本发明的工作原理如下: The working principle of the present invention is as follows:

当罐体内的气压小于外界大气压,负压中筒外液面上升,负压中筒内液面下降,且下降到一定位置,罐体外的气体就可以通过负压保护腔体中的液封,进入罐体内部,达到罐体内压强恢复正常的目的,从而保护大型密封式罐体。当罐体内部压强增大,罐体内的气体首先进入负压保护腔体,并通过负压顶板的中心孔进入正压保护腔体。当罐体内压强持续增大,正压中筒外液面上升,正压中筒内液面下降,下降到一定位置时,罐体内的气体便可通过正压保护腔体内的液封,通过正压排气口进入外界大气层,从而达到大型密封式罐体的泄压目的。在正压保护腔体和负压保护腔体一侧分别为正压液位计和负压液位计可以显示加液的液位高度,指导液体添加。 When the air pressure in the tank is lower than the external atmospheric pressure, the liquid level outside the cylinder rises in the negative pressure, and the liquid level in the cylinder falls in the negative pressure, and falls to a certain position, the gas outside the tank can protect the liquid seal in the cavity through the negative pressure, Enter the inside of the tank to achieve the purpose of restoring the pressure inside the tank to normal, thereby protecting the large sealed tank. When the internal pressure of the tank increases, the gas in the tank first enters the negative pressure protection cavity, and then enters the positive pressure protection cavity through the central hole of the negative pressure top plate. When the pressure inside the tank continues to increase, the liquid level outside the cylinder under positive pressure rises, and the liquid level inside the cylinder under positive pressure drops to a certain position, the gas in the tank can pass through the liquid seal in the positive pressure protection cavity, The pressure exhaust port enters the outside atmosphere, so as to achieve the purpose of pressure relief for large sealed tanks. On one side of the positive pressure protection cavity and the negative pressure protection cavity, there are respectively a positive pressure liquid level gauge and a negative pressure liquid level gauge, which can display the liquid level height of the liquid and guide the liquid addition.
