inside the first work box, and the first work box is more difficult at this time It is in communication with the outside, when the pressure that the first work box inner top is subject to is sufficiently large, water does not enter back into the first work box, and steam can also Enter top in the first work box along exhaust pipe, and be filled with air inside the first floating ball, so that the first floating ball floats always In water surface, steam is constantly accumulated inside the first work box, declines water level constantly, so that the first float position declines, when When upper pressure stabilizing mouth is located at outside the first work box, it is connected to again outside external environment and the first work box, thus the first work box Steam inside is expelled to outdoor along lower pressure stabilizing mouth and upper pressure stabilizing mouth, and after the first work box internal pressure reduces, water level rises again, It drives the first floating ball to rise, makes the first work box and extraneous disconnection again, repeat the above process, the steam in water is expelled to room Outside, pipeline strenuous vibration possibility is reduced, use reliability is improved；Air is filled with inside second floating ball and third floating ball, Second connecting rod connects the second floating ball and third floating ball, and a small amount of LNG of coil pipe output end flows into the second work along fluid hole Make inside case, and constantly accumulated inside the second work box, if LNG amount is less, does not touch the second floating ball and third enough When floating ball, LNG, which can voluntarily volatilize, becomes gaseous state NG, when LNG liquid level touches the second floating ball and third floating ball and constantly rises, Due to inside the second floating ball and third floating ball be filled with air, spring force coefficient is larger, reduce lower liquid outlet leakage can Energy property, when spring moves up, lower liquid outlet is opened, so that LNG stream goes out outside the second work box, and due to LNG's Barrier action, gaseous state NG is more difficult to be detached from the second work box along lower liquid outlet, when the second work box LNG liquid level declines, thus second A possibility that floating ball and decline of third floating ball, lower liquid outlet is blocked, repeated the above process, reduces pipeline frostbite by final chock plug, Improve use reliability.
