Description
Technical field
The present invention relates to a kind of ball valve, particularly a kind of upper dress formula fixing ball valve, belongs to valve technology field.
Background technique
Ball valve is widely used in the every field such as oil, chemical industry, iron and steel, metallurgy and electric power, and with respect to the valve of other control valve track media circulations, ball valve has the advantages such as resistance of medium is little, easy to operate.But, because PTEF is because its compression strength is low, in the time exceeding its compression strength, produces cold flow and make rebound elasticity variation, this phenomenon causes material in the above pressure rating of 300Lb, or 300Lb size is 12 " to be difficult to application in upper ball valve.And nylon, polyether-ether-ketone resin are widely used in the above pressure rating of 30Lb with its very high compression strength, or 300Lb size is 12 " more than ball valve in; but because it exceedes the above friction factor of 10 times of teflon, the operation moment of torsion of ball valve is improved significantly.Two of tradition or the side-mounted fixing ball valve of three pieces type split limit to because of structure, and valve body lumen uses bolt to connect, and leak point is many, and assembling is safeguarded loaded down with trivial details, limits its on-line maintenance function, increases stopping production risk.Side-mounted fixing ball valve is in the time breaking down maintenance, and whole valve must cut down from pipeline, causes the relevant tube line length time to be stopped and stops production, and causes heavy economic losses.
