpiece pipe external screw thread twisting force, not only good sealing effect, and easy for installation, more cost-effective.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of structure of the present utility model.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
See Fig. 1, this utility model includes the body 6 for putting in water heater liner and for the electric heater pipe fitting 1 being connected with water inlet mouthpiece or the water outlet mouthpiece pipe 5 of water heater liner, and one end of described electric heater pipe fitting 1 has the female thread 1 coordinated with water inlet mouthpiece or water outlet mouthpiece pipe 5 external screw thread；Body 6 one end has external screw thread, there is in electric heater pipe fitting 1 female thread 28 coordinated with body external screw thread, female thread 1 nozzle diameter is more than female thread 28 nozzle diameter, female thread one mouth of pipe has a radial end face 7 with the junction of female thread two mouth of pipe, being arranged with conical seal ring 3 on body, the large end face of conical seal ring 3 contacts connection with described radial end face 7.
Also being arranged with sealing ring 39 on described body 6, sealing ring 39 is positioned at female thread two mouth of pipe.
Also being arranged with sealing ring 22 on described body 6, the large end face of conical seal ring 3 contacts connection by sealing ring 22 with described radial end face 7.
Conical seal ring 3 of the present utility model is one end (small end) diameter less than the water inlet mouthpiece of water heater liner or water outlet mouthpiece pipe 5 inner diameter, the other end (end greatly) diameter more than the radial section of the water inlet mouthpiece of water heater liner or water outlet mouthpiece pipe 5 inner diameter is the tapered sealing ring of annular, axial cross section.According to this design philosophy, this utility model can use sealing ring such as O-ring seals, the y-shaped ring etc. of similar effect to replace described conical seal ring 3.When use O-ring seals time preferably add O-ring seals groove, the torsional deformation in case it is squeezed and affect sealing effectiveness.
Owing to water inlet mouthpiece or water outlet mouthpiece pipe 5 inwall of inner container of electric water heater are usually the coating materials such as enamel, limited by coating way or coating precision, the water inlet mouthpiece of inner bag or water outlet mouthpiece pipe 5 internal diameter present irregular change, this utility model uses conical seal ring 3, during installation, conical seal ring 3 is pressed in water inlet mouthpiece or water outlet mouthpiece pipe 5 pipe by the effect installing pressure and radial end face 7, and after conical seal ring 3 small end enters, it is squeezed equal to and more than the water inlet mouthpiece of water heater liner or conical seal ring 3 outer wall of water outlet mouthpiece pipe 5 inner diameter and makees radial deformation and be in close contact with water inlet mouthpiece or water outlet mouthpiece pipe 5 inwall, and then realize the excellent sealing between conical seal ring 3 and water inlet mouthpiece or water outlet mouthpiece pipe 5 inwall.
When this utility model uses, being inserted by body 6 in water inlet mouthpiece or the water outlet mouthpiece pipe 5 of inner container of electric water heater, conical seal ring 3 small end on body 6 enters with body 1；The female thread of electric heater pipe fitting 1 is connected with the water inlet mouthpiece of inner container of electric water heater or the external screw thread of water outlet mouthpiece pipe 5, then tightens.Conical seal ring 3 is pressed in water inlet mouthpiece or water outlet mouthpiece pipe 5 pipe by the effect installing pressure and radial end face 7, and after conical seal ring 3 small end enters, be squeezed equal to and more than conical seal ring 3 outer wall of water inlet mouthpiece or water outlet mouthpiece pipe 5 inner diameter and make radial deformation and be in close contact with water inlet mouthpiece or water outlet mouthpiece pipe 5 inwall.Sealing ring 22 sheathed on described body 6, between conical seal ring 3 and radial end face 7, makes better seal between water heater liner and electric heater pipe fitting 1.
