[0021] As Figure 1 and Figure 2 shown, a control device for opening and closing the pipe orifice of a lead liquid delivery pipe includes a delivery pipe 1. The liquid outlet of the delivery pipe is vertically downward. The delivery pipe includes a first pipe body 101, a second pipe body 102, and a transition pipe body 103. The first pipe body is connected to the transition pipe body, and the transition pipe body is connected to the second pipe body. The transition pipe body is an arc structure to ensure the stability of lead liquid delivery. The opening of the second pipe body is vertically downward. A support frame 2 is connected to the delivery pipe. A clamp is detachably connected to the outside of the delivery pipe. The clamp is assembled by two clamp monomers 8 with bolts 9. The support frame is connected to one of the clamp monomers to facilitate the disassembly and assembly of the delivery pipe and the support frame. A balance rod 3 is rotatably connected to the support frame. One end of the balance rod is provided with a weight suspension seat 4. A weight block 5 is detachably assembled on the weight suspension seat. The number of weight blocks can be freely increased or decreased according to needs. The other end of the balance rod is hinged with a suspension bracket 6. A plug 7 is provided on the suspension bracket. The upper end of the plug is conical and is in mating connection with the liquid outlet of the delivery pipe. Using the lever principle, the lifting movement of the plug is controlled by changing the number of weight blocks, so as to achieve the opening and closing of the pipe orifice of the delivery pipe and the control of the lead liquid flow rate. An anti-splash baffle 12 ( Figure 1 not shown in

[0022] As Figure 1 and Figure 2As shown in the figure, the counterweight suspension seat includes a lifting ring 401, a suspension rod 402, and a base 403. The upper end of the suspension rod is connected to the lifting ring, and the lower end is threadedly connected to the base, which is convenient for disassembly and assembly. The counterweight block bears on the base. A notch 501 is provided on the counterweight block, and the inner diameter of the notch is larger than the outer diameter of the suspension rod, which is convenient for increasing or decreasing the number of counterweight blocks. To further increase the adjustability of the lever, at least two limiting grooves 301 are evenly spaced along the length direction of the balance rod. The lifting ring is connected in cooperation with any one of the limiting grooves. By changing the position of the lifting ring on the balance rod, the lever arm of the lever can be changed.

[0023] As Figure 1 and Figure 2 shown in the figure, the suspension bracket includes a top beam 601, a bottom ring 602, and two vertical rods 603. The lower ends of the two vertical rods are symmetrically connected to both sides of the bottom ring, and the upper ends are connected to the top beam through nuts 10. A connecting rod 11 is connected between the plug and the bottom ring, which is convenient for disassembly and assembly and is conducive to maintenance and repair.

[0024] The working principle of the present utility model is as follows:

[0025] As Figure 1 and Figure 2 shown in the figure, the molten lead liquid is conveyed by the conveying pipe 1. On the counterweight suspension seat 4, the counterweight block 5 is reduced or the lifting ring 401 is moved towards the end close to the conveying pipe 1 to reduce the lever arm of the lever, so that the end of the balance rod 3 close to the counterweight suspension seat 4 moves upward, and the suspension bracket 6 drives the plug 7 to move downward, so that the plug 7 is away from the pipe orifice of the conveying pipe 1, thereby achieving the purpose of discharging liquid or increasing the lead liquid flow rate; on the contrary, increasing the counterweight block 5 or moving the lifting ring 401 towards the end away from the conveying pipe to increase the lever arm of the lever, so that the end of the balance rod 3 close to the counterweight suspension seat 4 moves downward, and the suspension bracket 6 drives the plug 7 to move upward, so that the plug 7 is close to the pipe orifice of the conveying pipe 1, thereby achieving the purpose of stopping liquid discharge or reducing the lead liquid flow rate. In addition, in actual use, the plug of the present utility model is made of iron material, and the pipe orifice of the conveying pipe is placed in the pouring pot. When the plug is submerged in the lead liquid, due to the density of iron being less than that of the lead liquid, the upward buoyancy obtained by the plug itself can also be used to increase the force of the lever to achieve the sealing of the pipe orifice.

[0026] The above shows and describes the basic principles, main features, and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
