Definitions

  • the invention relates to a Pressure Regulating system using an underground fluid pressure regulating control module (e.g. for fuel gas) within a pipeline.
  • an underground fluid pressure regulating control module e.g. for fuel gas
  • a complete gas pressure regulator module 110 is provided (see Figure 1) within an underground chamber with all the major control devices being incorporated within the module housing and the module can easily be replaced for maintenance and other purposes. There is access to the module via manhole cover 111.
  • the buried system pipeline will typically include an inlet valve, an outlet valve an a flap type non return valve outside the module.
  • An inlet has a flange 113 (e.g. 150 mm) for coupling to an inlet pipe and a flange 115 (e.g. 200 mm) for coupling to an outlet pipe.
  • a flange 113 e.g. 150 mm
  • a flange 115 e.g. 200 mm
  • the underground module includes a filter 116 through which the gas passes into the chamber and hence to the removable cartridge 112.
  • a slam-shut valve 117 is connected in series with the pressure regulator valve 118.
  • a number of additional components are provided including several pilot valves.
  • the cartridge is pre-assembled and easily replaceable to reduce downtime.
  • Such a regulator control module can typically cope with inlet pressures up to 4 Bar and outlet pressure set to between 20 and 75 mBar with a flow capacity of up to 8,500 m 3 /Hr.
  • a vent stack 130 provides a reference atmospheric pressure point for the cartridge 112 and houses other lines (shown schematically as pipe 131 ).
  • the instrument box 133 contains a chart recorder for inlet and outlet pressures and various test points (e.g. for slam-shut testing).
  • FIG. 2 Such an arrangement is shown in Figure 2 with the slam-shut valve 117 having been omitted for the sake of clarity.
  • the flow pressure is controlled by the main regulator valve 118 and the set point of the valve 118 is provided by pilot valve 120 (K1).
  • the pilot control operates by receiving a pre-regulated supply of gas via the regulator 121 (J) before passing through a restrictor pipe 122 and then through the pilot regulator 120 (K1) before being bled to the outlet main (ignoring optional pilot regulator 123 (K2) for the moment).
  • the main regulator valve 118 receives gas to its control line adjacent the outlet of the restrictor 122.
  • the additional pilot 123 (K2) is provided with a different set point to deal with a different set demand level such as during the night. This will require a clock device 135 with associated valve which is connected to the pilot 123 via a fluid line.
  • the objection of the present invention is to provide a modified arrangement with a more sophisticated control to reflect demand more closely yet be incorporated largely within the underground module.
  • a fluid pressure regulating system including a removable underground regulator module for insertion into an underground chamber in use, said removable cartridge including a main pressure regulator valve and a slam shut safety valve connected in series with the regulator, and control means for providing a plurality of setting parameters during a predetermined period to replicate utilisation requirements and means within the module for responding to said parameters to effect changes in the operation of the main regulator valve within the module to provide a variable desired output pressure to meet utilisation requirements.
  • a method of regulating pressure in a fluid regulating system including a removable underground regulation module cartridge having a regulator valve and slam shut valve therein, the method comprising: monitoring fluid utilisation over a given period in a logging device, providing a plurality of setting parameters during a preset period based on historic utilisation information and controlling the regulation valve within the cartridge by control means to vary the flow output in response to the setting parameters to effect changes to a desired output pressure to meet utilisation requirements.
  • Figure 1 shows an underground pressure regulating module
  • Figure 2 shows a mechanism for controlling output pressure with an incorporated clock mechanism
  • Figure 3 shows a graph of utilisation and output pressure requirements over time
  • Figure 4 shows a modified arrangement with variable pressure regulation
  • Figure 5 shows the logger/control arrangement in more detail.
  • Figure 3 shows pressure graphs for the gas supply.
  • the requirement is to supply customers with a stream of gas at a steady pressure of at least 20 mBar (see Graph (a)).
  • the present invention allows a modified underground module to have a continuously variable pressure setting dependent on previously monitored utilisation at that particular station in the gas supply network.
  • a utilisation profile (see Graph (c)) allows the output availability of (a) to be maintained to meet demand requirements whilst allowing reduced pressure to be selected, hence lowering volume requirements and the likelihood of leakage, etc.
  • the variations of Graph C are shown as being relatively static over any given short period (e.g. one hour) in practice a large number of variations can be accommodated if desired.
  • module cartridge 112 is modified as shown in Figure 4.
  • the pilot valve 123 of Figure 2 has been replaced by a dual diaphragm valve 168 (K DP ) which receives control from a logger/controller 153.
  • the other pilot 120 (K1 ) can be retained if required for safety reasons.
  • a supply governor 157 provides a regulated supply of gas to the control for its use.
  • a needle valve 170 provides a restricted path setting which, should there be a failure of the controller 153, it will act as a fail safe to give a stable controlled output pressure at the predetermined set level.
  • the controller 153 is programmed with information to allow it to impulse the top diaphragm D1 of the valve 168 to cause a variable setting of this valve depended on the previously stored information to allow continuous pressure variation setting to meet the profile of Figure 3(c).
  • control box 150 In practice, to house the controller, an additional box, control box 150 (see Figure 5), is mounted on vent stack 130 below the existing instrument box 133. Lines for operational control are fed through tube 151 from the instrument box 133.
  • the heart of the control arrangement is the controller/logger 153 which can include a microprocessor, memory, clock and display.
  • a modem 154 allows logged information to be received remotely and control information passed to the logger/control 153 from a remote site.
  • Dependent on operational and safety requirements a low pressure slam-open valve 156 and supply pressure regulator 157 can be included.
  • the controller/logger monitors pressure/usage and so receives the gas supply through a small tube at inlet 160. It also uses the gas to operate components and receives this via the supply pressure regulator 157.
  • the outlet 161 passes to the instrument box 133.
  • a control output 163 provides pressure control to the underground regulator via flexible pipe 164 which is the control line also received by the slam-open valve 156. In the event of a fault, when the slam-open valve senses low output it will dump control pressure to the outlet and allow the outlet to rise to the underground regulator preset value
  • Line 165 provides a route to exhaust the gas during setting changes
  • the logger/controller 153 monitors and records information on usage/pressure to allow a profile to be known for that station and this is typically downloaded once every 24 hours following a prompt signal via the telephone link to the modem 154 This information is utilised by a remote computer (not shown) to calculate expected usage requirement and selects a stream of different pressure settings for use throughout the next 24 hours (with a margin for handling a somewhat increased loading) and downloads this via the telephone line to the controller which uses its internal clock to increment and decrement the pressure as previously instructed throughout the day to provide variable pressure control to the cartridge 1 12 so as to produce the results shown in the Graph in Figure 2C for example
  • the logger can also produce alarm and other signals for sending to the remote site via the modem Although a telephone line can be used, radio or other transmission techniques could be utilised
  • the cartridge is easily interchangeable with that of Figure 1 and needs no excavation work because it slides into the existing chamber and is closed using the same bulkhead
