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:Does the wet alarm valve group need to install the signal butterfly valve?
two is the sprinkler system is not allowed inside water, when the butterfly is closed, will transmit a signal to the the fire alarm system, fire alarm system receives a monitoring signal (so called signal butterfly valve), fire sprinkler system that the floor is anhydrous state, fast repair.
Q:The difference between vertical and horizontal butterfly valves in municipal water supply
Vertical and horizontal only installation directions and installation methods are different. Functionally, there is no difference.The main difference between the two methods of installation is that:1. horizontal can effectively avoid the high temperature radiation above the pipe. The disadvantage is that it takes up a lot of space.The advantage of the 2. vertical is that the occupation space is smaller, and it is easy to install. If the pipeline is higher, it is not convenient for maintenance.
Q:What does "D41X-16" mean?
GB case, D is butterfly valve, 4 is flange connection, 1 refers to the midline structure, X is sealed form for three yuan, ethylene propylene rubber seal, and 16 is the pressure of 16 kg.
Q:Butterfly valve structure and working principle
How it works: the disc is driven by the stem, and if it turns 90 degrees, it can be opened and closed once. By changing the deflection angle of the plate, the flow of the medium can be controlled. There are two kinds of butterfly valves commonly used: clip type butterfly valve and flanged butterfly valve.
Q:Butterfly valve switch direction respectively?
If it is not to sound from behind, from large to small if that is in the open.
Q:HOW TO CHANGE THE PCV VALVE HOSE?
So, the rubber elbow hose has a hole in it. Your best bet is to get the replacement from the Ford dealer. Yes, you can buy just the elbow part from the parts counter at the dealer. If they start acting all dumb (and won't help you or sell you the part) then, go to a different dealer for the part. Another thing you could try is a used one from the junk yard BUT, it's been my experience that the rubber gets too hard and the PCV valve needs a lot of encouragement to be removed. Sometimes you'll damage the used elbow by trying to get it off of the engine or removing the old PCV valve to put in your replacement valve. That's why I recommend getting a new one straight from the source. They are pretty simple to change with ordinary hand tools and some mechanical know-how. You just pull the elbow off of the port that it's attached to on the engine. The valve will probably have a steel clip that goes around the hose at one end of the valve inside of the hose. You simply squeeze the clip with a pair of pliers and tug at the valve until it comes out of the elbow.
Q:How does PLC control butterfly valves?
PLC control butterfly valve, usually control pneumatic butterfly valve or electric butterfly valve.PLC control pneumatic butterfly valve, that is, PLC program control, electric control, gas control, gas control butterfly valve;PLC control electric butterfly valve, that is, PLC program control electric, electric control butterfly valve.Control requirement:All PLC output contacts must be isolated from the intermediate relay and indirectly controlled by an intermediate relay.
Q:Butterfly valve D71X-10 and butterfly D371X-10 what is the difference?
One more 3 in D71X-10 stands for adding a worm gear to the valve. What are the same, the difference is driven by the handle into the drive, gear drive, worm gear drive for large caliber butterfly valve a little less, because the valve torque is big, big, hard to handle and can rotate, and if the worm, you can turn a few laps handwheel. If there are other questions, we can continue to ask questions, the city butterfly valve manufacturers
Q:Transformer butterfly valve and pressure relief valve difference
I don't know. Let's have a Baidu! Baidu is powerful.
