The function of pump inlet and outlet valves
Thread Content
What are the functions of the pump outlet check valve, the globe valve, and the pump inlet globe valve respectively? I hope the experts here can give me some advice!
A stop valve is used to close the inlet and outlet during pump maintenance to prevent the medium from flowing out and causing leaks； Check valves prevent the medium from flowing backward, preventing the impeller from rotating in reverse and damaging the motor
Original poster, you can search the forum for posts related to valves; there are explanations in simple terms about the functions of various types of valves such as stop valves, gate valves, and check valves. I wonder if the original poster has a specific question?
The pump outlet check valve is designed to prevent abnormal shutdown of the pump, or situations where the outlet valve is not closed in time after shutdown, which could lead to backflow of the fluid and cause damage to the pump’s impeller and its locking mechanism, as well as shaft breakage – all of which can result in damage to the pump’s components and the motor as well. The stop valves at the pump’s inlet and outlet are valves that need to be closed in order to prevent the medium from leaking out when the pump requires maintenance or repair.
Don’t understand your question? The question is: what are the respective functions of the valves installed at the inlet and outlet of the pump? Should I ask about the functions and differences of valves such as check valves, globe valves, and gate valves? These are two completely different questions.
