Description
Technical Field
The invention belongs to the field of heating pipes of water dispensers, and particularly relates to a flange packaging structure for mounting an electric heating pipe.
Background
In the prior art, the flange plate of the electric heating pipe is installed by penetrating the electric heating pipe on the horizontal flange plate surface, the electric heating pipe leads the rod to stretch out to the lower terminal surface from an upper end surface of the flange plate, the electric heating pipe penetrates through a gap between the electric heating pipe and the flange plate from the upper end surface, then the connecting sheet is used for connecting two electric heating pipe leading rods, then the connecting sheet and two leading rods are fixed by using two nuts (or the connecting sheet is not used, and each leading rod is fixed by using the nut alone), and the nuts are easy to rust and loosen after a long service life to influence the connection firmness. Gaps at the contact positions of the electric heating tubes and the flange plates are easy to rust; the sealing washer relies on frictional force itself to locate the heating pipe periphery not fixed, and the sealing washer stretches into in heating the water cavity, accumulates impurity such as incrustation easily, and also easily receives the rust influence with the heating pipe is nearer apart from, and then the health of the drinking water of this electrothermal tube heating is used in the influence, and the ring flange is close to the edge and opens there is the ring flange mounting hole, and the leakproofness of health and installation is influenced in the also easy infiltration of mounting hole department, influences the life of electrothermal tube and ring flange, also does not benefit to the health and sanitation of people's drinking water.
Disclosure of Invention
The invention aims to solve the problems of health and sanitation and easy flange contact Shui Yi rusting and corrosion of the flange in the flange mounting and heating of the electric heating tube for heating drinking water at present, and provides a flange packaging structure for mounting the electric heating tube.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a flange packaging structure of installation electrothermal tube, includes the electrothermal tube, flange packaging structure still includes ring flange and sealing washer, the ring flange middle part is equipped with the bellying, the electrothermal tube is located on the bellying, the sealing washer is located bellying periphery, it has first through-hole to open on the sealing washer, be equipped with on the ring flange with the second through-hole that first through-hole position corresponds. The convex surface provided with the electric heating tube extends into the heating cavity of the drinking water, and the first through hole is arranged between the sealing ring and the flange plate. The second through hole can be fixed through fasteners such as screws, the firmness of installation between the sealing ring and the flange plate is improved, and the sealing performance in use is relatively improved.
Furthermore, the end of the electric heating tube is connected with the convex surface in a sealing way. The sealing connection in this scheme can adopt argon arc welding, never reveals, can avoid electrothermal tube and protruding face contact water to arouse to rust and the drinking water pollution that brings.
Further, the height of the sealing ring is larger than that of the convex surface. In order to improve the tightness of the connection between the flange structure and the flange on the further component.
Further, an upward flange is arranged on the edge of the upper end face of the flange plate, and the sealing ring is located between the flange and the protruding face.
Furthermore, a gap is reserved between the inner ring of the sealing ring and the convex surface, and the outer ring of the sealing ring is tightly attached to the flange.
Furthermore, the distance between the flange pipe and the edge of the convex surface is larger than the pipe diameter of the flange pipe. The distance between the sealing ring and the electric heating tube is enlarged, the temperature of water which is closer to the periphery of the electric heating tube is higher in the heating process of the electric heating tube, the influence of the high-temperature water on the heat generated by the sealing ring is avoided, the service life of the sealing ring is prolonged, and the firmness of flange installation is improved.
In a further arrangement, the outer edge of the convex surface is in arc transition. The abrasion of the sealing ring caused by friction can be avoided during installation.
Further setting, the arbitrary adjacent two of ring flange lower extreme face draw stick and a stationary blade rigid coupling, can adopt modes such as welding, and it is more firm than traditional nut fixed connection, difficult not hard up.
Furthermore, the fixing piece is composed of a main board and an auxiliary board, the surface of the main board is fixedly connected with any two adjacent end parts, and a third through hole is formed in the auxiliary board. The third through hole can be uniformly connected with all the electric heating tubes, so that a power supply can be conveniently connected.
Furthermore, the main plate and the auxiliary plate are metal sheets which are folded into 90 degrees.
Still further, the main board is hinged with the auxiliary board. So that the connection and management installation flexibility between the guide rods is higher.
Compared with the prior art, the invention has the beneficial effects that: compared with the traditional electric heating tube flange structure, the flange structure has better firmness and better sealing performance, is not easy to rust, and is more beneficial to the safety and sanitation of drinking water of a human body.
Drawings
FIG. 1 is a schematic diagram of an embodiment of the present invention;
fig. 2 is a schematic bottom view of another configuration of the present invention.
In the figure: the electric heating tube comprises an electric heating tube 1, a flange 2, a convex surface 3, a sealing ring 4, an inner ring of a sealing ring 41, an outer ring of a sealing ring 42, a flange 5, a first through hole 6, a second through hole 7, a fixing piece 8, a main board 9, an auxiliary board 10, a third through hole 11, an electric heating tube leading rod 12, an electric heating tube end 13 and a convex surface outer edge 31.
Detailed Description
The technical solution of the present invention is further described below by means of specific examples.
As shown in figure 1, a flange packaging structure for mounting an electric heating tube, wherein a convex surface 3 is arranged on the upper end surface of a flange 2, the electric heating tube 1 is mounted on the convex surface, a sealing ring 4 (namely a sealing gasket) is sleeved on the periphery of the convex surface, a first through hole 6 can be formed in the sealing ring, a second through hole 7 corresponding to the first through hole is formed in the flange, and the first through hole and the second through hole can be fixedly connected with a flange on a heating device (such as a water heating cavity) using the flange packaging structure through a fastening piece, so that the sealing property is improved, and the water seepage caused in the traditional mounting process is avoided.
The connection part of the electric heating tube end part 13 and the convex surface 3 is hermetically connected. For improving the leakproofness more according to the user demand, the sealing washer height can set up to be greater than the bellying height for and avoid the rivers in the cavity to spill from between the flange after the installation between the flange that corresponds the heating chamber. And an upward flange 5 is arranged at the outer edge of the upper end face of the flange plate, and the sealing ring 4 is positioned between the flange and the convex face. As one arrangement, a gap is left between the inner ring 41 of the seal ring and the convex surface, and the outer ring 42 of the seal ring is closely attached to the flange. The distance L between the flange pipe and the edge of the convex surface is larger than the pipe diameter D of the flange pipe.
