Fig. 1 is a schematic overall structure diagram of a water test device for a fire fighting tail end in an embodiment of the invention, fig. 2 is a sectional view of a three-way valve body in the embodiment of the invention, and fig. 3 is a top view of the three-way valve body in the embodiment of the invention.
As shown in fig. 1, the water test device for a fire fighting terminal in this embodiment includes: the three-way electromagnetic valve comprises a three-way valve body 1, a first electromagnetic valve 2, a second electromagnetic valve 3, a third electromagnetic valve 4, a first pressure sensor 5, a second pressure sensor 6, a water return tank 7, a pressure pump 8 and a controller (not shown).
Wherein, the three-way valve body 1 is provided with a first mounting end 101, a second mounting end 102 and a third mounting end 103 which are communicated with each other.
The first mounting end 101 is provided with a first mounting boss 1011 and a first gauge hole 1012. The first mounting table 1011 is provided with a first mounting hole in which the first solenoid valve 2 is installed. The first pressure sensor 5 is disposed within the first gauge hole 1012.
It should be noted that the first mounting table 1011 is actually a boss for mounting and fixing the solenoid valve, such as the mounting position of the valve flap and the valve stem of the solenoid valve shown in fig. 3. Meanwhile, as the prior art, the electromagnetic valve mainly includes valve flaps (a first valve flap 202, a second valve flap 302, and a third valve flap 402), valve rods (a first valve rod 201, a second valve rod 301, and a third valve rod 401), and an electromagnetic actuator as shown in fig. 2, and the installation schematic diagram thereof is not described again. The first solenoid valve 2 is used to control the conduction of the first mounting end 101 of the three-way valve body 1. The first pressure sensor 5 functions to detect the pressure of the first mounting end 101.
The second mounting end 102 is provided with a second mounting platform, the second mounting platform is provided with a second mounting hole, and the second electromagnetic valve 3 is installed in the second mounting hole. The second solenoid valve 3 is used for controlling the conduction of the second mounting end 102.
The third mounting end 103 is provided with a third mounting plate 1031 and a second meter hole 1032, the third mounting plate 1031 is provided with a third mounting hole, the third solenoid valve 4 is installed in the third mounting hole, and the second pressure sensor 6 is provided in the second meter hole 1032.

The water return tank 7 is provided with a water inlet and a water outlet, as shown in fig. 1, the water inlet is communicated with the second mounting end 102, and the water outlet is communicated with the third mounting end 103. The pressure pump 8 is arranged at a water outlet in the water return tank 7.
The purpose of the return tank 7 is to temporarily store the test outflow water. The function of the pressure pump 8 is to pressurize the water in the return tank 7 so that it can be returned through the test line.
Although the water test device has the characteristic of using a small amount of test water, when the fire-fighting tail end does not have the allowable condition for pressing the test water back, the water test device only allows the test to be performed by taking the amount of water contained in the water return tank as a limit in each test, and once the water in the water return tank is full, the water test device should be detached first, and the water is discharged through the discharge pipeline and then installed and tested. Of course, in the case of a test where the amount of water flowing out is very small and the fire fighting tip is allowed to be pressed back (especially when the test water test device is used in a laboratory), the test water can be pressed back without having to say that the test water test device is detached.
The controller is respectively electrically connected with the first electromagnetic valve 2, the second electromagnetic valve 3, the third electromagnetic valve 4 and the booster pump 8. The controller is used for electrically controlling the first electromagnetic valve 2, the second electromagnetic valve 3, the third electromagnetic valve 4 and the booster pump 8. Specifically, one possible test procedure and role of the controller in the water test procedure is as follows:
the water testing device is connected to a fire-fighting terminal interface to be tested through the first mounting end 101, before testing begins, the controller firstly closes the third electromagnetic valve 4, opens the second electromagnetic valve 3 and the first electromagnetic valve 2, and water flow of water testing flows into the water return tank 7 through the first mounting end 101 and the second mounting end 102. In the process, the first pressure sensor 5 tests the pressure and transmits the test result to the controller, and the controller leads the test result out. The above is a test process.
And after one or more test processes are finished, carrying out a water return process. Since the process of removing the device and then testing is very simple in the case of fire fighting tips that do not allow for a push back, only the case where the fire fighting tip allows for a direct push back of the test water is now considered:
the controller closes the second electromagnetic valve 3, simultaneously opens the first electromagnetic valve 2 and the third electromagnetic valve 4, opens the pressure pump 8, and adjusts the power of the pressure pump 8 according to the test result, so that the pressure measured by the second pressure sensor 6 of the third mounting end 103 is higher than the pressure measured by the first pressure sensor, and the purpose that the water in the water return tank 7 is pressed back through the first mounting end 101 is achieved.
It should be noted that one or more test procedures are performed, depending on the volume of the return tank 7.
Through the above, the water test device for the fire fighting terminal can realize the test and the water return process through the three-way valve body 1, the water return tank 7 and the pressure pump 8, the test process does not need to carry out complex installation and debugging work, parts are not easy to lose, the discharge of water in the whole process is small, the pollution is small, the device can be applied to sites with unsmooth drainage, the drainage burden is reduced, and meanwhile, the test uses less water and the test efficiency is high.
