A gas welding nozzle with controllable nozzle size

Abstract

The invention relates to the technical field of gas welding tools, and discloses a gas welding spray head capable of controlling the size of the nozzle, including a gun housing, a fuel port is opened on the left side of the gun housing, and a fuel switch is fixedly connected to the left side of the fuel port. There is an oxygen port on the left side of the gun, an oxygen switch is fixedly connected to the left side of the oxygen port, a heat insulation pad is fixedly connected to the bottom of the gun shell, and a mixing box is fixedly connected to the bottom of the heat insulation pad. The gas welding nozzle that can control the size of the nozzle, The support frame is fixedly connected to the rod groove, the upper part of the support frame is fixedly connected with bolts, and the bolts are used to cooperate with the screw rod. The end of the screw rod away from the bolt is fixedly connected with the upper nozzle, and the upper end of the upper nozzle is fixedly connected with a spring. There is a baffle on the left side of the spring, and the baffle is used to control and adjust the maximum of the upper nozzle. By twisting the screw and the bolt, the upper nozzle can be adjusted up and down, so as to achieve the effect of adjusting the size of the nozzle.

Description

technical field [0001] The invention relates to the technical field of gas welding tools, in particular to a gas welding nozzle capable of controlling the size of a nozzle. Background technique [0002] Gas welding is a welding method that uses the flame generated by the mixed combustion of combustible gas and combustion-supporting gas as a heat source to melt the weldment and welding materials to achieve interatomic bonding. With the rapid development of my country's industrial level, gas welding guns are widely used in many industrial production bases. The emergence of gas welding provides great convenience for the staff. Gas welding plays a pivotal role in the welding field. With the popularization of gas welding, It plays an important role in people's life. The nozzle is one of the most important components of the gas welding torch. During the welding process, the quality of the welding mostly depends on the quality of the nozzle. [0003] At present, there are many kind...
