A schematic cross-sectional view of the control valve in a fully open state. As shown in Fig. 2, the user moves the sleeve 131 of the shaft 110 in the movable space 132 inside the slide block 130 by pulling up the shaft 110. Therefore, when the shaft 110 is pulled up, the upper slider 120 is pulled up with the shaft 120, but the lower slider 130 does not start to move, but the sleeve 131 moves in the movable space 132, and The top end of the sleeve 131 and the inner side of the lower slider 130 are completed. 099111710 Form No. A0101 Page 9 / Total 20 pages 0992020723-0 201135103 Fully engaged. The relative distance between the upper slider and the lower slider 13 is such that the elastic member 145 between the right slider 150 and the left slider 140 contracts and shortens between the right slider 150 and the left slider 140. The distance between the disc-shaped pistons 17〇, 18〇 connecting the right slider 150 and the left slider 14〇 is also retracted so that it is no longer in contact with the inner edge of the second control valve body 200. [0016] As shown in FIG. 3, when the sleeve 131 is fully engaged with the innermost side of the sleeve 131, if the user continues to pull the shaft, the sleeve can be used. 131 abuts the lower slider 130 ′ and pulls up the upper slider 12 〇, the lower slider 13 〇, the right slider 150 and the left slider 14 〇 simultaneously, so that the disk-shaped pistons 17 〇 , 180 are also pulled up 'Until the projection U1 of the shaft 11捍 abuts against the inner edge of the first control valve body 1 ,, the entire pulling action cannot be performed. At this time, the two flow ports 210 and 220 are also simultaneously opened, and the crucible can be turned on. Please refer to Fig. 4, which is a side view showing the direction perpendicular to Fig. 1. As shown in Fig. 4, the disc-shaped piston 1M seals the flow port 22, and the disc-shaped piston 180 and the flow port 220 are both disk-shaped. The flow port 220 is opened by the up and down movement of the shaft 110 to conduct the liquid. Please refer to Fig. 5, which is a cross-sectional view of the hand wheel and the pressure relief door of the present invention. As shown in FIG. 5, the shaft 110 extends out of the first control valve body and has a threaded design at one end thereof, and includes a hand wheel 4〇〇 for applying a rotational force 'to drive the threaded design. The shaft 110 moves upward. In addition, the shaft 110 further includes a Gland 430, a sleeve (Sleeve) 420, and a packing 410 covering the shaft 11〇 to be more dense with the first control valve body 1 . Hehe. 099111710 Form No. A0101 Page 10 / Total 20 Page 0992020723-0 201135103 [0017] In addition, the two-way control valve of the present invention further has an auxiliary guide block 300 for connecting the upper slider, the lower slider, the right slider and the left slider, so that four The guide blocks are more interlocking. The upper slider abuts the auxiliary guide block 300 by the two connecting rods 121, and the connecting rod 121 has an accommodating space 122 at the point of abutting with the upper slider and the auxiliary guiding block 300. Therefore, when the shaft 110 is Pulling up, the upper slider will be pulled up with the shaft 120, and the lower slider will not move at the beginning. [0018] The bottom end of the second control valve main body 200 further includes a liquid discharge valve 500, which is fixed to the drainage groove, and the pressure relief valve 500 is used for discharging the first control valve main body 'body 100 and the second control valve An unnecessary dangerous liquid inside the main body 200, where the pressure relief valve 500 and the second control valve main body 200 are connected with a disc-shaped oil seal 510 to avoid the danger that the discharge valve 500 is not locked due to the fact that the pressure relief valve 500 is not locked. The liquid leaks out. The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the invention are intended to be included in the scope of the appended claims.
