The invention discloses a clamp-connecting
globe valve of a corrugated tube, relating to a
globe valve. The clamp-connecting
globe valve comprises a clamp-connecting valve body; Co-based cemented-
carbide sealing ring is welded on the valve body in a resurfacing manner; a double corrugated tube device coated with austenitic
titanium stainless steel is detachably and mechanically connected to the lower part of a
valve stem; and when a hand-wheel is turned, a lifting poker of the
valve stem drives the double corrugated tube device coated with austenitic
titanium stainless steel to rise and fall through a
valve stem nut. The strong durable double corrugated tube is convenient to detach, a
clamp connection is also convenient to detach, a product is simple in structure and reliable in sealing, and zero leakage of the valve stem is guaranteed. The clamp-connecting globe valve has no fluid loss, reduces
energy loss and increases safety to the
plant equipment. The sealing surface is welded with Co-based
cemented carbide in a surfacing manner; the corrugated tube is coated with austenitic
titanium stainless steel, thereby being wear-proof and
corrosion-poof and having good anti-friction performance and long service life; the clamp-connecting globe valve is applicable to
engineering pipelines with clamp-connecting nut externally connecting a conduit under various
engineering conditions in
petroleum industry,
chemistry industry,
pharmacy industry,
fertilizer industry,
electricity industry and the like to
cut off or connect the pipeline media, particularly to the
engineering of a heat-conducting oil boiler pipeline.
