- Q:so i'm replacing a one hole faucet, and i'm stuck at the very first step. the cold water valve turned off with no problems. i tried to turn on the cold water and none came out. unfortunately, the hot water valve just squeaks and goes around and around, never cutting off the water. when i turn it, it also leaks a minute amount of water, though regardless of which way i twist, it stops as soon as i do. i can't just unplug the hot water valve with it still running water, so does anyone have any ideas? how does one replace a valve like this to begin with? is it possible that there is a shut off valve for the house that i myself can access (without having to call someone to shut off my water)? in case you haven't noticed, i am a bit plumbing deficient, so if you could explain it without too much jargon, it would be much appreciated.
- There has to be a main shutoff in the house, whether you are hooked up to city water or have a pump. And no, when you shut off the main valve and the pressure drops very little more water will escape the water heater. If the water heater has a shut off valve on the hot water line coming out of it, even better. Shut one or the other/or both off and drain the pressure via the sink faucet. The only water you will get when you take the problem valve off will simply what is in the lines. You can then change the valve and faucet. It's always prudent to shut off the power, or flame if the the water heater is gas, in case there is a bit of syphoning.
- Q:Offcourse temp control valve controls temp, and pressure control valve controls pressure....and so on. I am wondering, what are the mechnical differences in the valves body and how are they operated in terms of process control.
- In principle all valves are flow control valves. What changes is the variable they are controlling. A temperature control valve controls a flow to heat or cool another fluid. A pressure control valve, controls a flow to maintain the pressure in a vessel. As pointed earlier, valves can be self contained, i.e., the sensor is part of the control mechanism, usually a diaprhagm which moves the valve stem. and a spring to adjust a set point. Or, they can be pneumatic or electronic, in which case there is an external power source, transducer and controller to adjust set point, gain, reset and rate. This gives additional flexibility, if needed, depending on the process to be controlled. .
- Q:I couldn't get a name off the valve as it sits. It has a leak on the top plate and i'd like to replace the valve plate as opposed to cutting the whole thing out and replacing.
- i have seen many types of valves on an everyday basis. and i havent even seen one like this. its most likely a cheaper knock off brand valve. you have enough room to replumb a new one in quite easily. if you do not have enough room right before the valve to just cut it out, cut the pipe on the other side and unthread the valve from the threaded fitting. then buy some fittings and pipe and replumb it. you have a lot of room to work on it. i doubt you will find the same valve to part it out with. use either a Hunter valve or a rainbird valve avoid toros, orbits, weathermatic, and lawn genie parts. good luck and just take your time.
- Q:What is a valve mismatch in cars. code 300, 302, 420. All togather. Mechanic is telling the truth to do tune up and all. Is iT valve itsef? What is a (bad) coild? MITSUBISHI MIRAGE 2000
- Wherever you are get out. You are about to be ripped off. This will probably be too late. I gather the code you gave is the trouble code, as they are called, from the cars obd. The code 300 is random / multiple cylinder misfire. The code 302 is cylinder # 2 misfire The code 420 is catalytic system below threshold bank # 1 Deciphered this means you have a spark plug misfiring in cylinder #2, bank # 1. The misfire is causing a rich gas mixture in the exhaust system that is detected by the sensor and therefore it says you have a catalytic converter problem. I would suggest you replace your spark plugs, if they have a lot of miles on them. Are they the original plugs ? I f so they are probably due. Get out of there and go find an honest shop that will not rip you off. Now that you know the problem they can;t cheat. I don't know what all that other valve business was about but all you have is a misfiring spark plug.
- Q:Can someone explain to me what lead and lag time are? Also, what are the three flow characteristics? Linear, equal percentage but what is the third. If I wanted to have a minimum stop at 25% on a non-linear valve such as a butterfly valve, how would I achieve this. Obviously you cannot just restrict the valve by 25% of its travel as it is not linear
- Hope this helps in some way... To start the 3 main flow characteristics of a control valve are Liner, Equal percentage and Quick opening (or fast opening). If you interested there are also other characteristics. As far as i am aware the lead time is the time in which a signal is sent to the valve and the lag time is the time in which the actuator moves and closes the valve. The pysical movement. As for your final question the only thing i can think of is to alter the actual size of the butterfly valve or put a reducer before it. Sorry if my information was of little use.
