Description

TECHNICAL FIELD

[0001] The utility model relates to fire hose equipment technical field, concretely is a kind of tensile leak detection device for fire hose production. BACKGROUND

[0002] Fire hose is used to transport high-pressure water or foam and other fire-retardant liquid hose. The traditional fire hose is lined with rubber, and the outer surface is wrapped with linen braid. Since the fire pump can provide a large water pressure, the fire hose needs to withstand a large water pressure when in use to ensure that the water column can be sprayed to the specified height. However, if the sidewall of the fire waterway is damaged or leaks, the break will rapidly expand under the action of high pressure, which brings unnecessary danger to the firefighters. Therefore, its sealing property is particularly important. If the fire hose is damaged, the pressure will not be enough when the fire hose is used, so the water cannot be sprayed quickly for fire extinguishing. In the existing technology, the leak detection of the fire hose is generally carried out by water detection of the entire fire hose. The water flows through the entire fire hose, and the water pressure is reduced. If the crack of the damaged part is small, the lower water pressure cannot be obviously sprayed from the crack, causing detection failure.

[0003] To solve the above problems, the present case arises. SUMMARY
