Abstract
The utility model provides a stainless steel is very stiff and demanding butterfly valve at many levels, including transmission and butterfly valve body, the butterfly valve body includes the support, and support one end is provided with the valve body, is equipped with the packing cavity in the valve body, is equipped with gland on the packing cavity, still is equipped with the axle sleeve between valve body and the support, valve body and butterfly plate between be equipped with the butterfly plate sealing washer, the valve body other end is equipped with the sealing washer clamp plate, the sealing washer clamp plate is fixed the butterfly plate on the valve rod, the valve body corresponds the other end of going up the axle sleeve and still is equipped with down the axle sleeve, is equipped with down the gland on the lower axle sleeve, lower gland and descend still to be equipped with the divided ring between the axle sleeve, the beneficial effect of the utility model: multi -level elasticity sealing washer on this product butterfly plate is superposeed to suppress by nonrust steel sheet one deck to form each other, advises stainless steel stone -clamping china ink to compare with ordinary multi -level butterfly valve wood, not only has good hardness and better anti friction properties, have to have fine anti high temperature high pressure performance and prevent fires to be able to bear or endure to wash away the function, and long service life, the cost of manufacture is low.
Description
Technical field
The utility model relates to valve field, particularly a kind of stainless steel multilayer time very stiff and demanding butterfly valve.
Background technique
Now multi-level butterfly valve hardness is commercially low, friction resistant poor performance, high temperature resistance high-voltage performance and fire prevention flushing resistance all very poor, working life is short, and cost is high, so need a kind of stainless steel multilayer time very stiff and demanding butterfly valve just can address these problems.
For existing technical deficiency, the utility model provides a kind of stainless steel multilayer time very stiff and demanding butterfly valve.
To achieve these goals, technical solution adopted in the utility model is: stainless steel multilayer time very stiff and demanding butterfly valve, comprise transmission device and butterfly valve body, butterfly valve body comprises support, support one end is provided with valve body, packing cavity is provided with in valve body, packing cavity is provided with Gland, also Upper shaft sleeve is provided with between valve body and support, butterfly plate seal ring is provided with between described valve body and butterfly plate, the valve body the other end is provided with seal ring pressing plate, butterfly plate is fixed on valve rod by seal ring pressing plate, the other end of the corresponding Upper shaft sleeve of valve body is also provided with Lower shaft sleeve, Lower shaft sleeve is provided with lower cover, also divided ring is provided with between lower cover and Lower shaft sleeve.
Described butterfly valve seal circle superposes compacting by some layers of stainless steel sheets and forms.
Described transmission device is driver.
Expanded graphite is filled with in described packing cavity.
The beneficial effects of the utility model: the multi-level elastic seal ring on this product butterfly plate in layer mutually superposes compacting by stainless steel sheets to form, compared with advising stainless steel horsestone ink with common multi-level butterfly valve wood, not only there is good hardness and good friction resistant performance, have and there is good high temperature resistance high-voltage performance and fire prevention resistance to erosion function, long service life, fabricating cost is low.