- Q:For instance, I am buying some new tires that don't have the valve stems on them, so could I remove my existing valve stems from my used tires onto the new tires? Is this recommend at all? Is it safe? Is it possible? Can this be done? why or why not? thank you.
- valve stems are part of the rim only, they cost only 1.50 at the parts store and a tire/service place will charge you 5 dollars on each or include them with the price of mounting and balancing. new ones are suggested always when you mount another tire
- Q:hi guys..What is different between globe valve and stop check globe? Is that stop check globe=SDNR JIS std?
- I am not even sure what you are talking about. a globe valve is a type of valve that can stop the flow by turn a handel on top of the valve. A check valve on let the flow go one way and stops the flow the other way. hope this help Globe valve From Wikipedia, the free encyclopedia Jump to: navigation, search A Globe valve is a device (specifically a type of valve) for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.[1] Globe Valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. This has an opening that forms a seat onto which a movable plug[2] can be screwed in to close (or shut) the valve. The plug is also called a disc or disk.[3][4][5] In globe valves, the plug is connected to a stem which is operated by screw action in manual valves. Typically, automated valves use sliding stems. Automated globe valves have a smooth stem rather than threaded and are opened and closed by an actuator assembly. When a globe valve is manually operated, the stem is turned by a handwheel. Although globe valves in the past had the spherical bodies which gave them their name, many modern globe valves do not have much of a spherical shape. However, the term globe valve is still often used for valves that have such an internal mechanism. In plumbing, valves with such a mechanism are also often called stop valves since they don't have the global appearance, but the term stop valve may refer to valves which are used to stop flow even when they have other mechanisms or designs. Globe valves are used for applications requiring throttling and frequent operation. For example, globe valves or valves with a similar mechanism may be used as sampling valves, which are normally shut except when liquid samples are being taken. Since the baffle restricts flow, they're not recommended where full, unobstructed flow is required.
- Q:I have a 87 cbr600, consumes oil at a considerable rate. Took the engine out of the frame and disassembled cylinder head, block and pistons and found there is a thick layer of cooked-on oil over all sixteen valves. I figured the oil consumption was due to bad rings, but could it have been the valves?
- just rebuild it since you have it a part 87 im sure that among other things was the problem im sure it was both
- Q:Mitral valve prolapse have impression on lifetime?please answer with source
- Mitral valve prolapse (MVP) is the most common heart defect in population. The prevalence of MVP is about 0.6–2.5%. The occurrence increases with age, and the highest is in young woman. MVP is diagnosed by transthoracic echocardiography when displacement of mitral valve leaflet(s) above the annulus into the left atrium during a systole is present (Fig. 1). The clinical symptoms of the disease are connected with instability of the autonomic nervous system. Fig. 1 Two-dimensional echocardiographic long axis parasternal view of mitral valve prolapse. MV mitral valve, LV left ventricle, LA left atrium, RV right ventricle, Ao aorta Such a large population of patients becomes a problem of social significance, and it is extremely important to determine the influence of MVP as a chronic disease on patients. That is why our trial to evaluate the health-related quality of life (HRQOL) in children with MVP was undertaken. There are many publications concerning MVP in adult patients, but no study on their quality of life has been found. The literature concerning HRQOL of children with heart defects is not very extensive; the authors analyzed the problem of patients with serious conditions, such as hypoplastic left heart syndrome, transposition of the great arteries, pulmonary atresia, tetralogy of Fallot and non-complex heart defects, like ventricular or atrial septal defect [1–3]. The aim of our study was to evaluate the quality of life of children with MVP and the impact of clinical symptoms on HRQOL. You will detailed information on the link given in sources, as it is long topic.
