A butterfly valve consists of body ,stem ,disc , actuator (manual actuator, worm-gear actuator , aerodynamic actuator or electric actuator) , and wafer type butterfly valve can implement the process for turning on turning off and regulating the flow by the circumrotation of stem and disc that is droved by actuators.
1.Simple and compact construction. Small in size and light in weight. Easy transportation, installation and maintenance.
2. Quick 90 degrees on-off operation. Minimized operating torque ,energy saving.
3. Excellent sealing performance with no leakage. Long service life.
4. Wide selection of materials ,applicable for various media..
5. Flow curve tending to straight line. Excellent regulation performance.
- Q: Does the wet alarm valve group need to install the signal butterfly valve?
- The wet alarm valve group shall be equipped with 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;
- Q: When will Butterfly Valves be used?
- 3, there are anti-corrosion requirements of the pipeline, such as sewage, chemicals, etc.;4 、 pipes that regulate flow control requirements, such as quantitative systems;5, there are open and close, fast opening and closing requirements of the protection of the pipeline system, rapid cutting......
- Q: How can one - way sealed butterfly valves and two-way sealed butterfly valves be distinguished?
- Two way hard sealing butterfly valve:Two way butterfly valve on the valve body usually does not indicate the direction of the media arrow sign, in the design of two-way sealing butterfly valve stem force is greater than one-way butterfly valve stem. The same diameter, pressure butterfly valve, two-way sealing butterfly valve rod diameter than one-way sealing butterfly valve stem diameter. At the time of installation, the butterfly plate can face or back the direction of the medium, without considering the flow direction of the medium.
- 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: Butterfly valve general use occasions
- Butterfly valveAlso 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.
- Q: How is the lug butterfly valve connected to the flange?
- It is clip type butterfly valve.Connection way is to use butterfly flange flange.The sealing surfaces at the ends of the two rubber sealing rings are respectively butted with the welded flanges welded on the pipe; the two headed screws and the nuts are used for fastening.
- Q: How to calculate the size of the manual butterfly valve?
- [1] type code, transmission mode, connection form, structure form, sealing surface material or lining material, nominal pressure, valve body material, this is the most basic arrangement way now D341X-16C. [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.
- Q: Butterfly valve sealing material has several?
- Nine: X1 (natural food gum), X2 (Heipalen), X3 (ethylene propylene rubber), X4 (neoprene), X5 (Ding Qing X6 (rubber), wear-resistant rubber (FPM), X7), X8 (silicon rubber), X9 (heat resistant ethylene propylene rubber)
- Q: Butterfly valve structure and working principle
- The clip type butterfly valve is connected with the two pipe flange with a stud bolt. The flange type butterfly valve is provided with a flange on the valve, and bolts are used to connect the flanges at the ends of the valve to the pipe flange.
- Q: i just finished installing a sprinkler line for my lawn and i used anti siphon valves and 4quot; sprinkler heads. it says in the manual that it has to be at least 6quot; from the highest sprinkler. i think i made a mistake. i installed it 7quot; from the highest 'sprinkler line' . will i have a problem with that regarding the operation of the anti siphon valves and the sprinkler system itself?
- If the antisyphon valve is not leaking maybe you should focus attention on the main valve ( assuming it is a solenoid valve) to see if it closes completely. Another thing, if the irrigation zone is on an incline then the water in the system will drain to the lowest point. Sometimes it drains slowly causing the impression of a leaky feed valve.
