Abstract
The utility model relates to a discharging valve with dual gate plates, comprising a valve body (1), inlet/outlet valve covers (2), valve plates (4), sealing rings (5), an air cylinder (10), a valve rod (11-1), a flat pad (12), the sealing ring (13), a nut bolt (14) and a gate plate ferrule (15). The run-through inlet valve cover and the run-through outlet valve cover are arranged on the valve body (1), the valve plates (4) are respectively arranged on the inlet valve cover and the outlet valve cover, the upper ends of the two valve plates (4) are connected with the valve rod, and the valve rod (11-1) is connected with the air cylinder (10) which pulls the gate plates; the alloy sealing rings (5) are inlayed at the inlet valve cover and the outlet valve cover, and alloy rings are inlayed at the outer rings of the valve plates (4).
Description
Technical field
The utility model relates to the discharge valve of a kind of powder and fluid, especially the double-flashboard discharge valve.
Background technique
The flashboard discharge valve is the fluid discharge valve of using always.As CN2586023 wedging type double disc parallel seat valve, comprise valve body, valve rod, the import valve seat, the outlet valve seat, with the outlet valve base chamber two longitudinal sections being arranged at the import valve seat is the flashboard of right-angled trapezium, the inclined-plane of two shoe brake plates is relative, the right angle face is relative with the outlet valve seat with the import valve seat respectively, the upper end of wherein being inverted flashboard connects valve rod, pin is respectively arranged on the inclined-plane of two flashboards, the slotted eye that corresponding pin is respectively arranged on two flashboard inclined-planes, at two flashboards, two avris flipper guide is arranged, there are rest pin on a semielliptic spring and the flipper guide and two rest pins on the opposite side guide plate to be connected, slotted eye corresponding to pin is respectively arranged on the two flashboard inclined-planes, a centering block is arranged between the inclined-plane of two shoe brake plates, and the centering block bottom surface is the plane, and another side is that angle is the conical surface of 15 degree.But opening and closing of powder valve is more frequent, and be big to the wearing and tearing of valve plate, and the replacing that often needs repairing causes the equipment stall.As adopt the member costs such as flashboard of full alloy too high again.
Summary of the invention
The utility model purpose is: propose the double-flashboard discharge valve that a kind of sealing and rubbing surface adopt the alloy material, this position is under the prerequisite that guarantees wear-resisting property, significantly improved indexs such as intensity and impact resistance, its mechanical property and life-span are better than conventional wear-resistant ceramic product greatly.
The technical solution of the utility model is: the double-flashboard discharge valve, comprise that valve body, import and outlet valve gap, spring seat, valve plate, seal ring, coupling head, spring, seal ring, gland, cylinder, indirect cover, valve rod, plain cushion, seal ring, nut bolt, flashboard lasso, valve body are provided with the suction valve cover of perforation, outlet valve gap, cover at suction valve cover and outlet valve and to be equipped with two valve plates, the upper end of two valve plates connects valve rod, and valve rod connects the cylinder of pulling flashboard; It is characterized in that suction valve cover, outlet valve gap inlay the alloy seal ring, and alloy circle (tungsten alloy circle), i.e. flashboard lasso are inlayed in the outer ring of valve plate.
The utility model beneficial effect is: the assembly structure that has adopted tensioner to inlay, the soundness and the serviceability of sealed member have been guaranteed, have higher assembly precision, compare, stopped because of high-temperature work environment and the caducous phenomenon of fatigue limit lower seal with the adhesion process of wear-resistant ceramic product; The compatible height of fluid medium is applicable to all kinds of powder and granule shape materials.
