Gaseous tension in the pressure vessel 1 requires between 0.25-0.3Mpa, pressure vessel 1 top is provided with pressure and regulates interface 23 and pressure switch interface 24, and the pressure in the pressure vessel 1 is regulated by the blowdown valve 20 that is installed on the pressure adjusting interface 23 and jointly realized with the pressure switch 21 that is installed in pressure switch interface 24.The design of pressure of pressure switch 21 is between 0.25-0.3Mpa, and when pressure was lower than 0.25Mpa, pressure switch 21 negative saltus steps drove blowdown valve 20 and close the exhaust passage, stop outward exhaust; When pressure was higher than 0.3Mpa, pressure switch 21 positive transitions drove blowdown valve 20 and open the exhaust passage, outward exhaust.Spray gun 3 is connected with pressure vessel 1 by the spray gun interface, from the pressurized air of air feed tank 10 inlet end 29 by spray gun 3 through nozzle 25 to pressure vessel 1 interior gas jet, and form fine and closely woven foam, and it is 0.40Mpa that spray gun 3 normal operating conditions pressure require, the unlatching gaseous tension of spray gun 3 is 0.3Mpa, when pressure is higher than 0.3Mpa, spray gun 3 is opened, to pressure vessel 1 interior gas jet, when pressure is lower than 0.3Mpa, spray gun 3 autoshutdowns stop to pressure vessel 1 interior gas jet.The inlet end 29 of spray gun 3 adopts a circulation to be interrupted the air feed control system, and then air feed 10s disconnects air feed 2s, circulates 100 times, stops 100 times so that spray gun starts repeatedly, and system stops automatically, judges according to the operating position of experimental result to spray gun.The experiment pick-up unit of spray gun special use once can be checked 10 spray guns 3.Pressure vessel 1 interior gaseous tension is between 0.25-0.3Mpa, and pressure is regulated the pressure signal input control cabinet that obtains by pressure switch 21, drives blowdown valve 20 by switch board and realizes control.The design of pressure of pressure switch 21 is between 0.25-0.3Mpa, and when pressure was lower than 0.25Mpa, pressure switch was born saltus step, drives blowdown valve 20 by switch board and closes the exhaust passage, stops outward exhaust; When pressure was higher than 0.3Mpa, pressure switch 21 positive transitions drove blowdown valve 20 and open the exhaust passage, outward exhaust.
The explanation of spray gun experimental check device implementation procedure:
1, this experimental check apparatus main body is a pressure vessel, and by water filling port water filling in the container, water filling highly checks water level by the water level observation window mouth.
2, this verifying attachment water level requirement will produce certain pressure to the spray gun interface.
3, the water level observation window mouth adopts the transparent PVC material to make, and built-in ball float can see that when water level raises ball float rises.
4, this experimental provision water level requires to reach the height of water level observation window mouth 1/2nd.
5, gas in container pressure requires between 0.25-0.3Mpa, and pressure is regulated by the blowdown valve of pressure adjusting interface and the pressure switch of pressure switch interface and jointly realized.
6, the pressure switch interface connects a pressure switch, and the design of pressure of pressure switch is between 0.25-0.3Mpa, and when pressure was lower than 0.25Mpa, pressure switch was born saltus step, drives blowdown valve and closes the exhaust passage, stops outward exhaust; When pressure was higher than 0.3Mpa, the pressure switch positive transition drove blowdown valve and opens the exhaust passage, outward exhaust.
7, spray gun is connected with pressure vessel by the spray gun interface, and the inlet end that pressurized air passes through spray gun is through nozzle gas jet in the container, and forms fine and closely woven foam.
8, the unlatching gaseous tension of spray gun is 0.3Mpa, and when pressure was higher than 0.3Mpa, spray gun was opened, gas jet in the container, spray gun normal operating conditions pressure requires to be 0.40Mpa, and spray gun autoshutdown when pressure is lower than 0.3Mpa stops gas jet in the container.
9, for reaching the purpose of check spray gun quality, the inlet end of spray gun adopts a circulation to be interrupted the air feed control system, and then air feed 10s disconnects air feed 2s, circulates 100 times, so that spray gun repeatedly starts and stops 100 times, system stops automatically.
10, judge according to the operating position of experimental result to spray gun.
11, this experimental provision once can be checked at most 10 spray guns.
The above only is the preferred embodiments of the present invention; be not so limit claim of the present invention; every equivalent structure transformation that utilizes instructions of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
