Summary of the invention
The water heater of exempting from the flexible pipe connection that the utility model provides a kind of low cost of manufacture simple in structure, easy to connect, relative to be suitable for promoting.
A kind of water heater of exempting from the flexible pipe connection; Comprise water heater; The delivery port of water heater and water inlet are provided with threaded tube connector, and said threaded tube connector connects loose joint, and valve body one end of valve is located in loose joint; The other end integrated injection molding tubulose extension of the relative loose joint of valve body, the valve body of valve is a plastic material.The valve body structure that this kind adopts plastic material to process is provided with the loose joint structure at valve one end; The other end is provided with the tubulose extension with the valve body one; Through valve two ends material different and syndeton; Realization is by the threaded tube connector of loose joint connection water heater, and the direct hot melt in tubulose extension connects the plastic tube of family's water-heating system, avoids the use of the complicated and high technological deficiency of manufacturing integrated cost of installation that flexible pipe causes fully.Loose joint is a kind of of pipe fitting, and profile is three-dimensional polygon design, and internal layer is carved with three-dimensional screw thread, and type of attachment is an anchor tip and the supporting use of a movable nut joint, and two ends and respective tube screw thread join, and be middle with PVC pad or rubber seal.The plastic material of valve body of the present invention can all can for thermoplastics such as PE, PP, PVC, PP-R.
Valve body plastic raw materials as the described valve of structure optimization is the PP-R material, because the raw molecule of PP-R has only carbon, protium, does not have harmful poisonous element to exist; Health is reliable; Not only be used for the hot and cold water pipeline, also can be used for the purified water for drinking system, nontoxic, health.
The valve body of described valve and tubulose extension are that the injection moulding of same plastic one constitutes.Described tubulose extension hot melt is connected with plastic tube, and the material of tubulose extension is identical with plastic tube, improves the seal of plastic tube and the extension welding of valve body tubulose, and certain above-mentioned plastic tube can connect whole plumbing pipe system.
Described loose joint is made up of metal tube and the nut that is placed in the metal tube periphery; Metal tube one end is provided with the positive stop end of restriction nut axial stroke, and the other end connects the valve body of valve.As the preferred connected mode of metal tube and valve body, metal tube is provided with the through hole of vertical tube wall on the tube wall of valve body link, and through hole is filled by the injection moulding of valve body one, and valve body is the outer tube wall of thermoplastic clad metal pipe link simultaneously.Thermoplastic is meant the valve body of plastic material in the injection machine injection moulding, and the valve body material of thawing directly coats other materials such as metal tube, valve rod in mould, is fastenedly connected the process of other materials such as metal tube after the cooling.The connected mode of this kind original creation is utilized the through-hole structure on the metal tube tube wall to incorporate the valve body material and is coated the connection metal tube by the direct thermoplastic of valve body material, makes that the material of two kinds of unlike materials of metal tube and valve body is connected closely.
Described valve comprises valve body and spool, the valve rod be located in the valve body, and spool and valve rod periphery all are connected with sealing ring; Described valve body is in making injection moulding process, and the valve body thermoplastic coats the sealing ring that connects spool and spool periphery, and valve body thermoplastic simultaneously coats the sealing ring that connects valve rod and valve rod periphery, and this kind syndeton has improved the valve overall tightness greatly.
Described valve rod is provided with radially the annulus of protrusion near spool one end, and the annulus periphery is with sealing ring, the leak of liquid of the valve that prevents to flow through.
The utility model is through the valve of band loose joint; Realization is connected the threaded tube connector of water heater by loose joint; And the direct hot melt in valve tubulose extension connects the plastic tube of family's water-heating system, avoids the use of the complicated and high technological deficiency of manufacturing integrated cost of installation that flexible pipe causes fully.
