Technical Field
[0001] This utility model relates to the field of liquid flow monitoring and control technology, specifically to a liquid flow monitoring and control device. Background Technology
[0002] Liquid flow monitoring and control devices, also known as liquid flow detection and control valves, are automated valve devices that integrate flow detection and flow regulation. They can monitor the liquid flow in pipelines in real time and automatically adjust the opening according to the set value to maintain precise flow control. They are widely used in industrial automation, water treatment, chemical, and pharmaceutical fields to achieve intelligent flow management.
[0003] When using a liquid flow monitoring and control device, the pipes connected at both ends are sealed at the end face through sealing gaskets. However, during long-term use, the sealing gaskets will age. At this time, gaps are easily generated at the connection end between the external pipe and the liquid flow monitoring and control device, which will cause leakage and bring great inconvenience to the normal use of the device.
[0004] In summary, existing liquid flow monitoring and control devices suffer from the problem that the internal sealing gaskets can age, leading to gaps at the connection between the external pipeline and the liquid flow monitoring and control device, and causing leakage. Utility Model Content
[0005] The purpose of this utility model is to provide a liquid flow monitoring and control device to solve the technical problem that in most existing liquid flow monitoring and control devices, the internal sealing gaskets will age during long-term use, resulting in gaps at the connection between the external pipeline and the liquid flow monitoring and control device, causing leakage.
[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:
[0007] A liquid flow monitoring and control device,
[0008] The device includes a control valve body, with connecting pipes at both ends of the control valve body, and matching adapter pipes at both ends of the connecting pipes, with a sealing component for sealing inside the adapter pipe.
[0009] The sealing assembly includes an outer peripheral airbag sleeve disposed on the inner wall of the connecting pipe, a retaining ring disposed around the inner wall of the connecting pipe, an airbag gasket disposed on the side of the retaining ring near the adapter pipe, a support ring plate disposed on the side of the airbag gasket near the adapter pipe, a sealing gasket disposed on one side of the support ring plate for forming a seal on the end of the adapter pipe, and a manifold air passage opened on the inner wall of the connecting pipe for connecting the outer peripheral airbag sleeve and the airbag gasket.
[0010] Preferably, the internal components of the control valve body include a flow sensor, a control valve body, an electric actuator, a controller, and a communication module.
[0011] Preferably, pipe fittings are provided at both ends of the adapter pipe.
[0012] Preferably, the side wall of the control valve body is provided with a signal terminal for power supply and signal transmission.

[0015] Preferably, the airbag pad is provided with a compensating spring for supporting the support ring plate.
[0016] Preferably, the outer wall of the connecting pipe is provided with a one-way valve pipe that communicates with the outer peripheral airbag sleeve.
[0017] Preferably, the port of the one-way valve tube is movably provided with a threaded sealing plug.
[0018] Preferably, both the outer airbag sleeve and the airbag pad are made of elastic silicone.
[0019] The beneficial effects of this utility model are:
[0020] 1. In this utility model, the outer circumferential airbag sleeve provides elastic support to the sealing ring sleeve, allowing the sealing ring sleeve to fit tightly against the outer wall of the adapter tube and form a seal on the outer wall of the adapter tube. The airbag gasket and the compensating spring provide elastic support to the support ring plate and the sealing gasket, allowing the sealing gasket to form a good seal on the end of the adapter tube. The double seal formed by the two can provide a good seal on the adapter tube. Furthermore, the elastic support structure can compensate for the aging of the sealing ring sleeve or the sealing gasket, thereby greatly reducing the probability of leakage in the device and ensuring the reliability and safety of the device.
[0021] 2. In this utility model, the outer peripheral airbag sleeve and the airbag gasket are connected through a manifold. The one-way valve tube is used to inflate or deflate the outer peripheral airbag sleeve, thereby adjusting the inflation volume inside the outer peripheral airbag sleeve and the airbag gasket.

Detailed Implementation
[0028] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0029] like Figure 1-4 As shown, a liquid flow monitoring and control device,
[0030] The device includes a control valve body 1, with connecting pipes 2 at both ends of the control valve body 1, and adapter pipes 3 at both ends of the connecting pipes 2. The adapter pipes 3 have sealing components inside for sealing, and pipe fittings 4 are provided at both ends of the adapter pipes 3. The liquid flow monitoring and control device is mainly composed of the control valve body 1 as the core component, which integrates flow monitoring, flow control and communication functions to achieve precise control and remote management of liquid flow. The adapter pipes 3 are used to connect to external pipe fittings 4, and the connection between the pipe and the connecting pipe 2 is achieved through the adapter pipes 3 to realize the flow of liquid in the pipeline system.
