Description
技术领域technical field
本发明涉及流体输送用不锈钢管道连接领域，尤其适用于饮用水、自来水、热水等供水用不锈钢管路系统连接，也适合于燃气、燃油等领域油气领域的管路系统连接。The invention relates to the field of stainless steel pipeline connection for fluid transportation, and is especially suitable for the connection of stainless steel pipeline systems for water supply such as drinking water, tap water and hot water, and is also suitable for the connection of pipeline systems in the oil and gas fields of gas, fuel and other fields.
背景技术Background technique
在饮用水、自来水、热水、燃气等供水、供气领域，薄壁不锈钢管由于其耐蚀性强、使用寿命长、可靠性高等特点，逐步替代碳钢管及塑料管，应用越来越广泛。此类薄壁不锈钢管由于其工作压力小，成本因素等原因，壁厚一般控制在2mm以下。In the field of drinking water, tap water, hot water, gas and other water supply and gas supply, thin-walled stainless steel pipes are gradually replacing carbon steel pipes and plastic pipes due to their strong corrosion resistance, long service life and high reliability, and are more and more widely used. . Due to its low working pressure and cost factors, the wall thickness of such thin-walled stainless steel pipes is generally controlled below 2mm.
由于壁厚较薄，此类不锈钢管不能像碳钢管一样进行管端套丝而使用螺纹式接头的连接。所以现有的薄壁不锈钢管连接方式常采用焊接式接头连接或压缩式连接等连接方法，而不是基于螺纹式连接方法。GB/T29038-2012薄壁不锈钢管道技术规范详细列出了卡压式连接、环压式连接、可曲挠螺纹式连接、压缩式连接、卡套式连接、对接氩弧焊连接、承插氩弧焊连接、扩环式连接、沟槽式连接、法兰连接等多种管道连接技术。上述连接方式都是基于焊接式接头连接或压缩式连接方法，存在各自的缺点，例如现场安装设备笨重，接头不能拆装，结构复杂，成本高，可靠性不高等。Due to the thin wall thickness, this type of stainless steel pipe cannot be threaded at the end of the pipe like carbon steel pipes and connected with threaded joints. Therefore, the existing connection methods of thin-walled stainless steel pipes often use connection methods such as welded joint connections or compression connections, rather than threaded connection methods. GB/T29038-2012 technical specification for thin-walled stainless steel pipes lists in detail compression type connection, ring pressure type connection, flexible thread type connection, compression type connection, ferrule type connection, butt argon arc welding connection, socket argon connection Arc welding connection, ring expansion connection, groove connection, flange connection and other pipeline connection technologies. The above-mentioned connection methods are all based on welded joint connection or compression connection method, which have their own shortcomings, such as bulky on-site installation equipment, non-detachable joints, complex structure, high cost, and low reliability.
采用螺纹式连接的连接方式仍然是管路最方便、最可靠的连接方式，但由于薄壁不锈钢管不能套标准丝，将薄壁不锈钢管管端制成波纹的方式实现螺旋式连接为本发明所提供的一种可行性方案。查询现有国内外技术及相关专利，均未有采用与本技术相同或相似的波纹螺旋式的连接接头及装置。同时采用本发明提供的技术方案及系统，不仅可实现直管与直管，同时也方便直管与波纹管、波纹管与波纹管连接，查询相关技术及专利，均未发现有类似技术能实现同时适用于直管和波纹管的连接接头及装置。The connection method using threaded connection is still the most convenient and reliable connection method for pipelines, but because thin-walled stainless steel pipes cannot be covered with standard wires, the method of corrugating the ends of thin-walled stainless steel pipes to realize spiral connection is the invention. A feasible solution is provided. Check the existing domestic and foreign technologies and related patents, and there is no corrugated spiral connection joint and device that is the same or similar to this technology. At the same time, the technical scheme and system provided by the present invention can not only realize straight pipes and straight pipes, but also facilitate the connection of straight pipes and corrugated pipes, and corrugated pipes and corrugated pipes. Inquiring related technologies and patents, no similar technology can be found. It is also suitable for connecting joints and devices of straight pipes and corrugated pipes.
