Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a novel liquid flow indicator. Background Art

[0002] A flow indicator is a device used to monitor and display the flow status of a fluid in a pipeline or other closed system. It is usually installed on the fluid transmission line and can provide an instant visual or electronic signal to indicate whether the fluid is flowing, as well as the speed or amount of flow. Flow indicators come in many forms, including mechanical wheels or floats, as well as advanced versions that use electronic sensors. These devices not only help monitor fluid flow in real time, but also trigger alarms when fluid flow is abnormal. They are an indispensable component of many industrial and experimental systems.

[0003] When applying for the present invention, the applicant found through search that a Chinese patent disclosed a "visual flow indicator" with the application number "CN202321247746.3". The patent mainly adopts a main body mechanism, a protective mechanism and a dredging mechanism. The protective mechanism is located inside the main body mechanism, and the dredging mechanism is located on the side inside the main body mechanism. The dredging mechanism includes a support block, a limit rod, a retaining spring, a scraper, a limit hole and a latex brush. The limit rod is fixedly installed at the middle part of the inner end of the support block, the retaining spring is fixedly installed at the rear side of the inner end of the limit rod and is located on the outside of the limit rod, and the scraper is fixedly installed at the outer end of the retaining spring and is movably connected to the limit rod.

[0004] However, the structural design of the vibration indicator of the device is not conducive to opening and maintenance. In actual use, this design is particularly prominent in compact or inaccessible installation locations, making it extremely difficult to perform regular maintenance or troubleshooting when problems occur. This not only increases maintenance costs, but may also cause more serious equipment failures due to untimely maintenance; secondly, the flow indicator has limitations in providing information about the state of the fluid. It lacks intuitive indicator lights and cannot provide timely and direct fluid status; therefore, the operator can often only rely on checking the glass cover on the equipment to indirectly observe the flow of the fluid. This method not only relies on manual observation, but also greatly reduces accuracy and timeliness. This visual inspection method significantly increases the complexity of the operation and may lead to delays in important information when the fluid flow state changes rapidly.

[0005] To this end, we propose a new type of liquid flow indicator. Utility Model Content

[0006] The utility model provides a novel liquid flow indicator, which can be easily maintained and inspected, and the flow state of the fluid can be observed in real time.

[0007] To achieve the above-mentioned purpose, a new type of liquid flow indicator is provided, which includes a valve body, a screw hole is provided at the top of the valve body, a bolt is threadedly connected to the inner wall of the screw hole, a pull ring is installed above the bolt, a pressure cap is threadedly connected to the outer surface of the bolt, a glass cover is fixedly connected to the inner wall of the pressure cap, a connecting piece is fixedly connected to the outer surface of the valve body and the pressure cap away from the bolt, a plurality of screw holes are provided on the side of the connecting piece away from the valve body, a hinge is threadedly connected to the screw hole, a generator is installed at the bottom end of the valve body, a shaft is fixedly connected to the output end of the generator, an impeller is installed on the outer surface of the shaft, a plurality of blades are fixedly connected to the outer surface of the impeller, a rectifier is provided on the outer surface of the valve body away from the connecting piece, an indicator light base is threadedly connected to the top of the rectifier, and an indicator light is fixedly connected to the top of the indicator light base.

[0008] According to the novel liquid flow indicator, a screw hole corresponding to and having the same size as the screw hole at the top end of the valve body is provided on the outer surface of the gland, and the diameter of the screw hole is consistent with the diameter of the bolt.

[0009] According to the novel liquid flow indicator, a through hole is formed above the bolt, and a pull ring is movably connected inside the through hole.

[0010] According to the novel liquid flow indicator, the diameter of the through hole is consistent with the diameter of the pull ring, and the pull ring can rotate around the through hole.

[0011] According to the novel liquid flow indicator, a circular sealing groove is provided inside the gland, a sealing ring is installed inside the sealing groove, and the size of the sealing ring is consistent with that of the sealing groove.

[0012] According to the novel liquid flow indicator, a plurality of screw holes are provided at the top of the rectifier, and a plurality of screw holes are provided on the outer surface of the indicator light base. The screw holes at the top of the rectifier correspond to the screw holes at the outer surface of the indicator light base.

[0013] According to the novel liquid flow indicator, the blades are evenly distributed along the outer surface of the impeller, and the blades are in a curved shape.

[0014] The beneficial effects of the utility model are as follows: the valve body and the bolts ensure that the valve body and the gland are more firmly fixed, the bolts are designed for quick disassembly and assembly, the bolts can be easily operated through the pull ring, and maintenance and inspection are more convenient, the movable connection design of the pull ring allows it to rotate around the perforation, which provides flexibility for operation, especially in the case of narrow space or inconvenient direct manual operation, the glass cover allows the operator to directly observe the flow state of the fluid, provides the possibility of visual monitoring, and increases the transparency and controllability of equipment operation, and the combined use of the connector and the hinge provides additional mechanical support and flexibility, so that the valve body and the gland can be more easily adjusted or replaced, especially in the case of frequent maintenance or inspection. In application scenarios, the evenly distributed curved blades on the impeller can effectively rotate and drive the generator to generate electricity. This design not only improves the energy utilization efficiency, but also may provide necessary power support for the device itself or peripheral equipment. The combination of the rectifier and the indicator light provides a visual indication function, which is essential for monitoring and controlling the fluid flow state. The indicator light allows the operator to instantly obtain feedback on the fluid flow state, such as indicating different operating conditions or warning messages through different colors or flashing frequencies. The circular sealing groove designed inside the gland and its matching sealing ring ensure good sealing with the valve body, effectively preventing fluid leakage and improving the overall safety and reliability of the system.

