Abstract
Disclosed is a joint of an insulation pipe of the water heater, in particular to a joint which is arranged on an inlet or outlet pipes and the port of the joint of the inlet or the outlet pipes for connecting the inlet or the outlet pipes and the port of the joint of the inlet or the outlet pipes, and for separating the inlet or the outlet pipes from the port of the joint of the inlet or the outlet pipes to strengthen the insulation effect. The inlet or the outlet pipes and the joint of the inlet or the outlet pipes are arranged on the solar water heater, the electric water heater, the gas water heater or the fast electric water heater. The utility model is composed of a pipe with thread, and the middle of the pipe is provided with through holes; the through holes are step-shaped; and the pipe with the thread is provided with a concave ring groove with thread which is parallel to the through holes, and sealing rings are arranged inside the concave ring groove. With simple and compact structure, the single joint of the insulation pipe can connect the inlet or the outlet pipes and the joint of the inlet or the outlet pipes as a whole. The original water heater is not provided with the joint, but after the joint is additionally arranged on the water heater, the insulation strength of the inlet and the outlet pipes is strengthened. Therefore, the water heater can be prevented from leaking electricity and the hidden danger brought by other household appliances can be avoided. Thus, the water heater can be safer and more reliable.
Description
Technical field
The utility model relates to the part on a kind of water heater, pipe joint, on particularly a kind of mouth that is installed in inlet tube and outlet tube on solar water heater, electric heater, gas heater, the quick electric water heater etc. and water-in and water-out pipe joint, connect and be integral, and it is separated, be used for reinforced insulation, guarantee the insulation tube joint of the water heater that the user is safe in utilization.
Background technology
Raising along with people's living standard, various household electrical appliance colour TVs, refrigerator, refrigerator-freezer, washing machine, water heater etc. all enter each family one after another, constantly popularize, contact, the people who uses are also more and more, and these household electrical appliance are if install, improper use will threat to life safety.Household electrical appliances manufacturer all can consider security of products on the design source for this reason, takes measures, and avoids as far as possible because the danger that user misoperation is brought.Allow the user use relieved, safety.On the existing commercially available all kinds and the water heater of shape, go back the naked pipe joint.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of insulation tube joint of water heater is provided, installs and uses on all inlet tube and outlet tubes on the water heater and inlet tube and outlet tube connection port, improve the dielectric strength of the mouth of pipe, it is safer, reliable that water heater is used.
The utility model solve the problems of the technologies described above the technical scheme that adopted by: the insulation tube joint of water heater has through hole, threaded pipe to be constituted by the centre, described through hole is a stepped bore, also comprises on the described threaded pipe being threaded, being placed with the sealing ring concave ring groove parallel with through hole.
Compared with prior art, advantage of the present utility model is that this insulation tube joint design is simple, compact, and a part will advance or outlet pipe and advance or titting water outlet connects into integral body simultaneously, and volume is little.Do not have this joint on the former water heater, now increased this joint, just increased the dielectric strength of inlet tube and outlet tube, can prevent that the water heater electric leakage from reaching the dangerous steady trouble that household electrical appliance brought by other, uses safer, reliable.
Description of drawings

Fig. 2. structural representation of the present utility model (cooperating) with pipe joint, inlet tube and outlet tube.
Fig. 3. the utility model alternative plan structural representation (cooperating) with pipe joint, inlet tube and outlet tube.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Insulation tube joint 1 ', the lower end is tubular for the band gas thread, and there is stairstepping through hole 2 centre, the upper end have on the through-hole wall with the concave ring groove 3 of through hole 2 equalitys ', have on concave ring groove 3 ' one side through hole 2 stepped wall external screw thread 4 ', concave ring groove 3 ' in be placed with conventional O RunddichtringO 5 ', as shown in Figure 3.
During use, with this insulation tube joint 1 or 1 ' be connected with inlet tube and outlet tube 6,8 with water-in and water-out pipe joint 7,9 on the water heater, as shown in the figure.Through hole 2 cooperates with inlet tube and outlet tube 6,8 respectively, and with the internal thread on it 4, and external screw thread 4 ' with the water-in and water-out pipe joint 7,9 on the water heater is fixedlyed connected and is integral, and just can use, as growing shown in the water pipe 6 in the middle of Fig. 1.Also can with inlet tube and outlet tube 6 ', 8 and insulation tube joint 1 or 1 ' directly be injection molded into and be made into integration by insulating materials, and then be threaded with water-in and water-out pipe joint 7 or 9 and be integral, as both sides short tube 6 among Fig. 1 ' shown in.Because of having increased this insulation tube joint at the original water-in and water-out mouth of pipe and inlet tube and outlet tube connection port place, just can increase its insulaion resistance, use safer, reliable.
