Q:The difference between butterfly valve d71x_10s and d341s-10
Before distinguishing between the two, you must first read the identification of the valve type:D stands for butterfly valves,3 means that the worm gear is connected and the drive does not indicate the handle7 and 4 indicate pipe to clamp connection, pipe flange connection, respectively1 means single eccentric, that is, the stem is not in the center of the butterfly plateThe former S indicates the material name of the valve body - plastic, X means sealing and the lining material is rubberThe latter S indicates the sealing lining material code ---- plastic, and the valve body is cast iron.10 means stress.
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:Transformer butterfly valve and pressure relief valve difference
The oil immersed transformer pressure release valve is a safety device installed in the transformer, when the internal pressure is less than the limit value of the transformer such as 35kPa, which is in closed state, when the transformer internal fault occurs, a large number of transformer oil by pyrolysis, produce large amounts of gas, the internal pressure of the oil tank increased dramatically when the opening pressure exceeds the pressure release valve when the pressure relief valve opens, the internal oil and gas overflow, to release the pressure, avoid the pressure on the inside of the lead tank cracking or permanent deformation, when the fault of transformer internal end, internal pressure tank to reduce pressure release valve closing pressure, it will automatically shut down to prevent outside air enter the inside of the tank or water.
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 is the principle of butterfly valve and check valve? Any difference?
Crown valve pressButterfly valve is butterfly valveThe check valve is a check valveButterfly valve is mainly switching functionThe check valve mainly stops the pipe from flowing backwardsThe two can only be said to be valvesThe others are different
Q:Butterfly valve, two-way pressure and one-way pressure what is the difference?
One way sealing butterfly valve is the front of the butterfly valve. When it closes, it must face the direction of the medium. The medium flows only in one direction, and the arrow on the valve body indicates the direction of the flow direction of the medium. Attention should be paid to the flow direction of the medium during installation. Two way butterfly valve is butterfly plate can face or back to the media flow direction, installation without attention to medium flow direction, in the valve body also does not indicate the direction of the medium flow arrow. Two way sealing butterfly valve stem force is greater than one-way butterfly valve stem. Design, the same diameter, pressure butterfly valve, two-way sealing butterfly valve rod diameter than one-way sealing butterfly valve stem diameter.
Q:When will Butterfly Valves be used?
Butterfly valve has the advantages of simple structure, easy operation, small footprint and light weight;1, for the city water supply network in general, DN300 still DN300 valve, butterfly valve above, this installation is convenient (especially large diameter valve installation is inconvenient, the weight of large volume, big);2, there are sediment pipeline, such as powder, mud and other mixed substances;
Q:The difference between the directly buried gate and the flange valve and butterfly valve
The flange gate valve is stable and reliable when used in the pipeline, so the flange gate valve is used on the high pressure pipeline.Butterfly valve refers to the closure of parts (valve or 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 used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.
Q:How can the flange butterfly valve be installed on the pipe?
Direction.Butterfly valve in theory can be installed in any direction, it is recommended that the horizontal installation of the valve shaft installation, so that both ends of the bearings will not be at the bottom (below), so as to avoid sediment in the media into the bearing.Inlet pipe configuration.There are water inlet side valve elbow, tee pipe fluid caused by bending and uneven distribution of the inflow valve, the drift will occur in the pipe, so it must be generated by the uniform drift disposed on both sides of the disc, so as to avoid uneven force on both sides of the disc, and may produce additional torque.
Q:Butterfly valve switch direction respectively?
First, if the butterfly valve has been installed on the pipe, you can first see the mark on the handwheel. Second, there is a switch indicator on the general worm gear.
Our valve is widely used in petroleum, chemicals, power, metallurgical, pharmaceutical and other industries.Our campany insists on surviving on high quality, creating with science and benefiting from management.
