For the load borne by the ball socket, the working pressure mainly acts on the seat sealing ball, so that the shear force generated by the seat sealing ball on the ball socket core is analyzed by finite element method according to the pressure of 5000PSI, in which the pressure acting surface is the part of the seat sealing ball outside the ball socket core (blue part in the figure). After adding the load, as shown in Figure 2.14, the red arrow indicates the pressure.
