Patent ID: 8707847

Claim:
A pollution-free liquid balancing device, characterized in that the device comprises: a sealing bag ( 1 ), a front cover ( 2 ), a rear cover ( 3 ) and liquid balancing matter ( 4 ), wherein the sealing bag ( 1 ), the front cover ( 2 ) and the rear cover ( 3 ) are all plastic material, the liquid balancing matter ( 4 ) comprises: water, anti-corrosion additives, antifreeze agents and inorganic salts; the mass of the liquid balancing matter ( 4 ) is 1˜1.5 times that of launch matter, the anti-corrosion additives and the antifreeze agents are liquid or soluble substances and do not react chemically with the sealing bag, the inorganic salts are also soluble substances and do not react chemically with the sealing bag, and the solubility is stable during temperature changes; the sealing bag ( 1 ) is filled with the liquid balancing matter ( 4 ) and plastically sealed under high temperature at both ends, diameters of the front cover ( 2 ) and the rear cover ( 3 ) are matched with an inner diameter of a launch barrel ( 5 ), and the sealing bag ( 1 ) is provided between the front cover ( 2 ) and the rear cover ( 3 ); the anti-corrosion additives are used to adjust the PH of the liquid balancing matter, the anti-freeze agents are used to reduce the freezing point of the liquid balancing matter, the inorganic salts are used to increase the density of the liquid balancing matter, in an ordinary transportation state, the liquid balancing matter ( 4 ) is well sealed in the sealing bag ( 1 ), when a missile is launched forward by propulsion of powder during launch, the sealing bag ( 1 ), the front cover ( 2 ) and the rear cover ( 3 ) crack instantaneously, and the liquid balancing matter ( 4 ) is ejected backward outside the barrel at high speed, forward and backward impulses are similar or equal, thereby reducing or eliminating the impulse to the launch barrel ( 5 ).
