Abstract
The present invention discloses a foam glass float which mainly overcomes the defects of difficult processing, easy damage at high temperature and high pressure, single shape, high cost, etc. of the float in the prior art. The present invention is mainly characterized in that a novel foam glass material is used for making the float so that the float is used as a driving element in industry. The present invention has the advantages of rich sources of the material, low cost, easy processing, no limit of shapes, small density of the float, high temperature resistance, high pressure resistance and weak acid and alkaline corrosion resistance, floats in various shapes are processed as required, and the foam glass float is not influenced by environmental changes and can be widely used in various float-type drainage valves or liquid level control devices in industry.
Description
A kind of cellular glass float, it belongs to the silicate chemistry technical field.
Utilize in the equipment of level control (LC) at some, mostly will adopt float as the liquid level indication and as action element.In general, float is welded into hollow body after all adopting sheet metal (as: stainless steel, brass, aluminium etc.) impact briquetting, but considers stressing conditions, adopts hollow ball more.When using in high temperature, high pressure air water, float bears big pressure, and this thin-wall ball in the short period of time, is easy to be crushed out of shape and breakage under inside and outside differential pressure; On the other hand,, its volume density is increased, make buoyancy reduce (as table 1) if increase wall thickness.In addition, this float is complex manufacturing technology not only, and shape also is restricted, and especially machining, metal material cost are higher, make it not obtain widely to use in industry.
The objective of the invention is to:, the invention provides a kind of novel float and replace at present used metal floater both at home and abroad in order to overcome above-mentioned shortcoming.
Realize that the technical measures that the present invention taked are: float of the present invention is to be formed by micropore glass (being foamglass) material.Its volume density can be at 0.15～0.50g/cm
3Select arbitrarily in the scope.It is characterized in that:, be easy to be processed to the float of random geometry according to the foamglass material that different requirements is used.As shown in fig. 1: the float spherical, that the garden is annular, all can there be the various abnormity of through hole at taper, garden dish type, garden cylindricality, cube shaped, prismatoid, awl cylinder and center.
The technique effect that the present invention reached: because the foamglass material of selecting for use is a kind of porosint of vitreous closure, itself is waterproof, airtight, can bear 400 ℃ high temperature and 8～25kg/cm
3High pressure, and can weak acid resistant, the corrosion of weak base, can be because of variation flexural deformation, the pucker ﹠ bloat of environment, mechanical property is also very stable.This float starting material source is abundant, and cost price is cheap, and is very practical.This float can be widely used in that level control (LC), the steam of boiler tubing is hydrophobic, vapour coagulates the level control (LC) in water water recovery apparatus and other chemical industry.As: at present, the ball float in the loose float trap that uses mostly adopts Cr both at home and abroad
17NiMo
2The Ti material is made, if ball float shape processing difficulties, cost is higher, complex process if adopt foamglass material of the present invention to make float, coats with metal film at its working surface, can reach desirable work effect, so promptly reduce difficulty of processing, and reduce material cost.
In modern science and technology work, remote sensing, telemetry have been used for every field, and cellular glass float of the present invention not only has above-mentioned advantage, and on float inside or surface the remote measurement device can be installed, and makes its more perfect function.
For action element, the function surface of contact need coat (cellular glass float of the present invention adopts high-temperature resistant coating or protects with corrosion resistant metal film) with the corresponding protection layer to increase its surperficial physical strength, makes the surface not frayed.
With steel hollow ball shape float is example, and the computing formula of apparent volume density is:
Wherein, ρ-apparent volume density, ρ
0-steel density (is got 7.8g/cm
3), d-sheet thickness, D-spheroid external diameter.
