Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] The atomizing nozzle provided by the present invention includes a nozzle body 1 with a channel, and a rotating head 10 with a cavity and a spout 7 on the nozzle body 1 is provided with it, wherein the cavity inlet on the rotating head 10 The section is set as a columnar cavity 11, the outlet section is set as a conical cavity 8, the conical cavity 8 communicates with the spout 7, the outlet end of the nozzle body 1 is set as a columnar body 3 that is matched with the rotating head 10, and the columnar body 3 passes through the opening of its outer wall. The screw thread is connected with the inner wall thread of the cylindrical cavity 11 of the rotating head 10. The axial passage 2 is arranged in the cylindrical body 3, and the radial passage 5 at the end of the cylindrical body communicated with the axial passage 2, and the outlet end of the cylindrical body 3 ...

Abstract

The invention provides an atomizing nozzle and a hand-hold atomization gas quenching device with the atomizing nozzle, comprising a handle which is internally provided with a gas channel and a liquid channel, and a spraying pipe which is internally provided with a mixed gas channel which is communicated with the gas channel and the liquid channel, and is connected with the handle; the hand-hold atomization gas quenching device is characterized in that: the atomizing nozzle is connected at the end part of the spraying pipe and is provided with a nozzle body with a channel and a rotating head which is matched with the nozzle body and is provided with a cavity and a jet opening; the original way that the gas quenching or the liquid quenching is carried out independently is changed into the way that the gas quenching and liquid quenching are carried out at the same time, thereby having the advantages of liquid quenching and gas quenching; in addition, the device does not need a huge supporting facility and is only matched with a small device, so as to save a great amount of cost and investment for users; in addition, the carrying and usage are convenient, therefore, the hand-hold atomization gas quenching device with the atomizing nozzle is an ideal quenching device.

Description

technical field [0001] The invention relates to an atomizing nozzle and a quenching device with the nozzle, in particular to a hand-held gas quenching device with an atomizing nozzle, which belongs to the technical field of heat treatment equipment. technical background [0002] At present, the known quenching media mainly include water, gas and oil. However, after the quenching treatment of these media, there will be defects in different degrees on the surface of the workpiece, which makes it difficult for the workpiece to meet the inspection standards and use standards after quenching, and the above quenching Among the methods, the speed of gas quenching is too slow, the speed of water quenching is too fast, and the speed of oil quenching is too expensive, resulting in different quenching methods for different workpieces. However, the existing quenching devices generally have the problem of relatively large volume, and in order to meet the requirements of different quenchi...
