Definitions

  • the present invention relates to a degassing device intended for the distribution of liquid with metering or volume measurement.
  • the invention further covers a liquid distribution installation comprising said device.
  • the detection of gas which most often happens to be air, takes place by means of a fixed detection probe, such as a thermistor or capacitance, or else by a float which follows the level of the liquid.
  • a fixed detection probe such as a thermistor or capacitance
  • a float which follows the level of the liquid.
  • the control from the float on said cutting means takes place hydraulically, pneumatically or electrically.
  • Document EP-A-0 030 509 in particular discloses an installation for distributing and measuring liquid by gravity provided with a gas detector cooperating with a shut-off valve.
  • the detector in particular comprises a body fitted with an upstream filter and this cannot be accessible without causing air to enter the downstream installation.
  • the aforementioned document moreover essentially concerns bodies intended to ensure automatic management of the coordination between the detector and the shut-off valve in the unique case of gravity distribution and, as a result, the distribution installation itself. even does not present the same means as those intended to solve the problems mentioned above.
  • the device according to the invention comprising in particular a gas detector intended to cooperate with a means for cutting off the flow of liquid, is constituted by a body inclined relative to the axis of its upstream inlet, said inlet communicating with a chamber provided of the detector, the body containing a filter arranged downstream of the detector, the upstream side of which is closed by a removable cover situated upstream relative to said detector and the downstream side is extended by a downstream outlet.
  • the gas detector is constituted by a probe or by a float and the chamber is provided with a pipe for venting the detected gas.
  • the device as defined above is directly connected by its upstream inlet to a reserve of liquid such as a tank compartment loaded on said inlet and, through its outlet, to a counter as well as by means of liquid flow cut-off, a pump which can be interposed between said outlet and the counter, whereby the filter is arranged upstream of the counter and downstream of the detector of the degassing device, while the removable cover of the device is arranged upstream of said detector.
  • a reserve of liquid such as a tank compartment loaded on said inlet and, through its outlet, to a counter as well as by means of liquid flow cut-off, a pump which can be interposed between said outlet and the counter, whereby the filter is arranged upstream of the counter and downstream of the detector of the degassing device, while the removable cover of the device is arranged upstream of said detector.
  • the device according to the invention hereinafter referred to as degasser, comprises an upstream inlet 1 provided with a suitable flange, connected to a body 2 of axis 3 inclined with respect to axis 4 of said entry.
  • the upstream end of the body 2 is provided with a removable cover 5 and its internal downstream part contains a filter basket 6.
  • This downstream part is extended by an outlet 7 provided with a second flange, of axis 8.
  • the inlet 1 further communicates with a chamber 9 via a passage 10, disposed upstream with respect to the filter 6.
  • the chamber is intended for the detection and evacuation of the gas and, for this purpose, it comprises an appropriate detector intended to cooperate, through a suitable relay and a line of control, with a means for cutting off the fluid flow.
  • the chamber 9 also includes a vent pipe 12.
  • the gas detector can be constituted by a float 13 connected to a relay 11A (FIG. 1) or by an appropriate probe known per se 14 connected to a suitable relay 11B (FIG. 2), the control line 15 being connected to the liquid flow shut-off means, as will be better explained below.
  • a liquid distribution installation specific to the degasser 2 is for example connected to a tank compartment 16 under load on its inlet 1, while the pipe for venting 12 leads to the top of said compartment.
  • the installation successively comprises a counter 17 and a valve 18A, constituting the means for cutting the flow of fluid, controlled by line 15.
  • the installation further comprises a pump 19 interposed between the outlet 7 and the counter 17, that is to say that the degasser is disposed before the pump.
  • the outlet 20 of the installation is of course arranged after the valve 18, itself of the type with an opening that can be adjusted by hydraulic, pneumatic or electric control.
  • the gas detector is represented in the form of a float 13 with its relay 11A, but it is obvious that it could be constituted by a suitable probe as illustrated in FIG. 2.
  • the valve associated with the counter 17 can be arranged upstream (18B) or in downstream (18A) of the latter.
  • the degassing device When the degassing device is supplied with liquid, the air escapes through the venting pipe 12, the float 13 is then held by the liquid in the high position, the relay 11A being adjusted so that it opens the valve 18A (B) thus allowing distribution by the general outlet 20.
  • the filter When gas is present, the filter is an element that promotes emulsion, so it is desirable to place it after the place where the gas is detected.
  • the filter must be easy to clean and if it is possible that it is placed in a vacuum, the opening of this filter must not lead to the introduction of outside air which would distort measurement.
  • the device which is the subject of the invention provides both the filter placed downstream of the gas detection and an opening for cleaning this filter upstream of the detection. Thus, in the event of opening of the system in vacuum, the air would be immediately detected and could not lead to a measurement error.
