Definitions

  • control of liquid flow along a conduit depending on a downstream condition is a well known activity.
  • a downstream condition such as a liquid level or pressure
  • control is achieved via a swivellably mounted member as automatically mechanically controlled without the application of addition power while the extent of force available in causing the member to be swivelled to a conduit opening condition is constrained by other factors the unobstructed release of the member from its conduit closing condition is of particular importance. It is also sometimes desirable to make use of as large as possible liquid flow ability along a conduit even though the flow there along must be controlled.
  • This invention relates to a liquid flow regulator installable to regulate the flow of liquid from an upstream supply according to a downstream demand.
  • the invention finds useful application in the case of serving as a float valve type liquid flow control regulator as thus fitted with buoyancy means.
  • Liquid flow controllers for automatically mechanically controlling the flow of liquid along a conduit depending on a downstream condition such as a liquid level or pressure is commonly known in the art.
  • a downstream condition such as a liquid level or pressure
  • a disadvantage of the equipment know to the applicant is that even at maximum flowrate it cannot extensively use the cross sectional diameter of a conduit resulting in a slow response even in the case where quick and extensive flow is required.
  • butterfly valves While in line swivellably mounted equipment such butterfly valves are also commonly used for controlling the flow of liquid along a conduit they are commonly operated with the use of substantial addition power such as being hand operated, thus not performing a continuous controlling function, or operated via an external powering means such as an electric motor in which case the equipment can be used to perform a liquid flow control function.
  • an external powering means such as an electric motor in which case the equipment can be used to perform a liquid flow control function.
  • the involvement of the external powering means is particularly important to ensure that the valve does not remain stuck in its conduit closing condition despite being
  • Figure 1 shows in diagrammatic sectioned side elevation a liquid flow regulator, according to the invention, in the form of a float valve type regulator in its upstream supply sealing off condition,
  • FIG. 2 shows in diagrammatic detail the fitting of the flow control member of the regulator to its conduit
  • Figure 3 shows the regulator in full end view the direction of arrow A in figure 1 ,
  • Figure 4 shows the regulator in the same direction as figure 3 though in the flow conduit fully open condition
  • Figure 5 diagrammatically shows the operation of the regulator when used for controlling a liquid level
  • Figure 6 diagrammatically shows the operation of a further embodiment of the regulator as fitted with a delaying mechanism for delaying its reaction to an alteration of a liquid level.
  • a liquid flow regulator in the form of a float valve type regulator is generally indicated by reference numeral 10.
  • the regulator 10 comprises a flow control member in the form of a swivellably mounted flow control disk 12 that is fitted via a horizontal shaft 14 secured the frontal face 12J of the disk 12, to a tubular conduit 16 of circular end profile to perform a butterfly valve type operation about a horizontal axis 18, and a mechanically operable flow control member manipulating facility in the form of a liquid level responsive manipulating facility that is provided by an arm arrangement 20 incorporating one or more arms 22 fitted at its position remote from where secured to the disk 12 with a buoyancy member 24.
  • a liquid flow path 26 is thus defined along the conduit 16 along which the flow of a liquid such as water is controlled once the regulator 10, as operatively installed, is in use.
  • the disk 12 is formed to sealably seat against the inner wall of the conduit 16 while still at a forward slanted angle with respect to the transverse plane through the conduit 16 once closing off the latter, as clearly shown in figures 1 and 2.
  • the conduit 16 is of circular profile the disk 12 is thus of matching oval profile to achieve its sealable seating at the appropriate angle of forward slanting 25.
  • the disk 12 can typically lie at an angle of forward slanting 25 of in the order of 20 degrees once it sealably seats against the conduit 16. Sealing between the disk 12 and the inner wall of the conduit 16 can be achieved by way of any conventional technique.
  • the peripheral rim 12.2 of the disk 12 can be formed with a circumferential groove 28 into which a sealing ring 30 is fitted once the regulator 10 is ready for use.
