Description

TECHNICAL FIELD

[0001] The utility model relates to flow detection equipment technical field, concretely relates to a valve flow detection device. BACKGROUND

[0002] In industrial production and many fields related to fluid transportation and control, accurate detection of valve flow is crucial. It plays an important role in ensuring the stable operation of the system, optimizing the process, improving production efficiency, and ensuring product quality.

[0003] The existing valve flow detection device has some problems in actual application. On the one hand, the structure design of some detection devices is not reasonable, which makes the installation and maintenance of detection components not convenient. For example, the key detection components of some detection devices are installed in a position that is difficult to reach. When maintenance or replacement is needed, a lot of time and effort is spent on disassembling the entire device, which seriously affects work efficiency. On the other hand, the protection measures for detection components are insufficient. During fluid flow, impurities, particles, and other debris may impact and damage the detection components, affecting the accuracy of detection and the service life of the device. SUMMARY

[0004] Therefore, the utility model provides a valve flow detection device. When installing and maintaining the equipment, the flow is cut off by the intercepting assembly, and then the detection equipment is quickly installed and maintained through the detachable sealing cover plate and maintenance cover plate, further shortening the maintenance and installation time, avoiding affecting work efficiency, and intercepting impurities, particles, and other debris in the fluid through the arc protective net, avoiding impacting and damaging the detection components, affecting the accuracy of detection, and affecting the service life of the device.

[0005] To solve the above technical problems, the utility model provides a valve flow detection device, which comprises a fluid pipe, an inlet pipe connected to the left end of the fluid pipe, an outlet pipe connected to the right end of the fluid pipe, and a detection mechanism arranged on the fluid pipe. The detection mechanism comprises two reserved slots symmetrically arranged on the fluid pipe, a sealing cover plate sealingly connected to the opening of the reserved slot at the bottom of the fluid pipe, and a maintenance cover plate detachably connected to the opening of the reserved slot at the top of the fluid pipe. A signal transmitter is installed in the sealing cover plate through a spring support, a signal receiver is installed in the maintenance cover plate through an electric telescopic rod, and a microcomputer is arranged on the top of the maintenance cover plate for analyzing the signals received by the signal receiver. That is, by arranging the detection mechanism on the fluid pipe, the valve flow can be detected. The detachable sealing cover plate and maintenance cover plate can facilitate the quick maintenance and replacement of the internal signal transmitter and receiver, and the received signals can be analyzed and processed by the microcomputer to obtain the relevant information of the fluid pipe flow.

[0006] Each reserved slot is equipped with an arc-shaped protective net to protect the signal transmitter and receiver. This arc-shaped net prevents external debris and particles in the fluid from directly impacting the signal transmitter and receiver, reducing the risk of damage to these components due to collisions, extending their service life, improving the stability and reliability of the detection device, and ensuring continuous and stable flow detection.

[0007] Both the inlet and outlet pipes have threads machined on their inner walls, and both are equipped with sealing rings. The threads on the inner walls of the inlet and outlet pipes facilitate connection and installation with other components, improving the versatility and adaptability of the device; at the same time, the sealing rings inside enhance the sealing of the connection points, preventing fluid leakage and ensuring normal fluid flow within the device, thereby ensuring the accuracy of flow detection.

[0008] The inlet pipe is also equipped with a flow-cutting mechanism, which includes a geared motor mounted on the top of the inlet pipe and a baffle plate located inside the inlet pipe. That is, by controlling the geared motor and adjusting the position of the baffle plate inside the inlet pipe, the fluid flow can be cut off or regulated. This makes the device more suitable for scenarios requiring control of the fluid flow rate, such as when detecting valves with different flow ranges, where the flow-cutting mechanism can adjust the amount of fluid entering the detection device.

[0009] The baffle is connected to the output shaft of the geared motor via a coupling. This connection ensures that the power from the geared motor is stably and effectively transmitted to the baffle, allowing it to move accurately according to the motor's drive, thus achieving precise flow control. The coupling also buffers vibrations and impacts between the motor and the baffle to some extent, extending the service life of the components of the flow-stopping mechanism and improving the overall stability and reliability of the mechanism.

[0010] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0011] 1. A sealing cover is connected to the reserved slot opening at the bottom of the fluid pipe in the detection mechanism, and a maintenance cover is detachably connected to the reserved slot opening at the top. This allows components installed inside the sealing cover via spring brackets and components installed inside the maintenance cover via electric telescopic rods to be easily opened for maintenance when needed. Under normal circumstances, the cover remains sealed to ensure the normal operation of the device.

[0012] 2. The arc-shaped protective netting installed on each reserved slot can protect the signal transmitter and signal receiver from accidental collisions, scratches and other damage from external objects, extend their service life and ensure the stable operation of the detection device.

[0013] 3、The inner wall of the access pipe and the outlet pipe is processed with threads, and a sealing rubber ring is arranged inside. The threads enable the connection and installation with other components, and the sealing rubber ring can effectively prevent fluid leakage, ensure the sealing performance of the device during the transmission of fluid, and improve the accuracy of detection.

[0014] 4、By controlling the speed reducer, the position of the baffle can be conveniently adjusted to achieve the control of the interception or release of the fluid in the access pipe, thereby providing more flexibility and functionality for the use of the device. BRIEF DESCRIPTION OF DRAWINGS
