Q:Butterfly valve model D373F-16C, ask God answers: D butterfly valve, 3 turbo rotating, 7 pairs clip type, 3 eccentric F PTFE seal, 16 nominal pressure 1.6MPA, C valve body material, carbon steel

Q:Butterfly valve in use when should pay attention to what problems?: After the last in the pneumatic butterfly valve after use, also need to be cleaned immediately after the valve is closed, should use soft cloth to clean the valve, which may have some impurities, dirt removal, and oil lubrication, so it can better guarantee the use of the next.

Q:The water supply pipe is the gate valve And on the cross dry pipe are the gate valve? To answer the 30: Crown valve pressThere is no standard answer to this question. I can only give you my personal opinionRiser butterfly valve is generally place in these places (the pump outlet valve, drainage system, upper and lower floors) riser are basically installed butterfly valve, butterfly valve is not cheap, fast speed is fast closing butterfly valve can be quickly closed and open educationYou see the water pipe installed valve (with all the cross tube is the basic gate) explanation, because in contrast to the quality and stability, the valve will be better, the site does not need fast switching, it will choose good stability point gateSum upThe drains are all butterfly valves, and the stabilizing pipes are all valves! (do not rule out a full use butterfly valve for stealing work)

Q:What are the uses and classifications of manually operated clip butterfly valves?: In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is 0 degrees -90 degrees between, when rotates to 90 degrees, the valve opens the card completely. Butterfly valves are not only widely used in petroleum, gas, chemical, water treatment and other general industries, but also applied to the cooling water system of thermal power stations.

Q:What does the model D373H-16C of butterfly valve mean?: D373H-16C said: D type butterfly valve butterfly valve 3 said, said 7 of the turbine, said clip, 3 said the three eccentric (swash plate), 16 C nominal pressure, said carbon steel. In fact, if you want to understand this, to understand the valve 3.07ghz, later met have to be attached to the valve. 3.07ghzModel for valves, valve number indicates valve type valve should normally be that type, drive type, connection type, structural features, nominal pressure, sealing surface material, body material and other factors. Standardization of the valve type of valve design, selection, distribution, provide more convenient. The type of valve types and materials are more and more more models of the preparation of the valve will become more and more complicated. Although the preparation of our valve type unified standard, but gradually can not meet the needs of the valve industry. At present, the valve manufacturer usually adopt a unified numbering; not uniform numbering, the manufacturer can make out no.methods according to their own situation. Unit two unit three unit four unit five unit six unit seven unit

Q:CAD drawing of butterfly valve: Your question is very international. Ha-haThis method of painting is not clear in one or two words.First you'll know the map, then you'll use CAD, so the two will add up.Guess you will.

Q:What is the medium flow rate when the centerline butterfly valve is fully open?: The pressure test of the central butterfly valve is carried out at each station.Basis：1) GB/T12238-2008 flange and clamp connection elastic seal butterfly valveRules: butterfly valve must be carried out by factory inspection and testing, inspection qualified before leaving the factory.2) CJ/T 261-2007, butterfly valves for water supply and drainageRules: each product shall be inspected by factory and quality inspection department.

Q:Gate valve and butterfly valve which is installed when there is a direction?: Do not require frequent opening and closing, and keep gate fully open or fully closed. Not suitable for use as a regulator or throttling.Butterfly valve refers to the closure of parts (butterfly plate) as the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve is fully open to fully closed is usually 90 degrees butterfly simple structure, small volume and light weight, only by a few parts. Moreover, the utility model can be rapidly opened and closed only by rotating 90 DEG, and the operation is simple.Is the gate valve opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Gate has two sealing surface, gate valve advantages: fluid resistance is small, opening and closing more effort, medium flow unrestricted, not disturbing flow, do not reduce pressure.

Q:Butterfly valve model D344H and D343 difference: [2]: 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 air water, steam, and all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow. On the pipeline, mainly from cutting and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.The answer is recommended by Gu Fengxiang, a member of the science education category

Q:Butterfly valve flow direction is single or two-way?: The arrow on the butterfly valve is the medium direction of circulation, generally double eccentric, and the three eccentric butterfly valve has the arrow in this direction.The butterfly valve, the valve direction and fluid flow direction should be consistent, we use the butterfly valve is in accordance with the arrow direction and flow direction of the installation.If the arrow is marked on the valve body, it must be installed in its direction. If it is marked on the handle, it means open. Depending on the internal structure, it is possible to have the installation direction required.
