Shower nozzle.
The technical solution of the utility model is: a kind of coverter pig makes steel oxygen gun sprayer, and it includes: oxygen feeding tube, water inlet pipe, leads
Water plate, outlet pipe and nozzle cap；
The outlet side of oxygen feeding tube is welded with oxygen shunt head, and the lower surface center position of oxygen shunt head is provided with Shang Fenshui
Cone, is provided with, on the oxygen shunt head around upper point of water cone, the oxygen outlet connecting with oxygen feeding tube；
Water inlet pipe noose, in the outside of oxygen feeding tube, has weather board in the bottom welding of water inlet pipe, and weather board has centre bore,
And inside and outside wall is in arc transition；
Outlet pipe noose, in the outside of water inlet pipe, has nozzle cap in the bottom welding of outlet pipe, and the center of nozzle cap sets
Have and upper point lower point of relative water cone of water cone, around lower point of water cone, be provided with oxygen spraying hole；In the shower nozzle with outlet pipe seam
It is provided with point water at lid to split；Divide water to split to be arranged between adjacent oxygen spraying hole, front projection is the sector of camber line for both sides, its bottom surface
Fit with the bottom surface of nozzle cap, top surface arc transition；
Laval nozzle connects oxygen outlet and oxygen spraying hole.
Beneficial effect: this utility model accelerates flow of cooling water, reaches more preferable cooling-down effect, thus improving coverter pig
The life-span of steel-making oxygen rifle.
(1) weather board can improve the cooling water of existing oxygen rifle and flows not smooth situation at weather board it is ensured that cooling system
When system reaches stable state, cooling water average rate, smooth entrance shower nozzle position after weather board.
(2) divide water to split and can largely reduce cooling water " dead band " scope, from actual field situation, shower nozzle glues
The position of steel most serious is the corresponding position of cooling water " dead band ", and the interpolation that Gu Fenshui splits can largely improve oxygen rifle
In rifle age, reduce and change rifle frequency, substantially reduce production cost, reach considerable using effect.
Brief description
Fig. 1 is this utility model structural representation；
Fig. 2 is the partial enlarged drawing that in this utility model, point water is split；
Fig. 3 is the upward view of Fig. 1.
Specific embodiment
Referring to accompanying drawing, a kind of coverter pig makes steel oxygen gun sprayer, and it includes: oxygen feeding tube 1, water inlet pipe 2, weather board 4, outlet pipe
5 and nozzle cap 10；
The outlet side of oxygen feeding tube 1 is welded with oxygen shunt head 7, and the lower surface center position of oxygen shunt head 7 is provided with
Divide water cone 6, the oxygen shunt head 7 around upper point of water cone 6 is provided with the oxygen outlet connecting with oxygen feeding tube 1；
Water inlet pipe 2 noose, in the outside of oxygen feeding tube 1, has weather board 4 in the bottom welding of water inlet pipe 2, during weather board 4 has
Heart hole, and inside and outside wall is in arc transition；
Outlet pipe 5 noose, in the outside of water inlet pipe 2, has nozzle cap 10 in the bottom welding of outlet pipe 5, in nozzle cap 10
It is provided with the heart and upper point lower point of relative water cone 8 of water cone 6, around lower point of water cone 8, be provided with oxygen spraying hole 3；Connecing with outlet pipe 5
It is provided with point water at nozzle cap 10 at mouthful and split 11；Divide water to split 11 to be arranged between adjacent oxygen spraying hole 3, front projection for both sides is
The sector of camber line, fitted with the bottom surface of nozzle cap 10 in its bottom surface, top surface arc transition；
Laval nozzle connects oxygen outlet and oxygen spraying hole 3.
The outer wall of oxygen feeding tube 1 is provided with annular seal groove 2, and oxygen rifle oxygen deliverng pipe passes through " o " type sealing ring with oxygen feeding tube 1 sealing even
Connect it is ensured that oxygen channel smooth while also allow for dismantle.
Further, oxygen spraying hole 3, nozzle cap 10, down point water cone 8 and point water split 11, above divide water cone 6 and oxygen shunting
7 are global formation, and middle no-welding-seam decreases and substantially increases the tight of oxygen gun sprayer each several part while steel consumption
Connected degree, and the evenness of wall thickness of each several part and the slickness of inside and outside wall, thus improve its heat conductivility and oxygen rifle
The ruggedness of shower nozzle.
Work process is: when high pressure oxygen stream is after oxygen feeding tube 1 entrance, is disperseed to oxygen spraying hole 3 by oxygen shunt head 7
