Abstract
The utility model relates to a water inlet and outlet aqueduct of a water heater. The water inlet and outlet aqueduct of a water heater comprises an aqueduct body which is provided with a subuliform seal ring. A check ring device for preventing the subuliform seal ring from an axial motion is arranged on the outer wall of the aqueduct body at the two ends of the subuliform seal ring. Or the water inlet and outlet aqueduct of a water heater comprises an aqueduct body; an outer wall of the aqueduct body connected with a connector is subuliform. A seal ring is arranged on the outer wall of the subuliform aqueduct body. A check ring device for preventing the seal ring from an axial motion is arranged on the outer wall of the aqueduct body at the two ends of the seal ring. While using, the water inlet and outlet aqueduct pass through the water inlet and outlet and extend to a liner of an electric water heater, the sealing between the subuliform seal ring sleeved on the aqueduct body and the irregular inner wall of the water inlet and outlet of the electric water heater is achieved under the torsion effects of a screw thread on the threaded pipe body and the screw thread outside the water inlet and outlet of the electric water heater. The sealing effects are good. The water inlet and outlet aqueduct of water heater are convenient to assemble, and the cost is also saved.
Description
Technical field
The utility model relates to the electric heater accessory, specifically the Inlet and outlet water aqueduct of water heater.
Background technology
Electric heater is widely used in people's life.But because electric heater directly contacts with water, in case electric leakage will make water charged, bring the danger of electric shock to the user.Thereby, be incorporated into inlet tube and outlet tube
OnAnti-electric wall technology be widely used.The principle of anti-electric wall technology is to utilize water body itself to have the characteristic of resistance, and possible leakage current is decayed within the safe scope.Normally used anti-electric wall is the insulation water pipe to be passed the electric heater intake-outlet extend in the inner container of electric water heater, and anti-electric wall was lost efficacy, the electric heater entery and delivery port must and extension tube attached between realize being tightly connected.Be to be threaded with the electric heater entery and delivery port and must to adopt as twine the seal approach of the classes such as unsintered tape by silk mouth pipe such as existing one of the mode that is tightly connected, the insulation water pipe is located in the silk mouthful pipe and passes the electric heater entery and delivery port and extends in the inner container of electric water heater.This class mode that is tightly connected is not only installed complexity, and sealing effectiveness is undesirable.
Summary of the invention
Problem to be solved in the utility model provides a kind of water-in and water-out aqueduct of water heater, the water-in and water-out aqueduct of this water heater can realize well and the electric heater entery and delivery port between be tightly connected, good sealing effect not only, and easy for installation, and save cost.
The technical scheme that the utility model provides is: a kind of water-in and water-out aqueduct of water heater, comprise body, and be arranged with conical seal ring on the body, the tube wall at conical seal ring two ends is provided with the back-up ring device that prevents the conical seal ring axially-movable.
The another kind of technical scheme that solves the utility model problem is: a kind of water-in and water-out aqueduct of water heater, comprise body, it is characterized in that: tapered with the tube wall of water heater interface connecting portion, be arranged with sealing ring on the tapered tube wall, the tube wall at sealing ring two ends is provided with the back-up ring device that prevents the sealing ring axially-movable.
Described sealing ring is isometrical sealing ring or conical seal ring.
Back-up ring device described in the utility model is the back-up ring ring that is one with body.
Back-up ring device described in the utility model also can be several back-up ring stake and back-up rings that are fixed on the tube wall.
The utility model is owing to adopt said structure, during use, the water-in and water-out aqueduct of water heater passes the electric heater entery and delivery port and extends in the inner container of electric water heater, to be set in by the screw thread on the screw-thread pipe body and electric heater water-in and water-out interface external thread twisting force and to realize sealing between conical seal ring on the body and the irregular inwall of electric heater entery and delivery port, good sealing effect not only, and easy for installation, more save cost.
Description of drawings
Fig. 1 is the schematic diagram of structure of the present utility model.
Fig. 2 is the connection diagram of the utility model and electric heater water-in and water-out interface.
Fig. 3 is the schematic diagram of the another kind of 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. 1-2, the utility model comprises body 1, is arranged with conical seal ring 2 and O RunddichtringO 3.1,3.2 on the body 1, and body 1 outer wall at conical seal ring 2 two ends is provided with the positioning retainer ring device 4,5 that prevents conical seal ring 2 axially-movables.Described positioning retainer ring device 4,5 to be stopping conical seal ring 2 along body 1 axially-movable as basic demand, as adopting the back-up ring ring that is fixedly connected with body 1 or being fixed on several back-up ring stakes on the tube wall.Back-up ring ring, back-up ring stake can be one with body processing.Because electric heater advances, water outlet mouthpiece 6 inwalls are generally the coating materials such as enamel, be subjected to the restriction of coating way or coating precision, electric heater advances, water outlet mouthpiece 6 internal diameters present irregular variation, the utility model adopts conical seal ring 2, during installation, conical seal ring 2 is subjected to setting pressure and back-up ring device 4,5 effect, can only make radial deformation and advance with electric heater, water outlet mouthpiece 6 inwall close contacts, and then realize that conical seal ring 2 and electric heater advance, excellent sealing between water outlet mouthpiece 6 inwalls, conical seal ring also has the installation guide effect simultaneously, and back-up ring device 4 also has positioning action.
When the utility model uses (referring to Fig. 2), body 1 is inserted in the electric heater water-in and water-out interface 6, conical seal ring 2 small ends on the body 1 enter with body 1; Electric heater screw socket pipe fitting 7 is enclosed within on the utility model body 1, and the internal thread of electric heater screw socket pipe fitting 7 and the external screw thread of electric heater water-in and water-out interface 6 are connected, then tighten.Conical seal ring 2 is subjected to setting pressure and back-up ring device 4 in the rundown process, 5 effect, entering in the water heater water-in and water-out interface 6 with body 1 when, can only make radial deformation and with electric heater water-in and water-out interface 6 inwall close contacts.Be set in simultaneously O RunddichtringO 3.1 on the body 1 one end toper bodys, 3.2 and electric heater screw socket pipe fitting 7 conical inboard walls stressed close contact and realize excellent sealing between body 1 of the present utility model and water heater screw socket pipe fitting 7 and the electric heater water-in and water-out interface 6 simultaneously.
The utility model also can adopt version as shown in Figure 3 to realize.Be about to aqueduct body 1 outer wall (with body 1 outer wall of electric heater interface connecting portion) corresponding with electric heater water-in and water-out interface and be made as taper, and the sealing ring 2 that is installed on this section outer wall is isometrical sealing ring or conical seal ring, sheathed O RunddichtringO 3.1,3.2, body 1 outer wall are provided with the back-up ring device 4,5 that prevents sealing ring 2 axially-movables on the body 1, sealing ring 2 shapes of its outside become taper under aqueduct outer wall taper effect, form good sealing under the effect that external force is installed and between the irregular internal diameter of water heater Inlet and outlet water interface inwall.
