Description

Technical Field

[0001] This utility model relates to the field of copper capillary technology, and in particular to a flow regulating device for anti-clogging copper capillary tubes. Background Technology

[0002] Copper capillary tubes are tubular products made of copper with very small diameters. They have relatively thin walls and a slender, tubular appearance. They are generally made of copper and brass and possess good flexibility and a series of excellent properties inherent to copper, making them widely used. In refrigeration systems, their small diameter creates significant resistance to the refrigerant, causing a decrease in refrigerant pressure and a change in flow rate. This allows the refrigerant to smoothly transform from a liquid to a gaseous state in the evaporator, absorbing a large amount of heat and achieving a cooling effect.

[0003] In refrigeration equipment applications, the ambient temperature is constantly changing. When the temperature rises, the refrigeration system needs to adjust the refrigerant flow rate to maintain a stable cooling effect. Relying solely on the fixed throttling characteristics of the copper capillary tube itself cannot flexibly cope with such changes. Therefore, a flow regulation device is required. Existing flow regulation devices mostly adopt a roller structure. This mechanism has the advantages of small space occupation and wide adjustment range. However, in actual use, the flow regulation is often not stable enough, which limits the application scenarios of the flow regulation device and increases the cost of flow regulation. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an anti-clogging copper capillary flow regulating device, which aims to improve the problem of poor regulation stability in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an anti-clogging copper capillary flow regulating device, comprising a flow tank, a connecting rod disposed at the center of the top surface of the flow tank, a turntable fixedly connected to the top of the connecting rod, multiple connecting plates fixedly connected to the center of the outer wall of the connecting rod, multiple extrusion rods fixedly connected to the bottom of the connecting plates, a limit ring fixedly connected to the bottom end of the extrusion rods, a spring barrel slidably connected to the outer wall of the limit ring, a compression spring fixedly connected to the inner wall of the spring barrel, a cover plate fixedly connected to the bottom end of the spring barrel, a cone fixedly connected to the bottom end of the cover plate, a baffle fixedly connected to the center of the inner wall of the flow tank, multiple through holes opened at the top of the baffle, and an anti-clogging mechanism connected to the left side of the inner wall of the flow tank, the anti-clogging mechanism being used to prevent clogging of the inner wall.

[0006] As a further description of the above technical solution: The anti-clogging mechanism includes a bend, the right end of which is connected to the left side of the inner wall of the flow tank. A filter plate is fixedly connected to the inner wall of the bend near its edge. A flow divider plate is connected to the top of the bend. Multiple circular grooves are formed on the top of the flow divider plate. A guide pipe is fixedly connected to the inner wall of the circular groove. A threaded cap is threadedly connected to the outer wall of the guide pipe. A branch pipe is connected to the bottom of the inner wall of the bend. A collection tank is connected to the bottom of the branch pipe. A drain pipe is connected to the bottom of the collection tank. A threaded cap is threadedly connected to the outer wall of the drain pipe.

[0007] As a further description of the above technical solution: A limiting cylinder is fixedly connected to the bottom of the inner wall of the flow tank, and the inner wall of the limiting cylinder is slidably connected to the outer wall of the connecting rod.

[0008] As a further description of the above technical solution: A limiting plate is fixedly connected to the upper part of the outer wall of the connecting rod, and an annular groove is provided on the outer wall of the connecting rod near the edge.

[0009] As a further description of the above technical solution: A rotating shaft is fixedly connected to the top right side of the flow tank, and a limit rod is rotatably connected to the outer wall of the rotating shaft.

[0010] As a further description of the above technical solution: A pointer is fixedly connected to the front side of the outer wall of the connecting rod, and the bottom of the pointer is slidably connected to the top of the flow tank.

[0011] As a further description of the above technical solution: A graduated ring is fixedly connected to the top of the flow tank near the edge, and a nameplate is fixedly connected to the front side of the outer wall of the flow tank.

[0012] As a further description of the above technical solution: A bottom pad is fixedly connected to the bottom of the flow tank, and a water outlet pipe is connected to the right side of the inner wall of the flow tank.

[0013] As a further description of the above technical solution: This utility model has the following beneficial effects: 1. In this utility model, by pulling the turntable upwards until the limiting plate touches the top of the inner wall of the flow tank, and then rotating the turntable to the corresponding flow scale on the scale ring, the corresponding connecting plate is perpendicular to the through hole position. The turntable is then pressed down, causing the cone to enter the inner wall of the corresponding through hole until the top of the cover plate and the baffle touch. At this time, the cone blocks the inner wall of the through hole, while the other two sets of non-corresponding connecting plates move down synchronously, squeezing and compressing the spring, and retracting the spring barrel and the squeezing rod. Through the above operation, the water flow can only flow through the corresponding through hole, achieving the purpose of stable flow regulation, increasing practicality and reducing the cost of use.

In addition, a filter plate is provided inside the bend to further prevent foreign objects from entering the flow tank and causing blockage. Foreign objects blocked by the filter plate flow into the collection tank under the action of gravity. When the device is not in use, the blockage inside the collection tank is removed through the threaded cap and the drain pipe, thus achieving the purpose of preventing blockage.

[0022] Working principle: When the copper capillary flow regulating device needs to be used, first assemble the copper capillary with the device, then start filling with water. The water flows into the inner wall of the flow tank 1 through the bend 206. When the flow needs to be adjusted, first pull the turntable 3 upwards until the limiting plate 14 on the outer wall of the connecting rod 4 touches the top of the inner wall of the flow tank 1. Then rotate the turntable 3 to the corresponding flow scale on the scale ring 19, so that the corresponding connecting plate 5 is perpendicular to the through hole 7 on the baffle 6. Then press the turntable 3 downwards to... The cone 13 on the connecting plate 5 moves down into the inner wall of the corresponding through hole 7 until the top of the cover plate 8 touches the top of the baffle 6. At this time, the cone 13 blocks the inner wall of the through hole 7, while the other two sets of non-corresponding connecting plates 5 move down synchronously, so that the cone 13 contacts the top of the baffle 6 and squeezes the compression spring 10, so that the compression rod 11 slides down the inner wall of the spring barrel 9, thereby shrinking the whole. After the flow rate is adjusted, the limiting rod 18 is rotated to lock it in the inner wall of the annular groove 16, restricting the position of the connecting rod 4. The anti-clogging mechanism 2 is designed to prevent blockage at the water inlet of the device. First, the threaded cap 204 is rotated upwards and removed. Then, the copper capillary tube and the guide tube 203 are assembled and connected. Any excess guide tubes 203 that do not require copper capillary tubes are connected by the threaded cap 204. By increasing the number of copper capillary tubes at the water inlet, the flow area of ​​the water is increased, reducing the possibility of blockage. In addition, the bend 206 is equipped with a filter plate 205 to further prevent foreign objects from entering the flow tank 1 and causing blockage. Foreign objects blocked by the filter plate 205 flow into the collection tank 208 under the action of gravity. When the device is not in use, the blockage inside the collection tank 208 is removed through the threaded cap 210 and the drain pipe 209, thus achieving the purpose of preventing blockage.
