Description

Bay resistance ff .; The coil is aoQ, the bumps are KB and the specified coils are IR, which are connected to the electronic unit of the EB; differentiating link R „S, two voltage divider, Y., and | Gs K; two diodes D.Dr connected in parallel

stress dividers and meetings about their common point; memory block P, key K, drug logic circuit, MB rejection mechanism,

Enter voltage dividers and yu; Ci are connected to the output of the differentiating link Sj С, the output of the voltage divider is to the recording input of the memory block P, and the output of the divider voltage is

, St to the reset input.

The permissive input of key K is connected to the input of the voltage divider. The output of the mi P block is connected to the K. key input. The input of the logic circuit is connected to the output of the EB electronic unit, and the reset input of the VOC logic circuit is outputted from the key C. LogicfcxeMbi LAN is connected to the pipe dismantling actuatorMB

 The voltage divider parameters are selected as follows. that the amplitude of the voltage pulse at the output of the voltage dividers as it passes through the flaw detector sensor

the beginning and end of the pipe is sufficient to control the memory block P only when passing through the sensor large diameter pipes,

. The device works as follows

In the absence of a pipe in the flaw detector sensor on the inputs of the memory block P, the key K and the logic logic circuit, the signals are equal to O,

When passing through the sensor rocked

Large-diameter pipes with a coarse defect at the output of the electronic block of the EB of the flaw detector, a pulse is generated that arrives at the counting input of the drug logic circuit. At the output of the differentiating link .tof 1, the pulse of the voltage of voltage 1 (Fig. 2a) runs. Divider rf f yy shuntkrorshn year

The gas station divider from AND voltage pulse 1 (Fig. 26) is input to the advance of the memory block P and is stored, in the prohibitory input, the key K appears signal I, the key is closed,

When passing through the sensor of a pipe with a gross defect, amplitude 2 {FIG. 26), removed from Dalite.gsch. k ;, is insufficient to reset the memory block, key K is closed and pulse 2 (Fig. 2a) does not pass from the output of the differentiating link through key K to the logic circuit of the LAN. The electronic unit of the electronic unit of the firescope generates a pulse of capital, which is supplied to the counting input of the logic circuit.

When a tube end passes through the flaw detector sensor, an impulse is formed at the output of the EB unit of the flaw detector and is fed to the counting input of the LS logic circuit.

At the output of a differentiator link, a pulse 3 is formed {fig. 2a), the voltage divider Rg, Rz is bridged by diode D, Pulse amplitude 3 (Fig, 26) at the output of divider Ig, Ki,: sufficient to reset memory block P, the voltage from the inhibitory input of key K is removed and pulse 3 (Fig , 2a) passes through the key K to the reset input of the logical logic circuit.

The logic circuit of the LAN is reset. Since the counting input of the drug logic circuit received more than two pulses during the monitoring time of the pipe, a signal including an actuator (iJMi. 1) is generated at the drug output.

When passing through the flaw detector sensor the beginning of the pipe “of small diameter with a coarse defect, the amplitude of the voltage pulse 1 (fng, 2d) removed from the divider

of, c is insufficient to write the memory block P and the key K remains open. An impulse is sent to the counting input of the LS logic circuit (FIG. 1) from the electronic unit EB of the flaw detector

When a pipe section with a gross defect passes through the sensor, the amplitude of impulse 2 (FIG. 2d) is insufficient for passing through the key K and the reset input of the LS logic circuit does not pass. A pulse is sent to the counting input of the local LAN circuit from the EB of the flaw detector.

When passing the sensor through the sensor to the counting input of the LS logic circuit from the electronic unit of the electronic detector of the flaw detector, the needle pulse starts. The amplitude of the pulse 3 (Fig. 2d) is sufficient to pass through the key K, and the logical logic circuit is set to the initial state. Since during the time the pipe was inspected, more than two pulses were received from the electronic unit of the electronic detector of the flaw detector by the counting input of the logic circuit of the device, when the logic circuitry did not reset the LAN to its initial state. a signal is generated that includes runner-1H fviexaHH3M rejection MB.

Thus, during the passage of pipes of different diameters, with a gross defect, a voltage pulse generated by

The rents link at the moment when the pipe section with a gross defect passes through the sensor, the device is not perceived as a pulse of the pipe, and the pipe is rejected.
