Water inlet, is provided with a plug in the main body runner, and the plug includes magnetic conductor, after the rear end face and main body runner of plug
End surface shape is agreed with；The rear of valve pocket water inlet is provided with the permanent magnet in case body, when water inlet pipe hydraulic pressure is not less than pre-
If during value, by magnetic-adsorption plug automatic fall-back can be made to seal water inlet in the second circular groove.
On the basis of such scheme, further improve or preferable scheme also includes：
The plug includes the magnetic conductor at center and is coated on the elastomeric layer of magnetic conduction external surface, to improve plug
Sealing.
Preferably, the elastomeric layer is tetrafluoro layer.
The magnetic conductor then preferably uses metal ball.
The valve pocket was provided with chute, the front end face or front end face and main body runner crossed chute and be opened in main body runner
In side wall, when plug blocks main body runner front end face, the water inlet can be connected by the chute of crossing with outlet pipe.
The middle part of the main body runner is cylindrical flow, and both ends are the circular groove of evagination, i.e. main body runner and stifled
Front end face, the rear end face of head are arc-shaped surface.
Preferably, the circular groove is set to hemispherical, the plug is the ball with circular groove size fit
Body, when plug rotates, its front/rear end is set to remain to agree with the circular groove.
Beneficial effect：
1）The utility model one-way valve structures are novel, reasonable in design, easy to operate, are readily produced manufacture, and suitable for each
The pipeline of kind installation direction, it is adapted to scope wide；
2）Compared to spring check valve, its long product lifecycle, and maintenance cost is low；
3）By changing the distance of permanent magnet and plug, the Opening pressure of check valve is can adjust, compared to existing check valve,
Its occupation mode is more flexible.

Embodiment
In order to further elucidate the technical solution of the utility model and operation principle, below in conjunction with the accompanying drawings with specific embodiment
Utility model is further introduced.
A kind of Novel check valve as shown in Figures 1 to 6, by shell 1, plug and the control automatically reset permanent magnet of plug
6 grade parts form.
Valve pocket is provided with the shell 1, plug is arranged in the valve pocket, and shell 1 preferably uses non-magnetizer material system
Into such as plastics.
The valve pocket is made up of main body runner 3 with chute 2 is crossed, as shown in Fig. 3, Fig. 4 and Fig. 6, in the main body runner 3
Portion is cylindrical flow, and the both ends of cylindrical flow are the circular groove of evagination, and in the present embodiment, the circular groove is adopted
With with cylindrical flow diameter identical hemispherical, the longitudinal cross-section for making main body runner 3 is in kidney-shaped, and plug is then designed as and circular arc
The spheroid of connected in star shape adaptation, the length of valve pocket are more than the diameter of plug.
The delivery port of the valve pocket is arranged at the front end face center of main body runner 3, and main body runner 3 is arranged on after water inlet
At rear end face center, the delivery port is connected with the outlet pipe of shell 1, and the water inlet is connected with the water inlet pipe of shell 1, front end
Some are provided with the anterior side wall of face or front end face and cylindrical flow and crosses chute 2, as shown in fig. 6, crossing the rear end notch of chute 2
Connected with water inlet, front end notch is reached on the tube wall of outlet pipe, as shown in figure 4, when water inlet pipe hydraulic pressure it is larger, plug is impacted
To valve pocket front end, when agreeing with the front end face of its circular arc, water inlet can be connected by the chute 2 of crossing with outlet pipe, be avoided
Plug blocks the water side of valve pocket.
The center of the plug is spherical metal magnetic conducting body 4, the outer surface cladding tetrafluoro layer of metal magnetic conducting body 4, makes to block up
It is flexible, improve the sealing of plug.
The rear side of valve pocket water inlet is provided with permanent magnet 6 described in the permanent magnet 6 being embedded in the housing of shell 1 and is used to inhale by magnetic force
Attached plug, when water inlet pipe hydraulic pressure is not less than preset value, making plug automatic fall-back, that is, water inlet end is made in the second circular groove
With when the impulsive force on plug is less than permanent magnet 6 and acts on the power sum on permanent magnet 6 with water side to the suction of plug, block up
What head can be stablized rests in the second circular groove, seals water inlet to reach, prevents the purpose of adverse current.The permanent magnet 6
The suction of plug can be changed with range conversion therebetween, so can be changed by the distance for adjusting permanent magnet and plug
Become the Opening pressure of check valve, occupation mode is flexible and manufacturing cost is low.
The shell 1 is made up of two parts docking, and its joint is arranged in the middle part of valve pocket, in order to install replacing plug.
The mode that the both ends of shell 1 are connected through a screw thread is connected with external pipeline system.
"front", "rear" used in the present embodiment understands relative described with reference to valve body for convenience of those skilled in the art
Absolute orientation can change with check valve use environment.General principle of the present utility model, principal character has been shown and described above
And the advantages of the utility model.It should be understood by those skilled in the art that the utility model is not restricted to the described embodiments, on
State and simply illustrate principle of the present utility model described in embodiment and specification, do not departing from the spirit and scope of the utility model
On the premise of, the utility model also has various changes and modifications, and the utility model requires protection scope will by appended right
