[0076] 1. In the water flow mode, one of the second water holes 324 is connected to the water inlet channel 11, and the other second water hole 324 is connected to the water outlet channel 12, and two of the third adjustment ribs 323 overlap with the first valve plate rib 311, so that the third valve plate water groove 303 is isolated from the first valve plate water groove 301 and the second valve plate water groove 302, as shown in FIG. Figure 6 and Figure 7 As shown, water flows through the water inlet channel 11 of the valve body 10 and then enters the valve plate water groove through the second water hole 324. The water cannot enter the first valve plate water groove 301 and the second valve plate water groove 302 through the third valve plate water groove 303, and can only enter the mold water collection module 20 through the first through hole 314, enter the water path in the mold, and then return to the mold water collection module 20 and flow from the first through hole 314 of the first valve plate water groove 301 and the second valve plate water groove 302 to the first valve plate water groove 301 and the second valve plate water groove 302, and then flow out from the water outlet channel 12 of the valve body 10;

[0077] 2. In the pressure relief mode, one of the second water holes 324 is connected to the ventilation channel 13, and the other second water hole 324 is blocked, and one of the third regulating ribs 323 overlaps with the third valve plate rib 313, so that the third valve plate water groove 303, the second valve plate water groove 302 and the first valve plate water groove 301 are connected to each other, and the third valve plate water grooves 303 are isolated, so that the water path of the mold and the circuit inside the switching mechanism are connected in series, and the first valve plate water groove 301, the second valve plate water groove 302 and the third valve plate water groove 303 are connected in series, so that the gas in the mold can directly pass through the first valve plate water groove 301, the second valve plate water groove 302 and the third valve plate water groove 303 and finally be discharged from the second water hole 324, and then discharged through the ventilation channel 13, so as to achieve the purpose of pressure relief;

[0078] 3. In the sewage discharge mode, refer to Fig.13, one of the second water holes 324 is connected to the ventilation channel 13, and the other second water hole 324 is connected to the sewage channel 14, the second regulating rib 322 overlaps with the third valve plate rib 313, wherein two third regulating ribs 323 overlap with the second valve plate rib 312, and the first regulating rib 321 overlaps with the first valve plate rib 311, so that the first valve plate water groove 301, the second valve plate water groove 302 and the third valve plate water groove 303 are isolated from each other. At this time, the first valve plate water groove 301, the second valve plate water groove 302 and the third valve plate water groove 303 are in parallel state, and high pressure gas is introduced into the ventilation channel 13. The high-pressure gas will enter the first through hole 314 in the first valve plate water groove 301 in the upper part through the second water hole 324, and after passing through the mold circuit, enter from the first first through hole 314 in the third valve plate water groove 303 and the second valve plate water groove 302, and then return to the mold circuit from the other first through hole 314, until the third valve plate water groove 303 and the second valve plate water groove 302 have passed through them once, and finally discharged from the first through hole 314 in the first valve plate water groove 301 in the lower part, and discharged from the sewage channel 14 through the second water hole 324, so as to achieve the purpose of thoroughly cleaning all valve plate water grooves.

[0079] The above-mentioned sewage discharge mode and pressure relief mode are the switching of the connectivity relationship between the valve plate water groove and the mold water channel between series and parallel. In the series mode, the gas can release pressure smoothly. In the parallel mode, the high-pressure gas can flow fully to each valve plate water groove, so as to clean the valve plate water groove more thoroughly. It can be suitable for different working modes.

[0080] 4. In the water shut-off mode, the water inlet channel 11, the water outlet channel 12, the air vent channel 13 and the sewage discharge channel 14 of the valve body 10 are all blocked.

The rear end of the groove 51 corresponds to the first through hole 314.

[0085] The switch rod 16 is rotatably connected to the mold water collection module 20 after passing through the valve body 10 and the rotating rod 43, so as to enable the valve body 10 and the mold water collection module 20 to be quickly connected; further, the portion of the switch rod 16 extending from the rotating rod 43 also has an annular clamping cap 161, which is rotatably connected to the water distribution plate 50;

[0086] In addition, the annular cap 161 is provided with a self-locking mechanism for preventing the switch rod 16 from rotating when the valve body 10 is in the water flow mode, sewage discharge mode or pressure relief mode, and allowing the switch rod 16 to rotate when the valve body 10 is in the water shut-off mode.

[0087] Based on the above structure, the self-locking mechanism includes:

[0088] A first groove 61 is formed at the end of the rotating rod 43, a second groove 62 is formed at the upper surface of the annular clamping cap 161, and a third groove 63 is formed on the water dividing plate 50. The second groove 62 and the third groove 63 form a complete receiving groove.

[0089] The limiting ball 64 is placed in the receiving groove;

[0090] like Fig.17 As shown, when the valve body 10 is in the water flow mode, sewage discharge mode or pressure relief mode, the position of the first groove 61 is misaligned with the receiving groove. At this time, the limiting ball 64 is pressed by the end of the rotating rod 43 and cannot move up and down, thereby limiting the receiving groove from splitting. At this time, when the user rotates the switch rod 16, the switch rod 16 will drive the annular clamping cap 161 to rotate, and the position of the second groove 62 will also change. However, since the limiting ball 64 cannot move, the position of the second groove 62 is kept in place by the limiting ball 64, and the limiting ball 64 will conflict with the inner wall of the second groove 62, thereby causing the annular clamping cap 161 to be unable to rotate. Similarly, the switch rod 16 will be unable to rotate due to the existence of the limiting ball 64;

[0091] like Fig.18 As shown, when the valve body 10 is in the water-off mode, the first groove 61 corresponds to the accommodating groove, so that the limiting ball 64 has space to move up and down. When the user rotates the switch rod 16, the switch rod 16 will drive the annular clamping cap 161 to rotate. When the annular clamping cap 161 rotates, the position of the second groove 62 will also change. As the annular clamping cap 161 rotates, the limiting ball 64 will be pushed upward by the inner wall of the second groove 62. When the limiting ball 64 is pushed into the first groove 61, the annular clamping cap 161 is no longer restricted by the limiting ball 64, and the user can smoothly rotate the switch rod 16 to avoid the switch rod 16 being accidentally touched and rotated in the non-water-off mode.
