Abstract
The utility model relates to a backsiphonage venting device of a soil pipe and a sewage pipe of a sanitary unit. The backsiphonage venting device of the soil pipe and the sewage pipe of the sanitary unit comprises a gooseneck pipe and a venting device, wherein the sewage pipe and the soil pipe are respectively connected with one end of the gooseneck pipe, and the venting device is connected with the other end of the gooseneck pipe. The venting device is composed of a venting pipe and a seal baffle, wherein one end of the venting pipe is communicated with the gooseneck pipe, a plurality of venting holes are arranged in an end face on the other end of the venting pipe, the seal baffle is arranged in the venting pipe and is parallel to end faces of the venting holes, and the seal baffle is in a state of pressing and sealing the plurality of venting holes or in a state of leaving and opening the plurality of venting holes. The backsiphonage venting device is material-saving, easy to manufacture, low in volume production cost, convenient to install, capable of saving a large amount of labor cost, and suitable for utilization in ships of all kinds.
Description
Technical field
The utility model relates to a kind of equipment of Vessel, is a kind of sanitary unit soil pipe that prevents launching to feel suffocated, sewage pipe backsiphonage gas permeable devices specifically.
Background technology
Ship's space Heisui River pipe and grey water pipe often the phenomenon of feeling suffocated can occur when sanitary unit uses now, cause pipeline obstructed, even stop up, and have a strong impact on result of use.Current design generally is the permeability cell that Φ 60mm is set at the place of feeling suffocated, and will breathe freely simultaneously to cause the top of the good bridge deck of airiness or chimney, and pipe end is provided with copper wire gauze.General ship superstructure is more, need to permeability cell be set at the downpipe of each sanitary unit, from bottom permeability cell is extended and builds top layer to the upper strata, wastes a large amount of tubing, increases the construction working amount.
Summary of the invention
For deficiency of the prior art, the purpose of this utility model provides a kind of simple in structure, and cost of manufacture is low, easy to use, safety, can guarantee effectively that plumbing drain normally discharges, prevent that foul smell from entering the sanitary unit soil pipe in cabin, sewage pipe backsiphonage gas permeable devices.
For achieving the above object, the technical solution adopted in the utility model is: a kind of sanitary unit soil pipe, sewage pipe backsiphonage gas permeable devices, comprise a gooseneck pipe and a gas permeable devices, gooseneck pipe one end is communicated with respectively sewage pipe and soil pipe, the gooseneck pipe other end connects gas permeable devices, it is characterized in that described gas permeable devices is comprised of permeability cell and sealing baffle, permeability cell one end is communicated with gooseneck pipe, permeability cell other end end face is provided with a plurality of breather holes, sealing baffle is arranged in the permeability cell and is parallel to the breather hole end face, and sealing baffle and a plurality of breather hole are pressing sealing breather hole or break away from the breather hole state of opening.
Described gooseneck pipe one end is communicated with respectively sewage pipe and soil pipe through reduced flange, gooseneck pipe, reduced flange and soil pipe concentric.
The utility model utilizes the backsiphonage principle, at sewage pipe during to the soil pipe blowdown, be negative pressure state in the gooseneck pipe, sealing baffle and a plurality of breather hole break away from opens breather hole, allow air to enter pipeline to make discharging unobstructed thereby reach, and blowdown is barotropic state when stopping in the gooseneck pipe, sealing baffle and a plurality of breather hole pressing sealing breather hole stop foul smell to enter the cabin.These device materials are few, make simply, and the batch making cost is low, and is easy for installation, can save a large amount of labor costs, is fit to use on the various ships.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model gas permeable devices structural representation.
Among the figure: sewage pipe 1, soil pipe 2, reduced flange 3, gooseneck pipe 4, gas permeable devices 5, permeability cell 6, breather hole 7, sealing baffle 8.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in Figure 1, a kind of sanitary unit soil pipe, sewage pipe backsiphonage gas permeable devices, comprise a gooseneck pipe 4 and a gas permeable devices 5, gooseneck pipe 4 one ends are communicated with respectively sewage pipe 1 and soil pipe 2 through reducing method 3, the gooseneck pipe other end connects gas permeable devices, gas permeable devices 5 is comprised of permeability cell 6 and sealing baffle 8, permeability cell one end is communicated with gooseneck pipe, permeability cell other end end face is provided with a plurality of breather holes 7, sealing baffle is arranged in the permeability cell and is parallel to the breather hole end face, and sealing baffle and a plurality of breather hole are pressing sealing breather hole or break away from the breather hole state of opening; Gooseneck pipe, reduced flange and soil pipe concentric.
When the sanitary unit draining, when sewage is delivered to the soil pipe discharging by sewage pipe, make and produce negative pressure in the gooseneck permeability cell, outside barometric pressure forces sealing baffle to rise in permeability cell, sealing baffle breaks away from the breather hole of permeability cell end face, thereby extraneous air is able to enter the gooseneck permeability cell by breather hole, reaches the purpose of smooth discharge in the soil pipe.When sanitary unit stops draining, the sewage pipe return-air, make the gooseneck permeability cell consistent with outside barometric pressure, sealing baffle falls back on the breather hole under Action of Gravity Field, because the sealed baffle plate sealing of breather hole, thereby make foul smell and extraneous air actv. in the gargle pipe isolated, reach the purpose that stops foul smell to enter the cabin.
Claims (2)
1. a sanitary unit soil pipe, sewage pipe backsiphonage gas permeable devices, comprise a gooseneck pipe and a gas permeable devices, gooseneck pipe one end is communicated with respectively sewage pipe and soil pipe, the gooseneck pipe other end connects gas permeable devices, it is characterized in that: described gas permeable devices is comprised of permeability cell and sealing baffle, permeability cell one end is communicated with gooseneck pipe, permeability cell other end end face is provided with a plurality of breather holes, sealing baffle is arranged in the permeability cell and is parallel to the breather hole end face, and sealing baffle and a plurality of breather hole are pressing sealing breather hole or break away from the breather hole state of opening.
