An on-site detection device for fire hoses capable of rapid water filling and pressure stabilization

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...

[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 rate was small, and most of them could not meet the requirements of fast water filling; 2) The existing device can only detect the 1.2m fire hose experiment Pressure, working pressure, and burst pressure values, without the quality and performance of the fire hose interface, cannot detect the overall performance of the fire hose and the interface (whether the fire hose leaks under the working pressure, and whether the fire interface is firm and reliable); 3) It is not possible to automatically start or stop pressurizing the hose through the preset pressure value of the fire hose. Usually, when the pressure gauge reaches the expected pressure value, the motor is manually turned off to stop the pressurization of the hose. There is always a certain delay in time, so the pressure is not easy to maintain at the expected value, and the actual value is either high or low. In addition, with the expansion of the fire hose, the pressure in the fire hose is constantly decreasing and cannot be maintained at the expected value.
