Embodiment Construction

[0078] Hereinafter, the breather valve and drain pipe system of this invention are demonstrated in detail based on embodiment. exist Figure 1~Figure 3 , shows the first embodiment of the breather valve of the present invention. The breather valve (hereinafter referred to as the valve body 1) is set on Figure 6 The drainpipe system shown (hereinafter referred to as system body 2).

[0079] exist Figure 6 Among them, the system main body 2 is arranged between the outer wall 5 and the inner wall 6 of individual houses or collective houses, for example, and the valve main body 1 is arranged to pass through the ceiling ventilation pipe that extends from the drain pipe 3 to a position lower than the ceiling 7. 4 or the lower part of the overflow edge (あふれ縁) of the drainage equipment can eliminate the negative pressure generated in the drainage pipe 3 through the system main body 2. In this embodiment, an example in which the valve main body 1 is provided in the overhead vent ...

Abstract

To provide a vent valve and drain pipe system that can be installed in approximately the same piping space as the vent pipe to prevent enlargement in the direction of the pipe diameter with a simple structure, and perform well under atmospheric pressure or positive pressure. The valve body maintains the closed state while maintaining high sealing performance. When negative pressure occurs, the valve body operates with high responsiveness while suppressing the ventilation resistance to a small level and ensuring a large ventilation volume, suppressing the oscillation phenomenon and Effectively eliminate negative pressure. The valve is provided so that the valve can be freely opened and closed by a disc-shaped valve body (23) rotatably built in the cylinder main body (20) via a rotating shaft (24). The disk-shaped valve body (23) generates an unbalanced torque rotating in the valve-opening direction via the rotating shaft (24) when the cylinder body (20) is under negative pressure, and can suck air from the outside. The inside of the cylinder body (20) is configured to be in a valve closed state by generating an unbalanced torque rotating in a valve closing direction via a rotating shaft (24) under atmospheric pressure or positive pressure.

Description

technical field [0001] The present invention relates to a breather valve and a drainpipe system connected to a drainpipe to eliminate negative pressure generated in the drainpipe. Background technique [0002] In the past, in the drainage equipment of buildings such as individual houses and collective housing, in order to eliminate the negative pressure in the drainage pipe, protect the backwater trap of the drainage device and seal the water, and drain the water smoothly, a drainage pipe system using a vent valve is generally known. [0003] As a vent valve used in such a drain pipe system, for example, a safety valve disclosed in Patent Document 1 is disclosed. In this valve, the structure is set as follows: two concentric valve seats are provided in the inner chamber of the shell connected to the ventilation pipe, and the valve body with the ring-shaped sealing member installed on the sleeve (ブブ) is opposed to the valve seat. Lifting and lowering, the flow path for sucti...
