Abstract
The utility model provides a kind of built-in negative-pressure drainage means, and negative pressure type drainage means is placed in water-closing-barrel inside, and its structure comprises: hanger, end socket, staving, breathing pipe, selector valve, guide rod and floating drum; Be connected with water-closing-barrel ambient atmosphere through breathing pipe on the upside of selector valve, be connected with floating drum through conduit on the downside of selector valve; By the sink-float of the elevating control floating drum of water level, indirectly controlled the switch of selector valve by guide rod, thus make water-closing-barrel energy Auto-drainage, with the height of controlling water level.Negative pressure type drainage means is placed in interior of bucket by the utility model, makes equipment overall structure more simple, and component reduce, and production technology is more simple and convenient; The adjustment of device structure, cost of production is obviously reduced, and manufacturing efficiency is also greatly improved; In use, it is convenient to settle, and floor space reduces.
Description
Technical field
The utility model relates to a kind of drainage means, especially a kind of built-in negative-pressure drainage means.
Background technique
The negative-pressure drainage device used at present, all adopts external negative-pressure drainage device, is independently negative-pressure drainage device is installed on water-closing-barrel outside.The negative pressure ventilation mouth of drainage means is connected with flexible pipe with the ventilating hole of water-closing-barrel upper end, and water intake is connected with the drain opening of water-closing-barrel lower end, forms similar connecting vessels structure; Adopt selector valve to regulate air pressure in negative-pressure drainage device, keep negative-pressure drainage device internal air pressure, balance between water-closing-barrel internal air pressure and barometric pressure three, reach the object of draining.But for the extra negative pressure type drainage means increased, add processing cost undoubtedly; The overall amount of parts of device is many, processed complex; Require also higher to installation environment in installation process.
Model utility content
Technical problem to be solved in the utility model is: current used negative-pressure drainage device mostly is external, requires high, take up an area wider to installation environment; Overall amount of parts is many, processed complex; Cost of production is high, efficiency is low, and the shipment cycle is long, is difficult to the demand adapting to the development of present market competition.
For above technical problem, the technological scheme that the utility model adopts is: provide a kind of built-in negative-pressure drainage means, negative pressure type drainage means is placed in staving inside, and its structure comprises: hanger, end socket, staving, breathing pipe, selector valve, guide rod and floating drum form; Wherein be connected with water-closing-barrel ambient atmosphere with breathing pipe on the upside of selector valve, be connected with floating drum through guide rod on the downside of selector valve, by the sink-float of the elevating control floating drum of water level, and then indirectly controlled the switch of selector valve by guide rod, thus make water-closing-barrel energy Auto-drainage, with the height of controlling water level.
The beneficial effects of the utility model are: negative pressure type drainage means is placed in interior of bucket, make equipment overall structure more simple, and component reduce, and production technology is more simple and convenient; The adjustment of device structure, cost of production is obviously reduced, and manufacturing efficiency is also greatly improved; In use, it is convenient to settle, and floor space reduces.
Accompanying drawing explanation
Fig. 1 is the structural representation of built-in negative-pressure drainage means;
In figure: 1, hanger; 2, end socket; 3, breathing pipe; 4, selector valve; 5, guide rod; 6, floating drum; 7, staving.
Embodiment
As shown in Figure 1, the built-in negative-pressure drainage means of design, its structure comprises hanger 1, end socket 2, breathing pipe 3, selector valve 4, guide rod 5, floating drum 6 and staving 7 and forms, wherein be connected with water-closing-barrel ambient atmosphere with breathing pipe 3 on the upside of selector valve 4, be connected with floating drum 6 through guide rod 5 on the downside of selector valve 4, by the sink-float of the elevating control floating drum 6 of water level, and then indirectly controlled the switch of selector valve 4 by guide rod 5, thus make water-closing-barrel energy Auto-drainage, with the height of controlling water level.
More current used negative pressure type drainage means, negative pressure type drainage means provided by the utility model, its agent structure is placed in interior of bucket, saves the installing space of self, and structure is simple, and component are few, and production technology is more simple and convenient; The adjustment of device structure, cost of production is obviously reduced, and manufacturing efficiency is also greatly improved.
Claims (1)
1. a built-in negative-pressure drainage means, is placed in staving inside by negative pressure type drainage means, and its structure comprises: hanger, end socket, staving, breathing pipe, selector valve, guide rod and floating drum; It is characterized in that: be connected with water-closing-barrel ambient atmosphere through breathing pipe on the upside of selector valve, be connected with floating drum through conduit on the downside of selector valve; By the sink-float of the elevating control floating drum of water level, indirectly controlled the switch of selector valve by guide rod, thus make water-closing-barrel energy Auto-drainage, with the height of controlling water level;
Described water-closing-barrel end socket is circular arc end socket, and end socket top splits two hangers.
