Description

Technical Field

[0001] The invention relates to the technical field of gate valves, and in particular to a gate valve with an automatic cleaning function. Background Art

[0002] The gate valve is a commonly used valve type, mainly used to fully open or close the flow of fluid in the pipeline. Its working principle is that the movement direction of the gate is perpendicular to the direction of the fluid, and the gate of the gate valve moves linearly with the valve stem. There is usually a trapezoidal thread on the lifting rod. The rotary motion is converted into linear motion through the nut at the top of the valve and the guide groove on the valve body. When the application environment has strict requirements, such as in the food processing industry, the gate valve needs to be automatically cleaned to reduce the risk of cross contamination. Among them, the filter is most susceptible to contamination.

[0003] In the existing patent CN117967817A, a gate valve with an automatic cleaning and filtering structure and a method of using the same are disclosed. The gate valve includes a water tank, a positioning tube is fixedly installed on the top of the water tank, a valve shell is fixedly installed on the top of the positioning tube, and a water inlet end and a water outlet end are fixedly installed on both sides of the valve shell. After the water receiving pipe is connected to the water delivery pipe, the present invention can transport water to the gate valve, and a filter is arranged in the water inlet end to filter the water. After that, when the handle is turned, the gate valve can be closed, and the filter can be rotated 180° at the same time, and then the filter can be flushed, so that the filter can be cleaned, so that it has good convenience in actual use.

[0004] In the above structure, the filter screen can be cleaned. However, when the filter screen is cleaned, when the liquid flows, the pollutants on the filter screen will fall off. The pollutants will flow with the pipeline and will still cause liquid contamination in the pipeline, which is not conducive to the cleaning of the filter screen and can easily cause contamination or even blockage of downstream equipment, increase the risk of cross-contamination, reduce the self-cleaning function of the device, reduce the quality of the liquid, and affect product quality.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0030] Embodiment 1: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, a gate valve with automatic cleaning function of the present invention comprises a mounting plate 1, a support plate 2 is arranged on the mounting plate 1, a pipeline 3 is installed on the support plate 2, a control component 4 for controlling liquid flow is arranged on the pipeline 3, a filter component 5 is arranged on the pipeline 3 at the upstream of the control component 4, and an impurity detector 6 for detecting liquid impurities is arranged on the pipeline 3 at the downstream of the control component 4; an operating component 7 is arranged on the control component 4, and the operating component 7 is used to drive the opening and closing of the control component 4, a connecting component 8 connected to the filter component 5 is arranged on the control component 4, and an adjusting component 9 for adjusting the connecting component 8 is arranged on the control component 4; a liquid storage component 10 connected to the pipeline 3 is arranged on the support plate 2, a cleaning component 11 for flushing the filter component 5 is arranged on the liquid storage component 10, and a liquid storage component 12 connected to the pipeline 3 is arranged on the mounting plate 1, and when the liquid storage component 12 accumulates liquid, the liquid storage component 12 forces the liquid storage component 10 to press downward.

[0031] Working principle: When the liquid passes through the pipeline 3 normally, the filter component 5 is used to filter the liquid. The liquid passes through the upstream of the pipeline 3, the control component 4 and the downstream of the pipeline 3 and is transported to the use equipment. When the flow rate needs to be adjusted, the control component 4 is operated by the operating component 7 to move the control component 4 to a reasonable position; when the liquid in the pipeline 3 is detected, the operating component 7 is used to force the control component 4 to move to the maximum opening. At this time, the flow rate is the largest, which is convenient for detecting liquid impurities. When impurities accumulate on the filter component 5, the impurity detector 6, such as a turbidity meter, is used to detect impurities in the liquid downstream of the pipeline 3. When impurities are detected, the filter component 5 needs to be cleaned, and the connecting component 8 is adjusted by the adjusting component 9 to force the connecting component 8 to connect with the operating component 7. The operating component 7 is used to force the control component 4 to close the pipeline 3. At the same time, the connecting component 8 forces the filter component 5 to rotate to a reasonable position. When the pipeline 3 is closed, due to the impact force generated by the liquid, the liquid is continuously introduced into the liquid storage component 10 to a reasonable height, that is, the liquid storage component 10 is in contact with the liquid storage component 12, and the liquid storage component 12 is opened to close this section of the pipeline 3. The liquid containing impurities in the filter assembly 5 is released until the filter assembly 5 is exposed, and the last section of liquid is introduced into the liquid storage assembly 12 for accumulation, forcing the liquid storage assembly 12 to produce a gravity effect, and the liquid storage assembly 12 produces a downward pressure on the liquid storage assembly 10, forcing the liquid storage assembly 10 to produce a pressure effect. At the same time, under the action of the liquid storage assembly 10 itself, the liquid in the liquid storage assembly 10 is forced to be introduced into the cleaning assembly 11, and the exposed filter assembly 5 is continuously flushed by the cleaning assembly 11, so that the filter assembly 5 is automatically cleaned; in summary, a gate valve with an automatic cleaning function can use the impact force and pressure of the liquid to store the liquid when impurities are detected, and at the same time, a part of the liquid containing impurities can be released to completely remove the contaminated liquid to avoid liquid circulation. In the next operation, another part of the liquid is accumulated to produce a gravity effect, and the stored liquid is sprayed onto the filter assembly 5. The stored liquid is used for automatic cleaning, which is beneficial to the cleaning of the filter assembly 5, reduces the pollution of downstream equipment, reduces the risk of cross contamination, improves the self-cleaning function of the device, improves the quality of the liquid, and thus improves the product quality.

