The pressure cooker only shows its advantages if it is used correctly and is durable. The use of the pot should be carried out as follows.
Wipe oil
Unused new pot, the sealing ring is more flexible, please add a small amount of food oil on the top and bottom of the pot according to the arrow shown in the figure to facilitate the first opening and closing. The lid, body and handle should be cleaned before each use to facilitate the closing.
2. Put food
When placing food, the food and water should not exceed four-fifths of the pot capacity, and the water or soup should not be less than 400 ml (about two bowls).
3. Cover
(1) Before closing the cover, check whether the exhaust pipe is unblocked, the anti-blocking cover is clean, the safety valve is intact, the float activity is freely up and down, and it is in the falling position.
(2) Place the lid flat on the pot body to fix the pot body, and rotate the lid in a clockwise direction as shown in the figure until the upper and lower handles are completely coincident. At this time, it is just moved to the working position, and the float valve is completely exposed.
4. Heating
After the cover is closed, it can be heated by the fire. When a small amount of steam is slowly discharged from the exhaust pipe, the pressure limiting valve is buckled to the exhaust pipe, and then the float will rise until the exhaust pipe is “嘶嘶â€. After the gas, the furnace temperature can be appropriately lowered to keep the exhaust gas until cooking is completed.
5. Cooling, deflation
After cooking, it can be naturally cooled at room temperature. If it is to be eaten immediately, it can be depressurized by forced cooling (ie, drenched with water or immersed in water). After cooling, the pressure limiting valve can be lightly put out and the remaining gas can be placed. Drop it.
6. Open the cover
See that the exhaust pipe has no steam discharge, and the float falls, you can open the cover in the counterclockwise direction. If the float does not fall, it proves that there is pressure in the pot. At this time, the pneumatic interlocking device will play an insurance role. It is impossible to open the lid. Do not open the lid. Apply chopsticks to press the indicator valve down so that the remaining gas in the pot is cleared before opening the lid.
Terms and Conditions
(1) Before each use, carefully check whether the venting port of the pressure limiting valve is unobstructed (can be cleared by a toothpick), and keep the anti-blocking cover clean;
(2) Do not pack too much food in the pot, generally should not exceed three-quarters of the height of the pot. For foods that are more easily swelled (such as kelp, mung beans, corn, etc.), should not exceed half of the body;
(3) When closing the cover, the cover mark of the lid and the body should be fully engaged. When you are in place, don't overpower your head too much;
(4) After heating the cover, see the upper limit pressure valve cover when there is more steam discharged from the pressure limiting exhaust hole;
(5) When the pressure limiting valve is working, reduce the small firepower and keep the pressure valve to move slightly;
(6) Before the cover is opened, the pressure must be completely reduced, that is, the valve plug of the protection device is lowered and reset before the cover can be opened. Do not force the handle;
(7) The general pressure cooker specifies a safe service life of not more than eight years.
Grinding head is a kind of small handle grinding tools, used in electric mills, hanging mills, hand electric drills. There are many kinds of diamond grinding head, ceramic grinding head, rubber grinding head, diamond grinding head, emery cloth grinding head.
Ceramic grinding head: grain size sand (generally brown corundum, white corundum, chrome corundum, silicon carbide) sintered by ceramic binder, with a metal handle in the center. Mainly grinding all kinds of metal, for grinding the inner wall of aperture, mold correction. Rubber grinding head: fine sand is synthesized by rubber binder for the polishing of mould
Diamond grinding head: A kind of stone material, ceramic materials and other non-metallic materials of grinding tools, especially involving a with diamond alloy grinding tools for grinding body, it includes substrate and a mill body, in which several mill body clearance to fixed to the substrate, the grinding surface of the grinding head grinding body also set a clearance, among them, the substrate is best by a certain toughness of adhesive materials, The grinding body is preferably made of diamond alloy material. The utility model has the advantages of high grinding performance, simple manufacturing and low cost, high grinding quality and being suitable for large-scale grinding
