Technical Field
[0001] This utility model relates to the field of T-type bar flow meter installation technology, specifically to a T-type bar flow meter that can be installed quickly. Background Technology
[0002] The integrated T-bar flow meter is a differential pressure flow measurement device suitable for measuring the flow of gases, liquids, and steam. It is widely used in industries such as petroleum, chemical, power, and metallurgy. It calculates the flow rate by measuring the differential pressure generated before and after the fluid in the T-bar sensor, and obtains the flow value by combining Bernoulli's equation and the fluid continuity equation.
[0003] When measuring fluids, an integrated T-type bar flow meter needs to be installed on the fluid pipeline. However, during use, it is necessary to regularly check whether the sensor and pressure tap are blocked or leaking, and the sensor needs to be cleaned regularly to keep it clean. This requires frequent maintenance or replacement. Therefore, a T-type bar flow meter that can be quickly installed on the pipeline is proposed. Utility Model Content

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-5 This utility model provides a technical solution: a quick-installation T-type bar flow meter, including a pipe 1 and a flow meter body 2. An installation connector 3 is installed on the pipe 1. The connecting end of the flow meter body 2 is connected to the installation connector 3, and a sealing gasket 4 is provided on the connecting surface. The connecting surfaces of the installation connector 3 and the connecting end of the flow meter body 2 both protrude outward to form bosses 5, and the opposing surfaces of the two bosses 5 are inclined. After the two bosses 5 are connected, a retaining ring 6 and a retaining ring 7 are fastened on the outside. The retaining ring 6 and the retaining ring 7 are arranged opposite to each other. A tensioning component 8 is installed on the retaining ring 6, and a tensioning rope 9 is detachably installed on the retaining ring 7. By adjusting the tensioning component 8, the tensioning rope 9 wrapped around the tensioning component 8 is tightened, so that the retaining ring 6 and the retaining ring 7 move closer to each other, and the distance between the two bosses 5 is adjusted.
[0021] The first retaining ring 6 and the second retaining ring 7 are arc-shaped buckle plates, with an arc angle preferably between 120-180°. The tensioning component 8 is installed at the middle of the arc-shaped outer end of the first retaining ring 6.
[0022] The connection end of the flow meter body 2 and the mating surface of the mounting connector 3 are both provided with a storage groove 10 for storing the sealing gasket 4.
[0023] The inner end shapes of the retaining ring 6 and retaining ring 7 match the surface shape of the boss 5.
[0024] Both ends of the second retaining ring 7 are equipped with symmetrical hooks 11, and both ends of the tension rope 9 are equipped with mounting posts 12, which are hooked onto the hooks 11 on the same side respectively.
[0025] The side of the retaining ring 6 has a limiting groove 13 for limiting the position of the pull hook 11.
[0026] The tensioning assembly 8 includes a mounting block 81, which is mounted on the outer end of the retaining ring 6. A slider 82 is slidably mounted on the mounting block 81, and a rotating wheel 83 is rotatably mounted on the slider 82. The tensioning rope 9 is wound around the recess on the surface of the rotating wheel 83. A screw 84 is rotatably mounted on the end of the slider 82, and the screw 84 is screwed to the mounting block 81.
[0027] The mounting block has a groove, and the slider is slidably disposed in the groove. Positioning blocks are installed on both the upper and lower surfaces of the slider corresponding to the groove on the mounting block to reduce the tilting of the slider during movement.
[0028] The end of the mounting block 81 extends laterally to form a limiting part 85. The limiting part 85 has an opening 86 for receiving the shaft of the rotating wheel 83. After the tension rope 9 is tightened, the part of the tension rope 9 wrapped around the rotating wheel 83 is between the limiting part 85 and the mounting block 81, thus limiting the tension rope 9.
[0029] Working principle: First, place the sealing gasket 4 into the receiving groove 10 on the mounting joint 3. Then, connect the connecting end of the flowmeter body 2 to the mounting joint 3 and align them so that the sealing gasket 4 is located in both receiving grooves 10. Next, fasten the retaining ring 6 onto the two mating bosses 5. Then, fasten the retaining ring 7 onto the two mating bosses 5 opposite to the retaining ring 6. Hook the mounting posts 12 at both ends of the tension rope 9 onto the hooks 11 on both sides of the retaining ring 6. Then, wrap the tension rope 9 around the recess of the rotating wheel 83 and pre-tighten it. The screw 84 moves, which in turn moves the slider 82. The slider 82 then moves the rotating wheel 83, gradually tightening the tension rope 9. During the tightening process, the retaining ring 6 and the retaining ring 7 act simultaneously on the boss 5. The inclined surfaces inside the retaining ring push the two bosses 5 closer together, compressing the sealing gasket 4 and sealing the connection end of the flowmeter body 2 with the mounting joint 1. This completes the installation of the flowmeter body 2. When disassembling, simply turn the screw 84 in the opposite direction to loosen the taut tension rope 84, and the flowmeter body 2 can be disassembled.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
