Abstract

A wall unit tap connector with protective devices has a body with an internally threaded outlet 12 for a standard type bib tap 14 or hose, a mounting backplate 16 a valve body 10 in which is incorporated one or more non-return valve flanged sub-unit assemblies 20 which can be removed or replaced and a threaded inlet 29 for a supply pipe. Test plugs (e.g 26, Figs 2,4 not shown) may be provided. <IMAGE>

Description

WALL UNIT TAP CONNECTORS WITH PROTECTIVE DEVICES Taps with or without hosepipe couplings for gardening, garage or general purposes are invariably connected to a mains water supply system and secured to wall facings, posts or any rigid structure that will withstand the various pressures and stresses that occur when hosepipes are connected to taps.

Water Authorities now require that all fittings discharging from any system connected to the public mains must have one or more protective devices at the point of discharge to prevent contamination of water in the mains. In order that the protective devices cannot be removed from the supply system it is necessary to install the device or devices as near to the discharge point as possible where it cannot be tampered with. When non-return valves are used as the protective device it is necessary in some cases to use test plugs in order to check the efficacy of the nonreturn valve.

According to the present invention there is provided an assembled unit comprising a valve body with an internally threaded outlet into which can be secured a standard type tap with or without a hose connector, a backplate with apertures through which fasteners can secure the assembled unit to a post or wall facing, a valve body or bodies with or without test plugs into which are incorporated one or more replaceable non-return valve flanged sub-units and a threaded inlet connector which can be varied to suit supply pipes made from different materials.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which: Figure 1. shows a cross section of the assembled wall unit with a non-return valve and separate hose union tap.

Figure 2. shows a cross section of an assembled wall unit with a non-return valve and a test plug.

Figure 3. shows in perspective an assembled wall unit with a non-return valve body and test plug, a threaded male inlet and a threaded female outlet.

Figure 4. shows an assembly of a wall unit with two in-line non-return valve units and test plugs.

Referring to the drawing Figure 1, the wall unit tap connector comprises a body 10 with a threaded female outlet 12 into which can be secured a standard hose union or ordinary bib tap 14. The body 10 has a wall plate 16 with two or more apertures 17 through which wall fasteners (not shown) secure the body te a wall, post or rigid structure. Within the valve body 10 and secured by a threaded connection 19 between the upper part of the valve body 10 and the lower section lOa is a non-return valve sub-unit assembly 20 secured by flanges which can be replaced by unscrewing the threaded connection 19. A threaded inlet 21 of the body 10 can be varied to suit various diameters of different pipes. In Figure 2 the upper part of the body 10 and the valve sub-unit assembly are identical to those parts described in Figure 1 but the lower part of the bodi now becomes part 22 with a preformed tee stud 24 having a shouldered recess 25, a threaded aperture 26 and a threaded test plug 27. An inlet connector 28 is secured by means of threads to the body 22 and a threaded inlet 29 can be varied to suit the diameters or connectors of different types of supply pipes. In certain installations Water Authorities require in-line double non-return valves each with a test plug and this is shown in Figure 4 which shows the upper part of the valve body 10 together with the non-return sub-unit assembly 22 and test plug 27 as shown in Figure 2 extended by removing inlet connector 28 and adding a second unit identical to that shown in Figure 2 with items numbered 19a to 29a

Claims

CLAIMS 1. A wall unit top connector with protective devices comprising a valve body with an internally threaded outlet into which can be secured a standard type tap with or without a hose connector, a backplate with apertures through which fasteners can secure the assembl-ed unit to a post or wall facing, a valve body or bodies with or without test plugs into which are incorporated one or more replaceable non-return valves flanged sub-unit assemblies and a threaded inlet connector for a supply pipe.
2. A wall unit tap connector with protective devices as claimed in Claim 1 wherein a non-return valve flanged sub-unit assembly is incorporated within a valve body having a threaded inlet connector.
3. A wall unit tap connector with protective device-s as claimed in Claim 1 or Claim 2, wherein a non-return valve flanged sub-unit assembly is incorporated in a valve body having a test plug and a threaded inlet connector.
4. A wall unit tap connector with protective devices as claimed in any preceding Claim wherein one or more non-return valve flanged sub-unit assemblies are incorporated in a valve bod with one or more test plugs, the bo-dy having a threaded inlet connector.
5. A wall unit tap connector with protective devices as claimed in any preceding Claim wherein the non-return valve flanged sub-unit assemblies can b-e removed and replaced.
6. A wall unit tap connector with protective devices substantially as described herein with references to Figures 1 to 4 of the accompanying drawings.
