Description
Technical field
The utility model relates to a kind of light moment and opens a sluice gate soon valve stem structure.
Background technique
The seal failure of tradition gate valve rod produces and leaks is to affect one of gate valve working life and extensive popularization problem, particularly requires the operating mode of zero leakage, limits especially its using scope.The sealing of valve rod is the squeezing action of utilizing between filler and valve rod, makes filler step up valve rod, dwindles that distance between valve rod and filler realizes.Long service time when valve, filling property changes, and filler wearing and tearing or filler pretightening force are inadequate, and distance gap between valve rod and filler is increased, and will affect the sealing effect of stuffing box, and generation leaks outside.Meanwhile, traditional gate valve, along with the increase of size and pressure, opens and closes moment and also just increases thereupon, in some special operation condition fields, while opening and closing valve as need are emergent, realize fast opening and closing, often cannot reach the effect of anticipation, open and close moment excessive, torsion is overweight, opens more difficultly, and labor intensity is larger.
Summary of the invention
For the defect of above-mentioned gate valve, the utility model provides a kind of light moment to open a sluice gate soon valve stem structure.
For achieving the above object, the measure that the utility model is taked is: the utility model provides a kind of light moment to open a sluice gate soon valve stem structure, one-part form secondary four-head screw thread fast opening and closing screw rod, the light moment labor-saving structure of screw rod, the tight upside-down mounting sealing configuration in middle part and four kinds of structures of handwheel labour-saving device, consists of.
One-part form secondary four-head screw thread fast opening and closing screw rod, by one section of single head triangle screw rod and one section of external four-head trapezoidal thread sleeve pipe, formed, single head triangle screw rod is full-scale, external four-head trapezoidal thread casing length is half of single head triangle screw rod, and the middle flashboard supporting with it equates with external four-head trapezoidal thread casing length size.
/ 2nd positions, single head triangle screw rod lower end are v thread district, in external four-head trapezoidal thread sleeve pipe, logical position arranges and the supporting v thread screw thread of tightening of single head triangle screw rod, and middle flashboard middle part arranges the four-head trapezoidal thread screw thread supporting with external four-head trapezoidal thread sleeve pipe four-head trapezoidal thread.
Single head triangle screw rod is arranged with the supporting v thread screw thread of tightening of single head triangle screw rod and is tightened and form an one-part form secondary four-head screw thread fast opening and closing screw rod by logical position in external four-head trapezoidal thread sleeve pipe.
The light moment labor-saving structure of screw rod, is comprised of one-part form secondary four-head screw thread fast opening and closing screw rod, thrust ball bearing, bearing cap, bearing gland and valve gap neck middle part.
One-part form secondary four-head screw thread fast opening and closing screw rod, top arranges and is connected groove with upper valve rod, in groove plane and lower end position setting and the supporting v thread being connected of bearing cap middle part.Meanwhile, in groove plane and v thread lower end, thrust ball bearing positioning step is set.Described bearing cap middle part arrange v thread screw thread and are connected fastening with secondary four-head screw thread fast opening and closing screw tip, and are connected the unidimensional in the same way supporting groove of groove with upper valve rod at bearing cap upper end.
Bearing gland outer installment v thread, valve gap neck middle part arranges thrust ball bearing limited step, and arranges and the supporting v thread screw thread being connected of bearing gland in limited step bottom.Thrust ball bearing is arranged on upper valve rod and is connected groove lower end, the thrust ball bearing positioning step arranging on one-part form secondary four-head screw thread fast opening and closing screw rod location, and by bearing cap, the fixing rank of thrust ball bearing is tight.Formation is with the one-part form secondary four-head screw thread fast opening and closing screw rod of thrust ball bearing.
The tight upside-down mounting sealing configuration in middle part and handwheel labour-saving device are comprised of upper valve rod, valve gap neck middle part, filler, rolling bearing, handwheel, butterfly shell fragment and nut.
Upper valve rod bottom arranges filler positioning boss, and valve gap neck middle part arranges filler positioning step.Upper valve rod bottom arranges on filler positioning boss plane and with valve gap neck middle part, filler positioning step plane symmetry is set and distributes, size equalization.Valve gap neck middle part adopts integrally casting, at medium position, filler positioning step is set.The bottom processing puts filler with the upper valve rod of filler positioning boss, and filler can be determined according to work condition environment, and general low temperature environment adopts tetrafluoro polyethylene, and high temperature adopts metal to add graphite and makes filler.
At valve gap neck top, middle part and handwheel contact position, the medium position of placing along upper valve rod arranges rolling bearing positioning groove.When upper valve rod filler together upside-down mounting enters valve gap neck middle part, filler is by being attached on positioning boss and positioning step.
In rolling bearing placement positioning groove.Then, handwheel, butterfly shell fragment are assemblied in successively on the upper valve rod top and rolling bearing of upside-down mounting sealing, with nut, on the upper valve rod of upside-down mounting sealing, tighten.
After tightening on the upper valve rod of upside-down mounting sealing, again the one-part form secondary four-head screw thread fast opening and closing screw rod upside-down mounting with thrust ball bearing is entered to valve gap neck middle part, make supporting connection of linking groove of convex shoulder that upper valve rod bottom filling positioning boss bottom arranges and one-part form secondary four-head screw thread fast opening and closing screw tip setting with thrust ball bearing.Thrust ball bearing valve gap neck middle part arrange thrust ball bearing limited step be fixed spacing, by bearing gland by arranging and the supporting v thread screw thread being connected of bearing gland in limited step bottom, with the fixing rank in valve gap neck middle part tightly.Realize the feature of the light moment Quick-opening valve rod structure of gate valve completely.
the beneficial effects of the utility model: the utility model can be realized the rapidly opened and closed function of valve by one-part form secondary four-head screw thread fast opening and closing screw-rod structure; The light moment labor-saving structure of screw rod, handwheel labour-saving device can be realized light moment function when opening and closing, and realize switching laborsaving; Middle part is upside-down mounting sealing configuration closely, makes valve central structure and sealing tightr, simultaneously, by this kind of design, broken traditional gate valve completely, by size, increase the drawback that increase relatively at valve gap neck middle part, realized and reduced valve gap neck middle part size, saved the complexity of raw material and processing.By the appropriate design of above four kinds of structures, the utility model product, in whole manufacture cost, can not surpass similar gate valve product, and physical life can improve decades of times, be conducive to allow traditional gate valve update, this product is by the compensation sealing of upside-down mounting sealing and butterfly shell fragment, can make valve extend 30-50 working life.One-part form secondary four-head screw thread fast opening and closing screw-rod structure, the light moment labor-saving structure of screw rod and handwheel labour-saving device, can realize rapidly opened and closed, have laborsaving simultaneously, reduce labor intensity, the type design valve performance improves greatly, operator's labor intensity alleviates more than 60%, and operating effect is obvious.In special work condition environment, open soon function and more there is safety reliability.
