Q:what are the step i need to do so i can change the valve seals my truck has been smoky.,,, any websites i want todo it myself... 1989 chevy silverado 2500 350 engine 5.7L
if the engine smokes only when you have let it sit a little while(over nite or so) and then it clears up after a min. or 2 of driving...its the seals .chevy 305/350 are known for that
Q:How big is the butterfly valve with a diameter of 80?
Generally speaking, especially small caliber, the butterfly valve will not use the variable diameter. Therefore, the butterfly valve DN and pound class selection, according to the field pipeline flange DN and pound level.So, in a strict sense, the caliber of the butterfly valve and the diameter of the pipe have not much relationship.Specific to your pipe diameter, there are questions: 80 diameter refers to the outer diameter or inside diameter? Yes, there is no flange on the site. Do you need a pair of flanges to be supplied?
Q:Butterfly valve in the use of the difference? Caliber?
According to the function and use of the valve and butterfly valve, gate valve, small flow resistance, good sealing performance, the valve plate and the flow direction of the medium is the vertical angle, if the valve is not in place in the valve plate switch, wash medium on the valve plate of the valve plate is easy to fibrillation, according to valve seal damage.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. On the pipeline, mainly from cutting and throttling. 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 is the medium flow rate when the centerline butterfly valve is fully open?
On the pipeline, mainly from cutting and throttling. 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 meaning of butterfly valve d371po?
According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve3== transmission: worm gear7== connection mode: clip type1== structure: midlinePo== sealing surface material: lining PoPo== propylene oxide (PO)
Q:I got my timing belt done on a 1999 Civic Si on September 26 @ 113,699 miles. at 116,9xx miles I bent a valve on my third cylinder. How likely is it that the timing belt is the reason why this happened? I heard that if the timing belt is a tooth or so off, it could bend a valve. So is it likely that this could have happened? Anyway to check?
If it was a timing belt issue it woudn't have only been one cylinder. And usually if it's only off by one tooth, it just runs poorly. IT has to be off by quite a bit, or the belt has to straight up break to bend a valve,, if that happened it would have made a horrible clanging noise repeatedly before it eventually sputtered out. the 1999 Si revs to what... 8000 rpms? You didn't happen to miss a shift and over-rev the engine, did you?
Q:How does the pneumatic butterfly valve control the angle of opening?
The angle of the rotating shaft is controlled so that the angle of the butterfly valve is controlled. You just have a good electrical locator
Q:Butterfly valve common faults and treatment methods?
Three, summary:Only familiar with every detail of circulating water pump outlet valve and butterfly valve equipment, timely and thorough maintenance and strict debugging, to ensure the safety and reliability of equipment operation, to ensure the healthy and orderly operation of equipment.
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.
