Q:Butterfly valve general use occasions
Butterfly valve general use occasions:1 、 soft sealing butterfly valve applies to ventilation, dust removal pipeline two-way opening and closing and adjustment, metallurgy, light industry, power, petrochemical systems, gas pipelines and waterways.2, metal sealed double eccentric butterfly valve, suitable for heating, steam, water and gas, oil, acid and other pipelines, as the adjustment and closure devices.3, metal seal three eccentric butterfly valve, in addition to as large pressure swing adsorption gas separation control valve.4, metal seal three eccentric butterfly valve, can be widely used in petroleum, chemical, metallurgy, electricity, food, medicine, water supply and drainage, gas transportation and other fields.
Q:What does butterfly valve nps12cl150d373f4-150lb stand for?
NPS (Nominal, Pipe, Size) abbreviation. Refers to the connection (including flanged and welding end) of the nominal diameter, followed by a digital unit is American Standard inches, 12 inches.NPS12 labeling system.CL is the abbreviation for class, and LB150 means the pressure is 150 poundsD stands for butterfly valves3 is expressed in the form of a turbine drive7 means of connection: to clip3 means sealing: 3 eccentricF4: the sealing material is PTFE
Q:Butterfly valve use
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 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.
Q:What's the size of the signal butterfly valve sleeve?
The output signal is stable and reliable for a long time. The valve has an electric node, which is drawn out to the control center by signal line, and the signal line voltage is 12V. In fact, the valve is open and closed, there is a signal to the consumer control center, easy to monitor, the valve in addition to the electric node, with the ordinary valve is not much difference, there are also signal butterfly valve. When setting a quota, cover a valve, and then set 13-156.Door closer, 7-194 and 13-1013.Fire phone 7-188.Fire radio 7-382
Q:How big is the butterfly valve with a diameter of 80?
With the 80 caliber 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 flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid.
Q:The difference between the electric control valve and the electric butterfly valve, respectively, the application situation
Both are powered by electric butterfly valves.The control valve must have the ability to accept external signal control. At the same time, control signals and valves through the medium flow must ensure a certain relationship.Electric control valve belongs to electric butterfly valve; electric butterfly valve butterfly valve including but not exclusively butterfly valve.Electric butterfly valve is a kind of electric control valve.There are many types of valve body, usually through the single seat, straight through two seat, angle, diaphragm, small flow, three pass, eccentric rotation, butterfly, sleeve type, spherical and so on 10. In the selection of control valve valve prior to the media, process conditions and parameters to control the process of careful analysis, to collect sufficient data to understand the system requirements on the control valve, according to the data collected to determine the type of valve to be used.
Q:Butterfly valves are widely used in 2.0MPa below the pressure and temperature of not more than 200 degrees of various media, right?
3. kinds of butterfly valve:According to the connection mode: flange type, clip type.According to the material of sealing surface, soft seal and hard sealing.According to the structural form, butterfly valves can be divided into the following types:Plate typeInclined plate typeOffset plateLever type4. butterfly valve features:(1) the structure is simple and the shape is small. The utility model has the advantages of compact structure, short structural length, small size and light weight, and is suitable for large caliber valves.(2) the resistance of the fluid is small, and when the valve is fully opened, the valve seat passage has an effective circulation area, so the fluid resistance is smaller.(3) open and close, convenient and quick, good adjustment performance, butterfly plate rotation 90 degrees can be completed headstock. By changing the angle of rotation of the disc, the flow can be graded.(4) the opening and closing moment is smaller, because the butterfly plate on both sides of the rotating shaft is basically equal to the medium, and the opposite direction of the torque is generated, so that the opening and closing is more labor-saving.(5) low pressure sealing performance, sealing surface materials generally use rubber, plastic, sealing performance is good. Limited by the material of the sealing ring, the pressure and the temperature range of the butterfly valve are smaller. But the use of hard sealing butterfly valve pressure and temperature range has been greatly improved.
Q:Is a valve gasket the same as a valve cover gasket?
Your car has 2 valve covers hence,2 valve cover gaskets. Not valve gaskets. Maybe one of the valve covers needs replacing? If the valve covers or gaskets need replacing your car will be leaking oil from under the hood.
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:Ok, My zone-valve is dead. How do i find/fix it?
You may have only one circulate pump on the boiler. If you want to check the zone valve there is a small handle on the valve you can lift up and this will open the valve manually. It will be found on the (usually) green valve on the return end of the copper pipe. It should have a red and white wire attached. If this is opened manually and you get heat you can replace the top half of the valve by twisting it off and exchanging it with a new one. I think they are around $35.00 bucks or so at Home depot. You can keep it open without and fear. This means you will only have a one zone boiler and all baseboard s will get heat instaed of being zoned
