1.0 Introduction Valves are mechanical devices that control the flow and gases in the process. They are essential components of piping system that conveys liquid, vapor and gases. They come in variety of material ranging from steel and plastic. There are different types of the valves such as globe, gate, ball, plug and check valve. Each of these valves has different features and functional capabilities. Some valves can self operated (automatically) while the other manually or with pneumatic or hydraulic

Mitral Valve Prolapse Mitral Valve Prolapse is a common heart valve abnormality and is the cause of mitral regurgitation. The flaps of the valve are “floppy” and don’t close tightly allowing the blood to flow backward in your heart. The affect is that blood can’t move through the heart or to the rest of your body as efficiently, making you feel tired and out of breath. History of Mitral Valve Prolapse The condition was first described by John Brereton Barlow in 1966, a world renowned South African

Transcatheter aortic valve replacement (TAVR) introduction to the clinical practice revolutionized the interventional cardiology ,it is a valuable option for a non –operable patient with sever aortic stenosis or high risk population however ,TAVR is associated with a risk of cerebral embolization and ischemic vascular events and possible neurological impairment the estimate of these complication is vary but it have been reported early and late after the procedure moreover the reported incidence
Every year, thousands people get heart valve replacements for various health reasons. There are multiple options for replacement valves that can generally be put into two categories, mechanical and biological. One of the mechanical options from the 1970s and 1980s was the Bjork-Shiley valve, which became infamous because of the controversy surrounding its stress fracture failures. These failures resulted the death of about 400 people, causing the value to be taken off the market. Using various ethical
Background Prosthetic heart valve replacement is performed in several hundred thousand patients per year worldwide and is recommended for many patients with severe valvular heart disease. Bioprosthetic heart valves and mechanical heart valves are the two major valve types. Mechanical valves are more durable than bioprosthetic valves but require lifelong anticoagulant therapy with vitamin K antagonists (warfarin) due to persistent risk of thrombosis and stroke. Warfarin has a narrow therapeutic window
6.1 Hazard and Risk Assessment A hazard is a potential damage, adverse health or harm that may effects something or someone at any conditions. Other than that, the risk may be high or low, that somebody could be harmed depending on the hazards. Risk assessment is a practice that helps to improve higher quality of the develop process and manufacturing process. It is also a step to examine the failure modes of the product in order to achieve higher standard of safety and product reliability. Unfortunately
moves down to a plunger then there is a check valve, below that is a spacer with the nozzle springs inside of it, lastly is the nozzle. All of these parts have specific and unique jobs. Nozzle has a needle in it that works kind of like a piston that once the pressure build up the needle forces forward and sprays fuel. There is a spacer above the nozzle with the nozzle springs that force the needle down. Above the spacer is a check valve, the check valve allows the right amount of fuel into the nozzle

during its journey through the heart, there are valves between each of the heart's pumping chambers. These valves are the tricuspid valve, the pulmonary valve, the mitral valve, and the aortic valve. The tricuspid valve is located between the right atrium and the right ventricle. The pulmonary valve is located between the right ventricle and the pulmonary artery. The mitral valve is located between the left atrium and the left ventricle. The aortic valve is located between the left ventricle and the
The specification of this valve is as follows: Valve type : 2 way normally closed Operating Pressure : 0 to 120 PSI Orifice : 2.5mm Coil : 12-24V DC 220V AC 1.6.3. Conveyer Belt: Conveyer belt is a carrying medium to carry the objects forward. A belt conveyor system consists pulleys with an endless loop of carrying medium that rotates about them. One or both of the pulleys are powered with battery to move the belt further. The pulley which is powered is called the drive pulley while

A wise man once told me “With any engine project, a solid foundation is necessary” (Jewett). Racing has been a major part of my life ever since I was little. While growing up, my uncles working on cars and racing together has impacted me. When I was little, I watched my uncles race, and it made me want to race when I got older. However, the instructions for rebuilding a twenty-three-hundred motor include the type, bottom end and the head. The fundamentals about rebuilding a twenty-three hundred
which the tricuspid valve is malformed and the valve itself is not in the correct anatomic place (Mayo Clinic Staff). This anomaly affects the right side of the heart – the tricuspid valve is located too deep into the ventricle, causing a smaller and weaker right ventricle. The space above the decreased right ventricle is made up of atrial tissue and this can be referred to as right ventricle dysplasia or an atrialized right ventricle (Reynolds). Typically the tricuspid valve has three freely moving
that may allow bacteria from the mouth to enter the bloodstream. Antibiotic premedication therapy is a prophylactic measure that prevents bacteria from being released into the blood stream. The bacteria can infect the heart lining, as well as the valves or blood vessels, causing them to become inflamed. Infective endocarditis (IE), the name for the inflammation, has the potential to be fatal or debilitating. The risk of developing IE can happen from a combi¬nation of high-risk patients and dental
Overview and Identification of Issues Valve Corporation uses a flat business structure, in which there are few to no levels of middle management. This is possible because of the highly trained workers, and small organization size at Valve. A flat business structure allows for the employees to be involved in the decision making process of the business, therefore raising their responsibilities. By having more responsibilities workers feel more involved and are more productive, compared to a normally
According to Abbott, “Mitral Regurgitation is the most common type of heart valve insufficiency in the United States.” The prefered treatment for mitral regurg is with open heart surgery to replace the insufficient valve. However for many patients, surgery is not an option due to their age, and underlying health conditions. Doctors started to look for a new way to help treat patients with mitral regurg. One that could be performed non invasively, without surgery. Thus the mitraclip was born! To
