Abstract
The utility model discloses a gas safety valve relating to the field of valve technique, wherein, an exit of the three-way outlet is provided with an air bag, the other exit thereof is provided with an air valve which is further provided with a leader, the leader is connected with a lever connected with a self-lock device. A tension spring arranged on the air bag is connected with a tie rod, which is also connected with the self-lock device. Compared with the prior art, the utility model achieves energy saving, convenient use, safety, simple structure by using self-mechanical gearing to control the on-off of the air valve.
Description
The utility model belongs to valve technology field, relates to a kind of safety valves for gas.
Biogas coal gas has all been used in present many cities, has brought a lot of convenience, clean hygiene for people's life; But these combustible gases also have certain danger, people cook have a bath the heating in, can stop the supple of gas or steam suddenly, forget the pass gas check valve easily, easily cause the accident.
The purpose of this utility model is a kind of easy to use, simple in structure, economical gas safety valve of stopping the supple of gas or steam and into can close automatically of design.
The technological scheme that the utility model is taked is that threeway, self-locking device are arranged, and threeway one outlet is connected with air bag, and another outlet is provided with air valve, and air valve is provided with guide rod, and guide rod links to each other with lever, and lever links to each other with self-locking device; Air bag is provided with extension spring, and extension spring links to each other with pull bar, and pull bar links to each other with self-locking device again.
Because the utility model has been taked technique scheme, utilizes the mechanical transmission of himself to come one control air valve to close, compared with prior art, have the energy of saving, easy to use, safe, advantage of simple structure.
Below in conjunction with accompanying drawing and example, structure characteristic of the present utility model is described further.
Referring to Fig. 1, threeway 1, self-locking device 2 are arranged on the utility model, threeway outlet 3 is connected with air bag 4, and threeway outlet 5 is connected with air valve 6, and air valve 6 is Normally closed types, air valve 6 is provided with guide rod 7, guide rod 7 links to each other with lever 8, and lever 8 links to each other with self-locking device 2 again, and air bag 4 is provided with extension spring 9, extension spring 9 links to each other with pull bar 10, and pull bar 10 links to each other with self-locking device 2 again.When pipeline was stopped the supple of gas or steam, air bag 4 shrank, and pull bar 10 forces self-locking device 2 to throw off lever 8 under the effect of extension spring 9, and guide rod 7 ejects, and air valve 6 is closed; During use, button 11 promotes lever 8, and air valve guide rod 7 is opened air valve 6, normal air feed.
