Title:
Pump valve mechanism
Abstract:
A method for cleaning tubes and heat exchangers provides an oscillating pump/valve mechanism to provide a periodic waveform of shocks to fouled tubes. Preferably, a pair of pneumatic control valves operates an actuator to oscillate a valve within a valve block, and isolation of a fluid within a manifold in the block creates a pumping action from the valve, to create an intense fluid shock wave to clean interior surfaces tubes.
