Q:Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?
Are butterfly valves and check valves fitted together?Butterfly valve is nothing positive and negative ah!
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.
Q:Function of signal butterfly valve in fire sprinkler system
The signal butterfly valve is generally installed in two parts: floor level, dry pipe, flow indicator front end, trunk pipe, wet alarm valve, front end.Floor level pipe installation is a function of the signal valve, when the floor spraying system needs repair, close the valve, open the end of the floor drain, emptying the water in the spray system, maintenance; two is the sprinkler system is not allowed inside water, when the butterfly is closed, will transmit a signal to the the fire alarm system, fire alarm system receives a monitoring signal (so called signal butterfly valve), fire sprinkler system that the floor is anhydrous state, fast repair.Wet alarm valve at the front of the signal butterfly valve with the main floor of the main role of the butterfly valve, first, maintenance, and two is the prompt sprinkler system, there is a signal butterfly valve closed, should be repaired as soon as possible.
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 water supply pipe is the gate valve And on the cross dry pipe are the gate valve? To answer the 30
1, this is a good question, it seems that this has not yet made a unified standard requirements, a bit confused2, personal understanding of fire water supply pipe, pipe shall be installed on the valve, because the valve is fully open all closed features of fire control system is usually required is fully open, easy management features are obvious.3, fire water supply system is also useful to butterfly valve, but mainly signal butterfly valve.The signal butterfly valve is generally installed in two parts: floor level, dry pipe, flow indicator front end, trunk pipe, wet alarm valve, front end.Floor level pipe installation is a function of the signal valve, when the floor spraying system needs repair, close the valve, open the end of the floor drain, emptying the water in the spray system, maintenance; two is the sprinkler system is not allowed inside water, when the butterfly is closed, will transmit a signal to the the fire alarm system, fire alarm system receives a monitoring signal (so called signal butterfly valve), fire sprinkler system that the floor is anhydrous state, fast repair.Wet alarm valve at the front of the signal butterfly valve with the main floor of the main role of the butterfly valve, first, maintenance, and two is the prompt sprinkler system, there is a signal butterfly valve closed, should be repaired as soon as possible.
Q:My quot;check engine soonquot; light came on yesterday and soon after that I took it to the nearest Midas to have the diagnostic test run on it - they stated I needed an ERG valve. I have no clue what it is and was told that it could run $160. - $300. for my 1900 Astro van. what is an ERG valve? I have noticed that my van has a low humming sound when I'm driving it.
Exhaust Gas Recirculation It redirects a portion of the exhaust gasses from the exhaust manifold back into the intake manifold so they can be re-burned. This is part of the emissions system that has been used since the early 70's.
Q:What's the material of the butterfly valve seat?
Butterfly valve seat materials commonly used include EPDM (three yuan ethylene propylene rubber), NBR (Ding Qing rubber), PTFE (PTFE), metal sealing (cemented carbide).Their scope of application is..:1, EPDM (three yuan ethylene propylene rubber): excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor, color stability, electrical properties, oil and gas flow at room temperature. Ethylene propylene rubber products can be used at 120 degrees for a long time and can be used briefly or intermittently at 150-200 degrees centigrade.2, NBR (Ding Qing rubber): from butadiene and acrylonitrile was prepared by emulsion polymerization, nitrile rubber by emulsion polymerization at low temperature, excellent oil resistance, high wear resistance, good heat resistance, strong adhesion. Its disadvantages are poor resistance to low temperature, poor ozone resistance, poor electrical properties, and slightly lower elasticity.3, PTFE (polytetrafluoroethylene): can be used at 260 degrees for continuous use, with the highest use temperature of 290-320 degrees, low coefficient of friction, good wear resistance, and excellent chemical stability. It can not be injection molded and can be extruded or painted. PTFE's unique properties make it widely used in chemical, petroleum, textile, food, paper making, medical, electronic and mechanical industries and marine operations.4, metal seal (hard alloy): metal seal valve seat material has good resistance to high temperature, high pressure resistance, corrosion resistance and wear resistance, but the high requirements of the processing technology, the biggest drawback is the long time operation is easy to generate leakage.
Q:When will Butterfly Valves be used?
Butterfly valve has the advantages of simple structure, easy operation, small footprint and light weight;1, for the city water supply network in general, DN300 still DN300 valve, butterfly valve above, this installation is convenient (especially large diameter valve installation is inconvenient, the weight of large volume, big);2, there are sediment pipeline, such as powder, mud and other mixed substances;
Q:Does the wet alarm valve group need to install the signal butterfly valve?
Wet alarm valve at the front of the signal butterfly valve with the main floor of the main role of the butterfly valve, first, maintenance, and two is the prompt sprinkler system, there is a signal butterfly valve closed, should be repaired as soon as possible.
Q:What does the triplex of pneumatic butterfly valve mean?
Generally referred to as "triple parts" as if: filter pressure reducing valve, solenoid valve, with the valve position feedback switch..
