Q:How do you explain A in butterfly valve D37A1?
Represents a seal or lining material symbol.Said sealing ring or lining material with the Chinese phonetic alphabet: B Babbitts D nitrided steel, acid resistant stainless steel H, J L Aluminum Alloy, hard rubber, nylon NL, P leather, SA PTFE, SC PVC, SD bakelite, T copper, TC enamel, X rubber, Y hard alloy
Q:What kinds of butterfly valves are available? What is the working principle of butterfly valves?
According to the form of sealing:(1) forced sealing butterfly valve.1) elastic sealing butterfly valve. The pressure of the valve seat, seat, or plate is produced when the seal is closed by the pressure from the valve.2) additional torque seal butterfly valve. The seal is produced by a torque that is applied to the valve shaft.(2) pressure sealed butterfly valve. The pressure is greater than the pressure on the seat or plate.(3) automatic sealing butterfly valve. The pressure of the seal is automatically generated by the pressure of the medium.Divided by work pressure:(1) vacuum butterfly valve. Working pressure is lower than the standard atmospheric pressure butterfly valve.(2) low pressure butterfly valve. Butterfly valve with nominal pressure PN<1.6MPa.(3) medium pressure butterfly valve. Butterfly valve with nominal pressure PN 2.5--6.4MPa.(4) high pressure butterfly valve. Nominal pressure PN is 10. 0--80.0MPa butterfly valve.(5) ultra high pressure butterfly valve. Butterfly valve with nominal pressure PN>100MPa.

Q:How can the flange butterfly valve be installed on the pipe?
Outlet pipe configuration.If in the pipeline, the valve in order to do not bear the direction of the force and bending moment, it is best to set the valve at the exit side of the expansion joint. Valve opening and closing valve water pressure should not be borne by the foot, but through the valve flange, by the pipeline to bear as well.Butterfly valve structure is generally shorter length, and its butterfly plate will be extended to adjacent pipes or other parts, so be careful not to collide with other parts and interference. And to prevent the error matching pipe diameter greater than C and collide with the butterfly plate.Butterfly valve as a regulator, just adjust the flow and pressure. The valve is regulated by loss of pressure.
Q:Why anti condensation of aluminum alloy anti condensation butterfly valve?
High performance materials have a lot of outstanding advantages: such as low water absorption, corrosion resistance, insulation, cold insulation performance, etc., is 4 times the ordinary material butterfly valve.Anti condensation butterfly valve body adopts ultra light aluminum alloy valve body, its weight is only 1/3 of the traditional butterfly valve, the torque is small, the use and installation is convenient, and the corrosion is avoided.
Q:What do you mean, handle, butterfly valve, hard back and soft back?
The butterfly valve of the handle butterfly valve is installed in the direction of the diameter of the pipe. In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is between 0 degrees -90 degrees, when rotates to 90 degrees, the valve is fully open. This valve is mounted horizontally.Butterfly valve has an elastic seal and metal seal two types of seals. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.The hard back is the metal seal, and the soft back is the elastic seal.
Q:Buried extension butterfly valve is buried directly, or need to repair the valve well?
It is better to set up the valve well for repairing the valve later;If it is extended to reveal the valve well, the waterproof of the well must also be considered. Otherwise, a rainy well will be full.
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.
Q:D what's the meaning of "one 71x one 1 butterfly"?
According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve7== clip typeLinetype in 1==X== sealing surface material: Rubber-1== pressure rating: 1.0MPa
Q:Where are the exhaust valves, mud valves and butterfly valves?
The exhaust valve is suitable for the pipeline with working medium, so as to improve the efficiency of the water conveyance equipment and protect the pipe from deformation and rupture. Sludge discharge valves are suitable for use in floating waste water treatment plants, such as gypsum. Slag, scale power stations, smelters, sugar mills.
