Abstract
A valve clack with flow guide cap is formed by valve clack bodies. It features that valve clack is connected to flow guide cap by connection bolt, streamline curve surface design is applied on top surface of flow guide cap for decreasing water flow resistance so as to reduce power losses.
Description
Technical field:
The present invention relates to a kind of valve, particularly relate to the flap of valve.
Background technique:
In the existing flap, valve petal body links to each other with pressing plate by connecting bolt.The end face of pressing plate is generally the plane.Its in the course of the work, exist resistance to water-flow big, thereby cause the big defective of power loss.
Summary of the invention:
Technical problem to be solved by this invention provides and a kind ofly can effectively overcome above-mentioned defective, the flap that has fair water cone that power loss is little.The technical solution adopted for the present invention to solve the technical problems is, a kind of flap that has fair water cone mainly is made up of valve petal body, and its characteristics are: valve petal body is connected with fair water cone by connecting bolt.Owing to adopt such scheme, be not difficult to draw the present invention and have following beneficial effect, the present invention is rational in infrastructure, be skillfully constructed, because the end face of fair water cone adopts the streamline curved design, so it at work, little to resistance to water-flow, thus power loss, tool promotional value reduced.
Description of drawings:
Below in conjunction with drawings and Examples the present invention is described in further detail.
Accompanying drawing is a structural representation of the present invention.
Embodiment:
Referring to accompanying drawing, valve petal body 4 links to each other by connecting bolt 5 with fair water cone 1, is embedded with sealing gasket 3 between valve petal body 4 and the fair water cone 1, and the sealing surface of sealing gasket 3 is the conical surface.Wherein, the middle part of valve petal body 4 is provided with " Y " shape seal ring.Wherein, the end face of fair water cone 1 is the streamline curved surface, reducing resistance to water-flow, thereby reduces power loss.
Claims (2)
1, a kind of flap that has fair water cone mainly is made up of valve petal body, and it is characterized in that: valve petal body is connected with fair water cone by connecting bolt.
2, by the described a kind of flap that has fair water cone of claim 1, it is characterized in that: the end face of fair water cone is the streamline curved surface.
