five points for choosing stoves

1 The types of gas stoves should be suitable for local gas sources

it is necessary to know whether the gas used in your home is natural gas, artificial gas or liquefied petroleum gas. The calorific value and gas pressure of these three kinds of gases are different. If the type of stove is inconsistent with the gas, danger may occur, so. Do not mix stoves used for different gas sources. Before choosing stoves, you should first know the type of gas used. When purchasing domestic gas stoves, customers should pay attention to what kind of gas is indicated on the packing box, and can also distinguish the type of gas from the type of domestic gas stoves. For example, for jz-2t-a domestic gas stove, J represents domestic use, Z represents stove, 2 represents two eye stove, and T represents natural gas. If the letter is r, it stands for artificial gas, and Y stands for liquefied petroleum gas

2. Packaging and identification should be complete

this is very important. If it is a "three noes" product, do not buy it easily, otherwise it will cause danger to your personal safety. Generally speaking, the name, address and model of the manufacturer should be marked on the package, and each stove should have a certificate of conformity. In the instruction manual, the side plate of the cooker should have a nameplate (i.e. product trademark), and the nameplate should also indicate the manufacturer name, model, applicable gas and pressure, heat flow and production date

3. Proper heat flow and good air tightness

heat flow: the larger the heat flow value of the domestic gas stove design, the stronger the heating capacity, that is, the more powerful the firepower we usually say. However, in fact, the size of the heat flow should be compatible with the cooking method and the stove. If only a large heat flow is pursued, the thermal efficiency of the stove will be greatly reduced and the emission of waste smoke will be increased

air tightness: if the gas tightness of the stoves purchased and used is unqualified, it is the biggest hidden danger of safety accidents. Here is a simple detection method: connect the air source, turn off the knob, and brush the plastic pipeline, valve body and interface piece with soap liquid. If there is no gas leakage, it means that the air tightness is good, and you can buy it with confidence

4. Body quality and ignition switch

body quality selection: the appearance of the gas stove should be beautiful and generous, and there should be no collision around the body. Press the table by hand. There should be no obvious warpage; Hold the two corners of the cooker by hand and screw it back and forth. The cooker should not be deformed. The panel material of the cooker cannot use tinplate (magnet adsorption can be used to distinguish whether it is tinplate or stainless steel material); The surface of some products made of cast iron, steel plate and other materials shall be painted evenly without blistering or falling off. The overall structure of the gas stove should be stable and reliable. The stove surface should be smooth and flat without obvious warpage. The installation of parts and components should be firm and reliable without looseness. The stove head and fire cover of the stove should be processed carefully without obvious burrs

ignition switch: the position of the ignition switch, i.e. on (0n) and off (off), as well as the position of high and low fire (generally with pattern marks) should be clearly and accurately marked; When igniting with an electronic ignition switch, the sound should be clear and powerful. If the sound of lighting is soft and stuffy, it is likely to be a fake product. Generally, the qualified stove ignition switch has a continuous service life of more than 6000 times, and the air tightness of the cock is still qualified; The number of igniters of inferior products is less than 2000. Generally, if qualified products are ignited for 10 times continuously, the number of times of ignition shall not be less than 8, and all fire holes shall be burned all over within 4 seconds

5. Flame burning state

this is an important embodiment of the combustion quality of the stove. Generally, the outer flame should be light blue when burning. (sometimes it may be orange, which indicates that there are impurities or a small amount of air in the fuel gas, but it does not affect normal use). After ignition, adjust the flame size control button, and the large and small fires should have obvious layers and stable combustion. Even if it is adjusted to the minimum state, or the valve is turned down, it should still be able to burn normally, without jumping, quenching and tempering

generally, the service life of good gas stoves is 5-10 years (according to the relevant national regulations, that is, the standard ignition is not less than 5000 times), while the service life of poor gas stoves is only 1-2 years, and unsafe personal casualties will be caused in the process of use. In addition, due to different gas qualities in various regions, especially artificial gas, there are great differences, so. When purchasing gas stoves, consumers had better choose gas stoves that have been tested and approved by the local geological inspection department and are suitable for the local gas source

how to maintain the cooker

1. Take good care of the stove and keep it clean and intact. The fire hole on the burner is easy to be blocked by dirt such as porridge, vegetable soup, medicine juice, dust, etc., so it should be decontaminated at any time, wipe off water stains, and use fine iron wire to dredge the fire hole, so as to keep the stove clean and the gas unblocked

2. Always check the sealing performance of the plug valve (the valve at the joint of metal pipe and rubber pipe) and oil it in time

3. The connecting hose should be regularly checked for cracks and aging, and the new hose should be replaced in time if problems are found

4. After burning for a long time, the temperature of the stove is high. It is necessary to prevent dripping of cooling water to avoid falling off the paint on the stove surface
