Abstract
The utility model relates to a screwed pipe for a water inlet/outlet pipe of a water heater, which comprises a nonmetal pipe body, wherein the two ends of the nonmetal pipe body are provided with threads; and the threads at the two ends of the nonmetal pipe body are all external threads. Since the structure is adopted by the screwed pipe, the materials, the manpower and the electric energy are saved, the efficiency is improved, and whether the sealing performance is good or not after the screwed pipe is mounted is easy to observe.
Description
Technical field
The utility model relates to the Inlet and outlet water mouth of pipe device of water heater, specifically the silk of heater inleting pipe or outlet pipe mouthful pipe.
Background technology
The hot water or cold water's of water heater silk mouthful pipe, the screw thread of silk mouth adopts internal thread mostly.Internal thread is consume material not only, and the machined difficulty is big, and is time-consuming, take electricity, expense manpower, when infiltration in the interface time is difficult to find.
Summary of the invention
The purpose of this utility model provides a kind of and has saved material, has saved manpower, saved electric energy at the weak point of the water-in and water-out pipe joint of existing water heater, and is easier to observe the silk mouthful pipe that the water heater of better seal inlet tube and outlet tube is arranged.
The technical scheme that the utility model provides is: a kind of silk of water heater inlet tube and outlet tube mouthful pipe, comprise nonmetal body, and nonmetal body two ends are provided with screw thread, and the screw thread at nonmetal body two ends is external screw thread.
The screw thread at above-mentioned nonmetal body two ends is metal threaded or nonmetal screw thread, or nonmetal body one end is that the metal threaded other end is nonmetal screw thread, or nonmetal body one end is that the metal threaded other end is metal and nonmetal combination screw thread.
Be embedded with electric conductor in the described nonmetal body, electric conductor one end and metal threaded electrically connecting, the electric conductor other end is exposed on the silk mouthful pipe outer wall.
Described electric conductor is to make electric conductor and metal threaded tight the electrically connecting of forming that contact by pressuring method with metal threaded electrically connecting.
When the screw thread at nonmetal body two ends is nonmetal screw thread, nonmetal screw thread bottom is provided with the quoit that is fixed on the nonmetal body, be embedded with electric conductor in the nonmetal body, electric conductor one end closely contacts to form with quoit and electrically connects, and the electric conductor other end is exposed on the silk mouthful pipe outer wall.
Be inserted with aqueduct in the silk mouthful pipe of the present utility model.
The utility model is not only saved material, saves manually, saves electric energy, is raised the efficiency owing to adopt said structure, and is easier to observe after it is installed whether better seal is arranged.
Description of drawings
Fig. 1 is the schematic diagram of a kind of version of the utility model;
Fig. 2 is the schematic diagram of the another kind of version of the utility model;
Fig. 3 is the schematic diagram of the third version of the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1-Fig. 3, the utility model comprises nonmetal body 1, and the screw thread at nonmetal body two ends is external screw thread.
The screw thread at described nonmetal body two ends is nonmetal screw thread 2(referring to Fig. 1) or metal threaded 6; Or nonmetal body one end is that metal threaded 6 other ends are that nonmetal screw thread is (referring to Fig. 2, the end that is connected with water heater of suggestion adopts metal threaded), or nonmetal body one end is that metal threaded 6 other ends are the combination screw thread (promptly making up a part of in the complete section screw thread of screw thread is that a metal threaded part is nonmetal screw thread) of metal 6 and nonmetal 2.
Be inserted with aqueduct 3 in the silk mouthful pipe.
During making, for adopting metal threaded or during the combination screw thread, earlier will metal threaded 6 or the combination screw thread prefabricated, place it in again in the mould of silk mouthful pipe, inject nonmetallic materials, take out after the moulding, promptly get required silk mouth and manage.
Be embedded with electric conductor 4 in the described nonmetal body 1, electric conductor 4 one ends and metal threaded 2 or quoit 5 electrically connect, the other end be exposed to the silk mouthful the pipe outer wall on.The electric conductor end that is exposed on the silk mouthful pipe outer wall is connected with external function spare, can detect water heater and whether leak electricity, also can be used as the signal that cuts off water heater power supply, guarantee that the user is safe in utilization.
Described electric conductor 4 with metal threaded 6 or quoit 5 modes of electrically connecting can adopt welding, but pressurization makes electric conductor 4 and metal threaded 6 closely contact electrically connect (need not weld auxiliary material like this, can guarantee its permanent effectively conducting effect to pad) of formation during preferably by moulding.
The utility model also has the following advantages:
1, because the utility model technology has adopted non-metallic pipe and metal threaded or nonmetal screw thread or nonmetal and metallic combination screw thread one one-shot forming, saved processing cost greatly.
2, present technique has adopted two external thread structures, makes the volume of finished product littler, has saved material greatly, has saved artificial, power saving, has improved production efficiency.
