Introduction of flameout protector

http://tafe.blogbus.com/files/11775917610.doc
The purpose of flameout protector: When we use the cook top, the fire may be extinct because of the wind or overflowing water. In this case, the protector may cut off gas to prevent some accidents happening because of its leakage, such as poisoning, explosion or fire. In this way, it realizes its safety protection function.

The first step: Piezoelectricity.
The second step: Valve-open condition.
The top of the thermocouple is heated by fire, and it causes thermo electromotive force. Then it will be in series between the closed circuit and the valve. Outside force and the magnetic field breathe the valve and keep it open, and the gas channel is open.
The third step: Cut off gas in sudden flameout condition.
When the fire is extinct because of wind or overflowing water, the thermo electromotive potential will minish quickly, and the ferrite core will come back to its original place to cut off the gas because of the loss of the spring effect.
Attention:
1. Thermocouple
1) There mustn’t be any damage or peeling off for the cover of insulation wire or insulation sleeve, otherwise it will cause short circuit, which will influence the normal operation of the valve.
2) The fix-up of the thermocouple must dissipate heat to reduce the heat accumulation of fixing board and thermocouple copper. This can shorten the valve-closing time when there is sudden flameout.
3) The heated part of a thermocouple must be on the top of 2-3mm. Not to put the top into the fire, otherwise it may reduce the potential and shorten its life.

2. Solenoid valve
1) Prevent the valve from being strongly striken in the process of installation and shipment, otherwise it may influence its normal performance.
2) Before installation, the user must check the valve flatly on the test clamps with some prepressing. It is not allowed to be freely-flip. This assures that magnetic material won’t be damaged by colliding, otherwise it will influence the magnetic force.
3) Clean the impurity such as aluminum or oil left on the inner wall of the stove and the surface of the valve.
4) Keep the good connection of the solenoid valve and thermocouple. Prevent the safety protection device from operating abnormally because of too big contact resistance.
5) The warehouse of solenoid valves must be dry and ventilated and strictly prohibit extrusion.

Electronic Commerce

Over the thousands of years that people have engaged in commerce with one another, they have adopted the tools and technologies that became available. For example, the advent of sailing ships in ancient times opened new avenues of trade to buyers and sellers. More recent innovations, such as the printing press, the steam engine, and the telephone, have each changed the way in which people conducted commerce activities.
For decades, firms have used various electronic communications tools to conduct different kind of business transactions. Banks have used EFTs to move customers’ money around the world, all kinds of businesses have used EDI to place orders and send invoices, and retailers have used television advertising to generate telephone orders from the general public for all kinds of merchandise.

Have a good time in Chimelong paradise

First, let me show you some beautiful pictures!
This is the gate of Chimelong paradise.

There is full of smog when we saw the act! It is very astoundment.

The oil is on the ocean, this scene strike my heart.

Prevent computer eyestrain

Sit at least 20 inches away from the screen, and place it at or slightly below your eye level.
From the 20-20-20 rule: every 20 minutes, focus on something at least 20 feet away for 20 seconds.
Post a reminder near your screen that says “ BLINK”. Research shows we blink far less often when staring at a computer and that is a major contributor to eyestrain.
