How does the air release valve of an electric pressure cooker work?

Turn the air vent valve off while cooking. Because in this way things can be cooked, otherwise the effect of an electric pressure cooker will not be achieved. Wait for the pressure cooker to cook before opening the air valve.

Extended information: electric pressure cooker is an upgraded product of traditional pressure cooker and rice cooker, it combines the advantages of pressure cooker and rice cooker, adopts new technologies and new structures such as elastic pressure control, dynamic sealing, external screw cover, displacement adjustable electric switch, etc., fully sealed cooking, continuous adjustable pressure, completely solves the safety problem of pressure cooker, and relieves the potential safety hazards that ordinary pressure cookers have plagued consumers for many years; Its thermal efficiency is greater than 80%, saving time and electricity (more than 30% less electricity than ordinary rice cookers).

An electric pressure cooker is indeed a more practical cooking appliance. It has incomparable advantages over other cooking utensils, can meet a variety of cooking needs, and can achieve a variety of cooking methods quickly, safely and automatically.

This air release valve is closed when in use, so it cannot be allowed to vent. Place the pressure limiting air release valve, dial the pressure limiting air release valve to the "sealed" position, and check that the float valve is down (the float valve is down before heating).

Extended information: When using, first of all, carefully check whether the exhaust hole is unblocked, and whether the hole under the safety valve seat is blocked by residual rice grains or other food debris. If the pot is blocked by food during use, the pot should be moved away from the fire source, the aging rubber ring is easy to make the pressure cooker leak, so it needs to be updated in time.

The handle of the pot lid must be completely overlapped with the handle of the pot before the food can be cooked with electricity, otherwise it will cause the pot to fly off the lid.

When using it, someone added weight to the pressurized valve without authorization in order to increase the pressure in the pot and forcibly shorten the production time. As everyone knows, the pressure in the pot has strict technical parameters, ignoring this scientific design, it is equivalent to joking with your own life, it will cause serious consequences of pot explosion and injury, do not take this risk! In addition.

When using, if the fusible metal sheet (plug) on the pot once it falls off, it is never allowed to be plugged with other metal objects, and the same new part should be replaced.

Closed.

When using a pressure cooker to cook food, the exhaust valve should be closed, because after it is closed, the steam will not come out and can collect in the pot, so that pressure can be generated, so that the food in the pot will become soft and rotten after being pressurized by the steam.

If the exhaust valve is always open, then it means that it has been exhausting, and the gas is discharged, and there is naturally not too much gas in the pot, so the cooked food is not easy to become soft and rotten. Therefore, it is recommended to close the exhaust valve when using the pressure cooker, and then open the exhaust valve to exhaust after cooking.

Precautions for the use of electric pressure cookers.

1. Do not use the electric pressure cooker in flammable materials and humid environments.

2. The height of the food and water added to the inner pot must be specified in accordance with the instructions.

3. The sealing ring cannot be damaged, cannot be replaced by other rubber rings, and the tension ring cannot be used to increase the seal.

4. Do not use hands or other tools to forcibly twist the inner steel ring of the lid, if the steel ring falls off the lid, stop using it and replace the lid.

When the electric pressure cooker is used, the exhaust valve is opened first, and the things to be cooked are put into the pot, and then the valve is closed, and then the electricity is turned on.

Strictly speaking, this is a safety valve, but because it is exhaust when it works, we are used to calling it an exhaust valve, the principle is that when the internal air pressure reaches a certain level, it can be jacked up when we usually rotate the thing when the exhaust hole is opened, at this time it is actually in the pressure relief, the deflating is just gas, so when the pressure cooker is in use, it is closed at first, when the internal air pressure is too large, it will automatically open, and the pressure will automatically close after the pressure drops.

The vent of the electric pressure cooker should be turned off during its normal operation. Only when the pressure in the pot exceeds the predetermined safety pressure, it will automatically jump up and relieve the pressure to ensure the safety of the pressure cooker.

The exhaust valve of the electric pressure cooker is not exhausting when it is working, because the pressure of the electric pressure cooker can be controlled to the state of just not exhausting, so there is no danger of not venting when the electric pressure cooker is working. The electric pressure cooker is easy to block, and if it is blocked by food during use, the power should be turned off.

In general, there will be a clear marking: seal and vent around the exhaust valve of the electric pressure cooker. Under normal use, the exhaust valve of the electric pressure cooker is generally oriented to the left.

In the exhaust state, the exhaust valve is facing to the right. When turning the exhaust valve, pay attention to the fact that the air valve should be a little higher, and the exhaust valve is in working condition. When using an electric pressure cooker to press food, after the lid is tightened, the exhaust valve gear should be set on the sealing gear.

If the gear is set on the exhaust gear, there will be a phenomenon that the pot will be exhausted all the time after it is boiled.
