Definitions

  • This invention relates to a valve arrangement for filling a pressure vessel with hydraulic fluid under pressure and for controlling the outflow of fluid from the vessel to limit the internal pressure of the vessel, it may find use in numerous hydraulic or pneumatic devices but would typically be used in low-cost hydraulic preload devices for use in preloading mine hanging supports.
  • the invention additionally extends to a mine support preload device including the valve arrangement of the invention.
  • preloading devices have been developed for elongated timber mine props which provide immediate "active" support. Hydraulically inflated preload devices are now commonly used for this purpose and are typically vessels with thin steel walls having non-return valves through which water is pumped at high pressure into the devices. The devices are deformed by the water and transfer preloading forces to the timber props.
  • the above preload devices may be equipped with pressure relief valves which allow the devices to release water in a controlled manner such that the devices act as yielding elements in support systems.
  • the above action provides the preload devices with the ability to maintain a constant resistance to the loads imposed on them, in use, and to yield controllably if the applied load increases above a preset load.
  • These pressure relief valves are typically mounted externally on the preload devices where they are exposed to and are susceptible to mechanical damage in the confined work space in mine workings such as stopes. In cases of severe damage, the inlet and or relief valves could and frequently do permit the pressure water to be exhausted from the pressure vessels of the preload devices to render the load supports on which they are located ineffective and so to compromise the hanging support in the mine work area.
  • a valve arrangement for filling a pressure vessel with hydraulic fluid under pressure and for relieving fluid under pressure from the vessel at a predetermined pressure above the filling pressure includes; a one-way filler valve and a one-way pressure relief valve which are carried by a common valve arrangement body which is located wholly within the pressure vessel, in use, and a hydraulic fluid inlet adaptor which is fixed, in use, to the outer wall of the vessel with a single fluid passage extending, in use, between a fluid inlet to the adaptor and the inlet into the valve arrangement body for delivering hydraulic fluid under pressure to the filler valve and through which hydraulic fluid is vented from the pressure relief valve at or above the predetermined fluid pressure in the pressure vessel.
  • the valve arrangement body may house only the pressure relief valve and, in use, may be movable relatively to the inner wall of the pressure vessel and includes an outwardly projecting formation which carries a terminal portion of the fluid passage from the inlet adaptor to the valve arrangement body, movable means which is attached to the inner wall of the pressure vessel, in use, for movably holding the valve body over the inlet fluid passage from the inlet adaptor with the fluid passage portion through its outwardly projecting formation in register with the remainder of the fluid passage to provide the one-way inlet valve which is opened by lifting the valve arrangement body from the inlet passage by water under pressure to permit fluid flow into the pressure vessel through the space between lifted projecting formation and the inner surface of the pressure vessel wall with the fluid pressure in the vessel closing the projecting formation on the valve arrangement body onto the inner wall when fluid filling of the vessel is terminated.
  • the valve body holding means may be a leaf spring which is secured at a first end to the valve arrangement body with its second end, in use, being attached to the inner wall of the pressure vessel at a position remote from the valve body to bias the outwardly projecting formation onto the inner surface of the pressure vessel wall over the fluid inlet passage.
  • the outwardly projecting formation on the valve arrangement body preferably carries a resilient seal which projects from and surrounds the portion of the fluid passage through it and which when the projecting formation is biased by the spring and hydraulic fluid under pressure in the pressure vessel into pressure contact with the inner wall surface of the pressure vessel surrounding the fluid passage, in use, seals the fluid passage against hydraulic fluid leakage from the pressure vessel through the fluid passage.
  • the filler valve and the pressure relief valve may be located in a back-to-back relationship in the valve arrangement body with the fluid passage inlet to the fluid body being situated between the valve members of the inlet and pressure relief valves in the body.
  • the hydraulic fluid inlet adaptor carries on its free end on the outside of the pressure vessel a hose connector formation.
  • the inlet to the pressure relief valve may include a filter for filtering particulate material from hydraulic fluid in the pressure vessel as the fluid passes through the filter to the pressure relief valve.
  • a preload device for location on or in a load support for preloading the support between the hanging and foot walls in a mine working includes a sheet metal pressure vessel which is expandable in the direction of the load to be imposed on the support, and the valve arrangement of any one of the above claims through which hydraulic fluid is pumped, in use, under pressure into the pressure vessel to expand the load support into high pressure contact between the foot and hanging wall in the mine working and through which hydraulic fluid is relieved from the pressure vessel on the load acting on the support causing the fluid pressure in the pressure vessel to exceed the predetermined pressure.
  • the load support is preferably an elongated timber load support prop with the preload device located at one end of the prop.
  • Figure 1 is a sectioned side elevation of a preload device valve arrangement shown attached to the preload device's inner wall by a leaf spring, and
  • Figure 2 is a sectioned side elevation of a valve arrangement of the invention shown rigidly attached to the wall of the vessel.
