Back-siphonage ventilating device of soil pipe and sewer pipe for sanitary unit

Abstract

The invention relates to a back-siphonage ventilating device of a soil pipe and a sewer pipe for a sanitary unit. The back-siphonage ventilating device of the soil pipe and the sewer pipe for the sanitary unit comprises a gooseneck and a ventilating device. One end of the gooseneck is respectively communicated with the sewer pipe and the soil pipe while the other end of the gooseneck is connected with the ventilating device. The ventilating device consists of a ventilating pipe and a sealing baffle. One end of the ventilating pipe is communicated with the gooseneck while the other end of the gooseneck is provided with a plurality of ventilating holes on the end surface. The sealing baffle is arranged in the ventilating pipe and is parallel to the end surfaces of the ventilating holes. The sealing baffle and the ventilating holes are compressed to seal the ventilating holes or separated to open the ventilating holes. The device consumes less materials, and is simple to prepare, low in manufacturing cost of batch production, convenient to install, and saves a large number of labor cost, and is appropriate for various ships.

Description

technical field [0001] The invention relates to ship equipment, in particular to an anti-siphon air-ventilating device for feces pipes and sewage pipes in a sanitary unit to prevent ships from being held in water. Background technique [0002] Now the black water pipes and gray water pipes in the ship's cabin often suffer from suffocation when they are used in the sanitary unit, causing the pipelines to be blocked or even blocked, which seriously affects the use effect. The current design is generally to set a Φ60mm ventilation pipe at the place where the air is held, and at the same time lead the ventilation to the bridge deck or the top of the chimney with good air circulation, and a copper wire mesh is installed at the end of the pipe. Generally, there are many superstructures in ships, and it is necessary to install ventilation pipes on the downpipes of each sanitary unit, and extend the ventilation pipes from the bottom to the top of the superstructure, which wastes...
