Description

Technical Field

[0001] This utility model belongs to the field of biomedical equipment technology, specifically a device for protecting valves from falling off. Background Technology

[0002] In the field of bio-fermentation, equipment such as fermenters, buffer storage tanks, pipelines, and filters require regular cleaning and sterilization to ensure hygienic conditions and product quality during production. CIP (Clean-In-Place) is a technology that enables automated cleaning without disassembling the equipment. SIP (Sterilize-In-Place) is an automated method that sterilizes the interior of equipment, typically using high-temperature steam or other sterilization media, without disassembling the equipment or system components. Both are widely used in the biopharmaceutical field.

[0003] In existing technologies, during CIP cleaning, the cleaning medium inside the equipment or pipeline is discharged through the inlet ports on the connecting plate. After the cleaning operation is completed, the valves need to be disassembled for subsequent processing. However, due to the weight of the valve body, improper operation during disassembly can easily cause the outer valve to fall to the ground, posing a significant safety hazard and not only the risk of valve damage but also potential injury to the operators. Utility Model Content

[0004] The purpose of this invention is to provide a device to protect valves from falling, which solves the problem that valves are prone to falling due to gravity during disassembly, posing a risk of damage or injury, thereby improving the safety and ease of operation of the disassembly and assembly process.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A device for protecting valves from falling off includes: a support column, a U-shaped flexible hose, a connecting device, a panel, an air / liquid inlet pipe, and a drain pipe;

[0007] The upper end of the support column is connected to the panel;

[0008] The air inlet pipe and the drain pipe pass through and are fixed to the panel;

[0009] The connecting device includes at least two sets. One end of the first set of connecting devices is connected to the air inlet pipe, and the other end is connected to the U-shaped hose. One end of the second set of connecting devices is connected to the U-shaped hose, and the other end is connected to the sewage pipe.

[0010] Each of the aforementioned connection devices includes a diaphragm valve and a chain for preventing the diaphragm valve from falling off during disassembly.

[0011] Furthermore, the lower end of the support column is connected to a foot plate, which is used to fix the support column to the ground.

[0012] Furthermore, the foot plate is fixed to the ground by threaded holes, screws, and nuts.

[0013] Furthermore, the number of the air inlet pipes is three or more.

[0014] Furthermore, a pipe clamp is provided at the upper end of the panel, and the U-shaped flexible hose can be suspended on the pipe clamp in the idle state.

[0015] Furthermore, each of the aforementioned connecting devices specifically includes two diaphragm valves, a quick-connect clamp, a clamp, and a clamp ear disposed on the clamp, the clamp ear being used to connect the chain.

[0016] Furthermore, the clamp is used to secure the chain to the diaphragm valve or pipe.

[0017] This utility model has the following beneficial effects:

[0018] 1. This device connects and fixes the diaphragm valve to the pipeline structure via a chain, effectively preventing the valve from accidentally falling due to gravity during disassembly, thus avoiding equipment damage or personnel injury and improving operational safety.

[0024] To make the various technical features, advantages, or effects of the present invention more apparent and understandable, detailed descriptions are provided below through embodiments.

[0025] This embodiment specifically provides a device to protect valves from falling off, such as... Figure 1 As shown, it includes: foot plate 1, support column 2, U-shaped hose 3, connecting device 4, panel 5, pipe clamp 6, air inlet pipe 7, chain 8, and drain pipe 9.

[0026] The lower end of the support column 2 is fixedly connected to the foot plate 1. The foot plate 1 is installed and fixed to the ground through threaded holes, screws and nuts. The upper end of the support column 2 is provided with a panel 5. The panel 5 is provided with a pipe clamp 6. The air inlet pipe 7 and the sewage outlet pipe 9 pass through the panel 5 in sequence and are fixedly installed on the panel 5.

[0027] The connecting device 4 includes two sets. One end of the first set of connecting device 4 is connected to the air-liquid pipe 7, and the other end is connected to the U-shaped hose 3. One end of the second set of connecting device 4 is connected to the U-shaped hose 3, and the other end is connected to the drain pipe 9, so that the air-liquid pipe 7 is connected to the drain pipe 9 through the U-shaped hose 3, forming a connecting passage.

[0028] The air inlet pipe 7 can be configured as three or more, for connecting multiple buffer storage tanks (not shown in the figure) respectively, with its other end passing through the panel 5 and connected to the connecting device.

[0029] The pipe clamp 6 is installed on the upper part of the panel 5 to suspend and fix the U-shaped hose 3 when it is not in use, so as to prevent the hose from sagging and affecting the operation.

[0030] like Figure 2 As shown, each connection device 4 includes: two diaphragm valves 41, a quick-connect clamp 42, a clamp 43, and clamp ears 44 fixed to the clamp 43. The clamp ears 44 are used to connect the chain 8, which is used to prevent the valve from falling off during disassembly; the quick-connect clamp 42 is used to quickly connect the pipeline and ensure the sealing of the connection to prevent media leakage; the clamp 43 is used to fix the chain 8 to the valve or pipeline to achieve structural constraint.

[0031] The process of using this device includes the following steps:

[0032] 1. Connecting the pipeline: Connect the outlet pipe of the buffer solution storage tank to the inlet pipe 7. After passing through the panel 5, the inlet pipe 7 is connected in series with the two diaphragm valves 41 in the first set of connecting devices 4.

[0033] 2. Connecting the U-shaped hose: Connect the first set of connecting devices 4 and the second set of connecting devices 4 through the U-shaped hose 3. The second set of connecting devices 4 also has two diaphragm valves 41 connected in series.

[0034] 3. Connect the drain pipe: Connect the outlet end of the second set of connecting devices 4 to the drain pipe 9 to form a cleaning passage;

[0035] 4. Perform cleaning operation: When performing CIP cleaning operation, open the four diaphragm valves 41 connected to both ends of the air-liquid inlet pipe 7, the drain pipe 9, and the U-shaped hose 3 at the same time, so that the cleaning liquid or gas flows sequentially through the buffer tank outlet pipe, the air-liquid inlet pipe 7, the first set of diaphragm valves 41, the U-shaped hose 3, the second set of diaphragm valves 41, and the drain pipe 9.

[0036] 5. Close valves after cleaning: After CIP cleaning is completed, close and tighten the four diaphragm valves 41 to prevent external contaminants from entering the cleaned pipeline; setting up double diaphragm valves can effectively block the risk of contamination.

[0037] 6. Dismantling and cleaning path: When production needs to be resumed, remove the U-shaped hose 3 and the four diaphragm valves 41 connected to it;

[0038] 7. Prevent valve from falling off: Since the chain 8 connects to the diaphragm valve 41, the side of the diaphragm valve 41 away from the panel 5 can be prevented from falling off accidentally during disassembly;

[0039] 8. Resumption of normal production: The diaphragm valve 41 at the end of the dismantled air-liquid pipe 7 can be connected to other production pipelines to achieve normal material output operations.

[0040] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention.
