The various valves used in extremely complex robot control system(RCS), its kind and specification are various, and the inside nominal diameter of valve is from atomic little
Gauge valve reach greatly the industrial pipeline valve of 10m to latus rectum.Can be used for controlling water, steam, oil product, gas, mud, various corrosion
The all kinds such as property medium, liquid metal and radioactive fluid fluidly flow, and the operating pressure of valve can be from
The supertension of 0.0013mpa to 1000mpa, operating temperature can be with the high temperature of c-270 DEG C of ultralow temperature to 1430 DEG C.
The driving means that valve cut by disk make the certain angle of valve disc rotation realize opening of valve by valve rod with driving rocking arm
Pass action.The sealing surface of valve disc is fitted tightly with valve seat by spring, and spring pressure makes valve disc be fitted tightly on valve seat all the time,
Allow valve disc to have displacement in the vertical direction of sealing surface, this helps compensate for valve partses and causes due to expanding shrinkage again
The micro abrasion producing after deformation and multiple switching, overcomes the impact to sealing for any economy and can prevent granule medium from entering
Enter between sealing surface, in the opening-closing process that valve cut by disk, the difference of valve disc frictional force in tangential direction faced by valve base sealing,
Make valve disc one open and close cyclic process in produce rotation and can constantly shear and clean be possible in technical process pile up
Medium in valve pocket.
Utility model content
The purpose of this utility model is to improve the deficiency of prior art, provides a kind of ceramic disk to cut valve, its metal upper valve
, using eccentric design, driving means realize switch motion by slip valve disc, and bivalve dish structure designs, and is opening for body and lower valve body
During pass, spring pressure makes valve disc be fitted tightly on valve seat all the time, allows valve disc to have position in the vertical direction of sealing surface again
Move, this helps compensate for the micro abrasion that valve partses produce after the deformation that causes and multiple switching due to expanding shrinkage, gram
Take the impact to sealing for any economy and can prevent granule medium from entering between sealing surface；Valve disc is during sliding
Because frictional force has rotation so as to have self-grind and self-cleaning function, make ceramic disk cut valve and use more reliable, raising
The service life of valve.
For realizing this utility model purpose, provide technical scheme below: on a kind of ceramic disk cuts valve it is characterised in that including
Under spaced upper and lower metal valve body, be arranged between upper and lower metal valve body, positioned at the intermediate valve at upper and lower metal valve body two ends
Body, upper and lower metal valve body and center valve body constitute sealing valve pocket, and upper metal valve body is located at that center is to the left to be provided with valve opening, lower gold
Belong to valve body and be symmetrically arranged with lower valve opening, in upper and lower valve opening, be mounted on upper and lower ceramic valve seat, it is to the right that upper metal seat valve is located at center
It is provided with valve rod hole, valve rod in the hole is provided with valve rod, valve rod hole top is provided with gland, valve stem end connects horizontal drive
Rocking arm, horizontal drive rocking arm is located on the central axis of sealing valve pocket, and horizontal drive rocking arm left end connects adapter sleeve, adapter sleeve two
End is inserted in the countersunk head in the hole of the symmetrical valve disc of metal up and down, is provided with spring in adapter sleeve, upper and lower metal valve disc respectively with upper
Lower ceramic valve seat cooperates.
Preferably, upper and lower metal valve disc is provided with ceramic ring with the contact surface of upper lower valve base.
Preferably, wearing studs between upper and lower metal valve body, spun by nut.
Preferably, center valve body two ends are provided with o type circle with the contact surface of upper and lower metal valve body.
Preferably, being provided with packing box assembly between valve rod hole and valve rod, packing box assembly includes stuffing-box and dust ring.
Prevent live bad working environments medium from entering in stem structure, cause to damage the serious of valve rod and intensifying valve moment of torsion
Consequence.
In order to realize the purpose of this utility model further, drive and size two-layer bullet is set in the tubular type structure of rocking arm
Spring.Blind hole structure can also be adopted.Spring supporting block structure can also be adopted, i.e. spring contact drives rocking arm, and support block contacts
Valve disc.
This utility model beneficial effect: general structure design is short and sweet, it is that on metal, lower valve body all employs first
Eccentric structure designs, and valve rod hole is also eccentric structure on upper valve body, and such driving means can be by valve rod and driving rocking arm
Make valve disc rotate certain angle, realize the switch motion that ceramic disk cuts valve.Next to that devising two valve discs, in switching process
Middle spring pressure makes valve disc be fitted tightly on valve seat all the time, allows valve disc to have displacement in the vertical direction of sealing surface again, this
Help compensate for the micro abrasion that valve partses produce after the deformation that causes and multiple switching due to expanding shrinkage, overcome any
Economy to the impact sealing and can prevent granule medium from entering between sealing surface；Three is that ceramic disk cuts the employing of valve sealing pair
Ceramic material, i.e. ceramic ring and ceramic valve seat, ceramic ring and ceramic valve seat seal more after supporting abrasive polishing process is processed
Reliable, because ceramic material also has self-lubricating property, coefficient of friction is little, and valve opening and closing moment of torsion is little.Four is that ceramic disk cuts valve
Valve disc because frictional force has rotation so as to have self-grind and self-cleaning function, makes ceramic disk during sliding
Cut valve using more reliable, improve the service life of valve.Five is that stuffing-box modular design has dust ring, prevents the severe work in scene
Condition granule medium enters in stem structure, causes to damage the serious consequence of valve rod and intensifying valve moment of torsion.
Therefore, this utility model disclosure satisfy that the technical requirements using scene, is particularly well-suited to various powders, granule and slurry
In material equigranular mixture condition, the high life of valve, ensure that the safe and stable operation of production and operation enterprise, obtain good
Good economic benefit.
