Abstract
A stuffing box for a pressurized well where plural cables are attached end to end, and the connector has a larger diameter than either of the cables. The stuffing box structure is a combination that includes a housing for the connector and a packing gland for each of the cables. It has a latching holder that incorporates one of the glands, and a receptacle for holding the latching holder removably therein. The receptacle may be mounted at the well head, and it has the other packing gland removably attached to it. The latching holder has a seal that cooperates with the receptacle when the holder is inside. The whole arrangement permits retaining a pressure seal while moving the connector through the stuffing box in either direction.
Claims13
A stripping gland for maintaining a pressure seal with multicables having a larger diameter connector joining pairs of said cables, comprising in combination
- a packing gland for each of said cables,
- a housing for said connector;
- a latching holder for said housing,
- said holder incorporating one of said packing glands, and
- a receptacle for said latching holder having another of said packing glands associated therewith.
A stripping gland for maintaining a pressure seal with multicables having a larger diameter connector joining pairs of said cables, comprising in combination
- a packaging gland for each of said cables,
- a cylindrical housing for said connector,
- a latching holder for said housing,
- said holder incorporating one of said packing glands,
- a receptacle for receiving said latching holder therein and having another of said packing glands removably associated therewith, and
- means for mounting said receptacle for maintaining said seal at the exterior thereof,
- said latching holder comprising an O-ring seal on the exterior thereof for maintaining said seal with the interior of said receptacle when received therein, and
- means for releasably latching said housing in said latching holder,
- said releasable latching means comprises
- a pair of latching arms,
- means for pivoting said arms for movement into and out of latching position relative to said housing,
- means for biasing said arms into said latching position,
- first crank means on said arms for contacting said receptacle to pivot said arms against said bias to unlatch said housing, and
- second crank means on said arms for contacting said housing to pivot said arms with said bias to hold said housing in said holder when said holder and housing are out of said receptacle.
A stuffing box for use at a well head in a down hole survey wherein a plurality of cables are employed and at least two are joined at an end of each by a connector having an outside diameter greater than said cables, comprising in combination
- a housing for said connector to provide a predetermined size and to increase the tensile strength of said connector,
- a packing gland for each of said cables,
- a latching holder for said housing,
- said holder incorporating one of said packing glands,
- a receptacle for said latching holder and having another of said packing glands associated therewith, and
- means for mounting said receptacle at said well head to retain a difference of pressure between said well and the atmosphere outside.
A stuffing box for use at a well head in a down hole survey wherein a plurality of cables are employed and at least two are joined at an end of each by a connector having an outside diameter greater than said cables, comprising in combination
- a cylindrical housing for said connector to provide a predetermined size with square edges and to increase the tensile strength of said connector,
- a packing gland for each of said cables,
- a latching holder for said housing and incorporating one of said packing glands therein,
- a receptacle for said latching holder and having another of said packing glands detachably associated therewith, and
- means for mounting said receptacle at said well head to retain pressure in said well,
- said latching holder comprising
- an O-ring seal on the exterior of said holder for retaining said pressure at the interior of said receptacle when said holder is received therein,
- a pair of pivoted latching arms for releasably latching said housing,
- means for biasing said arms into latching position relative to said cylindrical housing,
- first means for pivoting said arms against said bias to unlatch said housing when said latching holder is in said receptacle, and
- second means for pivoting said arms with said bias to hold said housing latched into said holder when both are out of said receptacle.
