what are valves types and there symbols?

Gate valve, butterfly valve, ball valve, non- return valve, pressure reducing valve, there are many type however we can classify them into two categories, STOP VALVES & CHECK VALVES.\nDrawing symbols here is not possible, just do a web-search\nGo here to find some details:-\nhttp://en.wikipedia.org/wiki/Valves

is this a quiz? depends on what kind of car you are talking about. most imports only warning light is the float in the master. most domestics have a switch in the proportioning valve. what bleeder valve are you talking about?

Gunmetal is a bronze (copper, tin, etc.) and can be used too make bronze globe valve bodies (see link).  The second link shows a gunmetal globe valve except it has a stainless steel disk and seat.  I have seen globe valves with bronze disks (plugs) so they likely do exist in gunmetal.  Good luck.

the quickest way to figure it out i think would be to call a fitting/valve supply house and ask them. the BSI standard you reference deals with manufacturing. i have found some ISO sets that govern this and some API but im not in India and have yet to build anything in that country so i doubt these will help. unless India uses American Petroleum Industry standards.

I have a drawing that shows the various types of shell and tube exchangers. I believe their functions are self evident if you see the cross sectins.\n\nSend me you email address and I'll send the drawing.

In simplest terms, the valves move like this:\n\n1.  Piston down - intake open, exhaust closed (injecting fuel)\n2.  Piston up - intake closed, exhaust closed (compressing fuel)\n3.  Piston down - intake closed, exhaust closed (igniting fuel)\n4.  Piston up - intake clsoed, exhaust open (expelling gas)\n\n(The exhaust valve opens earlier than in step 4, but it's easier to write it this way.)\n\nSo for the power stage of the 4-stroke cycle (the ignition of the fuel), the valves are closed.  Answer D.

the valves\n\nthe aorta valve prevents the blood from coming back from the aorta to the left ventricle.\n\nthe pulmonary valve prevent the blood from flowing back from the pulmonary artery to the right ventricle.\n\nthe mitril valve prevents blood from flowing from the left ventricle back into the left atrium\n\nthe tricuspid valve prevents blood from flowing from the right ventricle back into the right atrium.

If you are looking for properties of some specific chemical then search for MSDS (Material Safety Dada Sheet) for that particular chemical in Google or Yahoo search engines.\nHere, I am giving you a list of websites which can give you general information on symbols. There will be slight variation in the depth of descriptive material depending on site to site.\nYou can copy and paste following links in your browser's address line:\n(1) www.geocities.com/david_charles_curran/safety\n(2) http://en.wikipedia.org/wiki/Hazard_symbol\n(3) http://www.hse.gov.uk/chip/phrases.htm\n(4) http://www.chem.utoronto.ca/healthsafety/guide/symbols.htm

Braces.\n\nBrackets are [ ] and parens (parenthesis) are ( ).\n\nThey are sometimes refered to as "Curly Brackets" or "curly braces".

The pressure rating versus temperature for these classes of flange ratings is independent of the material being contained.\n\nThe best way to get a table or chart of the relationship between pressure and temperature is to contact a pipe, valve and fitting supplier in your yellow pages. If you can't find one, try the online yellow pages for Houston, Tulsa, Oklahoma City, Dallas or New Orleans.\n\nThe actual ratings are part of copyrighted documents published by ANSI and usually aren't available for free.

These are components (for example) of steam power plants (stationary and marine).  Engineering Handbooks (Marks' Mechanial Engineers' Handbook, etc.) should provide definitions and perhaps examples of steam, air and water pressure reducers and steam desuperheaters.  Visit any large library and ask at the Reference Desk for technical handbooks (or any other books re' steam power plants).\n\nEngineers would contact manufacturers for detailed product information before specifying equipment.\n\nGood luck.

A radio valve is a tube, which is what was used before there were transitors.\n\nMy feeling is that all these devices are nonlinear devices, so V=IR does not hold over a very wide range of parameters. So depending on what you choose for V and I, NONE of these obey ohm's law. However, they might obey ohm's law over some small range of values of V and I.\n\n------------------\nAddendum:\n\nIs there something I am not understanding here? Ohm's Law is a linear law V=I*R, where R is a constant not depending on the applied voltage. Any material or device not satisfying this relation is called nonohmic. Transistors are nonohmic. Diodes are nonohmic. Vacuum tubes (i.e., valves) are nonohmic. Of course, even for ohmic devices, Ohm's law only holds for a certain range of V and I, since outside this range, one witnesses nonlinear behavior. \n\nIf R depends on voltage, so R=R(V), then the relation continues to hold, but it is no longer linear.  \n\nThe references I have attached include multiple examples of diodes, transistors and tubes being described as nonohmic devices. \n\nONLY over certain  values of V and I will any of these devices approximate an ohmic device. Other than that, the V-I relationship will be nonlinear.
