Q:Butterfly valve structure and working principle
Butterfly valve structure: Center to clip butterfly valve, single eccentric butterfly valve, double eccentric butterfly valve, three eccentric butterfly valve
Q:What's the difference between D71X-16 and D71H-16 butterfly valves?
D71X-16 and D71H-16 butterfly difference is that the cut-off is not the same, the latter is stainless steel seal, corrosion resistance, friction, acid or impurities can be medium fluid. The former is rubber sealed, only through the general temperature of the medium, not acid, with more, you can ask Luoyang crown Ning
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:Butterfly valve use
Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear. Using worm gear reducer, not only can the butterfly plate have self-locking ability, so that the butterfly board stops at any position, but also can improve the operation performance of the valve. Industrial butterfly valve features, capable of high temperature, applicable pressure range is higher, the valve nominal diameter is large, the valve made of carbon steel, the valve plate sealing ring using metal rings instead of rubber rings. Large high temperature butterfly valve welded by steel plate, mainly used for high temperature smoke duct and gas pipe
Q:How is the lug butterfly valve connected to the flange?
When installing, pay attention to the butterfly plate. The sealing ring between the flange face and the butterfly valve is tightened. After clamping, it can be tightened.
Q:Gate valve and butterfly valve which is installed when there is a direction?
Do not require frequent opening and closing, and keep gate fully open or fully closed. Not suitable for use as a regulator or throttling.Butterfly valve refers to the closure of parts (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 is fully open to fully closed is usually 90 degrees butterfly simple structure, small volume and light weight, only by a few parts. Moreover, the utility model can be rapidly opened and closed only by rotating 90 DEG, and the operation is simple.Is the gate valve opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Gate has two sealing surface, gate valve advantages: fluid resistance is small, opening and closing more effort, medium flow unrestricted, not disturbing flow, do not reduce pressure.
Q:Should I connect the butterfly valve before and after the pump? Or gate valve?
The best pump outlet valve, because the valve opening control accuracy, no movement. Valve structure is strong, adjusting performance better than butterfly valve. The pump outlet needs constant switching and adjustment, so the pump outlet valve is suitable for gate valve.Life water system valve, it is best to choose the gate valve, strong and reliable, cut off the system to grasp. But the cost is higher, occupying more space.Choose 1 or 1.6, there is no principle requirements, because the water supply pressure of life is generally between 0.25-0.5MPA, can meet the requirements. Only 1.6 is more durable and stronger, but the price is higher.
Q:whats the name of that valve under the kitchen sink?
Well definitely should not mess with it, especially if you do not know exactly what it is and more important what it controls. If not water, then it could possibly be the shut off for a near by gas appliance. It would help if you described the size and color of the pipe. Maybe you could try to trace it , where does it come from and where does it go to ?
Q:Butterfly D371X5-16ZB1 what does each letter stand for?
Daily valve pressThe regular model is out of step with you. I can only explain the regularD371X5-16ZB1D is butterfly valve3 is the turbine drive7 is the clamp connection1 is the display opening signX is a rubber seal16 is 16 kg pressureI don't know the other superfluous letters
Q:What's the difference between electric butterfly valve and electric two way valve?
The valve can only be fully open or fully closed, so the controller only need a 1/4 angle stroke in control, so you only need to open and closed position control. The butterfly valve can be opened and closed at any position within 90 degrees, so a positioning device is needed on the electric head. If the valve is used (such as double eccentric butterfly valve or three eccentric), due to the eccentric effect, need to always have a butterfly valve opening and closing positions to control the torque of Disc Edition in the stem, especially in the valve closed to non preferred direction needs a torque to ensure the butterfly valve, which requires control device to provide a torque to make butterfly valve position or seal. Therefore, the ball valve only needs to drive device to meet the opening and closing, two positions can be, and butterfly valve but in the switch of the whole trip in the control.
