Abstract
Equipment for intercepting and diverting liquid circulation flow includes three chambers and a series of valves. The chambers are equipped with a connection device with arrival or supply lines, communicating with each other, of which only a first chamber communicates with second and third chambers. Communication between the first and second chambers and between the first and third chambers each is obtained by at least two valves, one is a flow-rate valve and at least one is an equalizer valve. An upstream or downstream of each equalizer valve is coupled with a fixed or adjustable flow-blocking device. The second and third chambers do not communicate and include a three-way valve in common with each other, or include two one-way valves in counterposition. One one-way valve is open when the other is closed and vice versa, and the three-way valve or the two one-way valves are coupled with a discharge valve.
