You're in the kitchen, and the blue flames are on fire, and a pot of water in a few minutes. You think it's normal。
But if you start to get yellow and high, it takes two or three minutes to burn the same pot of water and leave a black ash on the bottom of the pot when it's off -- it's not your stove that's broken, it's the gas that comes into your house。
The term “diether” has been heard for the first time by many people following the incident of shinyangbashi. The company mixed 15. 69% of the dimethyl ethers into liquefied gas and was closed down. The numbers sound professional and translate into three words of change in your kitchen: impatience。
Pure liquefied gas flames are stable in blue, burning water fast, and the bottom is clean. The flame is yellow and loose when it is mixed, there may be a “single” fire when it closes, black ash on the bottom of the pot, and the ducts become softer, sticky and cracky。
What does it mean to crack a tube? A leak. What happens after the leak? You should have an answer。
So the question is not "how to choose a better gas supplier," but how to confirm that the company that's giving gas to your family now doesn't turn this into an accident in your kitchen。
First line of defense. Look at that
The airman came to the door and put the bottle to the corner and left. You paid for it, but you didn't ask: "who's got the gas?"
You have every right to ask. And they have to answer。
The state has a licensing system for the operation of gas, and each legally operated gas enterprise has a gas operating licence issued by the county and above. Without this certificate, he sells himself. A fine of between 50,000 and 500,000 at a time. Guangzhou qingxiang energy company was fined 1,368,000 yuan for operating without a license。
What you can do is simple:
Unlicensed suppliers have a number of visible features: ordinary vans and even private cars giving gas, without dangerous chemicals transport markings; no fixed place of business, with a cell phone number; and cheap prices. The cheap amount of money it saved on security costs — you take care of it。
What do you deserve when you pay
You paid for more than a can of gas to burn. The costs charged by the regular supplier include the safety and security of your home。
The first is security of the distribution chain. The transport vehicle must be a specialized chemical transport vehicle with fire extinguishers; the air transporter must have a gas practitioner's qualification issued by the provincial construction department; each bottle “one-size-a-barrel” is filled only with its own proprietary cylinder and not with expired scrap. The gas cylinder you receive must indicate the name of the unit of supply and the service phone。
The second is regular security checks. At least one security check per year is made free of charge for urban residents and at least two for rural residents. Inspections include piping erosion, loose interfaces, aging ducts, valve sealing, ventilation in the air environment - not just taking an instrument to detect leaks, but sorting out those that you do not normally find。
After the check, i'll give you a written result, and i'll find out what's wrong with the rectification notice, and then i'll follow up on it。
If the supplier you're using, you've never come to the door, or you've changed the bottle, and you're not looking for anything -- the services you deserve have been withheld。
The third is emergency relief. The compliance enterprise has a 24-hour crisis hotline, which reaches the site within 30 minutes of receiving a gas leak report; the in-house failure maintenance service reaches the door within 4 hours and is normally cleared within 4 hours. You can put this number in your phone book when you sign up。
If the other party doesn't have a 24-hour hotline, or the number given is picked up only during working hours -- in case your house leaks at night, who are you calling
If you already smell something wrong
It's not "gas" -- it's stench. Normal liquefied gas smells of snotty eggs. If you smell it fade, or there's a sweet smell that doesn't add up, don't doubt your nose。
The simplest test is to weigh the full bottle (generally 14-15kg for domestic ysp35. 5), minus the empty bottle weight to see if the standard is met. If the weight is fine, but the burning time is significantly shorter than before, it is generally possible to determine that there is a problem with the gas。
What if i find something wrong? Discontinuation, retention of bottles and instruments, and then call 12315 (market supervision) or 12345 (government helpline). Do not take the idea of "will run out of this bottle" - the gas mixed with diaether will continue to corrupt your house's tubes and seals, even if the gas is burned out, the corroded equipment is still in place, and the risk of leakage is buried next time the pure liquid gas is replaced。
A can of gas is safe. You confirmed it
The state has a licensing system, local regulatory platforms and standards of service for enterprises. But eventually it's really safe to turn these systems into your kitchen, and you ask more and look at them every time you breathe。
Next time the airman comes in, you can do four things:
Good business isn't afraid of you. I can't let you ask. You sleep well in your kitchen
