The utility model has the advantages that: the cross water tank is arranged in the cone, water flow is sprayed out after passing through the water tank to form a spray shape, and the spray steel plate covering effect is facilitated.
Description
Technical Field
The utility model relates to a nozzle, in particular to a nozzle for a heat treatment furnace.
Background
The heat treatment of large-sized steel plates requires water spraying on both sides of upper and lower press heads of heat treatment equipment in order to quench the steel plates. The nozzle structure in the prior art is used for spraying water by drilling a small hole with the diameter of 1mm on a pressure head by using a drill bit, but the small hole is easy to block due to small diameter and small spraying area, so that the surface of a steel plate is easy to partially and incompletely quench.
Disclosure of Invention
In order to solve the technical problem, the utility model aims to provide a conjoined wide-angle conical nozzle, which comprises a body, wherein a rotating cap is fixed at the outer side of the middle of the body, one side of the rotating cap is a spray head, and the other side of the rotating cap is a water inlet cavity; the outer side of the water inlet cavity is provided with threads, and the inner cavity wall of the water inlet cavity is provided with two water tanks which form an included angle of 60-75 degrees with each other; a mixing cavity is arranged between the water inlet cavity and the spray head, and the connecting end of the mixing cavity and the spray head is a conical section; the spray head comprises a cylindrical section connected with the mixing cavity, and the cylindrical section is connected with the arc-shaped section; and a flow breaking groove is also arranged on the outer side of the arc-shaped section.
The length of the cylindrical section on the horizontal plane is 1.5-2 times of the length of the circular arc section on the horizontal plane. The included angle of the taper section is 115 degrees and 125 degrees.
The utility model has the advantages that: the nozzle is fixed on the pressure head through threads, and water flow in the pressure head is sprayed to the surface of the steel plate through the nozzle to finish the quenching treatment process of the steel plate. The diameter of the nozzle is 3.2mm, the spraying wide angle is 120 degrees, the purpose of completely covering the surface of the steel plate can be achieved, and the whole nozzle is made of stainless steel and is not easy to rust and corrode to cause blockage. The cross water tank is arranged in the cone, water flow is sprayed out after passing through the water tank to form a spray shape, and the spray steel plate covering effect is facilitated.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The utility model is described in detail with reference to the drawings, as shown in the figures, the utility model comprises a body 1, a rotating cap 2 is fixed on the outer side of the middle of the body, a wrench can be used to screw or loosen a nozzle by using the rotating cap, one side of the rotating cap is a spray head 3, and the other side is a water inlet cavity 4; the outer side of the water inlet cavity is provided with a thread 9, the thread 9 is used for being connected with a spray head, and a groove 10 is arranged at the connecting end for placing a sealing ring; in order to ensure that the sprayed water is in smaller particles, two water tanks are arranged on the inner cavity wall of the water inlet cavity 4, namely a first water tank 41 and a second water tank 42, and the included angle a between the first water tank 41 and the second water tank 42 is 60-75 degrees, wherein if the included angle is too small, the spraying speed is affected, and if the included angle is too large, the atomization effect is affected; a mixing cavity 5 is arranged between the water inlet cavity 4 and the spray head 3, and the connecting end of the mixing cavity and the spray head is a conical section 6; because the two water tanks form a certain included angle, the water in the two water tanks can collide with each other in the mixing cavity to be split into smaller particles;
the spray head 3 comprises a cylindrical section 7 connected with the mixing cavity, and the cylindrical section is connected with an arc-shaped section 8; the central angle corresponding to the circular arc section is 90 degrees, namely 1/4 circular arcs;
in order to prevent water from forming water drops from the edge of the spray head when water is sprayed, and further influence the quenching effect, the outer side of the arc-shaped section 8 is also provided with a flow breaking groove 11, and the arrangement can ensure that water with a certain speed cannot flow from one end of the flow breaking groove to the other end;
the length m of the cylindrical section on the horizontal plane is 1.5-2 times of the length n of the circular arc section on the horizontal plane. An excessively long cylindrical section affects the atomization effect, and an excessively short circular arc section affects the dispersion effect; the taper included angle b of the taper section is 115 degrees and 125 degrees, the water flow jet speed can be reduced when the angle is too large, the jet area can be reduced when the angle is smaller, and the numerical range is adopted in comprehensive consideration.
When the quenching device is used, the nozzle is fixed on the pressure head through threads, and water flow in the pressure head is sprayed to the surface of the steel plate through the nozzle to finish the quenching treatment process of the steel plate.
Claims (3)
