10 & 6 Series Tooling
Triton ACS - Accumulator Charging System

The Triton ACS - Accumulator Charging Systems is compromised of  dedicated tooling for installation (Torque Tool)  and charging (Charging Head). Torque and Charging operations have been purposely separated to provide enhanced HSE features only available with the Triton ACS system.   

Both tools rely on internal hex head jacking bolts that thread into the top of the Triton ACV and lock the tool and valve together. The length of the bolts in the tools provide timing for torque and charging operations.

Triton Torque Tool (for Installation and Removal)

Installation of the Torque Tool onto a Triton ACV is accomplished by turning the internal jacking bolt with a 3/8" hex head wrench.  The Triton Torque Tool has 3 torque pins that engage the 3 "scallop" grooves on the Triton ACV flange and allow torque to be applied. Once the Torque Tool is fully installed and the torque pins are engaged, the hex head wrench is removed.     A 1/2" square drive is then inserted into the top of the torque tool for installation and removal torque.  Once the valve installation or removal is complete, the 1/2" square drive is removed and a hex head is then used to disengage the jacking bolt from the Triton ACV.  

The Torque Tool has no ability to charge but it can be used to dump pressure. The Torque Tool has an HSE                        feature to prevent unscrewing under pressure.  Prior to torque pin engagement the jacking bolt timing cracks the sealing mechanism open.   If gas pressure is present it will flow out the valve and into the Torque Tool and exit through 6 audible warning ports. 

 

To unscrew a valve under pressure a  technician would have to ignore the gas escaping and the loud  audible noise (97dB at 3,000 psi), continuing screwing in the jacking bolt until the valve is wide open and torque pin are sufficiently engaged, remove the hex head wrench, and insert a 1/2" square drive into the top of the tool to unscrew the valve containing pressure.  Audible Warning Video is on the "10 & 6 Series Videos" page of this website.

Charging Tool  (For Gas Charging)

The Triton Charging Tool is unique and is required to direct incoming gas pressure through the side port on a Triton ACV.  The Triton Charging tool adapts to and provides a threaded connection for common charging kits already being used on rigs.   As an HSE feature the Charging Tool does not have torque pins so it has no ability to  apply unscrewing torque to a Triton ACV.     

 

The primary duties of the Charging head is to direct incoming charging pressure between the upper and lower seal into the side port of the ACV and to provide operation of the valve for charging and dumping.   The Charging Tool contains an internal Jacking bolt that  "pulls" the Triton ACV into the matching inner profile that contains an upper and lower square oring that seals on the outer body of the valve.   This is a tight fit that is easily accomplished with bolt force

 

For charging operations the Jacking bolt must be  turned to a full stop prior to the application of charging pressure.   A full stop opens the valve and blocks it open mechanically.   If charging pressure is applied to a valve not blocked open mechanically by the jacking bolt then the bias piston in the ACV will cause the valve to shut immediately blocking gas pressure from entering the bottle.   No amount of gas force can open the valve as it only tries to close harder as the gas pressure increases.   If the Charging head receives pressure prior to the valve being opened mechanically then the pressure needs to be isolated and bled off in the charging head BEFORE the jacking bolt is turned to open the valve and block it open.  Damage to the soft seal can occur if valve is opened with charging pressure.   The soft seal is designed to assist bottle pressure sealing and is not designed to hold back charging pressure.   The soft seal can withstand full bottle pressure dumps of 9500 psi with no damage.
