[0024] The embodiments of the present application will be described in detail below with the accompanying drawings and examples, so that the implementation process of how to apply technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

[0025] Please refer to Figures 1 to 5 The embodiment of the present application provides a kind of edible oil filling line anti-drip sealing valve device, including valve body 1, the upper end of valve body 1 is communicated with feed pipe 101, the bottom of valve body 1 is communicated with discharge pipe 102, the lower end of discharge pipe 102 is provided with anti-drip assembly 6;

[0026] The anti-drip assembly 6 includes anti-drip sleeve 601, the lower end of anti-drip sleeve 601 is fixedly connected with annular plate 602, the top of annular plate 602 is provided with inwardly extending outer edge, the outer edge of annular plate 602 and the bottom of discharge pipe 102 form annular gap 4, the connecting port 603 of annular gap 4 is communicated with discharge pipe 102 along circumferential direction, and the connecting port 603 is communicated with suction pipe 606.

[0027] When using, connecting port 603 is communicated with suction pump inlet, edible oil enters valve body 1 from feed pipe 101, and is discharged from discharge pipe 102 to complete filling, after filling, close valve, start suction pump, and the oil drops remaining on the inner wall of discharge pipe 102 drop downward, when oil drop passes through annular gap 4, oil drop is quickly sucked into annular gap 4 under negative pressure, and then is collected into collecting barrel through suction pipe 606 and suction pump, all oil drops that drop along the inner wall of discharge pipe 102 can be collected without dead angle by the setting of annular gap 4, avoid the dripping phenomenon of edible oil filling line, effectively avoid the pollution of seepage oil drop to production line, and prevent the residual edible oil at pipe interface from being oxidized by air, accelerate the corrosion of pipe and the sealing property of connection.

[0028] In the embodiment, the suction pipe 606 is connected and communicated with the annular pipe 7 at the end away from the connecting port 603, and the annular pipe 7 is provided with a connecting pipe 701 communicated with the suction pump. After the device stops working, the edible oil remaining on the inner wall of the discharge pipe 102 will flow into the annular gap 4. The suction pump can be started to suck the edible oil remaining in the annular gap 4 into the annular pipe 7 for unified collection and treatment, thereby avoiding the dripping phenomenon of the edible oil at the discharge pipe 102.

[0029] In the embodiment, the distance between the top of the annular plate 602 and the bottom of the discharge pipe 102 is 0.5-1.5 mm. Through this setting, the outflow speed and stability of the edible oil during normal filling will not be affected. When the filling is stopped, the annular gap 4 can quickly form a negative pressure by using the suction pump, which is beneficial to the quick and complete extraction and collection of the oil drops remaining in the discharge pipe 2.

[0030] In the embodiment, the sealing ring 5 is arranged between the discharge pipe 102 and the drip-proof sleeve 601. After the drip-proof sleeve 601 is connected with the discharge pipe 102 through threads, the sealing ring 5 is deformed by extrusion to fill the small gap between the two and form a sealed structure. This effectively prevents the edible oil from leaking from the connection between the discharge pipe 102 and the drip-proof sleeve 601 during the filling process, ensures the sealing performance of the drip-proof assembly 6, and avoids material loss and equipment pollution caused by leakage.

[0031] In the embodiment, the outer wall of the drip-proof sleeve 601 is shaped to form a screwing part 605. When the drip-proof sleeve 601 is installed or removed, the operator can more conveniently hold and rotate the drip-proof sleeve 601. The screwing part 605 can be hexagonal.

[0032] In the embodiment, the outer wall of the valve body 1 is provided with the air cylinder 2. The top of the piston rod of the air cylinder 2 is fixedly provided with a connecting seat 201. The end of the connecting seat 201 away from the air cylinder 2 is fixedly connected with the valve rod 3. The valve rod 3 slides in the interior of the valve body 1. The lower end of the valve rod 3 is fixedly connected with the valve head 301 capable of plugging the discharge pipe 102. When it is necessary to start filling, the valve rod 3 drives the valve head 301 to move upward, so that the valve head 301 is separated from the discharge pipe 102. The edible oil can smoothly flow out of the valve body 1 through the discharge pipe 102 for filling. After the filling is completed, the valve rod 3 drives the valve head 301 to move downward. The valve head 301 plugs the discharge pipe 102 to block the flow of the edible oil, thereby achieving the closing of the valve. This pneumatic control mode can quickly and accurately control the actions of the valve rod 3 and the valve head 301, thereby meeting the needs of automatic filling production.

[0033] The working principle of the device will be described as follows. Figures 1 to 5

[0034] ​The cylinder 2 is started to work, the piston rod of the cylinder 2 is extended, the valve rod 3 is driven to ascend by the connecting seat 201, the valve head 301 is released from the plugging of the discharge pipe 102, the edible oil flows into the valve body 1 from the feeding pipe 101, and the filling is completed through the discharge pipe 102, it is to be explained that the annular gap 4 (the interval is 0.5-1.5mm) is extremely small to the oil flow resistance, and does not affect the filling speed (the filling efficiency is greater than or equal to 85 bottles / minute in actual measurement, and is flat with the traditional valve), after the filling is completed, the piston rod of the cylinder 2 is retracted, the valve rod 3 drives the valve head 301 to plugging the discharge pipe 102, at this time, the suction pump is started, the negative pressure (-0.02~ -0.05MPa) is formed in the annular gap 4, the oil drops remaining in the discharge pipe 102 flow into the annular gap 4, and the extraction and collection are completed through the suction pump, the suction pipe 606, the annular pipe 7 and the connecting pipe 701, the dripping phenomenon of the edible oil filling line is avoided, the oil drops leaking out are effectively avoided from polluting the production line, and the edible oil remaining at the pipeline joint is prevented from being oxidized by air, the corrosion speed of the pipeline is accelerated, and the sealing property of the pipeline connection is influenced.
