- 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: The difference between butterfly valve and gate valve
- Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious.
- Q: Butterfly valve model D344H and D343 difference
- In fact, almost all refers to the sealed variable eccentric butterfly valve.1, D344H-10C DN4002, D343H-10C DN400Let's talk about the similarities between the 2 Butterfly models: D stands for butterfly valves, 3 represents turbine drivers, and the middle 4 represents flanged connections,10 represents the pressure of 10 kg, C represents the butterfly valve, the material is cast steel, and DN400 stands for the caliber of the valve;To say that where there are differences between the 2 models, there is a place where there are differences, second means 4 of the first models is the new type sealing valve structure is variable eccentric, second of the second models of the 3 represents the structure of the valve is three eccentric, and three eccentric seal variable eccentric type is in fact a meaning.Sealed three eccentric butterfly valve, sealed variable eccentric butterfly valve, corresponding to the central butterfly valve and sealed single eccentric butterfly valve.
- Q: Import electric butterfly valve which brand is more reliable?
- Recommend Sichuan Ding Heng petroleum machinery company sales agent SPM butterfly valve and FMC butterfly valve, we are partners for many years, have been working together are very happy.
- Q: The difference between the electric control valve and the electric butterfly valve, respectively, the application situation
- Electric butterfly valve is a kind of electric control valve.There are many types of valve body, usually through the single seat, straight through two seat, angle, diaphragm, small flow, three pass, eccentric rotation, butterfly, sleeve type, spherical and so on 10. In the selection of control valve valve prior to the media, process conditions and parameters to control the process of careful analysis, to collect sufficient data to understand the system requirements on the control valve, according to the data collected to determine the type of valve to be used.
- Q: What is the medium flow rate when the centerline butterfly valve is fully open?
- After inspection, the product certificate shall be attached to the factory.Butterfly: 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 air, water, steam, all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow.
- Q: What are the major disadvantages of butterfly valves?
- Rubber elastomer in the butterfly valve will cause tear, wear, aging, perforation and even shedding in continuous use. The traditional heat curing process is difficult to adapt to the needs of on-site repair. It is time-consuming and laborious to use special equipment when repairing, and it consumes a lot of heat and electricity. Nowadays, polymer composite method is gradually used instead of traditional method.
- Q: How is the lug butterfly valve connected to the flange?
- Lug type butterfly valve is also called a single flange type, that is, with a flange on the valve body, usually installed at the end of the pipe, and even the method is 1: double bolt lock on the valve body 2: into the flange 3: lock nut
- Q: What is the D37-10Q butterfly valve?
- It may be the D371, the turbine to the clip type soft sealing butterfly valve, from your model can also see that the pressure is 1.0MPa, the body is ductile iron. It could be the D373, the turbo clamp hard seal butterfly valve, which is more expensive than the soft seal.
- Q: What's the difference between electric butterfly valve and electric two way valve?
- The valve can only be fully open or fully closed, so the controller only need a 1/4 angle stroke in control, so you only need to open and closed position control. The butterfly valve can be opened and closed at any position within 90 degrees, so a positioning device is needed on the electric head. If the valve is used (such as double eccentric butterfly valve or three eccentric), due to the eccentric effect, need to always have a butterfly valve opening and closing positions to control the torque of Disc Edition in the stem, especially in the valve closed to non preferred direction needs a torque to ensure the butterfly valve, which requires control device to provide a torque to make butterfly valve position or seal. Therefore, the ball valve only needs to drive device to meet the opening and closing, two positions can be, and butterfly valve but in the switch of the whole trip in the control.
