Q:What is the national standard for clip butterfly valves?
GB/T 12238-2008 "flange and clip connection elastic seal butterfly valve"GB/T 26144-2010 flanged and clip on steel lined fluoroplastic butterfly valvesJB/T 8527-1997 "metal sealed butterfly valve"
Q:What is the working principle of the electric butterfly valve, and what's the difference between the butterfly valve and the butterfly valve?
General large bore turbine.What is the difference between worm gear pair butterfly valve and center line worm gear butterfly valve?The structure is the same, but the model is different, the central line refers to the butterfly valve, an eccentric structure (371), the clip butterfly valve can do 371, you can do 373, etc.. In more detail, the clamp can be a midline type, 1 single eccentric, 2 double eccentric, 3 is 371372373 midline, then it can be flange connection, it can also be a pair of clamp connection
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:The difference between gate valve and butterfly valve, as well as cut-off valve, what are their applicable conditions? Advantages and disadvantages?
The gate valve is one of the simplest valves. Generally manual, most of the electric valve failure, as a manual. Butterfly valve is more, I saw the pneumatic butterfly valve, that is, with gas control closed, general and solenoid valve matching.
Q:butterfly valves d7a1x5
D- valve type (butterfly valve), 7- connection mode (to clamp), A- valve shape mode (A), 1- structure form (vertical plate), X5- valve seat sealant species (Ding Qing, NBR)
Q:Butterfly valve model D373F-16C, ask God answers
D - butterfly valve, 3 - turbine rotation, 7- clamp type, 3- eccentric F - sealing surface for PTFE sealing, 16- bearing pressure 16KG, C - body material cast steel
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: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 "10" in the butterfly valve "D71X-10" mean?
The pressure of 10 kg 1.0MPA is usually cast iron
Q:Which is expensive, butterfly valve?
The same material and caliber, butterfly valve structure is simple, less wood, the price is much lower than the gate valve, especially for clip type butterfly valve.
