Abstract
The utility model relates to a balloon valve, mainly used for the transmitting control of various solid-like and liquid-like materials in chemical, food, medicine and other industries. The features including valve (2) and the flashboard (3) are: said valve (2), a track (4) is set on whose left and right side walls , the left and right side wall set up, flashboards (3) are inserted in the track (4) on both left and right sides, said valve (2), balloon groove (5), balloon groove (5)embedding balloon, said balloon (6) conjugates with the top surface or/and bottom surface. Balloon charges when flashboards close, the contact between the balloon and the top and bottom surfaces of the flashboards is sealed, balloon discharges and automatically shrinks, then the flashboards can be opened electrically, pneumatically, or manually. The utility model adopt balloon thread seal between valve body and flashboard, thus seal contact surface is small, wearing out is low, and sealing surface will not be seized by powdered materials. Therefore the utility model can not only be used in transmitting control of liquid form materials, but also conveyor control of all kinds of solid, powdery materials. It is applied widely.
Description
Technical field
The utility model relates to a kind of gate valve, especially relates to a kind of air bag gate valve.Be mainly used in the various solid shapes of industries such as chemical industry, food, medicine, the conveying control of liquid-state material.
Background technique
Gate valve structure in the past as shown in Figure 1.Form by valve body and flashboard.Plane sealing is adopted in sealing between its valve body and the flashboard, and surface of contact is big, easily plucking, wearing and tearing and produce the gap.As being used for the control of granular material, powdered granule is easy to enter the sealing surface between valve body and the flashboard and is stuck.Therefore it can only be used for the control of general liquid-state material.And the conveying that is not suitable for solid shape material is controlled.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of liquid-state material that both gone for is provided, and goes for the air bag gate valve of the conveying control of solid, granular material again.
The purpose of this utility model is achieved in that a kind of air bag gate valve, comprises valve body and flashboard, it is characterized in that:
Described valve body, its left and right sidewall is provided with guide rail, and the flashboard and arranged on left and right sides is inserted in this guide rail;
Described valve body, top end in it are set air bag in air bag groove or/and offer the air bag groove on the interior bottom end;
Described air bag cooperates with flashboard top end or/and bottom end.
The utility model air bag gate valve, described air bag geosynclinal convex go out or are arranged with interior top end in valve body or/and on the interior bottom end.
Airbag aeration when flashboard cuts out, air bag and flashboard top end and bottom end contact seal; Air bags, air bag shrinks automatically, can electronic, pneumatic or manual unlocking flashboard.Adopt the air bag linear sealing between valve body of the present utility model and the flashboard, sealing contact surface is little, and it is little to wear and tear, and sealing surface can not sealed stuck by granular material.Therefore not only can be used for the conveying control of liquid-state material, the conveying control of all right various solids, granular material.Therefore applied widely.
