Description

Technical Field

[0001] This utility model relates to the field of rotary flow meter technology, and in particular to a rotary flow meter with high sealing performance. Background Technology

[0002] High sealing performance describes the ability of an object to effectively prevent the entry, exit, and exchange of substances. Its core function is to effectively prevent unwanted substances from penetrating and leaking. The Roots flow meter, also known as a rotary flow meter, is a high-precision metering instrument used to continuously and intermittently measure the flow rate in pipelines.

[0003] Some rotary flow meters mainly consist of a housing, a pair of meshing rotary wheels, a transmission mechanism, and a counting display section. The working principle is to use the fluid to drive the rotary wheels to rotate, and discharge a fixed volume of fluid per rotation of the rotary wheels. The transmission mechanism then transmits the number of rotations to the counting display section, thereby realizing the measurement of fluid flow.

[0004] In existing technologies, the pipeline connection of some rotary flow meters relies on traditional flange bolt fastening and a single seal, which has the disadvantages of cumbersome installation and easy wear and failure of the seal, resulting in fluid leakage. This affects the metering accuracy and poses safety hazards. Therefore, a rotary flow meter with high sealing performance is proposed to solve the above problems. Utility Model Content

The viewing window 32 allows direct observation of the data on the display screen 4. The connecting plate 33 supports the limiting post 34, which limits the deformation position of the reset spring 35. The reset spring 35 drives the toggle block 36 to reset. The toggle block 36 is used to control the opening and closing state of the viewing window 32. The overall protection is good and the operation is convenient, ensuring the stable operation of the rotary flow meter body 1 and convenient data reading.

[0039] The implementation principle of this application embodiment is as follows: First, the sliding ring 222 compresses the telescopic spring 221, releasing the positioning ball 24. Then, the connector 25 is inserted into the connecting pipe 21, the sliding ring 222 is released, and the restoring force of the telescopic spring 221 drives the sliding ring 222 back to its initial position, and compresses the positioning ball 24 to fix the positioning component 26 between the two telescopic springs 221. The limiting ring 23 is used to limit the position of the sliding ring 222. At the same time, the two force blocks 210 compress each other, causing the sliding rod 27 to slide inside the guide ring 262, so that the sealing component 28 changes from the sealed state of the connecting pipe 21 to the open and closed state. Then, the connector 25 is tightened to the external pipe to measure the flow rate.

[0040] The protective shell 31 is used to protect the body 1 of the rotary flow meter. The data on the display screen 4 can be observed at any time through the viewing window 32. When the body 1 of the rotary flow meter needs to be repaired, the toggle block 36 is moved and the limiting post 34 is squeezed to open the viewing window 32, which makes it easy to open and close the protective shell 31.
