Why does the pressure cooker come out of that small hole in the top of the handle?

Why pressure cookers.

Blowing air out of that little hole in the top of the handle? Because the pressure in the pressure cooker is too large, the small hole is the valve of the pressure cookerBecause the pressure in the pressure cooker is too large, the small hole is the outlet valve of the pressure cooker, so it can only be vented from the small hole.

The small hole above the handle of the pressure cooker is the safety self-locking valve, <>

The pressure cooker comes out of the small hole on the handle, which is to prevent the air pressure inside from being too high, and when the air pressure inside reaches a certain level, it will be eliminated from this small hole.

Because the pressure is too high, there will be a small hole to breathe, which can ensure that the food can be well matured under stewing, and also ensure the safety of the pressure cooker.

The pressure cooker mainly shortens the ripening time of food through the pressure in the pot, so it is better sealed and can only be deflated through the small holes on it.

Because this is designed for ease of manufacturing, it can save money.

Because the main principle of the pressure cooker is not to let the heat in the pot come out, and then simmer the food inside, so that the taste is in the pot, so the design of this air outlet will be very small.

The reason why the pressure is over, there is a small junior worker from the top of the handle, that is for the blood pressure function, he is this thing, it is to ensure his pressure, so this thing is very important.

If the pressure cooker is ventilated through the small hole in the handle, it is because the small thick hole over there is probably a small hole there!

If the handle is steamed, it means that the lid is not completely closed--- turn off the heat, and wait for the steam to run out and cover again.

There are three main reasons why the handle of the pressure cooker does not emit air in the middle:

1. One is that the sealing gasket of the pressure cooker's non-opening valve is aging or falling off. Solution: Replace the gasket of the pressure cooker check valve with a new one.

2. Another situation is that the safety lock return device of the pressure cooker handle is faulty, resulting in the failure of the check valve to rise and seal.

3. The last one is that the pressure cooker handle is loose and the return device is displaced.

1. The main air outlet hole on the top may be blocked, check if there are any small items such as rice grains and mung beans that can be stuffed into it, and use a toothpick to get it out, otherwise it will be more dangerous.

2. It is also very likely that it is a problem with the sealing ring or a stainless steel pressure cooker, and the stop lever of the small hole at the front end of the pressure cooker handle is a barometer, which will be deflated when it rises to more than two dows.

3. There is a small piston in the small hole above the handle, which is an insurance mechanism, and it has two functions: after it starts to heat, the air inside is heated and expanded, the water begins to evaporate and vaporize, the pressure gradually increases, and the mixed gas is discharged from the small hole, so that it becomes pure water vapor; When the air is exhausted, it is pure water vapor, and after the air pressure rises to the specified value, the pressure pushes the small piston up to block the small hole and no longer leak. This small piston is also a protective bolt, and the lock handle cannot be rotated to open the cover, so as not to be injured by the wrong opening.

Only when the pressure drops to a safe value after the ceasefire and the safety bolt is dropped can the lid be opened safely.

1. If the sealing ring inside falls off, replace the sealing ring immediately, so that the handle will not leak. 2. If the sealing ring falls dirty, it will also cause air leakage on the handle, so it is necessary to clean and seal it frequently. 3. When the lid of the pressure cooker is damaged, the handle will also leak, just replace the lid.

4. Cover the pot well when using, otherwise the handle will also leak.

There is a small piece of the hole at that position, and the handle is closed and retreats, and then the small pile in the hole can get up and seal the hole, right, the current problem is that the gap between the small pieces of the tube is too large to return to the position, just dial it with chopsticks. Most of the pressure cookers in the hotel kitchen have this problem, and we all settle it ourselves: fill half a bottle of water in a flask, plug the mouth of the bottle tightly with a stopper with a glass tube and thermometer, and use a rubber tube to connect the glass tube to the syringe (or connect a small gas cylinder).

Heat the flask with an alcohol lamp, and you can see from the thermometer that the water in the flask boils as the temperature approaches 100. At this point, you push the syringe piston (or compressor cylinder piston) hard to increase the pressure in the bottle, and you will see that although it is still heating and the temperature of the water is slightly increased, the boiling stops. This indicates that the boiling point of water increases as the pressure increases.

The "pressure cooker" is made according to this principle. The world's first pressure cooker was invented in 1681 by Denis Papin, a French physician, physicist and mechanic. This pressure cooker is very sturdy, the lid is made of iron, the portion is heavy, and it is tightly covered on the pot.

The perimeter of the pot is covered with a metal mesh to prevent accidents**. The pot itself has two layers, **There is an inner pot, and the food to be cooked is placed in the inner pot. After heating, the steam cannot escape, the air pressure in the pot rises, the boiling point of the water also rises, and the food cooks quickly.

During his visit to England, Papin used his pressure cooker for a performance. According to the records of those present, even the hard bones in Papin's pressure cooker became as soft as cheese. Today, many families in our country use "pressure cookers", which cook quickly and save time.

Especially living at high altitudes, it is necessary to use a "pressure cooker" to cook rice. Because the higher the altitude, the lower the air pressure and the lower the boiling point of water. It has been determined that at an altitude of 6,000 meters, the boiling point of water is only about 80.

If there is an air leak in the pressure cooker at home, it may be that the gasket on that lid is broken. You can check it first and then see how to fix it.

