Latest Patents
Hrinsin's latest patents include the Wedgeball valve and the Railway tank car cradle support. The Wedgeball valve features a unique design where at least one ball valve segment is located within a partial valve cage mounted within a tank. This design includes an inclined sealing surface that the ball valve segment engages in a closed position. The operating shaft is inclined with respect to the outlet chamber, and the rotation of the shaft drives the valve segment between open and closed positions. This innovative design minimizes flow restriction and enhances the efficiency of the valve.
The Railway tank car cradle support patent describes a tank car stub sill support structure that utilizes a half ring attached to the inner end of a stub center sill at each end of the car. This structure is designed to effectively manage coupler impact loads, transmitting them into the upper cover plate and tank shell in shear. This method prevents distortion and deformation of the tank shell, making it more resistant to buckling.
