摘要: Disclosed herein is a floating ball filling-control device for a cryogenic tank with enhanced structural stability. The floating ball filling-control device comprises a liquid feeding pipe (2) with a liquid discharging end disposed in the liquid storage tank (1), the liquid feeding pipe (2) having liquid spraying holes (3) located on the pipe wall at the top of the pipe, and a slide valve (4) arranged on the top end of the liquid feeding pipe, wherein the slide valve is in a sliding fit with the liquid feeding pipe in a vertical direction via a floating ball lever driving mechanism, and forms an open/close mechanism for the liquid spraying holes via a control mechanism.

摘要: Disclosed herein is an energy efficient vertical cryogenic tank, which comprises a tank body with a vacuum insulation interlayer, wherein the tank body comprises a transmission means including an air return pipe and a liquid outlet pipe, and positioning means including supporting legs provided at the bottom of the tank body, and a built-in saturation adjustment mechanism formed by a heat exchanger connected to an let of the air return pipe and a return air dispersing device. By using a saturation adjustment mechanism at the inlet of the air return pipe, the cryogenic storage tank can not only fully leverage the gasification gas produced at the pump, but also achieve the saturation function of the LNG in the tank, with such benefits as reduced energy loss, simplified tank interface settings, improved efficiency of saturation adjustment, and avoided pump cavitation.
