Abstract
The utility model provides a water connector for electromagnetic stirrers, which comprises a compression nut, a copper-made pipe connector that is in threaded fit with the compression nut, a shrink sleeve which is arranged inside the compression nut, and a sealing gasket and a polytetrafluoro pipe connector which are arranged inside the compression nut and positioned between the copper-made pipe connection and the shrink sleeve. The water connector has the characteristics of high mechanical strength, no leakage at high temperature and high pressure and high compressive resistance up to 46kg/cm<2>, and is mainly used, as the pipe connection, for hollow copper pipe internal cooling-type electromagnetic stirrers adopted by bloom casters.
Description
Technical field
The utility model relates to a kind of pipe coupling, particularly relates to a kind of water swivel of magnetic stirrer.
Background technique
At present, the hollow copper tubing inner-cooling type electromagnetic stirrer that domestic each big steel company generally adopts Sweden ABB AB to manufacture and design on large square bland continuous-casting machine, wherein the water swivel that adopts on this magnetic stirrer is made up of copper nut, copper pipe joint and copper shrink sleeve three parts.This water swivel is less at pipeline diameter, water leakage phenomenon can not occur when hydraulic pressure is high, but it is bigger to work as pipeline diameter, when hydraulic pressure is higher, because the mechanical strength of copper material is low, therefore, can not tighten gland nut, thereby can not make shrink sleeve compress plastic conduit with the moment wrench, otherwise, can damaged screw.The aspect along with increase service time, after using about 1 year, owing to high temperature, high pressure effect, micro gap can occur between plastic conduit and shrink sleeve in addition, causes the joint water leakage phenomenon to occur.
The model utility content
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of simple in structure, easily manufactured, and the mechanical strength height, the water swivel that is used for magnetic stirrer that High Temperature High Pressure is non-leakage.
The water swivel that the utility model is used for magnetic stirrer comprises gland nut, copper pipe joint with the gland nut screw-thread fit, be arranged on the shrink sleeve in the gland nut, and be arranged in the gland nut and seal washer between copper pipe joint and shrink sleeve and poly-four fluorine tube joint.Wherein, the leading portion of gland nut is an outer-hexagonal shape, and interior is fine thread, and back segment is inside and outside to be conical; Shrink sleeve is the tyre tapering, and interior is the tapered sleeve structure of rectangle alveolus, and 10 ° of breach are arranged along its length; Poly-four fluorine tube joint is the tubulose that has the shaft shoulder, and excircle is the structure of rectangle alveolus.
Its working principle of water swivel that the utility model is used for magnetic stirrer is, during use, the copper pipe joint is welded on the copper pipe to be connect, the polytetrafluoroethylplastic plastic pipe encapsulation that certain-length is to be connect is between poly-four fluorine tube joint and shrink sleeve, again the two is put in the gland nut, seal ring on the pad, tighten the screw thread of gland nut and copper pipe joint, at this moment, shrink sleeve because of elastic shrinkage will be to be connect the polytetrafluoroethylplastic plastic tube wall be pressed between poly-four fluorine tube joint and the shrink sleeve, copper pipe joint end face is realized sealing by seal ring.
The utility model is used for the water swivel of magnetic stirrer, and its advantage is simple in structure, and is easy to assembly, the mechanical strength height, and high temperature, high pressure are impermeable.Be mainly used in the hollow copper tubing inner-cooling type electromagnetic stirrer that adopts on the large square bland continuous-casting machine, use as pipe joint.

Embodiment
The water swivel that the utility model is used for magnetic stirrer comprises gland nut 1, copper pipe joint 2 with gland nut 1 screw-thread fit, be arranged on the shrink sleeve 5 in the gland nut 1, and be arranged in the gland nut 1 and seal washer between copper pipe joint 2 and shrink sleeve 53 and poly-four fluorine tube joint 4.Wherein, the leading portion of gland nut 1 is an outer-hexagonal shape, and interior is fine thread, and back segment is inside and outside to be conical; Shrink sleeve 5 is tyre taperings, and interior is the tapered sleeve structure of rectangle alveolus, and 10 ° of breach are arranged along its length; Poly-four fluorine tube joint 4 is outer tubuloses that have the shaft shoulder, and excircle is the structure of rectangle alveolus.
Claims (2)
1. water swivel that is used for magnetic stirrer, comprise gland nut, copper pipe joint with the gland nut screw-thread fit, and be arranged on the interior shrink sleeve of gland nut, it is characterized in that being provided with in the gland nut seal washer and poly-four fluorine tube joint between copper pipe joint and shrink sleeve.
2. the water swivel that is used for magnetic stirrer according to claim 1, the leading portion that it is characterized in that gland nut is an outer-hexagonal shape, and interior is fine thread, and back segment is inside and outside to be conical; Shrink sleeve is the tyre tapering, and interior is the tapered sleeve structure of rectangle alveolus, and 10 ° of breach are arranged along its length; Poly-four fluorine tube joint is the tubulose that has the shaft shoulder, and excircle is the structure of rectangle alveolus.
