Background technology
Valve is control parts in pipeline fluid induction system, for changing path section and media flow direction, has
The functions such as water conservancy diversion, cut-off, throttling, non-return, shunting or overflow release.The valve controlling for fluid, from simplest stop valve
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.
Residual cake valve rotates handwheel and promotes valve rod to move up and down the switch completing valve together with flashboard by valve stem nut
Action.The sealing surface of flashboard is fitted tightly with valve seat by wedge structure, defines rigid seal, overcomes any economy pair
The impact of sealing simultaneously can prevent granule medium from entering between sealing surface, it is possible to achieve two way seal, in the keying of residual cake valve
Cheng Zhong, the continuous shearing of seat sealing surface motion that flashboard againsts valve seat is possible to be bonded on valve seat in technical process with cleaning
Medium.Devise slag guiding trough in the valve pocket of valve body, do not deposit slag, open and close flexibly, ceramic seal pair makes the abrasion resistance properties of valve big
Big raising.
Utility model content
The purpose of this utility model is to improve the deficiency of prior art, provides a kind of Wear-resistant ceramic slag removal valve, metal to-metal brake
The wedge shape gathering sill being designed with wedge structure and valve body after backboard promotes flashboard to be closely fitted on ceramic valve seat it is ensured that valve
The sealing effectiveness of door, it is possible to achieve two way seal；, all using structural ceramic material, sealing pair have passed through for sealing auxiliary gate-board and valve seat
The zero leakage of valve is realized, structural ceramicss have self-lubricating property, the unlatching moment of torsion of valve simultaneously after pairing abrasive polishing process
Little；Devise slag guiding trough in the valve pocket of metal valve body, do not deposit slag；Wear-resistant ceramic is designed with the medium runner of valve pocket
Layer, provides the wear-resisting and decay resistance of valve on the whole.
For realizing this utility model purpose, there is provided technical scheme below: a kind of Wear-resistant ceramic slag removal valve, including metal valve
It is characterised in that metal valve body is three-port structure, metal valve body left end runner assembles left flange, the valve seat in the hole on left flange to body
Ceramic valve seat is installed, top runner is provided centrally with valve rod, valve rod lower end is provided with flashboard, flashboard include metal flashboard and
It is embedded in the ceramic flashboard of metal flashboard one side, ceramic flashboard and ceramic valve seat cooperate, and metal flashboard another side is centrally disposed
There is wedge shape raised line, the metal valve body sidewall below metal flashboard constitutes an ash pit, ash pit includes horizontal part and rake,
Slag trap is provided with rake, slag trap one end is connected one and rectifies bottom near to flashboard with rake, and right-hand member runner upper end sets
It is equipped with inside extension, extension nearly top just to flashboard, extension and slag trap offer wedge shape towards the end of flashboard
Gathering sill, wedge shape gathering sill is coordinated with the wedge shape raised line of flashboard.
Preferably, right-hand member runner is lined with ceramic wear-resistant coating.
Preferably, top runner top connects bonnet, bonnet, and the joint face of top runner are provided with graphite
Pad.
Preferably, left flange is provided with Graphite pad with the joint face of metal valve body.
This utility model beneficial effect: general structure design is short and sweet, it is in the design of the behind of metal flashboard first
There is wedge structure, the inner chamber of valve body is designed with wedge shape gathering sill, driving means drive valve rod together with flashboard by valve stem nut
Lower movement, flashboard is close on valve seat, and sealing is reliable and stable, it is possible to achieve two way seal, effectively overcomes economy to valve
Impact；Next to that the sealing pair of Wear-resistant ceramic slag removal valve is to adopt structural ceramic material, i.e. ceramic flashboard and ceramic valve seat, pottery
Ceramic ring and ceramic valve seat seal more reliable, because ceramic material also has self lubricity after supporting abrasive polishing process is processed
Can, coefficient of friction is little, and valve opening and closing moment of torsion is little.Three is all to be designed with ceramic coating on the medium runner of valve body, in valve pocket
Portion is designed with slag guiding trough, does not deposit slag, provides the wear-resisting and decay resistance of valve on the whole.
Therefore, this utility model disclosure satisfy that the technical requirements using scene, is particularly well-suited to various powders, granule, slag
In aqueous mixtures, ore pulp material equigranular mixture condition, the high life of valve, ensure that the safety of production and operation enterprise is steady
Fixed operation, obtains good economic benefit.
