Abstract
An improved pilot system that allows an automatic maintenance valve to be flushed of buildup. The improved pilot system is used to flush the three chambers of an automatic control valve. The pilot system comprises of lines, ball valves, a strainer, a restrainer plug, a flow stabilizer, a flow restrictor, a pressure reducing pilot, and a couple of isolating valves.
Claims1
An improved pilot system that allows an automatic control valve to be flushed of buildup, the improved pilot system consists of:
- a first t-fitting that connects to an inlet port of an automatic control valve;
- a first ball valve that connects to the first t-fitting;
- a strainer that connects to the first ball valve, the strainer has a restrainer plug, the restrainer plug is used to release buildup into the environment;
- a first line that connects to the strainer;
- a flow restrictor that connects to the first line;
- a flow stabilizer that connects to the flow restrictor;
- a second line that connects the flow stabilizer to a pressure reducing pilot;
- a third line that connects to the pressure reducing pilot;
- a second t-fitting that connects to the third line;
- a second ball valve that connects to the second t-fitting that is used to release buildup into the environment;
- an isolating valve that connects to the second t-fitting and to an outlet valve of the automatic control valve;
- an isolating valve that connects to the flow stabilizer;
- a third t-fitting that connects to the isolating valve and to an upper inlet port of the automatic control valve;
- a third ball valve that connects to the third t-fitting;
- a fourth line that connects the second ball valve to the first t-fitting;
- and a fourth ball valve that connects to an upper outlet port of the automatic control valve.
