specific Embodiment 1
[0016] Specific embodiment 1: as figure 1 As shown in the figure, the liquid automatic gate valve still includes a valve body 1, a valve cover 6, a valve stem 3 and a gate plate 2. The inner cavity of the valve body 1 is provided with a feed channel 13 and a discharge channel 5 on both sides, and the valve cover 6 covers the valve. On the top of the valve body 1, there are valve seats 9 on both sides of the inner cavity of the valve body 1. The lower end of the valve stem 3 passes through the valve cover 6 and enters the inner cavity of the valve body 1. The gate plate 2 is fixed on the lower end of the valve stem 3 and the valve seat 17. Matching, with the upward and downward movement of the valve stem 3, the opening and closing match is formed. In order to realize the use of medium pressure as power, the liquid automatic gate valve is also provided with a valve stem driving oil cylinder 12 and a changeover switch 14 . like figure 2 , 3 As shown, the valve rod driving oil...
specific Embodiment 2
[0019] Specific embodiment 2: as Figure 7 As shown in the figure, the valve rod driving cylinder 12 in the liquid automatic gate valve can also be set upside down, that is, the valve rod driving cylinder 12 is arranged above the valve body 1, the second piston chamber is on the top, the first piston chamber is on the bottom, One end of the piston rod 10 protrudes from the bottom of the first piston cavity and is linked with the upper end of the valve rod 3. The inner cavity of the oil cylinder is divided into three parts by the first piston 4 and the second piston 8: that is, it belongs to the first piston 4 and the second piston 8. The lower part of the first piston chamber of the piston chamber (ie the part at the end of the closing direction); the upper part of the second piston chamber (ie the part at the end of the opening direction) that completely belongs to the second piston chamber and the part between the first piston 4 and the second piston 8 The portion where the ...
