Definitions

  • the present invention refers to a device for stopping and restoring the flow of pressure reducers, particularly, but not exclusively, aimed to be used for drinkable water, also for human use.
  • Such stopping device allows locking the flow without modifying the chosen calibration of the downstream pressure upon restoring the flow.
  • the pressure reducer in addition to performing its normal task of reducing and checking the downstream pressure level, also performs the function of stop or intercepting tap, so that it prevents such tap from being installed downstream, and also avoiding that, upon restoring the flow, it is necessary to proceed with the recalibration of the previously-set outlet (downstream) pressure.
  • Object of the present invention is therefore providing a device of the above type with which the correct operation of the downstream plant can also be checked, even without an intercepting tap (that stops the related flow) placed upstream of the same reducer: therefore, after having used the device, it is not necessary to proceed with a new calibration since the previously-set pressure is not subjected to variations.
  • This same device can further be equipped with a plug that, with interrupted flow, has the function of verifying the correct seal of the check (or non-return) valve, since water in drawing taps placed downstream is not allowed, for any reason, to go upstream due to contamination reasons.
  • the device of the invention is used for stopping and restoring the flow of pressure reducers, and substantially comprises:
  • the pin 5' rises and, by means of an interposed washer 4 (equipped with its necessary sealing members), blocks the shutting valve 6, stopping the flow.
  • the pressure reducer also performs the function of intercepting tap (position shown in Figure 2 ).
  • the plug 8 will be re-screwed and with a suitable rotation exerted on the knob 5 (contrary to the previous one), the shutting and regulating valve 6 will be freed, and in such a way, the same previously existing pressure will be re-established downstream, without needing new regulations (return to the position shown in Figure 1 ).
  • the vessel 3 operates therefore as carrier structure for the moving components of the inventive part of the device of the invention: in fact, it housed the thrusting washer 4 together with the knob 5; such vessel 3 can be made both of plastic and of metallic material and can have any shape suitable for its purpose.
  • the knob 5 is the member that transmits the functional movements: it is equipped with a through-hole 14 for the components used for testing, and houses the plug 8, suitable for the plant checks; in particular cases, it could be made also without hole 14 and plug 8.
  • the knob 5 further houses and holds the washer 4, but remains free of rotating inside the washer 4, allowing to transform the rotary movement into a linear (front-back) movement: this in order to avoid the possible unscrewing of the shutting valve 6. Also the knob 5 can be made both of plastic and of metallic material.
  • the washer 4 as seen, is equipped with suitable sealing gaskets and it is the interposed member that exerts the thrust or retracts for closing and opening the flow on the shutting valve 6. Also the washer 4 can be made both of plastic and of metallic material.
  • Figures 4 and 5 show an alternative embodiment of the device of the invention, with a reduced number of sealing members next to the thrusting washer 4.
  • the improvement of this alternative embodiment only affects the thrusting mechanism, and consists in that, in the previously-described version, the pin 5' of the knob 5, receiving the rotation, was lifted and also had to rotate inside the washer 4, while the washer 4, due to friction on an external gasket (not shown), must not rotate in order not to impress an unsuitable rotary movement to the shutting valve 6. After a long period of inactivity of the system, possible frictions could have occurred between knob 5 and washer 4, with the possible transmission of rotary forces (even if weak and scarcely relevant forces) at the base of the shutting valve 6 through the washer 4.
  • the thrusting washer 4 (which, when assembled, becomes a single piece) has a through-hole 14 that allows fluid to pass for the functional tests of the device, as described for the previous embodiment.
  • the device of the present invention is useful since it is not mandatory any more to install an intercepting tap (flow stopping member) upstream: in fact, the pressure reducer of the invention also performs the function of such intercepting tap. This allows verifying and possibly intervening on the downstream plant; moreover, upon re-opening the flow, it is not necessary to proceed with the recalibration of the previously-set pressure. Thereby, more reduced spaces are needed for installing the device of the present invention.
