Technical field
The utility model relates to a kind of flange form electric heating tube.
Background technology
The electric heating pipe component that the auxiliary heating of common electrically heated boiler and steam generator is used in the market adopts the compositions such as steel flange 1 and single or multiple stainless steel electrical heating tube elements 2, as shown in Figure 2, then by scolder, steel flange 1 and stainless steel electrical heating tube element 2 are welded to the electric heating pipe component of making, as shown in Figure 1.The electric heating pipe component that is applied to boiler industry due to the large surface loading of power is high and long-term work in the environment of high temperature, high pressure, the impact of the hardness that is simultaneously subject to water quality on electrical heating tube element 2, easily fouling, cause a certain group of electrical heating tube element 2 local overheatings in electric heating pipe component to be damaged, causing boiler capacity to reduce affects industrial production.User can only change a whole set of electric heating pipe component or be followed and changed the electrical heating tube element 2 damaging in electric heating pipe component by professional and technical personnel after realizing self disassembling flange, to user, brought great inconvenience, the a whole set of replacing of electric heating pipe component not only caused raw-material waste, also increases user's operation and maintenance cost.
Utility model content
Technical problem to be solved in the utility model is: a kind of flange form electric heating tube that need not change a whole set of electric heating pipe component and be convenient to non-specialized-technical personnel's mounting or dismounting is provided.
For addressing the above problem, the technical solution adopted in the utility model is: a kind of flange form electric heating tube, comprise a flange and at least one electrical heating tube element, on described flange internal flange face, offer for plugging the through hole of electrical heating tube element, one end that described electrical heating tube element is used for plugging is provided with fastening bolt, fastening bolt inside offers bolt hole, one end that described electrical heating tube element is used for plugging is stretched in the bolt hole of fastening bolt and is interfixed, one end of described fastening bolt is stretched in the through hole of flange face and the through hole of emerging, described fastening bolt therewith through hole matches, emerge of flange face through hole of described fastening bolt is provided with clamp nut.
Preferably, the through hole end on described flange face is provided with concave station.
Preferably, described concave station place is provided with sealing ring.
Preferably, described electrical heating tube element and fastening bolt are fixedly connected by welding.
Preferably, described flange, electrical heating tube element, fastening bolt, clamp nut, welding material are stainless steel.
The beneficial effects of the utility model are: the fastening bolt of opening bolt hole by having increased a centre, thereby changed the directly connected mode of welding of original electrical heating tube element and flange, electrical heating tube element is first welded with fastening bolt, by fastening bolt, with sealing ring, electrical heating tube element is connected with flange seal again, this connected mode can be suitable for non-specialized-technical personnel and remove and install, improved the flexibility that electrical heating tube element is installed, user need not change whole group of electric heating assembly, only need dismounting single electric heating element wherein, for the user with the blue formula electric heating steam boiler of multigroup method, can reduce greatly raw-material waste, reduce the cost using.
