Q:Timing belt reason for bent valve?
Yes, unless you've left out a critical detail (such as getting water into a cylinder), the timing belt is the most likely explanation for your bent valve. It doesn't neccessarily mean the person who 'did' your timing belt buggered it up, it may have just slipped. The short-ish period between getting work done and the valve getting bent is a little suspicious, but slips happen, especially with belts (as opposed to chains and dual row chains). This puts you in a difficult situation. You may also want to inspect your valvetrain, piston face, and the bore of that cylinder for damage.
Q:What are the functions and uses of butterfly valves?
Butterfly valve (English: butterfly valve) refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. 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:Three eccentric hard sealing butterfly valve, why not fit in the end of the pipe?
The sealing ring will hold up. It does not fit in with the flange end of the pipeline, this addition is the most common and convenient pipeline after purge and easily add pipeline.
Q:What are the uses and classifications of manually operated clip butterfly valves?
In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is 0 degrees -90 degrees between, when rotates to 90 degrees, the valve opens the card completely. Butterfly valves are not only widely used in petroleum, gas, chemical, water treatment and other general industries, but also applied to the cooling water system of thermal power stations.
Q:1989 chevy silverado 2500 need to change valve seals?
If it only puffs blue smoke when you start it and then burns off after a second then its the valve stem seals that need to be replaced which is common on 350 and 305 engine prior to 1990 and have over 150,000 miles or so. The Chilton repair manual explains the procedure on how to replace these.Now if it smokes all the time then it could be caused by worn out rings on your pistons .
Q:Can I reuse intake & exhaust valves?
If the valve is burnt there is no longer something you're able to do with it yet replace it. in the event that they simply desire cleansing up you could lap them in with a lapping compound the threat with this is which you would be able to desire to visual exhibit unit which you don't get close to to the sting of the valve, this is once you will finally end up with a burnt valve. The valve should not be flush with the valve seat this is plenty to close and the warmth of combustion could have an more advantageous effect on the textile.
Q:Butterfly valve, two-way pressure and one-way pressure what is the difference?
One way sealing butterfly valve is the front of the butterfly valve. When it closes, it must face the direction of the medium. The medium flows only in one direction, and the arrow on the valve body indicates the direction of the flow direction of the medium. Attention should be paid to the flow direction of the medium during installation. Two way butterfly valve is butterfly plate can face or back to the media flow direction, installation without attention to medium flow direction, in the valve body also does not indicate the direction of the medium flow arrow. Two way sealing butterfly valve stem force is greater than one-way butterfly valve stem. Design, the same diameter, pressure butterfly valve, two-way sealing butterfly valve rod diameter than one-way sealing butterfly valve stem diameter.
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:Do you use the straight stem butterfly valve in the fire fighting engineering?
Bar valve bar, did not hear the bar with butterfly valve, ah, there are pairs of folder and hand wheel type bar
Q:Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?
D stands for butterfly valve. 71 represents the clamp type, X represents the sealing surface material, and 16 represents the valve to bear the pressure 1.6MPA, C position is the valve body material code, omitted to represent gray cast iron valve; C represents the valve body material is carbon steel.
