Q:How big is the butterfly valve with a diameter of 80?
With the 80 caliber butterfly valve.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.
Q:can't locate freon intake valve for 03 jaguar?
There is no Freon intake valve for an 03 Jaguar. Freon is R12 refrigerant and the vehicle uses an R134a refrigerant system. There is also no such thing as an intake valve on any vehicle refrigerant system. There is a high pressure port and a low pressure port. To answer your question: under the hood. Any other information would likely endanger your life, since this is obviously a DIY question and you lack the knowledge to safely recharge your vehicle's refrigerant system. R134a refrigerant, if inhaled, can kill you. Do not turn a DIY project into a DIE project. Leave the complicated stuff to the professionals.
Q:Are all vacuum EGR valve the same?
Did you get that EGR valve from Cadillac dealership?? A lot of those aftermarket parts DO NOT LIKE Cadillac's!!!!!!!!!! I run into that all the time nor will we use any aftermarket parts due to the problems we have with them. Make sure that switch is working that controls the EGR valve. I have seen those fail also. You need access to a serive manual so you can command that switch on off check with a test light a vacuum gauge to make sure you are getting vacuum to that EGR Valve. Also, make sure that the ports are not clogged up with carbon, even check the pipe inside the throttle body opening, they should be clean inside those tubes !!!!!!!!!
Q:QUestion about Valves during cardiac cycle?
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:How do you draw the butterfly valve in the engineering drawing?
Butterfly valve there are many kinds of painting, mainly designed to draw on the staff, according to the design institute out of the icon.
Q:Why do you need two butterfly valves in the water well?
Check the water gauge and check valve on both sides to facilitate the maintenance and replacement of water meter and check valve.
Q:What's the use of fire butterfly valve?
Fire butterfly valve is the abbreviation of fire signal butterfly valve, which belongs to a kind of fire valve.Fire valve is an important accessory on the industrial and building pipelines. The fire fighting valve is composed of three parts: valve body, headstock gear and valve cover. Among them, the fire signal butterfly valve has the advantages of simple structure, reliable sealing, light opening, long life, convenient maintenance and so on. It is widely used in water supply and drainage, building, fire fighting systems, all kinds of pipelines, especially in fire lines.
Q:Butterfly valve sealing material has several?
Nine: X1 (natural food gum), X2 (Heipalen), X3 (ethylene propylene rubber), X4 (neoprene), X5 (Ding Qing X6 (rubber), wear-resistant rubber (FPM), X7), X8 (silicon rubber), X9 (heat resistant ethylene propylene rubber)
Q:Butterfly valve is the control valve?
The flow characteristics of butterfly valves can be approximately equal percentage characteristics, with the positioner can do adjust, is mainly used in large caliber, straight stroke control valve more than 200 volume weight will be great, it suggests using the butterfly valve.
Q:Butterfly valve D71X-16 and D71X-16Q what is the difference?
Q should be made up of their own, generally 16, behind the body material, C carbon steel, P stainless steel, etc., have not seen Q, and 16, no symbol behind, representing the cast iron,
