Summary of the invention
The utility model to provide a kind of and aspirates dirt by vacuum in order to solve the problems of the technologies described above, and adopts pneumatic control to realize effluent discharge, and structure and control are all very simple, and the vacuum drain valve that reduces cost.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the utility model comprises the valve seat that is provided with an inlet and an outlet, one opening is arranged on the described valve seat, be covered with valve bonnet on the opening, be stamped valve gap on the valve bonnet, be provided with in the valve bonnet towards the projecting inward tortoise bowl of the opening of valve seat, valve bonnet is interior, the top of tortoise bowl is provided with the vacuum capsule that has the vacuum source import, and the bottom of described vacuum capsule links to each other with the bottom of described tortoise bowl.Gas in the vacuum capsule discharges or sucks by the vacuum source import, thereby changes the gas pressure in the vacuum capsule.When being vacuum in the empty pocket surely, the vacuum capsule shrinks, and the tortoise bowl is risen, and then entrance and exit is communicated with, and vacuum drain valve is in open mode.When the empty pocket of taking seriously was communicated with atmosphere, the vacuum capsule expanded, and under the pushing effect of spring, the tortoise bowl was descended and the partition entrance and exit, and vacuum drain valve is in closed condition.
As preferably, the bottom of described vacuum capsule is connected with wedge, and the wedge bottom is connected with pull bar, and described pull bar is fixed on the bottom of described tortoise bowl, and the position that described valve seat is relative with the tortoise bowl is provided with inner fovea part.The contraction or expansion of vacuum capsule passes to the tortoise bowl by wedge, pull bar with power, realizes the interlock of tortoise bowl and vacuum capsule.Inner fovea part on the valve seat cooperates with tortoise meander face, guarantees to realize the quick opening and closing of vacuum drain valve.
As preferably, be connected with spring between described wedge and the described valve gap.When vacuum drain valve was closed, the vacuum capsule expanded, and adds the effect of the reseting elasticity of upper spring, and the tortoise bowl descends rapidly and cuts off entrance and exit.Spring guarantees that closing of vacuum drain valve is rapider.
As preferably, described wedge comprises that the center is provided with the last disk of through hole and is connected in the hollow cylinder of disk below; The coaxial setting of casing that is provided with in the hollow cylinder, setting of casing passes the through hole of disk, and the bottom of described valve gap is provided with sleeve pipe, and the lower end of last sleeve pipe is enclosed within the setting of casing, and described spring housing is outside last sleeve pipe and setting of casing; The side of hollow cylinder is provided with symmetrical support, and support links to each other with described pull bar; The described disk of going up links to each other with the bottom of described vacuum capsule.The interlock of guaranteeing tortoise bowl and vacuum capsule is flexible, the rising of tortoise bowl or descend not only rapidly but also steady.
As preferably, be provided with the vacuum intake near described exit on the described valve seat, described vacuum intake links to each other with described vacuum source import by air valve.During use, the outlet of vacuum drain valve links to each other with the dirt sucking tube of vacuum delivery pump, the vacuum delivery pump is evacuated dirt sucking tube, after opening air valve, the vacuum capsule is communicated with dirt sucking tube by vacuum source import, air valve, vacuum intake, air pressure descends rapidly and shrinks, thereby makes vacuum drain valve be in open mode.
As preferably, described wedge is provided with two pinch rollers that protrude downwards, and the valve seat wall that described valve seat is positioned at the relative side of pinch roller is provided with a projection that can snap between two pinch rollers.When the tortoise bowl drops to lowest order, be subjected to the pushing of two pinch rollers above, and the part that the tortoise bowl is positioned between two pinch rollers is subjected to upward pushing up of projection, both shortened tortoise bowl stroke, make the tortoise bowl can cut off valve seat more quickly, improve the sealing of cutting off simultaneously again, make closing of vacuum drain valve more reliable.
As preferably, described projection is located on the described inner fovea part.Further shorten tortoise bowl stroke, make closing not only fast but also sealing of vacuum drain valve.
As preferably, described valve bonnet is a taper barrel, and the valve bonnet inwall is provided with two guide rails longitudinally symmetrically, and the left and right sides of described wedge is provided with the slide block that can slide up and down in described guide rail, and described valve bonnet wall is provided with air-vent.Air-vent makes vacuum capsule in the valve bonnet communicate with atmosphere with part between the tortoise bowl, reduces the resistance about the tortoise bowl, make vacuum drain valve open or close rapider.The setting of guide rail guarantees that wedge stably rises or descends, and avoids the phenomenon that shake occurs or wave in process of rising or falling on a vertical direction.
As preferably, described entrance is provided with sealing ring.Sealing ring is guaranteed the sealing that more becomes that is connected of inlet with the waste removal equipment (as toilet) of vacuum drain valve.
As preferably, described tortoise bowl is the rubber material, and the edge card of tortoise bowl is in the junction of valve seat and valve bonnet; Described vacuum capsule is the rubber material, and the edge card of vacuum capsule is in the junction of valve bonnet and valve gap.Guarantee vacuum capsule contraction or expansion freely, the tortoise bowl rises or descends flexibly, and the edge of tortoise bowl, vacuum capsule plays the effect of sealing ring again simultaneously, guarantees the sealing of the connection between valve gap and valve bonnet, valve bonnet and the valve seat.
The beneficial effects of the utility model are: by the rising or the decline of variation of gas pressure control tortoise bowl in the vacuum capsule, on-off between the entrance and exit of realization valve seat, be the unlatching of vacuum drain valve or close, structure and control are all very simple, it is convenient to realize, open and close all very rapid, and easy installation and reliable, sewage effluent and to isolate the effect of foul smell remarkable.
