Abstract
The utility model relates to a two-flow sluice valve which belongs to valve class. The utility model uses a valve composed of a valve body, a support frame provided with a screw nut and an oil cup, a leading screw, a hand wheel fixed on the upper end of the leading screw, a valve plate hinged with the lower end of the leading screw and a sealing device which is positioned on the support frame and is composed of a press cover and filling materials as foundation, wherein, a U-shaped concave groove is arranged on the inner wall of the valve body; one lateral face of the groove is straight, and the other lateral face is oblique; one lateral face of the valve plate is straight, and the other lateral face is oblique and forms a wedge shape. The valve has pretightening force and good closing sealing property; the valve plate can be subsided for sequentially using after the valve is abraded; the valve is formed by welding.
Description
The utility model belongs to valve type.
Existing gate valve is by valve body, the support that screw and lubricating cup are housed, leading screw, be fixed on that the seal arrangement be made up of gland and filler between handwheel, the flashboard that is hinged on the leading screw lower end, leading screw and the support of leading screw upper end forms.The problem of this valve is: is that casting forms, is prone to sand holes and pore, influence sealing effect, and heavy, more distinct issues are: the flashboard bi-side are parallel, the pretightening force that does not have, sealing effect is relatively poor.
The purpose of this utility model is: provide a kind of lightweight, flashboard has pretightening force, the two phase flow gate valve of good sealing effect.
Technical measures of the present utility model are: based on the valve of being made up of the seal arrangement of being made up of gland and filler on valve body, the support that screw and lubricating cup are housed, leading screw, the handwheel that is fixed on the leading screw upper end, the flashboard that is hinged on the leading screw lower end, the support, the chase groove that U-shaped is arranged on the inwall of valve body, a side of groove is straight, another side is oblique, a side of flashboard is straight, and another side is the oblique wedge shape that is.
Gate valve of the present utility model because a side of flashboard is oblique, contacts with the prism of valve body U-shaped chase groove; Make flashboard have pretightening force, valve has the good effect of closing good airproof performance.
Accompanying drawing is a structural representation of the present utility model.
7 supports among the figure.The screw of adorning on the support cooperates with leading screw 11, and oily mast 8 is housed on the support, lubricated leading screw 11 and screw.Be fixed with handwheel 9 in leading screw 11 upper ends by locking nut 10, the seal arrangement of being made up of gland 6 and filler to leading screw and support is housed on the support; 4 one sides of flashboard of the present utility model are straight, and another side is the oblique wedge shape that is; The chase groove that U-shaped is arranged on the inwall of valve body, a side of groove is straight, and another side is oblique, and for the convenience of processing, valve body can be for being made up of left valve barrel 1 and right valve barrel 3 and the U-shaped connecting plate 2 of seam between two valves.Gate valve of the present utility model can adopt to be welded to form structure, and lightweight characteristics are so just arranged.Because flashboard 4 is wedge shape, matches with the chase groove of valve interior wall, has pretightening force, closes good airproof performance, can sink to continuing the characteristics of using after the wearing and tearing.
