[0021] 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.

[0022] Reference Figure 1-Figure 3 The utility model provides an embodiment: a control device of a control valve, comprising a valve body 1, a sealing groove 2 is provided on the inner side of the valve body 1, a locking block 3 is fixedly connected to the outer side of the valve body 1, a valve cover 4 is provided on the top of the valve body 1, a connecting pipe 5 is fixedly connected to the bottom of the valve cover 4, an annular groove 6 is provided on the outer side of the connecting pipe 5, a sealing ring 7 is sleeved on the inner side of the annular groove 6, a locking block 8 is fixedly connected to the outer side of the valve cover 4, a locking hole 9 is provided inside the locking block 3 and the locking block 8, a locking rod 10 is slidably connected to the inner side of the locking hole 9, a plug hole 11 is provided inside the locking rod 10, and the plug hole 1 1 is slidably connected with an insert rod 12, and a flow control component is arranged on the outside of the valve body 1. The flow control component is used to control the liquid flow inside the valve body 1. The sealing groove 2 cooperates with the sealing ring 7 to make the valve body 1 and the valve cover 4 more airtight after being assembled. First, the insert rod 12 is pulled out from the inside of the insertion hole 11, and then the locking rod 10 is pulled out from the inside of the two locking holes 9. In this way, the locking relationship between the locking block 2 8 and the locking block 1 3 is released, and then the valve cover 4 is lifted upward to separate the connecting pipe 5 from the valve body 1. This disassembly method is more convenient than the traditional method of removing bolts with tools.

[0023] Reference Figure 1-Figure 3The flow control assembly includes two flange pipes 15, one end of the flange pipe 15 is fixedly connected to the outside of the valve body 1, one of the flange pipes 15 is rotatably connected to a rotating rod 16, and a baffle plate 17 is fixedly connected to the outside of the rotating rod 16, and the outside of the baffle plate 17 is fitted with the inside of the flange pipe 15. A through hole 18 is opened inside the baffle plate 17, the outside of the connecting pipe 5 is slidably connected to the inside of the valve body 1, the outside of the sealing ring 7 is fitted with the inside of the sealing groove 2, and two fixing blocks 13 are fixedly connected to the outside of the valve body 1, and two fixing blocks 14 are fixedly connected to the outside of the valve cover 4. The outside of the fixing block 14 is connected to the two fixing blocks 13. The outer side of the fixed block 13 is slidably connected, and a flow meter is installed on the outside of the flange tube 15. The fixed block 13 and the fixed block 2 14 can cooperate to play a limiting role, so that the valve body 1 and the valve cover 4 are more stable when assembled. The baffle plate 17 is driven to deflect by rotating the rotating rod 16, and then the gap between the baffle plate 17 and the flange tube 15 will change, thereby changing the liquid flow rate inside the valve body 1. When the baffle plate 17 is fully closed, the liquid can flow through the through hole 18. At this time, the internal flow of the control valve is in a minimum state, and the liquid flow change can be observed through the flow meter, so that the liquid flow rate can be freely controlled.

[0024] Working principle: When the control valve needs to be disassembled, the plug rod 12 can be first pulled out from the inside of the plug hole 11, and then the locking rod 10 can be pulled out from the inside of the two locking holes 9 to release the lock between the locking block 2 8 and the locking block 1 3, and then the valve cover 4 can be lifted up to separate the connecting pipe 5 from the valve body 1. This disassembly method is more convenient than the traditional method of removing bolts with tools. In addition, by rotating the rotating rod 16 to deflect the baffle plate 17, the gap between the baffle plate 17 and the flange pipe 15 is changed to change the liquid flow inside the valve body 1. When the baffle plate 17 is fully closed, the liquid can flow through the through hole 18. At this time, the internal flow of the control valve is at the minimum state, and the liquid flow change can be observed through the flow meter, so that the liquid flow can be freely controlled.
