Water bag check valve

A valve system for drainage employed in sea water, oil tanks, petroleum derivatives and other refinery systems with low pressure reservoir, the system comprising:

• a check valve installed at a discharge of a flexible or hard filled reservoir surface containing a liquid, the check valve comprises:
• an upper flange joined to a foot;
• a ball bearing mounted on upper leg of the check valve with a teflon bushing placed in the bearing;
• a spring passed around a camshaft and below which a sealing washer, a sealing gasket, a seal washer and a lower special working bolt are stacked and mounted respectively;
• the camshaft is mounted onto the eyebolt and engage the camshaft with a bearing and a cam pin to engage a cam bearing;
• a lower flange gasket is inserted into the hard filled reservoir through holes being drilled onto the bottom of the flexible or hard filled reservoir;
• a drive rope or a release mechanism with one end being attached to the check valve through an eyebolt and the other end of the drive rope removed out of the flexible or hard filled reservoir;
• the drive rope is connected to an actuator and the liquid in the reservoir is displaced as the drive rope is tensioned, wherein
• the release mechanism has two stops which are activated at different times by employing the same command for both the movements;
• the camshaft has a specific path with two stopping points and in a single command opens and closes the check valve with a first command being a closed command and a second command being an open command;
• and
• the camshaft and the cam pin guiding the camshaft eliminates the tension of drive mechanism in the flexiable or hard filled reservoir.

• the drive rope is connected to an actuator and the liquid in the reservoir is displaced as the drive rope is tensioned, wherein
• opening and closing command of the flexible or hard filled reservoir or low pressure container is provided by a single channel with two different commands from a single point at different times;
• a flow prevention plug or a lower plug located at the discharge point of the hard filled reservoir is pulled off the hole by the actuator through the drive pulley to discharge the liquid out or forward the liquid freely to another pipe;
• and
• this cycle is repeated as many times as a practitioner wishes and concludes as desired.

A camshaft for a valve system comprises:

• a camshaft and a cam pin attached to the valve system for opening and closing of a valve;
• the camshaft is mounted onto an eyebolt which engage the camshaft with a bearing;
• the cam pin to engage a cam bearing, wherein
• the camshaft is specially machined and calculated to ensure that the valve is kept in different position each time when the drive rope is tensioned or stretched;
• and
• the cam pin placed on the cam bearing follows a path where each traction is followed by open, closed position of the traction in order respectively.
