The seated first valve body 7 is fixed via a rib 8, a through hole 9 is provided in the center of the first valve body 7, and a leakage drain pipe 10 is connected to the lower side of the through hole 9 to remove the leakage. The lower end of the liquid drain pipe 10 is made to protrude from the lower surface of the elbow 11 connected to the above-mentioned inlet 1 so as to be movable up and down, and a pipe-shaped auxiliary valve rod 12 is fitted to the outside of the valve mechanism 6 so as to be movable up and down. A second valve element 13, which is seated on the second valve seat 5, is fixed to the lower end of the sub-valve rod 12, and the second valve element 13 and the first valve element 7 are seated apart from each other. At the same time, the main piston 1 is placed inside the upper half of the upper surface of the valve body 3.
4, and a cylinder 16 containing an auxiliary piston 15 is fixed in the lower half thereof, and the above-mentioned main valve rod 6 is inserted into this cylinder 16, and the upper end of the main valve rod 6 is connected to the piston rod 17 of the main piston 14. The auxiliary valve rod 12 is inserted into the cylinder 16, and the upper end of the auxiliary valve rod 12 is inserted into the through hole 18 provided in the center of the auxiliary piston 15 so as to be vertically movable. The upper end of the width valve rod 12 protrudes above the auxiliary piston 15, and a flange 19 is provided at this protruding end, and the flange 19 and the auxiliary piston 1 are connected to each other.
5 means that the second valve body 13 is seated and the auxiliary piston 1
5 is a main spring 20 which presses down the main piston 14 between the top wall of the cylinder 16 and the main piston 14 so as to be separated from each other when in the lowered state, and a main spring 20 between the top wall of the cylinder 16 and the main piston 14, and between the main piston 14 and the flange 19
In between, the auxiliary springs 11 that push down the second valve body 13 are respectively inserted, and the main air holes 2 that feed compressed air to the lower surface of the main piston 14 are formed in the peripheral wall of the cylinder 16.

ある。 Next, when flowing fluid, compressed air is sent from the main air hole 22 to the main piston 14, piston rod 17, main valve rod 6, first valve body 7, and leakage drain pipe 1.
0 and as the first valve body 7 rises, the second valve body 13 and the sub-valve body 13 are brought into the open position (see Fig. 2), and when the cleaning liquid is to flow further, from the main air hole 22. does not supply air and sub air hole 23
The auxiliary piston 15 is supplied with compressed air from the chisel.
The flange 19, the auxiliary valve rod 12, and the second valve body 13 are raised, and the flange 19 is raised to the main piston 14.
By pushing up the piston rod 17, the main valve stem 6, the first valve body 7, and the leakage drain pipe 10, the first valve body 7 and the second valve body 13 are separated and moved to the open position ( (See Figure 3).
