Improved Valve Means and a Method of Use Thereof
This invention relates to improved valve means and to a method of use thereof.
Although the following description refers almost exclusively to improved valve means for use in interface valve apparatus for a vacuum sewage system, it will be appreciated by persons skilled in the art that the improved valve means could be used in any apparatus in which an effective sealable valve is required.
It is known to provide vacuum sewage systems which rely on the formation of a vacuum within the sewage system to allow effluent discharged from a property to enter a vacuum sewer network. Interface valve apparatus is typically provided between each property or a group of properties and the vacuum sewer network. The interface valve apparatus is associated with a sewage or wet sump for the property or group of properties.
An example of conventional interface valve apparatus 2 is shown in Figures la and lb. Effluent 3 flows from a property or group of properties 4 into a wet sump 6 via pipe 8 under gravity, as shown by arrow 10. A pressure sensor pipe 12 is provided which has one open end 14 provided in the wet sump 6, and an opposite open end 16 connected to the interface valve apparatus 2. As the level of the effluent within the sump 6 rises, the pressure within sensor pipe 12 also rises, and this pressure increase is communicated to the valve apparatus 2. In particular, a controller sensor unit 16 is provided at the top of the interface valve apparatus 2 (but the controller unit could be provided anywhere on the valve apparatus as required) and, once the pressure on the pressure sensor pipe side of the controller 16 reaches a pre-determined level, a switch within the controller sensor unit 16 is actuated, thereby allowing a vacuum to be transferred to the main body 18 of the interface valve apparatus 2. This in turn allows a plunger valve 20 located in the main body 18 of the valve apparatus 2 to be moved from a closed position, as shown in figure 1, where effluent is prevented from entering the vacuum sewer network 22 from the wet sump 6 via effluent pipe 24, to an open position wherein the plunger valve 20 is moved to an open position with respect to pipe 24 and effluent in the wet sump 6 is allowed to flow from the sump 6 to enter the vacuum sewer network 22, as shown by arrow 26.
Once all, or a pre-determined volume, of the sewage has been removed from the wet sump 6 during an opening cycle of the interface valve apparatus 2, the plunger valve 20 remains open for a short period of time sufficient to allow atmospheric pressure to enter the vacuum sewer network. This air helps to break up the effluent and allows it to travel through the vacuum at relatively high speeds of up to 6 metres/second. Once the wet sump 6 is empty or has reached a predetermined effluent level, the pressure within the pressure sensor pipe 12 returns to normal atmospheric pressure and the plunger valve 20 closes to complete the cycle.
The controller sensor unit 16 comprises a main body 28, as shown in figure 2a, with a cover section 17, shown in figure 2e, which are assembled together in use by bolts 21 and nuts 23. The cover section 17 includes a pressure sensitive diaphragm 19 which sits just above a pressure sensitive valve, in the form of a flip flop valve 30, when the cover section and main body are assembled in use. The flip flop valve 30 is provided on the pressure sensor pipe 12 side of the controller sensor unit 16, as shown in figure 2a. It is to be noted that a flip flop valve 30 or similar valve arrangement could be used in other locations in the interface valve apparatus if required. When the pressure in the pressure sensor pipe 12 rises, this causes a positive pressure to be applied to the diaphragm 19, which in turn pushes on the flip flop valve 30 to cause the valve 30 to move from a closed position, wherein the valve 30 is seated over an aperture 32 provided through the main body 28 of the controller 16, to an open position, wherein the valve 30 is moved clear of aperture 32 (figure 2b shows the aperture 32 defined in the main body 28 of the controller unit with the valve 30 removed). With the valve 30 now open, this causes a vacuum provided in a compartment immediately below the main body 28 of the controller 16 to travel into a lower compartment within the apparatus, thereby causing a further valve diaphragm 34 to move, which allows the valve plunger 20 to be moved from the closed position to the open position. When the wet sump 6 has been emptied or has reached a pre-determined level of sewage, this removes the positive pressure applied to the pressure sensitive diaphragm, thereby closing the flip flop valve 30.
One example of a conventional flip flop valve 30 is made of metal and has a body portion 36, as shown in figure 2c. A convolute spring 38 is provided between a valve closure section 40 of the body portion and an attachment section 41 to allow the valve to be moved between the open and closed positions in use. A piece of rubber 42 is manually adhered to the valve closure section 40 at a location which normally sits over the aperture 32 when in a closed position to allow a seal to be formed between the valve closure section and the aperture 32 in use. The spring 38 resiliently biases the rubber and the valve closure section to a closed position in use. An attachment aperture 46 is provided at end 48 of the valve 30 for an attachment screw to be located therethrough in use for securing end 48 to the controller main body. This end attachment allows the flip flop valve to pivot upwardly and downwardly with respect to valve aperture 32 between the valve open and closed positions.
