What is a pneumatic solenoid operated spool valve?

spool valveA spool valve is a multidirectional hydraulic or pneumatic valve usually operated by a joystick. It has several hoses attached to it leading to different pneumatic rams. When the joystick is pushed in one direction, it causes the valve to shut off one of the pneumatic hoses leading to the ram and open the other. Which way the joystick is pushed moves the piston in the ram in or out. Since you specified a solenoid operated valve it is operated not by a joystick that is directly connected to the valve but rather an electric joystick like the you would use in a video game and an electrical signal is sent to activate a solenoid that does the same thing but can be much farther away from the operator.

Solenoid Actuated Pneumatic Spool Valve

A solenoid actuated pneumatic spool valve is a spool valve actuated by an electric solenoid. They are often used in industrial automation and are usually controlled by a PC or a PLC (Programmable Logic Controller) rather than a manual switch. To reduce the size and power consumption of the solenoid, often the solenoid does not directly actuate the spool. Instead, the solenoid actuates a small internal valve which directs upstream air pressure to move the spool. This is called an air piloted solenoid actuated pneumatic spool valve. The air pilot mechanism typically requires about 40 PSI to operate reliably. If the air pressure upstream of the valve is going to be less than 40 PSI, the valve must be externally piloted, meaning that the pilot is connected to a separate air source which is above 40 PSI.

How do you draw a Ferris wheel in picture form?

First, you draw a circle, then you draw a another circle bigger than the first one. You draw a long rectangle at the bottom of your circles, then you draw ten smaller rectangles which are your carts. Make sure that your first circle goes through your carts. Next is detail. Curve the bottom of each cart. Then you draw tiny bulb shapes and the wire for your decoration. The wire will be just one line and your bulbs will look like ovals with curved points at one end. Then, if you want, you can draw humans in the carts. Trace over your long rectangle at the bottom of your unfinished Ferris Wheel. Don't trace too hard, because you have to draw a thick pole connecting the rectangle and the first circle. Now, draw yet another circle a little smaller than your very first circle to make the first pole of the actual Ferris Wheel. Then, go back to your carts and draw small poles to connect the carts, because you don't want the carts to fall down and kill all of the people inside of them. Now draw two lines next to each other, like, twenty times all over the first and second big circles to connect them. Draw ANOTHER circle smaller than your second big circle that you ever drew on this drawing to make the second round pole. Draw a circle in the very middle and then another around that to make another round pole. Draw lines connecting the first circle to the middle round pole and cover with wire and lights. Now, final step. Erase construction lines and clean up your final drawing, and there, person out of the wind, is your first Ferris Wheel. Now, if only you knew how to draw every other ride, than you'll have a carnival!

How do you jump rope?

Note: You don't have to read all of this information. If you just want to know how to single rope jump (jump roping by your self), then you only need to read the paragraphs with the stars next to them. If you also want to learn about jumping in the long rope, go ahead and read it all.

*Jump roping (single rope) is very simple. All you need is a jump rope or a heavy rope (not too heave or thick).

*To make sure the rope is the right size, step on the center of it, with your feet together, and pull each side strait up towards your face. If the rope comes up to about shoulder length, then it's the right size. If it's way under your shoulders or if it goes too high, like above your head, then it's too short or too long.

*The first thing you have to do is hold each end of the rope in each hand with the rope behind you. Then, with your elbows in, swing the rope over your head and jump over the rope when it gets to your feet. I prefer, when you're about to jump over the rope, begin to jump over it when the the rope comes to eye level. That way, when the rope gets to your feet, you don't jump over it too late.

*People who don't jump rope for a living, or don't have a good experience about jumping rope, they usually double bounce. Double bouncing is what most children do when they are jump roping. It's when you bounce two times before you jump over the rope. Pro jump ropers, like myself, don't double bounce, unless , sometimes, when they are jumping in a long rope. Otherwise they single bounce. That's when you bounce/jump only one time before you jump over the rope. When you are doing skills or tricks with a jump rope, you should single bounce. If you do it while single bouncing, it's going to be harder to do and it won't look good.

If you're jumping with a long rope, it involves three people, or two people and a doorknob. Two people will turn the rope and the other person jumps.

Here is how you do it, but you probably already know how:

Each person holds one end of the rope, except for the jumper, and they stand far apart, across from each other, and turn the rope at the same time. (Tip: Turn the rope in big circles, still with your elbow in, so that jumper can jump over the rope better. Also, don't stand too close or too far apart from each other or the jumper will have a hard time jumping over the rope. One last thing, make sure you are not turning to fast or too slow or the rope will not cooperate correctly.) Then, the jumper can either jump in or start in the middle of the rope and jump every time the rope comes to their feet. (I prefer you double bounce for this).

If you only have two people and you want to long rope jump, one person can turn the rope, and the other turner can be replaced with a door knob or another waist high object. You just have to tie the other end of the rope to the doorknob.

I hope this information helped you on how to jump rope.
