The valve shaft drive the butterfly plate, butterfly plate do 90 degrees rotation. Butterfly plate flexible for opening and closing, no card acerbity, beating phenomenon, small torque.
- Q: How many kinds of butterfly valves are there?
- 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 flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid. 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.[structure]The utility model is mainly composed of a valve body, a valve stem, a butterfly plate and a sealing ring. The valve body is cylindrical and has short axial length and is internally provided with a butterfly plate.
- Q: Why anti condensation of aluminum alloy anti condensation butterfly valve?
- Anti condensation butterfly valve principle: the use of the high performance plate material, can effectively prevent the temperature of body parts, isolating the transfer medium in the pipeline, to the actuator and the connecting flange surface without dew.
- Q: Butterfly valve model D344H and D343 difference
- [1] D344H-10C DN400, D343H-10C DN400, to talk about the 2 types of butterfly valves in common: D on behalf of 3 Representatives is butterfly valve, turbine driven, 4 representative is in the middle of flange, representing 10 kg pressure, C is the representative of the valve material is cast steel, DN400 represents the valve diameter; say that there the difference of 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 type variable eccentric in fact, is 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: 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: What do D71, D371 and D341 represent in butterfly valves?
- D71 stands for middle line to clip butterfly valveD371 represents the worm wheel centerline pair clip butterfly valveD341 stands for worm gear flange butterfly valve
- Q: What are the advantages of butterfly valves?
- Butterfly valve, also known as shutter valve, its advantages are:A. has a large circulation capacity and is about 1.2 times the same size as two seat valves;
- Q: What does butterfly valve do?
- Butterfly valve (English: butterfly valve) refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closure of a valve, the main cut off on the pipe 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. Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear. Using worm gear reducer, not only can the butterfly plate have self-locking ability, so that the butterfly board stops at any position, but also can improve the operation performance of the valve. Industrial butterfly valve features, capable of high temperature, applicable pressure range is higher, the valve nominal diameter is large, the valve made of carbon steel, the valve plate sealing ring using metal rings instead of rubber rings. Large high temperature butterfly valve welded by steel plate, mainly used for high temperature smoke duct and gas pipe.
- Q: What is the meaning of American Standard butterfly valve B series
- American Standard flange connection is divided into A, B series. A series for normal flanges, B series for compact flanges. 24 "to no AB series, flange standards for B16.5, 24" above B16.47.
- Q: Butterfly valves are widely used in 2.0MPa below the pressure and temperature of not more than 200 degrees of various media, right?
- First of all, is not the butterfly valve butterfly valve.Butterfly valve in the valve around the fixed axis rotating valve, called butterfly valve.1., as a sealed butterfly valve, it has been developed rapidly since the appearance of synthetic rubber, so it is a new type of shut-off valve. In our country until 1980s, the main role of butterfly valves in low-pressure valves, valve seat using synthetic rubber, by 90s, hard seal "metal seal" butterfly valve to rapid development. There are a number of valve factory can produce steady pressure metal seal butterfly valve, butterfly valve shall be shipped to a broader area.2. butterfly valves can transport and control the medium with water, condensed water, recycled water, sewage, sea water, air, gas, liquid gas, dry powder, mud, fruit pulp and a mixture of suspended solids.The domestic butterfly valve parameters are as follows:Nominal pressure: PN0.25 - 4.0MPaNominal diameter: DN100 - 3000mmWorking temperature: less than or equal to 425 DEG C
- Q: What is the difference between the installation and function of a butterfly valve and butterfly valve?
- Therefore, the fully open position of the valve is determined by the position of the gate. Some gate valve, stem nut is located on the gate, the handwheel rotates to drive the stem to rotate, and make the gate lift, this kind of valve is called rotary bar gate valve, or call dark rod gate valve. The type of gate width, sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate type valve can be divided into: single gate type, dual gate plate and the flexible gate type; parallel gate type valve can be divided into single and dual gate gate plate. According to the thread position of the valve stem, can be divided into two kinds of open rod gate valve and dark rod gate valve. Valve installation and maintenance should pay attention to the following: hand wheel, handle and transmission mechanism are not allowed for lifting, and is strictly prohibited. Double gate valve should be installed vertically, that is, the valve stem is in a vertical position, and the handwheel is at the top. The gate valve with bypass valve shall be opened before opening to balance the pressure difference between inlet and outlet and reduce the opening force. The gate valve with drive mechanism is installed according to the instruction of the product instruction. If the valve is constantly switched on, lubricate it at least once a month. The valve has the advantages of small fluid resistance, the sealing surface by the erosion of small and medium Chong brush. Opening and closing is more labor-saving. Medium flow direction is unrestricted, no disturbance, no pressure reduction. The utility model has the advantages of simple shape, short structural length, good manufacturing technique and wide application range. Valve faults between the sealing surface can lead to erosion and abrasion, maintenance more difficult. Larger size, open need a certain space, long opening and closing time. Complex structure.
