Description
COMBINED BASE UNIT AND CONTROL VALVE FOR M: UNDERGROUND WATER SUPPLY CHAMBER This invention relates to a base unit for an underground water supply chamber in which the base unit incorporates an integral control valve. GB 2 148 997A discloses a stopcock chamber assembly having a plastics base which is adapted to receive a stopcock and bold it in an upright position to prevent the stopcock twisting about the axis of the pipework to which it is connected.This arrangement is one of a number of attempts to overcome the problems encountered in the water supply industry in which twisting of stopcocks when torque is applied to them ca:- result in damage to the associated pipework. It has also been found difficult to conduct maintenance work on such assemblies because removal and replacement of the supporting base unit beneath the stopcock is-both awkward and time consuming.
The present invention seeks to alleviate such prD5'e..s by the provision of a relatively inexpensive base unit which incorporates an integral control valve for a water supply chamber.
To this end, one aspect of fhe invention provides a base unit for an underground water supply chamber which comprises a moulded plastics body having a through bore providing an inlet passageway, an outlet passageway and a control valve therebetween to control the flow of fluid through the passageways of the base unit, the control valve being adapted for operation remote fro the base unit.
According to a feature of this aspect of the invention, the control valve may comprise a fluid control portion accor:irnodated within a valve seat provided by the through bore intermediate the inlet and outlet passageway and a valve ste extending from the fluid control portion perpendicularly with respect to the through bore to terminate in a stem pprtion adapted to cooperate with detachable valve actuating means. In constructions where this feature is adopted, the fluid control portion may comprise a substantially Spherical notable ball having an opening therethrough, said ball being rotatable with respect to the valve seat by rotation of the valve stem so that the opening is positioned to allow open or close communication between the inlet and outlet passageways.
Preferably, the valve seat is formed by an enlarged portion of the through bore and includes opposed partspherical sidewalls and a part-spherical base.
It is also preferred to form the ball and the stem integral, the stem extending through the base unit so that the terminal portion stands proud of an upper surface of the base unit.
According to another feature of this aspect of the invention, sealing means may be provided between the ball and each of the inlet and outlet passageways and between the stem and adjacent parts of the base unit.
According to yet another feature of this aspect of the invention, the end of each of the inlet and outlet passageways may be provided with connector-means by which the base unit can be connected to water supply pipework.
Preferably, the base unit includes an integral upstanding cylindrical wall by which the base unit can cooperate with a guard tube of a water supply chamber.
It is still further preferred that the control valve is moulded in situ with the base unit. However, a removable control valve may be provided in the base unit.
Another aspect of the invention provides a water supply chamber for underground installation incorporating a base unit-according to any of the eight immediately preceding paragraphs.
A base unit for an underground water supply chamber embodying the invention will now be described, by way of example, with reference to the accompanying drawings, in which:
FIGURE 1 is a schematic view of a water supply chamber incorporating a base unit according to the invention;
FIGURE 2 is a part-sectional view through a base unit according to the invention; and
FIGURE 3 is a section along the line A-A in Figure 2.
Referring first to Figures 2 and 3 of the drawings, a base unit 10 of substantially cylindrical configuration is moulded to form a suitable plastics material and is formed with an integral through bore 12. The through bore provides an inlet passageway 14, an outlet passageway 16 and a control valve seat cavity 18 intermediate the inlet and outlet passageways to receive a valve for controlling the flow of fluid between the inlet and outlet passageway.
The valve seat cavity 18 is provided by an enlarged central portion of the through bore 12 and comprises diametrically opposed part spherical side walls 20 and 22, respectively and a part spherical base 24. A stepped valve stem receiving bore 26 extends through the base unit from the top wall lOa thereof perpendicularly with respect to the through bore and communicates with the valve seat cavity 18.
A control valve 28 formed from nylon or other suitable plastics material includes a hollow spherical ball 30 received in the valve seat cavity 18 and an integral valve stem 32 received in the valve stem receiving bore 26.
Preferably, the control valve is moulded in situ with the base unit so as to be rotatable with respect thereto but it is envisaged that the valve may be removably inserted in the base e.g. by providing a detachable base portion around the stem as shown in broken lines in Figure 2. Thec spherical ball is formed with a central bore 34 which upon rotation of the valve can be aligned coaxially with the inlet and outlet passageways as shown in Figure 3 to allow flow of fluid through the base unit or rotated through 90 degrees therefrom to shut off the flow of fluid between the inlet and outlet passageway to the position as shown in Figure 2.In order to ensure adequate sealing of the ball within its valve seat, a pair of 'O'-ring seals 36 and 38 are inserted in annular cavities 40 and 42, respectively, to abut the ball in the inlet and outlet passageways.
The valve stem has an enlarged diameter portion 32a adjacent the ball which is accommodated within a correspondingly enlarged diameter portion of the receiving bore and a reduced diameter portion 32b which is received within a correspondingly reduced diameter portion of the receiving portion and which terminates above the top surface 10a of the base unit.
A further 'O'-ring seal 44 is inserted in an annular cavity 46 formed in the stepped down part of the valve stem receiving bore to ensure adequate sealing between the valve stem and the bore 26. The exposed portion 32c of the valve stem is formed with a flange 48 which abuts the top surface 10a of the base unit and is adapted to receive one end of a valve actuator key 50 by which the valve can be operated remote from the base unit.
Figure 1 schematically shows the base unit 1O incorporated in an underground water supply chamber 52. Inlet and outlet pipes 54 and 56 are connected to the base unit by suitable connecting means. In this regard, screw threaded connectors 58 and 60 may be provided at each of the radially outermost ends of the inlet and outlet passageways. However, other suitable connecting means may be utilized, preferably formed integrally with the base unit.
The remainder of the water supply chamber 52 includes a telescopic guard tube comprising axially adjustable inner and outer sleeves 62 and 64 respectively. In order to support the guard table, the base unit is formed with an integral upstanding cylindrical wall 66 into which the lower end of the inner sleeve 62 is fitted. The outer sleeve 64 is formed with an upper flange 68 remote from the base unit to which an access cover 70 at ground level is fitted. Other forms of guard tubes known in the art may be employed. Preferably, the space between the top surface of the base unit and the upper end of the actuator key is filled with-a heat insulating material stash as expanded polystyrene granules 'G' to provide protection against the effects of cold weather and to prevent the build-up of dirt within the chamber.
