Q : The main features of the stainless steel butterfly valve?
A : 1. Small and lightweight, easy to disassemble and repair, and can be installed in any position. There are two types of connection between clip and flange. It can also be equipped with a flanged shrinkage, called an inlet flanged telescopic butterfly valve, which prevents the pipe from expanding and shrinking.
2. The structure is simple and compact, and the 90° rotation opens quickly. It can be powered by electric or pneumatic, called imported electric rubber-lined butterfly valve and imported pneumatic butterfly valve for remote control.
3. The operating torque is small, labor-saving and light.
4. The flow characteristics tend to be straight and the adjustment performance is good. Can be used for adjustment.
5. The number of opening and closing tests is up to tens of thousands of times and the life is long.
6. The seal can be replaced, the seal can bebidirectionally sealed, and the gas test leak is zero. It can also be used with a special structure of stainless steel butterfly valve, which can be use
Q : Foreign matter embedded in the sealing surface of the valve failure？
A : a. User reasons: the closed valve is fouled on the sealing surface; the medium is not clean and stuck on the sealing surface; the valve is not selected correctly, and the medium and its deposition are not considered comprehensively.
b. Solution: Open the valve with a slit to allow the high-speed liquid to flush off the dirt on the sealing surface; if the medium is not clean, the filter should be equipped with a filter drain device. The larger foreign object should be opened and the valve cover should be opened; the medium has hard particles. It is not advisable to use gate valves, such as plug valves and ball valves.
Q : The closing of the valve failure occurs (the dangerous leakage of the valve failure)？
A : a. Reason for manufacturing quality: The closing piece is not firmly connected to the valve stem.
b. User's reason: After the closing piece exceeds the top dead center or the card is stuck, continue to operate and break; the connector material is not selected correctly.
c. Solution: Correct operation, after the valve is fully opened, the handwheel should be slightly loosened to leave a gap; the corrosion and wear resistance of the medium should be considered.
Q : Leakage at the gasket of the valve failure？
A : a. Reasons for manufacturing quality: the gasket assembly does not meet the requirements; the static sealing surface is rough and uneven; the sealing pair is not clean, and foreign matter is added.
b. User reasons: the gasket is not selected correctly, does not meet the requirements of temperature resistance, pressure resistance, corrosion resistance; the operation is not stable, the temperature fluctuation is too large.
c. Solution: According to the working conditions, the gasket material and type should be selected correctly; it should be handled carefully.
Q : How can I protect against damage caused by valve leakage ?
A : Valve leakage will happen, but that doesn’t mean it needs to cause problems for your project. Here are three things you can do to protect against damage caused by valve leakage.
Specify the amount of leakage tolerance for the project. Leakage tolerance can vary widely from project to project. “Zero leakage” is not always necessary or desirable.
Select the appropriate valve size. Oversizing is one of the most common causes of valve leakage, particularly for control valves. Fortunately, it is also the most preventable through correct valve sizing and selection.
Perform regular testing and inspection. The best way to ensure that valve leakage doesn’t damage a system or cause undue harm to the environment is to perform regular valve testing and inspection. Early detection will allow you to fix minor problems before they become major ones.
Q : What’s the common causes of valve leakage ?
A : Valves can leak for a variety of reasons, including:
The valve is not fully closed (e.g., due to dirt, debris, or some other obstruction).
The valve is damaged. Damage to either the seat or the seal can cause leakage.
The valve is not designed to close 100%. Valves that are designed for precise control during throttling may not have excellent on/off capabilities.
The valve is the wrong size for the project.
Q : How many types of valve leakage ?
A ：There are two main types of valve leakage:Fugitive emissions leak from the valve into the atmosphere, posing potential environmental and safety hazards. More than half of a plant’s fugitive emissions are due to valves.
Leakage that remains in the piping system poses potential safety risks to the system itself.
Q : What is a ball valve?
A : A ball valve is an extremely durable stop valve that is designed primarily for On/Off function.
Q : What are gate valves?
A : Gate valves are most suited to services requiring full flow or no flow and infrequent operation.
Q : What is a check valve?
A : Check valves are mechanical valves that permit gases or liquids to flow in only one direction, preventing flow from reversing down the line.
Q : What are spring check valves?
A : Spring check valves have a disc held in place by a spring and ensure that gases or liquids flow in only one direction.
Q : What are swing check valves?
A : Swing check valves have a disc which swings into position to prevent back-flow while allowing full forward flow to be achieved through the valve.
Q : What are lift check valves?
A : Lift check valves work automatically with line pressure to prevent back-flow from occurring.