A problem with the conventional flip flop valve 30 is that the rubber seal 42 can fall off, thereby preventing an effective seal being formed over aperture 32. This prevents the entire interface valve apparatus 2 from working.
It is therefore an aim of the present invention to provide improved valve means which overcomes the abovementioned problem.
It is a further aim of the present invention to provide a method of using improved valve means which overcomes the abovementioned problem.
It is a yet further aim of the present invention to provide sewage interface valve apparatus that overcomes the abovementioned problem.

Referring firstly to figures 3a-3e, 4a-4c, there is illustrated improved valve means in the form of an improved flip flop valve 100 for use with vacuum interface valve apparatus according to an embodiment of the present invention. The vacuum interface valve apparatus can be a type described previously herein and which is supplied by redivac (ww.redivac.com), the details in their entirety of which are incorporated herein by reference. However, it is noted that the valve means of the present invention could be used in any suitable location on vacuum interface valve apparatus or could be used in any type of valve apparatus as required.
The flip flop valve 100 is similar in design to the conventional flip flop valve 30 described in figures 2c and 2d of this application. As such, the same reference numerals have been used to describe the same features as previously mentioned. The valve 100 works in the same manner as flip flop valve 30 with the exception that in place of the rubber seal 42, which in the conventional valve 30 is simply adhered to the valve closure section 40, attachment means in the form of an aperture 102 is defined in the valve closure section 40. The aperture 102 is for the positive engagement of sealing means in the form of a sealing pin 104 therewith in use.
The sealing pin 104 includes a sealing portion in the form of a head portion 106 having a sealing surface 108 for sealing engagement over aperture 32 of the controller main body 16 in use. Lower surface 110 which is opposite to sealing surface 108 has an engagement portion in the form of arm member 112 protruding outwardly therefrom. Engagement means in the form of a neck portion 114 is defined on the arm member 112 between the head portion 106 and a remaining portion of the arm member 112. The neck portion 114 has a smaller diameter to head portion 106 and arm member 112.
In order to fit the sealing pin 104 through aperture 102 on the valve closure section 40 of the valve 100, end 116 of arm member 112 is located through aperture 102 and is push fit in place with sufficient force such that the neck portion 114 sits in aperture 102. The larger diameters of the arm member 112 and the head portion 106 prevent the sealing pin 104 from becoming accidentally disengaged from the valve 100 in use.
Referring to figures 5, 6a-6b, there is illustrated a further embodiment of the present invention in which the sealing means is in the form of a sheet like or plate like seal 200. The seal 200 includes a sealing portion 202 having a flat or substantially flat sealing surface for sealing engagement over aperture 32 of the controller main body 16 in use. At opposite ends 204, 206 of the seal 200, engagement portions 208 are provided. Engagement means in the form of a recess 210 is provided in each engagement portion 208 at each end 204, 206 of the seal 200.
In order to fit the seal 200 to the valve closure section 40 of the valve 100, tab portions 212 are provided on opposite sides 214, 216 of the valve closure section 40 which protrude outwardly and inwardly from the valve closure section. The valve could be provided as a flat blank and arm portions protruding from the sides of the valve closure section can be folded to form the tab portions 212 in one example. The seal 200 is located on the valve closure section such that the tab portions 212 engage with the recesses 210 provided in the engagement portions of the seal 200. The engagement between the tab portions 212 and the recesses 210 on the seal 200 prevent the seal 200 from becoming accidentally disengaged from the valve 100 in use.
Figure 7 shows the valve 100 fitted to an upper surface 300 of controller unit 16 in use in one embodiment. The valve 100 is located such the sealing head portion 108 is able to sealingly engage over with and is directly opposite to aperture 32 on controller unit 16 when in a valve closure position in use. Screw 302 is used to secure the valve 100 to the upper surface 300 via attachment aperture 46 on the body portion 36 of the valve 100.
A stop plate, referred to as a top stop 304, is located over the valve closure section 40 of the valve 100 to further prevent dislodgement of the sealing pin 104 from the valve 100 in use. The stop plate includes an aperture 306 defined therethrough for the location of arm member 112 in use. Attachment apertures are located either side of the aperture 306 in the top stop 304 to allow attachment of screws 310 through the same to secure the top stop 304 and the valve 100 to the upper surface 300 of the controller unit 16.
