Abstract
The utility model relates to a split type electric isolating wall for an electric water heater, comprising a connector, an insulating water pipe, a metal pipe joint with an external thread, an internal threaded interface and a sealing ring, wherein the connector is formed through injection molding; the internal threaded interface is made of metal; a water through passage is arranged on the connector; the lower part of the insulating water pipe is provided with a circular ring baffle; a sunken hole is arranged at one end of the connector connected with the insulating water pipe; the internal threaded interface made of metal is fixedly connected with the sunken hole; the sealing ring is jointed with a bottom plate of the sunken hole; the upper end surface of the sealing ring is jointed with the circular ring baffle; an interface at the other end of the connector is inserted into the metal pipe joint and is fixedly connected with the metal pipe joint; and the internal threaded interface made of metal and the metal pipe joint are pre-embedded on the connector. The above structure is adopted and the metal pipe joint and the internal threaded interface made of metal are pre-embedded on the connector, so that the technique is simple; the insulating water pipe is detachably connected with the connector, so that the sealing ring is convenient to assemble, maintain and replace; the maintenance is convenient, the cost is saved and integral scrapping due to maintenance failure is prevented.
Description
Technical field
The present invention relates to the device that a kind of electric heater is used.
Background technology
Present prior art; since the enforcement of 2006 editions storage-type electric water heater new national standards; domestic electric heater producer is one after another in " Fang Dianqiang " technology that prevents to have released aspect the charged earth leakage protective of electrothermal tube electric leakage and water pipe oneself, is that 200720141261.0 this " Fang Dianqiang " utilize the principle of water resistance to reduce the method for delivery port place electric current as the disclosed patent No.; though above-mentioned patent has played the certain protection effect; but complex structure; be difficult to processing; be difficult for installing; the cost height; the versatility of part is not strong; the dismounting difficulty; the cost of after-sales service and replacing parts is also higher.
Summary of the invention
The objective of the invention is: the split type electricity-isolation wall that provides a kind of electric heater to use, it is not only easy to process, and cost is low, and highly versatile, dismounting, easy to maintenance.
The present invention is achieved in that the split type electricity-isolation wall that a kind of electric heater is used, and its special character is: the internal thread interface and the sealing ring that comprise the connector that the injection moulding mode makes, the water pipe that insulate, make with externally threaded metallic pipe coupling, metal material; One waterway is arranged on the connector;
One annulus baffle plate is arranged at the bottom of described insulation water pipe; Connector has a counterbore with the end that the insulation water pipe is connected; The internal thread interface that metal material is made is fixedlyed connected with counterbore;
The base plate of described sealing ring and counterbore is fitted; The upper surface of sealing ring and annulus baffle plate are fitted;
The interface of the connector other end inserts in the metallic pipe coupling and is fixed together;
The internal thread interface that described metal material is made is embedded in the connector, and metallic pipe coupling is embedded on the connector.
The split type electricity-isolation wall that described a kind of electric heater is used, its special character is: on the connector of counterbore bottom the cannelure that is communicated with counterbore is arranged, an annular edge is arranged at the internal thread interface bottom, and annular is along chimeric with cannelure;
Described metallic pipe coupling is connected an end with connector have the outer folding of annular along plate, and annular slot is arranged on the connector, and the outer folding of annular cooperates with annular slot along plate.
The split type electricity-isolation wall that described a kind of electric heater is used, its special character is: the bottom of described counterbore annular protrusion arranged, annular protrusion is around the waterway of connector;
Annular protrusion inserts in the sealing ring.
The split type electricity-isolation wall that a kind of electric heater of the present invention is used, owing to adopt such structure, the internal thread interface that metallic pipe coupling and metal material are made is embedded on the connector, technology is simple; Insulation water pipe and connector removably connect, and assembling, maintenance, replacing sealing ring are conveniently; Convenient for maintaining has been saved cost, prevents to keep in repair, and integral body is scrapped.
Description of drawings
Fig. 1 is a cutaway view of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
As shown in Figure 1, the split type electricity-isolation wall that a kind of electric heater is used, the internal thread interface 5 and the sealing ring 4 that comprise connector 1 that the injection moulding mode makes, insulation water pipe 2, make with externally threaded metallic pipe coupling 3, metal material; One waterway is arranged on the connector 1;
