Description
Technical field
The present invention relates to a kind of flap type.
Background technique
Along with industrial expansion, flap type is more and more higher in the national economy status.It is mainly used in powder and transmits, as: aluminium oxide, magnesium oxide, silica, silica flour, white clay, talcum, the quartzy grains of sand, media such as coal dust.And, when flap type is positioned at the below of container, can serve as the effect of discharging valve; When flap type is positioned at the top of container, can serve as the effect of feed valve; When flap type is arranged in the transmission pipeline, the effect that can serve as control valve.
Aspect iron-making and steel-making, be mainly used in: pulverized coal injection in blast furnace the control that----spray gun port sprays the high density material, be used for the feed of 700 ℃ of high temperature abrasive grits of direct-reduction process; Desulfuration of foundry iron----adds auxiliary materials such as magnesium oxide, silica; Electric arc furnaces sprays carbon dust----and adds oxygen, the control of compositions such as nitrogen.
At the paper pulp manufacture view, be mainly used in: the waste water treatment of slurry: "----lime+acid solution such as waste water treatment causticization ".The adding material, add look of paper manufacturing: " adding the controls of white clay magnesium oxide, titanium dioxide, silicon, French chalk etc. ".
The flap type typical case uses to be had: the trichlorosilane of polysilicon is synthetic, organosilyl silica flour conveying system, the lock slag in the coal gasification technology, blowing, Heisui River, the control of effluent discharge etc.
The earthenware slab valve is the same with ordinary flat valve main structure and principle.Flap type is mainly by four most of compositions: left and right sides main valve body, dish spring, valve stem seal system and valve body mouth of pipe sealing system, dull and stereotyped, dull and stereotyped frame and the fixing interior sealed member formation formed of valve plate.The motion of valve is to drive the middle flat board of dull and stereotyped frame with respect to fixedly valve plate motion by valve rod, and is dull and stereotyped by doing the aperture that straight line motion comes switch valve or regulating valve.
The flap type main feature is:
1, face seal: dull and stereotyped and fixedly valve plate directly sealing be face seal, linear sealing relatively (as ball valve etc.), even the part sealing surface is damaged, the face of periphery can continue to seal, so the long service life of valve.
2, automatically cleaning: dull and stereotyped and fixedly the motion between the valve plate be shearing motion, so be bonded in flat board or fixedly the solid dielectric on the valve plate be easy to be cleaned.
3, friction is little: shearing motion make flat board with fixedly between the valve plate no diameter greater than the existence of the solid of sealing surface roughness and flatness, and diameter is very little less than the dust and the friction between the sealing surface of sealing surface roughness and flatness, it is little to wear and tear, long service life.
4, zero leakage: zero leakage mainly is (flat board of flap type and fixedly valve plate surface roughness and flatness all less than 3um) that guarantees by machining accuracy, the left and right sides valve body of flap type all has spring system behind, flap type can remedy the loss of friction, so can be accomplished lifelong zero leakage.And owing to the dust of diameter less than sealing surface roughness and flatness can enter between the sealing surface, these media can not scratch sealing surface, can not increase friction yet, and sealing effect is become better and better, because these dust have been filled up the space between the rough surface.
5, do not have to stop up: when valve from standard-sized sheet to the complete shut-down process, medium only might with the plate round hole of duct size in temporarily pile up, when valve by complete shut-down in the process of standard-sized sheet, all accumulation mediums all enter pipeline, have not a particle of residually, and the valve pocket of ordinary ball valve stops up easily.
6, complete hiding: when valve wide open, sealing surface Hide All dull and stereotyped and fixedly valve plate can not be subjected to the impact of medium, so prolong greatly working life.And the time of full-gear accounts for more than 95% of total possible wearing-in period.
Any valve has only three states, and below be its basic general knowledge: when the valve complete shut-down: the sealing surface of any valve can not impacted, and does not have wearing and tearing.When valve was half-open: any valve all can be impacted, but the time is very short, and general valve switch once has only 3-5 second.When valve wide open: the part valve can be subjected to impacting (as moushroom valve), and this state accounts for the overwhelming majority of the time that may wear and tear.
7, do not have and to leak outside: the face seal of flap type is with the interior leakage of valve and leak outside and solve together, medium can only suspend valve plate and about fixedly between the valve plate, can not let out in the valve pocket.
The design advantage of flap type is a lot, but still there is deficiency in the flap type of metallic material, the work under not competent this kind environment at aspects such as high temperature resistant, corrosion protections.Simultaneously, with the valve of ceramic material, because ceramic structures has brought great inconvenience for production and use extremely easily because the pressurized inequality causes the fragmentation of ceramic structure parts.Fixedly valve plate is an important components of earthenware slab valve, therefore, how to guarantee its safe and reliable operation, the major issue that has become the earthenware slab valve to solve.
Summary of the invention
The object of the present invention is to provide a kind of flap type of inlaying ceramic material, can satisfy the use under the mal-condition, and can guarantee the fixedly valve plate stress equalization of flap type, be difficult for broken.
Edge porcelain flap type of the present invention adopts following technological scheme:
A kind of edge porcelain flap type, comprise left valve barrel, right valve barrel, upper flange, lower flange, dish spring, valve rod outer seal member and valve body mouth of pipe outer seal member, by earthenware slab, dull and stereotyped frame and the fixing interior sealing component formed of valve plate, the first left dish spring is on left valve barrel and a left side fixedly between the valve plate, and the first left dish spring is provided with the external diameter second left dish spring bigger than the first left dish spring near fixing valve plate one side in a left side between the first left dish spring and the left valve barrel; The first right dish spring is at right valve barrel and right fixedly between the valve plate, and the first right dish spring is provided with the external diameter second right dish spring bigger than the first right dish spring near fixing valve plate one side in the right side between the first right dish spring and the right valve barrel.
