It asks.
To achieve the above object, the utility model adopts the following technical solution.
A kind of multi-step pressure reduction throttling set, including multiple throttling plates, the throttling plate is plate-like, is set in the end face of throttling plate
There are multiple throttle orifices, the throttle orifice penetrates throttling plate, and is gone back in array distribution, throttling plate around the central axis of throttling plate
Equipped with multiple baseline positioning holes, the distance of baseline positioning hole and central axis is less than the distance of throttle orifice and central axis, described
Baseline positioning hole is around central axis around array distribution；Further include fixed link, the baseline positioning hole on multiple throttling plates is wrong successively
It opens and is sleeved in fixed link and be connected with each other.
Throttling plate carries out decompression throttling to moving fluid in the fluid passage for fixation, and fluid is made to pass through from throttle orifice
Fluid flow, speed are controlled, adjusts the pressure inside fluid channel, to realize flexibly free regulatory function, the utility model
Multiple throttling plates are used in series, and throttle orifice are made once to be staggered certain distance by baseline positioning hole, are realized into one
The further control of flow, speed is walked, throttle orifice is interconnected channel in the shape of a spiral, passes through and different staggered angles is selected during installation
Different interval is selected to realize flexible and changeable subtract between degree, different throttling disc thicknesses, different throttling plate quantity and throttling plate
Press restriction effect.
Advanced optimizing for said program is further included, the throttle orifice around central axis array when adjacent throttle orifice it
Between angle α be more than baseline positioning hole around central axis around array when adjacent baseline positioning hole between angle β.Using above-mentioned
Limitation ensures that throttle orifice can be interconnected, adjacent throttling plate is avoided to block throttle orifice, corresponding throttle orifice is made to connect successively
It is logical, it is positioned convenient for assembling.
Advanced optimizing for said program is further included, the fixed link is welding wire, the origin reference location on the throttling plate
Hole is sequentially sleeved on welding wire, and both ends are fixed by spot welding.It is fixed and welded by welding wire, it is convenient for disassembly and assembly.Connection is reliable, convenient for stream
The installation of body channel interior is conducive to improve fixed effect and efficiency of assembling.
Advantage is：A kind of multi-step pressure reduction throttling set of the utility model, it is simple in construction, easy to disassemble and assemble, lead to
Different modes when crossing the design or assembling of the throttle orifice, baseline positioning hole of throttling plate realize a variety of different decompression throttling effects
Fruit, wherein throttling plate, which are how used alone, to be freely combined, and can flexibly be used, be filled using the throttling as needed
It puts, fluid channel can be reduced and impacted by the punching press of fluid, channel interior structure is protected, adjust internal pressure, flow velocity, reduction is shaken
Phenomena such as moving, and then improving safety and the stability of equipment entirety, avoid piping failure, vibrating noise, cavitation generates.
