本发明涉及高温焊接技术领域，具体为一种焊接用耐高温设备。The invention relates to the technical field of high-temperature welding, in particular to high-temperature-resistant equipment for welding.
背景技术Background technique
焊接，也称作熔接，是一种以加热、高温或者高压的方式接合金属或其他热塑性材料如塑料的制造工艺及技术。现代焊接的能量来源有很多种，包括气体焰、电弧、激光、电子束、摩擦和超声波等。除了在工厂中使用外，焊接还可以在多种环境下进行，如野外、水下和太空。无论在何处，焊接都可能给操作者带来危险，所以在进行焊接时必须采取适当的防护措施。Welding, also known as welding, is a manufacturing process and technique that uses heat, high temperature, or pressure to join metal or other thermoplastic materials such as plastics. There are many sources of energy for modern welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. In addition to its use in factories, welding can also be performed in a variety of environments, such as in the field, underwater and in space. Welding, wherever it occurs, can pose a hazard to the operator, so proper precautions must be taken when welding.
焊枪焊接结构件时，经常需要使用保护气将焊接位置与空气隔绝，以保证焊接质量。焊枪上设置有喷嘴，喷嘴通过管路与装有保护气的气罐连通，管路上设置电磁阀控制管路的连通或断开，气罐内的保护气压力大于大气压。电磁阀开启后，气罐内的保护气经管路流向喷嘴，从喷嘴喷出。焊接过程可以分为三个阶段：引弧阶段、主焊接阶段和回烧阶段，保护气体的状态直接影响到焊接电弧的状态，保护气体的状态包括保护气体的流量、压力、成分等；其中，气体流量根据焊接方法、焊接工艺规范、焊接材料等内容设定，保证焊接无气孔以及焊接过程的稳定。用于通保护气的管路通常称为气管，作为较为重要的零部件，必须拥有耐高温的特性，以适应焊接的高温环境，然而目前的耐高温设备(气管)依然存在以下不足：When the welding torch welds structural parts, it is often necessary to use shielding gas to isolate the welding position from the air to ensure the welding quality. The welding torch is provided with a nozzle, and the nozzle communicates with the gas tank containing the shielding gas through the pipeline, and a solenoid valve is set on the pipeline to control the connection or disconnection of the pipeline, and the pressure of the shielding gas in the gas tank is greater than atmospheric pressure. After the solenoid valve is opened, the protective gas in the gas tank flows to the nozzle through the pipeline, and is sprayed out from the nozzle. The welding process can be divided into three stages: the arc ignition stage, the main welding stage and the burn-back stage. The state of the shielding gas directly affects the state of the welding arc, and the state of the shielding gas includes the flow, pressure, composition, etc. of the shielding gas; among them, The gas flow rate is set according to the welding method, welding process specifications, welding materials, etc., to ensure that the welding has no pores and the stability of the welding process. The pipeline used to pass the shielding gas is usually called a gas pipe. As a relatively important component, it must have high temperature resistance to adapt to the high temperature environment of welding. However, the current high temperature resistant equipment (gas pipe) still has the following shortcomings:
首先，现有的气管在与供气机构进行对接时，通常使用螺丝实现气管端部与供气结构的固连，但该连接方式会存在连接位置的气密性差的问题，使得保护气通过连接位置时，出现漏气的问题；First of all, when the existing trachea is docked with the gas supply mechanism, screws are usually used to secure the end of the trachea to the gas supply structure. position, there is a problem of air leakage;
其次，现有的气管一般分为软管和硬管两种，软管便于焊枪操作，但连接位置容易出现松动问题，硬管则虽便于安装，接口位置稳定，但接口位置容易因焊枪焊接操作而拉扯断裂、崩坏。Secondly, the existing air pipes are generally divided into two types: flexible pipes and hard pipes. The flexible pipes are easy to operate with the welding torch, but the connection position is prone to loosening. And pulling, breaking, and collapsing.
因此，急需对此缺点进行改进，本发明则是针对现有的结构及不足予以研究改良，提供有一种焊接用耐高温设备。Therefore, it is urgent to improve this shortcoming. The present invention studies and improves the existing structure and deficiencies, and provides a kind of high temperature resistant equipment for welding.

Since the gas pipe assembly is composed of PTFE hose, PTFE hard tube 1 and PTFE hard tube 2, the design of PTFE hose facilitates the flexible use of the welding torch, while the PTFE hard tube Pipe 1 and PTFE hard pipe 2 facilitate the connection of the air pipe assembly with the gas supply mechanism and the welding torch, and the connection positions of the soft and hard pipes are all provided with a sealed butt joint assembly, and the left connecting ring and the right connecting ring are limited by the connecting bolt.

During the welding process, since the pressure balancer is connected to the gas storage tank through the first connecting pipe, and is connected to the through pipe through the second connecting pipe and the pressure balance pipe, when the pressure balancer detects that the pressure is abnormal , Realize the pressure balance operation through the pressure balance tube in time.
