Detailed Description
Please refer to fig. 1 to 4:
the invention provides a high-performance labyrinth regulating valve, which comprises a valve body 1, a valve cover 4, a flow guide disc 9 and a labyrinth disc 10, wherein each part of the high-performance labyrinth regulating valve is described in detail below;
the left end of the valve body 1 is provided with a valve body water inlet 3, the bottom of the tail end of the valve body water inlet 3 is fixedly connected with a valve seat 2, and the right end of the valve body 1 is provided with a valve body water outlet 7; specifically, a medium can enter the valve body 1 from the valve body water inlet 3, then flow regulation is carried out through the labyrinth disc 10 and the flow guide disc 9, and then the medium flows out through the valve body water outlet 7, so that the whole flow regulation is completed;
the valve cover is connected above the valve body 1 through a screw, the valve rod 5 is connected inside the valve cover 4 in a sliding mode, and the tail end of the valve rod 5 is fixedly connected with a valve core 6; specifically, the valve rod 5 can drive the valve core 6 to slide up and down on the inner walls of the labyrinth disc 10 and the diversion disc 9, so that the on-off quantity of the water outlets 902 of the diversion disc can be controlled, and the purpose of adjusting the required flow is achieved;
the labyrinth disc 10 is fixedly connected above the valve seat 2, a labyrinth disc water inlet 1001 is uniformly formed in the periphery of the labyrinth disc 10, first water distribution flow channels 1004 are formed in two sides of the labyrinth disc water inlet 1001, a flow distribution port 1002 is formed in the other end of each first water distribution flow channel 1004, a second water distribution flow channel 1005 is formed in the other end of each flow distribution port 1002, and a labyrinth disc water outlet 1003 is formed in the other end of each second water distribution flow channel 1005; specifically, the medium in the diversion disc water inlet 901 flows into the labyrinth disc water inlet 1001, then the labyrinth disc water inlet 1001 performs diversion decompression and deceleration by using the first diversion pipeline 1004, then the diverted medium performs secondary diversion decompression and deceleration by the second diversion pipeline 1005 of the diversion port 1002, so that the flow velocity of the medium is greatly reduced by multiple diversion deceleration, and the decelerated medium can flow into the diversion disc water outlet 902 above the diversion disc water outlet 1003 and flow out;
