Onsite fire hose detection device quick in water filling and pressure stabilizing

Abstract

The invention discloses an onsite fire hose detection device quick in water filling and pressure stabilizing. The onsite fire hose detection device comprises a motor, a booster pump and a detector, the detector comprises a shell, a detection end A, a detection end B, a digital display pressure controller, a water inlet end A, a water inlet end B and a water outlet end, the detection end A positioned on the shell is used for detecting a burst pressure of a fire hose, and the detection end B is used for detecting integral performances of the fire hose and connectors. The shell internally comprises a chamber A and a chamber B, the water inlet end B and the water outlet end connected with a water inlet of the booster pump are communicated with the chamber A, the detection end A and the water inlet end A connected with a water outlet of the booster pump are communicated with the chamber B, and a check valve is arranged between the chamber A and the chamber B. When the water pressure in the chamber B is larger than that in the chamber A, the check valve is turned off, and the digital display pressure controller is connected to the chamber B to control starting of the motor through a contactor. The onsite fire hose detection device is convenient and quick in detection and accurate in detection result and capable of quickly filling the fire hose with water within 1min and has a function of pressure maintaining.

Description

technical field [0001] The invention relates to an on-site detection device for a fire-fighting hose, in particular to an on-site detection device for a fire-fighting hose capable of rapid water filling and voltage stabilization, and belongs to the field of fire safety detection devices. Background technique: [0002] The existing fire hose on-site detection device has the following defects during use: 1) It cannot quickly fill the fire hose with water. According to the "Fire Hose" GB6246-2011 testing standard, it is required to fill the 1.2m fire hose within 1 minute. The water hose, and the previous detection device has only one water inlet, that is, the water outlet of the booster pump. The flow and velocity of the booster pump determine the water filling speed of the fire hose, so most of them fail to meet the detection standards In addition, the water inlet of the previous device was a tap water pipe, and the fire hydrant was not used to enter the water, so the flow rat...
