Description
Technical field
The utility model relates to heat-generating pipe, the especially heat-generating pipe of a kind of heater, water heater etc. and the structure that spins of flange.
Background technology
The heating tube using on existing heater or water heater, is generally the welding method of welding in the overhead position by electric current and flange welding, during welding, can produce oxide layer, and the welding between heating tube and flange more or less, very inhomogeneous, cause drainage, affect the normal use of heating tube.
CN201680597U, the flange-type heating pipe that a kind of water heater is used is disclosed, its heating tube is riveted on flange, on flange inner surface, be provided with caulking gum, sealing and anticorrosion for described flange inner surface, although caulking gum has stoped water erosion in inner bag to arrive flange, and play sealing effectiveness with the acting in conjunction of riveted joint place, but several problems have been there are: 1, in order to realize sealing and the Corrosion Protection of rubber, must adopt all good extraordinary type rubber of high temperature resistant, resistance to water, ageing-resistant performance, its material cost has just improved greatly; 2, between heating tube and flange, rivet, between the two, only depend on the flange of riveted joint to connect, not only connect dynamics not high, when heating tube inserts in flanging bore, owing to being interference fit between flanging bore and heating tube outer wall, be easy to damage heating tube; 3, in inner bag, after water ebuillition of heated, can produce gas, act on heating tube, cause rocking of heating tube, the time slightly length will increase the gap between heating tube and rubber, flange, cause water in inner bag to leak in flange.
Utility model content
Purpose of design: avoid the weak point in background technology, design a kind of reduction material cost, strengthen connectivity robustness and improve sealing, avoid the heat-generating pipe that leaks and the structure that spins of flange.
Technical scheme: the structure that spins of a kind of heat-generating pipe and flange, the connection hole of its flange is extended with bulge loop to flange inside, the top that heat-generating pipe top is provided with rotary joint and heat-generating pipe passes the connecting hole of flange, after the connecting hole of heat-generating pipe and flange spins and spins, heat-generating pipe top forms to turn up and encases the bound edge of bulge loop, is provided with face closure formula weld part between heat-generating pipe and the connecting hole of flange.
Technical essential explanation: 1, top is provided with the heat-generating pipe of rotary joint and is provided with between the flange of bulge loop and spins, and is first technical characterictic of the present utility model.Heat-generating pipe top passes the connecting hole of flange, the rotary joint of heat-generating pipe is positioned at the outside of flange and the bottom that rotary joint is positioned at flange, and connecting hole is stretched out on heat-generating pipe top, the heat-generating pipe mouth of pipe is higher than the bulge loop of connection hole, utilize forcing press by after spinning between heat-generating pipe and flange, the heat-generating pipe mouth of pipe is encased bulge loop to turning up by distending, when not only having avoided traditional overhead welding, the structure that spins causes the drainage of heat-generating pipe due to the impact of oxide layer, guaranteed the complete of heat-generating pipe, and strengthened the stable connection between heat-generating pipe and flange, avoid rocking between heat-generating pipe and flange connecting hole, enhance product performance.2, screw-on place adopts the welding of face closure formula, is second technical characterictic of the present utility model.Contact-making surface between tradition heat-generating pipe and flange is not uniform, the Duo You position, position of causing the rear soldering paste of welding to have is few, the utility model is after spinning heat-generating pipe and flange, at bound edge place and rotary joint place, all beat soldering paste and soldering paste formation face closure weld part, due to the soldering paste of screw-on place be full infiltration be face infiltration, greatly increased the area at soldering paste sealing position, improved the sealing between heat-generating pipe and flange, and do not need to use rubber just can greatly improve the reliability of flange and heat-generating pipe sealing, effectively reduce material cost.
The utility model is compared with background technology, and the one, do not need to use rubber can greatly improve the sealing of heat-generating pipe and flange yet, effectively reduce material cost, also avoided in inner bag after the water after heating contacts with rubber, affecting the water quality in inner bag simultaneously; The 2nd, strengthen the steadiness being connected between heat-generating pipe and flange, guarantee the normal use of heat-generating pipe, improve the service life of product; The 3rd, the sealing area of expansion heat-generating pipe and flange, improves the sealing between heat-generating pipe and flange greatly, effectively avoids water in inner bag to leak in flange, improves the quality of products.
