The gauge-switch of pressure К/В - a design and a functioning principle

Principle of functioning of the gauge-switch of pressure К/В

1 — Shtyrevaja the plug
2 — Contact points
3 — the Directing pin

4 — the Pusher
5 — the Disk spring of a high pressure
6 — the Disk spring of low pressure


The pressure gauge-switch is included in a line of a high pressure of a receiver-dehumidifier and serves for compressor K/V switching-off at excessive increase or pressure drop in a line.

So pressure lowering in высоконапорной more low 177 кПа the gauge-switch perceives lines as a signal of development of leaks of a coolant and stops the compressor in order to avoid irreversible losses of a working body, the high pressure in a line is excessive (from above 2940 кПа) can lead to destruction of components of a refrigerator path and also demands compressor switching-off.
