Abstract
The invention discloses a ceramic disk cutting valve reliable in sealing, resistant to high temperature and very good in abrasion resistance, self-grinding performance and self-cleaning performance. The ceramic disk cutting valve comprises an upper valve body, a lower valve body, an intermediate valve body, a valve rod, a stuffing box combination, a stuffing gland, springs, ceramic valve seats, metal valve disks, ceramic rings, a drive rocker arm, O-shaped rings, studs and double nuts, wherein the upper valve body and the lower valve body are made of metal. A valve disk of the valve is formed by the metal valve disks and the ceramic rings, and two pairs of ceramic sealing pairs are formed by the ceramic rings and the ceramic valve seats. A drive device makes the valve disk to rotate by a certain angle through the valve rod and the drive rocker arm to achieve the opening and closing actions of the valve.
Description
Technical field
The invention belongs to universal machine valve technology field, particularly relate to a kind of ceramic disk and cut valve.Its structure realizes the action of valve fast opening and closing by slip valve disc.
Background technology
Valve is control parts in pipeline fluid induction system, is used for changing path section and media flow direction, have water conservancy diversion, end, throttle, non-return, the function such as shunting or overflow release.The valve controlled for fluid, various valves used from simplest stop valve to extremely complex robot control system(RCS), its kind and specification are various,
The inside nominal diameter of valve reaches greatly the industrial pipeline valve of 10m from atomic little gauge valve to latus rectum.Can be used for control water, steam, oil product, gas, mud, various Korrosionsmedium,
The all kinds such as liquid metal and radioactive fluid fluidly flow, the operating pressure of valve can supertension from 0.0013MPa to 1000MPa, operating temperature can be with the high temperature of the ultralow temperature to 1430 DEG C of c-270 DEG C.
Dish is cut the driving means of valve and is realized the switch motion of valve by valve rod and the angle driving rocking arm to make valve disc rotation certain.The sealing surface of valve disc fits tightly with valve seat by spring, spring pressure makes valve disc be fitted tightly on valve seat all the time, valve disc is allowed again to have displacement in the vertical direction of sealing surface, this helps compensate for the trace abrasion that valve parts produces after the deformation that causes and multiple switching owing to expanding shrinkage, overcome the impact on sealing of any economy and can prevent granule medium from entering between sealing surface, in the opening-closing process of valve cut by dish, valve base sealing is in the face of the difference of valve disc frictional force in tangential direction, make valve disc open and close at one cyclic process produces rotation and can constantly shear and clean in technical process, be likely deposited in the medium in valve pocket.
Summary of the invention
It is an object of the invention to improve the deficiency of prior art, a kind of ceramic disk is provided to cut valve, its metal upper valve body and lower valve body use bias design, driving means realizes switch motion by slip valve disc, bivalve dish structure designs, in switching process, spring pressure makes valve disc be fitted tightly on valve seat all the time, valve disc is allowed again to have displacement in the vertical direction of sealing surface, this helps compensate for the trace abrasion that valve parts produces after the deformation that causes and multiple switching owing to expanding shrinkage, overcome the impact on sealing of any economy and can prevent granule medium from entering between sealing surface；Valve disc has rotation due to frictional force during sliding so that it is have self-grind and self-cleaning function, makes ceramic disk cut valve and uses more reliable, improves the service life of valve.
nullFor realizing the object of the invention，There is provided techniques below scheme: a kind of ceramic disk cuts valve，It is characterized in that including upper and lower spaced upper and lower metal valve body、It is arranged between upper and lower metal valve body，It is positioned at the center valve body at upper and lower metal valve body two ends，Metal valve body and center valve body constitute sealing valve pocket up and down，Upper metal valve body is positioned at that center is to the left is provided with valve opening，Lower metal valve body is symmetrically arranged with lower valve opening，It is mounted on upper and lower ceramic valve seat up and down in valve opening，Upper metal seat valve is positioned at that center is to the right is provided with valve rod hole，Valve rod it is provided with in valve rod hole，Valve rod hole top is provided with gland，Valve stem end connects horizontal drive rocking arm，Horizontal drive rocking arm is positioned on the central axis sealing valve pocket，Horizontal drive rocking arm left end connects adapter sleeve，In the counter sink of the valve disc of metal up and down that adapter sleeve two ends are inserted in symmetry，Spring it is provided with in adapter sleeve，Metal valve disc cooperates with upper and lower ceramic valve seat respectively up and down.
As preferably, upper and lower metal valve disc is provided with ceramic ring with the contact surface of upper lower valve base.
As preferably, wear studs between upper and lower metal valve body, spun by nut.
As preferably, center valve body two ends are provided with O with the contact surface of upper and lower metal valve body.
As preferably, being provided with packing box assembly between valve rod hole and valve rod, packing box assembly includes stuffing-box and dust ring.
Prevent on-the-spot bad working environments medium from entering in stem structure, cause damage valve rod and the serious consequence of intensifying valve moment of torsion.
In order to realize the purpose of the present invention further, drive in the tubular type structure of rocking arm and size two-layer spring is set.Blind hole structure can also be used.Spring supporting block structure, i.e. spring contact can also be used to drive rocking arm, a bracer contact valve disc.
The method have the benefit that general structure design is short and sweet, first it be that the upper and lower valve body of metal all have employed eccentric structure design, valve rod hole is also off structure on upper valve body, so driving means can make valve disc rotate certain angle by valve rod with driving rocking arm, it is achieved ceramic disk cuts the switch motion of valve.Next to that devise two valve discs, in switching process, spring pressure makes valve disc be fitted tightly on valve seat all the time, valve disc is allowed again to have displacement in the vertical direction of sealing surface, this helps compensate for the trace abrasion that valve parts produces after the deformation that causes and multiple switching owing to expanding shrinkage, overcomes the impact on sealing of any economy and can prevent granule medium from entering between sealing surface；Three is that ceramic disk cuts valve sealing pair employing ceramic material, i.e. ceramic ring and ceramic valve seat, and ceramic ring seals more reliable after supporting abrasive polishing process is processed with ceramic valve seat, also has self-lubricating property due to ceramic material, and coefficient of friction is little, and valve opening and closing moment of torsion is little.Four is that ceramic disk cuts the valve disc of valve during sliding owing to frictional force has rotation so that it is has self-grind and self-cleaning function, makes ceramic disk cut valve and use more reliable, improve the service life of valve.Five is that stuffing-box modular design has dust ring, prevents on-the-spot bad working environments granule medium from entering in stem structure, causes damage valve rod and the serious consequence of intensifying valve moment of torsion.
Therefore, the present invention disclosure satisfy that and uses on-the-spot technology requirement, is particularly well-suited in various powder, granule and slurry equigranular mixture condition, the high life of valve, it is possible to ensure the safe and stable operation of production and operation enterprise, it is thus achieved that good economic benefit.
