A valve has valve bodies (1, 2), a tube (3) of an elastic material, extending through the valve bodies, and a roller (23) and a pressing surface (14) that are oppositely arranged with the tube (3) in between. When the roller (23) is caused to approach the pressing surface (14), the tube (3) is crushed between the roller (23) and the pressing surface (14) to close a flow path in the tube (3). When the roller (23) is moved along the tube (3), a crushing position where the roller (23) and the pressing surface (14) crush the tube (3) can be moved along the flow path axis of the tube (3) with the flow path closed.

The invention belongs to the technical field of corrosion and protection, and in particular relates to a casting method of an aluminum alloy sacrificial anode. The present invention firstly adds electrolytic primary aluminum liquid into the resistance furnace, then adds zinc ingots to form aluminum alloy liquid, then uses argon-loaded refining agent to carry out jet refining on the aluminum alloy liquid, and passes argon into the aluminum alloy melt after refining After degassing, use a slag removal tool to remove the oxidized scum on the surface of the aluminum alloy melt, and then add low melting point metal elements to the aluminum alloy melt. After the low melting point metal is pressed in, the melt is electromagnetically stirred , and then carry out ceramic filtration, pour the aluminum alloy melt into the preheated iron anode mold at a uniform pouring speed at 700-740°C, wait for the alloy melt to fill the mold, cool and solidify, and then take it out from the mold. An aluminum alloy sacrificial anode is obtained. The invention has the characteristics of short smelting time, small oxidation burning loss, good degassing and impurity removal capabilities, and low smelting cost.
