Abstract
The invention relates to a flange type electrical heating pipe. The flange type electrical heating pipe comprises a flange and at least one electrical heating pipe element, wherein a through hole used for the electrical heating pipe element to be inserted is formed in the flange surface inside the flange; a fastening bolt is arranged at one end, used for inserting, of the electric heating pipe element; a through hole is formed in the fastening bolt; one end, used for inserting, of the electric heating pipe element stretches into the through hole of the fastening bolt, and the electric heating pipe element and the through hole are fixed; one end of the fastening bolt stretches out of the through hole of the flange surface; the fastening bolt is matched with the through hole of the flange surface; a fastening nut is arranged at one head, stretching out of the flange surface, of the fastening bolt. According to the invention, the flange type electrical heating pipe is suitable for non-professional technicians to dismount and mount, the electric heating pipe element is mounted more flexibly; users don't need to replace the whole group of electric heating elements but only to dismount single electric heating elements; raw materials can be greatly saved for users who own multigroup flange type electric heating steam boilers, and the utilization cost is reduced.
Description
Technical field
The present invention 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.
Summary of the invention
Technical problem to be solved by this invention 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 used in the present invention 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 invention has the beneficial effects as follows: 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.

Embodiment
Below in conjunction with accompanying drawing, by specific embodiment, the invention will be further described.
As shown in Figure 3, described a kind of flange form electric heating tube, comprise a flange 1 and at least one electrical heating tube element 2, on described flange 1 internal flange face, offer for plugging the through hole 11 of electrical heating tube element 2, as shown in Figure 4, through hole 11 ends are provided with concave station 12, described concave station 12 places are provided with sealing ring 3, one end that described electrical heating tube element 2 is used for plugging is provided with fastening bolt 4, fastening bolt 4 inside offer bolt hole, one end that described electrical heating tube element 2 is used for plugging is stretched in the bolt hole of fastening bolt 4 and is interfixed by welding, one end of described fastening bolt 4 is stretched in the through hole 11 of flange face and the through hole 11 of emerging, described fastening bolt 4 therewith through hole 11 matches, emerge of flange face through hole 11 of described fastening bolt 4 is provided with clamp nut 5, described flange 1, electrical heating tube element 2, fastening bolt 4, clamp nut 5, welding material is stainless steel.
The present invention drives the fastening bolt 4 of bolt hole by having increased a centre, thereby original electrical heating tube element 2 and the direct connected mode of welding of flange 1 have been changed, electrical heating tube element 2 is first welded with fastening bolt 4, by fastening bolt 4 and sealing ring 3, electrical heating tube element 2 and flange 1 are tightly connected again, this connected mode can be suitable for non-specialized-technical personnel and remove and install, improved the flexibility that electrical heating tube element 2 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.
The present invention is not limited to above-mentioned execution mode, no matter do any variation in its shape or material formation, every employing structural design provided by the present invention, is all a kind of distortion of the present invention, all should think within protection range of the present invention.
