- Q: does it come in when you go over a certain rpm or do the valves change depending on how far you depress the throtle?
- The variable is the valve timing. The spark plug fires a split second before the piston reaches the top of the stroke, to give the fuel a bit of time to burn. But, the faster the piston travels in the bore, that split second gets shorter shorter. So the engine computer changes when the spark plug fires when the valves close, to maximize the power from each ignition stroke.
- Q: What does "D341X-16Q" mean?What do D341-16Q letters and numbers mean for butterfly valves?
- D - valve type code: Butterfly valve;3 - valve drive mode code: worm gear;4 - valve connection form code: flange;1 - valve structure type code: vertical plate type;X - seat sealing surface or lining material code: rubber;16 - nominal pressure value: PN1.6MPa;Q - body material code: QT400 - 15.
- Q: I am confused as to the answer of this question. Please help.Indicate the status of the mitral, tricuspid and semilunar valves (whether they are open or closd) during the various phases of the cardiac cycle. Discuss the pressure in each of the relevant chambers or blood vessels during the phases with reference to the opening or closing of the valves.
- A heartbeat is a two-part pumping action that takes about a second. As blood collects in the upper chambers (the right and left atria), the heart's natural pacemaker (the SA node) sends out an electrical signal that causes the atria to contract. This contraction pushes blood through the tricuspid and mitral valves into the resting lower chambers (the right and left ventricles). This part of the two-part pumping phase (the longer of the two) is called diastole. The second part of the pumping phase begins when the ventricles are full of blood. The electrical signals from the SA node travel along a pathway of cells to the ventricles, causing them to contract. This is called systole. As the tricuspid and mitral valves shut tight to prevent a back flow of blood, the pulmonary and aortic valves are pushed open. While blood is pushed from the right ventricle into the lungs to pick up oxygen, oxygen-rich blood flows from the left ventricle to the heart and other parts of the body. After blood moves into the pulmonary artery and the aorta, the ventricles relax, and the pulmonary and aortic valves close. The lower pressure in the ventricles causes the tricuspid and mitral valves to open, and the cycle begins again. This series of contractions is repeated over and over again, increasing during times of exertion and decreasing while you are at rest. The heart normally beats about 60 to 80 times a minute when you are at rest, but this can vary. As you get older, your resting heart rate rises. Also, it is usually lower in people who are physically fit.
- Q: I have 1993 Seville 4.9. I got a new EGR valve but it didn't help. I tested it with vacuum pump, it won't hold pressure at all, same with old one. Is that new EGR valve bad or just different type of EGR that vacuum pump won't work? Thanks!
- The first source, pages 20-22, lists all 9 basic types of EGR valves. Not all the types are vacuum operated, but check out #5 and #6 - they behave very differently from each other without a real live exhaust system connected to them.
- Q: What are the advantages of butterfly valves?
- D. sediments are not readily accumulated;The E. is compact and has little installation
- Q: What are the major disadvantages of butterfly valves?
- Also 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.shortcoming1, use pressure and working temperature range is small.2, poor sealing.Butterfly valve can be divided into bias plate, vertical plate, inclined plate and lever by structure. According to the form of sealing, can be soft sealed and hard sealed type of two. The soft sealing type usually adopts rubber ring seal, and the hard sealing type usually adopts metal ring seal.According to the connection type can be divided into flange connection and clamp type connection; according to the transmission mode can be divided into manual, gear drive, pneumatic, hydraulic and electric several.
- Q: What does the butterfly valve model d344h, d345h, d346h, d347h mean?
- According to the international standard of the letters and numbers apart to explain D344H D is a unit of butterfly valve, two unit 3 is driving mode: turbine, three unit 4 connection: flange connection, four unit 4 Structure: seal type linkage, five unit H sealing material: Cr13 stainless steelD345H compare yourself to the above. Unit 5 four is a sealed, single eccentric structureD346H four unit 6 is an unsealed center vertical plateD347H four unit 7 is unsealed double eccentricIn general, there is only one difference between them: the structural form is different!
- Q: My bike has now 6200 miles on the odometer. The manual says that a valve adjustment should be performed every 6000 miles. But the bike runs fine. Can I just have the valve checked or should I have them adjusted even though the bike is fine? What will happen if I just keep riding it?
- In reality, lots of bikes go their entire lives without a valve adjustment. In my opinion that is a great way to ruin a bike though. They have a maintence schedule for a reason. If a valve isn't seating, it can hurt performance and the valve will not be able to transfer heat to the head. That can burn a valve and cause detonation. You have to check valves to adjust them, and the labor for just checking will be nearly the same or identical to doing the adjustments. I do all my own wrenching, so money isn't really an issue, but if I were you, I would just bite the bullet and take it in.
- 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: e.g. a patient with a prosthetic aortic valve and a patient with a prosthetic mitral valve. Also, can you get stenosis of mechanical valves or just tissue grafts?Thanks!
