[0002] With the rapid development of social economy, the particularity of construction and enterprise production has led to an increase in the potential for leakage of hazardous chemicals and radioactive substances, as well as combustion, explosion, and collapse, and the probability of accidents has also increased accordingly. Once a disaster occurs, firefighters face hazardous environments such as high temperature, darkness, toxicity, and thick smoke. If they rush into the scene without the corresponding equipment, they will not only fail to complete the task, but also increase casualties. Firefighting robots are a type of special robots that play an increasingly important role in firefighting and emergency rescue. Firefighting robots can reach places that humans cannot reach to extinguish fires.
[0003] At present, when fire-fighting robots are working, due to the long fire-fighting path, switching facilities are set up in the middle section to connect with the delivery pipeline for delivering high-pressure water flow. Most of the existing switching facilities are connected through valves, and the ball valves on the fire-fighting robots are mostly two-way conductive structures. When a large negative pressure is generated and the water flows back, the pressurizing equipment is easily damaged. Utility Model Content
