Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details.
A kind of two float-ball type fire-fighting air-stopping valve door device, as depicted in figs. 1 and 2, it is a kind of machinery valve being applicable to energy recloser in fire protection gas pressure water tank, prevent when for fire-fighting initial attack, in fire protection gas pressure water tank, liquid is drained, pressurized gas is continuously introduced in fire_fighting pipe network, does not only have fire extinguishing function, and the phenomenon playing combustion-supporting effect on the contrary occurs.Adopt this device, can pressurized water in fire protection gas pressure water tank drained time, timely self acting stop valve body, prevents pressurized gas from flowing into fire_fighting pipe network.Its concrete structure is: under spool, valve base flange 5 is equipped with in the bottom of seat 4 and valve ectosome 6, valve ectosome 6 is provided with valve water intake 7, under the bottom at the spool seat of honour 3 and spool, the corresponding part on the top of seat 4 makes at 45 ° domatic 2 respectively, guide rail 1 is being provided with between the valve ectosome 6 and the spool seat of honour 3 on valve water intake 7 top, the bottom of ball float A11 is provided with floating ball rod A10, the bottom of ball float B12 is provided with floating ball rod B13, the kinematic link fixed hole 15 that the bottom of kinematic link 8 has through the circle centre position of valve ectosome 6 is fixed on the spool seat of honour 3, the top of kinematic link 8 is flexibly connected by the middle part of bolt with floating ball rod A10, the bottom of ball float support 9 is fixed on the top of valve ectosome 6, the bottom of floating ball rod support 14 is fixed on the outer end of valve ectosome 6, floating ball rod A10 is connected by the top movable of bolt with floating ball rod support 14 through the hole of ball float support 9 bottom, floating ball rod B13 is flexibly connected with floating ball rod A10 by bolt through the hole on ball float support 9 top.In Fig. 1, a, b, c place is a connecting rod upper shed, and another connecting rod passes and pins with bolt, is formed and is flexibly connected.
What the present invention utilized is law of buoyancy, and when not having liquid in tank, due to the effect of pressurized gas and water outlet pressure difference in gravity and tank, the spool seat of honour 3 is tightly closed with seat 4 under spool, and air-stopping valve is in automatic closed condition.When current are by valve base flange 5, due to hydraulic pressure effect, the spool seat of honour 3 is lifted, current flow in tank by valve water intake 7, now, are because the effect of water filling hydraulic pressure impels air-stopping valve to open, but this state is External Force Acting, does not reach unlatching truly.When liquid level rises to ball float A11, along with liquid level rises, ball float A11, ball float B12 rise in succession, produce buoyancy, ball float A11 is connected with kinematic link 8 by floating ball rod A10, kinematic link 8 is pulled by floating ball rod A10, make the spool seat of honour 3 start to rise, reach unlatching effect, ball float B12 pulls ball float A11 by floating ball rod B13 simultaneously, increase and pull buoyancy, by floating function, pull the spool seat of honour 3, overcome Action of Gravity Field, make valve reach unlatching truly, form the conducting of valve.When pot liquid discharged by needs, when water level decreasing is to ball float B12, ball float A11, ball float B12 declines gradually, the buoyancy acting on the spool seat of honour 3 slowly disappears, due to positive pressure and Action of Gravity Field own, the spool seat of honour 3 starts to decline, guide rail 1 is the annulus of internal diameter less times greater than the spool seat of honour 3 external diameter, the spool seat of honour 3 is by the constraint of guide rail 1, accurately drop to and close with seat under spool 4, under the bottom at the spool seat of honour 3 and spool, the corresponding part on the top of seat 4 makes domatic 2 shapes at 45 ° respectively, therefore, 45 ° domatic 2 bottom the spool seat of honour 3 with spool under 45 ° domatic 2 of seat 4 top closed time, considerably increase area of contact for 45 ° domatic 2, reach the effect of sealing, define the state that valve is closed automatically.This device can overcome the reaction force of current siphon effect to valve body, state is held open when the state of water level higher than ball float, when water level decreasing is to ball float position, valve body is closed automatically, play only gas effect, in water level decreasing process, because ball float A11 is connected with kinematic link 8 by floating ball rod A10, ball float B12 is connected with ball float A11 by floating ball rod B13 simultaneously, considerably increase the pulling force of kinematic link 8, overcome because current are too fast, the siphonage that inside and outside pressure difference is large and cause, can fire-fighting water be smooth and easyly made to get rid of, prevent pressurized gas to enter the damaging effect of fire_fighting pipe network simultaneously.
