In figure: total protective cover 1, mounting flange 2, first class of protection cover 3, ball float 4, lever connecting lever 5, twisted axis 6, sealed valve core 7, sealed valve body 8, one-level installing plate 9, gas are to changing body 10, secondary installing rack 11, air-purifying net 12, probe 13, state display instrument 14, through hole 15, the first through hole 16, the second through hole 17.
The specific embodiment
With reference to Figure of description, negative pressure canceller of the present utility model is described in detail below.
As shown in Figure 1, negative pressure canceller of the present utility model, its structure comprises total protective cover 1, mounting flange 2, first class of protection cover 3, ball float 4, lever connecting lever 5, twisted axis 6, sealed valve core 7, sealed valve body 8, one-level installing plate 9, gas is to changing body 10, secondary installing rack 11, air-purifying net 12, probe 13, state display instrument 14, top and the one-level installing plate 9 of described first class of protection cover 3 are connected, on the top of one-level installing plate 9, be provided with secondary installing rack 11, outer cover at secondary installing rack 11 is connected to total protective cover 1, the bottom of described total protective cover 1 is provided with mounting flange 2, in described first class of protection cover 3 inner chambers and the inner chamber of secondary installing rack 11, be respectively arranged with a ball float 4.
Described ball float 4 one sides are connected with lever connecting lever 5, and described lever connecting lever 5 rotates and stirs sealed valve core 7 around twisted axis 6, and described sealed valve core 7 is built in sealed valve body 8 inner chambers; Ball float 4 is subject to buoyancy of water and drives lever connecting lever 5 to promote to move with sealed valve body 8 and form sealing on sealed valve core 7 around twisted axis 6 rotations.Sealed valve core 7 is provided with the silicagel pad of an arc, has a high-precision sealing surface on sealed valve body 8, has guaranteed tightness.
On the top of one-level installing plate 9, be provided with the gas of change one-level Exhaust Gas direction to changing body 10, avoid directly blowing on the ball float 4 of secondary.
As shown in Figure 2; described total protective cover 1, secondary installing rack 11 and first class of protection cover 3 are cylindric; on the lower circumference wall of total protective cover, the bottom, opposite flank of state display instrument is provided with several through holes; in the circumferential wall on described first class of protection cover top, be evenly provided with circle first through hole 16; the first described through hole 16 is that 8 large aperture through holes are uniformly distributed; in the circumferential wall of bottom, be evenly provided with the second through hole 17, the second described through hole 17 is that 6 small-bore through holes are uniformly distributed.
