Abstract
Disclosed is a safe valve for pipeline gas which comprises a valve body. A ceramic valve core is arranged in the middle of the valve body; a torsion spring clamping tenon and a knob arranged on the upper end of the torsion spring clamping tenon are respectively fixedly assembled on a shaft of the ceramic valve core; a torsion spring is arranged at the outer side of a shaft of the torsion spring clamping tenon; an upper cover is arranged between the torsion spring and the knob; an electromagnet and a keeper hook adjacent to the electromagnet are also arranged on the upper part of the valve body; the keeper hook is connected with the torsion spring clamping tenon. The valve can be closed with the torsion of the energy storage torsion spring automatically or manually, the utility model has the advantages of fine sealing performance, long service life, convenient use and safety and reliability, which can solves the defects of the prior art effectively.
Description
Technical field
The utility model relates to a kind of combustion gas safety valve, especially a kind of pipeline gas safety valve.
Background technique
At present, the existing combustion gas safety valve that connects with fuel gas alarm is to adopt rubber product as Sealing mostly, and it is poor that this safety valve exists fireproof performance, easily aging defective; And adopt the cock-type safety valve of full-metallic sealing, when being failure to actuate for a long time, it is stuck to be prone to cock, thereby when causing running into combustion gas and revealing, can't cut off source of the gas.These all are the defectives that exists in the prior art.
Summary of the invention
The purpose of this utility model provides a kind of torsion of energy storage torsion spring that utilizes and makes valve closing, can close automatically also can manual-lock, good seal performance, long, easy to use and safe and reliable a kind of pipeline gas safety valve of life-span can effectively solve the defective that exists in the prior art.
The purpose of this utility model is achieved through the following technical solutions, a kind of pipeline gas safety valve, it comprises valve body, it is characterized in that: ceramic valve core is installed in the middle of valve body, fixed cover is equipped with torsion spring tenon and the knob that is positioned at torsion spring tenon upper end respectively on the axle of ceramic valve core, in the axle outside of torsion spring tenon torsion spring is installed, and between torsion spring and knob loam cake is installed, electromagnet and adjacent with it armature hook also are installed on valve body top, and the armature hook is connected with the torsion spring tenon.Position at the corresponding armature hook of valve body also is provided with a button.
The utility model replaces existing rubber seal or metal seal owing to adopt technique scheme by adopting ceramic seal spare, therefore has the characteristics of good seal performance, long service life; By adopting magnet control ceramic valve core switch, have characteristics esy to use, safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a switch motion schematic representation of the present utility model.In the accompanying drawing, 1-valve body, 2-torsion spring tenon, 3-torsion spring, 4-knob, 5-screw, 6-loam cake, 7-ceramic valve core, 8-button, 9-armature hook, 10-electromagnet, 11 limited posts.
Embodiment
The utility model comprises valve body 1, ceramic valve core 7 is installed in the middle of valve body 1, fixed cover is equipped with torsion spring tenon 2 and the knob 4 that is positioned at torsion spring tenon 2 upper ends respectively on the axle of ceramic valve core 7, the axle outside at torsion spring tenon 2 is equipped with torsion spring 3, between torsion spring 3 and knob 4, loam cake 6 is installed, electromagnet 10 and adjacent with it armature hook 9 also is installed on valve body 1 top, and armature hook 9 is connected with torsion spring tenon 2.Position at valve body 1 corresponding armature hook 9 also is provided with a button 8.When combustion gas takes place to reveal, after the fuel gas alarm that connects with safety valve is surveyed, send sound, light warning, send a pulse signal simultaneously, make the electromagnet 10 on the safety valve inhale moving armature hook 9 disengaging torsion spring tenons 2, torsion spring tenon 2 together rotates 90 ° thereby rotate 90 ° of axles that drive ceramic valve cores 7 in the counterclockwise direction with knob 4 under the effect of torsion spring 3, reach the position that limited post 11 is closed, and remain closed condition.After accident is removed, with hand knob 4 edges are clockwise rotated 90 ° of positions, armature hook 9 hooks the torsion spring tenon 2 of energy storage automatically at this moment, moves during wait warning next time; This valve also can pass through the manual-lock source of the gas, when the user wants to cut off source of the gas, only need press button 8, and button 8 promotes the purpose that armature hook 9 (be equivalent to electromagnet 10 suction moving armatures and link up with 9 o'clock action) realizes closing source of the gas.The utlity model has good seal performance, long, easy to use and safe and reliable characteristics of life-span.
