Description

Technical Field

[0001] This utility model relates to an adjustable guide mechanism for a rotor flowmeter, belonging to the field of flowmeters. Background Technology

[0002] Rotor flowmeter: A float that can move up and down is installed in a vertically or inclined transparent tube. When fluid passes through the transparent tube, the float is subjected to buoyancy and fluid resistance. As the fluid flow rate increases, the float rises to a position where the buoyancy and fluid resistance are balanced, thus maintaining a constant pressure difference between the upper and lower ends of the float. The higher the float's position, the greater the fluid flow rate. The float is mounted on a guide rod installed inside the transparent tube. For transparent tubes of different lengths, guide rods need to be manufactured to match the tube length. This results in guide rods being produced in different lengths, limiting their applicability. Therefore, an adjustable guiding mechanism is needed for rotor flowmeters that allows the guide rod to be installed inside transparent tubes of different lengths. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable guide mechanism for a rotor flowmeter to solve the problems mentioned in the background art. This utility model enables the guide rod to be installed in transparent cylinders of different lengths, thereby expanding the applicability of the guide rod.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable guide mechanism for a rotor flowmeter, comprising a transparent tube, both ends of which are fitted with detachable caps, and a pipe joint is installed on the side of the cap facing away from the transparent tube. Support rings are installed inside both caps, and a disc is located in the center of each support ring. Three supports are fixedly fixed in a ring at equal intervals on the annular side of the disc. The end of each support arm away from the disc is connected and fixed to the support ring. Detachable limiting tubes are installed in the center of one side of each of the two discs. A guide rod is inserted between the two limiting tubes, and a float that slides in contact with the guide rod is sleeved on the guide rod. An end cap is threadedly connected to the end of the limiting tube outside the transparent tube. An internally threaded tube is fixedly connected to the center of the end cap, and a screw is threadedly connected to the internally threaded tube. A baffle is installed at the end of the screw outside the internally threaded tube, and the baffle is slidably installed inside the limiting tube.

[0005] Furthermore, a threaded hole is provided at the center of one side of the disk, and an external thread is machined on the outer surface of the limiting tube, which is threaded into the threaded hole.

[0006] Furthermore, an internal threaded ring is installed on the side of the cylinder cover facing away from the pipe joint, and the end of the transparent tube is threaded into the internal threaded tube. The outer surface of the internal threaded ring is provided with multiple flat openings at equal intervals for engaging wrenches.

[0007] Furthermore, the pipe fitting and the cylinder cap are integrally formed, and the internal thread ring and the cylinder cap are integrally formed.

[0008] Furthermore, the outer surface of the cylinder cover is uniformly provided with a plurality of first grooves, and the outer surface of the pipe joint is uniformly provided with a plurality of second grooves.

[0009] Furthermore, the outer surface of the end cap is fixed with multiple ribs in a ring at equal intervals, and the ribs and the end cap are integrally formed.

[0010] The beneficial effects of this utility model are:

[0011] 1. Screw the threaded limiting tube into the threaded hole on the disc to facilitate the installation and removal of the limiting tube. By adjusting the relative position of the limiting tube and the disc, the length of the limiting tube extending into the transparent tube can be changed. That is, the position of the baffle in the transparent tube can be changed in the initial state, which helps to expand the limiting range of the guide rod end.

[0012] 2. Adjust the length of the screw inside the internal threaded tube, and then screw the plug onto the limiting tube. At this time, the position of the baffle inside the limiting tube changes, and the distance between the two baffles changes, so that the two ends of the guide rod are respectively inserted into the two limiting tubes. Under the restriction of the baffle, the length of the guide rod inserted into the limiting tube is limited, so that the guide rod can be installed in transparent tubes of different lengths, thus expanding the applicable range of the guide rod.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-3 This utility model provides a technical solution: an adjustable guide mechanism for a rotor flowmeter, including a transparent tube 1, both ends of which are equipped with detachable caps 2, i.e., an internal threaded ring 5 is installed on the side of the cap 2 away from the pipe connector 3, the end of the transparent tube 1 is threaded into the internal threaded tube 14, the outer surface of the internal threaded ring 5 is provided with multiple flat openings 6 for engaging wrenches in an annular shape, the side of the cap 2 away from the transparent tube 1 is equipped with a pipe connector 3, the pipe connector 3 and the cap 2 are integrally formed, the internal threaded ring 5 and the cap 2 are integrally formed, the outer surface of the cap 2 is uniformly provided with multiple first grooves, the outer surface of the pipe connector 3 is uniformly provided with multiple second grooves, the first grooves and the second grooves respectively increase the friction coefficient of the surface of the cap 2 and the surface of the pipe connector 3.

[0022] See Figures 1-4 Both cylinder caps 2 are equipped with support rings 7. A disc 12 is located in the center of the support ring 7. Three support arms 11 are fixed in a ring at equal intervals on the annular side of the disc 12. The end of the support arm 11 away from the disc 12 is connected and fixed to the support ring 7. A detachable limiting tube 10 is installed in the center of one side of each disc 12. That is, a threaded hole 13 is opened in the center of one side of the disc 12. The outer surface of the limiting tube 10 is machined with external threads. The limiting tube 10 is threaded into the threaded hole 13, so that the limiting tube 10 with external threads is screwed into the threaded hole 13 on the disc 12, which facilitates the installation and removal of the limiting tube 10. By adjusting the relative position of the limiting tube 10 and the disc 12, the length of the limiting tube 10 extending into the transparent tube 1 can be changed. That is, in the initial state, the position of the baffle 16 in the transparent tube 1 can be changed, which is beneficial to expanding the limiting range of the end of the guide rod 8.

[0023] See Figures 1-5 A guide rod 8 is inserted between the two limiting tubes 10. A float 9 is fitted onto the guide rod 8 and slides in contact with it. An end cap 4 is threaded to one end of the limiting tube 10 outside the transparent tube 1. Multiple ribs are fixed in a ring at equal intervals on the outer surface of the end cap 4. The ribs and the end cap 4 are integrally formed. The ribs increase the friction coefficient of the end cap 4 surface. An internally threaded tube 14 is fixed to the middle of the end cap 4. A screw 15 is internally threaded to the internally threaded tube 14. A baffle 1 is installed at one end of the screw 15 outside the internally threaded tube 14. 6. The baffle 16 is slidably installed inside the limiting tube 10. Adjust the length of the screw 15 inside the internal thread tube 14, and then screw the plug onto the limiting tube 10. At this time, the position of the baffle 16 inside the limiting tube 10 changes, and the distance between the two baffles 16 changes, so that the two ends of the guide rod 8 are respectively inserted into the two limiting tubes 10. Under the restriction of the baffle 16, the length of the guide rod 8 inserted into the limiting tube 10 is limited, so that the guide rod 8 can be installed in transparent tubes of different lengths, thus expanding the applicable range of the guide rod 8.
