Abstract

The invention discloses a pressure balance device capable of preventing ballooning of a liquid storage tank, the liquid storage tank and a machine tool cooling machine. The pressure balance module isused for the liquid storage tank of the machine tool cooling machine, and comprises an air valve and a floater, wherein a first end of the air valve communicates with the internal of the liquid storage tank, and a second end of the air valve communicates with external air; the air valve is provided with an opening state and a closing state; the floater is arranged in the liquid storage tank, and moves along with the liquid level change in the liquid storage tank; the floater is connected with the air valve through a transmission structure; and the floater is used for controlling opening or closing of the air valve according to the liquid level height in the liquid storage tank. The pressure balance module is provided with the air valve and the floater, and the floater controls opening andclosing of the air valve through the transmission structure, so that air in the liquid storage tank can be timely exhausted to prevent the ballooning deformation of the water tank caused by higher internal pressure of the liquid storage tank during water feeding.

Description

technical field [0001] The invention relates to the technical field of machine tool equipment, in particular to a pressure balance device capable of preventing swelling of a liquid storage tank, a liquid storage tank and a machine tool cooler. Background technique [0002] At present, due to the limited use conditions, the product size of machine tool coolers is small, so only closed water tanks can be used. However, the air in the closed water tank cannot be discharged, and the unit runs with air in the circulating water, which seriously restricts the cooling effect of the unit, and the imbalance of atmospheric pressure inside and outside the water tank causes the water tank to bulge under pressure when water enters. Contents of the invention [0003] The invention discloses a pressure balance device capable of preventing the liquid storage tank from swelling, a liquid storage tank and a machine tool cooler, and solves the problem that the air in the closed liquid storage...