  • FIG. 1 The invention is described in two embodiments with reference to Figures 1 and 2.
  • the two embodiments have a number of common features.
  • Each contains a combination pressure relief valve 10 and non-return filler valve 11 which may be mounted in various manners on or in a common valve arrangement body 12 within a fluid pressure vessel 13 which is shown only fragmentally in the drawings.
  • the pressure relief valves 10 typically make use of a plunger 14 which is biased against an orifice 16 by a spring 18 or similar elastic element.
  • the orifice forms part of a water passage 20 which extends between the inside of the vessel to the outside of the vessel through an inlet adaptor 22 which carries on its free end a hose connector formation 24.
  • the plunger 14 or orifice 16 may be fitted with an elastomeric seal 26 to ensure that fluid does not leak through the orifice in the valve's closed state.
  • the valve 10 opens to allow water to pass out of the vessel through the water passage 20 when the force generated by the pressure of the water acting on the area of the plunger exposed by the orifice exceeds the biasing force of the spring 18.
  • the spring force may be adjustable by means of a setting screw 28 which is shown in the Figure 1 embodiment or it may be set by controlling the geometry of the mechanism. These have the effect of allowing control of the predetermined pressure at which the valve 10 opens. Once the internal pressure has dropped as a result of water outflow, the force equilibrium of the internal pressure in the vessel 13 and spring 18 is again reached and the valve 10 reverts to its closed state and so limits the internal pressure of the vessel.
  • valve arrangement body 12 is movable relatively to the inner wall of the pressure vessel 13 and includes an outwardly projecting formation 32 which carries a portion of the water passage 20 into the valve body 12 and a resilient elastomeric seal 34.
  • the seal is fixed to the outer surface of the formation 32 around the water passage portion in it and, when raised from the position shown in the drawing, projects below the under surface of the formation 32.
  • valve body 12 is fixed to one end of a leaf spring 36 the other end of which is tack welded to the inner surface 38 of the pressure vessel 13 to bias the valve arrangement body 12 towards and the seal 34 against the inner surface 38 of the pressure vessel over the water passage 20 outlet from the inlet adaptor 22.
  • a connector from a high pressure water hose is connected to the hose connector 24 on the inlet adaptor 22 and the hose is opened.
  • High pressure water enters the passage 20 and lifts the valve arrangement body 12 upwardly against the bias of the spring 36 for the seal 34 to be separated from the inner surface 38 of the pressure vessel 13.
  • the inlet pressure water now fills the pressure vessel, through the gap between the seal 34 and the vessel surface 38, to the inlet water pressure. With there now being no pressure differential across the valve arrangement body nor the spring 36 the bias of the spring closes the seal 34 onto the vessel surface 38 to shut the inlet valve.
  • valve arrangement body houses the one-way pressure relief and inlet valves 10 and 11 which are arranged in a back-to-back relationship to each other in the body 12 as shown in the drawing.
  • valve arrangement body 12 is fixed to the inlet adaptor 22 in the pressure vessel.
  • the inlet valve 11 of this valve arrangement is a simple spring biased check valve which is opened by the pressure of inlet water which enters the body 12 between the two valves.
  • the pressure relief valve 10 operates as described above.
  • a filter element may be present in all embodiments to prevent impurities in the fluid in the pressure vessel 13 from interfering with the operation of the pressure relief valve 10.
  • This invention extends also to a mine support preload device which includes the above pressure vessel 13 and the valve arrangement of the invention.
  • the mine support is an elongated timber mine prop and the preload device is any one, as mentioned in the preamble to this specification, of a number of commonly used devices which are adapted in one way or another to be engageable with one of the prop ends.
  • the mine support could be a support pack and the preload device could be a mat-type pressure vessel which is composed of two substantially flat superimposed peripherally sealed metal sheets, one of which could have at one of its ends which, in use, is not in contact with the pack material, a pocket which is pressed outwardly from the sheet for housing the valve arrangement of the invention.
  • the timber prop preload device would typically be inflated with water to a pressure of 12Mpa. In service the preload device would generally be set to relieve at approximately 14Mpa. This pressure may vary considerably depending on specific user requirements.
  • valve arrangement of this invention with a mine support preload device over the valve or valves currently used on the preload devices of the prior art is that the valve arrangements are fully shielded by the pressure vessel wall from impact damage. Even in cases of severe impact with mine machinery or the like only the inlet adaptors 22 could be damaged, and in the worst cases, be totally removed from the pressure vessels which carry them. In this serious event the Figure 2 embodiment of the valve arrangement may be sufficiently damaged to release water from the pressure vessel because of the direct connection of its inlet adaptor with the valve arrangement body 12. The Figure 1 embodiment does not, however, have this direct connection and will therefore be capable of withstanding even more serious damage without failure.
