The invention will now be described in further detail with reference to the drawings and specific examples, which are not intended to limit the invention thereto.
The embodiment of the invention provides a throttling device, which comprises a shell 1, an actuator 2 and a baffle plate 3, wherein an outlet 4 is formed in the shell 1, and the actuator drives the baffle plate 3 to move so as to adjust the size of the outlet 4.
In the technical scheme, the baffle plate 3 can be driven to move through the actuator 2, so that the relative position between the baffle plate and the outlet 4 is adjusted, the purpose of adjusting the size of the outlet 4 is achieved, the throttling quantity can be controlled more accurately, and the accurate control requirement of a medium-large-sized refrigerating machine system on the throttling quantity is met.
By adopting the technical scheme, the invention can realize wide load adjusting range and wide climate adaptation range, and can greatly improve the economy and reliability of the refrigerator in wide use occasions. In addition, the wide load adjusting range can improve the adaptability of the refrigerator to engineering load, reduce the start-stop times and improve the use comfort; the wide weather adaptation range can lead the refrigerator to have better economy in different seasons; the wide application occasions can meet the occasions with harsh running conditions of the refrigerator, such as the refrigerating reliability in lower-temperature weather, and the initial investment increased by users for meeting different running conditions is greatly reduced; the reliable throttling device can improve the reliability of the unit and reduce the maintenance expenditure of the user.
In a preferred embodiment, the outlet 4 in the present invention is in the shape of a sector of a circle. Accordingly, the baffle 3 comprises a connection plate 5 and a sector plate 6 for cooperation with the outlet 4, one side of the sector plate 6 being connected to the connection plate 5. Referring to fig. 6, when the actuator 2 receives the on or off signal, or when it is manually operated to turn on or off, the rotation amount is transmitted to the baffle 3, thereby changing the flow cross-sectional area of the outlet 4. Since the flow cross-sectional area a=npi/180 (R 2 2 -R 1 2 ) N is more than or equal to 0 DEG and less than or equal to 90 DEG, wherein R1 is the inner radius of the sector ring shape, and R2 is the outer radius of the sector ring shape, so that the flow cross-sectional area A linearly changes along with the rotation angle n.
Therefore, the large throttling device can be used for approximately linearly regulating the flow by adopting the matching of the fan-shaped annular outlet and the fan-shaped plate, so that the accurate control of the throttling quantity is realized, and the flow regulating range is 0-100%.
Preferably, a plurality of outlets 4 are formed in the side wall of the housing 1, and the plurality of outlets 4 are uniformly distributed along the circumferential direction of the housing 1. Correspondingly, the baffle 3 also has a plurality of sector plates 6 distributed evenly throughout the body in order to control the size of each outlet 4 correspondingly.
Preferably, at least one slag discharging groove 7 is formed on the surface of the fan-shaped plate 6 facing the side of the outlet 4, so as to achieve the purpose of preventing the blocking. More preferably, the slag discharging groove 7 is arc-shaped. A plurality of arc-shaped slag discharging grooves 7 may be concentrically provided on the sector plate 6. Preferably, an opening 19 at one end of the slag discharging groove 7 is formed at the circumferential end surface of the sector plate 6 to facilitate slag discharging, thereby eliminating or reducing the possibility of seizing. The circular arc-shaped slag discharging groove 7 can collect foreign matters in the system and discharge the foreign matters along with the fluid along one end opening 19, so that the rotating mechanism is prevented from being blocked.
Preferably, the housing 1 includes a cylinder 8 and a bottom plate 9 connected to the cylinder 8, the bottom plate 9 is disposed at an opening of a first end of the cylinder 8, and the outlet 4 is formed on the bottom plate 9. Preferably, the actuator 2 is mounted at the opening of the second end of the barrel 8. Preferably, the actuator 2 is connected to the baffle 3 by a connecting rod 10 passing through the cylinder 8. Preferably, the baffle 3 is located on the side of the base plate 9 remote from the actuator 2. Preferably, the circumferential side wall of the cylinder 8 is provided with an inlet 13. Wherein the arrows in fig. 3 show the direction of fluid flow, this L-shaped layout makes the throttle arrangement compact.
Preferably, the actuator 2 is an electric actuator or a manual actuator. Preferably, the actuator 2 is mounted at the opening of the second end of the cylinder 8 through a mounting plate 11, the first end of the connecting rod 10 is connected with the output end of the actuator 2, and the second end of the connecting rod 10 passes through a through hole on the mounting plate 11 and then is connected with the baffle 3.
Preferably, a sealing member 12 matched with the connecting rod 10 is installed at the through hole of the mounting plate 11. In this way, the actuator is isolated from fluid by the seal 12 (e.g., a gasket) to form a semi-enclosed structure, and if a handle is used in place of the electric actuator, the invention can be switched to a simple manual control mode. Therefore, the semi-closed transmission shaft is used for connection, and the requirements of electric control and manual control are met.
Preferably, the second end of the connecting rod 10 is connected to the baffle 3 by means of a transmission 14 pivotably arranged in a through hole 17 in the bottom plate 9.
Preferably, a first end of the transmission part 14 is fixedly connected with the baffle 3, and a second end of the transmission part 14 is formed with a clamping groove matched with an end of the second end of the connecting rod 10.
