Abstract
The utility model discloses an abrasion-resistant ceramic high pressure angle valve and belongs to valves. A ceramic valve seat is installed on a valve body, and a fluid exit passageway of the valve body is provided with a ceramic taper pipe. The abrasion-resistant ceramic high pressure angle valve has the advantages that due to the fact that the valve seat is made of overall ceramic materials, the service life of the valve seat is prolonged greatly, and the fluid exit passageway is provided with a ceramic abrasion-resistant pipeline in a lining mode, the erosion of media to the pipeline is greatly reduced, and the service life of the valve is prolonged.
Description
Technical field
The utility model belongs to a kind of valve, and particularly the fluid of a kind of mixture with dust and solid granular at petrochemical system, deep-etching is carried the wear-resistant ceramic high-pressure angle valve that uses.
Background technique
In the Pipeline transport process of Coal Chemical Industry industry, owing to contain a certain amount of particle in the medium, very strict to the requirement of valve, require valve to have the functions such as high-pressure anti-wear, resistance to erosion, good antiscale property, scab proof.In the course of conveying of Coal Chemical Industry industry Heisui River, containing the very serious particle media of abrasiveness in the Heisui River, is quite strict to the wear-resisting requirement of valve.The abrasiveness granule medium makes traditional single-seat valve rapid wear and can't use, and solid particle is also so that traditional multi-stage sleeve step-down is no longer applicable.For similar this kind operating mode, must there be special modulating valve to control.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 valve is provided, can greatly prolong valve seat working life, can prevent high velocity fluid strikes and cavitation erosion and the valve outlet damaged on end that causes is bad.
The purpose of this utility model is achieved through the following technical solutions: a kind of wear-resistant ceramic high-pressure angle valve, comprise valve body, valve seat, valve gap, valve rod and spool, valve body has valve pocket, valve gap is fixed on the valve body, valve seat is fixedly mounted in the valve body, in valve body, be installed with guide sleeve, valve rod is installed in slipper seal in valve gap, stem bottom fixed installation spool, spool and guide sleeve are slidingly connected, it is characterized in that: said valve seat is ceramic valve seat, and the fluid output vias inner walls of valve body is installed ceramic Taper Pipe, and ceramic Taper Pipe is fixedly mounted in the valve body by trim ring and fastening screw trip bolt.
Described ceramic valve seat and ceramic Taper Pipe are zirconia-based ceramics, alumina-based ceramic, types of silicon carbide-based ceramics, mullite-based ceramic or silicon-nitride-based ceramic.
Advantage of the present utility model and beneficial effect are:
Because valve seat adopts the bulk ceramics material to make, and has greatly prolonged the working life of valve seat, valve outlet runner lining ceramic wear-resisting pipeline greatly reduces medium to the erosion of pipeline, has prolonged the working life of valve.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
Wherein: 1-valve body, 2-valve gap, 3-valve seat, 4-guide sleeve, 5-valve rod, 6-spool, 7-fastening screw trip bolt, 8-pottery Taper Pipe, 9-trim ring.
Embodiment
Below in conjunction with concrete drawings and Examples the utility model is further specified.
Embodiment: as shown in the figure, a kind of wear-resistant ceramic high-pressure angle valve, valve body 1 has valve pocket, valve gap 2 is fixed on the valve body 1, valve seat 3 is fixedly mounted in the valve body 1, in valve body 1, be installed with guide sleeve 4, in valve gap 2 interior slipper seals valve rod 5 is installed, valve rod 5 bottoms fixed installation spool 6, spool 6 is slidingly connected with guide sleeve 4, said valve seat 3 is ceramic valve seat, can avoid so the too fast damage of valve seat 3, prolongs the working life of valve seat 3, the fluid output vias inner walls of valve body 1 is installed ceramic Taper Pipe 8, avoided the erosion of abrasiveness medium to metal flow passage, greatly improved the working life of valve, ceramic Taper Pipe 8 is fixedly mounted in the valve body 1 by trim ring 9 and fastening screw trip bolt 7.
