Abstract
The single-use valve to be installed on a line for transporting a fluid includes a tubular body, which is intended to be placed on the line and contains a mobile element that is able to take up two positions in the tubular body. Each position allows the fluid to pass through the tubular body or not, one being a standby position, while the other is an active position. Inside the tubular body, a driver able to move the mobile element such that the mobile element passes from its standby position to the active position. The driver includes a pretensioned elastic device. Outside the tubular body, a device for maintaining the pretension connects to a controller able to deactivate the device for maintaining the tension.
Claims10
A single-use valve to be installed on a line for transporting fluid, the valve comprising:
- a tubular body having an inlet end and an outlet end and being aligned with the line so as to flow fluid from said inlet end to said outlet end, said tubular body having a fluid tight seal between said inlet end and said outlet end;
- a movable member arranged within said tubular body, said movable member having a first position and a second position relative to said tubular body, said first position corresponding to said tubular body being in a standby configuration, said standby configuration corresponding to stopped fluid flow through said tubular body and at least one side of the line, said second position corresponding to said tubular body being in an active configuration, said active configuration corresponding to activated fluid flow through said tubular body and both sides of the line;
- a driving means arranged within said tubular body, said movable member being moveable from said first position to said second position according to said driving means, said driving means being comprised of a pre-stressed spring;
- means for maintaining pre-tension positioned external to said tubular body and removably engaged to said movable member through said tubular body in said first position;
- and
- control means connected to said means for maintaining pre-tension, said means for maintaining pre-tension engaging said movable member according to said control means.
