The rotating rod 35 is connected to the adjusting plate 32 with a latch. The rotating rod 35 is rotatably connected to the valve body 10, the sealing plate 33 and the positioning plate 34. When the user needs to switch the working mode of the valve body 10 through the switching mechanism, he only needs to rotate the rotating rod 35. At this time, the rotating rod 35 will drive the adjusting plate 32 to rotate, thereby switching the working state.

[0072] The switching mechanism further includes: a rotating mechanism 40, which is used to rotate the rotating rod 35; specifically, the rotating mechanism 40 includes a gear 41 installed on the top of the rotating rod 35 and a screw rod 42 rotatably installed on the valve body 10, wherein the screw rod 42 is placed horizontally, the screw rod 42 is meshed with the gear 41, and the screw rod 42 is rotatably connected to the valve body 10; in addition, a handle 421 is also installed at the end of the screw rod 42, which can facilitate the user to rotate the screw rod 42.

[0073] Based on the above structure, a pointer 411 is also installed on the surface of the gear 41. The direction of the pointer 411 changes with the change of the gear 41. An arc groove is opened on the valve body 10, and the pointer 411 moves in the arc groove. There are also text labels 15 corresponding to the four working modes of the valve body 10 near the arc groove, which can help users know the working mode of the valve body 10 at this time.

[0074] The utility model also discloses a flow diversion control valve, comprising a valve body 10, the valve body 10 adopts the valve core structure for switching the mold water channel connection state;

[0075] The valve body 10 also includes:

[0076] The water distribution plate 50 is installed below the valve plate 31. A plurality of grooves 51 are formed on the water distribution plate 50. The number of the grooves 51 is the same as the number of the first through holes 314. The front end of each groove 51 is formed with a fourth through hole 511 connected to the water path of the mold water collection module 20. The rear end of the groove 51 corresponds to the first through hole 314.

[0077] 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 35, 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 35 also has an annular clamping cap 161, which is rotatably connected to the water distribution plate 50;

[0078] 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.

[0079] Based on the above structure, the self-locking mechanism includes:

[0080] A first groove 61 is formed at the end of the rotating rod 35, 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.

[0081] The limiting ball 64 is placed in the receiving groove;

[0082] 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 35 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;

[0083] like Fig.18As 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.

[0084] The detailed description of the states in each working mode based on the above structure is as follows:

[0085] 1. In the water flow mode, one of the second through holes 324 is connected to the ventilation channel 11, and the other second through hole 324 is connected to the water outlet channel 12, and two of the third adjustment spacers 323 overlap with the first valve plate spacers 311, so that the third valve plate water channel 303 is isolated from the first valve plate water channel 301 and the second valve plate water channel 302, as shown in FIG. Figure 6 and Figure 7 As shown, water flows through the ventilation channel 11 of the valve body 10 and then enters the valve plate water groove through the second through 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;

[0086] 2. In the pressure relief mode, one of the second through holes 324 is connected to the air inlet channel 13, and the other second through hole 324 is blocked, and one of the third regulating spacers 323 overlaps with the third valve plate spacer 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 through hole 324, and then discharged through the air inlet channel 13, so as to achieve the purpose of pressure relief;

[0087] 3. In the sewage discharge mode, refer to Fig.13, one of the second through holes 324 is connected to the air inlet channel 13, the other second through hole 324 is connected to the sewage channel 14, the second regulating spacer 322 overlaps with the third valve plate spacer 313, two of the third regulating spacers 323 overlap with the second valve plate spacer 312, and the first regulating spacer 321 overlaps with the first valve plate spacer 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, high-pressure gas is introduced into the air inlet channel 13, and the high-pressure gas enters the upper part through the second through hole 324 After passing through the first through hole 314 in the first valve plate water groove 301, it passes through the mold circuit, enters 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 returns to the mold circuit from the other first through hole 314, until it passes through the third valve plate water groove 303 and the second valve plate water groove 302, and finally is discharged from the first through hole 314 in the lower first valve plate water groove 301, and is discharged from the sewage channel 14 through the second through hole 324, so as to achieve the purpose of thoroughly cleaning all valve plate water grooves.

[0088] 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.
