[0019] 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 belong to the scope of protection of the utility model.
[0020] The embodiment of the utility model is an automatic balancing device for a fan coil unit, comprising a cylinder 2, and a fixing frame 3 is installed inside the cylinder 2. Specifically, the fixing frame 3 comprises a sliding sleeve 31 located inside the cylinder 2, and the sliding sleeve 31 is coaxially arranged with the cylinder 2, and a plurality of fixing plates 32 are fixed at equal distances on the outer surface of the sliding sleeve 31, and one end of the fixing plate 32 away from the sliding sleeve 31 is fixedly connected to the inner side wall of the cylinder 2, and the setting of the fixing frame 3 plays a role in limiting the position of the fixing rod 4, and the fixing rod 4 is slidably installed inside the fixing frame 3, and the fixing rod 4 is close to the input end of the cylinder 2 A baffle plate 5 is installed, and a certain gap is left between the baffle plate 5 and the inner wall of the cylinder 2, so that the fluid can flow into the coil 1 from the gap between the cylinder 2 and the inner wall of the cylinder 2. It should be noted that the fluid can be cold water, hot water, low-temperature gas or high-temperature gas, so it can be selected according to the needs of the user, and no detailed description is given; an adjustment plate 7 is installed at the output end of the fixed rod 4 close to the cylinder 2, and a sealing ring 8 is installed at the output end of the cylinder 2. Through the cooperation of the adjustment plate 7 and the sealing ring 8, the size of the outlet of the cylinder 2 can be adjusted according to the size of the fluid. A rubber sleeve is installed on the opposite side of the adjustment plate 7 and the sealing ring 8, which can play a sealing role if the flow rate of the fluid is too large.
[0021] When the fluid enters the interior of the cylinder 2, if the flow rate of the fluid is large, it can impact the baffle plate 5. Under the action of the impact, the baffle plate 5 drives the fixed rod 4 to move and squeezes the spring 6. At this time, the spring 6 changes from the original state to the squeezed state; then the fixed rod 4 can push the adjusting plate 7 to move, so that the outlets of the adjusting plate 7 and the sealing ring 8 can become smaller; as the flow rate of the fluid slowly decreases, the impact force on the baffle plate 5 will also decrease. At this time, the squeezing force on the spring 6 decreases, and the spring 6 can push the baffle plate 5 to move, so that the baffle plate 5 drives the fixed rod 4 to move, so that the fixed rod 4 can drive the adjusting plate 7 to adjust, so that the spacing between the adjusting plate 7 and the sealing ring 8 can be adjusted, so that the opening of the cylinder 2 can be enlarged, so that the automatic balancing device can be automatically adjusted according to the size of the fluid, replacing the traditional manual adjustment method, thereby reducing the operation process of the staff and bringing convenience to the staff.
[0022] An exhaust device; including a housing 9, and a fan 10 is installed inside the housing 9. The number of the fans 10 can be one or more, and the number of the fans 10 can be selected according to the needs of the user. This application will not be described in detail; a coil 1 is installed at the air outlet of the fan 10. Through the setting of the coil 1, the air discharged by the fan 10 can be cooled or heated. The input and output ends of the coil 1 extend to the outside of the housing 9. It should be noted that a shock-absorbing rubber ring is provided at the connection between the housing 9 and the coil 1. Through the setting of the shock-absorbing rubber ring, the noise generated by vibration during the process of inputting fluid into the coil 1 is reduced, thereby improving the use effect of the device. An automatic balancing device is installed at the input end of the coil 1, and the automatic balancing device plays a role in controlling the fluid entering the coil 1; protective nets 11 are installed on both opposite sides of the housing 9. Through the setting of the protective net 11, the fan 10 and the coil 1 are protected, the phenomenon of damage to the coil 1 and the fan 10 due to collision is reduced, and the service life of the exhaust device is extended.
[0023] When in use, first connect the external air pump to the coil 1, then start the air pump and the fan 10 at the same time. The external fluid can be pumped into the coil 1 through the air pump 10, and the external gas of the shell 9 can be brought into and out of the shell 9 through the fan 10, so that the gas pumped into the shell 9 first passes through the coil 1 and then is discharged from the shell 9. The gas can be heated or cooled through the coil 1, and the heated or cooled gas can be discharged from the shell 9.
