[0002] In order to increase the gas-liquid separation effect, the existing gas-liquid separation device sets a spiral circuit for the gas and liquid, so that the gas and liquid can produce a centrifugal effect, so that the small droplets inside the gas and liquid are thrown out under the centrifugal action, thereby increasing the gas-liquid separation effect. However, it is impossible to make the device install both horizontally and vertically. For example, the gas-liquid separation cylinder disclosed in the Chinese patent, its application number is: CN201220112272.7, which is provided with a swirl plate. The spiral guide groove of the swirl plate can make the gas and liquid rotate in the groove, and the small droplets are thrown out from the liquid collecting hole under the action of centrifugal force, thereby achieving the purpose of gas-liquid separation. However, when the device is installed horizontally, the gas and liquid cannot flow according to the expected circuit, so it can only be installed vertically. Utility Model Content

[0003] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art, and to provide a gas and liquid separation device for refrigeration equipment, in which the spiral tube inlet is arranged directly above the liquid inlet, the liquid outlet is arranged at the lower right corner of the tank body, a rotatable connecting rod and an inclined plate are arranged on the side surface of the oil collecting tank, so that the device can not only be installed vertically, but also is suitable for horizontal installation with the liquid inlet pipe facing upward, which does not affect the flow of internal refrigerant and gas, liquid and oil, and increases the versatility and compatibility of the device.

[0004] The utility model also provides a gas and liquid separation device for a refrigeration equipment as mentioned above, comprising: a tank body, a liquid inlet pipe is provided on the side surface of the tank body, an air outlet pipe is provided on the top of the tank body, the air outlet pipe is connected to a spiral tube, the end of the spiral tube away from the air outlet pipe is located directly above the liquid inlet pipe, and a diverter plate is fixedly connected to the inside of the tank body; a liquid outlet pipe, the liquid outlet pipe is provided at the lower right corner of the tank body, a float valve body is provided inside the liquid outlet pipe, the float valve body is rotatably connected to a connecting rod, and the connecting rod is rotatably connected to a float at one end away from the float valve body; an oil outlet pipe, the oil outlet pipe is provided at the lower end of the tank body, the oil outlet pipe is connected to an oil guide pipe, an oil valve is provided inside the oil guide pipe, one end of the oil outlet pipe is connected to an oil collecting tank, and an inclined plate is provided on the side surface of the oil collecting tank. Through the above components, the spiral tube inlet is arranged directly above the liquid inlet, the liquid outlet is arranged at the lower right corner of the tank body, and a rotatable connecting rod and an inclined plate are arranged on the side surface of the oil collecting tank. This allows the device to be installed not only vertically, but also horizontally with the liquid inlet pipe facing upward, without affecting the flow of internal refrigerant and gas, liquid and oil, thereby increasing the versatility and compatibility of the device.

[0005] According to the utility model, a gas-liquid separation device for refrigeration equipment includes a groove on the surface of the diverter plate and an inclined position on one side of the oil collecting trough opening. These components guide the liquid to flow toward the bottom of the tank under gravity, preventing the gas from being blocked by the oil collecting trough and unable to rise toward the spiral tube.

[0006] According to the gas and liquid separation device for refrigeration equipment of the present invention, the inclined plate is concave on the surface of the oil collecting tank and contacts the connecting rod when installed horizontally. With these components, the float valve can operate more smoothly when installed horizontally.

[0007] According to the utility model, the gas-liquid separation device for refrigeration equipment has a spiral tube that spirals upward, and the outer side of the spiral tube is fixedly connected to the interior of the tank. With these components, the contact area between the gas and liquid and the spiral tube can be increased, making the gas-liquid separation process more stable.

[0008] According to the gas and liquid separation device for refrigeration equipment of the present invention, filters are installed inside the liquid outlet pipe and the oil outlet pipe, and the filters are located at the outlet of the liquid outlet pipe and the oil outlet pipe. These components filter out impurities in the oil to prevent them from affecting the refrigeration equipment.

[0009] According to the utility model, the gas and liquid separation device for refrigeration equipment comprises a connecting rod configured as a rotatably connected long rod that can only rotate about the X-axis. This arrangement allows the float to float upward even when installed horizontally, preventing the connecting rod from becoming stuck in the oil sump due to its inability to rotate toward the inclined plate surface.

[0010] According to the gas and liquid separation device for refrigeration equipment of the present invention, a partition is fixedly connected to the interior of the tank body, and the partition is located directly above the inlet of the spiral tube. With these components, gas accumulation at the top of the tank body can be reduced.

[0011] According to the gas and liquid separation device for refrigeration equipment described in the utility model, the interior of the partition is fixedly connected to the outer side of the spiral tube, and the fixed partition increases its stability.

[0012] Beneficial effects:

[0013] Compared with the prior art, the utility model arranges the spiral tube inlet just above the liquid inlet, the liquid outlet at the lower right corner of the tank body, and arranges a rotatable connecting rod and an inclined plate arranged on the side surface of the oil collecting tank, so that when the device is installed vertically, the float floats upward and can normally control the float valve body to prevent the liquid from flowing into the oil collecting tank or the air outlet pipe. When the device is installed horizontally, the float drives the connecting rod to rotate, driving the connecting rod to contact the inclined plate arranged on the side surface of the oil collecting tank. When the float floats upward, the inclined plate on the oil collecting tank can be used as a fulcrum to control the float valve body, and the water level can still be controlled normally. Due to the special design that the spiral tube inlet is arranged just above the liquid inlet pipe and the oil collecting tank opening, the liquid will still not flow into the air outlet pipe or the oil collecting tank when installed horizontally, that is, the device can not only be installed vertically but also supports horizontal installation, which does not affect the flow of internal refrigerant and gas, liquid and oil, and increases the versatility and compatibility of the device.