[0039] like Figure 1 and Fig.10 As shown, a gate valve with automatic cleaning function of the present invention, the liquid storage component 12 includes a support outer rod 1201 arranged on the mounting plate 1, a support inner rod 1202 is inserted into the support outer rod 1201, a force plate 1203 is arranged on the support inner rod 1202, a spring 1204 is arranged between the force plate 1203 and the mounting plate 1 and is sleeved on the outer ring of the support outer rod 1201 and the support inner rod 1202, and a storage component 12 is placed on the force plate 1203. Liquid tank 1205, a liquid infusion tube 1206 is arranged between the liquid storage tank 1205 and the pipeline 3, the position where the liquid infusion tube 1206 is connected to the liquid storage tank 1205 is made of soft material, a discharge tube 1207 is arranged on the liquid storage tank 1205, a solenoid valve three 1208 is installed on the liquid infusion tube 1206, a solenoid valve four 1209 is installed on the discharge tube 1207, and a lower pressure rod 12010 corresponding to the contact plate 1005 is arranged on the liquid storage tank 1205.

[0040] like Figure 2 and Figure 6 As shown, a gate valve with automatic cleaning function of the present invention is provided with a limit assembly 13 for limiting the rotation of a transmission rod 803 on a fixed plate 405, the limit assembly 13 includes a limit gear 1301 fixedly sleeved on the transmission rod 803, a connecting rod 1302 is provided on the fixed plate 405, and a pin 1303 meshing with the limit gear 1301 is provided on the connecting rod 1302.

[0041] Working principle: When the liquid passes through the pipeline 3 normally, the filter screen 502 is used to filter the liquid. The liquid passes through the upstream of the pipeline 3, the through hole 403 on the valve plate 402 and the downstream of the pipeline 3, and is transported to the use equipment. When adjusting the liquid flow, the operating rod 701 is rotated, and the operating rod 701 drives the active bevel gear 703 to rotate and drives the driven bevel gear 704 to rotate, so that the threaded rod 406 rotates. Under the action of the fixed plate 405, the threaded rod 406 drives the connecting plate 407 to move to a reasonable position, the connecting plate 407 drives the valve stem 404 to move, and the valve stem 404 drives the valve plate 402 to move, so that the through hole 403 is adapted to the inner diameter of the pipeline 3. When the through hole 403 is completely aligned with the pipeline 3, the valve plate 402 is in a fully open state, allowing the liquid to pass normally.

[0042] When testing the liquid in the pipeline 3, the operating rod 701 is rotated to force the valve plate 402 to move to the maximum opening, that is, the through hole 403 is aligned with the inner diameter of the pipeline 3. At this time, the liquid flow rate is the largest, which is convenient for detecting liquid impurities. When impurities accumulate on the filter screen 502, the impurity detector 6, such as a turbidity meter, is used to detect impurities in the liquid in the downstream of the pipeline 3. Impurities will be detected. At this time, the filter screen 502 needs to be rinsed, and the threaded rod 902 is rotated. Under the action of the guide plate 901, the movable plate 903 is forced to move, so that the movable plate 903 drives the transmission rod 803 to move to a reasonable position, and the transmission rod 803 drives the clamping gear 805 to move to a reasonable position on the inner gear ring 1 506 and the inner gear ring 2 802. The clamping gear 805 is always meshed with the inner gear ring 1 506 and the inner gear ring 2 802. At the same time, the transmission rod 803 drives the driven gear 804 to move to mesh with the driving gear 702, and the limit gear 1301 is separated from the latch 1303.

