Technical Field
[0001] The utility model relates to the technical field of throttling devices, in particular to a throttling device with a resistance regulating function. Background Art
[0002] The throttling device is a flow device in which the fluid that fills the pipe flows through the pipe. The flow beam will form a local contraction at the throttling point, thereby increasing the flow velocity and reducing the static pressure. Thus, a static pressure difference is generated before and after the throttling device. The throttling flowmeter is a typical differential pressure flowmeter. It is the most commonly used flow meter used to measure the flow of gas, liquid and steam in industrial production.
[0003] At present, most of the common throttling devices on the market use orifice plates with a central opening smaller than the inner diameter of the pipe to perform throttling. Because the orifice plates are often fixedly installed, the resistance provided by the orifice plates to the liquid or gas 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.
[0004] Therefore, we propose a throttling device with resistance adjustment function. Summary of the invention

[0028] The resistance adjustment assembly 1 includes an adjustment plate 4, and the adjustment plates 4 have two adjustment plates 4. The two adjustment plates 4 are placed on the right side of the orifice plate body 17. The right side of the orifice plate body 17 is provided with two first slide grooves 5. The insides of the two first slide grooves 5 are clamped with first sliders 6. The right sides of the two first sliders 6 are fixedly connected with moving blocks 7. The two side surfaces of the two orifice plate bodies 17 are rotatably connected with connecting rods 8. The other end of each connecting rod 8 is rotatably connected to the sides of the two adjustment plates 4 that are close to each other. The rear part of the inner wall of the pipe body 3 is rotatably connected with a sealing strip 18. The front end of the sealing strip 18 penetrates the outer wall of the pipe body 3 and is rotatably connected to the outer wall of the pipe body 3. The outer surface of the positive and negative threaded rods 9 is threadedly connected with the two moving blocks 7.
[0029] A sealing strip 18 is fixedly connected between the mutually adjacent sides of the two adjustment plates 4 , so that the adjustment plates 4 can achieve a better sealing effect when sealing the orifice plate body 17 .
[0030] The front end of the forward and reverse threaded rod 9 is fixedly connected with a turntable 10, which can make it easier for the staff to rotate the forward and reverse threaded rod 9.
[0031] The threads on the outer surface of the forward and reverse threaded rod 9 are symmetrical about the center line of the forward and reverse threaded rod 9, so that the two moving blocks 7 can move synchronously in opposite directions when moving.
[0032] When it is necessary to adjust the resistance to liquid flow, the staff only needs to rotate the turntable 10 in the forward and reverse directions. When the turntable 10 is rotated in the forward direction, the forward and reverse threaded rods 9 fixedly connected to the turntable 10 can be rotated.

[0036] The second slide groove 11 and the second slider 12 are both T-shaped, which can make the adjustment plate 4 more stable when moving up and down.
[0037] When the two adjustment plates 4 move up and down, the cooperation of the second slider 12 and the second slide groove 11 can provide a guiding effect for the adjustment plate 4 when moving up and down, and further make the adjustment plate 4 more stable when moving up and down. At this time, the block 13 will move up and down inside the card groove 14.
