Abstract
A plumbing system test valve, includes a valve body defining a first pipe connection, a second pipe connection, and an access opening, a flow channel extends between the first pipe connection and the second pipe connection and a valve seat. A removable valve member is provided which is adapted to engage the valve seat of the valve body to prevent liquid from flowing along the flow channel between the first pipe connection and the second pipe connection. The removable valve member is removable through the access opening. At least one fill port is provided which is adapted to facilitate filling the valve body with liquid on one side of the valve member.
Description
TITLE OF THE INVENTION:
Plumbing System Test Valve FIELD OF THE INVENTION
The present invention relates to a valve used to test plumbing systems.
BACKGROUND OF THE INVENTION
When testing plumbing systems, plugs are inserted at one end of a plumbing line and the plumbing line is filled with liquid either upstream or downstream of the plug to test for leaks. These types of test plugs are well known in the art, examples of which can be found in the following patents: US 2,373,242 (Glashow 1945); US 3,154,106 (Ver Nooy 1964); US
3,442,295 (Ver Nooy 1969); US 4,040,450 (Boundy 1977); US 6,062,262 (Tash 2000); US

SUMMARY OF THE INVENTION
According to the present invention there is provided a plumbing system test valve, which includes a valve body defining a first pipe connection, a second pipe connection, and an access opening, a flow channel extends between the first pipe connection and the second pipe connection and a valve seat. A removable valve member is provided which is adapted to engage the valve seat of the valve body to prevent liquid from flowing along the flow channel between the first pipe connection and the second pipe connection. The removable valve member is removable through the access opening. At least one fill port is provided which is adapted to facilitate filling the valve body with liquid on one side of the valve member.
BRIEF DESCRIPTION OF THE DRAWINGS
These and other features of the invention will become more apparent from the following description in which reference is made to the appended drawings, the drawings are for the purpose of illustration only and are not intended to in any way limit the scope of the invention to the particular embodiment or embodiments shown, wherein:
FIG. 1 is a side elevation view, in section, of a first embodiment of plumbing system test valve constructed in accordance with the teachings of the present invention.
FIG. 2 is a side elevation view, in section, of a second embodiment of plumbing system test valve constructed in accordance with the teachings of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A first embodiment of plumbing system test valve, generally identified by reference numeral 10, will now be described with reference to FIG. 1. A second embodiment of plumbing system test valve, generally identified by reference numeral 100, will now be described with reference to FIG. 2.
Structure and Relationship of Parts of plumbing system test valve 10:
Referring to FIG. 1, plumbing system test valve 10 includes a valve body 12 defining a first pipe connection 14, a second pipe connection 16, an access opening 18, a flow channel 21 that extends between first pipe connection 14 and second pipe connection 16 and a valve seat 20. A removable valve member 22 is provided which is adapted to engage valve seat 20 of valve body 12 to prevent liquid from flowing along flow channel 21 between first pipe connection 14 and second pipe connection 16. Removable valve member 22 is removable through access opening 18. A first fill port 23 is provided which is adapted to facilitate filling valve body 12 with liquid on one side of valve member 22.
First fill port 23 is positioned on first side 24 of valve member 22. A
second fill port 26 is provided which is adapted to facilitate filling valve body 12 with liquid another side of valve member 22.
Second fill port 26 is positioned on a second side 28 of valve member 22. In this first embodiment, first fill port 23 and second fill port 26 are both sheltered within access opening 18. It will be understood that in some installations access opening 18 will be closed by a removable closure (not shown). It will be understood that in other installations, body 12 will be buried and access opening 18 will be accessible through a riser pipe extending to surface, with valve member 22 being inserted and removed at the end of a pole. It is envisaged that first fill port 23 and second fill port 26 will have removable plugs 30.
Operation of plumbing system test valve 10:
It will be understood that body 12 is incorporated into a plumbing installation. In order to test the plumbing system, valve member 22, is inserted through access opening 18 and engaged with valve seat 20. The positioning of valve member 22 prevents liquids from flowing through body 12 along flow channel 21. That portion of the plumbing system upstream of valve member 22 is, therefore, isolated from that portion of the plumbing system downstream of valve member 22. By selecting the appropriate fill port, first fill port 23 or second fill port 26, either the upstream portion of the plumbing system or the downstream portion of the plumbing system can be tested by connecting a water source and filling the system with liquid.
Structure and Relationship of Parts of plumbing system test valve 100:
Referring to FIG. 2, plumbing system test valve 100 is similar in most respects to plumbing system test valve 10. Identical reference numerals will, therefore, be used to identify identical components. However, plumbing system test valve 100 has a fundamental difference, that being the positioning of the fill ports. The purpose of illustrating this embodiment is to make clear that the fill ports do not have to be sheltered within the access opening. Plumbing system test valve 100 includes a valve body 12 defining a first pipe connection 14, a second pipe connection 16, an access opening 18, a flow channel 21 that extends between first pipe connection 14 and second pipe connection 16 and a valve seat 20.
A removable valve member 22 is provided which is adapted to engage valve seat 20 of valve body 12 to prevent liquid from flowing along flow channel 21 between first pipe connection 14 and second pipe connection 16. Removable valve member 22 is removable through access opening 18. A first fill port 123 is provided which is adapted to facilitate filling valve body 12 with liquid on one side of valve member 22. First fill port 123 is positioned on first side 24 of valve member 22. A second fill port 126 is provided which is adapted to facilitate filling valve body 12 with liquid another side of valve member 22. Second fill port 126 is positioned on a second side 28 of valve member 22. In this second embodiment, first fill port 123 and second fill port 126 are both positioned on valve body 12 on opposed sides of access opening 18. It will be understood that in some installations access opening 18 will be closed by a removable closure (not shown). It will be understood that in other installations, body 12 will be buried and access opening 18 will be accessible through a riser pipe extending to surface, with valve member 22 being inserted and removed at the end of a pole. It is envisaged that first fill port 123 and second fill port 126 will have removable plugs 30.
