What is a Gimpel valve?

The Gimpel Electro-Hydraulic Trip Throttle Valve (EHTTV) is a microprocessor controlled trip-throttle valve, with a self-contained electro-hydraulic actuator. It is designed specifically for emergency shutdown and throttling on steam turbines.

How does a trip throttle valve work?

The design concept of the standard trip throttle valve is basically that of a globe valve with a stem nut that is mounted in a frame or bracket that is free to move. those where the valve plug is pushed onto the seat by the closing force, and. those where the valve plug is pulled onto a seat by the closing force.

How does Gimpel valve work?

The OOTTV is designed to use hydraulic pressure supplied by the turbine control oil system to compress a fully enclosed, large diameter trip spring. This trip spring allows an OOTTV to typically produce four to 10 times the closing force of a mechanical latch-type trip throttle valve during tripping.

What is throttle valve function?

: a valve designed to regulate the supply of a fluid (as steam or gas and air) to an engine and operated by a handwheel, a lever, or automatically by a governor especially : the valve in an internal-combustion engine incorporated in or just outside the carburetor and controlling the volume of vaporized fuel charge …

What is throttle valve in turbine?

Throttle valve or governor valve is a big valve at the inlet pipe of the turbine. It has the same size as inlet. In this manner the inlet mass flow of turbine will be controlled and in the result the speed and output power of turbine can be controlled.

What will happen if the throttle valve closed fully?

Even when your throttle body’s blade closes entirely, some air has to get through to the intake manifold. Otherwise, your engine would stall. This air flows through a special tunnel known as the idle air bypass. This bypass provides just enough air to keep your engine running while your car is in idle.

What is the main function of a throttle valve Mcq?

Explanation: The purpose of a throttle valve is to control the quantity of the air-fuel mixture and it is attached to the accelerator pedal.

What is the purpose of throttle valve?

In a conventional gasoline engine, a throttle valve is used in the intake manifold to reduce the power output for part-load operation. Varying the throttle position (TP) controls the amount of mixture (air + fuel) inside the engine, while the AFR is kept constant.

Can you clean a throttle body without removing it?

A throttle body is located between your air intake filter and piping and your intake manifold. The throttle body acts as a valve, restricting the amount of air that can go into the engine. The great part is that you don’t have to remove the throttle body in order to clean it.

How much does it cost to clean a throttle body?

The question is whether the service cost is worth it. RepairPal.com suggests that a throttle body cleaning costs between $226 and $290. What’s interesting to note is the price of parts: $6 to $12, the low estimate of which is about twice the cost of a can of CRC Throttle Body Cleaner at your average auto parts store.

What is the other name for the plug valve Mcq?

What is the other name for the plug valve? Explanation: Plug valve is also called as slim valve and is used for on/ off control but with little pressure drop.

Which valve works on electricity and not on pressure difference?

Explanation: Solenoid valve works on electricity and not on pressure difference.
