Q: We live in a four story sixteen unity apartment building. There are two radiators in our apartment. The on in the living room is large and we can't turn it on with out water coming out of the little valve on the end, which I am assuming is there to release excess pressure. It doesn't matter if we leave it on for an hour or two days—water still comes out. It has warped the wood below it.How can I stop this? I would really like to have heat on both sides of my apartment.Thanks!
Melvin S is correct. But check to see if the valve is closed first.
Q: The pump is working fine on the presta valve on my back tire, but it is not working on the other presta valve. It seems like the the presta valve isn't sticking out far enough out of the tube for the pump to be able to lock in on it. What could be causing this?
to apply the adapter, you need to first unscrew the presta valve, then placed the adapter on and pump up the tire, then take the adapter off and tighten the presta valve to close it. I consider the different answer that that's recommended to replace the tubes so as that the presta valve does not come aside. New tubes are inexpensive - approximately $6 or so. you need to purchase a spare, too, merely in case you flat. in case you do no longer understand the thank you to alter the tubes, your community motorbike save can do this for you and clarify the technique so as which you're able to do it your self interior the destiny and sell you the tire levers (and patch kit in case you want) you will ought to do it. reliable success!
Q: My question mainly pertains to Electric Motor-driven Motor Operated Valve Actuators.
The motor drives a gear operator on the valve and is limited in the degree to which it operates by a set of limit switches so it doesn't over run or over torqued the shaft. This arrangement typically also has another set of limit switches that indicate the open or closed position so the person controlling the valve will know its position. This type of operator is typically used on ball, butterfly or plug valves but can be used on gate valves.
Q: We have a wall mounted shower head as well as a ceiling mounted shower head. Suddenly the turning valve for the wall mounted head does not work, only the ceiling one does. Is this stripped. Can it be repaired with a marble wall? I have a photo if needed. Thank you ahead of time. Patrick
The mixing valve is in the handle that turns the water on. You don't need to take down the wall to get at it. The handle come off including any cover plate and the valve is right behind it. Be careful not drop/lose any screws or washers. They are small. The home center sells replacements for certain brands so get that information.
Q: How do you repack an osy valve? Where do you get the packing from? Do you have to shut down the water to do it?
where is i get the packing gland material
Q: Are all the valve created games tied together somehow? Except for TF2 like in portal 2 glados says she might start a hobby of reanimating the dead so is that left 4 dead?
no or i thinks GLADOS PRO PROPOSED
Q: I am modelling the production of phthalic annhydride and my process has a lot of FIC, LIC, PIC notations in circles on the connections. Moreover there are what i think are temprature and pressure notations in a square and a triangle. But most primarily what does a pneumatic valve do?
pneumatic valve is nothing but a valve which is operated with the help of high pressure compressed air. the can be thought of as an alternative of a metal spring... These could retract valves more quickly and reduce the possibility of piston-valve interference as long as pressure could be maintained. Additionally, the amount of seat tension required to keep a coil sprung valve under control results in greater peak lift loading, with added stress to the entire valvetrain as a result.
Q: Is there a relationship?
From personal experience yes it can. My mothers hemoglobin dropped down to 8.0. The Dr said it was because of her stenosis in her aortic valve causing her to bleed in her abdomen. She had her heart surgery and it came back up, just like the Dr said it would.
Q: The pig heart is better than our heart but the valves can be used to help us.
I have had heart surgery and they ruled out replacing my valve with a pig valve because they only last about 5 years. They replaced mine with a mechanical valve, and so far it's amazing! If they replace your valve I believe they basically cut out the defective one and sew in a new valve, animal or man made. If replaced with a pig valve you must be on anti-rejection medicine, and have it replaced every five years or so. With a mechanical one you have to be on blood thinners, but they assume (last I heard) they should last a minimum of 40 years, probably longer.
Q: This trumpet has been in storage in its casing untouched for about 5 years. I took it out and tried to play it but only air comes out and no sound. The 2nd and 3rd valves are hard to push down. What do I do to fix it? Thanks!
Dis is a pretty common problem. The valves are in the wrong valve case or they are turned aound in the case. Take each valve out and check the number...... most have a number stamped near the top, or on the part around the spring. Get them in the right place with the notch in the case matching the little peg on the side of the valve and all should be well. By the way, if you can't get a buzz on the mouthpiece the whole problem is you alone.
