Abstract:
A pyrovalve, comprising:a first tubing section; a second tubing section disposed in spaced-apart relation such that a conveying path between the first and second tubing section is established; an opening disposed between the first and second tubing sections; a valve body fixedly attached to the first and second tubing sections, the valve body having a bore; a ram disposed inside the bore of the valve body; a slug disposed in the opening between the first tubing section and the second tubing section, the slug being held in position by a frictional fit; and, a combustion chamber disposed in operative relation to the ram such that when an explosive material is ignited the pressure inside the chamber causes the ram to move through the bore to strike the slug and to displace it from the opening between the first and second tubing sections such that the valve is opened.
