Embodiment
Below in conjunction with accompanying drawing, also by embodiment, the present invention is described in further detail, and following examples are explanation of the invention and the present invention is not limited to following examples.
See Fig. 1 ~ Fig. 5, the embodiment of the present invention comprises pedestal 1 and pressure reduction container 2.Pressure reduction container 2 comprises spiral chute sleeve column, sealing tub assembly and gasket assembly.
Pedestal 1 has inlet channel 7, outlet flow 8, import 14 and outlet 15; Import 14 is communicated with inlet channel 7; Outlet flow 8 is communicated with outlet 15.Be provided with shunting section 16 in inlet channel 7, play shunting action.Be provided with interflow section 17 in outlet flow 8, play interflow effect.
Sealing tub assembly comprises sealing bucket 5 and end cap 4.The bottom of sealing bucket 5 is fixed on pedestal 1, has sealing barrel cavity 9 in sealing bucket 5.
End cap 4 is fixed on sealing bucket 5, is sealed up by sealing barrel cavity 9.
Spiral chute sleeve column is formed by combined set successively outside within multiple spiral groove sleeve 3.
The outer wall of spiral groove sleeve 3 has spiral chute 10, and spiral chute 10 around the medial axis of spiral groove sleeve 3, and extends along the axis of spiral groove sleeve 3.The outer wall of a spiral groove sleeve 3 can have many spiral chutes 10, in the present embodiment, the outer wall of a spiral groove sleeve 3 has two spiral chutes 10.Spiral chute 10 is fluids, as the passage of gas, liquid.Spiral groove sleeve 3 has spiral groove sleeve through hole 11, spiral groove sleeve through hole 11 is communicated with spiral chute 10.
Arbitrarily in inside and outside two adjacent spiral groove sleeves 3: outer field spiral groove sleeve 3 is sleeved on outside the spiral groove sleeve 3 of internal layer, these two spiral groove sleeve 3 interference fit, so just form sealing, make fluid can not infiltrate contact area between two spiral groove sleeves 3, order about fluid and flow to spiral chute 10; And the spiral groove sleeve through hole 11 of outer spiral groove sleeve 3 is communicated with the spiral chute 10 of internal layer spiral groove sleeve 3; The spiral groove sleeve through hole 11 of these two spiral groove sleeves 3 is in setting up and down, and such fluid would not directly enter another spiral groove sleeve through hole 11 from a spiral groove sleeve through hole 11, but flows through a segment distance at spiral chute 10, adds resistance.
The spiral groove sleeve through hole 11 of the spiral groove sleeve 3 of spiral chute sleeve column innermost layer is communicated with the interflow section 17 of outlet flow 8.
Gasket assembly is sleeved on outside the outermost spiral groove sleeve 3 of spiral chute sleeve column, and is lived by spiral chute 10 local complexity of this spiral groove sleeve 3, and the capped part of spiral chute 10 is: from spiral groove sleeve through hole more than 11, but less than top.Gasket assembly and this spiral groove sleeve 3 interference fit, so just form sealing, makes fluid can not penetrate into contact area between gasket assembly and spiral groove sleeve 3, order about fluid and flow to spiral chute 10.Outermost surface spiral groove sleeve 3 is not communicated with sealing barrel cavity 9 by the spiral chute 10 that gasket assembly covers.
Sealing bucket 5 is sleeved on outside gasket assembly; Gasket assembly and sealing bucket 5 interference fit, so just form sealing, the contact area making fluid can not penetrate into gasket assembly and seal between bucket 5, orders about fluid and flows to spiral chute 10.
Have packing ring runner in gasket assembly, packing ring runner one end is communicated with the shunting section 16 of inlet channel 7, and the other end is communicated with sealing barrel cavity 9.
Gasket assembly is formed by multiple packing ring about 6 successively stack combinations.
Packing ring 6 is sleeved on outside the outermost spiral groove sleeve 3 of spiral chute sleeve column, and seals bucket 5 and be sleeved on outside packing ring 6; Packing ring 6 and this spiral groove sleeve 3 interference fit, so just form sealing, makes fluid can not penetrate into contact area between packing ring 6 and spiral groove sleeve 3, order about fluid and flow to spiral chute 10; Packing ring 6 and sealing bucket 5 interference fit, so just form sealing, the contact area making fluid can not penetrate into packing ring 6 and seal between bucket 5, orders about fluid and flows to spiral chute 10.
Packing ring 6 has the packing ring through hole 12 and gasket groove 13 that are connected, packing ring through hole 12 and the gasket groove 13 of above-mentioned multiple packing ring 6 superposed successively up and down form packing ring runner.The packing ring through hole 12 of the gasket groove 13 of undermost packing ring 6 and the packing ring 6 of the superiors forms the two ends of packing ring runner, and the undermost gasket groove 13 of packing ring 6 is communicated with the shunting section 16 of inlet channel 7, packing ring through hole 12 and the sealing barrel cavity 9 of the packing ring 6 of the superiors.In the present invention, be orlop packing ring 6 with the packing ring 6 near pedestal 1.
In two neighbouring arbitrarily packing rings 6: the packing ring through hole 12 of lower floor's packing ring 6 communicates with the gasket groove 13 of upper strata packing ring 6; And the dislocation of the packing ring through hole 12 one-tenth 180 degree of neighbouring two packing rings 6 is arranged, such fluid would not directly enter another through hole 12 from a through hole 12, but flows through a segment distance at gasket groove 13, adds resistance.
Fluid flows into shunting section 16 after the import 14 of pedestal 1 flows into inlet channel 7, then pressure reduction container 2 is flow to both sides, flow to packing ring runner, sealing barrel cavity 9 is flow to through packing ring runner, after being full of sealing barrel cavity 9, fluid circulates toward interior stream along the spiral chute 10 on outermost surface spiral groove sleeve 3, when flowing to the spiral groove sleeve through hole 11 of this spiral groove sleeve 3, enters the spiral chute 10 on time outer spiral groove sleeve 3 by this spiral groove sleeve through hole 11; The spiral chute 10 of fluid on secondary outer spiral groove sleeve 3 flow to again in the spiral groove sleeve through hole 11 of time outer spiral groove sleeve 3, flow with this spiral circulation, until flow out the spiral groove sleeve through hole 11 of the spiral groove sleeve 3 of innermost layer, then flow into the interflow section 17 of outlet flow 8, then flowed out by outlet 15 through the outlet flow 8 of pedestal.
Due to fluid from import 14 to outlet 15 will through packing ring runner and multi-layer helical groove cover 3 many spiral chutes 10, resistance in process fluid flow increases, and the superposition of shunting effect, make the pressure pressure lower than import 14 place at double at outlet 15 place, reach into the effect of order of magnitude step-down multiplying power.
According to the demand importing and exporting High Pressure Difference ratio, a pedestal 1 can install multiple pressure reduction container 2, and the present embodiment is only 2.
In addition, it should be noted that, the specific embodiment described in this specification, the shape, institute's title of being named etc. of its parts and components can be different, and the above content described in this specification is only to structure example of the present invention explanation.