  • the inner wall of the conduit 16 can be suitably lined.
  • the peripheral rim of the disk 12 can be fitted with permanent sealing substance or the disk 12 can be in the form of opposite rigid planar members between which a resilient leaf is sandwiched to the extent of forming a peripheral sealing strip.
  • Constraining of the disk 12 to so lie in the direction liquid flow along the conduit 16 is achieved by a position along the inner end of the arm arrangement 20 coming to rest on the frontal lip 16.2 of the conduit 16 when the disk 12 fully open, as again shown in figures 5(b), 6(a) and 6(b).
  • the arm arrangement 20 is secured at its inner end to the upper section 12.3 of the disk 12.
  • the inner end of the arm arrangement 20 extends slightly offset to the transverse direction relative to the frontal face 12.1 of the disk 12. Swivelling of the disk 12 from its flow path closing off condition thus has the effect of the upper section 12.3 of the arm 12 moving towards the discharge end 16.1 of the conduit 16 on opening of the regulator 10.
  • the regulator 10 naturally makes provision for its conventional installation to a liquid supply line at the upstream side of the conduit 16.
  • the arrangement 20 consists of one rectilinearly extending rigid arm 22 as thus secured at its inner end to the upper section 12.3 of the disk 12.
  • the free end of the arm 22 carries the buoyancy member 24.
  • the arm 22 is shown to extend rectilinearly it will be appreciated that it must be formed to accommodate the location of installation of the regulator 10. if thus submerged when installed the arm 22 will have to be appropriately formed to ensure that the buoyancy member 24 still effectively performs its function. It can thus be formed with one or more locations of discontinuity along its length or even extend arcuately.
  • the operation of the rigid arm embodiment of the regulator 10 simply involves the opening or closure of the flow path 26 along the conduit 16 once the regulator 10, as operatively installed, is in use in response to the movement of the buoyancy member 24.
  • the disk 12 When the level of liquid in conjunction with which the buoyancy member 24 is used is at a desired upper elevation, the disk 12 is positioned in its conduit sealing condition, as shown in figure 5(a). Dropping of the level results in the descent of the buoyancy member 24 causing the progressive opening of the flow path 26 in response to forward swivelling of the disk 12.
  • the elbow 34 as dividing the arrangement 20 in two arms 22.1 and 22.2, enables the buoyancy carrying arm 22.1 to swivel relative to the trailing arm 22.2 along an arc 42 5 between an upper stop 38 formed by a stop block 36 fitted to the arm 22.2 and a lower stop achieved by the facing ends of the arms 22J , 22.2 being formed to come to abut against one another once they extend in general rectilinear alignment with respect to one another.
  • the effect of the delaying mechanism is to cause the disk 12 to maintain a specific extent of opening despite a rise in liquid level. o When the buoyancy member 24 is thus at its fully dropped condition, as shown in figure 6(a) the disk 12 is in its fully opened condition.
  • a rise in the liquid level causes the arm 22.1 to commence swivelling about the arc 42 in response to a rise in the elevation of the buoyancy member 24 while the arm 22.2 retains its downward pending condition as so gravitationally promoted by the weight of this arm and the forward tilting of
  • a further advantage of the invention is that the regulator 10 need not be designed to substantially make provision to overcome an upstream supply pressure when the flow of liquid such as water must be diminished and eventually terminated in response to a rising level. Owing to being mounted to swivel about a central axis 18 the upstream supply 30 pressure effectively exerts a balancing force about the axis 18 on the face 12.4 of the disk 12 thus neither urging it to swivel the one or the other way.
  • the force required to be exerted by the buoyancy member 24 for swivelling the disk 12 into its flow path closing condition must thus only be of adequate magnitude to achieve such swivelling action.
  • On opening the arrangement 20 need only be of adequate weight to gravitationally cause the forward swivelling of the disk 12 about its axis 18.
  • the arm 22 or arms 22.1 , 22.2 need not be lengthy.
