[0003] The glass rotor flowmeter has a simple structure, mainly consisting of a vertical glass or transparent plastic tube and a float that can move up and down. Flanges for fixing the connection with the pipeline are fixed at both ends of the glass tube for corresponding pipeline connection.

[0004] In actual operation, when the flow meter needs to be fixed, the flange on the flow meter needs to be aligned with the corresponding pipe, and then the flange needs to be fixedly connected to the flange on the corresponding pipe with bolts. When the distance between the two pipes is large or small, the pipes need to be constantly adjusted, making the flow meter more troublesome to install and fix. Utility Model Content

[0008] By adopting the above technical solution, the two ends of the support shell are facing the pipes to be installed, and then the support installation mechanism is used to simultaneously abut against the corresponding pipes, and then the support shell is rotated to make the support installation mechanism tightly abut against the pipe, so that the flow meter can be fixed on the corresponding pipe more conveniently, reducing the tediousness and trouble of installation and fixation.

[0017] Furthermore, two symmetrical auxiliary rotating rods are fixed to one end of the supporting shell.

[0018] By adopting the above technical solution, two symmetrical auxiliary rotating rods are fixed on the supporting shell, and the auxiliary rods are located at the lower end of the supporting shell, so that the front and back of the supporting shell can be easily identified and the supporting shell can be easily rotated.

Then, the support shell is rotated again, so that the support shell drives the support ring, and the support ring drives the corresponding first conflicting threaded sleeve, so that the two second conflicting threaded sleeves are further close to the pipe. While approaching, the conflicting ring is guided by the trumpet-shaped conflicting sleeve to align the conflicting ring with the pipe, and then the conflicting sealing ring on the conflicting ring conflicts with the corresponding pipe, so as to complete the support and fixation of the support shell, and the two pipes pass through the corresponding first and second conflicting threaded sleeves, and then communicate with the glass pipe, so as to achieve the purpose of conveniently fixing the support shell between the two pipes and reducing the possibility of adjusting the distance between the two pipes back and forth when fixing.

By installing the support and installation mechanism 5 on the support shell 1, when installing and fixing, directly let the support and installation mechanism 5 abut against the corresponding pipe for squeezing and fixing, so that the flowmeter can be more conveniently fixed on the corresponding pipe, reducing the tediousness and trouble of installation and fixing.

[0039] First, place the support shell 1 between the two pipes, and then rotate the second conflicting threaded sleeve 532 according to the distance between the two pipes, so that the second conflicting threaded sleeve 532 drives the conflicting ring 52 to approach the pipe, and the conflicting ring 52 contacts the corresponding pipe, and then rotate the support shell 1, so that the support shell 1 drives the support ring 51, and the support ring 51 drives the corresponding conflicting threaded sleeve 1 531, so that the two conflicting threaded sleeves 532 are further close to the pipe, and at the same time, the trumpet-shaped conflicting sleeve 54 is used to guide the conflicting ring 52, so that the conflicting ring 52 is aligned with the pipe, and then The contact sealing ring on the contact ring 52 is allowed to contact the corresponding pipe to complete the support and fixation of the support shell 1, and the two pipes are allowed to pass through the corresponding contact threaded sleeve 1 531 and the contact threaded sleeve 2 532, and then connected with the glass tube 2, and the contact threaded sleeve 2 532 is allowed to rotate on the contact threaded sleeve 2 532 to make the support ring 51 and the contact ring 52 approach or move away from each other, and the contact ring 52 is allowed to contact the corresponding pipe, so that the support shell 1 can be conveniently fixed between the two pipes, reducing the possibility of adjusting the distance between the two pipes back and forth when fixing.
