Abstract
The invention provides a kind of membrane valve and production method thereof with ceramic lined, easily aging to overcome rubber or plastic lining membrane valve lining, wear no resistance shortcomings such as easy pollution medium and life-span weak point.It has extremely strong rotproofness, and high wear-resisting, anti-scouring capability can pollution medium, and lining is never aging, and working life is very long and can adapt to very wide medium temperature scope; Production technology is simple, and the outside Conncetion cimension of each of valve is processed by NBS easily, thus can be general on existing pipeline easily, can be widely used in industries such as oil, chemical industry, metallurgy, pharmacy, light industry.
Description
The present invention relates to valve class device, a kind of membrane valve with ceramic lined.
The introduction of the 456 pages of membrane valves of valve products handbook that publish and distribute from hydraulic and electric engineering publishing house in October, 1989 front page knows that existing membrane valve product, its body cavity all are line with rubber or lined with fluoroplastic material; According to another the most novel at present optimal corrosion-resistant diaphragm valve of Economic Information Daily second edition report China on December 9 nineteen ninety-polyvinylidene fluoride lining membrane valve (by peace
Dangshan County valve plant and Shanghai organic fluorine material research institute develop jointly) also be a kind of membrane valve of fluoroplastics lining, this report points out also that simultaneously the Polyvinylidene chemical resistance is still relatively poor, can be decomposed by oleum, by the big organic solvent dissolution of polarity.Line with rubber or lined with fluoroplastic material exist all that lining is aging, working life short, wear-resisting difference produces the ionic soil medium and cost of production than problems such as height.Pottery then is to have advantageous advantage, and it has extremely strong widely resistance to corrosion, high temperature resistant, not aging, wear-resisting anti-washing away, thereby be desirable valve body material.But owing to be difficult to carry out machining, can not carry out standardized production, therefore simple valve body with ceramic making connects to pipeline and replaces existing common lining membrane valve and bring difficulty.
The purpose of this invention is to provide a kind of ceramic lined membrane valve production method, make it be easy to realize standardized production, technology is simple, cost is low, easy to maintenance.
Purpose of the present invention adopts following proposal to realize.
1, the membrane valve valve body is with whole ceramic body lining, and its technology mainly is:
1) will make the liner of valve body by whole ceramic body of required specification sintering setting, two of this lining is designed to flange mouth or thick mouth without turn-ups, thereby can play good seal action when being connected with pipeline, in order to avoid medium contact valve shell.
2) valve shell carry out with organic or inorganic binder and ceramic body liner bonding, solidify the back form a bonding firmly, can tolerate whole valve body of various medium temperatures.
3) valve shell adopts intensity, good rigidity and is easy to carry out the material (as metallic material or other materials such as iron and steel) of machining.The outside fit dimension that connects of each of shell is pressed the processing of membrane valve NBS.
2, barrier film adopts one deck fluoroplastic and one deck rubber plate, and fluoroplastic are at nexine, and rubber plate is at skin.Because fluoroplastic have good resistance to medium and rubber plate that good plastic deformation characteristics are arranged, so medium can be isolated in pipeline well, the bad back of fluoroplastic is changed easily, rubber plate can select for use different temperature resistant rubbers to make according to different medium temperatures, makes cost of production more reasonable.
Be the enforcement that example illustrates the present invention program below with the manual diaphragm valve.
Accompanying drawing 1 is a ceramic lined manual diaphragm valve schematic representation, and valve shell adopts ferrous materials.
The left and right valve shell of whole ceramic body liner of 1-2-
The left and right valve shell connecting bolt of 3-4-concave-convex shape fluoroplastic
5-concave-convex shape rubber plate 6-sphere shape flap
7-valve upper cover 8-screw rod
9-nut 10-handwheel
The 11-adhesive layer
Valve body manufacturing process embodiment: will be the sintering setting whole left and right two semi-involutions of ceramic body liner 1 usefulness iron and steel valve shell 2 inclusions therein, left and right sides two halves housing links into an integrated entity by five connecting bolts 3; Leave certain interval between liner 1 and the shell 2, the organic or inorganic binder is filled in the gap with perfusion or gluing method.Technique for sticking is looked selected binder and is different, for example:
One, selects organic adhesive for use.This example is with epoxy resin E-44: curing agent
#593=100: 20 batching glues, carry out following operation after mixing stirs evenly under the normal temperature:
1, the bonding plane of shell and ceramic body liner is cleaned to not having greasy dirt, drying.
2,1 pair of whole ceramic body liner is combined in the left and right two halves iron-clad body 2, links into an integrated entity with five connecting bolts 3 again.
3, with the thicker good binder of pairing curing is sealed at this valve body two earlier.In other end (making progress) is poured into binder in gap between ceramic body liner and the iron-clad body, make it to fill with then, solidified at room temperature 12 hours.
The pottery lining valve body of so making, integrity is strong, the mechanical strength height, the corrosion resistant ability is strong, and Applicable temperature is less than or equal to 100 ℃.If adopt DG-4 optical clear glue binder bonding, solidify under the room temperature, Applicable temperature can be brought up to and be less than or equal to 150 ℃.
Two, select inorganic adhesive for use: this example is selected C-2 glue for use, and this glue Main Ingredients and Appearance is an alumino-silicate, and single package can directly use, and the double pack product are by first (solid): second (liquid)=2 gram: 1 milliliter of proportioning is mixed well into glue.Operate as follows:
1, gluing, with glue be applied to cleaning treat again 1 pair of liner is combined in the left and right sides iron-clad body 2 on the sticking face (whole ceramic-lined outer surface, left and right half shell shell inner surface), and connect with five connecting bolts 3, extrude unnecessary binder the position, space is filled up fashionable.
2, solidify, after room temperature is placed 12 hours, solidified 2 hours down earlier at 80 ℃.
Above gluing operation also can change into pours into bonding by precedent like that.
The pottery of making by this example serves as a contrast valve body corrosion resistance extra-heavy and the solvent of anti-the organic or inorganic.Above method is equally applicable to produce various membrane valves with whole of the lining that materials such as glass, glass fibre reinforced plastics, corrosion resistant engineering plastics are made.
Advantage of the present invention is to produce various diaphragm valves with ceramic lined with comparatively simple method. This diaphragm valve valve body has extremely strong decay resistance, and media-resistant washes away, wear-resisting, not pollution medium; Can adapt to the various medium temperatures from low temperature to high temperature; Lining is never aging, long service life; Each size for connection of valve is easy to by national standard processing, thereby is implemented in easily the connection in the existing pipeline, replaces the General Purpose Rubber diaphragm valve.
