[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 - Figure 3The utility model provides an embodiment: a high-low pressure water system distribution valve group for mining, including a shell 1 for connecting various components, a water injection port 2 for connecting a water injection pipe is installed at the front end of the shell 1, and a regulating component 7 for realizing automatic water flow distribution is installed at the front end of the shell 1. The inner wall of the shell 1 is provided with a diversion component 9 for controlling water flow diversion. The diversion component 9 includes a high-pressure groove 91 for high-pressure water flow to pass through. The high-pressure groove 91 is arranged on the inner wall of the shell 1. The rear end of the water injection port 2 is connected to the high-pressure groove 91. The water flow injected into the water injection port 2 will directly enter the high-pressure groove 91. The front end of the high-pressure groove 91 is provided with a valve for connecting the high-pressure groove 91 and the low-pressure groove 9. The shell 1 has a connecting groove 92, and a low-pressure groove 93 for low-pressure water flow to pass through is arranged at the front end of the connecting groove 92. A low-pressure joint 8 for connecting a low-pressure pipeline is installed at the rear end of the shell 1. After the low-pressure water flow enters the interior of the high-pressure groove 91, it can enter the low-pressure groove 93 through the connecting groove 92. The front end of the low-pressure joint 8 is communicated with the low-pressure groove 93, and the water flow inside the low-pressure groove 93 can flow into other pipelines through the low-pressure joint 8. A high-pressure joint 10 for connecting a high-pressure pipeline is installed near the bottom end of the low-pressure joint 8 at the rear end of the shell 1. The front end of the high-pressure joint 10 is communicated with the high-pressure groove 91, and the high-pressure water flow entering the high-pressure groove 91 can flow into other pipelines through the high-pressure joint 10.

[0031] Reference Figure 3 - Figure 5 The regulating assembly 7 includes a valve body 71 for supporting the entire regulating assembly 7. The valve body 71 is installed through the front end of the housing 1. The right end of the valve body 71 is slidably connected to a valve core 72 for driving a connecting rod 73 to move. The right end of the valve core 72 is fixedly connected to a connecting rod 73 for driving a stopper 74 to move. The outer wall of the connecting rod 73 is fixedly connected to a stopper 74 for blocking the connecting groove 92. When the high-pressure water flow enters the interior of the connecting groove 92, the high-pressure water flow will squeeze the valve core 72 to force the valve core 72 to move to the left. At the same time, the valve core 72 will drive the stopper 74 to move to the left through the connecting rod 73. The connecting groove 92 is blocked, and the left end of the valve core 72 is fixedly connected to a reset spring 76 for driving the valve core 72 to move rightward and reset. The left end of the reset spring 76 is fixedly connected to the inner wall of the valve body 71. When the water flow pressure decreases, the thrust of the water flow on the valve core 72 will also decrease. At this time, the reset spring 76 will push the valve core 72 to the right to reset it to the right. The valve core 72 will drive the stopper 74 to move rightward through the connecting rod 73 to reopen the connecting groove 92. The rear end of the shell 1 is fixedly connected to a fixed sleeve 75 for accommodating the connecting rod 73, and the connecting rod 73 is inserted at the left end of the fixed sleeve 75.

[0032] Reference Figure 1 - Figure 3A safety valve 3 for protecting the high-pressure groove 91 is installed at the front end of the shell 1. The rear end of the safety valve 3 is interconnected with the high-pressure groove 91. The safety valve 3 is a prior art. When the water pressure inside the high-pressure groove 91 is too high, the spring inside the safety valve 3 will be squeezed and contracted, and the inside of the safety valve 3 will automatically connect and drain water to the outside to relieve the pressure of the high-pressure groove 91. Due to the prior art, this case will not be described in detail. A safety valve 26 for protecting the low-pressure groove 93 is installed at the front end of the shell 1 near the right end of the safety valve 3. The safety valve 26 has the same working principle as the safety valve 3. The rear end of the safety valve 26 is interconnected with the low-pressure groove 93. A safety valve 6 for detecting the high pressure inside the low-pressure groove 93 is installed at the front end of the shell 1. A small pressure sensor 4 is provided, and the rear end of the pressure sensor 4 is interconnected with the low-pressure groove 93. A pressure sensor 25 for detecting the internal pressure of the high-pressure groove 91 is installed at the front end of the shell 1 near the bottom of the pressure sensor 4. The rear end of the pressure sensor 25 is interconnected with the high-pressure groove 91. The inner wall of the connecting groove 92 is set to be circular. The circular groove can withstand greater pressure when in use and is more easily blocked. The connecting groove 92 is adapted to the block 74. The left and right ends of the block 74 are set to be conical, and the slope of the cone at the right end of the block 74 is greater than that at the left end. In this way, the thrust of the high-pressure water flow on the right end of the block 74 will also be greater than that on the left end. When the left end of the block 74 contacts the connecting groove 92, the connecting groove 92 will be blocked.

[0033] Reference Figure 1 - Figure 3 A low-pressure detection port 95 is provided at the top of the shell 1 for conveniently detecting the internal pressure of the low-pressure groove 93. The bottom end of the low-pressure detection port 95 is connected to the high-pressure groove 91. A high-pressure detection port 94 is provided at the top of the shell 1 near the front end of the low-pressure detection port 95 for conveniently detecting the internal pressure of the high-pressure groove 91. The bottom end of the high-pressure detection port 94 is connected to the connecting groove 92. The pressure inside the shell 1 is monitored in real time through the low-pressure detection port 95 and the high-pressure detection port 94.

[0034] Working principle: when water flows into the device through the water inlet 2, it will first enter the interior of the high-pressure groove 91, and will try to enter the interior of the low-pressure groove 93 through the connecting groove 92. When the water flow pressure is low, it can pass through the connecting groove 92 normally. When the water flow pressure is high, the water flow will squeeze the valve core 72 to drive the connecting rod 73 and the stopper 74 to move to the left. The movement of the stopper 74 to the left will block the connecting groove 92. At this time, the water flow will not be able to enter the interior of the low-pressure groove 93. When the water flow pressure decreases, the reset spring 76 will push the valve core 72 to the right to drive the connecting rod 73 and the stopper 74 to move to the right and reset, so that the connecting groove 92 will be reconnected.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
