Description
The utility model relates to a kind of gas relief valve.
Existing utility model patent CN2199458Y discloses a kind of gas safety automatic controller, and its controlled gas valve comprises valve body, valve gap, coil assembly, moving iron core, lid, axle, seal membrane, and its shortcoming is this valve body processed complex.
The order point of the utility model provides a kind of gas safety cut-off valve simple in structure, easy to process.
The technical solution of the utility model is: be made of housing, the cap that has the movable chamber of controlling rod, rubber membrane, controlling rod, handle, control spring, manual thimble and electromagnet assembly, the end, be provided with a vertical drum post in the described housing, this drum post upper end is a valve port, the side communicates with the inlet opening, at housing with have between the cap in the movable chamber of controlling rod and be provided with rubber membrane; The upper end of described controlling rod is provided with handle, and its stage casing is provided with the groove that matches with the electromagnet dead bolt, matches with valve port by rubber membrane in its lower end, and top, the movable chamber of controlling rod is provided with the spring that acts on controlling rod; Side, the movable chamber of controlling rod is provided with manual thimble.
The utility model has the advantages that simple in structure, easy to process.
Now in conjunction with the accompanying drawings and embodiments the utility model is described as follows:
Fig. 1: be one of cut-away view of the present utility model;
Fig. 2: be two of cut-away view of the present utility model;
The utility model is made of housing 1, the cap 2 that has the movable chamber of controlling rod, rubber membrane 3, controlling rod 4, handle 5, control spring 6, manual thimble 7 and electromagnet assembly 12, the end, be provided with a vertical drum cylinder 8 in the described housing 1, these drum cylinder 8 upper ends are valve port 9, the side communicates with inlet opening 10, at housing 1 with have between the cap 2 in the movable chamber of controlling rod and be provided with rubber membrane 3; The upper end of described controlling rod 4 is provided with handle 5, its stage casing is provided with the groove 11 that matches with electromagnet dead bolt 13, match with valve port 9 by rubber membrane 3 in its lower end, top, the movable chamber of controlling rod is provided with the control spring 6 that acts on controlling rod 4, and side, the movable chamber of controlling rod is provided with manual thimble 7.
Gas stop valve of the present utility model at first upwards spurs handle 5 in use, and electromagnet dead bolt 13 is embedded in the groove 11 of controlling rod 4, and controlling rod 4 is positioned at upper position, and cut-off valve is opened.When gas leakage, 12 work of detection device control electromagnet assembly, electromagnet dead bolt 13 moves backward, and controlling rod 4 moves downward under the effect of control spring 6, by rubber membrane 3 valve port 9 is closed.Manual thimble is the manual-lock device, and when promoting manual thimble 7, it promotes electromagnet dead bolt 13 and moves backward, and under the effect of control spring 6, controlling rod 4 moves downward close port 9.
