Embodiment
Composite lever formula automatic air intake and discharge valve comprises valve body 8, top cover, floating drum 11, floating drum fan housing 10, micro-exhaust sealing mechanism and big exhaust sealing mechanism.Described top cover is fixedly connected main blind flange 4 by top loam cake 1 connection top lower cover 2, top lower cover 2 and constitutes; Top cover covers flange 5 through main blind flange 4 and valve body 8 tops couplet and is connected; Top lower cover 2 is provided with lateral ventilation mouth 3; Main blind flange 4 be provided with vertical ventilated port 16 and with valve body 8 in are communicated with; Be provided with big exhaust sealing mechanism below the vertical ventilated port 16, big exhaust sealing mechanism is contained in the big exhaust bracket 7 that is fixedly connected with main blind flange 4 by big exhaust sealing floating drum 6 and constitutes, and its big exhaust sealing floating drum 6 is slidingly connected through the slide bar 17 of upper end and exhaust bracket 7 set slideways 18 greatly.Also be coated with micro digestion fume tube 15 on the main blind flange 4; Micro digestion fume tube 15 lower ends are provided with micro-exhaust sealing mechanism; Trace exhaust sealing mechanism is made up of micro-exhaust sealing 14, little row's main lever 13 and micro-exhaust level 12, and micro-exhaust sealing mechanism is hinged with the little row's main lever 13 below being positioned at through micro-exhaust sealing 14.Said micro-exhaust level about in the of 12 two ends hinged with micro-exhaust sealing 14 respectively with little row's main lever 13, make micro-exhaust sealing mechanism become the part of little row's main lever structure through micro-exhaust level 12.Be provided with floating drum 11 in the said valve body 8; Floating drum 11 bottoms are contained in the floating drum fan housing 10; Floating drum fan housing 10 is fixing through fan housing support and valve body 8, and floating drum 11 tops and little row's main lever 13 upper ends are hinged, and the other end and micro digestion fume tube 15 1 sides are hinged; Be connected with aqueduct through joining pipe flange 9, constitute composite lever formula automatic air intake and discharge valve.
Working principle
When aqueduct begins transporting water; Gas in the pipeline is in valve port gets into valve body 8; This moment, big exhaust sealing 6 rested under the effect of gravity on the big exhaust bracket 7 all the time, and inner air tube discharges (see figure 3) through the lateral ventilation hole 3 of vertical ventilated port 16 and top lower cover 2.Along with the discharge of gas, water level rises in valve body, and at first floating drum 11 compresses micro-exhaust sealing 14 at water floating function float downward with micro digestion fume tube 15, has sealed micro-exhaust port.Water level continue to rise, and again big exhaust sealing 6 is floated and compresses with main blind flange 4, has sealed the intake and exhaust (see figure 1) of vertical ventilated port 16.In the aqueduct running, occur if any gas, gas can be built up on the top in the valve body 8; The compressing drawdown; Floating drum 11 descends (like Fig. 4, shown in Figure 5), and micro-exhaust this moment is in starting state, under the effect of little row's main lever 13; It is drop-down again that trace exhaust level 12 makes micro-exhaust sealing 14 stick up pressure earlier, opened micro-relief opening.When cutting off the water maintenance during aqueduct, ducted water continues to discharge until producing negative pressure, makes big exhaust sealing 6 to lower slider from the air pressure and the action of gravity of atmosphere, air through valve port to the additional air (seeing shown in Figure 2) of pipeline.