[0043] Before cleaning, the operating rod 701 is rotated in the opposite direction to force the valve plate 402 to move, so that the valve plate 402 closes the pipe 3. At the same time, the operating rod 701 rotates to drive the driving gear 702 to rotate, and the driving gear 702 drives the driven gear 804 to rotate, forcing the transmission rod 803 to rotate, and the transmission rod 803 drives the clamping gear 805 to rotate. Under the action of the inner gear ring 1 506 and the inner gear ring 2 802, the rotating drum 1 503 and the rotating drum 2 801 rotate, and the rotation of the rotating drum 1 503 drives the driving bevel gear 2 504 to rotate, and the rotation of the driving bevel gear drives the driven bevel gear 2 505 to rotate, so that the rotating shaft 501 rotates, forcing the filter screen 502 to rotate. When the valve plate 402 rotates to close the pipe 3, the filter screen 502 just rotates to be parallel to the central axis of the pipe 3.

[0044] When the pipeline 3 is closed, due to the impact force and pressure generated by the liquid, the solenoid valve 1008 and the one-way valve 1007 are opened, forcing the liquid to enter the liquid storage tank 1001 through the connecting pipe 1006. The liquid continuously enters the liquid storage tank 1001, forcing the liquid to drive the push piston 1002 to move, so that the push piston 1002 drives the push rod 1003 to move, forcing the push rod 1003 to drive the contact plate 1005 to contact the lower pressure rod 12010. At this time, the spring 1004 is compressed. Due to the flow of the liquid, an impact force is generated on the valve plate 402. The liquid storage tank 1001 can absorb the impact kinetic energy and reduce the impact of the liquid on the valve plate 402, thereby improving the protection of the valve plate 402. The solenoid valve 2 1102 is in a closed state, and the liquid in the liquid storage tank 1001 will not be sprayed out temporarily. When the liquid in the liquid storage tank 1001 is stored to a reasonable height, the solenoid valve 1008 and the one-way valve 1007 are closed.

[0045] The liquid in the upstream of the pipeline 3 is released, and the electromagnetic valve 3 1208 and the electromagnetic valve 4 1209 are opened, so that the liquid in the pipeline 3 is introduced into the liquid storage tank 1205 through the liquid delivery tube 1206, and the liquid in the liquid storage tank 1205 is discharged through the liquid discharge tube 1207. When part of the liquid in the pipeline 3 is discharged, the filter screen 502 is exposed, and the electromagnetic valve 4 1209 is closed at this time, forcing the remaining part of the liquid to be discharged into the liquid storage tank 1205 for storage. At this time, the liquid storage tank 120 5 gradually increases, and gravity gradually increases until the liquid in the liquid storage tank 1205 is full. At this time, the liquid in the pipe 3 is just discharged. During the gradual increase of the liquid storage tank 1205, due to the effect of gravity, the liquid storage tank 1205 exerts a gravity effect on the force plate 1203. The force plate 1203 acts on the support inner rod 1202, causing the support inner rod 1202 to move downward in the support outer rod 1201, and the spring 1204 is compressed, that is, the liquid storage tank 1205 gradually moves downward.

[0046] Open the solenoid valve 1102, the liquid storage tank 1205 drives the pressure rod 12010 to move downward, forcing the contact plate 1005 to move downward. At the same time, under the action of the spring 1004, the contact plate 1005 drives the push rod 1003 and the push piston 1002 to move downward, forcing the push piston 1002 to generate a greater force, so that a greater pressure is generated in the liquid storage tank 1001, so that the liquid in the liquid storage tank 1001 is introduced into the liquid separation plate 1103 through the cleaning conduit 1101, and the liquid is introduced into the spray head 1105 through the spray head 1105. The liquid is continuously sprayed onto the exposed filter screen 502, thereby achieving the effect of automatic flushing and cleaning of the filter screen 502 inside the pipeline 3.
