Abstract
PURPOSE: To ensure a quick and accurate detection for the broken position by installing the pressure supply source same as the flow quantity detecting means across the thermoplastic pipe and then obtaining the flow quantity ratio at the heat breakage time of the pipe.
CONSTITUTION: Thermoplastic pipe 1 has the heat breakage at the position of the X marking, and flow quantity Q1 and Q2 of flowmeters 2 and 3 of the breakage time feature as Q1=C×(PC-PO)/l, Q2=C×(PC-PO)/(2L-l) and Q1/ Q2=(2L-l)/l respectively, where L is the wiring length of pipe 1, l is the distance up to the breakage point, PC is the pressure of pressure supply source 4 and PO is the inner pressure at the breakage point each. Accordingly, distance l is shown as l=2L/[(Q1/Q2)+1]. And length L is a known constant, and thus distance which shows the broken area can be obtained immediately and accurately if the ratio is known between Q1 and Q2.
