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: Butterfly valve common faults and treatment methods?: Three, summary:Only familiar with every detail of circulating water pump outlet valve and butterfly valve equipment, timely and thorough maintenance and strict debugging, to ensure the safety and reliability of equipment operation, to ensure the healthy and orderly operation of equipment.

Q: How can one - way sealed butterfly valves and two-way sealed butterfly valves be distinguished?: One way sealing butterfly valve is the front of the butterfly valve. When it closes, it must face the direction of the medium. The medium flows only in one direction, and the arrow on the valve body indicates the direction of the flow direction of the medium. Attention should be paid to the flow direction of the medium during installation. The two-way sealing butterfly valve is that the butterfly plate can face or back the direction of the medium, and the installation needs no attention to the direction of the flow of the medium, and the valve body also has no indication of the direction of the flow direction of the medium. Two way sealing butterfly valve stem force is greater than one-way butterfly valve stem. Design, the same diameter, pressure butterfly valve, two-way sealing butterfly valve stem diameter than one-way sealing butterfly valve stem diameter.

Q: 1st where is my zone valve? I have an old Burnham gas baseboard heater2nd What do I do?My last resort is calling a proffesional.: do mean you have an area in house that the heat isnt working in? if so try by passing the thermostat zone valve is that same as circulator pump its valve in the line to radiator usually near boiler has wires onit that go to thermostat should be a circulator pump for each thermostat

Q: How does the pneumatic butterfly valve control the angle of opening?: This is really not good, control seems to be pneumatic defects, can only rely on the feeling

Q: Should I connect the butterfly valve before and after the pump? Or gate valve?: The best pump outlet valve, because the valve opening control accuracy, no movement. Valve structure is strong, adjusting performance better than butterfly valve. The pump outlet needs constant switching and adjustment, so the pump outlet valve is suitable for gate valve.Life water system valve, it is best to choose the gate valve, strong and reliable, cut off the system to grasp. But the cost is higher, occupying more space.Choose 1 or 1.6, there is no principle requirements, because the water supply pressure of life is generally between 0.25-0.5MPA, can meet the requirements. Only 1.6 is more durable and stronger, but the price is higher.

Q: What is the working principle of the electric butterfly valve, and what's the difference between the butterfly valve and the butterfly valve?: What's the difference between a worm valve and a manual butterfly valve?The turbine can light and close the valve here. It is more labor-saving and reliable. It is closed and open. Manual operation is relatively difficult, but the manual action is very fast. Fast switching.

Q: Butterfly valve network and ordinary butterfly what is the difference?: 1. The butterfly valve of the pipe network adopts an eccentric structure. When closed, it has the function of closing and tightening. The sealing performance is reliable. After opening and closing, the cover is completely sealed, and the cover is completely out of contact, so as to ensure that the sealing surface is not damaged.2, the sealing surface is made of stainless steel, corrosion resistant, high temperature resistant, long service life. With two-way sealing function, medium flow is not affected by the installation restrictions (if only one-way control medium should be used to seal the installation direction) is not affected by a single space, can be installed in the any direction.

Q: What kind of butterfly valve is sd342x?: Sd342x: two-way double eccentric soft sealing butterfly valveS: two way pressureD: butterfly valve3: turbine operation4: flange connection2: double eccentricX: rubber sealProbably the shape is not so good in appearance,Double eccentric mostly elastic sealThree eccentric is multi-layer sealHope to be of help to youOpened valve Co., Ltd. on the production of butterfly valve

Q: What is the D37-10Q butterfly valve?: The model is too simple, right D37A1X-10QB1, D: valve, 3: turbine head, 7: on the vertical plate clamp, A1: type A, X: type of rubber seat, 10: nominal pressure valve Q: is ductile iron, B1: plate is made of ductile cast iron
