Background technique
Along with the develop rapidly of information technology and industrial intelligent improve constantly, valve is as the end effector controlling fluid motion in pipeline, just progressively change the narrow limitation of ego function and be imbued with brand-new theory, and inner valve enterprise of state is just along energy-saving and environmental protection, the new demand new direction development such as intelligence, volume are little, lightweight, the life-span is long.
Traditional valve comprises ball valve and stopcock, and ball valve exists following shortcoming:
1, because spool is sphere structure, because this increasing difficulty of processing, must process with special device, improve cost of production, reducing work efficiency.
2, owing to adopting seal ring sealing, if therefore spool and sealing seat sealing surface with face seal will moment of torsion very large, can only linear sealing, the little sealability that causes of linear sealing surface of contact is poor, causes ball valve to occur interior leakage, more outstanding during low-pressure state.
3, the moment of torsion of ball valve is comparatively large, therefore easily causes valve rod to be out of shape or twists off and the acceleration of sealing seat fatigue.
And the shortcoming of stopcock is as follows:
1, because spool is cone structure, therefore after spool moves up and down, easily cause between spool and sealing seat and produce gap damage, reduce sealing effect.
2, owing to adopting spool crush seal seat to realize sealing, therefore sealing effect is poor.
Model utility content
For the defect existed in prior art, the purpose of this utility model be to provide a kind of there is quadrant tubular spool revolve a valve, the utility model is easy to processing, and without the need to special device, material is commercially directly bought, and reduces cost of production; Seal form is face sealing, adds valve base sealing area, improves manufacturing efficiency and sealing effect, can extend valve and reduce cost of production working life.
For reaching above object, the technological scheme that the utility model is taked is: a kind of there is quadrant tubular spool revolve a valve, comprise valve body, drive unit, quadrant tubular spool and sealing seat; Be provided with valve cavity in described valve body, the both sides of valve cavity are communicated with an entrance sleeve and a discharge connection respectively; The top of valve body is provided with mounting hole; Described quadrant tubular spool is inserted in valve cavity by mounting hole, and the end face of quadrant tubular spool and bottom surface are fan-shaped, the drift angle place of end face connects the upper valve rod that is stretched out mounting hole, and upper valve rod connects the drive unit driving its axial rotation; Described sealing seat is shape of a saddle circle structure, between the outer side wall being arranged on quadrant tubular spool and entrance sleeve.
On the basis of technique scheme, one end that described sealing seat contacts with quadrant tubular spool is for seal curved surface, and its external frame is the shape of a saddle caved inward, and fits tightly with quadrant tubular spool outer surface; The annulus through hole of sealing seat is communicated with entrance sleeve.
On the basis of technique scheme, described mounting hole top is provided with valve gap, and valve gap is provided with the through hole passed for upper valve rod, and is filled with filler between through hole and upper valve rod.
On the basis of technique scheme, the bottom of described valve gap is provided with layer of metal pad.
On the basis of technique scheme, also comprise lower valve rod, the drift angle place of described quadrant tubular spool bottom surface is by the bottom surface pivot joint of lower valve rod and valve body.
On the basis of technique scheme, described drive unit is pneumatic actuator, electric actuator, hydraulic executer or manual turbine.
On the basis of technique scheme, described quadrant tubular spool, sealing seat all adopt stainless steel to make.
The beneficial effects of the utility model are:
1, in the utility model, adopt quadrant tubular spool, be easy to processing compared to ball valve core, reduce cost of production.
2, in the utility model, sealing seat is shape of a saddle circle structure, and can match with the outer surface of quadrant tubular spool formation sealing surface, adds sealing area; In addition, when quadrant tubular spool moves up and down, sealing seat still can keep sealing state with quadrant tubular spool, improves sealing effect.
3, in the utility model, the moment of torsion of quadrant tubular spool is less, therefore avoid valve rod twist off and sealing seat fatigue problem produce.
4, in the utility model, owing to adopting quadrant tubular spool and be provided with mounting hole, after quadrant tubular spool or sealing seat wearing and tearing, can quick-replaceable, improve manufacturing efficiency.
5, in the utility model, owing to adopting quadrant tubular spool, its materials are only 1/4th of cylindrical shape spool, and only need a sealing seat to be mated work, because this reducing cost of production.
