Background technology
Fire hose is commonly used in fire fighting device, and during the use of fire hose, due to fire hose
Abrasion either connection between fire hose and connector there is air-tightness gas leakage, so result in the rescue of fire hose
Extinguishing effect is undesirable, while the high pressure water sprayed from fire hose breakage be easy to cause personnel and accidentally injures, and the water leaked is then
Cause water resource waste, thus it is particularly important to the air-leakage test of fire hose after scrubbing every time, so as to damaged fire-fighting
Water band is replaced or repaired, and excludes hidden danger.It is all in the lab that the detection of existing fire hose air-tightness is most of
It carries out, its air-tightness can not be detected at the first time after fire hose is scrubbed and finished, actual operation is low.
The content of the invention
The purpose of this utility model is to provide for a kind of automatic voltage measurement device for detecting fire hose air-tightness, solves
The problem of practical operation of fire hose air-leakage test is low in the prior art.
The utility model is adopted the technical scheme that solve the above-mentioned problems, provides a kind of detection fire hose gas
The automatic voltage measurement device of close property, it is fixed in the live spindle of the motor to connect including rectangular frame, motor, plunger pump, controller
Be connected to initiative driver, be fixedly connected with passive drive on the transmission shaft of plunger pump, initiative driver and passive drive it
Between be sequentially connected by transmission belt, be fixedly connected on the rectangular frame into water connector, water outlet connector, pressure measurement connection
Head is connected between the water inlet connector and the water inlet of plunger pump by the first connecting tube, water outlet connector and plunger pump
Water outlet between be connected by the second connecting tube, first connecting tube be equipped with the first solenoid directional control valve, second connection
Pipe is equipped with the second solenoid directional control valve, and one end of the pressure measurement connector is blind end, and the end of blind end is passed equipped with pressure
Sensor, first solenoid directional control valve, the second solenoid directional control valve, pressure sensor are electrically connected with the controller.
The second connecting tube between the water outlet of the plunger pump and the second solenoid directional control valve is equipped with the 3rd connecting tube, the
Three connecting tubes are equipped with electromagnetic relief valve, and electromagnetic relief valve is electrically connected with the controller.
The beneficial effects of the utility model：The utility model is simple in structure, simple to operate, convenient for being washed in fire hose
Brush is at the first time detected its air-tightness after finishing, and in order to be replaced in time to fire hose, removes a hidden danger, together
Shi Liyong controllers can in detection process by electromagnetic relief valve by pressure venting superfluous in fire hose, prevent fire-fighting
The excessive damage fire hose of pressure in water band causes security incident.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
To make the purpose of this utility model, technical solution and advantageous effect clearer, below in conjunction with the accompanying drawings to this practicality
New embodiment is described in further detail.
As shown in Figure 1, the utility model provides a kind of automatic voltage measurement device for detecting fire hose air-tightness, including square
Shape frame 1, motor 2, plunger pump 3, controller 4 are fixedly connected with initiative driver 5, plunger in the live spindle of the motor 2
Passive drive 6 is fixedly connected on the transmission shaft of pump 3, is passed between initiative driver 5 and passive drive 6 by transmission belt 7
It is dynamic to connect, it is fixedly connected on the rectangular frame 1 into water connector 8, water outlet connector 9, pressure measurement connector 10, the water inlet
It is connected between connector 8 and the water inlet of plunger pump 3 by the first connecting tube 11, the water outlet of water outlet connector 9 and plunger pump 3
It is connected between mouthful by the second connecting tube 12, first connecting tube 11 is equipped with the first solenoid directional control valve 13, the second connection
Pipe 12 is equipped with the second solenoid directional control valve 14, and one end of the pressure measurement connector 10 is blind end, and the end of blind end is equipped with
Pressure sensor 15, first solenoid directional control valve 13, the second solenoid directional control valve 14, pressure sensor 15 are electrically connected with controller 4
It connects.The second connecting tube 12 between the water outlet of the plunger pump 3 and the second solenoid directional control valve 14 is equipped with the 3rd connecting tube 16,
3rd connecting tube 16 is equipped with electromagnetic relief valve 17, and electromagnetic relief valve 17 is electrically connected with controller 4.
In use, one end of external water pipe 18 is connected with water source, the other end and the water inlet connector 8 of external water pipe 18
It is connected, then the both ends of tested fire hose 19 is connected respectively with water outlet connector 9 and pressure measurement connector 10, then
Opening motor 2 drives plunger pump 3 to work, and the first solenoid directional control valve 13 and the second solenoid directional control valve 14 is kept to keep channel status,
