Under normal use, the pressure cooker will not explode;
First of all, you must be able to use the pressure limiting valve. There are two kinds of pressure limiting valves. One is adjustable and is often used in electric pressure cookers. One is the non-adjustable pressure cooker for ordinary gas. Which is what we often call the exhaust valve. When the pressure in the pressure cooker reaches its designed pressure limit, the pressure limiting valve will exhaust under pressure to ensure that the pressure in the cooker will not exceed the designed range. Then, when in use, the fire is first turned on and pressurized, and then the fire is turned off to maintain the status quo under the condition that the exhaust valve continuously exhausts. But many people don't understand the constant fire, so the pressure in the pot keeps rising. When the exhaust speed of the exhaust nozzle can't reach the safe pressure in the pot, the pressure cooker will explode.
Secondly, the explosion of the pressure cooker is not an easy task, because the design of the pressure cooker is a patent of our country, that is, the frame design. There are long holes around the cover. When the pressure in the pot is too high, and the exhaust valve and the safety valve can't completely release the pressure, the sealing ring will burst open from this long hole, instantly releasing the pressure in the pot and ensuring the safety of users. Therefore, attention should be paid to the aging degree of the sealing ring in use and it should be replaced in time. The cover should not collide and deform to avoid potential safety hazards.
Thirdly, when designing the pressure cooker, there is also a safety function, which is the safety valve. Early safety valves were blown, and now new pots are spring-loaded. When the pressure in the pot exceeds the safety limit, the safety valve will be forced to exhaust by air pressure to protect the safety of users. Therefore, in daily use, we must pay attention to whether the safety valve is blocked or damaged.
Fourth, the small hole in front of the handle, many people do not understand its purpose, it is a floating valve, and some people call it a check valve. Its function is to remind users that the pot is also pressurized, so as to prevent potential safety hazards caused by incorrect opening of the lid after the pot is pressurized.
note:
Another pressure limiting valve is used for electric pressure cookers, which generally has three gears to adjust the pressure in the cooker. For example, the first gear presses some perishable food-ribs, the second gear presses some non-perishable food burdock, and the third gear presses some non-perishable food ribs.
Question 2: What is the function of pressure limiting valve of pressure cooker? The pressure cooker is equipped with a pressure limiting valve (also called an exhaust valve) for the purpose of safety. Its working principle is: when the air pressure in the pot reaches a certain level, it can automatically discharge the air pressure to avoid explosion due to the pressure exceeding the limit.
Question 3: How to use Supor electric pressure cooker, especially how to put food in the pot, put water, close the lid, turn on the power and adjust the time. The pressure limiting valve rotates to the left, cooks to the right, and exhausts after cooking. When the steam is not magnetic, it can be opened.
Question 4: There is a screw on the pressure limiting valve of the pressure cooker, which can be rotated. Do you need to tighten it? You must specify which screw it is.
Is it the hammer with the pot in the middle, or the pressure relief valve next to it? Or a fuse holder.
In a word, these things are usually tight, that is to say, they can't be taken away simply by hand. If they can be moved, but cannot be taken out, they are tight.
If it can be unscrewed easily, it should be tightened.
Question 5: How does the pressure limiting valve of the pressure cooker work? There are two kinds of pressure limiting valves: gravity valve and spring valve.
The principle is that when the air pressure in the pot reaches the gravity (or spring stiffness) of the pressure-limiting valve, the pressure-limiting valve begins to release pressure, so that the pressure in the pot is constant.
In short, junior high school physics knowledge shows that the pressure limiting valve has a certain gravity. When the internal pressure exceeds the limit, F=PS, the thrust exceeds gravity, the pressure limiting valve is jacked up, the gas in the pressure cooker is exhausted, and the pressure is reduced. So is the spring valve.
Question 6: How to set the pressure limiting safety valve of the electric pressure cooker to the sealing position? Turn clockwise to the head.
Question 7: How to use CY * * 50YD6-100+000 pressure limiting valve of Supor electric pressure cooker? This is not easy, you will know after using it. For example, the pressure limiting valve is vented when you use it, which means that it is vented when it is in that position, and then it will seal if you move it slightly to the side with chopsticks. Generally, it is clearly marked on it. If not, there is another difference: the pressure limiting valve in the sealed state is relatively lower than that in the exhaust state.
Question 8: How to use the pressure cooker 1? Please read the instructions before using the pressure cooker. According to the instructions, general food and water should not exceed 3/4 of the pot height; Boiled beans, dried corn, kelp and other easily expandable foods shall not exceed the height of the pot 1/2. And check whether the vent hole of the upper limit pressure valve on the cover is unobstructed, and clean the anti-blocking cover and safety valve (or explosion-proof fusible piece hole).
2. When cooking porridge and bone soup in pressure cooker, the heat should be strictly controlled. Don't use too much firepower. When the pressure limiting valve on the top of the pot is steaming, the heat should be reduced to a suitable time. Don't leave the kitchen too far to do other things, so as not to let the temperature of the pressure cooker get out of control and cause accidents.
From the safety point of view, it is best to use the new pressure cooker with three risks. When cooking bone soup and porridge, turn off the fire properly before boiling to avoid overpressure when the pot boils.
3. Before opening the lid of the pressure cooker, use natural cooling or cold water for forced cooling. First, slowly lift the pressure-limiting valve cover and hear the "hissing" exhaust sound, and then slowly open the lid after all the pressure in the cooker is discharged.
Some people cook porridge, but quickly open the lid before cooling and decompression. The hot porridge flew out with a bang, and it blistered one hand and one face. Although some people use cold water to cool down forcibly, it is also very dangerous to lift the cover without hearing the "hissing" exhaust sound after removing the pressure limiting valve cover. Sometimes, because the vent is blocked and the pressure is not released, blindly opening the lid is easy to cause burns.
4. Pay attention to the safe service life of pressure cooker. According to the manufacturer's regulations, the safe service life of pressure cooker is 8 years, beyond which it can only be used as an ordinary cooker.
5. After the explosion deformation of the pressure cooker, it should not be used as a pressure cooker, but only as an ordinary pot.
In order to save money, some people take the pressure cooker deformed by explosion and put it back to its original state, which is very dangerous. After the explosion and deformation of the pressure cooker, it has destroyed the strength of the pot body and can no longer bear the pressure. Just like a middle-aged and elderly person, his lumbar spine was unfortunately broken. Although it is connected, he can no longer carry 100 kg as he used to.
For your happiness and safety, please use the pressure cooker safely.
Question 9: How to use the pressure limiting valve of the electric pressure cooker to go out and see if the pressure limiting valve is next to the bottom, right next to it; It is wrong to start from a high starting point. You can also try whether to deflate when there is pressure. If the air is deflated, just turn the pressure limiting valve to stop.
