Description
Technical field
The utility model relates to pipeline valve field, a kind of specifically magnetic-type check valve.
Background technique
There is no the obstruction of check valve, snake, mouse, worm ant etc. are easily entered in family by sewer, closestool and squatting pan, mouse,
Worm ant etc. carries a large amount of germs, influences indoor sanitation, and mouse also often destroys furniture and appliances, brings huge damage
It loses, snake can climb out of from closestool or squatting pan and hurt sb.'s feelings sometimes.
Organic matter decomposition is also easy to produce a large amount of biogas in sewer, and biogas belongs to flammable explosive gas, when biogas explodes
When will lead to the refluence of a large amount of sanitary sewages and enter the room, cause indoor sanitation to be deteriorated, cleaning work is heavy, brings many
Inconvenience, if when blow-up people going to toilet be easy injury, and lack on the market it is a kind of can prevent sewage flow backwards
Product.
Summary of the invention
It can prevent snake mouse from entering the room by sewer the purpose of this utility model is to provide one kind and prevent sewage from falling
The check valve of stream, the technical solution of the utility model are:
Including valve body and valve, the valve inner is equipped with valve retaining ring, and the valve inner retainer is equipped with retaining ring magnet；
The valve is divided into left valve and right valve, and the left valve and right valve can be around center axis rotation, the both ends of the central axis
It is fixed on valve body, the left valve and right valve flange part are equipped with valve magnet, the valve magnet and retaining ring magnet magnetic
Property is attracting, and the pole orientation of the valve magnet on the left valve is identical as the valve magnet poles direction on right valve.
Further, the left valve and right valve internal are additionally provided with secondary magnet, the magnetic of the secondary magnet on the left valve
Extreme direction is identical as the pole orientation of secondary magnet on right valve.
The utility model realizes the normally closed of valve using the principle of magnet " with different suction is denounceed ", and it is dirty to live from indoor discharge
When water, the thrust that a certain amount of sewage generates on valve can push valve open and realize automatic pollution discharge, and with the discharge of sewage
Sewage is gradually reduced the thrust of valve, the valve when the thrust that sewage generates is less than the resultant force of magnetic force between valve and valve retaining ring
Door is automatically closed.
It is simple using the magnetic-type one-way valve structures of the utility model, it is not susceptible to block, be overhauled even if blocking occurs
It is comparatively simple, it can be used for the more sewer pipe of impurity dirt, prevent sewage inside sewer pipe pipeline from flowing backwards, can also prevent snake
Mouse worm ant passes through sewer pipe and enters the room.
Detailed description of the invention
Fig. 1 is the sectional view when valve of the magnetic-type check valve of the utility model is closed.
Fig. 2 is A-A when the valve of the magnetic-type check valve of the utility model is closed to sectional view.
Sectional view when Fig. 3 is the valve opening of the magnetic-type check valve of the utility model.
Fig. 4 is the main view of the magnetic-type check valve of the utility model.
Fig. 5 is the left view of the magnetic-type check valve of the utility model.
Fig. 6 is the right view of the magnetic-type check valve of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
It should be understood that the left and right valve of the magnetic-type check valve of the utility model is from the visual angle of Fig. 5 i.e. left view
Visual angle distinguish left and right.
Referring to Fig. 1 and Fig. 2, the purpose of this utility model is to provide one kind can prevent snake mouse from entering the room by sewer
With the check valve for preventing sewage from flowing backwards, including valve body (1) and valve (7), the valve body (1) is internal to be equipped with valve retaining ring (2),
Retaining ring magnet (3) are equipped with inside the valve retaining ring (2)；The valve (7) is divided into left valve (9) and right valve (10), described
Left valve (9) and right valve (10) can be rotated around central axis (8), and the both ends of the central axis (8) are fixed on valve body (1), institute
It states left valve (9) and right valve (10) marginal portion is equipped with valve magnet (5), the valve magnet (5) and retaining ring magnet (3) magnetic
Property attracting, valve magnet (5) magnetic pole in the pole orientation of the valve magnet (5) on the left valve (9) and right valve (10)
Direction is identical.
Further, it is additionally provided with secondary magnet (6) inside the left valve (9) and right valve (9), on the left valve (9)
Secondary magnet (6) pole orientation it is identical as the pole orientation of secondary magnet (6) on right valve (10).
When in use, sanitary sewage enters from valve retaining ring (2) side, and sanitary sewage pushes left valve (9) and right valve open
(10), left and right valve opens channel around central axis (8) back rotation, and sanitary sewage is big by the thrust that rear left and right valve is subject to
It is big to reduce, when the magnetic repulsive force between the valve magnet (5) that thrust is less than left and right valve between secondary magnet (6), left,
Right valve is magnetic between valve magnet (5) and retaining ring magnet (3) attracting to keep normal around central axis (8) closed rotary pipeline forward
Closed state.When sanitary sewage enters from valve retaining ring (2) other side, the left valve of blocking (9) and the right side due to valve retaining ring (2)
Valve (10) can not be rotated around central axis (8), can not push valve (7) i.e. sanitary sewage open and will not flow backwards entering the room, likewise,
Snake mouse worm ant etc. can not also cross valve and enter the room.
Finally, it is stated that: above embodiments are merely to illustrate the technical solution of the utility model, rather than limit, although ginseng
The utility model is described in detail according to previous embodiment, those skilled in the art should understand that: it is still
Can modify to technical solution documented by previous embodiment, or some or all of the technical features are carried out etc.
With replacement, and these are modified or replaceed, it does not separate the essence of the corresponding technical solution the utility model embodiment technical side
The range of case.
