Q:If I flush the toilet the drama begins. While the toilet is flushing, if I lift the lift of the lid of the tank cover NOT THE SEAT, water shoots up straight in the air from the top/cap of the fill valve. This is a picture of a toilet fill valve.

Q:Friends,is there anyone know about LinX(Linear Exchage)Valve,how they work.thanks in advance
A valve is a device that regulates the flow of substances (either gases, fluidized solids, slurries, or liquids) by opening, closing, or partially obstructing various passageways. Valves are technically pipe fittings, but usually are discussed separately. Valves are used in a variety of applications including industrial, military, commercial, residential, transportation. Plumbing valves are the most obvious in everyday life, but many more are used. Many valves are controlled manually with a handle attached to the valve stem. If the handle is turned a quarter of a full turn (90°) between operating positions, the valve is called a quarter-turn valve. Butterfly valves, ball valves, and plug valves are often quarter-turn valves. Valves can also be controlled by devices called actuators attached to the stem. They can be electromechanical actuators such as an electric motor or solenoid, pneumatic actuators which are controlled by air pressure, or hydraulic actuators which are controlled by the pressure of a liquid such as oil or water. Actuators can be used for the purposes of automatic control such as in washing machine cycles, remote control such as the use of a centralized control room, or because manual control is too difficult; for example, the valve is huge. Pneumatic actuators and hydraulic actuators need pressurized air or liquid lines to supply the actuator: an inlet line and an outlet line. Pilot valves are valves which are used to control other valves. Pilot valves in the actuator lines control the supply of air or liquid going to the actuators. The fill valve in a commode water tank is a liquid level-actuated valve. When a high water level is reached, a mechanism shuts the valve which fills the tank. In some valve designs, the pressure of the flow fluid itself or pressure difference of the flow fluid between the ports automatically controls flow through the valve. In an open valve, fluid flows in a direction from higher pressure to lower pressure.
Q:I want to find a cheap valve that will let me take a breath in from one place then exhale through a tube going out so that i can attach an airbag to the breathing end and make a little diving lung.
Creating a proper valve system for the creation of a diving lung is not as simple as you think. You require carefully balanced directional pressure regulation valves. A simple one-way valve (AKA check valve) would remain open and release all the air from the airbag as soon as the airbag was subjected to water pressure.
Q:any flash files explaining valve operation maintenance will be very much helpful
A pressure relief valve or safety valve is used in pipe lines or any other pressure vessel (pressure cooker for eg) where pressure exeeding the strength of the metal of the container or the pipe has to b avoided to prevent failure of the metal or possible explosion.in a pressure relief valve the inlet of the valve is connected to the pressure area where as the outlet is connected to atmosphere.the valve lid is held against the pressure via a compression spring.when the pressure in the pipeline or pressure vessel exceeds the spring pressure the valve lid opens and the pressure is relieved.
Q:How are they different from other valves ?
Test valves are typically needle valves but I have seen some occasional usage of 1/4 to 1/2 inch globe valves and ball valves used as test valves for sampling. Pressure gauge installations may have test valves installed just below them. The valves are used to isolate the gauge from the system pressure, a second valve is used to vent the trapped pressure so the gauge could return to zero. The same vent valve could then be used to attach a calibrated pressure source to the pressure gauge so as to check (qualify) the gauge reading against the standard. This was done on select gauges where a quick in place qualification could be done without the need to physically remove the gauge from the gauge board. I have also seen test valve setups in systems using a three way valve in a setup to scavenge the sensing line with a clean fluid. This is done when dealing with a slurry which could block the sensing line suach as in a quick lime system. Clean water would flush the line before and after a reading so as to not trap material in the sensing line which could build up and block or cause a false reading. Test valve location also gives a handy mean to obtain a sample of the process fluid.

Q:compare the structure of the tricuspid valve with that of the pulmonary valve??please help me
Pulmonary Valve Structure
Q:I'm going to replace a valve guide and wondering how I should do it.Should I drill into the existing valve guide to the point it's small enough to pinch with some pliers and pull it out?When I put the new one in, should I use a wooden dowel and an air nailer to pound the guide into place?The more info. the better. It's my first time doing this.Thanks!
Ohhhh man. NO DRILLS. I assume you are referring to an Aluminum Cylinder head. To do it correctly you need a drift punch that has a pilot size of the valve stem, and an outside diameter that is just a few thousands smaller than the guide. Disassemble the head completely, put in Moms oven at the highest setting it will go to ( 5-6 hundred degrees ) Pound old guide out from the combustion camber side. ( have every thing ready to go this FFer will be hot ). Coat new guide with something like STP, put in freezer, carefully align it, then slam it home from the valve train side, don't pussy around, get it in before it attracts the heat of the head, if you stop or it stops you will have to repeat the entire process. If you gall the Aluminum ( say O-**** ) Since you have to hit this thing fairly hard you will need to refinish the inside of the guide with the appropriate reamer. Then refinsh Valve seat ( they never, NEVER line up perfectly )
Q:If you suffer from Heart Valve Disease why do you get tired or struggle breathing?
There are four valves in the heart. (Bicupid valve and aortic valve in the left side and tricuspid valve and pulmonary valve in the right side). You have not stated which valve is affected. Valvular heart disease may cause shortness of breath (dyspnea) and heart palpitations. You may need surgery if your valve does not work properly. * A valve that does not close all the way will allow blood to leak backwards. This is called regurgitation. * A valve that does not open fully will restrict blood flow. This is called stenosis.
Q:school starts tomorrow that means having band and i havent played it in 2 months (summer vacation) and i oiled the valves and the 1 and 2 valves are stuck the 1st valve comes up slowly when i push it down but on the 2nd valve it stays down how do i undo this???? thank you
You could just get a screwdriver and drill it into the bottom of the valve till it comes out. Its not damaging anything because there are no air pipes going through the bottom .
