Abstract: A product delivery system includes a product transport vehicle having at least a plurality of tank compartments, internal valves, control valves, fluid property sensors, temperature sensors, overfill sensors, pressure sensors, a system controller, and a memory module. The product delivery system may be operable to communicatively connect with the loading system at a loading station, a fleet management system, or a cloud system to obtain information, such as the amount of liquid product to be loaded into a tank compartment. The product delivery system may be operable to compare the volumes of the tank compartments with the amounts of liquid product to be loaded at a loading station and maintain the internal valve or control valve in a locked state or transition the internal valve or control valve to an unlocked state based on the comparison. Other comparisons based on liquid type or distribution tank volume can also be made.

Abstract: A hopper tee for redirecting the flow of material from one passage to another passage includes a radius providing a transition between the passages. A port at the exterior of the radius includes an upwardly-open cavity having a bottom wall disposed within the radius and forming a sacrificial wall extending between the bottom wall and the inner surface of the radius. The cavity provides an indication that material moving through the tee has worn the wall of the radius by the creation of a passage between the interior of the tee and the cavity and expelling material through the passage to the exterior of the tee. A plug may be secured within the cavity allowing a user to continue to use the tee until the tee is rotated or replaced. The radius may include a thickened wall for providing added structural support and sacrificial material.

Abstract: A pneumatic lock assembly for securing a valve comprises a lock pin engaging a contact surface on a poppet assembly. The head of a poppet creates a sealing relationship with an end of the valve. A guide with a bore extends between the exterior and interior of the valve terminating at a sleeve. The sleeve slidably receives a stem extending from the poppet head. A spring biases a pin, slidably received within the pylon bore, into engagement with a contact surface on the valve stem for securing the valve head in a closed position. The pin may be pneumatically disengaged from the groove by forcing air from a pneumatic power source into a bore in the pin. A cap assembly at the exterior of the valve provides protection for the lock assembly and allows for manual disengagement of the pin from the groove.

Abstract: A valve assembly for sealing a port of a housing includes a primary sealing member and a secondary sealing member mounted to a valve body. Valve body includes a lower body with an upper portion depending from the body having a cross sectional diameter less than the upper body, and a lower portion depending from the upper portion having a cross sectional diameter less than the upper portion. The primary member includes apertures and is slidably mounted to the upper portion, and the secondary member is mounted to the lower portion. In a closed position the secondary member seals against the primary member, and the primary member seals against the port. Downward movement of the valve body unseals the secondary member from the primary member allowing venting through the apertures, and then unseals the primary sealing member from the port allowing full venting through the housing.

Abstract: An overfill probe is utilized in each compartment of a multi-compartment transport tanker and has a depending sensing tube for detecting liquid overfill conditions. An overfill detector is within the bottom end of the probe tube and is thus protected from damage. Internal damage to the probe and malfunction of the system also precluded by connecting the exposed cap of the probe to the detector by a longitudinally extensible, stretchable cable extending through the tube to the detector, or a circuit board may be retained within the depending tube. Additionally, a thermistor socket and an optic socket are provided which are part of the overfill protection system, each having contact connections that may be readily replaced when worn without removing or replacing the wiring within the socket assembly.
