For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of straight-through type electromagnetic shut-off valve, comprise valve body, the air inlet connections and the air outlet joint that are installed in the valve body left and right sides respectively and communicate with its inner valve pocket, be fixedly set in electromagnetic coil and coil rack thereof on the valve body, it is inner and can move left and right the movable sealing piece of opening encapsulation and movable set be carried out on valve body and magnetic texure that can move left and right in the air outlet to be positioned at described valve pocket, described valve body, air inlet connections and air outlet joint are formed straight-through body, described magnetic texure carries out magnetic with electromagnetic coil and movable sealing piece respectively and cooperates, it is characterized in that: described movable sealing piece corresponding with described valve pocket structure and its outside laterally have a plurality of equally distributed vent slots, movable sealing piece right side is provided with the spherical sealing surface that is used with the air outlet.
Described magnetic texure is ferrite bead or magnetic Nd-Fe-B ring.
Described valve pocket is a cylindrical shape, and the movable sealing piece is a cylindrical shape.
Described magnetic texure arranged outside has protecting cover; Protecting cover and air outlet joint be mutually on the inwall of fit part, is provided with to guarantee that described magnetic texure and protecting cover can only move forward and backward and the lug boss that can not rotate, and described air outlet joint arranged outside has the groove that matches with lug boss.
The utility model compared with prior art has the following advantages, and 1, simple and reasonable, appearance design is elegant in appearance and install and use easy; 2, use easy to operately and safe and reliable, good seal performance can occur closing automatically when unusual at gaseous-pressure, guarantees the safe handling of domestic gas pipeline.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Embodiment
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the utility model comprises valve body 2, the air inlet connections 1 and the air outlet joint 10 that are installed in valve body 2 left and right sides respectively and communicate with its inner valve pocket, be fixedly set in electromagnetic coil 4 and coil rack 3 thereof on the valve body 2, it is inner and can move left and right the movable sealing piece 6 of opening encapsulation and movable set be carried out on valve body 2 and magnetic texure that can move left and right in air outlet 9 to be positioned at described valve pocket, described valve body 2, air inlet connections 1 and air outlet joint 10 are formed straight-through body, and described magnetic texure carries out magnetic with electromagnetic coil 4 and movable sealing piece 6 respectively and cooperates.Wherein, described movable sealing piece 6 corresponding with described valve pocket structure and its outside laterally have a plurality of equally distributed vent slots 7, movable sealing piece 6 right sides are provided with the spherical sealing surface 11 that is used with air outlet 9.Its magnetic texure is ferrite bead or magnetic Nd-Fe-B ring 5.
In the present embodiment, described valve pocket is a cylindrical shape, and movable sealing piece 6 is a cylindrical shape.In addition, the magnetic texure arranged outside has protecting cover 8; Protecting cover 8 and air outlet joint 10 be mutually on the inwall of fit part, is provided with to guarantee that described magnetic texure and protecting cover 8 can only move forward and backward and the lug boss 12 that can not rotate, and described air outlet joint 10 arranged outside have the groove 13 that matches with lug boss 12.
To sum up, air inlet connections 1 and air outlet joint 10 respectively correspondence be contained on the domestic gas pipeline and the two all adopts permeability magnetic material; Valve body 2 adopts non-magnet material, and an end of its valve body 2 is connected on the air inlet connections 1, and the other end is connected on the air outlet joint 10.Electromagnetic coil 4 is sleeved on the side of valve body 2 near air inlet connections 1, cooperate with magnetic texure and electromagnetic coil 4 magnetic and in valve body 2 inner valve pockets movable sealing piece 6 arranged outside of move left and right a plurality of equally distributed vent slots 7 are arranged, in the present embodiment, the quantity of described vent slot 7 is that 6 and this vent slot 7 communicate with the gas passage of gas pipeline of living in.Described magnetic texure is sleeved on valve body 2 outsides and its outside is set with protecting cover 8, and described magnetic texure and protecting cover 8 can only move forward and backward and can not rotate at the valve body 2 and air outlet joint 10 outsides.
