Abstract
The utility model discloses a novel high pressure spray head. The utility model is characterized in that a soldering seat is provided with an inner catheter made of brass and a filter; the inner catheter is provided with a straightener blade made of copper alloy; lower part of the soldering seat is provided with a blow head housing; the blow head housing is provided with a hard alloy blow head and its cover; the blow head housing uses cap nuts to fix the soldering seat by screws. For hot-rolled steel billets and steel plates, the utility model uses water as medium ejected onto hot steel plate surfaces, and the temperature difference between water and steel plates form heat power, and water cools oxide layer on surface of steel plate, thus the apparent temperature difference of the steel plates causes check crack to achieve descaling effect in process of rolling operation. The utility model mainly utilizes the filter and the current regulator hard alloy blow head to make water at the blow head generate pressure of 150-300 bar in order to attack steel billets and steel plates, achieving descaling in rolling operation for steel billets and steel plates and improving quality of steel plates consequently.
Description
Technical field
The utility model relates to a kind of shower nozzle, especially has very a kind of novel high-pressure shower nozzle of the high-pressure water jet of strong impact force, this shower nozzle is in hot steel billet, steel plate, utilize water to be medium, high-pressure injection is to the surface of steel billet, steel plate, the temperature difference of water and steel plate formation heat power, water cooling the oxide skin of surface of steel plate, thereby the surface of steel plate temperature difference causes and shrinks fracture, is issued to the effect of removal oxide skin in the operation of rolling in the impact of high pressure.
Background technology
At steel billet, steel plate.In the rolling process, the surface of its steel part can produce iron scale, and oxide skin is adsorbed on the surface of steel plate, will seriously influence the surface quality of steel plate.At present, the way of external scale removal is the injection by water under high pressure, but often can't rinse owing to the jet power deficiency.Thereby influence plate quality.Existing domestic technique nozzle structure is simple, because unreasonable structure, hitting power is little and inhomogeneous, concentrated, the iron scale of steel piece surface thoroughly can not be rooted out totally.Because material is selected unreasonablely, and make shower nozzle very short service life, only be 1～3 month in addition.
Summary of the invention
The purpose of this utility model provides a kind of very a kind of novel high-pressure shower nozzle of the high-pressure water jet of strong impact force that has at the deficiency that on the existing nozzle structure and material selection aspect exists.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel high-pressure shower nozzle comprises filter, flow straightener, weldering seat, nut, the carbide alloy shower nozzle.It is characterized in that in the weldering seat copper material inner catheter and filter being housed; In the straightener(stator) blade of copper alloy material is housed in leading; Nozzle housing is equipped with in weldering seat lower end; Carbide alloy shower nozzle and cover are housed in the nozzle housing body; Nozzle housing is to be integrated with the screw thread handle with nut and weldering seat.
Shower nozzle of the present utility model adopts carbide alloy, and inner catheter, filter, rectifier are copper, copper alloy material.The structure of the shower nozzle of carbide alloy, inner catheter rectifier and Material Selection make water quality reach the impulsive force of 150～300bar, improve simultaneously more than shower nozzle whole service life 2-3 times.
The utility model is on the basis of existing high-pressure nozzle, be provided with and the fairing that synthesizes by the filter set of inner catheter, copper alloy rectifier and copper material, thereby make water under high pressure water be changed fluid state through fairing, again after the pyramidal contraction of four convergences forward, spray at a high speed by the elliptical shape spout, form 150～300bar High-Pressure Water, such High-Pressure Water can thoroughly be rooted out iron scale in the process of steel billet, steel plate rolling effectively, make steel part be pure true qualities, guarantee the quality of steel part.Structure that the utility model is new reasonable and rational selection of material result of use are splendid.Be that very strong practicality is arranged.
Description of drawings
Fig. 1 is the utility model structural front view;
Fig. 2 is the cutaway view of Fig. 1
Among the figure, the 1st, nut, the 2nd, weldering seat, the 3rd, filter, the 4th, carbide alloy shower nozzle, the 5th, cover, the 6th, rectifier, the 7th, inner catheter, the 8th, nozzle housing.
The specific embodiment
The utility model is based on existing high-pressure nozzle, promptly comprises nozzle housing 8, with the screw thread inner catheter that spins.On 7, with nozzle housing 8, be fixed on the weldering seat 2 with screw thread, carbide alloy shower nozzle 4 and cover 5 are housed in the nozzle housing body 8, be fixed on the nozzle housing body by inner catheter 7, in the cavity of inner catheter 7 ends, in lead the rectifier 6 that special substance is equipped with in interference in 7 chambeies, there is external screw thread that the filter 3 of copper material is spun outside the inner catheter 7, forms an integral body.
The utility model is on the basis of existing high-pressure nozzle, be provided with and the fairing that is combined into by the filter 3 of inner catheter 7, copper alloy rectifier 6 and copper material, thereby make water under high pressure water be changed fluid state through fairing, again after the pyramidal contraction of four convergences forward, spray at a high speed by the elliptical shape spout, form 150～300bar High-Pressure Water, such High-Pressure Water can thoroughly be rooted out iron scale in the process of steel billet, steel plate rolling effectively, make steel part be pure true qualities, guarantee the quality of steel part.Structure that the utility model is new reasonable and rational selection of material result of use are splendid.Be that very strong practicality is arranged.
