Abstract
A pollution-free liquid balancing 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 sealing bag (1) is filled with the liquid balancing matter (4) inside, and plastically sealed under high temperature at both ends. The diameters of the front cover (2) and the rear cover (3) are matched with the inner diameter of a launch barrel (5), and the sealing bag (1) is provided between the front cover (2) and the rear cover (3). In an ordinary transportation state, the liquid balancing matter (4) is well sealed in the sealing bag (1), and a missile is launched forward by the 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. The forward and backward impulses are similar or equal, thereby reducing or eliminating the impulse to the launch barrel (5) during launch. The device has a simple structure and uses the pollution-free liquid balancing matter (4), thus there is no pollution …
