Abstract
The utility model discloses a high-temperature-resistant abrasion-resistant butterfly valve, belongs to the mechanical field, and particularly provides the high-temperature-resistant abrasion-resistant butterfly valve which is simple in structure and convenient to use. The high-temperature-resistant abrasion-resistant butterfly valve comprises two concentric annular side plates, a valve cavity is arranged in the middle of the two annular side plates, and a valve plate which is connected with a rotary device is arranged in the valve cavity. The high-temperature-resistant abrasion-resistant butterfly valve is structurally characterized in that a heat-isolating sleeve corresponding to the valve cavity is disposed between the two annular side plates, the heat-isolating sleeve comprises an outer sleeve body connected with opposite sides of the two annular side plates and an inner sleeve body concentric with the outer sleeve, and a cavity is formed between the outer sleeve and the inner sleeve. The surface of the valve plate is wrapped by an alumina ceramic layer.
Description
Technical field
The utility model belongs to mechanical field, and the utility model relates to a kind of improvement of butterfly valve structure specifically.
Background technique
Butterfly valve, simple in structure with it, easy to use, be widely used at present in the various fields; When for fields such as chemical industry, medicine, military project, metallurgy, medium temperature requires to reach more than 800 ℃, even 1000 ℃.For guaranteeing the working life of valve body, need carry out water-cooled to whole valve body usually.
After existing high temperature resistant butterfly valve uses water-cooled, easily produce dirt, and, when water-cooled can make High temperature valve meet cooling water, produce a large amount of high-temperature steams; In case high-temperature steam is dredged when going wrong, the phenomenon of can blasting causes serious production safety accident.In addition, cooling water also can be taken away a large amount of heats, causes energy waste.
In addition, existing metal valve plate is in the very easily wearing and tearing of washing away for a long time down of high temperature media; Can cause butterfly valve low problem in working life.
Summary of the invention
The utility model is exactly at the problems referred to above, provides a kind of simple in structure, the high temperature resistant butterfly valve that resistance to wears easy to use.
For realizing above-mentioned purpose of the present utility model, adopt following technological scheme, the utility model comprises two concentric annular side plate, the center of two annular side plate is valve pocket, be provided with the valve plate that links to each other with slewing gear in the valve pocket, be provided with collet corresponding to valve pocket between its structure outline institute two annular side plate, described collet comprises the overcoat that links to each other with the relative side of two annular side plate and the interior cover concentric with overcoat, is cavity between overcoat and the interior cover; Described valve plate surface coverage is provided with the aluminium oxide ceramics layer.
As a kind of preferred version of the present utility model, in the cavity of described collet centered by the center of circle of valve pocket the radial stiffening plate that is provided with.
As another kind of preferred version of the present utility model, be provided with the connecting plate that connects two annular cage plates and overcoat between described two annular side plate.
The beneficial effects of the utility model:
1, the utility model is simple in structure, and production and processing is convenient.
2, the utility model makes and passes through cavity isolation between valve pocket and the whole valve body by the collet structure, makes the temperature of high temperature media in the valve pocket be difficult for outwards transmitting, and has improved heat-resisting ability of the present utility model.
3, the utility model is undertaken heat insulationly by collet, need not water-cooled, in the time of simplified structure, and the energy of taking away when also saving water-cooled; And do not have the generation of water vapour, stopped the potential safety hazard of blast.
4, the utility model has increased the intensity of collet by stiffening plate, has increased the intensity of two annular side plate by connecting plate, has improved working life of the present utility model.
5, the utility model is provided with the aluminium oxide ceramics layer on the valve plate surface, reaches the high temperature resistance and wearing resistance effect.
