Abstract
The utility model discloses a dusty gas butterfly valve comprising a valve rod, a valve body and a butterfly plate. The butterfly plate is circular, and a linkage rib is arranged a one-side surface through fixing blocks. The valve rod is arranged on the valve body. The linkage rib is fixed with the lower end of the valve rod penetrating the valve body, and a wear-resistant layer is arranged on the outer ring of the butterfly plate. The valve is low in opening and closing resistance, anti-sticking, wear-resistant, corrosion-resistant, widely applicable, long in service life and lower in using cost.
Description
Technical field
The utility model relates to valve, relates in particular to a kind of dust and gas butterfly valve.
Background technique
Traditional dust and gas butterfly valve is widely used in ventilating and purifying air system, to dust-containing airflow, gas pipe line, ventilated purification apparatus, fume pipe etc. as Flow-rate adjustment and the use of damming, use amount is large, loss is large, butterfly plate is due to dust deposit, can increase valve opening and closing resistance, increase wearing and tearing, have a strong impact on normal keying; Increased useless damage, often changed very inconveniently, cost is also high.
Model utility content
According to above-mentioned situation, the purpose of this utility model is to provide a kind of dust and gas butterfly valve.
The utility model takes following technological scheme to realize:
A kind of dust and gas butterfly valve, comprises valve rod, valve body and butterfly plate, and described butterfly plate is circular, in single side surface, is fixed with interlock muscle by fixed block; Described valve rod is arranged on valve body; Described interlock muscle and through the valve rod lower end of valve body fixing; On the outer ring of described butterfly plate, be provided with wearing layer.
Described wearing layer adopts aluminium oxide ceramics sheet material.
The width of described wearing layer is 0.2-0.5mm.
The utlity model has in sum following beneficial effect: the utility model valve opening and closing resistance is little, antiseized sticky, wear-resistant, corrosion-resistant, can be widely used, long service life, has reduced user cost.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Wherein: 1, valve rod; 2, valve body; 3, wearing layer; 4, butterfly plate; 5, interlock muscle; 6, fixed block.
Embodiment
