Description
Technical field
The utility model relates to a kind of heat spray degree device, especially a kind of lance head made from stupalith that is used for thermospraying zinc.
Background technology
At present, the aseptic technic on the surface of steel pipe is pot galvanize basically, and this technology is ripe basically.This method is applied to the anticorrosion of cast iron pipe appearance, does not also have the report of success at present.But, at present both at home and abroad more and more higher to the requirement for anticorrosion of cast iron pipe outside surface, get around pot galvanize and adopt thermospraying zinc technology that the technology of cast iron pipe outside surface anticorrosion with painting zinc coating is arisen at the historic moment.Producing a kind of lance head that can use for a long time, is the technical problem of being badly in need of solution at present.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of lance head that can use for a long time.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of lance head, lance head body by insulating material, last lance tube, following lance tube and pressure ventilation pipe joint, described lance head body is made of the cylinder of right part and the cone table of left part, there is the taper type pit at middle part at lance head body right part, the conical surface of taper type pit is parallel with the conical surface of the cone table of lance head body left part, there is ventilation hole at middle part at the lance head body, the left side of ventilation hole is processed with internal thread for half section, the lance tube open holes that oblique layout is all arranged in the upper and lower of ventilation hole, the lance tube open holes is vertical with the conical surface of the cone table of lance head body left part with the conical surface of taper type pit, and the cylinder of the cylinder part of rifle head body is provided with the mounting groove with rifle body coupling.
As optimal technical scheme of the present utility model, lance head body described in the utility model is made by stupalith.
As the further optimal technical scheme of the utility model, the left end of pressure ventilation pipe joint described in the utility model is processed with air-hose anticreep serrated slot, the right part of pressure ventilation pipe joint is processed with the outside screw with the internal thread coupling on half section on a described ventilation hole left side, and the pressure ventilation pipe joint is threaded with the lance head body.
As the further again optimal technical scheme of the utility model, the lance tube of going up described in the utility model is the same with following lance tube shape and size and make by metallic substance, the external diameter of its right-hand member head is greater than the external diameter of other parts, be processed with outside screw in the left part, last lance tube and following lance tube are installed in the upper and lower lance tube open holes, and its upper end is installed with set nut.
As the technical scheme of the utility model the best, the through hole of going up lance tube and following lance tube center of the present utility model, the diameter of its left end is greater than the diameter of right-hand member.
Because lance head body of the present utility model has adopted stupalith, thus high temperature resistant especially, can be fit to than the demand of major diameter zinc silk to big electric current, long service life.
