Introduction of flameout protector

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.

Travelling

The little friends and big friends all stand in a line go to travell. Hahaha~~

April 21th, our class went to the Panyu Chimelong Paradise. When we went there forget many things. Map？No！Compass？No！Mobile Phone? No! Didnt check the weather ne

ws. So that day rainy when we have a good time. But we still play the games.

April-16

On April 16 evening, the earth theater strength invites "Extremely To love" - - Alex Fang, Stephy, Miki, Hu Qinglan and directs Ye Nianchen to arrive the Shunde day to bless the city, is "Chinesepercentage hundred" the active relay signature, and for soon screens on 19th in Guangzhou each big theater and Hong Kong synchronization "Extremely Likes" propagandizing drums up support.

That very evening seven o'clock, the day blesses the city really ice-skating rink side the stage already to encircle watertightly, multitudinous young FANS is lifting up high "Alex Fang", "Stephy" and the playbill picture poster raises the head waits for the idol arrival, two buildings all around on the parapet all encircled have filled the person, when this place strength Shanghai, Deng Lixin and the party arrived at the scene, the sharp cry rises from all directions, in the crowd caused an intense tumult.

Excuses

I haven’t posted for a while.
One of the reasons is that I ordered a new pc for my parents last week and then went to Southampotn to set it up for them. I took with me my router to use as a network hub and transfer their personal stuff from the old PC to the new.When I came back I neglected to pick up the power supply for said router, thus rendering myself internetless. Thankfully my mum posted it back and so today I am back online again.
The other reason is that I’m just rubbish and just don’t have anything interesting to say.
Oh yes, and remember that nice moon/venus pairing I told you about last time?
I forgot it was happening and missed it.

My blog

We need to make some decisions about how this blog, or other blogs, might be useful to us, either within smaller groups working on special projects, or in other ways to foster connection and innovation within the teacher. Here are a few bloggy issues to consider:

My blog: the main purpose is introduce something interest of my live. The beatifull pictures.

Right now,The blog is set up only one month. Have a few people to click into my blog. Maybe my experience is very lack. Didn't attract many people to read .

My intention is just to post some random stuff here that I hope is interesting, and give the rest of you a chance to read, comment if you like, and think about this. I know that people in group vary greatly in their experience of blogging, so it's probably good to have some time to experiment with this before we discuss what we really want to do with any of this.

This blog took me about ten minutes to set up and configure, by the way-- this is really fast, easy stuff to do so we can make any kinds of changes, and have any type or combination of blogs very quickly. I just wanted to get this up quickly, so the posts are just samples of the kind of thing I think we should be sharing somewhere, and the links are just sort of placeholders.

There are many different popular blogging software programs, but at NOBLE we just use Blogger.com for everything. The blogs themselves are on our server, but all the creation, configuration, posting, etc., is done at the Blogger.com site. It does everything we need it to do, and it's easy to use.

It was great meeting with all of you today, and I hope you're feeling as hopeful as I am about moving forward together!

"suggestions for lecture presentation"

Blog is more and more popular in all over the world. How to make the lecture presentation became funny. I think the teacher talk about the functions of the blog.Tell us how to make the different from other. How to make the people noticed my blog.I am very interesting in how to earn money from the blog , if you teach me. I will very thanks!!

Introduction

Hello, everybody. I'm Kitty Cat. And I am study in the Shunde Polytechnic Economic Management Deparment. My major is e-commerce. My major make me like to buy things in the website.I 'm good at computer. Like Photoshop/Dreamweaver/Flash......
Sometimes I like to playing games.Because we have many homework to do make me feel borning. So I must play games to relax myself. Sometimes I like to shopping with friends. If you like to jion us. Add me quickly. I'll be very happy.
