[0028] As a preferred embodiment of the present application, the stirring rod 116 is provided with a handle rod 121 at the top, a rubber sleeve 124 is sleeved on the surface of the handle rod 121, and a plurality of anti-skid strips 125 are arranged on the surface of the rubber sleeve 124.

[0029] Working principle: When working, the heating element 103a heats the cylindrical pipe 101 containing the molten metal 102 at an extreme temperature. A graphite plunger 108 is placed at the bottom of the cylindrical pipe 101, which is firmly installed on the graphite seal 109. The graphite plunger 108 coincides with the throat jet 110 of the lower compartment 111. There is an outlet 112 at the bottom of the bottom compartment 111, which can have a variable area according to the required flow downstream. The throat jet 110 guides the path of the molten metal 102 into the bottom compartment 111 and protects the connecting arm 113 and the universal joint 114. The connecting arm 113 connects the graphite plunger 108 to the actuator arm 107 through the universal joint 114. The actuator arm is locked in the upward position by the hinge mechanism 106. The hinge and the actuator arm 107 are protected by the insulating plate 105, which allows safe operation if the valve needs to be opened. When the actuator arm 107 is in the locked position, the graphite plunger 108 is firmly seated on the graphite seal 109. In addition, the vertical pressure and weight of the molten liquid 102 maintain the additional force on the graphite plunger 108. To open, it is only necessary to unlock the hinge 105 and press the actuator arm 107, which will vertically actuate the graphite plunger 108 and lift it from the graphite seal 109. When this happens, the molten material 102 begins to slowly enter the throat jet 110 into the bottom compartment 111 and the downstream flow of the compartment 111 can be controlled by selecting the desired outlet area 112.

The scope of the present application is defined by the appended claims and their equivalents.
