Abstract:
A dual lock flow gate includes a valve with a flapper which may be fixed and/or locked in various positions.

Claim (Index 12):
A method of blocking a flow through an oil production string during installation of the string in a casing and unblocking the flow when ready to produce flow through the string comprising the steps of:\n providing a dual lock flow gate (DLFG) above a pump and production tubing above the DLFG; during string installation, blocking a flow through the string by providing a DLFG flapper and a shear pin that interferes with flapper motion such that flapper rotation away from a body through hole is inhibited; after string installation and before production, unblocking a flow through the string by failing the shear pin and enabling flapper rotation away from the body through hole; and, when the flapper has rotated away from the body through hole, substantially preventing flapper rotation by inserting a plunger in the flapper; wherein the plunger is urged to extend from a DLFG body sidewall bore by a spring.
