Abstract
The utility model discloses a metal hard sealing V-type cut ball valve which comprises an upper valve body (1) which is longitudinally arranged and a lower valve body (3) which is transversely arranged. An upper valve rod (2) is arranged in the upper valve body (1), the lower end of the upper valve rod (2) is connected with a cut type ball surface valve plate (10) in the lower valve body (3), a hard valve base component and a pressing valve component (4) are sequentially arranged at the left end of the cut type ball surface valve plate (10), and the lower end of the cut type ball surface valve plate (10) is connected with a flange (12) arranged at the bottom of the lower valve body (3) through a lower valve rod (11). The valve plate of the ball valve is arranged to be of a cut type structure, in the closure process, the shearing effect on a sealing ring is achieved, and therefore the sealing performance is better, and the control precision is higher.
Description
Technical field
The utility model relates to a kind of metal hard seal V-type otch ball valve.
Background technique
At present, the sealing effect of the spheroid of conventional ball valve in the time damming is poor, and control accuracy is low, is not suitable for regulating greatly the system of ratio.In addition, traditional ball valve fixes to clamp sealing with a valve seat respectively at the two ends of spheroid, while causing valve opening, torsion is large, adopt filler pressing sleeve to oppress by force filler and make valve stem seal, filler is fragile like this, and spheroid groove employing arc groove, sealing effect is poor, and in groove, easily has residual difficult cleaning of material.
Model utility content
The utility model object is that the defect existing for prior art provides a kind of metal hard seal V-type otch ball valve.
The utility model for achieving the above object, adopt following technological scheme: metal hard seal V-type otch ball valve, comprise the upper valve body of longitudinal layout and the lower valve body of lateral arrangement, in described upper valve body, be provided with upper valve rod, the lower end of described upper valve rod is connected with the notch shape sphere valve plate being arranged in described lower valve body; The left end of described notch shape sphere valve plate is disposed with hard valve component and pressure valve assembly, and the lower end of described notch shape sphere valve plate is connected with the flange that is arranged on lower valve body bottom by lower valve rod.
Further, be evenly provided with filler and filler dividing plate in the activity space between described upper valve rod and described upper valve body, the upper-end surface of described upper valve body is disposed with Gland and hold-down grid.
The beneficial effects of the utility model: the valve plate setting of ball valve of the present utility model is the structure of notch shape, it also has shear action to seal ring in the time damming, therefore its better tightness, control accuracy is higher.Therefore be relatively applicable to regulate greatly the system of ratio, and to obviously excellent and other modulating valve of the control of cellulosic, slip class fluid.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Shown in Fig. 1, for a kind of metal hard seal V-type otch ball valve, comprise the upper valve body 1 of longitudinal layout and the lower valve body 3 of lateral arrangement, in described upper valve body 1, be provided with upper valve rod 2, the lower end of described upper valve rod 2 is connected with the notch shape sphere valve plate 10 being arranged in described lower valve body 3; The left end of described notch shape sphere valve plate 10 is disposed with hard valve component 5, spring assembly 51 and pressure valve assembly 4, and the torsion while making valve opening is like this less, and reset speed is fast, can residual foreign material.The lower end of described notch shape sphere valve plate 10 is connected with the flange 12 that is arranged on lower valve body 3 bottoms by lower valve rod 11; Make the fixing seal better effects if of valve plate and valve body.
Wherein, be evenly provided with filler 9 and filler dividing plate 8 in the activity space between described upper valve rod 2 and described upper valve body 1, the upper-end surface of described upper valve body 1 is disposed with Gland 7 and hold-down grid 6.
The valve plate setting of ball valve of the present utility model is the structure of notch shape, and it also has shear action to seal ring in the time damming, therefore its better tightness, and control accuracy is higher.Therefore be relatively applicable to regulate greatly the system of ratio, and to obviously excellent and other modulating valve of the control of cellulosic, slip class fluid.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (2)
1. metal hard seal V-type otch ball valve, it is characterized in that, comprise the upper valve body (1) of longitudinal layout and the lower valve body (3) of lateral arrangement, in described upper valve body (1), be provided with upper valve rod (2), the lower end of described upper valve rod (2) is connected with the notch shape sphere valve plate (10) being arranged in described lower valve body (3); The left end of described notch shape sphere valve plate (10) is disposed with hard valve component and pressure valve assembly (4), and the lower end of described notch shape sphere valve plate (10) is connected with the flange (12) that is arranged on lower valve body (3) bottom by lower valve rod (11).
2. metal hard seal V-type otch ball valve as claimed in claim 1, it is characterized in that, in activity space between described upper valve rod (2) and described upper valve body (1), be evenly provided with filler (9) and filler dividing plate (8), the upper-end surface of described upper valve body (1) is disposed with Gland (7) and hold-down grid (6).
