Abstract

A new generation close valve, one end of the valve screw is installed within a flexible film, the valve is characterized in that the flexible film is set in the annular grooves, the height of the protruding mouth edge of the flexible film is 5 per cent to 25 per cent of the thickness of the flexibility film, the outer surface of the valve is without one-way flow of fluid arrow logo.

Description

A new generation's stop valve

Technical field

The utility model relates to a kind of valving of controlling plumbing fixtures inner fluid.

Background technique

At present, known stop valve structure is when rotating operating handle, when the screw rod at valve body center is rotated along the screw axis direction, inner mobile to valve casing, in the screw rod end of valve inner ring elasticity wafer is housed, ring elasticity wafer is pressed on the aperture that the valve casing inner fluid passes through by screw rod, stops flowing of fluid.Fluid can only one-way flow, if oppositely, fluid can be rolled film edge and cause that film can not block the aperture that the valve casing inner fluid passes through, and closes continuous fluid.

Summary of the invention

Easily boosted in order to overcome existing stop valve ring elasticity wafer by fluid, shortcoming that can only one-way flow, the utility model provides a kind of stop valve of new generation, and this stop valve has overcome the one-way flow restriction of traditional stop valve.

The technological scheme that its technical problem that solves the utility model adopts is: an end end is provided with elastic film in the valve of valve screw rod, elastic film is arranged in the annular groove, the height of elastic film peripheral edge projecting groove mouth is 5% to 25% of this place's elastic film thickness, and the valve outer surface does not have one-directional fluid flow sign arrow.The annular groove that holds elastic film is surrounded by the screw rod end in hard sheet of the ring-type that compresses elastic film and the valve body, the hard sheet of ring-type that compresses elastic film stops fluid to promote elastic film with annular groove, regardless of fluid flow direction, fluid all can not be released elastic film outside the annular groove, so the valve outer surface need not one-directional fluid flow sign arrow.Change the peripheral edge of ring elasticity wafer into annulus that the cross section is an O shape, good sealing effect also can prevent excessive compression damage film.

The beneficial effects of the utility model are that this stop valve has been cancelled the one-way flow restriction of traditional stop valve, the convenient installation.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing is an embodiment's of stop valve a longitudinal section tectonic maps.

1. handle locking screws among the figure, 2. handle, 3. screw rod, 4. screw bolt seat, 5. screw rod seal ring, 6. screw bolt seat seal ring, 7. valve casing mold insert, 8. valve casing main body, 9. hot melting connector A, 10. elastic film, the hard sheet of 11. ring-types, 12. elastic film locking nuts, 13. hot melting connector B.

Embodiment

In the accompanying drawings, the hard sheet of ring-type (11) surrounds an annular groove with the interior end end face of the valve body of screw rod (3), and elastic film (10) is arranged in the annular groove, and the peripheral edge projecting groove of elastic film (10) is outer highly to be 5 to 25% of this place's elastic film thickness.Move when screw rod (3) is rotated in valve, when elastic film (10) turn-offed the fluid passage, regardless of fluid flow direction, fluid all can not be released elastic film (10) outside the annular groove, so this stop valve need not the fluid flow direction restriction.

Claims (1)

  1. A kind of stop valve of new generation, an end end is provided with elastic film in the valve of valve screw rod, it is characterized in that: elastic film is arranged in the annular groove, the height of elastic film peripheral edge projecting groove mouth is 5% to 25% of this place's elastic film thickness, and the valve outer surface does not have one-directional fluid flow sign arrow.
