Abstract

This utility model discloses a throttling orifice plate and a throttling pipe, specifically relating to the field of throttling orifice plate technology. It includes multiple sets of flow-slowing components for throttling and buffering; each set of flow-slowing components includes a flow-slowing plate with a funnel-shaped cross-section. Multiple throttling orifices are evenly spaced within the flow-slowing plate. A spiral flow-slowing element for turbulence is installed inside the concave surface of the flow-slowing plate, and the spiral flow-slowing element has a spiral cross-section. This utility model guides the water flow spirally through the spiral flow-slowing element, achieving the effect of dispersing and diverting the water and creating mutual turbulence and impact. The multiple throttling orifices on the flow-slowing plate then further slow down and divert the water. Subsequently, a first and a second mesh plate gradually disperse the water after the secondary slowing and diversion, causing the water flow to gradually become calm. This achieves a multi-stage impact mitigation effect, thereby enhancing the throttling effect of this utility model.

Description

Technical Field

[0001] The utility model relates to the technical field of throttling orifice plates, in particular to a throttling orifice plate and a throttling tube. Background Art

[0002] When the pressure difference before and after the pipeline is large, the method of adding a throttling orifice plate is often adopted. The principle is: when the fluid flows in the pipeline, the local resistance of the orifice plate causes the pressure of the fluid to decrease and energy is lost. This phenomenon is called throttling in thermodynamics.

[0003] As shown in the application document with the prior art publication number CN218564727U, it includes a plate body, a throttling hole is provided on the plate body, there are multiple throttling holes, all the throttling holes are evenly distributed in a circle, the outlet ends of all the throttling holes are inclined toward the axial direction of the plate body, and the axes of all the throttling holes intersect with the axis of the plate body at one point. The decompression throttling device includes the above-mentioned throttling hole plate. The decompression throttling device has good throttling effect and cavitation resistance, and low noise.

[0004] However, when the water flow in the above technical solution directly hits the throttling hole, the throttling hole has a small diameter, resulting in a large pressure when the water flows out, which in turn affects the throttling effect of the technical solution, and each set of plates can only slow down the water flow once, resulting in a low throttling performance of the technical solution.
