Definitions

  • This invention relates to a breaker valve, more particularly to a valve to be inserted in a fluid pressure line, whereby the valve is operative on a 5. reduction of pressure on the pressure side of the valve to disconnect to prevent flow in either direction.
  • a breaker valve which is included in the pressure line 25. and operative so ' that when the pressure reduces on the pressure line that the valve breaks and disconnects to thus completely isolate the equipment downstream of the breaker valve, there being then no connection between the two portions of the valve.
  • Fig. 1 is a cross-sectional view of the valve in the disconnected mode
  • Fig. 2 is a cross-sectional view of the valve connected for fluid flow.
  • valve 1 can include a main housing 2 having a hose coupling 3 for attachment of a hose 4 over a hose expander 5.
  • the hose expander 5 has an enlarged portion 6 defining a shoulder 7.
  • the valve 1 includes a connecting piece 8 which 10. may be connected to a chemical dispenser (not shown), the connecting piece including an internal seal 9 against which a non-return valve 10 biassed by a spring 11 seats.
  • the spring 11 bears at its outer end on the part of the body of the dispensing device to 15. which the connecting piece 8 is attached.
  • the connecting piece 8 is provided with a spigot 12 having a circumferential recess 13 into which catches 14 are adapted to engage to lock the connect ⁇ ing piece to the valve 1.
  • the catches 14 are position- 20. ed within slots 15 formed in the end of a central housing 17 retained by a circlip 16 bearing on flange
  • the catches 14 can slide radially between a position shown in Fig. 1 and that shown in Fig. 2, the
  • the thimble being cup shaped to engage the stem
  • a spring 23 is positioned between the interior of the
  • the stem 21 of the central housing 17 at its end 5. is provided with a plurality of radial slots 24 and the end abuts a wall 25 on the main housing 1.
  • a plunger 26 passes through the wall 25 and also the stem 21 of the central housing 17, the plunger 26 having a closed end 27 with a flange 28, O-ring 29 on
  • a seat 30 forming a cut-off valve.
  • the plunger is formed with a plurality of radial webs 31 extending from the closed end 27, and at its outer end is formed by a hollow cylindrical portion 32, the webs 31 join ⁇ ing to the cylindrical portion 32 such that fluid can
  • a spring 33 acts between a shoulder 7 of the hose expander 5 and the flange 28 on the plunger to cause the cut-off valve to close by the O-ring 29 sealing on the wall 25 about the plunger.
  • a pressure chamber 34 is provided between the wall 25 and the thimble 19, the slots 24 communicating fluid into the chamber.
  • a cup washer 35 seals the chamber and the cup washer 35 and the thimble 10 thus act as an annular piston.
  • a sealing ring 36 surrounds
  • tubular portion 32 is adapted to seal against the thimble wall 37 and the end of the connecting piece 8 when it is inserted into the housing.
  • GM y - WIP can flow from the hose 4, any pressure in the hose acting on the end of the plunger to thus assist in closing the cut-off valve.
  • the connecting piece 8 when no fluid pressure is 5. applied to the inlet, cannot be connected, for spring 23 moves thimble 19 to the catch release position as shown in Fig. 1, and hence the catches 14 will not engage in the recess 13 of the connecting piece 8.
  • the connecting piece when inserted engages the end of the 10. plunger 26 and moves the plunger to open the cut off valve by moving the O-ring 29 away from its seat, and when no supply of fluid is present the connecting piece cannot be locked in position.
  • the catches and recess are so designed that when the thimble passes the catch position, that the ejecting spring acting on the plunger will cause the connecting piece to be ejected completely from the body.
  • the cut-off valve in the body in this position is closed or if there is a reduced pressure on what is normally the pressure side of the system, that the cut-off valve is adapted to open and allow the air to enter into the system this air entering without taking
  • the unit is designed to be used only when it is particularly desirable and/or it is. required that the unit be used for the particular circumstances, and it will not be readily possible for unauthorized people such as child-
