ES Series Ball Joint

ES Series Ball Joint
ISUTAMI ball joint installed between the ball head and connecting rod body to realize the driving connection and transmission effect of the ball head and connecting rod body. The driving force of the ball head part can drive the rod part to move through the connecting rod.Constitute an important part of the connector parts, metal rod, the ball head casing to long axis of the ball head ball head, ball head through the front of the ball head with the ball head casing hinge axle hole edge, ball head between seat and steering shaft set at the inner hole surface groove ball head, can reduce the ball head wear, improve the tensile characteristics of the spindle.

ES Series Ball Joint Features

Ball joint widely used in mechanical industry, commonly referred to as self-reliance type differential pressure control, its function is to control the drive in a branch or a differential pressure, make basic constant, pressure difference and its consumption is changing, it is through adjusting its opening, the differential pressure to adjust their consumption, in order to realize the controlled object is constant.This kind of differential pressure control valve has been widely used in heating and air conditioning engineering, especially in engineering, so it is familiar and understood by everyone.Its role is to control its own differential pressure, so can be called its own differential pressure control valve.At the same time, its application in hvac engineering is discussed.The working principle of structure and work itself difference control.The spring, the pressure film and the rod are consolidated together, and the outlet force is transferred into the sealing chamber of the upper part of the pressure sensing through the pressure guide pipe, and the lower part of the pressure sensing is the inlet force.The precontraction of the spring is determined according to the set value, even if the elastic force is equal to the pressure acting force under the set pressure difference condition.And according to the stroke is far less than the principle of pre-contraction.So that's the equilibrium at any open degree.Different degrees of opening, the equilibrium state is not equal.Obviously, as the opening increases, the equilibrium state increases.However, by selecting, it is completely possible to control the deviation of the equilibrium state relative to within a certain range within the full stroke.

The work of self - differential control in the system can be divided into two cases, the current state is closed.If the back and forth difference is less than the setting difference, it will continue to close. In this case, it is a shutdown.And when it reaches equilibrium, it goes up almost to zero.Until the close, there is less than the case, no longer has the ability to pressure difference.In short, the opening degree can be automatically adjusted in the open state when the pressure difference of the self is controlled, and the difference before and after is basically constant.
