Description
- This application is a Division-type Continuation of and claims priority to co-pending U.S. patent application Ser. No. 15/218,702, which claims priority to U.S. Provisional Patent Application No. 62/199,470 filed Jul. 31, 2015, both entitled Valve Replacement Device and having common inventor William Wilhite, which are incorporated by reference herein in their entirety as though fully set forth herein.
- Large tanks (e.g., oil, water, or other fluid) often have a valve to release fluid from the tank when desired. These valves may fail (e.g., begin to leak) and need to be replaced. Before replacing the valve, the entire tank has to be drained to avoid spilling or otherwise losing fluid during removal and replacement of the valve. This can be time consuming and expensive, for example, if a tanker truck has to be brought in to temporarily store the fluid drained from the tank.

FIGS. 8A-N illustrate example operation of the valve replacement device. - A valve replacement device and methods of operation are disclosed. In an example, the valve replacement device can be fitted through a valve that is to be replaced to stop flow of the fluid from the tank or other container. The existing valve may then be removed and replaced with another valve (or repaired and returned to service). The valve replacement device can then be removed to resume normal operation of the valve and tank.
- An example valve replacement device includes a body configured to thread onto a valve, and an insertion tube movable through the body. A seal is provided between the insertion tube and the body. The seal enables the insertion tube to be moved through the body while at least partially retaining a fluid within a portion of the body. A balloon is provided on the insertion tube. The balloon is configured to be inflated and deflated through the insertion tube. The balloon is inflated to retain a fluid within the tank while the existing valve is removed from the tank and replaced. The balloon is deflated and removed after replacement of the existing valve.
- An example method of valve replacement includes fastening a replacement body to a valve and opening a gate of the valve while the replacement body retains a fluid. An insertion tube is extended through the replacement body and through the valve to a position behind the gate of the valve. A balloon on the insertion tube is inflated in the position behind the gate of the valve. The balloon reduces or altogether prevents fluid from leaking out of a tank during valve removal. The replacement body can be removed and the valve can be removed.
- The valve can then be replaced. For example, the valve may be replaced with the same valve (e.g., a repaired or cleaned valve). Or the valve may be replaced with a different valve.
- Following replacement of the valve, the balloon may be deflated (e.g., via an air release on the insertion tube). The insertion tube and the balloon can be withdrawn from behind the gate of the valve so that the gate can be closed. The replacement body can then be removed from the valve.
- Before continuing, it is noted that as used herein, the terms “includes” and “including” mean, but is not limited to, “includes” or “including” and “includes at least” or “including at least.” The term “based on” means “based on” and “based at least in part on.”

FIG. 1 is a front perspective view of an examplevalve replacement device 10.FIG. 2 is a rear perspective view of the examplevalve replacement device 10 shown inFIG. 1 .FIG. 3 is a partial cutaway view of the examplevalve replacement device 10 corresponding toFIG. 1 .FIG. 4 is a partial cutaway view of the examplevalve replacement device 10 corresponding toFIG. 2 . - In an example, the
valve replacement device 10 includes areplacement body 12 having ahollow core 13 or cavity formed therein (see, e.g.,FIGS. 3 and 4 ). Thereplacement body 12 is shown having a substantially cylindrical shape, although other shapes are contemplated. Thereplacement body 12 is configured to fit onto a valve, such as a valve installed on a tank. The tank may contain fluid such as oil, water, milk, or any other fluid, or even a gas. Of course, thevalve replacement device 10 may be utilized for any valve replacement and is not limited to valves on tanks. Thereplacement body 12 may includethreads 14 to screw onto and off of the valve. However, other fitments (e.g., press-fit) may also be implemented. - The example
valve replacement device 10 also includes aninsertion tube 16. Theinsertion tube 16 is fitted through thebody 12 of thevalve replacement device 10, and can be moved, e.g., in the directions ofarrows insertion tube 16 includes avalve stem 20 with a valve. In an example, the valve is a Shrader valve, although any suitable valve may be implemented. Thevalve stem 20 enables air to be pumped through theinsertion tube 16 and into aballoon 22 on the opposite end, to inflate theballoon 22. The valve stem also enables air to be released from theballoon 22 to deflate theballoon 22. - On the other end, the
insertion tube 16 includes aballoon 22 that can be expanded and restricted in size (e.g., along the circular cross-sectional diameter). The balloon is configured to be inflated and deflated through the insertion tube. For example, theballoon 22 may be inflated by attaching an air pump or air compressor to thevalve stem 20. Likewise, theballoon 22 may be deflated by releasing the Shrader valve or otherwise opening the valve. Of course, theballoon 22 can be inflated with any substantial (gas or liquid) and is not limited to inflation by air. - During operation, the
balloon 22 is inflated to provide a blockage which retains a fluid (or gas) within the tank while the existing valve is removed from the tank and replaced. The balloon is then deflated and removed after replacement of the valve. - The example
valve replacement device 10 may also include aseal 24 between theinsertion tube 16 and thebody 12. Theseal 24 enables theinsertion tube 16 to be moved through thebody 12 while retaining a fluid at least partially within thebody 12. The seal may be fastened to the body by aseal flange 26 andfasteners 28. - The example
