Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0021] See also Figure 1-5, the embodiment provided by the utility model: an automatic drainer, comprising a cylinder 1, one end of the cylinder 1 is fixedly sleeved with a cylinder cover 2, the top of the cylinder cover 2 is fixedly connected to a water inlet joint 12, one side of the cylinder cover 2 is fixedly connected to a water outlet joint 13, a bracket 11 is provided on the inner side wall of the cylinder cover 2, a drain screw 9 is inserted on the bracket 11, the drain screw 9 is hollow, one end of the drain screw 9 is inserted into the water outlet joint 13, the cylinder cover 2 is provided with a screw hole corresponding to the drain screw 9, the top of the bracket 11 is horizontally bent, the top of the bracket 11 There is a slot, and both sides of the slot are provided with a through hole connected. A float 3 is provided in the cylinder 1, and a connecting piece 16 is fixedly connected to one side of the float 3. One end of the connecting piece 16 is bent downward and clamped in the slot on the bracket 11. The connecting piece 16 is located on the outer wall on both sides of the slot and is fixedly connected with an axle pin 10. The axle pin 10 is slidably inserted into the through hole on the bracket 11. A sealing ring 17 is inserted on the connecting piece 16. The sealing ring 17 corresponds to the position of the drain screw 9. One end of the sealing ring 17 is conical. Specifically, the cylinder cover 2 The water inlet joint 12 on the cylinder cover is connected to the equipment, and the water outlet joint 13 on the cylinder cover 2 is connected to the outlet pipe. During drainage operation, water is introduced into the interior of the cylinder body 1 through the water inlet joint 12. When the drainage buoyancy is smaller than the weight of the float 3 and the pressure applied by the compressed air, the float 3 is in a parallel state. At this time, the sealing ring 17 on the connecting piece 16 blocks the drainage screw 9 and does not drain water. When the buoyancy and pressure tend to be balanced, the float 3 moves up slightly. At this time, a part of the sealing ring 17 leaks out of the drainage screw 9 to achieve drip drainage. When the buoyancy is greater than the weight of the float 3 and the pressure, the water inlet joint 12 is introduced into the cylinder body 1. When the pressure is generated, the sealing ring 17 completely leaks out of the hollow hole of the drain screw 9 to realize the drainage work; the bottom of the cylinder cover 2 is provided with a manual drainage port, and a positioning block 15 is fixedly connected to the manual drainage port. The positioning block 15 is provided with a manual drainage hole. A moving rod 7 is slidably inserted into the manual drainage hole. One end of the moving rod 7 is fixedly sleeved with a moving sleeve 5, and the other end of the moving rod 7 is fixedly connected with a manual drainage cover 8. Specifically, pressing the manual drainage cover 8 can cause the moving rod 7 to encounter a hole in the manual drainage hole. At this time, the moving sleeve 5 is separated from the cylinder cover 2 and leaks out of the manual drainage hole, which is convenient for manual drainage operations.

[0022] In this embodiment, a first O-ring 4 is provided in the cylinder cover 2, and the first O-ring 4 is against one end of the cylinder body 1 to increase the sealing effect of the connection; a spring 14 is provided on the moving rod 7, and the two ends of the spring 14 are fixedly connected to the positioning block 15 and the manual pressure cover 8 respectively, so as to facilitate the moving rod 7 to return to the initial position; the float 3 is made of polyurethane hard foam; the moving rod 7 is located on the side wall of the manual hole and is fixedly sleeved with a second O-ring 6 to increase the sealing between the manual hole.

[0023] Working principle: the water inlet joint 12 on the cylinder cover 2 is connected to the equipment, and the water outlet joint 13 on the cylinder cover 2 is connected to the outlet pipe. During drainage operation, water is introduced into the interior of the cylinder body 1 through the water inlet joint 12. When the drainage buoyancy is smaller than the weight of the float 3 and the pressure applied by the compressed air, the float 3 is in a parallel state. At this time, the sealing ring 17 on the connecting piece 16 blocks the drain screw 9 and does not drain. When the buoyancy and pressure tend to be balanced, the float 3 moves up slightly. At this time, the sealing ring 17 leaks out of a part of the drain screw 9 or the buoyancy and pressure tend to be balanced, the drainer starts to drain in a drip-like manner. When the buoyancy is greater than the weight of the float 3 and the pressure generated, the sealing ring 17 completely leaks out of the hollow mouth of the drain screw 9, and the drain outlet will open, working cyclically according to the size of the buoyancy.
