Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail.
The invention provides the pipeline damping device in a kind of preserving fruit and vegetable utilizing system gas transfer pipeline, described pipeline damping device comprises: water tank 1, air inlet pipe 4 and blast pipe 5; At water tank 1 built with water B1.
Described air inlet pipe 4 one end connects Compressed Gas A1, and its other end is inserted therein water from water tank 1 top, and the air inlet pipe 4 between Compressed Gas A1 and water tank 1 is equipped with gas Controlling solenoid valve 3.
Described blast pipe 5 one end to connect between fruit vegetables storing 12, and its other end is positioned at water tank 1 top of water tank 1 overfall more than 11, and the blast pipe 5 between fruit vegetables storing between 12 and water tank 1 is equipped with check valve 6.
The effluent outfall 10 of band sewage blow-down valve 9 is housed bottom water tank 1.
On water tank 1 lateral wall, interval is provided with the multiple level electrodes showing liquid level in it.
Water tank 1 sidewall more than described level electrode and between water tank 1 top is provided with overfall 11; Water tank 1 sidewall below described level electrode installs water injection pipe 8, water injection pipe 8 is equipped with water injecting electromagnetic valve 7.
Described gas Controlling solenoid valve 3, level electrode and water injecting electromagnetic valve 7 connection control device.
Described level electrode is disposed with from top to bottom along water tank 1 lateral wall vertical direction: upper upper limit level electrode 2-1, upper limit level electrode 2-2, lower limit level electrode 2-3 and lower lower limit level electrode 2-4.
In described water tank 1, water level is best between upper limit level electrode 2-2 and lower limit level electrode 2-3.
The lower end of described air inlet pipe 4 is inserted in lower limit below the level electrode 2-3 in water tank 1.
Described overfall 11 is positioned at the upper limit more than level electrode 2-1.
Described water injection pipe 8 is positioned at below lower limit level electrode 2-3 horizontal plane.
In described water tank 1 air inlet pipe 4 lower end sidewall on be provided with multiple steam vent.
In particular, described level electrode is outsourcing device, is arranged on the lateral wall of water tank 1, is connected by external cable with control device.When level electrode contacts with the water B1 in water tank 1, export an electronegative potential to control device, when level electrode is separated with the water B1 in water tank 1, export a high potential to control device.The signal that control device feeds back according to level electrode, determines the water level conditions in water tank 1.
The multiple steam vent in described air inlet pipe 4 lower end increases the contact area of gas and water, improves humidifying effect.
Gas Controlling solenoid valve 3 connection control device (not shown).Control device is according to the signal of 12 humidity sensor feedback between fruit vegetables storing, and the open/close states of automatic decision gas Controlling solenoid valve 3, controls Compressed Gas A1 and whether enter water tank 1 through air inlet pipe 4.