valve replacement device 10 may also include at least one (two are shown) release valve(s) 30 a-b on thebody 12. In an example, the valve(s) 30-a-b are petcock valves. The release valve(s) may be opened to relieve pressure build-up in thebody 12, e.g., by draining some or all of the fluid collected therein before removing thebody 12 from the valve during a valve replacement. - It is noted that the
valve replacement device 10 may be manufactured to any desired specifications, including size, shape, dimensions and material(s), as will be readily understood by those having ordinary skill in the art after becoming familiar with the teachings herein. -
FIG. 5 is an exploded parts side view of the examplevalve replacement device 10. In an example, thevalve replacement device 10 includes abody 12 configured to thread onto a valve, and aninsertion tube 16 that is movable through thebody 12. Aseal 24 is provided between theinsertion tube 16 and thebody 12. Theseal 24 enables the insertion tube 18 to be moved (e.g., slid back and forth) through thebody 12 while at least partially retaining a fluid within a portion of thebody 12. - The
valve replacement device 10 also includes aballoon 22 on theinsertion tube 16. Theballoon 22 may be connected to the insertion tube by a fitting 23. In an example, the fitting 23 is a barbed hose fitting. However, theballoon 22 may be connected to theinsertion rod 16 in any suitable manner. Theballoon 22 is configured to be inflated and deflated through theinsertion tube 16. Theballoon 22 is inflated to retain a fluid within the tank while the existing valve is removed from the tank and replaced. Theballoon 22 is deflated and removed after replacement of the existing valve. - The example
valve replacement device 10 also includes avalve stem 20 on an end of theinsertion tube 16. The valve stem 22 includes a valve that opens to permit air flow through the insertion tube and into the balloon to inflate the balloon. The valve in valve stem 20 closes to retain air within theballoon 22 and maintain theballoon 22 in an enlarged configuration. The valve in valve stem 20 may be opened to release air from theballoon 22 to deflate theballoon 22. - The example
valve replacement device 10 may also include at least one valve 30 a-b (e.g., petcock valves) on thebody 12. -
FIG. 6 is an assembled side view of the examplevalve replacement device 10.FIG. 7 is a partial cutaway side view of the examplevalve replacement device 10 corresponding toFIG. 6 . In bothFIGS. 6 and 7 , thevalve replacement device 10 is assembled onto avalve 1. In an example, thevalve replacement device 10 may be threaded onto mating threads on thevalve 1. Once thevalve replacement device 10 has been seated on the valve, the valve gate 2 (FIG. 7 ) can be opened and theinsertion rod 16 inserted through thevalve gate 2. It is noted that during this time when thevalve gate 2 is opened, some fluid may flow into the sealedchamber 13 of thebody 12 of thevalve replacement device 10. Theballoon 22 is then expanded at some point behind thevalve gate 2, as shown inFIG. 7 , to block fluid flow out of the tank (not shown inFIG. 6 or 7 ). The petcock valve(s) 30 a-b can be opened to drain some of all of the fluid from thechamber 13, e.g., into a collection basin. Thebody 12 can then be removed from the valve, and the valve replaced, as further illustrated byFIGS. 8A-N described below. - Before continuing, it should be noted that the examples described above are provided for purposes of illustration, and are not intended to be limiting. Other devices and/or device configurations may be utilized to carry out the operations described herein.
-
FIGS. 8A-N illustrate example operation of the valve replacement device. InFIGS. 8A and 8B , thereplacement body 12 is attached to a valve 1 (e.g., ontank 4 containing a fluid). InFIG. 8C , agate 2 of thevalve 1 is opened (e.g., by operatinghandle 3 on the valve 1). During this time, fluid from thetank 4 may flow intoreplacement body 12, but is retained within thecavity 13 of thereplacement body 12. - In
FIG. 8D , theinsertion tube 16 is extended (e.g., by pushing) through thereplacement body 12 and through thevalve 1 to a position behind thegate 2 of thevalve 1. InFIG. 8E , theballoon 22 is inflated in the position behind thegate 2 of thevalve 1. - In
FIGS. 8F and 8G , thebody 12 and thevalve 1 are shown being removed from thetank 4. InFIGS. 8F and 8G , thebody 12 body is shown removed from thevalve 1 first, and then thevalve 1 removed from thetank 4. In another example, however, thebody 12 and thevalve 1 may be removed from thetank 4 as a single unit, and then thebody 12 separately removed from thevalve 1. Theinsertion rod 16 andballoon 22 remains in place so that theballoon 22 slows or altogether stops fluid from flowing out of thetank 4. - In
FIG. 8H , the valve is shown being replaced with anothervalve 1′. Thereplacement valve 1′ may be valve 1 (e.g., after cleaning, inspection, or repair) reinstalled on thetank 4. Or thereplacement valve 1′ may be a different valve (e.g., a new valve). Thereplacement valve 1′ is shown installed on thetank 4 inFIG. 8I . InFIG. 8J , thereplacement body 12 is shown being installed onto thevalve 1′. Again, it is noted that while thereplacement valve 1′ andreplacement body 12 is shown inFIGS. 8H-8J being installed separately, in another example thereplacement body 12 and thereplacement valve 1′ may be connected together and then installed as a single unit onto thetank 4. - In
FIG. 8K , theballoon 22 is shown being deflated. In an example, the balloon is deflated by releasing the Shrader valve in valve stem 20 (e.g., by depressing the valve to release air in theinflation rod 16 and balloon 22). - In
FIG. 8L , theinsertion rod 16 is shown being withdrawn to a position in front of thegate 2′ of thevalve 1′. Thegate 2′ ofvalve 1′ is then closed, as shown inFIG. 8M , and thereplacement body 12 is detached (e.g., by undoing the thread) from thevalve 1′. Accordingly, thevalve 1 has been replaced byvalve 1′, while fluid was contained in thetank 4, without any or without substantial loss of fluid. - The operations shown and described herein are provided to illustrate example implementations. It is noted that the operations are not limited to the ordering shown. Still other operations may also be implemented.
- It is noted that the examples shown and described are provided for purposes of illustration and are not intended to be limiting. Still other examples are also contemplated.
