Abstract
The invention relates to a large-caliber ultrathin metallic oxide throttle valve, which is formed by a flashboard, a valve body and a metallic oxide ceramic ring, wherein the valve body is embedded in the flashboard; raised grains are adopted on the periphery of the valve body; a circle of the metallic oxide ceramic ring is also arranged in the valve body; and a structure of the metallic oxide ceramic ring and the valve adopt wave shapes correspondingly. Due to the adoption of the metallic oxide ceramic ring, the abrasion resistance of the valve body can be effectively increased, and the service life of the valve body is greatly prolonged. The large-caliber ultrathin metallic oxide throttle valve has a simple structure and strong practicability, and is suitable to be popularized widely.
Description
Technical field
The present invention relates to washed coal and use valve field, particularly relate to a kind of heavy caliber ultra-thin metal oxide throttle valve.
Background technique
Weight, length of installation bulk to the large bore valves installed on the major diameter suspended piping of large-scale washing coal works all have strict restriction; Therefore the ultra-thin valve of heavy caliber is used widely in large-scale coal washery; Its feature is that lifting and easy to maintenance is installed; Little to unsettled large-diameter pipeline load, installation dimension is little.Although but these valves that use have now reached on overall weight, installing space and pipeline load and have selected requirement for use; But the ubiquity wear-resisting property is poor; Life-span is short; Mean lifetime about 60 days, change valve cause stoppings production, residual medium leak outside to the washing coal works normal produce to have brought seriously influence, so to develop the ultra-thin valve of this series long lifetime heavy caliber be a very important job in the clean coal technology engineering.
Select for use the high abrasion metal oxide ceramic as the overcurrent of valve and the material of closure member; On middle-size and small-size wear-resisting ultra-thin valve, obtained successful development Experience; But on this type of ultra-thin large bore valves, using also is a blank; This is to be very easy to distortion when installing on pipeline because of the ultra-thin valve of heavy caliber; Therefore to requirement ultra middle the smaller diameter valve far away of the fracture toughness of the metal oxide ceramic material selected for use, two technical parameters of thermal shock resistance use the material requirement, have the design error very easily to cause the breakage of this wear-resistant ceramic material slightly and then cause the damage of this large bore valves integral body;
The metal oxide ceramic material is very big in the ultra-thin valve cavity occupation space of heavy caliber; And valve thickness size " ultra-thin " restriction; Valve integral rigidity can significantly decrease, to such an extent as to therefore must solve valve under the constant prerequisite of installation volume because the difficult problem that distortion that fastening and large diameter pipeline STRESS VARIATION at work brings valve destroys the metal oxide ceramic material of the high abrasion of installing in the valve is installed.
Summary of the invention
Technical problem to be solved by this invention provides a kind of heavy caliber ultra-thin metal oxide throttle valve, can effectively increase the life-span and the abrasion resistance of valve.
The technological scheme that problem adopted that the present invention will solve is: a kind of heavy caliber ultra-thin metal oxide throttle valve; Form by flashboard, valve body, metal oxide ceramic ring; Valve body is embedded in the flashboard; Adopt ripple glaze around the valve body, a circle metal oxide ceramic ring also is installed, the corresponding employing waveform of metal oxide ceramic ring structure in flashboard with valve body.
Beneficial effect of the present invention is: employing metal oxide ceramic ring can effectively increase the abrasion resistance of valve body, prolongs the working life of valve body greatly, and the present invention adopts simple in structure, and is practical, is fit to extensively promote.
