Rupture disks and pressure safety valves (psvs) are both types of relief valves. Rupture disks are thin sheets of metal that break at a designated pressure and can only be used one time. Pressure safety valves also relive at a specified pressure, but work by a spring and can relieve multiple times with little or no damage to the relief device.
The question is somewhat vague, but basically any valve that is operated with any form of electricity can be considered 'electro'. Esentually, it could be a simple on off type of valve whereby a coil designed to accept a certain voltage level and capable of handling a certain ammount of power (Voltage x Current) will form a magnetic field when the voltage is applied, and move an internal plug that either covers or uncovers an oriface, which will in turn open or close a valve. More involved 'electro' valves may have motors that will move a stem in a proportional way to open or close a port through a valve partially.
You need to know the torque the motor needs to produce to operate the valve before you can specify the motor. It's all about the amount of power that needs to be delivered to any application that is critical in specifying motors. Motors are rated according to the power needed, so once you have that, then you can select the motor according to rpm and power supply.
A rupture disc or blow out panel is a non-reclosing pressure relief device that protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions. Rupture discs are commonly used in petrochemical, aerospace, aviation, defense, medical, railroad,nuclear, chemical, pharmaceutical, food processing and oilfield applications. They can be used as single protection devices or as a backup device for a conventional safety valve; if the pressure increases and the safety valve fails to operate (or can't relieve enough pressure fast enough), the rupture disc will burst. Rupture discs are very often used in combination with safety relief valves, isolating the valves from the process, thereby saving on valve maintenance and creating a leak-tight pressure relief solution.
there is many, although i do not know, i can tell you one thing, most of the parts in the tank (holds all the toilet parts) are simple machines. There is exaggerated amounts of levers. many more but i don't know :) -sorry i don't have the answer but its better then a fake answer! no offense
dn/dt acts: 1)gcb open. 2)Turbine speed reference is less than 2800. 3)TSE margine less than 30k. 4)Actual speed is lees than 2800 5)ip valve passing during rolling
There is no difference between check valve and NRV, both are same
I believe that servo is motorized and solenoid is magnetically activated.
no you cant
They are just about the same
XV is shutoff valve UV is under control valve
The term cock and valve are used interchangeably in the English language. The term cock has in large been replaced with valve with no functional difference between the two.
In short, More Power.
The intake valve is bigger.
Globe is used for throttling
A positive EGR valve has purple fireflies on it.
a gate valve is a one way totally open or closed valve, a control valve is a variable valve.
more fuel gets in to cylinders for more power
