Description
Technical field
The present invention relates to valve technology field, more specifically a kind of gas furnace special regular is closed valve and filled safely
Put.
Background technology
Commercially burnt gas valve is varied, a feast for the eyes, and countlessly more, whoever can not know which kind of valve can
Reach safe and reliable performance, but accidents happened for combustion gas, is all because burnt gas valve poor sealing, leakage triggers the peace such as fire
Full accident.
Such as a kind of burnt gas valve disclosed in utility model patent CN201120152748.5, including valve body and handle, valve
Valve element and valve rod are provided with vivo, one end of valve rod is connected with valve element, and locating rod, one end of locating rod are provided between valve rod and handle
Circumferentially fixed between the other end of valve rod, the other end of locating rod is connected with handle, is provided between locating rod and valve body and works as valve
The location structure that locating rod can be circumferentially located in when door is in cut-off or opening on valve body.The function of most of valves is all
More similar to the valve in aforementioned patent, all relatively simple, defect is to be required for Attended mode, is so made in many situations
With can be restricted, such as during boiling water, people is busy leave after, hold it is bad return time, be easy for that fire incident occurs.Separately
Outside, fluid leakage is frequently experienced in the hole gap location of valve element break-through valve body.
For the above situation, a kind of combustion gas special regular closed safe valve of the applicant's innovative design, and equally obtain
Utility model patent, Patent No. CN201220198757.2, including a box body are obtained, an anti-leakage valve is provided with box body,
Anti-leakage valve includes a valve body, and valve pocket and the air inlet being conducted with valve pocket and gas outlet are provided with valve body；In valve pocket
The valve element being engaged with one of air inlet and gas outlet is provided with, valve rod is connected with after valve element, pressure is arranged with valve rod
Power spring；The free end that valve rod is stretched out outside valve body is connected with a clutch hook, and the corresponding position of clutch hook is provided with one to be coordinated with it
Drag hook, the rear end of drag hook is connected with a declutcher control lever, a pull bar is hinged with declutcher control lever, and pull bar is connected to electromagnet trigger
On；Electromagnet trigger is connected with time switch, and time switch is connected with reducing transformer.
The innovation advantage is to be arranged funnel-form sealing shroud on valve rod, and funnel-form sealing shroud can cover whole breathing
Hole, it is isolated in outside the first valve pocket, high leakproofness, prevent leakage can be ensured.Coordinate machine-operated technology clutch hook and resistance again
Clocked flip-flop combines, and is finally reached timing and closes gas furnace valve, and can enough reaches valve of gas pipeline sealing property
Safety measure well.
But among original design, however it remains some defects：（1）It is only to lean cooperation envelope between valve element and via
Close, be not very reliable；（2）The trigger mechanism of valve rod sliding movement is fairly simple, does not say arduously, and operation also can be not in place；（3）
The closing organ of Single electromagnet trigger not enough insures；（4）It can only manually be triggered in the case of without electricity, it is hidden to there is safety
Suffer from.
The content of the invention
The defects of it is an object of the invention to overcome prior art valve function not enough to insure, there is provided it is a kind of safe and reliable,
Can regularly close, and can also have electricity or without electricity in the case of normal work gas furnace special regular close valve safety
Device.
In order to reach object above, the present invention is achieved by the following technical solutions：A kind of gas furnace special regular closes
Valve closing door safety device, including a box body, a valve body is provided with the box body, an air inlet and one are provided with the valve body
