Q:How do you draw the butterfly valve in the engineering drawing?

There is one of the most stupid way: find a picture of the butterfly valve, insert into the CAD, and then follow the trace, and there is a lot of CAD on the network of butterfly valve, yourself down..

Q:Butterfly valve general use occasions

Butterfly valveAlso known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid. On the pipeline, mainly from cutting and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.

Q:Who can give me a download UG butterfly valve, needle valve, diaphragm valve standard model address, Japanese standard, American Standard.

Support many 3D CAD format, such as the commonly used UG, Pro/E, SolidWorks......As for the butterfly you said, don't post the link up, the standard JIS, American Standard ANSI, German standard DIN are.You use Baidu Search "LinkAble PARTcommunity", after the open registration, CAD format, such as UG, ASAHI and then to find the manufacturer home page, which is the valve, you said the Japanese standard, German standard, American Standard valve basically all.

Q:I have a good set of #142 Pontiac heads with small diameter valves. I want to have the heads enlarged to accept the larger Pontiac valves, and I have the larger exhaust valves out of #13 heads and the larger intakes from 6X8 heads. The valves appear ok and shiny on the stems

Roll the valves by the stems on a perfectly flat table. If there is no wobble, your valves are most likely not bent. Take them to a machine shop and have them checked for imperfections and reground and they'll be good as new.

Q:How to use the fire butterfly valve properly?

Clamp and groove type and signal butterfly valve, the first two have what requirements of installation, the operating handle can rotate to open and close the valve installation, signal wiring, mouth down, to prevent water and caused a short circuit three line grounding and alarm line for leakage protection and monitoring of the valve open or closed, general are in line with the alarm valve or flow indicator matched with water, indicating the spacing of not less than 300mm, no other special requirements

Q:I have a 1993 Oldsmobile Cutlass Supreme and I think I have the case of the blow-by. The engine had high mileage, but was rebuilt b/c it stalled while driving. 3.1L V6 gasoline engine. The fuel filter and the fuel pump are brand new. Now we have the same problem a few months later. It stalls while driving. Its been sitting a while and won't start by itself, so I pulled off the air intake hose off of the air filter to spray starting fluid into it. I noticed oil puddled in the air intake hose, so I looked for the PCV valve on the rocker cover. There is a tube going from the air-intake hose to the rocker cover. I popped out the tube from the rocker cover and there is no PCV valve. Just tube. Is that where the PCV valve is supposed to go? If not, where can I find it on the engine? And could that possibly fix the blow-by and the stalling engine? I'd appreciate any help. Thanks in advance.

pcv valve is on the valve cover closest to the firewall.it is attached to a rubber hose that runs to the intake. right below an electrical plug

Q:Have an iron block, aluminum heads, solid roller lifters, Jessel rocker shafts, what should my valve clearances be cold, and hot??

Your cam dictates the valve lash. What cam is in this engine? Contact the cam company. Most have on-line tec support or a 1-800 customer service department.

Q:Does the pneumatic butterfly valve need electricity?

Yes, for emergency power off, use the 24V power belt with pneumatic butterfly coil to allow pneumatic valve to work
