supporting gas environment

Providing minimization of liquid phase leaks through the valve seal with the use of capillary compression

Aim. Substantiation of the optimum pressure value of the supporting gas medium, which will ensure the minimum leakage of the liquid medium through the joint of the valve seal. Method. As the research object the Electric hydro-pneumatic two-way valve (EHTV) has been chosen. The force factors caused by the action of the sub-valve pressure, the super-valve pressure and the force of the drive spring are determined.
