Q:Automotive valve question?
a) The very end is the tip. Below that are grooves that the keepers lock into. This is actually the thinnest part. Below that is the rest of the stem. The general name for the largest part in total is the valve head. b) Surface sounds right. Hadn't really thought about it before. LOL c) Valve Guide. These can either be just a plain hole in the cylinder head material, or often they have bronze inserts. Plain Guides are often repaired by a process called knurling. d) Valves seal to the head by grinding each at the same angle, (usually 45 degrees) and then they are lapped which is where an abrasive compound is placed in between, and the valve is rotated. This matches the surfaces more closely yet. The parts that seal are called the valve face and the seat which is actually a separate part that is inserted into the head, and can be replaced. e) Oil is supplied to that general area, by either holes in pushrods that lubricate the rocker arm, or in the case of rockers mounted to a shaft, through the shaft. In the first case, oil is supplied by the hydraulic lifters. In the latter, the shaft pedestals are drilled for oil passages. In both cases, oil is present in the area, but is not applied directly to the valves. In fact, the job of the valve stem seal is to keep too much oil from getting in the guides. f) Usually the coolant flowing through the heads is enough to carry away the heat, although some hi-performance engines employ techniques such as hollow exhaust valves filled with sodium. Most normal valves are solid.
Q:bmw 740il pcv valve...................?
In front of the engine slightly to the left and lower area of the throttle valve. It is a round black plastic canister supported by a teardrop shaped rubber with a cable connector at the top and 2 hose connections at the opposite end of the cable connector which are perpendicular to each other. BMW calls it the tank vent valve.
Q:pro's and con's of mechanical valve vs tissue valve...?
Your initial respondant hit on the basic question - 1. A biologic valve which will need a least one replacement again sometime in your mother's lifetime (though maybe at that time a better alternative might be available). 2. A mechanical valve which has an unlimited lifetime but requires life-long and very careful attendant focus on taking anti-coagulation medication, lest she be at risk for stroke or complications associated with bleeding. On the positive, it typically never requires replacement. At this point, both valves are likely to do the job. I have ancedotally seen some unfortunate complications associated with biologic valves - but it may have to do with biologic valves being used more frequently as most individuals needing this surgery are older. (and therefore select the biologic valve more frequently) Having an open heart surgery is about as big of an operation as you can have and is never undertaken lightly - let alone thinking of making a decision to have several of these surgeries over a time. It is a highly personal decision which does not have a right answer. If your mother is very good about taking medication and getting follow-up blood tests, then a mechanical valve might be right for her. If she has multiple other medical problems and is generally of ill health, she might want to consider the biologic valve. Generally speaking, for a woman in her 40's, generally healthy, and generally good about following regimen, then a mechancal valve is probably the right way to go for her. I hope this is helpful. Good luck to you and your Mother.
Q:How much for a valve job 96 Camry???
The devil is indoors the extra advantageous factors. Is the motorized automobile indoors making use of variety the area you should look into. what variety homeowners. Any maintenance records. Is the unique distributors instruction manual secure. i'm going to have a Toyota mechanic placed it on a advance and look into under heavily. There are rubber boots that carry particular lubricants mandatory to the drivetrain that have a bent to crack and leak with age. Has the Air Cond plumbing been switched out to settle for the nice and comfortable variety refridegerant. Do the belts and hoses look right maintained? My advice is to bypass forward and stumble on extra present day variety with fewer miles. Older autos, even Toyotas with that many miles that have not been right maintained can develop right into a funds pit and pass away you stranded. making an investment extra funds now can advise saving multiple funds and subject indoors the destiny.
Q:what is a foot valve used in petrochemical companies?
A foot valve is placed at the bottom of a suction pipe, which could be used to drain a large container of liquid. The foot valve is a one-way valve (check valve) that prevents the liquid from draining back into the container.
Q:Question about bicuspid valve...?
About 1-2% of the population have bicuspid aortic valves, although the condition is nearly twice as common in males. It is more common than any other congenital cardiac anomaly. Bicuspid aortic valve has been found to be an inheritable condition, with a demonstrated association with Notch 1. Familial clustering as well as isolated valve defects have been documented. The incidence of bicuspid aortic valve can be as high as 10% in families affected with the valve problem. Other congental heart defects are associated with bicuspid aortic valve at various frequencies.(Wikipedia) The cause of this problem is unclear, but it is the most common congenital heart disease. It often runs in families.(MedlinePlus)
Q:Valve seat removal?
There are a number of procedures that can work, depending on the metallurgy of the head and the valve seat. Most hobbyists and many professional auto mechanics farm the job out to a machine shop, as part of an overhaul process, where the cylinder head is reconditioned, with new valve and valve spring hardware, and thorough de-carbonizing, along with machine work needed to ensure the completed head assembly is true in all dimensions, and ready for replacement on the engine. Here's a link to a page that discusses the process in detail:
Q:bent valve stem?
Valve stems don't usually bend unless the valve hits a piston. I am assuming the rod that was bent was a push rod. The 5.2 engine is not an interference engine, so a cam timing problem would not cause the piston to hit the valve. I suppose that if you way over reved the engine a lifter could have pumped up and at a very high RPM the valves may have floated causing one or more to strike a piston. Push rods do bend for a variety of reasons, but to have a bent push rod AND a bent valve stem I would need more information to give you even an educated guess. You have the head off so look at the top of the piston and see if it looks like it was hit by the valves. Take the head to a machinist and have him check it for cracks and damaged guides. Have him check the valve spring tension also.
Q:i wanted to know what is the actual difference between check valve (non return valve) and globe valve?
Check valves are designed to prevent back flow. A globe valve is used when the ability to throttle and control the flow is desired. The globe valve can be positioned at anywhere from 1% to 100% flow. This allows for very precise control over how much liquid will be allowed to flow through the valve. There is another type of valve called a gate valve. The gate valve can not be positioned with such precision as the globe valve and it is used when flow rate is not as important.
Q:leaky heart valve?
i have the same problem,they found it when i was 40 and that's been 10 yrs 10 yrs it has put me in the hospital 4 times.but feel good most of the time.good luck.
