Method for manufacturing a petal valve

摘要

A method for the production of a valve is provided comprising molding a valve body with a first mold, preloading the valve body with a second mold, molding a sealing portion in an open position onto the valve body, and releasing the preloaded valve body. The sealing portion enters a closed position when the preloaded valve body is released. When the valve is in use, the sealing portion opens when under a fluid pressure, and closes when the pressure is released.

1. A method for the production of a petal valve comprising:
molding a petal valve in an open position; using a substantially rigid skeleton to reverse at least petals of the petal valve to a closed position; and affixing the substantially rigid skeleton onto the petal valve, wherein the substantially rigid skeleton keeps the petal valve in the closed position, and wherein the open position is inside out relative to the closed position.
