Definitions

  • the present invention relates to the charging or discharging of compressed fluid cylinders.
  • Approved containers for the storage and distribution of toxic chemicals such as chlorine fall into two broad categories based on capacity:
  • the first group is bulk shipping containers, tanker trucks, rail cars barges and large stationary vessels;
  • the second group consists of two groups of containers which may be transportable to a specific application site. These are in general "cylinders” in the 50-150 pound range and “ton" containers containing as the name implies or the order of 2000 pounds of materials.
  • a factor in the present design is that in some cases, an actuator or chlorination unit may already be in place on a cylinder. Additionally, in other cases some elements such as a vacuum regulator, a flow meter or an ejector may be in place. In these circumstances only a fraction of an inch clearance may be available to engage the valve stem, typically 3/4 inch. The present invention has been made with these problems in mind and provides for engagement ofthe valve stem with only 3/4 inch clearance.
  • the present invention also provides for an onboard leak detector, which will close the valve in the case of a leak.
  • Many systems employs vacuum system which is intended to cause air to enter the system instead ofthe gas leaking to the atmosphere, but not all leaks in all places will be controlled by this system and the leak detection system may still serve a valuable function, even in connection with a vacuum system.
  • the present invention also has the advantage of minimizing the possible leaks in change over in that the "new" cylinder need not be opened until the time of its actual use or some limited stand-by period as may be desired in any particular circumstances.
  • the present invention overcomes several ofthe problems and disadvantages ofthe prior art as described above by making it possible to carry the actuator and its console on the cylinder.
  • FIG. 1 illustrates a cross-sectional view of a prior art 150 pound cylinder for chlorine or sulfur dioxide and for ammonia.
  • FIG. 2 illustrates a cross-sectional view of a prior art chlorine and/or sulfur dioxide "Ton" container.
  • FIG.3 illustrates a cross-sectional view of a prior art chlorine container valve.
  • FIG. 4 illustrates a top view ofthe control console ofthe present invention.
  • FIG. 5 illustrates a side view of the "ton cylinder" embodiment ofthe present invention.
  • FIG. 6 illustrates a top view of the "ton cylinder" embodiment of the present invention.
  • FIG.7 illustrates the present invention mounted on top of a cylinder in accordance with the teachings ofthe present invention.
  • FIG. 8 illustrates a side view ofthe present invention.
  • FIG. 9 is a block diagrammatic representation of a preferred embodiment ofthe present invention.
  • the present invention overcomes the deficiencies ofthe prior art and achieves its various advantages and objectives by providing for the mounting ofthe actuator and its control console on or in very close physical proximity to the cylinder to be filled or discharged.
  • the system includes an electric motor that rotates the cylinder valve system toward open or closed position without interfering with or requiring additional adapters for the filing or discharge hardware.
  • the motor, gears, and controls are assembled as one unit to eliminate the necessity for a separate control panel or interconnecting control wires.
  • the system has the capabilities for integral leak detection with automatic shutdown, battery backup in the event of power failure, remote control by leak detector, remote control panic button, remote low weight transmitter, remote vacuum switch for automatic switch-over systems. And other remote digital signals.
  • the system requires only a flexible power cord for trickle charge ofthe battery backup, which makes the assembly totally portable when not in use. Placement of the system container can be accomplished by connection to the cylinder valve, a permanent stand, or a movable stand on casters. Motor and controls are accomplished through an on-board microprocessor with integral LED displays for "CLOSED,” “ALIGN,” and “OPEN” indicators. Programming is accomplished through an integral keypad. Actual valve position is transmitted to the microprocessor from a direct-coupled potentiometer.
  • the larger size cylinders to which the present invention may be applied are shown in the typical "Ton" container of FIG. 2 which might be used for chlorine or sulfur dioxide.
  • the "Ton" container 6 is placed in a horizontal position with the upper valve 8 and the lower valve 10 in a vertical line, one above the other, with the upper valve 8 on top.
  • the valves 8 and 10 may be protected by a protective hood 12.
  • the present invention relates to the field of valve actuation and to systems for use with pressurized fluid containers. Under certain prescribed or predetermined conditions, it is often desirable to be able to shut-off automatically a fluid flow control valve that is normally actuated manually.
  • the present invention also provides for an onboard leak detector, which will close the valve in the event of a leak.
  • Many systems employ a vacuum system which is intended to cause air to enter the system instead ofthe gas leaking to the atmosphere. Though not all leaks in all places will be controlled by this system, the leak detection system may still serve a valuable function even in connection with a vacuum system.
  • a LED display 102 is provided with program buttons 104 Close switch 106, align switch 108, open switch 110 and associated indicator lights are provided, as well as a failure indicator light.
  • the console 100 is provided with a handle 114 and has a valve stem receptacle 116.
  • FIG. 9 shows, in the form of a block diagram, the cooperation of several ofthe elements ofthe present invention.
  • the cylinder (containing the fluid to be ejected) 602 has a valve stem 608 which is operatively engaged by the automatic actuator and its console 604.
  • Other components ofthe actuator system may be included within the console 604 or in some cases may reside outside the enclosure of 604 as is indicated at 606.
  • elements such as the vacuum regulator 610, ejector 612, flowmeter 614, rate valve 616, and leak detector 618 may be included in the enclosure of 604 or 606 or may, in some cases, be located outside of either or both.
  • the system requires only a flexible power cord for trickle charge ofthe battery backup, which makes the assembly totally portable when not in use.
  • Placement ofthe system container can be accomplished by connection to the cylinder valve, a permanent stand, or a movable stand on casters.
  • Motor and controls are accomplished through an on-board microprocessor with integral LED displays for "CLOSED,” “ALIGN,” and “OPEN” indicators. Programming is accomplished through an integral keypad. Actual valve position is transmitted to the microprocessor from a direct-coupled potentiometer.

Abstract

La présente invention concerne un système permettant de remplir ou de vider des vérins hydrauliques ou à gaz comprimé montés sur la bouteille. Cette invention concerne plus précisément un système automatique permettant de remplir et de vider un vérin (200) à gaz comprimé, et plus particulièrement des vérins à chlorine (2), à dioxyde de soufre ou à ammoniac (4). Ce système comprend un moteur électrique (404) qui fait tourner le système de robinet (430) de la bouteille en position ouverte ou fermée sans perturber des adaptateurs additionnels ou sans que la présence de ces derniers soit nécessaire pour remplir ou vider le matériel.
