- Q: D37A1X9-16CB1: what does this butterfly valve mean?
- The model is composed of 7 units, the types of valves (gate valve Z, J, L, Q ball valve, throttle valve, check valve and H valve, butterfly valve, connection mode (D) internal thread 1 thread 2, welding flange 4, 6, 7, the clamp (0) electromagnetic transmission mode 1 solenoid valve, hydraulic, electric and hydraulic turbine are 2, 3, 4 and 5 gears, bevel gear, pneumatic hydraulic, 6, 7, 8, 9) pneumatic and hydraulic, electric, structure (straight or DC type 7,1 on behalf of the center plate, vertical type A (A) and LT X9) on behalf of a sealant is heat-resistant rubber, kg 16 kg, C represents the body material of carbon steel WCB, B1 on behalf of the valve plate is made of ductile cast iron plating)
- 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: What is the principle of butterfly valve and check valve? Any difference?
