Description
技术领域 technical field
本实用新型涉及一种输气管路连接部件，特别是涉及一种输气管路连接用三通，密封性能好，丝扣连处不易发生断裂，使用寿命长。 The utility model relates to a connection part of a gas transmission pipeline, in particular to a tee for connection of a gas transmission pipeline, which has good sealing performance, is not easy to be broken at the joint of a screw thread, and has a long service life.
背景技术 Background technique
燃气化建设和发展，是提高城市人民生活水平和素质的重要措施之一。燃气输送离不开管路系统。而管路的连接又离不开连接件，如三通、弯头、阀等。其中目前使用的三通，三个连接口的内螺纹段短，造成与之连接端的镀锌管的外螺纹外露，极易受到腐蚀，导致管壁减薄，机械强度减弱，丝扣连接处易发生断裂，减少镀锌管的使用寿命同时易出现燃气泄漏事故。 The construction and development of gasification is one of the important measures to improve the living standard and quality of urban people. Gas transmission is inseparable from the pipeline system. The connection of pipelines is inseparable from connectors, such as tees, elbows, valves, etc. Among them, the three links currently used have short internal thread segments, which cause the external thread of the galvanized pipe at the connected end to be exposed, which is extremely susceptible to corrosion, resulting in thinning of the pipe wall, weakening of the mechanical strength, and easy screw connection. Breakage occurs, reducing the service life of the galvanized pipe and prone to gas leakage accidents.
实用新型内容 Utility model content
本实用新型的目的，是针对现有三通存在的上述不足而提供一种输气管路连接用三通。本实用新型能保护连接处丝扣不暴露在外，提供了耐腐蚀能力和使用寿命，且提高了燃气管路的使用安全性能。 The purpose of this utility model is to provide a kind of tee for gas pipeline connection aiming at the above-mentioned shortcomings existing in the existing tee. The utility model can protect the screw thread at the connection from being exposed, provides corrosion resistance and service life, and improves the use safety performance of the gas pipeline.
采用的技术方案是： The technical solutions adopted are:
一种输气管路连接用三通，包括三通，所述三通为已知市售三通，其特征在于： A kind of tee for gas pipeline connection, comprising a tee, said tee is a known commercially available tee, characterized in that:
三通的第一接口处外延有第一加长接口，第一加长接口与第一接口为一次成型的整体结构，且第一加长接口的内螺纹与第一接口的内螺纹匹配连接。 The extension of the first joint of the tee has a first extension joint, the first extension joint and the first joint are integral structures formed at one time, and the inner thread of the first extension joint is mated and connected with the inner thread of the first joint.
三通的第二接口处外延有第二加长接口，第二加长接口与第二接口为一次成型的整体结构，且第二接口的内螺纹与第二接口的内螺纹匹配连接。 The second extension of the tee is extended to the second interface. The second extension and the second interface are integral structures formed at one time, and the inner thread of the second interface is mated with the inner thread of the second interface.
三通的第三接口处外延有第三加长接口，第三加长接口与第三接口为一次成型的整体结构，且第三加长接口的内螺纹与第三接口的内螺纹匹配连接。 The third joint of the tee is extended with a third extended joint, the third extended joint and the third joint are integrally formed at one time, and the inner thread of the third extended joint is mated with the inner thread of the third joint.
本实用新型的优点： Advantage of the utility model:
本实用新型由三个接口处分别有一体化的加长接口，能有效保护连接的镀锌管处丝扣不暴在外，提高了耐腐蚀力，提高了使用寿命。另外，提高了管道的安全性能，原来的三通接口短，连接的镀锌管外露的螺纹段因极易受到腐蚀而导致管壁减薄，机械性能减弱，密封效果差，易出现燃气泄漏，造成事故。本实用新型密封性能好，安全性能高，且安装方便。 The utility model has integrated elongated joints at the three joints respectively, which can effectively protect the threads of the connected galvanized pipes from being exposed, improve the corrosion resistance and prolong the service life. In addition, the safety performance of the pipeline is improved. The original three-way joint is short, and the exposed threaded section of the connected galvanized pipe is extremely susceptible to corrosion, which leads to thinning of the pipe wall, weakened mechanical properties, poor sealing effect, and prone to gas leakage. cause an accident. The utility model has good sealing performance, high safety performance and convenient installation.
