It's easy for the water to overflow, and it's not easy to finish everything at once. The kettle is specially filled with water to allow the water to touch the tea leaves and stir them, thereby stimulating the aroma of the tea leaves. This method is more suitable for teas with a relatively strong aroma.

II? Low Punch Swirl

★Tea Type: Black Tea, Loose Leaf White Tea, etc.

This water injection method is suitable for loose black tea and white tea. Or when the next infusions are relatively weak, in order to promote the leaching of the tea soup as quickly as possible, you can use this method.

Shenzhen? Ring water injection

★Tea type: Longjing, Biluochun, Jinjunmei and other relatively delicate tea leaves.

★Water filling method: rotate the edge of the pot when filling water and return to the original point when collecting water.

This method is gentler and requires some soaking time.

Four? Injectionunilateral fixed point water n

★Tea type: broken black tea, etc.

★Water injection method: attach the water injection point to a place on the edge, instead of pouring the tea directly, and let the tea contact and melt slowly . This method is the gentlest.

If you accidentally add too much tea or the tea leaves are broken, you can use a single-sided fixed point. water injection and bring out the soup quickly.

Wu? Inject water at a fixed point in the middle

★Tea type: Qihong, Yinghong and other teas with rich aroma.

★Water injection method: Fixed point water injection is a more extreme method, usually with finer water flow and slow injection. This way only a small part of the tea in the middle is in direct contact with the water, while the other parts are leached at an extremely slow rate, and the layering of tea soup is also the most obvious. This method is more suitable for teas with a fresher taste but richer layers.

What is the principle of the faucet?

The faucet is mainly composed of a spiral valve core, which mainly relies on the rotation of the valve stem. and moving through the thread to achieve the desired flow rate. The effect of opening and closing the water hole. When the valve stem is turned, the threads bite, causing the sealing end of the valve core to move forward and backward;

When the valve core is twisted , the water inlet is sealed and the water outlet position is sealed at the same time, relying on the valve core seal. The end-to-end water outlet is sealed to realize the alternation of cold and hot water.

PrinciPalely through the rotation of the valve stem, the T-thread is moved to realize the opening and closing of the water hole. When we rotate the valve stem, the threads engage. The sealing end of the valve core enters or exits when it enters, it has the function of closing, and when it returns, it has the function of discharging water.

Detailed information:

1. Weight: Don't buy faucets that are too light, mainly because manufacturers hollow out the copper inside to reduce costs. and are not heavy to hold, they are more likely to not withstand bursts of water pressure.

2. Handle: The composite faucet is easy to use because when using the sink, usually only one hand is free.

3. Water outlet: The water outlet placed at a heightmakes it easier to fill the pool.

4. Valve Core: This is the heart of the faucet. Hot and cold faucets use ceramic valve cores. The ones with the best quality are Spanish Circuit, Kangqin in Taiwan and Mingshi in Zhuhai. .

Why does water come It's because the Does the incoming water have pressure? . If the faucet is broken, if it is in the open state when it is broken, it will continue to flow. If it is in the closed state, water will not flow. But when changing the faucet, it is better to turn off the faucet. first level valve before replacing it. In addition, the ball valve It is used in places with a higher degree of tightness and is more expensive. The other type is not called scroll valve. The correct name is a shut-off valve, based on. the princecicipe of low in and high out.
