Description
Technical field
This utility model relates to stop valve field, is specifically related to a kind of supercritical small-bore corrugated tube ball face sealing forging and cuts
Only valve.
Background technology
The stop valve of current domestic employing all also exists the shortcomings such as manufacture requirements is high, easily leak, service life is short.Ripple
Pipe stop valve has reasonably sealing structure and decay resistance, and service life is long, and maintenance frequency is few, reduces operating cost.Hard
Gu durable sylphon seal design, it is ensured that the zero leakage of valve rod, it is provided that the condition of Maintenance free.Valve opening and closing moment is little, subtracts
Little labor intensity.The external seal of valve uses sylphon seal and graphite, stainless steel ring to seal, and seals reliable, and permanent use can
Airtight and watertight padding need not be changed.Design and manufacture strictly use foreign advanced standard.
Corrugated tube ball face sealing forging stop valve, aesthetic in appearance, valve passage has the streamline of smoothness, reduces the stream of valve
Resistance coefficient, is a kind of high-quality energy-conserving product.
Summary of the invention
In order to solve the problems referred to above, the utility model proposes a kind of supercritical small-bore corrugated tube ball face sealing forging and cut
Only valve, designs ingenious, easy to use, solves the valve short technical problem using temperature with raising valve in service life, meets and make
Use operating mode.
In order to reach foregoing invention purpose, the utility model proposes techniques below scheme:
Supercritical small-bore corrugated tube ball face sealing forging stop valve, valve body, ball sealer, sealing ring, valve rod, corrugated tube,
Valve gap, Packing seat, filler, gland, pressing plate, support, valve stem nut, handwheel, equipped with ball sealer in the middle of valve body, ball sealer and valve body
Between be designed with valve seat, ball sealer upper end connects valve rod, and valve body upper end is equipped with valve gap, equipped with sealing ring between valve gap and valve body,
Valve gap upper end connects support, equipped with corrugated tube between valve rod and valve gap, is sequentially arranged with Packing seat, filler between support and valve rod,
Filler is pressed on Packing seat, is pressed with gland above filler, and gland upper end is pressed with pressing plate, and pressing plate both sides are fixed on support both sides, valve
Bar upper end is equipped with valve stem nut, and equipped with handwheel on valve stem nut, handwheel is locked at valve stem nut upper end by locking nut.
Described valve rod and ball sealer are integral production molding.
The import of described valve body has pipe socket joint song and welds annular groove with outlet.
Described sealing ring is hard sealing, uses F316 rustless steel to make molding.
Described valve seat and one layer of STL hard alloy of sealing surface weld deposit of ball sealer.
Described pressing plate both sides are fixed on support both sides by eyelet bolt, straight pin, nut, and eyelet bolt lower end is passed through
Straight pin is fixed on support, and nut check is passed through after running through pressing plate in eyelet bolt upper end.
The utility model has the advantages that structure is different: former valve rod separates with flap, is now monoblock type.Former flap is that the conical surface is close
Envelope, now changes ball face sealing, automatic centering, it is not easy to leakage.Use temperature: former less than 350 degree, be now 600 degree.Use pressure:
Former below 600LB, is now 1500LB.Valve rod uses fine pitch screw-driven, can realize regulating flow trace.Seal: former soft
Seal (middle head gasket), existing for hard sealing (F316 rustless steel).
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
