Problems solved by technology

[0002] In the prior art, most of the internal decompression used in high-pressure pipelines are decompression valves or buffer tanks. The decompression effect is achieved by multi-stage shunting or increasing the flow cross-sectional area. The disadvantage is that the processing and manufacturing of decompression components is complicated. In addition, The installation is also more complicated, and the equipment cost is relatively high
The traditional pipeline depressurization device has a narrow application range. In order to avoid the depressurization element being blocked by small solid particles, it can only be applied to single-phase fluid depressurization without solid particles in the medium.

Embodiment Construction

[0008] Such as figure 1 As shown, the pipeline depressurization device includes a main body of the pipeline decompression device composed of a straight pipe section 4 and a neck flange 5, and the rectangular hole diverter plate 1 and the rectangular hole diverter plate 2 are superimposed to form a multi-stage depressurization group. , the positioning ring 3 is welded on the inner wall of the pipeline to fix the pressure reducing element. Rectangular hole diverter plate 1 and rectangular hole diverter plate 2 form a rectangular hole step-down group according to the principle of parallel rectangular flow channel walls. The walls are stacked vertically, with the XX' axis as the center line, and multiple pairs of rectangular hole pressure-reducing elements are stacked to form a multi-stage pressure-reducing group of the pipeline pressure-reducing device. The pressure-reducing group can be adjusted according to the pressure values ​​of the medium at the inlet and outlet of the pipe...

Abstract

The invention discloses a pipeline depressurization device which aims at achieving a depressurization purpose by improving a turbulence effect of media in a flow channel, intensifying flow friction and clash of the media in a flow process, and consuming the energy of the flow media. The device comprises a pipeline depressurization device main body consisting of a straight-tube section (4) and hubbed flanges (5), wherein rectangular hole guide disks (1) and rectangular hole shunt disks (2) are superposed to form multi-stage depressurization groups, and locating rings (3) for fixing depressurization components are mounted on an inner wall of a pipeline.

Description

technical field [0001] The invention relates to a pipeline decompression device with a disc-type decompression element. Background technique [0002] In the prior art, most of the internal decompression used in high-pressure pipelines are decompression valves or buffer tanks. The decompression effect is achieved by multi-stage shunting or increasing the flow cross-sectional area. The disadvantage is that the processing and manufacturing of decompression components is complicated. In addition, The installation is also complicated, and the equipment cost is relatively high. The traditional pipeline decompression device has a narrow application range. In order to avoid the decompression element being blocked by small solid particles, it can only be applied to single-phase fluid decompression without solid particles in the medium. Contents of the invention [0003] The purpose of the present invention is to increase the turbulence effect of the medium in the flow channel, int...
