Fluid And Target Compound Transmission Protective Device

A protective device for preventing tampering with a pipe system in a building, the pipe system for transmission of a flow of a fluid from an upstream end of the pipe system to a downstream end of the pipe system, the protective device comprising:

• a pipe insert disposed within the pipe system between the upstream and downstream ends;
• a valve within the pipe insert, the valve moveable between open and closed positions, wherein the open position opens the pipe insert, enabling transmission of the flow of the fluid through the pipe insert, and the closed position occludes the pipe insert, disabling transmission of the flow of the fluid through the pipe insert;
• means for preventing transmission of a resonant frequency through the pipe system from the upstream end to the downstream end, said means disposed in-line with the pipe insert;
• and
• a sensor within the pipe insert for disposition within the flow of the fluid to detect one of a target compound and a pressure level in the pipe insert;
• wherein the valve moves from the open position to the closed position when the sensor detects the one of the target compound and the pressure level.

• a pipe insert disposed within the pipe system between the upstream and downstream ends;
• a valve within the pipe insert, the valve moveable between first and second positions, wherein the first position enables transmission of the flow of the fluid through the pipe insert, and the second position disables transmission of the flow of the fluid through the pipe insert;
• guards disposed within the pipe insert, wherein the guards are rigid and define an obstacle to the transmission of the flow in a straight line between the upstream and downstream ends;
• a trap joined in fluid communication with the pipe insert proximate an upstream one of the guards, the trap configured to collect and retain debris introduced into the flow of fluid from upstream of the pipe insert;
• and
• a sensor for disposition within the flow of the fluid to detect one of a target compound in the pipe insert and a pressure level in the pipe system;
• wherein the valve moves from the first position to the second position when the sensor detects the one of the target compound and the pressure level.
