Abstract
A kind of porcelain tube formula water-cooled resistance of the utility model, including porcelain tube and the resistance wire for being wrapped in porcelain tube outer surface, the both ends of porcelain tube are designed with sealed rubber ring and ring end cap, and sealed rubber ring coats the end of porcelain tube, and ring end cap is buckled in outside sealed rubber ring；It is provided with mounting hole and liquid-passing hole in the middle part of ring end cap, screw rod is installed in porcelain tube, the end of screw rod is secured with nuts after the mounting hole of ring end cap, so that the ring end cap at porcelain tube both ends mutually tenses；Ring end cap is connected with logical liquid connector, and logical liquid connector is connected to by the liquid-passing hole with the inside of porcelain tube, seals between the side wall and ring end cap of logical liquid connector.Compared with prior art, the porcelain tube formula water-cooled resistance of the utility model, without the periphery tapping in porcelain tube, also would not the fragile problem of ceramic thread convenient for manufacture save cost.The sealing between porcelain tube and the external world is realized using sealed rubber ring and ring end cap, sealing effect is good.
Description
Technical field
The utility model relates to resistive technologies fields, and in particular to a kind of porcelain tube formula water-cooled resistance.
Background technique
The resistance wire that water-cooled resistor generally comprises porcelain tube and is wound on porcelain tube, the both ends of porcelain tube are separately connected water supply connector
And water outlet connector, the heat generated when resistance wire work is taken away by the liquid of the internal flow in porcelain tube.To ensure to insulate,
The resistance wire of the impermeable outer surface to porcelain tube of circulating liquid inside porcelain tube, so the company between disengaging water swivel and porcelain tube
More key is connect, general at present in such a way that disengaging water swivel is threadedly coupled with porcelain tube, ceramics open screw thread complex process, and make pottery
Porcelain is frangible, and thread is fragile during the fastening process, influences the leakproofness of resistance.
Summary of the invention
For the prior art there are above-mentioned technical problem, the utility model provides a kind of porcelain pipe-type water-cooling of good seal performance
Resistance.
To achieve the above object, the utility model the following technical schemes are provided:
A kind of porcelain tube formula water-cooled resistance is provided, including porcelain tube and the resistance wire for being wrapped in porcelain tube outer surface, the both ends of porcelain tube
Portion is designed with sealed rubber ring and ring end cap, and sealed rubber ring coats the end of porcelain tube, and ring end cap is buckled in outside sealed rubber ring；Ring end cap
Middle part is provided with mounting hole and liquid-passing hole, and screw rod is installed in porcelain tube, and the end of screw rod is solid with nut after the mounting hole of ring end cap
It is fixed, so that the ring end cap at porcelain tube both ends mutually tenses；Ring end cap is connected with logical liquid connector, leads to liquid connector and passes through the liquid-passing hole
It is connected to the inside of porcelain tube, is sealed between the side wall and ring end cap of logical liquid connector.
Wherein, porcelain tube is alumina ceramic tube.
Wherein, washer is equipped between nut and ring end cap, washer covers outside screw rod.
Wherein, ring end cap is metal cover.
The utility model has the beneficial effects that
Compared with prior art, the porcelain tube formula water-cooled resistance of the utility model, without the periphery tapping in porcelain tube, also
Will not the fragile problem of ceramic thread convenient for manufacture save cost.It is realized using sealed rubber ring and ring end cap at porcelain tube nozzle
Sealing between the external world, sealing effect are good.

Specific embodiment
The utility model is described in detail below in conjunction with specific embodiments and drawings.
A kind of porcelain tube formula water-cooled resistance of the present embodiment, as depicted in figs. 1 and 2, including oxidation aluminium material porcelain tube 1 and winding
Resistance wire in 1 outer surface of porcelain tube, the both ends of porcelain tube 1 are designed with the ring end cap 3 of sealed rubber ring 2 and metal material, sealant
Ring 2 coats the inside and outside wall of the port of porcelain tube 1, and ring end cap 3 is buckled in outside sealed rubber ring 2 and closely coats the outer of sealed rubber ring 2 completely
Side.In conjunction with shown in Fig. 3 and Fig. 4, the middle part of ring end cap 3 is provided with a mounting hole 31 and six liquid-passing holes 32, is installed with spiral shell in porcelain tube 1
The end of bar 4, screw rod 4 is fixed with nut 5 after the mounting hole 31 of ring end cap 3, so that 3 phase of ring end cap at 1 both ends of porcelain tube
It mutually tenses, washer 7 is equipped between nut 5 and ring end cap 3,7 sets of washer outside screw rod 4.Ring end cap 3 is threaded with logical liquid connector
6, what logical liquid connector 6 was connected to by liquid-passing hole 32 with the inside of porcelain tube 1, the logical liquid connector 6 at 1 both ends of porcelain tube is respectively as water inlet
And water outlet, water flow is formed in porcelain tube 1, takes away heat.
Compared with prior art, the present embodiment is not necessarily to the periphery tapping in porcelain tube 1, also would not ceramic thread it is frangible
Problem saves cost convenient for manufacture.Sealing is realized between porcelain tube 1 and ring end cap 3 by sealed rubber ring 2, lead to liquid connector 6 with
Ring end cap 3 is all metal material, the favorable sealing property being threadedly coupled between the two and the relatively stable fixation of the two, formed according to
It is secondary by inside porcelain tube 1, liquid-passing hole 32 and logical liquid connector 6 channel unique in this way.In addition, compared to traditional resistor screw rod 4 from
The structure that 1 both ends of porcelain tube are pierced by, the screw rod 4 of the present embodiment are accommodated in inside completely, screw rod 4 at a distance from resistance wire farther out, spiral shell
Bar 4 will not reduce insulation performance.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
