Description
Technical field
The present invention relates to conduit fittings technical field, relate in particular a kind of two scraper diaphragm butterfly valve.
Background technology
Existing butterfly valve, as centre-pivoted butterfly valve, is from metal valve body, to embed rubber sleeve to form again, byBetween butterfly plate rotate crush seal, it is narrow that butterfly plate and the extruding of rubber sleeve contact sealing area, do not press againPower self sealing action, so it is low to bear sealing load, often crush seal is also easily damaged, becauseAdopt overall rubber-lined cover, the material of gum cover used is many, and cost is too high, and elastomeric material used is easily oldChange, so the general sealing load of centre-pivoted butterfly valve is low, service life is short, and for example eccentric-butterfly-valve, employingEccentric sealed structure, has used the track rule of eccentric butterfly plate in rotating distance, is provided with corresponding positionPut valve seat and be close to sealing, because valve seat and butterfly plate are the fixed sealings of being close to, there is no too large elasticityCompensation or other by thrust, the sealing surface contact area producing is also smaller, so sealing load is alsoCan be too not high, in pipeline medium, slightly impurity folder is clipped on sealing surface, is easy to cause leakage, andMore leakage is larger, and use state is not ideal, and difficulty of processing is also large. Existing butterfly valve four directions cylindricality upper valve rodAnd between butterfly plate, make and be cylindrically connected with pin, between cylindrical lower valve rod and butterfly plate, be connected with pin, timeBetween the long aging disconnection of pin, can cause valve rod and butterfly plate to depart from out of control.
How therefore a kind of butterfly valve with dependable performance, long service life, the low feature of cost be provided is thisThose skilled in the art need the problem of solution badly.
Summary of the invention
