Description

Technical Field

[0001] This utility model relates to the field of throttling device technology, specifically a throttling device with resistance adjustment function. Background Technology

[0002] A throttling device is a device used to measure and control fluid flow rate. It generates a pressure difference by changing the cross-sectional area of ​​the fluid channel, thereby achieving the regulation and measurement of flow rate.

[0003] A search revealed existing technologies, such as the throttling device in announcement number CN219120082U, which includes an instrument tube and a throttling element. The instrument tube has a flow channel, and the inner wall of the flow channel has a mounting protrusion along its circumference. The instrument tube has a first pressure tap and a second pressure tap on both sides of the mounting protrusion, respectively, and both are connected to the flow channel. The throttling element is a plate-like structure, detachably fixed to the mounting protrusion and sealed to the instrument tube. The throttling element has a throttling orifice. Because the throttling element is detachably fixed to the instrument tube, it can be quickly replaced when excessive wear occurs during long-term use. This solves the problem that when the throttling element is integrally mounted on the instrument tube, replacement requires returning it to the manufacturer for calibration and repair, which is extremely inconvenient in terms of time and economy.

[0004] In summary, existing throttling devices allow for quick replacement of the throttling element, but the resistance provided by the orifice plate of existing throttling devices to liquids or gases is often fixed. When the resistance of the throttling device needs to be adjusted, the orifice plate needs to be replaced, which is time-consuming and labor-intensive. Therefore, a throttling device with resistance adjustment function is proposed. Utility Model Content

[0011] Preferably, a positioning ring is fixedly installed on the inner wall of the tube, and a filter screen mechanism is detachably installed on one side of the positioning ring.

[0012] The above technical solution facilitates the later maintenance of the filter screen mechanism.

[0013] Preferably, the filter mechanism includes a mounting ring frame, and a filter screen is fixedly mounted on the inner side of the mounting ring frame.

[0014] The above technical solution facilitates the later maintenance of the filter screen mechanism.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This throttling device with resistance adjustment function solves the problem that the resistance provided by the orifice plate of existing throttling devices to liquids or gases is often fixed, and the orifice plate needs to be replaced when the resistance of the throttling device needs to be adjusted.

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.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a throttling device with resistance adjustment function, wherein a fixed plate 2 is fixedly installed inside the tube body 1, and the fixed plate 2 is provided with a number of discharge holes 201.

[0026] Specifically, the outer side of the pipe body 1 is provided with an anti-corrosion layer 3, which includes a boron nitride coating layer 301, a polyimide coating layer 302, and a zinc silicate coating layer 303.

[0027] In a further embodiment, a boron nitride coating layer 301 is fixedly disposed on the outside of a polyimide coating layer 302, and a polyimide coating layer 302 is fixedly disposed on the outside of a zinc silicate coating layer 303. The boron nitride coating layer 301 has a very low coefficient of friction, excellent high-temperature stability, excellent thermal shock resistance, high strength, high thermal conductivity, antistatic properties, and corrosion resistance. The polyimide coating layer 302 has good insulation properties, good heat resistance, high tensile strength, resistance to organic solvents, ozone, mildew resistance, and good corrosion resistance. The zinc silicate coating layer 303 has good durability, good self-sealing properties, and excellent corrosion resistance, high-temperature resistance, weather resistance, and UV aging resistance. Through the combination of the above structures, the advantage of good corrosion resistance on the outside of the pipe body 1 is achieved.

[0028] Specifically, a positioning ring 4 is fixedly installed on the inner wall of the pipe body 1, and a filter screen mechanism 5 is detachably installed on one side of the positioning ring 4. The filter screen mechanism 5 includes a mounting ring frame 501, and a filter screen 502 is fixedly installed on the inner side of the mounting ring frame 501. The above arrangement facilitates the replacement and maintenance of the filter screen mechanism 5 in the future. By setting the filter screen mechanism 5, impurities in the conveying process can be filtered, reducing the possibility of blockage.

[0029] Specifically, a rotating disk 202 is rotatably connected to one side of the fixed disk 2, and the rotating disk 202 has several sets of moving holes 203 that match the discharge hole 201. A ring rack 204 is fixedly installed on the outside of the rotating disk 202, and the ring rack 204 meshes with the first gear 205. The first gear 205 is installed on the outside of the first rotating rod 206, and the first rotating rod 206 is rotatably connected to the inside of the mounting box 207. The first gear 205 meshes with the second gear 208, and the second gear 208 is installed on the outside of the second rotating rod 209.

[0030] In a further embodiment, the second gear 208 is smaller than the first gear 205, and when the second gear 208 rotates, it can drive the first gear 205 to rotate at a reduced speed.

[0031] To further explain, the tube body 1 and the mounting box 207 are provided with a rotating through groove that cooperates with the first gear 205.

[0032] When resistance adjustment is required, the drive motor 2093 is turned on.

Under the action of the rotation of the second rotating rod 209, the first gear 205 is driven to rotate through the second gear 208. Under the action of the rotation of the first gear 205, the rotating disk 202 and the moving hole 203 are driven to rotate and move through the ring rack 204. The movement of the moving hole 203 changes the overlap flow gap between it and the discharge hole 201, thereby changing the flow resistance.
