Abstract
A ceramic sliding plate control valve comprises an air cylinder, a valve support, a valve rod and a valve body, wherein at least one a ceramic fixing valve plate perpendicular to the medium flow direction is fixedly arranged in the valve body, throttling holes with the same width and different lengths are formed in the ceramic fixing valve plates, a ceramic sliding plate connected with one end of the valve rod is arranged in the valve body, the ceramic sliding plate is tightly attached to the fixing valve plates, throttling holes corresponding to the ceramic fixing valve plates are formed in the ceramic sliding plate, one end of the valve rod is connected with the other end of the ceramic sliding plate, then, passes through the valve support and is connected with the air cylinder, the ceramic sliding plate can move under the action of the air cylinder, the size of the medium flowing area is changed, and therefore the medium flow is controlled.
Description
Technical field
The utility model relates to a kind of gate valve being arranged in media feed system, is specifically related to a kind of ceramic gate valve.
Background technique
The gate valve tool being arranged in media feed system has been widely used, and is mainly used in the conveying of various media, in course of conveying whole system in hermetically sealed, without leak condition.Ceramic valve is better than other materials at aspect of performances such as resistance to chemical attack, wear-resistant, high temperature resistant, resistance to erosion, and therefore ceramic valve is widely used in being difficult to use under the mal-condition of metal or other materials.There are a lot of defects in existing ceramic valve, is badly in need of improving, and butterfly valve is not closed completely, and leakage rate is large, and lining fluorine material aging is out of shape, breaks.V-type ball is uncompensated after the wearing and tearing of valve use a period of time spool, valve seat, and Spool rotating is dumb, and why interior leakage, outer leakage quantity progressively add, and are not closed completely.The straight journey linear sealing of single-seat valve.When pressure reduction is large before and after valve, easily utters long and high-pitched sounds and vibrate, serving as a contrast fluorine material deformation, break.Also have above valve all not wear-resistant, it is poor that lining material adapts to the performance of expanding with heat and contract with cold, and working life is short.
Model utility content
The purpose of this utility model is, a kind of have simple in structure, long service life, ceramic sliding control valve without advantages such as obstruction, zero leakages are provided.
For reaching above-mentioned technical purpose, provide following technological scheme:
Ceramic sliding control valve, comprises cylinder, valve rack, valve rod and valve body, wherein in valve body, is installed with at least one and fixes valve plate with MEDIA FLOW to vertical pottery, has the throttle orifice of same widths different length on the fixing valve plate of this pottery; The ceramic sliding being connected with valve rod one end is also installed in described valve body, and this ceramic sliding is close on fixing valve plate, also has the throttle orifice corresponding with the fixing valve plate of pottery on it; Described valve rod one end connects the ceramic sliding the other end and connects cylinder after by valve rack, ceramic sliding can be moved under the effect of cylinder, thereby change the flow of the size control media of medium circulation area.
For making the utility model more be suitable for practicality, make further improvements below:
Further, the fixing valve plate of described pottery is two uses together, and ceramic sliding is close in left and right respectively.
Further, the fixing valve plate of described pottery is close to ceramic sliding on one side, and another side is full runner ceramic lined structure.
Further, the attachment portion between the fixing valve plate of described pottery and valve body adopts seal with elastometic washer, with Leakage prevention.
Further, between described valve rod and valve body, adopt radial seal.
Further, between the fixing valve plate of described pottery and valve body, be provided with butterfly spring.
Further, described valve body two ends are provided with ceramic flange end face, so that can not affect because of pretightening force the pressure of slide plate both ends of the surface while being arranged on pipeline.
The beneficial effects of the utility model are: the sealing between slide plate and valve seat is face sealing, linear sealing relatively (as ball valve etc.), even if part sealing surface is damaged, the face of periphery can continue to seal, so the long service life of modulating valve.Motion between slide plate and valve seat is shearing motion, thus be bonded in solid dielectric on slide plate or valve seat be easy to cleaned fall.Zero leakage is mainly (slide plate of sluice valve and valve seat surface roughness and flatness are all less than 3um) guaranteeing by machining accuracy, the upper lower valve base of sluice valve has spring system behind, sluice valve can make up the loss of friction, so can be accomplished lifelong zero leakage.And the dust that is less than sealing surface roughness and flatness due to diameter can enter between sealing surface, these media can not scratch sealing surface, can not increase friction yet, make on the contrary sealing effect become better and better, because these dust have been filled up the space between rough surface.When valve from standard-sized sheet to complete shut-down process, medium is only likely temporarily piled up in ceramic sliding throttle orifice, when valve by complete shut-down in the process of standard-sized sheet, all accumulation mediums all enter pipeline, have not a particle of residual (valve pocket of ball valve easily stops up).

Embodiment
Ceramic sliding control valve, comprises cylinder 1, valve rack 2, valve rod 3 and valve body 9, wherein in valve body 9, is installed with at least one and fixes valve plate 8 with MEDIA FLOW to vertical pottery, has the throttle orifice 6 of same widths different length on the fixing valve plate 8 of this pottery; The ceramic sliding 7 being connected with valve rod 3 one end is also installed in described valve body 9, and this ceramic sliding 7 is close on the fixing valve plate 8 of pottery, also has the throttle orifice 6 corresponding with the fixing valve plate 8 of pottery on ceramic sliding 7; Described valve rod 3 one end connect ceramic sliding 7 the other ends by the rear connection cylinder 1 of valve rack 2, and ceramic sliding 7 can be moved under the effect of cylinder 1, thereby change the flow of the size control media of medium circulation area.
For making the utility model more be suitable for practicality, make further improvements below:
Further, the fixing valve plate 8 of described pottery is two uses together, and ceramic sliding 7 is close in left and right respectively.
Further, the fixing valve plate 8 of described pottery is close to ceramic sliding 7 on one side, and another side is runner 10 ceramic lined structures.
Further, the attachment portion between the fixing valve plate 8 of described pottery and valve body 9 adopts rubber ring 4 to seal, with Leakage prevention.
Further, between described valve rod 3 and valve body 9, adopt radial seal.
Further, between the fixing valve plate 8 of described pottery and valve body, be provided with butterfly spring 5.
