Safety Shut Off, Propane/Butane Bottles.
Discussion
Something I've tried to find out about, maybe someone here knows.
Where is the safety shut off mechanism in (say) a Calor heater? Is it part of the heater or built into the regulator valve?
Yes, I've asked Calor but all I got was a vague answer about it being built in without them actually saying where. I suppose I could flash up the barbecue and push the bottle over to see if it shuts off but thought I'd ask here before doing an emsman.

I think the regulator has a one-way valve on it (kind of like a petrol pump) so if the heat/flames/sparks somehow get 'sucked' back down the tube, it can't get into the main fuel source.
A lot of new equipment would have accelerometers (like what turns your phone screen sideways when you tilt it) that detect when the unit is at 30, 40, 50 degree's and cut off any incoming power source, be that electric in the case of bar heaters, or gas in the case of patio heaters.

All heaters (Calor) have a magnetised safety cut off device, that when the probe is heated by the pilot light, the probe magnetises thereby releasing gas, should the pilot light go out, then the probe demagnetises, the same shutting off the gas supply.Where is the safety shut off mechanism in (say) a Calor heater?

A rubber tube from the heater is fitted with a regulator, the regulator having an “on and off” control knob. With the regulator in one's hand, turning the knob “on and off”, moves, pushes a pin up and down from the regulator, which when the regulator is sat, pushed on to the gas cylinder, the pin on the regulator is mated with another pin in the gas cylinder bottle. So when turning the control knob on the regulator, the regulator pin pushes the pin down the pin in the gas bottle, thereby releasing gas through the regulator, through the rubber tube and to the fire's burner.
Whilst the pin in the gas bottle is spring loaded, it is not uncommon, through dirt ext., for when the regulator is detached from the bottle, for the pin to not completely shut off the gas. So if storing a partially filled bottle over summer etc, to test the bottle for gas leaks, either with a drop of washing up liquid or saliva over the pin head hole.
