Aux 1 Unit 6 Q7

1 / 10

Which type of valve is commonly used as a relief valve on the air side of a compressor?

C) Spring-loaded pressure relief valve

A) Globe valve

B) Butterfly valve

D) Gate valve

2 / 10

What is the significance of the set pressure in a relief valve on the air side of a compressor?

C) It regulates the amount of air that the compressor can produce

A) It determines the maximum pressure that the system can safely handle before the valve opens

B) It controls the speed of the compressor

D) It sets the temperature of the air leaving the compressor

3 / 10

What should be done to verify the correct operation of a relief valve after it has been overhauled and reset?

B) The valve should be tested at the set pressure to ensure it opens and closes properly

C) The valve should be painted for identification purposes

A) The valve should be visually inspected without any testing

D) The valve should be installed without testing and monitored during normal operation

4 / 10

What material is typically used for the construction of the body of a relief valve on the air side of a compressor?

C) Wood

B) Brass or stainless steel

D) Copper

A) Plastic

5 / 10

How does a spring-loaded pressure relief valve typically function?

B) It opens automatically when the air pressure exceeds the spring tension, releasing excess pressure

D) It closes automatically when the pressure drops below a certain level

A) It remains open at all times to regulate air flow

C) It opens manually when the operator adjusts the valve

6 / 10

What is the primary function of a relief valve on the air side of a compressor?

A) To increase the air pressure in the system

D) To regulate the temperature of the compressed air

C) To filter out impurities from the compressed air

B) To prevent overpressure by automatically releasing air when the pressure exceeds a set limit

7 / 10

Why is it important to document the set pressure and any adjustments made during the overhaul of a relief valve?

B) To provide a record for future maintenance and to ensure safety compliance

D) To improve the valve's appearance

C) To increase the valve’s operating temperature

A) To ensure the valve is aesthetically pleasing

8 / 10

After overhauling a spring-loaded relief valve, what is the first step in resetting it?

C) Lubricating the valve with oil

A) Reinstalling the valve without adjustment

D) Testing the valve without any adjustments

B) Adjusting the spring tension to the desired set pressure

9 / 10

What role does the spring play in a spring-loaded relief valve?

B) It sets the pressure at which the valve will open by providing resistance against the air pressure

C) It regulates the flow of air through the valve

A) It filters the air before it is released

D) It controls the temperature of the compressed air

10 / 10

Where is the relief valve typically located in the compressor system?

D) On the cooling water line

B) On the discharge side of the compressor

A) On the suction side of the compressor

C) Inside the compressor motor
