  • Patent number: 10753506
    Abstract: A restricted access lockout system restricts access to remotely operated hydraulically actuated valves by utilizing a processor to compare each user's access code against a stored list. The user access code may be provided by card key with an embedded RFID chip, a designated application on a personal device such as a smart phone or smart pad that may communicate with the processor via Bluetooth, Wi-Fi, Internet, or radio. Once the processor grants access to operate various designated hydraulically actuated valves the designated hydraulically actuated valves are unlocked for designated period of time. After the designated period of time expires the hydraulically actuated valves are relocked. Generally, the lock is via a hydraulic cylinder where the hydraulic fluid may be isolated through one or more solenoid control valves. Hydraulic fluid within the hydraulic cylinder and the cylinder provide a sufficient counter to apply force so that the hydraulically actuated valves may not be manipulated.

  • Patent number: 9422783
    Abstract: An SPM valve for use in a subsea environment includes a spool selectively movable between first and second positions to thereby arrange the valve in respective armed and disarmed configurations. The particular arrangement of a supply port and discharge port with respect to the spool permits a pressurized working fluid supplied to the supply port to bias the spool to both the first and second positions once an external force is applied to the spool to initially set the spool in either the first or second position.

  • Patent number: 9173528
    Abstract: A shower unit includes a water delivery system having a main water line and a plurality of branches served by the main water line. Each branch terminates in one or more nozzles. A purge line selectively communicates compressed air into the main water line. Water is purged from the water delivery system by shutting off water flow into the main water line and introducing compressed air into the main water line through the purge line. Each of the branch valves is opened in sequence while keeping the remainder of the branch valves closed, allowing the compressed air to force any water in the respective branch out through the respective at least one output nozzle. The previously opened branch valve is then closed and the purging process is repeated for each successive branch.

    Abstract: The present invention relates to a method of controlling pressure maintenance equipment for a cooling and heating system. More particularly, the present invention relates to a method of operating and controlling, under optimum conditions, pressure maintenance equipment with multiple sensors so as to check for irregularities in the sensors which measure the same physical parameter. In the present invention, measurement values of two or more sensors are used to detect whether an abnormality has occurred in any sensor. If a sensor is determined to be abnormal, a measurement value of the abnormal sensor is excluded when determining a reference control value. Thereby, the pressure can be precisely and reliably controlled in response to actual conditions of the system.

  • Patent number: 8978690
    Abstract: An automatic condensate line purging device for HVAC condensation lines using pressurized gas. The purging device is installed in the condensate drain line of an air conditioning system allowing condensate flow through the device during normal operation where no clog has occurred in the condensate drain line. Should the drain line become clogged, a plug is displaced to seal the condensate drain causing the condensate to back-up up into the external condensate drain pan located beneath the condenser of conventional HVAC systems. When the drain pan fills with water, the safety float switch used to shut down the air conditioner is coupled to a solenoid valve mounted on the purging device wherein a charge of gas is directed into the drain line for removal of the clog.