[0031] The sealing assembly includes an outer peripheral airbag sleeve 7 disposed on the inner wall of the connecting pipe 2, an embedded annular groove 6 for installing the outer peripheral airbag sleeve 7 on the inner wall of the connecting pipe 2, a sealing ring 8 for forming radial density on the outer surface of the adapter pipe 3 on the inner wall of the outer peripheral airbag sleeve 7, a retaining ring 9 surrounding the inner wall of the connecting pipe 2, an airbag gasket 10 disposed on the side of the retaining ring 9 near the adapter pipe 3, a support ring plate 11 disposed on the side of the airbag gasket 10 near the adapter pipe 3, a sealing gasket 12 disposed on one side of the support ring plate 11 for forming a seal on the end of the adapter pipe 3, and a connection between the outer peripheral airbag sleeve 7 and the airbag gasket on the inner wall of the connecting pipe 2. The air passage 14 of the airbag 10 has a compensating spring 13 inside to support the support ring plate 11. The outer wall of the connecting pipe 2 is provided with a one-way valve pipe 15 that communicates with the outer peripheral airbag sleeve 7. The port of the one-way valve pipe 15 is movably provided with a threaded sealing plug 16. The outer peripheral airbag sleeve 7 and the airbag gasket 10 are connected to each other through the air passage 14. When the adapter pipe 3 is installed inside the connecting pipe 2, the end of the adapter pipe 3 will squeeze the sealing gasket 12 and the support ring plate 11. At this time, the airbag gasket 10 collapses, the compensating spring 13 deforms and is compressed, and the sealing gasket 12 presses against the adapter pipe. A good seal is formed at the end of 3. When the airbag gasket 10 collapses, the gas inside it enters the outer peripheral airbag sleeve 7 through the manifold 14. The outer peripheral airbag sleeve 7 expands, and the expanded outer peripheral airbag sleeve 7 causes the sealing ring 8 to fit tightly against the outer wall of the adapter tube 3, thus forming a seal between the sealing ring 8 and the outer wall of the adapter tube 3. Therefore, the two work together to form a double seal for the adapter tube 3, greatly reducing the probability of leakage during later use and effectively preventing liquid leakage from the connection between the adapter tube 3 and the connecting tube 2. The retaining ring 9 provides installation positioning for the airbag gasket 10, ensuring the stability of the airbag gasket 10 during use. Qualitatively, the airbag gasket 10 and the compensating spring 13 provide elastic force to ensure that the sealing gasket 12 and the end of the adapter tube 3 are in close contact, thus achieving end sealing. The one-way valve tube 15 is used to inflate or deflate the outer peripheral airbag sleeve 7, thereby adjusting the inflation amount inside the outer peripheral airbag sleeve 7 and the airbag gasket 10, thereby controlling the tightness of the contact between the sealing ring sleeve 8 and the sealing gasket 12 and the adapter tube 3. The sealing degree of the sealing ring sleeve 8 and the sealing gasket 12 can be flexibly adjusted to adapt to different installation and use requirements. The sealing plug 16 forms a seal on the one-way valve tube 15, which is used to seal the one-way valve tube 15 after inflation or deflation to prevent gas leakage.
[0032] In this embodiment, specifically, the control valve body 1 is internally equipped with a flow sensor, a control valve body, an electric actuator, a controller, and a communication module. The flow sensor is used to detect the liquid flow rate and velocity, the control valve body is used to regulate the flow rate, and the electric actuator is used to drive the valve core. The controller is used to process sensor data, calculate regulation commands (PID algorithm), and support manual / automatic mode switching. The communication module is used to transmit flow data and valve status to the host system.
[0033] In this embodiment, specifically, the side wall of the control valve body 1 is provided with a signal terminal 5 for power supply and signal transmission. The signal terminal 5 provides power support and data transmission channel for the device.
[0034] In this embodiment, specifically, both the outer airbag sleeve 7 and the airbag pad 10 are made of elastic silicone material, which has good elasticity and sealing properties, and can adapt to different pressure and temperature conditions to ensure sealing effect.
[0035] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0036] The working principle of this utility model is as follows: When the device is in use, the adapter tube 3 is first connected to the external pipe fitting 4, and then the adapter tube 3 is connected to the connecting pipes 2 at both ends of the control valve body 1. The one-way valve tube 15 inflates the outer peripheral airbag sleeve 7. The gas enters the airbag gasket 10 through the manifold 14, causing the outer peripheral airbag sleeve 7 and the airbag gasket 10 to expand. The sealing ring 8 on the inner wall of the outer peripheral airbag sleeve 7 forms a radial seal on the outer surface of the adapter tube 3. The sealing gasket 12 on the airbag gasket 10 is in close contact with the end of the adapter tube 3 to form an end seal. At this time, a good sealing effect is formed. After inflation is completed, the one-way valve tube 15 is sealed with the sealing plug 16. Then the device is powered on, and the flow sensor monitors and controls the liquid flow in real time.
[0037] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
