Abstract
The utility model discloses the sealing configuration on stop valve, comprise valve rod, valve disc, soft seal pad, bolt and spacer, described valve rod is vertically fixed on valve disc, at the central position weld bolt of valve disc bottom, on bolt, also successively through spacer, soft seal pad and gland nut, spacer is close to valve disc bottom; Described soft seal pad size and the equal and opposite in direction of valve disc.The utility model passes through said structure, can not exert an influence to the velocity of medium of valve flowing channel, sealing result is good, it is convenient to repair, cost-saving, even if impaired is suitable for, and can change to the material of sealing configuration, intensity, structure organization etc. more too, be more conducive to later stage continuation and use.
Description
Technical field
The utility model relates to valve field, particularly, relates to the sealing configuration on stop valve.
Background technique
On current valve uses, the most general problem is exactly Strength Failure and the seal failure of valve.There are following two kinds for the factor that affects valve sealing structure design nowadays relating to, a kind of is the seal element that sealing configuration has comprised complex characteristics, another kind is the unsteady phenomena that in working state, sealing configuration runs into, as temperature, sealing medium characteristic and pressure etc.The valve disc of the stop valve nowadays using, the inner sealing surface of valve seat are hard sealed types, after sealing effect lost efficacy, repair if send manufacturer back to, and cost is higher.And in general daily life, the restorative procedure of the damage of valve sealing structure comprises following two kinds, a kind of is to utilize grinding stone or sand paper to add appropriate lapping paste to grind broken parts simultaneously, but is only applicable to impaired less sealing configuration; Another kind is, on lathe, the seal element of damaged is carried out to turning processing, its shortcoming be expend time in long and repair after the aspect such as material, intensity, structure organization of Sealing all change, be unfavorable for that the continuation in later stage is used.
Model utility content
Technical problem to be solved in the utility model is to provide the sealing configuration on a kind of stop valve, this structure can not exert an influence to the velocity of medium of valve flowing channel, sealing result is good, it is convenient to repair, cost-saving, even if impaired is suitable for, and can change to the material of sealing configuration, intensity, structure organization etc. more too, be more conducive to later stage continuation and use.
The technical scheme in the invention for solving the above technical problem is: the sealing configuration on stop valve, comprise valve rod, valve disc, soft seal pad, bolt and spacer, described valve rod is vertically fixed on valve disc, at the central position weld bolt of valve disc bottom, on bolt, also successively through spacer, soft seal pad and gland nut, spacer is close to valve disc bottom; Described soft seal pad size and the equal and opposite in direction of valve disc.The sealing surface of soft sealing gasket and hard valve seat forms the mating face of sealing, and from improving, the hard sealing surface of rigidity becomes the sealing surface that soft or hard engages, and has increased the area of sealing, fits tightr, and sealing effect is better, even if impaired is suitable for more too.In the time again there is interior leakage situation in valve, only the soft seal pad of wearing and tearing need be changed and just can be completed reparation, cost-saving, it is convenient to repair, and can not change to the material of sealing configuration, intensity, structure organization etc., is more conducive to later stage continuation and uses.This kind of structure used in valve, in the time that the sealing surface of valve seat produces less degree of impairment, can be utilized regulating valve screw mandrel open degree that soft sealing gasket is compressed, reach the effect of sealing, easy to use.
The length range of described bolt is between 1-2cm.Weld bolt, within the scope of this, avoids occurring that bolt is long and propped up the inner flow passage of valve body, forms the built on stilts situation of sealing surface, and the soft seal pad that impact is enclosed within on bolt is brought into play its seal action.
Described spacer is square structure, and the thickness of spacer is less than or equal to valve disc and soft seal mat thickness sum.The thickness of spacer is positioned at this scope, so that the sealing surface of soft seal pad and valve disc can fit tightly, reaches better sealing effect.
Described soft seal pad is teflon or rubber plate sealing gasket.This kind of sealing gasket good sealing effect, not fragile.
Described valve rod and bolt are located along the same line and all perpendicular to valve disc.
Fastening piece is also set between described valve rod and valve disc.
To sum up, the beneficial effects of the utility model are:
1, the sealing surface of soft sealing gasket and hard valve seat forms the mating face of sealing, from improving, the hard sealing surface of rigidity becomes the sealing surface that soft or hard engages, and increase the area of sealing, fit tightr, sealing effect is better, even if impaired is suitable for more too, cost-saving, it is convenient to repair, and can not change to the material of sealing configuration, intensity, structure organization etc., is more conducive to later stage continuation and uses.
2, the length range of bolt is between 1-2cm, avoids occurring that bolt is long and propped up the inner flow passage of valve body, forms the built on stilts situation of sealing surface, and the soft seal pad that impact is enclosed within on bolt is brought into play its seal action.
3, the thickness of spacer is less than or equal to valve disc and soft seal mat thickness sum, so that the sealing surface of soft seal pad and valve disc can fit tightly, reaches better sealing effect.
