Abstract
The utility model relates to a wear-proof ceramic high-pressure angle type regulating valve, and belongs to the field of valves. A valve cavity, a medium inlet flow channel and a medium outlet flow channel are formed in a valve body, wherein the medium inlet flow channel and the medium outlet flow channel are communicated with the valve cavity. The medium outlet flow channel of the valve cavity is lined with a wear-proof ceramic pipe, packing for sealing a valve rod is arranged in a valve cover, a packing gland is arranged above the packing, a packing pressing plate is arranged above the packing gland, the packing pressing plate is tightened on the valve cover, a pressing disc presses the valve cover and is fixedly connected with the valve body, a guide sleeve is installed in the valve cover, the valve rod is installed in the valve cover in a movable sealing mode, a valve element is fixedly installed at the tail end of the valve rod, the valve rod is in sliding connection with the guide sleeve, a valve cage is arranged in the valve body and presses a valve seat, and the valve cover presses the valve cage. The service life of the valve seat is greatly prolonged, the valve element is prevented from being eroded by a flowing high-pressure medium, the outlet side is lined with the ceramic wear-proof pipe, and therefore erosion of the medium to a pipeline is greatly reduced, and the service life of the valve is prolonged.
Description
Technical field
The utility model belongs to a kind of modulating valve, particularly a kind of wear-resistant ceramic high-pressure angle type regulating valve.
Background technique
In ature of coal natural gas system, gasification oven produce Pipeline transport process in, owing to containing a certain amount of coal, ash and tar in medium, very strict to the requirement of valve, require valve to there is high-pressure anti-wear, resistance to erosion, good antiscale property, the functions such as scab proof.Medium makes valve seat in traditional single-seat valve, spool rapid wear and outlet easily wash away and cannot use.For similar this kind of operating mode, must there is special modulating valve to control.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of wear-resistant ceramic high-pressure angle type regulating valve is provided, can greatly extend valve seat working life, can prevent that the valve outlet damaged on end causing with cavitation erosion of high velocity fluid strikes is bad.
The purpose of this utility model is achieved through the following technical solutions, a kind of wear-resistant ceramic high-pressure angle type regulating valve, it is characterized in that: it comprises valve body, valve seat, valve rod spool, valve cage, valve gap and platen, in valve body, be provided with medium inlet channel and media outlet runner that valve pocket and valve pocket are communicated with, the media outlet runner wear-resistant ceramic of lining pipe of valve pocket, in valve gap, be provided with the filler for sealed valve stem, the top of filler is provided with Gland, Gland top is provided with hold-down grid, hold-down grid is fastened on valve gap, platen is pushed down valve gap, fix with valve body, guide sleeve is installed in valve gap, in valve gap, movable sealing is provided with valve rod, the bottom fixed installation spool of valve rod, valve rod and guide sleeve are and are slidably connected, in valve body, be provided with valve cage, valve cage is pushed down valve seat, valve gap is pushed down valve cage.
Between described valve gap and valve body, be provided with spirotallic gasket.
Between described valve seat and valve body, be provided with spirotallic gasket.
