In order to facilitate understanding of those skilled in the art, the present invention will be further described below with reference to the embodiments and the accompanying drawings. The contents mentioned in the embodiments do not imply any limitation of the present invention. The present invention will be described in detail below with reference to the drawings.

As in 1 As shown, a saturated air pressure vessel provided by the present invention comprises an air supply pressure vessel 1 , a water supply pressure vessel 2 and a carrier 4th on. The water supply pressure vessel 2 is on the upper side of the carrier 4th arranged, and the water supply pressure vessel 2 is provided with a water supply hole in the bottom, and the water supply pressure vessel 1 is near the water supply pressure vessel 2 in a position deeper than the bottom of the water supply pressure vessel 2 is provided with a water supply hole, and the water supply hole and the water connection hole are through a water supply pipe 3 connected with each other. By the principle of the connector to ensure that the water supply pressure vessel 1 is sufficient; in that the supply pressure vessel 1 and the water supply pressure vessel 2 are always connected to ensure that the temperature of the water in the supply pressure vessel 1 is kept within a certain range; when saturated air When the pressure vessel is operating normally, the water level in the air supply pressure vessel rises 1 on and compresses the internal air to create a static pressure layer, and the pressure of the static pressure layer is kept constant by the action of water pressure, thereby ensuring the constant outlet pressure; by controlling the height of the holder 4th , the height of the water level in the water supply pressure vessel 2 and the caliber of the water supply pipe 5 the size of the air pressure in the static pressure layer can be controlled.

Further is the water supply pressure vessel 1 with a water level upper limit line 5 provided, and the bottom of the water supply pressure vessel 2 is aligned with the upper limit line of the water level 5 . The water level upper limit line 5 can be adjusted according to the required air pressure to exceed the air supply pressure. The positions of the water level line and the water level upper limit line 5 of the container 1 are used to determine the real-time pressure of the static pressure layer, which means that the gas supply speed to the gas supply pressure vessel can be adjusted at any time 1 is cheap.

Furthermore, a first overflow hole is on one side of the upper limit line 5 the water level in the vicinity of the water supply pressure vessel 2 is provided, and a second overflow hole is correspondingly on one side of the water supply pressure vessel 2 near the air supply pressure vessel 1 intended. The first overflow hole goes through the overflow pipe 6th is connected to the second overflow hole. Most preferably the second overflow hole is above the water surface of the water supply pressure vessel 2 intended. If the air pressure in the air supply pressure vessel 1 decreases and the water level the upper limit of the water level 5 it can be increased by The air inlet into the supply pressure tank 1 allows leaving the water that is the upper limit of the water level 5 exceeds, through the overflow pipe 6th to the feed pressure tank 2 under the action of air pressure, so the amount of water between the supply pressure tank 1 and the supply pressure tank 2 maintains a dynamic equilibrium; maintaining a constant space at the top of the air supply pressure vessel 1 is beneficial for separating the filtered air from water vapor and ensuring the purity of the discharged saturated air.

There is also an air supply pipe 7th to the bottom of the air supply pressure vessel 1 connected, one end of the air supply tube 7th is to the air supply pressure vessel 1 and the other end is connected to an external air supply device; the air supply pipe 7th is connected to the air supply pressure vessel. One end of 1 is on an annular ring 8th connected. The surface of the annular ring 8th is provided with evenly spaced overflow holes that can allow air to flow from each of the overflow holes in the form of small bubbles into the air pressure vessel 1 enter so that the air is completely filtered and the heat is more even.

There is also a transparent liquid viewing tube 9 on the outer side wall of the air supply pressure vessel 1 provided what is convenient for users to the height of the water level in the air pressure tank 1 to be able to observe at any time, whereby you can derive the amount of air in the static pressure layer, which is favorable for adjusting the entered air. The speed and the speed of the discharged saturated air ensure the constant pressure of the static pressure layer.

There is also a temperature sensor 10 for measuring the temperature of the static pressure layer on the inside of the upper part of the saturated pressure vessel 1 provided, and the heating condition of the air supply pressure vessel 1 for water can be adjusted by the measured temperature to provide a satisfactory air temperature; a safety valve 11 is on the outside of the top of the saturated pressure vessel 1 intended. A pressure gauge is also preferred 16 for real-time feedback of the pressure of the static pressure layer on the outside of the upper part of the supplied pressure vessel 1 intended. If the air pressure is too high, the safety valve can 11 be opened to deflate the air so that the air pressure can be reduced to a safe level to prevent the gas supply pressure keg 1 explodes due to excessive air pressure.

Further, the inner side wall of the water supply pressure vessel is provided with an upper water level device 12th and a lower water level device 13th Mistake; the outer side wall of the bottom of the water supply pressure barrel 1 is also available with an automatic water supply pipe 14th provided when the water level in the water supply pressure barrel 2 is not higher than when the water level device 13th is started, the water level device sends 13th a signal. After receiving the signal, the automatic water supply pipe opens 14th automatically and gives water to the water supply pressure tank 2 away. Similarly, if the water level is in the water supply pressure vessel 2 If the device is not lower than the upper water level 12th is activated, the upper water level device sends 12th a signal. Upon receipt of the signal from the upper water level device 12th holds the automatic water supply pipe 14th the water supply to the water supply pressure vessel 2 , thereby ensuring that the amount of water in the water supply pressure vessel 2 is always kept at a value. Also, by avoiding the pressure drop of the static printing layer due to insufficient water, the automatic water supply can effectively reduce manual operations and save costs. The water supply pressure vessel is preferred 2 also with a manual water supply valve 15th Mistake. When an artificial water supply is needed or the automatic water supply pipe 14th if it fails, water can enter the water supply pressure vessel 2 through the manual water supply valve 15th manually added what the water supply pressure vessel 2 improved. Work stability and reliability.

In 2 There is shown a saline spray tester of the present invention, the air supply device of which is a saturated air pressure vessel of the embodiment 1 is, the saturated air pressure vessel is different from the embodiment 1 in that: a spray pressure regulating valve 17th between the air supply pipe 7th and the external air supply device is provided that can adjust the state of the discharged air to adjust the pressure of the salt water spray so that the salt water spray test is more controllable.
