Pipe flow mechanism of gas-liquid two-phase flow guide type fire monitor and manufacturing method of pipe flow mechanism
The invention relates to the technical field of fire fighting equipment, and discloses a gas-liquid two-phase flow guide type fire monitor pipe flow mechanism which comprises a pipe body, the pipe body is of a hollow funnel-shaped structure, a necking-down section used for disturbing gas and liquid is arranged at the upward position of the pipe wall of the pipe body, the necking-down section is of an annular structure, and the section of the necking-down section is of a right trapezoid structure; and the gas-liquid is guided to be gathered at the pipe orifice. Through high hardness and good wear resistance of monoclinic zirconium oxide and cerium oxide, a firm structure is formed, so that the flow guide pipe can effectively resist wear in long-term use, and meanwhile, due to high melting point and low thermal expansion coefficient of magnesium oxide, the flow guide pipe is not easy to deform and crack in a high-temperature environment, so that the flow guide pipe is more durable. The pipe flow mechanism of the fire monitor can better adapt to a fire scene environment, and can effectively relieve thermal stress, so that the pipe flow mechanism of the fire monitor can still keep excellent performance when being continuously used in the fire scene, and the fire extinguishing efficiency is improved.
本申请涉及消防设备技术领域，公开了一种气液两相导流式消防炮的管流机构，包括管体，所述管体为中空的漏斗状结构，在其管壁向上的位置设有用于扰乱气液的缩口段，所述缩口段为环状结构且其截面呈直角梯形结构，用于引导气液汇聚在管口处。通过单斜氧化锆和氧化铈的高硬度和良好的抗磨损特性，形成了坚固的结构，使得导流管在长期使用中能够有效抵抗磨损，同时使用的氧化镁的高熔点和低热膨胀系数，使得导流管在高温环境下不易发生变形和开裂，可以更好的适应消防火场环境使用，同时能够有效缓解热应力，使得消防炮的管流机构在火场持续使用时仍然能够保持出色的性能，提高灭火的效率。
