Abstract
The invention relates to a fluid damper, which is used for stabilizing the flow rate of materials from an outlet of a delivery pipe so as to promote the reliability of automatic ignition and flame detection of a burner and improve the condition for mixing fluid materials and air. A sleeve of the fluid damper is mounted concentrically, and the gap part is provided with threads or a single-head or multi-head spiral body so as to form one or more slender damping holes for limiting the increase of the material flow rate.
Description
Affiliated technical field
This fluid damper is the burner annex, and the flow velocity that is used for the limit fluid material increases, and then the flow velocity of stable transfer pipeline outlet material, improves the reliability of automatic igniting of burner and flame detecting, improves fluid foods and air mixing condition.
Technical background
At present, for guaranteeing the reliability of burner automatic ignition and accident extinguishing safeguard protection, generally to increase small fire burner, more complicated.Atmospheric gas burner is air regulating board regulating power deficiency when supply gas pressure is excessive, the mixing ratio superelevation.General damper structure complexity, or require the machining accuracy height, inconvenience is promoted.
Summary of the invention
The technical problem that solves
For overcoming damper the problems referred to above, to design simple in structurely, performance is good, the fluid damper that cost is low,
Be convenient to promote in the burner industry.
Technical scheme
Propose following technical scheme, in the gap of the concentric sleeve of single or multiple lift, be shaped on screw thread, or the spiral thing of packing into, screw thread and spiral thing are single head or bull.The gap of pitch and sleeve wall form the elongated damping hole of multi-turn, and the end of outermost sleeve has a cavity, converges the outlet of whole damping holes, form the parallel connection of damping hole.The hole of the sleeve of innermost layer is the straight line damping hole.
These damping holes can replace many thin and long damper tubes.
Beneficial effect
This damper structure compactness, good manufacturability, material-saving, cost reduces by 50%.If become compact like this damper with real tube construction, quite complicated, manufacturability is poor, the cost height.
Description of drawings
Fig. 1 is the fluid damper of individual layer
Fig. 2 is double-deck fluid damper
Among the figure:
1---the 1st layer of sleeve (outermost layer sleeve)
2---the 2nd layer of sleeve
3---the 3rd layer of sleeve (being the innermost layer here, band line thread damping hole)
4---cavity
5---straight line damping hole (being screwed hole here)
6---conveyor screw (being helical spring here)
The import of JK---fluid
The outlet of CK---fluid
Concrete embodiment
Among Fig. 1, the 3rd layer of sleeve (3) is contained in the 1st layer of sleeve (1) lining, is placed with multi-head spiral body (6) in both gaps coaxially, and this example is a helical spring.Spring is also not tight, and pitch leaves the gap, then forms many damping holes of spirality with sleeve wall, and damping hole is carefully grown.The end of outermost sleeve (3) has a cavity (4), converges the outlet of whole damping holes, forms the parallel connection of damping hole.Fluid flows into from import JK, flows out from CK.Here, sleeve (3) is the innermost layer, band line thread damping hole.
Fig. 2 is coaxial again the 2nd layer of sleeve (2) (also can increase more multi-layered) of having installed between the 1st layer of sleeve (1) and the 3rd layer of sleeve (3), forms a large amount of damping holes, satisfies the needs of big flow.The conveyor screw of this example is the canine tooth screw thread of directly making on sleeve.The same Fig. 1 of other structure does not give unnecessary details.
Claims (5)
1 damper is made of housing and damping piston, damping fin or damper tube, and this fluid damper has been characterised in that between the sleeve with one heart structure single head or multi-head spiral body forms one or more elongated damping holes.
The feature of 2 claims, 1 described fluid damper is: but damper multilayer suit is coaxially formed a large amount of damping holes in parallel.
The feature of 3 claims, 1 described fluid damper is: the end of outermost sleeve has a cavity, converges the outlet of whole damping holes, forms the parallel connection of damping hole.
The feature of 4 claims, 1 described fluid damper is: conveyor screw be the screw thread made or on axle the coiling conveyor screw.
The feature of 5 claims, 1 described fluid damper is: the sleeve of innermost layer has the straight line damping hole.
