The operating principle of this double-sealing vacuum eliminator:
This TVS is connected with the pot with no negative pressure of secondary pressurized equipment water inlet end, work point four states: laminate state, anti-negative pressure state, guard mode, pressure detecting and display state.
Laminate state: when municipal ductwork pressure is greater than demand pressure, tap water enters in pot with no negative pressure, along with the rising of tap water water level, in tank, the flange through hole of air on primary seal chamber, mounting flange, secondary seal chamber, cover plate through hole are discharged in casing assembly inner chamber, then are discharged in air by air filter; When tap water water level reaches primary seal chamber, primary seal ball floats, and along with water level, going up one level ball sealer and filter cylinder seal road and coordinate airtight primary seal chamber always.
Anti-negative pressure state: when municipal ductwork pressure is less than demand pressure, in pot with no negative pressure, water compensates demand, and water level decreasing, when water level is down to certain position, primary seal ball in primary seal chamber falls, and air enters in pot with no negative pressure and reaches the effect preventing negative pressure from producing.
Guard mode: when primary seal chamber normally works; secondary seal chamber is in stand-by state always; when primary seal chamber fault or hydraulic pressure is lower there is seepage time; the secondary seal ball of inside, secondary seal chamber floats; along with water level rising secondary seal always ball coordinates airtight secondary seal chamber with cover plate, reach the effect of two protection, now; water level detecting probe in secondary seal chamber detects water level position, and is fed back to controller by this Signal transmissions and carry out alarm.
Pressure detecting and display state: pressure sensor gathers pressure information in tank by the inspection pressure pipe of straight-through pot with no negative pressure, and force value is presented on digital display regulator.Digital display regulator can regulate water enter preventing termination of pumping force value according to municipal demand, and reaches the object of protection municipal ductwork pressure.
This double-sealing vacuum eliminator, multi-functional, technique is advanced, dependable performance, adopt the double seal of double cavity structure and particular design and reach the object that tap water pipe network secondary pressurized laminates and prevent negative pressure from producing.Pressure-detecting device on double-sealing vacuum eliminator device, condensate tank of dehumidifier, digital display regulator and warning system well achieve the protection of ductwork pressure and improve equipment reliability of operation, can be widely used on water supply pipe second pressure water supply equipment.
Primary seal ball and secondary seal ball adopt environment-friendly silica gel material vacuum injection molded, and the chloride ion corrosion in tap water is unaffected to ball sealer, instead of the ball float of prior art stainless steel from material and performance.The concentric reducing structure of primary seal cavity and primary seal ball matching design, well reach sealing effectiveness.The design of secondary seal cavity body structure and secondary seal ball misplace cooperations up and down, reach the effect of closedown secondary seal cavity when secondary seal ball rises, and open secondary seal cavity and can ventilate with primary seal cavity or the function of water during the decline of secondary seal ball.Pressure sensor, by inspection pressure pipe, detects the pressure of tap water water inlet pipe network in real time and force value is presented on display regulation device.Digital display regulator can regulate force value and feeds back to controller system and reach the object protecting ductwork pressure.Primary seal cavity is opened and is closed reciprocal running under normal circumstances, but during primary seal cavity seal failure, the water level detecting probe of secondary seal cavity detects and feeds back signal to controller system and carry out alarm.
