A sealed liquid storage tank with an elastic liner compensating device

Abstract

The invention relates to a sealed liquid storage tank with an elastic inner container compensation device. The sealed liquid storage tank with the elastic inner container compensation device comprises a sealed liquid storage tank body. The top of the sealed liquid storage tank body is provided with a liquid inlet and a liquid inlet electromagnetic valve. The bottom of the sealed liquid storage tank body is provided with a liquid outlet and a liquid outlet electromagnetic valve. An elastic inner container is arranged in the sealed liquid storage tank body. A blow-down pipe, an airflow balance pipe and an electric contact pressure gauge are further arranged on the top of the sealed liquid storage tank body. The head end of the airflow balance pipe is connected with an elastic inner container vent of the elastic inner container, the tail end of the airflow balance pipe is connected with an air compressor through a three-way straight pipe electromagnetic valve, and the airflow balance pipe is further provided with a three-way bypass electromagnetic valve. The sealed liquid storage tank body is further provided with an electric contact liquid level meter. The sealed liquid storage tank further comprises a control module used for automatically controlling the electromagnetic valves. The invention further relates to a using method of the sealed liquid storage tank with the elastic inner container compensation device. Liquid in the sealed liquid storage tank body is kept isolated from outside air and prevented from being affected with damp, oxidized and polluted, and the effect that the liquid can be stored safely and reliably for a long time is guaranteed.

Description

technical field [0001] The invention relates to a sealed liquid storage tank with an elastic liner compensating device and a usage method thereof. Background technique [0002] When some liquids are in contact with air, moisture or other impurities, they are prone to oxidation reactions and other chemical reactions, or they will deteriorate and deteriorate due to moisture and gas dissolved in the liquids, so they cannot be used. These sensitive liquids need to be stored in airtight containers and stored in airtight containers. The intrusion of oxygen, moisture or other impurities can be avoided during the work of entering and exiting the liquid, but some of the dynamic sealing methods of the traditional liquid storage container adopt nitrogen balance sealing, or adopt vacuum sealing and other methods to achieve, and use nitrogen balance dynamic sealing. The method is not suitable for some liquids that are harmful to nitrogen, especially for ultra-high voltage and ultra-high ...

[0002] When some liquids are in contact with air, moisture or other impurities, they are prone to oxidation reactions and other chemical reactions, or they will deteriorate and deteriorate due to moisture and gas dissolved in the liquids, so they cannot be used. These sensitive liquids need to be stored in airtight containers and stored in airtight containers. The intrusion of oxygen, moisture or other impurities can be avoided during the work of entering and exiting the liquid, but some of the dynamic sealing methods of the traditional liquid storage container adopt nitrogen balance sealing, or adopt vacuum sealing and other methods to achieve, and use nitrogen balance dynamic sealing. The method is not suitable for some liquids that are harmful to nitrogen, especially for ultra-high voltage and ultra-high voltage transformer oils used in the power industry, which have strict requirements on the gas content in the oil, and nitrogen is easily soluble in power oil. Thereby can not be used; And the method for vacuum sealing, its manufacturing, use and maintenance, overhaul cost are high, and difficult to operate, especially when the negative pressure system seal is damaged, the container is very easy to inhale outside air, moisture and damage stored in the container. liquid
