• ### Flow Direction of Ball Valves

The flow direction of ball valves can be either bidirectional or unidirectional depending on its seat design and working conditions Conventional floating and trunnion mounted ball valves are usually bidirectional while some specific ball valves such as C ball valve, V port ball valve, orbit ball valve and cryogenic ball valve are unidirectional...

• ### Ball joint

In an automobile, ball joints are spherical bearings that connect the control arms to the steering knucklThey are used on virtually every automobile made and work similarly to the ball-and-socket design of the human hip joint A ball joint consists of a bearing stud and socket enclosed in a casing; all these parts are made of steelThe bearing stud is tapered and threaded, and fits into a ....

• ### Drag coefficient

For other objects, such as small particles, one can no longer consider that the drag coefficient is constant, but certainly is a function of Reynolds number At a low Reynolds number, the flow around the object does not transition to turbulent but remains laminar, even up to the point at which it separates from the surface of the object...

• ### What is the function of a steel ball?

Jun 28, 2009· Density = mass/volume let us say the mass of the steel ball and the ship are same but the steel ball is fully enclosed, a tight spherical volume, where as the ship is a hollow, occupies more ....

• ### Difference between Gate Valves and Ball Valves

Stainless Steel Ball Valves - (view products) Stainless steel is prized for its strength, and these ball valves are used in applications with high pressure and temperature It also won't rust or corrode, so it can be used in water and corrosive chemical applications Both ball and gate valves serve a purpose...

• ### ORBIT Valves Introduction

When an ORBIT valve begins to open, the core tilts away from the seat and line flow passes uniformly around the core face This eliminates the localized high velocity flow that typically creates uneven seat wear in ordinary ball, gate and plug valv The core then rotates to the full open position...

• ### Bearing (mechanical)

The first patent for a radial style ball bearing was awarded to Jules Suriray, a Parisian bicycle mechanic, on 3 August 1869The bearings were then fitted to the winning bicycle ridden by James Moore in the world's first bicycle road race, Paris-Rouen, in November 1869 In 1883, Friedrich Fischer, founder of FAG, developed an approach for milling and grinding balls of equal size and exact ....

• ### Oil Galley Steel Ball Removal
