Q:What is it for? I was given a data set which is a result of antisurge valves testing every 2 seconds or so. (more than 1000 rows, measurements by time) I have no idea how to start analysis of the data like that. Can anyone help?
An anti-surge valve is a valve that automatically opens to produce a flow through a centrifugal compressor to prevent surging of the compressor at a low flow rate. At surge conditions, there is no forward flow in the compressor and the compressor shaft will move foreword and backwards against the thrust bearing. This is damaging to the compressor and causes a terrible noise, that once you hear a surging compressor, you will never forget it. On an air compressor, the surge control valve will discharge to the air through a muffler. For process gas, it will discharge to another part of the process. The answer to your question depends on whether the data relates to the flow through the anti-surge valve of the compressor. It could even be a record of how fast the surge control valve operates. Based on this, no one can give you an answer for certain. TexMav
Q:i have a 98 ford escort SE. oil spils out the dipstick. we think its the pressure release valve. sadly we dont know where that is. any imput would be great
do you change your oil regularly? you could have gunk restricting the oil galleys in your motor and as the oil pump does its thing with no other outlet cause the oil to flow out your dip stick... when you consider how important oil is to the motor there should not be a release valve.... that is a set up for failure... although i wouldnt put it past ford to do something like that... my opinion of course... i would take it to a shop that can flush your oil system... might be hard to find but theyre out there... good luck
Q:does my 96 accord have an oriface valve or the other kind of valve? if so where is it? because im pretty sure that is the problem with my a/c not being cold at all
It uses an expansion valve inside the evaporator assembly, part 11 in the first source. If the evaporator valve is not working the compressor will be damaged - by no oil if the valve stays closed or by slugs of liquid spilling out of the evaporator if it sticks open. Fortunately, orifices and expansion valves are very reliable. I bet a standard A/C service (about $100) will get you cool again. If you do anything to disturb the refrigerant loop (trying to charge it at home, trying to change refrigerant system parts) you will only spend more... probably a lot more.
Q:I am looking for a full valve guitar amp for around ?300.It needs to be loud enough to play with a quietish drum kit.Currently i have looked at an epiphone valve senior in both and combo and cab and head form. i have also looked at some smaller amps such as the vox ac4 but am a bit worried about its small size. any advice would be greatly welcome. many thanks in advance.
Well I have the Valve Jr. and the AC4. The AC4 is a good sounding amp, but even though it is only 1 watt less, the Valve Jr. is much louder. The AC4 is a great practice amp but not enough to jam with a drummer unless he is pretty quiet and you really crank the amp. Never heard one of the new Valve Sr. models but with all of the goodies they added it should sound really good. I had my Jr. modified but it still doesn't have all the cool stuff the Senior has. I think you would really like the Epiphone and at 20 watts you will be more than loud enough. My 5 watt Jr. will get very loud. All I own are low watt class A valve amps, it's the only way to fly!! The Marshall Class 5 might be worth looking at also.
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.
Q:As title.What's an easy way to remember: mitral valve leaflets are anterior and posterior leaflets; tricuspid leaflets are anterior, posterior, and septal (medial); aortic valve leaflets are left, right, posterior leaflets; pulmonary valve leaflets are left, right, anterior leaflets?It's easy to remember all but one valve (mitral) have three leaflets each. Physically aortic root sits behind pulmonary trunk, I guess that makes it easy to remember aortic valve has left, right, Posterior; and that pulmonary valve has left, right, anterior leaflets. Where I'm running out of ideas now is how to remember tricuspid has anterior, posterior and septal leaflets... Please help.Thanks.
The tricuspid valve has three leaflets which are thin and membranous with commissures that appear more like indentations than true commissures. The TV apparatus is similar to the mitral valve but has greater variability and thinner leaflets. The three leaflets are the anterior, septal and posterior leaflets, with the anterior and septal being larger than the posterior leaflet. TV= tricuspid valve tri-cuspid=3(three leaflets) leaflets=3leaflets Tricuspid: Having three flaps or cusps. The valve that is called the tricuspid valve is situated between the right atrium and right ventricle and permits blood to flow only from the atrium into the ventricle. The aortic valve in the heart also has three cusps. Tricuspid valve (Anat.), the valve, consisting of three triangular membranous flaps, at the opening of the right auricle into the right ventricle in the heart of most mammals; -- sometimes called the tricuspid valves, each flap being regarded as a valve. Take care as always
Q:I have checked this and ensured that the flow control is turned on. I have also found that:1. Valve works in manual mode2. Solenoid is getting electricity and water seems to be flowing in automatic mode but nothing is coming out of the sprinkler.I am not sure what could be broken as manual operation works and solenoid sems to be working. Any ideas?Thanks.

Q:my mechanic did a valve clearance check and said it was OK and when I asked him about the clearances he said that they were 6 thousands and 9 thousands however in my book the measurements are different they are as follow: ( i don't understand what he meant by thousands)inlet: 0.10~0.140.15~0.19 exhaust: 0.14~0.190.20~0.24so did he just make it up or did he get the wrong measurement.
Your guy was quoting clearances in thousandths of an inch: .006 and .009 or 0.15 and 0.23mm The spec in your manual is given in millimeters. Your exhaust valve clearance is at the upper end of the range, right where you want it. The intake is at the low end of the range. Clearances tend to tighten up as the valve seat wears with use. It's not clear to me why your book would have two specs for inlet and two for exhaust. Clearance specs are usually given for a cold engine. Perhaps the tighter spec is for a hot engine. Bean, I'm right about the whole thing. Valve clearances get tighter as the engine warms. They typically get tighter over time. If they get looser, there is some unusual wear going on.
Q:right after it come through the foundation. Should it be a gate valve?
Gate valves used to be the standard, but Globe valves had replaced them, and now Ball valves have replaced them. A ball valve is the type of choice these days. They have the best reputation for shutting off completely and have a VERY low failure rate. Al
