Abstract

The isolation valve assembly includes a ball member stabilized relative to a ceramic ring, an upper ball housing and a lower ball seat with a set of shifting bars, a set of locking bars, and a set of supporting bars. The shifting bars rotate the ball member between opened and closed configurations, while the locking bars and supporting bars stabilize the ball member. The supporting bars are off set from the shifting bars and locking bars, and the supporting bars are anchored to the assembly separate from the locking bars and shifting bars. The actuation of the shifting bars is independent from the locking bars and the supporting bars so that the ball member can be held in the opened or closed configuration with more stability.

First claim

We claim:

1 . An isolation valve assembly, comprising:
a lower housing having a first lower housing end and a second lower housing end; a transition sleeve having a first transition sleeve end and a second transition sleeve end, said second transition sleeve end extending out of said second lower housing end; a bottom housing having a first bottom housing end and a second bottom housing end, said first bottom housing end engaging said second lower housing end of said lower housing, said transition sleeve extending into said bottom housing from said first bottom housing end and extending through said second lower housing end, a connector sleeve having a first connector sleeve end and a second connector sleeve end and being positioned within said bottom housing, said first connector sleeve end engaging said transition sleeve, said second transition sleeve end being fixedly inserted into said first connector sleeve end, wherein longitudinal movement of said connector sleeve corresponds to longitudinal movement of said transition sleeve; an upper ball housing having a first upper ball housing end and a second upper ball housing end and being within said bottom housing, said first upper ball housing end engaging said second connector sleeve end, said first upper ball housing end being inserted into said second connector sleeve end; a ceramic ring having a first ceramic ring end and a second ceramic ring end, said first ceramic ring end engaging said second upper ball housing end; a ball member comprising:
a ball body having a through hole;
a first axis member on a first lateral side of said ball member;
a second axis member on a second lateral side of said ball member, said first axis member being aligned with said second axis member,
wherein said ball member rotatably engaged to said first axis member and said second axis member, said first axis being cooperative with the said second axis member, wherein a first ball member position corresponds to a closed configuration with said ball member in a sealed relationship to said ceramic ring, said ball body engaging said second ceramic ring end, and wherein a second ball member position corresponds to an opened configuration with said ball member in fluid connection with said ceramic ring, said through hole being aligned with said ceramic ring
a first shifting pin fixed on said first lateral side of said ball member, said ball member actuating between said first ball member position and said second ball member according to position of said first shifting pin to said first axis member; and
a second shifting pin fixed on said second lateral side of said ball member, said second shifting pin being cooperative with said first shifting pin, said ball member actuating between said first ball member position and said second ball member according to position of said second shifting pin to said second axis member,
wherein said ball member is actuatable between said first ball member position and said second ball member cooperative with said first shifting pin; a lower ball seat having a first lower ball seat end and a second lower ball seat end, said first lower ball set end engaging said ball member, said lower ball seat being comprised of a locking shoulder, wherein said first ball member position corresponds to said closed configuration with said ball member in a sealed relationship to said lower ball seat, said first lower ball seat end in sealing engagement to said ball member, wherein said second ball member position corresponds to said opened configuration with said ball member in fluid connection with said lower ball seat, said first lower ball seat end in fluid connection with said ball member; a first shifting bar being comprised of a first shifting bar anchor end and a first shifting bar slide end, said first shifting bar engaging said first shifting pin so as to actuate said ball member between said first ball member position and said second ball member position according to position of said first shifting bar, wherein said first shifting bar anchor end fixedly attaches to said connector sleeve, and wherein said first shifting bar slide end removably engages said lower ball seat according to said position of said first shift bar and said ball member between said first ball member position and said second ball member position; a second shifting bar being comprised of a second shifting bar anchor end and a second shifting bar slide end, said second shifting bar engaging said second shifting pin so as to actuate said ball member between said first ball member position and said second ball member position according to position of said second shifting bar, said second shifting bar being cooperative with said first shifting bar, wherein said second shifting bar anchor end fixedly attaches to said connector sleeve on an opposite side of said connector sleeve from said first shifting bar, and wherein said second shifting bar slide end removably engages said lower ball seat according to said position of said second shift bar and said ball member between said first ball member position and said second ball member position; a first locking bar having an upper first locking bar end and a lower first locking bar end and being comprised of a first engagement means to said first axis member, wherein said upper first locking bar end fixedly attaches to said upper ball housing, and wherein said lower first locking bar end fixedly attaches to said lower ball seat; a second locking bar having an upper second locking bar end and a lower second locking bar end, said second locking bar being cooperative with said first locking bar and being comprised of a second engagement means to said second axis member, wherein said upper second locking bar end fixedly attaches to said upper ball housing, and wherein said lower second locking bar end fixedly attaches to said lower ball seat; a first supporting bar having an upper first supporting bar end and a lower first supporting bar end, wherein said upper first supporting bar end fixedly attaches to said lower housing, and wherein said lower first supporting bar end being fixedly attaches to said upper ball housing; and a second supporting bar having an upper second supporting bar end and a lower second supporting bar end, said second supporting bar being cooperative with said first supporting bar, wherein said upper second supporting bar end fixedly attaches to said lower housing, wherein said lower second supporting bar end being fixedly attaches to said upper ball housing, and wherein said first shifting bar and said second shifting bar are offset from said first supporting bar and said second supporting bar.

2 . The isolation tool assembly, according to claim 1 , wherein said first shifting bar anchor end attaches to said connector sleeve at said bottom connector sleeve end.

3 . The isolation tool assembly, according to claim 2 , wherein said first shifting bar anchor end has a T-shape, said bottom connector sleeve having a complementary cavity to fixedly engage said T-shape of aid first shifting bar anchor end.

4 . The isolation tool assembly, according to claim 1 , wherein said second shifting bar anchor end attaches to said connector sleeve at said bottom connector sleeve end.

5 . The isolation tool assembly, according to claim 4 , wherein said second shifting bar anchor end has a T-shape, said bottom connector sleeve having a complementary cavity to fixedly engage said T-shape of aid second shifting bar anchor end.

6 . The isolation tool assembly, according to claim 1 , wherein said upper first supporting bar end fixedly attaches to said second lower housing end of said lower housing, and wherein said lower first supporting bar end fixedly attaches to said second upper