A rectifier 5 is provided on the outer surface of the valve body 1 away from the connecting piece 10. The top of the rectifier 5 is threadedly connected to an indicator light base 7, and the top of the indicator light base 7 is fixedly connected to an indicator light 4. The valve body 1 is made of corrosion-resistant stainless steel to cope with the flow of various chemical media and ensure durability under long-term use. The glass cover 3 is made of tempered glass or high borosilicate glass. Such materials are not only highly transparent, but also can withstand higher pressure and impact to ensure safe observation.

[0025] The outer surface of the gland 2 is provided with a screw hole which corresponds to the screw hole at the top end of the valve body 1 and has the same size as that of the screw hole, and the diameter of the screw hole is consistent with the diameter of the bolt 8 .

[0026] A through hole is opened above the bolt 8, and a pull ring 9 is movably connected inside the through hole. The through hole is designed on the bolt 8 and the pull ring 9 is movably connected through the hole, so that the operator can more conveniently rotate the bolt 8 through the pull ring, especially providing additional mechanical advantage when tightening or loosening the bolt 8. The existence of the pull ring 9 greatly improves the convenience and efficiency of user operation.

[0027] The diameter of the perforation is consistent with the diameter of the pull ring 9, and the pull ring 9 can rotate around the perforation. The consistency of the perforation diameter and the pull ring 9 diameter not only ensures the smooth movement of the pull ring 9, but also prevents friction and wear during operation. Proper cooperation can extend the service life of the components and maintain smooth operation.

[0028] A circular sealing groove is provided inside the gland 2, and a sealing ring is installed inside the sealing groove. The sealing ring has the same size as the sealing groove. The sealing ring installed inside the sealing groove provides an additional layer of leakage protection, which is particularly important for systems containing dangerous or expensive fluids. The sealing ring is made of a material resistant to chemical corrosion and high temperature, such as fluororubber, to ensure good sealing performance in various environments.

[0029] A plurality of screw holes are provided at the top of the rectifier 5, and a plurality of screw holes are provided on the outer surface of the indicator light base 7. The screw holes at the top of the rectifier 5 correspond to the screw holes on the outer surface of the indicator light base 7. The screw hole design on the rectifier 5 and the indicator light base 7 ensures precise docking and fixation between the two. This design facilitates the installation and maintenance of the indicator light 4.

[0030] The blades 14 are evenly distributed along the outer surface of the impeller 13 and have a curved shape. The blades 14 are evenly distributed along the outer surface of the impeller 13 and have a curved shape, which helps to optimize the fluid dynamics and reduce turbulence and resistance generated during fluid flow. The curved blades 14 can more effectively capture flow energy and improve the efficiency of the entire generator set.

[0031] Working principle: When maintenance is required, it is achieved by operating the bolt 8. A pull ring 9 is provided on the top of the bolt 8 for the convenience of the operator to grab. The pull ring 9 is designed as a movable connection and can rotate freely around the perforation, which facilitates the rotation of the bolt 8, especially in an environment with compact space or difficult to operate directly by hand. By rotating the pull ring 9, the bolt 8 is screwed out of the screw hole, thereby loosening the gland 2. Once the gland 2 is loosened, it can be lifted from the top of the valve body 1 by rotating the hinge 11. When the fluid passes through the valve body 1, it flows through the impeller 13. The evenly distributed curved blades 14 on the impeller 13 capture the power of the fluid and convert it into rotational power. The impeller 13 is connected to the shaft 12 of the generator. When the impeller 13 is driven and rotated by the fluid, it synchronously drives the internal mechanical structure of the generator 6 through the physically connected shaft 12, so that the generator 6 starts to generate electricity. This method of power generation is similar to the working principle of a water turbine or a wind turbine, that is, through the fluid Power is directly converted into mechanical energy, and then into electrical energy. The electricity generated by the generator 6 is first alternating current AC. In order to convert this alternating current into direct current DC that can be used by the equipment, it must undergo a rectification process. The rectifier 5 is installed on the outer surface of the valve body. Its function is to convert the alternating current from the generator 6 into direct current. The rectifier 5 usually contains diodes or bridge rectifier components. These components allow current to flow in only one direction, thereby realizing the conversion from AC to DC. The rectified power is more suitable for powering electronic devices, such as the indicator light 4, because most low-power electronic devices require a stable DC power supply to ensure normal operation. The indicator light 4 is installed on the indicator light base 7 at the top of the rectifier 5. The DC power rectified by the rectifier 5 is used to power the indicator light 4, which enables the indicator light 4 to display different signals according to the operating status of the equipment, such as indicating the normality, warning or fault status of the fluid flow through different colors or flashing frequencies.

[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
