Abstract

The invention discloses a pneumatic control device for the liquid level. The pneumatic control device is used for a battery formation tank and comprises an angular lever and an adjustor body, the angular lever is communicated with the battery formation tank, and the bottom of the battery formation tank is communicated with a water inlet tube. A float ball arranged inside the battery formation tank is connected to one end of the angular lever, and a slide valve is connected to the other end of the angular lever. A first cavity and a second cavity communicated with the atmosphere are formed inside the adjustor body, wherein the second cavity is separated from the first cavity through a first membrane. A third cavity is formed below the second cavity and separated from the second cavity through a corrugated pipe, a fourth cavity is formed below the third cavity, a second membrane is arranged between the third cavity and the fourth cavity communicated with the third cavity through a guide pipe, the fourth cavity is communicated with an air inlet two-way branch pipe, and the two-way branch pipe is communicated with the slide valve. The pneumatic control device for the liquid level can automatically control the liquid level inside the water tank of a battery formation device.

Description

technical field [0001] The invention belongs to the field of liquid level control, and in particular relates to a liquid level pneumatic regulating device for a battery formation tank. Background technique [0002] Due to the high density of the electrolyte when the battery is formed, the thermal reaction of the battery is accelerated, and the acid content is relatively low, which cannot dissipate heat in time, so the internal temperature of the battery is very high. The higher temperature will increase the water loss in the water tank and affect the quality of battery formation. [0003] In the existing technology, water outlets are provided at both ends of the water tank of the battery formation device, and the water tank is connected with the pool through the water outlets. This kind of drainage method requires on-site observation by the operator. When the water level is found to be higher or lower than the size, the water level in the water tank is manually controlled, ...
