Description
Technical field
The present invention relates to mechanical engineerings, and are specifically related to a kind of gas for cooking valve.
Background technology
Due to the corrosion between valve surface and valve shaft, existing gas for cooking valve usually has the problem of gas leakage.
After long-time use, valve surface is corroded and becomes uneven, and gas is caused to leak and waste.In addition, in the existing cooking
The import and export of gas trap, there is no settings to prevent what gas from flow out from gas tank inversely to go out to flow anti-locking mechanism.Even if working as hand
When dynamic rotating mechanism is opened, which is also possible to prevent gas leakage.In this case, because existing at gas inlet and outlet
The reverse flow of gas is blocked to prevent valve, so the gas of outflow will flow back.
Invention content
Gas for cooking valve according to the present invention includes hollow valve body, which has manual rotation disk on the top,
For opening and closing the gas of inflow gas tank.It is the shape of threads top for being fastened to valve body at the lower part of manual rotation disk
The external screw thread of inner surface.The lower central axis of manual rotation disk is used as the direction of rotation relative to manual rotation disk in the upper of valve body
The transmission shaft that portion's body interior moves up and down.There is transmission shaft elongated cylindrical main body, the diameter of its underpart to be more than top.Transmission shaft
Lower part at be multiple slots for receiving O-ring.It is disc below transmission shaft, the disc is relative in the movement of transmission shaft
Lower movement, for opening and closing the gas inlet and outlet of valve body.Disc has cylinder-shaped body, and lower end is inwardly slightly gradually
Contracting so that it can be appropriately mounted to the gas inlet and outlet of valve body.
Inversely the anti-locking mechanism of output flow includes hollow reception bearing, which has for being fastened to side groove
Internal thread shape of threads outer surface.It is the slot for receiving O-ring at the rear portion of reception bearing, to prevent the side groove of valve body
Inner surface and receive bearing between gas leak.The central core for receiving bearing is assembled to piston.
Piston is formed as single piece, and there is hollow cylindrical, diameter to correspond to the central core for receiving bearing for front end
The size in portion.The front end of piston has around multiple holes of front end, this some holes is used as gas in gas for cooking valve inside stream
The flow channel for entering and flowing out.The rear end of piston is the disk that diameter is more than front end, and around the outer surface of rear end
It is provided with and extends outwardly to receive multiple flanges of spring lever.Interface between the front end and rear end of piston is for connecing
The slot of washer is received, which is mounted in slot, is leaked to prevent from receiving the gas between bearing and piston.
The preceding inboard lip of the front end of piston is inserted into auxiliary O-ring, to prevent from preventing valve to be moved to it when reverse flow
In closed position when at the preceding inboard lip of piston gas leakage.Being reverse flow inside the front end of piston prevents valve, should
Reverse flow prevents valve to be formed as circular shape, for due to being moved in quite high-caliber gas pressure in gas tank
Closed position to the preceding inboard lip of the front end of piston.
The object of the present invention is to provide a kind of reverse output flow mechanisms for cooking gas trap, even if working as manual rotation mechanism
When either intentionally or unintentionally opening, which is also prevented from gas and is flowed out from gas tank.Because existing at gas inlet and outlet and blocking gas
The reverse flow of body prevents valve, so the gas of outflow will flow back.This can help to reduce since gas leaks caused danger
Possibility.In addition, also there is gas for cooking valve according to the present invention control valve system, the control valve system to be used for controlling
Gas discharge and prevent gas from flowing out past scheduled level.