Although it is confirmed that the demand curve arises naturally from the theory of consumer choice, the derivation of the demand curve itself is not a theory that proposes consumer behavior. Simply determining how people react to change doesn't require a rigorous analytical framework. However, consumer choice theory is extremely useful.

As we will illustrate in the next section, we can use this theory to more deeply determine the factors that determine family behavior.

Instant Answer Draw budget constraint lines and indifference curves for Pepsi and pizza. Illustrate what happens to the budget constraint line and consumer optimum when pizza** rises. Use your graph to divide this change into income effects and substitution effects.

Four applications. Now that we've established the basic theory of consumer choice, we can now use it to illustrate four questions about how the economy works. However, since each problem involves family decision-making, we can address these issues with the consumer behavior model we just proposed.

Are all demand curves sloping to the bottom right?

In general, when an item** goes up, people buy less. Chapter 4 refers to this normal behavior as the law of demand. This pattern manifests itself in the demand curve sloping to the lower right.

However, as far as economic theory is concerned, the demand curve also sometimes slopes to the upper right. In other words, consumers sometimes defy the law of demand and buy more when one item rises. To illustrate how this can happen, look at Figure 21-12.

In this example, the consumer buys two items – meat and potatoes. Initially, the consumer budget constraint line was a straight line from A to B. The best advantage is c.

When the potato ** rises, the budget constraint line moves inward and is now a straight line from A to D. Now the best thing is e. It is important to note that the rise in potatoes has led consumers to buy more potatoes.

Because of the exhaust problem of the pressure cooker, you only need to press the exhaust hole.

Before each capping, carefully check that the vent of the cap** is unblocked. If you can't see the light in front of the light and the air is not smooth, it must be blocked. You have to clear the blockage before you can cover it.

After capping, the more scientific method is not to add the pressure limiting valve first. After the cold air in the pot is heated and discharged, the center hole is used as the standard to make the air evenly heated, and then the pressure valve is installed in time.

Precautionary measures. 1. Regular inspection: check the pressure limiting valve and float valve, check whether the pressure cooker can be fastened in place, and whether the gasket on the lid is yellow. As soon as a blockage is found, wash it immediately.

If your mouth is not tight, do not use it for a while. The face will leak, take it for repair or no longer use, and the yellow gasket will need to be replaced.

2. Remember not to pack too much food, and leave a proper gap between the food and the side of the pot. Before closing the lid of the pot, make sure that the gas limiting valve is not blocked, and tighten the pressure cooker before **.

3. After the rice is cooked: do not rush to open the pressure cooker, wait for the high-pressure gas to be completely released, that is, wait for the pressure cooker to cool down before removing the pressure limiting valve and opening the lid.

Answer: There is an air valve that can move up and down in the small eye on the handle of the pressure cooker, after heating the pot, the air inside is heated and expanded, the pressure gradually increases, and the hot air is discharged from the small hole, so that the hot gas temperature in the pot is increased to more than 100 degrees. When the hot gas pressure rises to a certain level again, the air valve will be pushed up by the air pressure and block the small eye. Thus continuing to pressurize the food in the pot to be thoroughly cooked or stewed.

If this small hole keeps leaking, the pressure will not rise. Reasons for the constant air leakage:1

The sealing of the valve gasket is not flat, and it may be that the food that was originally stuck on it has not been washed, resulting in air leakage. 2.The gasket of the valve is deformed, resulting in air leakage due to poor sealing.

3.Inaccurate alignment (misalignment of the air valve and the small eye).

Reasons for air leakage through the small holes on the handle: 1. The handle is loose, causing the lid handle to not return to its position, blocking the check valve, resulting in air leakage! If the lever under the handle is not deformed.

You can try it with a screwdriver! You can close the pot and look at the small hole in the handle, whether there is a small piece in it that blocks the valve! If the deformation causes the valve body to bounce up, you need to replace the handle!

The gasket was not pressed properly when it was covered.

Is there a small hole bubbling up?

Can you elaborate on that a little bit more?

Hello, it is probably the following reasons caused by the steam at the handle of the pressure cooker, 1. The handle is loose and the handle of the lid is not returned to block the stop opening valve, resulting in air leakage! If the lever under the handle is not deformed. You can try it with a screwdriver!

You can close the pot and take a good look at the small hole in the front of the handle, whether there is a small piece in it that blocks the valve! If the vertical deformation causes the valve body to be blocked, the socks can not bounce up, and the handle needs to be replaced! 2. The check valve needs to be replaced due to air leakage caused by the aging of the check opening valve.

I hope it helps you and thank you for your trust.

When the pressure in the pot rises to a certain value, the pressure will push the small piston up to block the small hole, and no longer ventilate, if it has been heated for a period of time, it is recommended to suspend the inspection, it may be that there is a problem with the sealing ring of the pressure cooker ear height and width, or there may be food blockage.

The small piston in the small hole in the handle can lock the handle and cannot be rotated to open the cover, so as not to hurt people, if it is still out of gas after heating for a long time, be sure to turn off the fire in time to avoid accidents.

When using a pressure cooker, you should pay attention to safety, and it is best not to cook more than 2 3Especially for liquid food, don't stay in the kitchen all the time.

After the food is cooked, if the small piston at the handle has not gone down, the lid cannot be opened, and it can only be opened after it has fallen, and you can use a wet towel to cover the lid on the pot to cool down.
