Embodiment Construction
[0023] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0024] combine Figure 1-8 , the main structure of the rotary plate throttling resistance regulator includes a flange connection hole 1, an annular flange 2, a main body shell 3, an opening adjustment handle 4, an opening adjustment connecting rod 5, a fluid sealing box 6, and a dynamic and static baffle 7 , Sealed bearing 8 and opening adjustment groove 9.
[0025] The rotary plate throttling resistance adjuster is connected to the main channel through a flange; the throttling baffle 7 is composed of a stationary baffle 7a and a rotatable baffle 7b, both of which are fan-shaped. Petal structure, the number of petals is the same and all are thin plate structures to reduce the overall weight of the regulator, such as figure 1 and figure 2 show; combine image 3 , Figure 4 and Figure 5 , the stationary baffle 7a is consolidated with the main body shell 3, a...

The invention provides a rotary plate type throttling resistance regulator. The rotary plate type throttling resistance regulator comprises a main body shell, movable and fixed baffles and an opening degree regulating device, wherein the movable and fixed baffles comprise a fixed baffle and a rotatable baffle, the fixed baffle and the rotatable baffle are respectively of a fan-shaped and sectioning structure, the center of the fixed baffle and the center of the rotatable baffle are installed together through a sealing bearing, both ends of the fixed baffle are fixed to the inner wall of the main body shell, the rotatable baffle can rotate around the center of the rotatable baffle, the opening degree regulating device comprises an opening degree regulating connecting rod, an opening degree regulating groove is formed in the main body shell, the opening degree regulating connecting rod is installed in the opening degree regulating groove and is connected with the rotatable baffle, an opening degree regulating handle is installed at the end of the opening degree regulating connecting rod, and the rotating angle of the rotatable baffle can be controlled by controlling the opening degree regulating handle. According to the rotary plate type throttling resistance regulator, the defect that a large thickness is needed is overcome through the cooperation between the rotatable baffle and the movable baffle, complicated transmission mechanisms such as a driving motor and a gear rack are not adopted by an opening degree regulating mechanism, and the field operation serving effect is improved.
Description
technical field [0001] The invention relates to a throttling device. Background technique [0002] In production practice and experimental research, it is often necessary to use simplified devices to simulate the resistance of fluid flow under long pipelines or other complex piping conditions. The throttling resistance adjustment device meets the above requirements by changing the throttling section or throttling length, and Realize the simulation and adjustment of fluid flow resistance. In order to improve the throttling effect and meet the resistance adjustment requirements under specific conditions, many companies and research institutions at home and abroad are committed to the optimal design of resistance adjustment devices. [0003] In foreign countries, Cameron, a manufacturer of oil and natural gas pressure control equipment, improved the cylindrical throttling plate into a misalignment method of two disc rotating holes, which improved the throttling effect. EEC co...
