Abstract
The utility model relates to an electromagnetic type rapid and safe gas cut-off valve, the mechanism of which consists of a butterfly valve, a tractive electromagnet, a transmission rod, a lever device and a heavy hammer, wherein, one end of the transmission rod connected with the butterfly valve is connected with the lever device by a lock pin, the other end of the transmission rod is connected with the heavy hammer; the lever device comprises a lever bracket and a lever connected with the lever bracket; the middle part of the lever bracket corresponding to the lever is provided with the tractive electromagnet. The electromagnetic type rapid and safe gas cut-off valve of the utility model is high in gas sealing performance and is safe and reliable by automatic cutting off; besides, when in use, the cut-off valve is not required to be driven for cutting off gas, thus preventing hidden trouble of serious accidents due to incapability of the valve of cutting off gas in case of power off, and the cutting off speed is higher than that of an electric cut-off valve.
Description
Technical field
What this product related to is a kind of cut-off valve, Electromagnetic Fast Safety Gas Shut-off Valve specifically.
Technical background
In industrial applicability coal gas or air operation occasion; the electronic cut-off valve that is assembled in coal gas or the air conduit is very universal; played very big effect for preventing some major safety risks; but coal gas or air generation low pressure reason are a lot; wherein also comprise the coal gas or the air low pressure that have a power failure and cause; so the motorized motions cut-off valve of using just can't be worked; can not reach protective action; and cause the generation of accident, so need that design is a kind of not to need power-actuated safety cut-off valve.
The model utility content
Technical assignment of the present utility model is at above deficiency, and Electromagnetic Fast Safety Gas Shut-off Valve is provided, and the cut-out mode solves above-mentioned shortcoming by relying on oneself.
The technological scheme that its technical problem that solves the utility model adopts is: Electromagnetic Fast Safety Gas Shut-off Valve, its mechanism comprises butterfly valve, tractive magnet, drive link, leverage, weight, the described drive link that is connected with butterfly valve one end links to each other with leverage by lock pin, the other end links to each other with weight, described leverage comprises lever dolly, is connected the lever on the lever dolly, and the medium position of corresponding lever is provided with tractive magnet on lever dolly.
Described lever and lever dolly in the left side, middle part, right side be respectively with manually locking pin, moving fulcrum, extension spring interconnect.
The described butterfly valve outside is a valve body, and the middle part is a valve plate.
Also be provided with the tenminal block box between the described butterfly valve outside and the lever dolly.
Electromagnetic Fast Safety Gas Shut-off Valve of the present utility model has following beneficial effect:
Butterfly valve adopts teflin ring, and the tightness height is then by the cut-out of relying on oneself, safe and reliable, do not need motor driving to cut off coal gas when using, avoided when having a power failure cut-off valve to cut off and produce the hidden danger of major accident, cut-off velocity is also fast than electronic cut-off valve simultaneously.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is an Electromagnetic Fast Safety Gas Shut-off Valve agent structure schematic representation of the present utility model;
Fig. 2 is the right TV structure schematic representation of Electromagnetic Fast Safety Gas Shut-off Valve of the present utility model.
Embodiment
Explain below with reference to Figure of description Electromagnetic Fast Safety Gas Shut-off Valve of the present utility model being done.
Electromagnetic Fast Safety Gas Shut-off Valve of the present utility model, its mechanism comprises butterfly valve, tractive magnet 5, drive link 4, leverage, weight 1, the described drive link that is connected with butterfly valve 4 one ends link to each other with leverage by lock pin 3, the other end links to each other with weight 1, described leverage comprises lever dolly, is connected the lever 7 on the lever dolly, and the medium position of corresponding lever is provided with tractive magnet 5 on lever dolly.
Described lever 7 and lever dolly in the left side, middle part, right side be respectively with manually locking pin 2, moving fulcrum 6, extension spring 8 interconnect.
The described butterfly valve outside is a valve body 9, and the middle part is a valve plate 10.
Also be provided with tenminal block box 11 between the described butterfly valve outside and the lever dolly.
Just often, tractive magnet 5 gets electric, and its tractive force is enough to extension spring 8 and stretches, the breach of the lock pin 3 card upper levers 7 on the drive link 4, and this moment, valve plate 10 was in fully open position, normal supply coal gas or air.
When coal gas or combustion-supporting air pressure are lower than permitted value, when perhaps other medium parameters transfinite, flashing signal alarming controller or other control circuit that other are supporting make the electromagnet dead electricity, tractive force disappears, and extension spring 8 shrinks, and lever 7 raises up at the left end of fulcrum 6, the breach that lock pin 3 breaks away from the lever 7, weight 1 falls, and drive butterfly valve plate 10 is rotated counterclockwise and makes valve be in closed condition, has so just reached the purpose of cutting off coal gas.
When low-voltage accident handle each parameter normal after, manually open cutting-off valve.
Electromagnetic Fast Safety Gas Shut-off Valve of the present utility model has valve position beginning, dead space switch, shows valve position signal and control and remote manual control automatically by supporting WP-X803A type flashing signal alarming controller.
But Electromagnetic Fast Safety Gas Shut-off Valve level of the present utility model or vertical the installation.
