Abstract
A liquid flow control device including a hand operable flow control member (3) includes means (8, 9) for facilitating hand rotation of the member (3), and in addition a region (7) adapted for operational engagement by a spanner or the like so that additional turning force can be applied to the member (3) when the user is not able to rotate the member by use of fingers and thumb. In a modification, the region (7) is provided with a bore to receive a tommy bar. <IMAGE>
Description
SPECIFICATION
Flow control apparatus
This invention relates to flow control apparatus, and more particularly to flow control apparatus including a main body and a manually operable member which when in a first operational setting blocks a fluid flow path through the main body to the flow of fluid and when in a second operational setting effectively opens the flow path to the flow offluid.
A particularform of control apparatus is constituted by a barrel tapping valve for insertion in the tapping opening of a cask, barrel orthe likefor alcoholic drinks such as wines and/or beers. In these control valves the main body thereof has a portion intended to be driven into the outlet port of the cask or barrel, a connector part or parts for connection to piping our ducking leading to a liquid dispensing location orto a simple discharge pipe. The fluid path from the main body to each of these latter parts is provided with a manually operable control member.
Such control valves are conventionally provided with oppositely directed ears or lugs which enable the user of the control valve to turn the control member between the open and closed settings. The length and overall size of such lugs or ears is, in practice, often limited. Thus, for example, in the case of a control valve having two manually operable control members the transverse width of the ears is set bythe need forthe operable members to be rotatable without one fouling the other during the rotation thereof.
In the event that the operable member becomes difficult to move orfixed in a particular operational position by reason of the material flowing therethrough leaving a tacky or sticky residue or the like whereby the operable member becomes difficult to rotate it is a usual practice to produce the requisite displacement and or dislodgement by hitting the ears with a hammer or other solid device. Since it now an intention in the brewery trades that the control valves should be formed from plastics material the hitting of plastics ears could easily result in irreparable damage to the control valves.
Broadly, according to a first aspect ofthe invention there is provided a liquid flow control device comprising a hand operable valve flow control member including meansforfacilitating hand rotation ofthe member, wherein the rotatable member is provided with a region adapted for operational engagement by a torque exerting means for producing an operational force which is a substitutefororaforceforaugmenting anyturning effort exerted by hand on the operable member.
Preferably the portion ofthe rotatable member having the ears or lugs is shaped in such manners to be able operationally to receive a conventional spanner or similar tool.
Conveniently, the portion for engagement by the tool has a hexagonal or square cross-section or has a section defining tool receiving flats orsurfaces.
For a better understanding ofthe invention and to show how the same may br carried into effect referencewill now be madeto the accompanying drawing in which:
Figure lisa part sectional elevation of a manually operable flow control operating member.
Figure2 is a further elevation of the member of
Figure 1,this further elevation being in part section; Figure 3 is a top elevation of the member of Figures 1 and 2; and Figure4is an underside elevation of Figure 1.
Referring to the drawing the member 1 incorporates a main body2which istapered in accordance with the requirements of British
Standard Specification for a shut-off part of a fluid flow control valve. A diablo shaped fluid flow through bore 3 is provided in the main body. Thus the bore 3 has two oppositely directed frusto-conical sections 4,5. The upper part 6 ofthe main body merges into a neck portion 7 which is provided with a pair oftransversely directed lugs or ears 8,9.
The neck portion 7 is made hollow so thatwhen the article is formed by moulding a plastics material, cooling contraction of the neck portion does not lead to splitting or the like of the neck portion. In addition, the hollow formation leads to a higher resistance to the effects oftorsional forces and bending forces.
The neck portion has a hexagonal outer cross sectional surface 10 and an inner hexagonal cross sectional surface 11.
In practice, the neck portion 7 is dimensioned so that it is an operational fit size for receiving a standard size a spanner orthe like.
A bolt 12 is integally moulded into the lower part 13 ofthe body portion. This bolt 12 is intended to receive a standard nutorthe like (not shown) which is to act by way of a washer orthe like (not shown) to holdtheoperablememberwithin atapmain body such as has been disclosed in ourcopending application No8512003fi1ed 11th. May1985.
In practice,thewasherformation can be similarto that used inthearrangementofthecopending patent application.
To facilite the positional locating of the washer (notshown)the lower end 13 ofthe main body has a portion 14 of a rectangular cross-section forfitting into a correspondingly shaped internal bore to the washer.
Whilst the ears of the Figures have been shown at the uppermost end of the neck portion it will be appreciated that the ears could be located at other positions lengthwise of the neck portion.
Aiso the cross section of the outer surface ofthe neck could be other than hexagoal. For example, the neck portion could have a square cross section or any other section providing spaced apart flats for receiving a spanner like tool.
Furthermore, it will be appreciated that the positions of the ears or lugs 8,9 in relation to the faces of the shape ofthe neck portion 7 can be varied.
In one such arrangement the ears 8,9 effectiveiy project from the join between two adjacent faces.
In a variation of the control valve the neck portion can be apertured to receive a tommy or like bar by means of which the control valve can be actuated.
Claims (6)
1. A liquid flow control device comprising a hand operable valve flow control member including means forfacilitating hand rotation of the member, wherein the rotatable member is provided with a region adapted for operational engagement by a torque exerting means for producing an operational force which is a substitute for or a force for augmenting anyturning effort exerted by hand on the operable member.
2. A liquid flow control device as claimed in claim 1, wherein the rotatable member incorporates oppositely directed ears or lugs intended to be engaged by a user'sthumb andfinger,the lugs or ears extending transversely of the axis of rotation of the rotatable member, and wherein a region of said memberadjacenttothe lugs or ears is adapted operationally to receive the torque exerting means.
3. A liquid flow control device as claimed in claim 1, wherein the rotatable member has a region shaped in such mannerastobeableoperatonallyto receive the torque exerting means, and wherein oppositely directed ears or lugs extend from said region in a direction transversely ofthe axis of rotation of the rotatable member.
