Embodiment Construction

[0042] Such as Figure 10 As shown, the torch equipment of the present invention includes an oxygen supply solenoid valve A1 and a gas supply solenoid valve A2 respectively arranged on the oxygen supply pipeline and the combustible gas supply pipeline. Among them, the electrical control part includes:

[0043] The fifth time relay KT5 is used to control the delayed closing of the oxygen supply solenoid valve A1 during fire extinguishing; wherein, the solenoid valve A1 is connected to the power supply through the contact switch of the fifth time relay KT5;

[0044]The seventh time relay KT7 is used to control the gas supply solenoid valve A2 to close immediately during fire extinguishing; wherein, the solenoid valve A2 is connected to the power supply through the contact switch of the fifth time relay KT7;

[0045] The gas control switch K3 is a switch for connecting the fifth time relay KT5 and the seventh time relay KT7 to power.

[0046] When the torch is ignited, the gas ...

Abstract

The invention discloses a using method of baking torch equipment. When fire is extinguished and the equipment is switched off, the valve of an oxygen supply pipeline is closed lagging behind the timing closing of the valve of a flammable gas supply pipeline, supplying of oxygen and flammable gas is cut off, and therefore using safety of the baking torch is guaranteed. The invention further provides equipment for achieving the method, and operation is made to be easier and more reliable through relay switches. In addition, the invention further provides a back burning machine for shipbuilding and facilitating control, the back burning machine for the shipbuilding is equipment specifically using the method. The back burning machine for the shipbuilding can achieve back burning of ship steel structures effectively and automatically in a building process, meets production requirements of ships, improves back burning quality and efficiency, is beneficial to improving the building precision of the ship steel structures, and has the advantages of being low in cost, high in working efficiency, long in service life and the like.

Description

technical field [0001] The present invention relates to a torch equipment, more specifically, to the improvement of the gas supply system of the torch equipment. Background technique [0002] During the shipbuilding process, the accuracy control and the orderliness and appearance of the outer plate are very important aspects to ensure the quality of the shipbuilding and win the reputation of the shipowner, and one of the important factors affecting the precision of the shipbuilding is the welding deformation of the hull. Hull welding deformation is a common phenomenon in the shipbuilding process. After the hull is deformed, it will affect the accuracy and quality of the overall construction of the ship, and affect the appearance of the ship. The welding deformation of the hull can be reduced through pyrotechnic correction, but due to the huge workload, Most of the cutting requires workers to look up to work, and the workload is heavy. Due to the above reasons, the work cycle...
