Fig. 1 structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
A kind of multistation electronics valve test platform, comprise water tank 1, have test water in described water tank 1, be linked in sequence outside described water tank 1 water pump 2, normally closed solenoid valve 3 and normally open solenoid valve 9, and described water tank 1, water pump 2, normally closed solenoid valve 3 and normally open solenoid valve 9 form a water flow circuits; The control circuit series connection of described normally closed solenoid valve 3 and normally open solenoid valve 9, when no power, normally closed solenoid valve 3 is closed, and normally open solenoid valve 9 is opened, and when being energized, normally closed solenoid valve 3 is opened, and normally open solenoid valve 9 cuts out; Storage pressure pressure tank 4 is provided with between described water pump 2 and normally closed solenoid valve 3; Water flow circuits between described normally open solenoid valve 3 and normally closed solenoid valve 9 is arranged 4 groups of tributaries, and often organize on tributary and be equipped with a manual ball valve 5, described manual ball valve 5 is connected to manual three-way ball valve 6, two outlets of described manual three-way ball valve 6 are set to left intake tunnel and right intake tunnel respectively, and left intake tunnel and right intake tunnel are connected to the left water inlet of electrovalve to be measured and right water inlet respectively; Correspondence is often organized tributary and is all arranged drain outlet, drain outlet mouth is connected with the sewage draining exit of electrovalve to be measured, and each drain outlet is equipped with blowdown pneumatic ball valve switch 7, and each drain outlet is all connected to water tank, and drain outlet is also provided with blowdown electromagnetic flowmeter 11; Correspondence is often organized tributary and is all arranged suction salt passage, inhale salt passage mouth to be connected with the salt-sucking port of electrovalve to be measured, each suction salt passage is equipped with and inhales salt water filling pneumatic ball valve switch 8, each suction salt passage is all connected to the salt box 10 that salt solution is housed, and inhales on salt passage and is also provided with suction salt electromagnetic flowmeter 12.
During work, first water pump 2 is opened, start to suppress storage pressure pressure tank 4, when storing up the pressure in pressure pressure tank 4 and reaching 0.4MPa, after normally closed solenoid valve 3 and normally open solenoid valve 9 control energising by same electric loop, normally closed solenoid valve 3 is opened, and opens wide solenoid valve 9 and closes, current enter in manual ball valve 5, and manually tee ball valve 6 selects left water inlet or right water inlet.
One of them tributary is tested, opens the manual ball valve 5 in lid tributary, close the manual ball valve 5 in other tributaries.Blowdown pneumatic ball valve 7 on this tributary and suction salt water filling pneumatic ball valve 8 are controlled by same electric loop, entirely open after energising.
Test backwash and when expressing state, open left intake tunnel, close right intake tunnel, test water flows out from sewage draining exit after entering electrovalve to be measured, the flow when blowdown electromagnetic flowmeter 11 test obtains backwash state.
When salt state is inhaled in test, the salt solution in salt box is through entering electrovalve to be measured through inhaling salt water filling port 8, and electromagnetic flowmeter 12 test obtains flow when inhaling salt state.In like manner, charging state current flow in salt box 10 by inhaling salt water filling port 8 from electrovalve to be measured, contrary by the flow direction of inhaling salt water filling electromagnetic flowmeter 12 with suction salt state, can record the flow under charging state equally.
After this tributary is completed, closes the blowdown pneumatic ball valve 7 on this tributary and inhale salt water filling pneumatic ball valve 8, opening the respective switch on next tributary, carrying out next group test.After 4 groups are all completed, after normally closed solenoid valve 3 and normally open solenoid valve 9 control power-off by same electric loop, normally closed solenoid valve 3 is closed, and normally open solenoid valve 9 is opened, in the current reflow tank in electrovalve.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
