Description
Technical field
The present invention relates to kitchen range field, especially a kind of stopcock structure.
Background technique
Plug valve is widely used in gas cooker, but traditional plug valve is all existed due to outer ring tracheae and center tracheae
In same level, but the centre porosity of spool and outer ring stomata again cannot be in same levels, and which results in productions
Adding man-hour requirement according to centre porosity, tiltedly punching is connected to outer ring tracheae on spool chamber with the position of outer ring stomata, this operation does not have
There is a positioning, worker is easy to train off in production and processing, each and every one position disunity, some air inlet positions from spool chamber closely hold very much
Gas leakage is easily caused, brings security risk to user；The case where present kitchen range often will appear detonation in sparking and plug valve leakage
The case where gas and knob leakage fire, these are all that great security risk is brought to user.
Summary of the invention
In the detection find valve chamber gas outlet it is closer apart from valve chamber air inlet position, corresponding spool stomata to spool into
The height of gas end position is smaller, and the relatively smaller contact area made between spool and spool chamber of area is just smaller, causes to seal
It is bad, it be easy to cause gas leakage；User occur when using kitchen range detonation be due to igniting when, combustion gas prior to electric arc reach burner
Surface makes combustion gas surface have a large amount of combustion gas, reaches moment a large amount of combustion gas in electric arc while burning just will appear detonation and show
As from this, it will be seen that the valve body of plug valve opens the power connecting sheet contact plug-in piece prior to valve rod, is opened and is ventilated due to solenoid valve
Generating electric arc with power connecting sheet contact plug-in piece is generated after depressed stem, and depressed stem drives mandril to drive interlocking bar rotation
Then solenoid valve is opened, while the power connecting sheet on valve rod touches energization generation electric arc after plug-in piece, since solenoid valve is connected to early
It is generated in electric arc, depressed stem is formed to divide and is gone it can be seen that connecing electric forming than ventilating in electric stroke and ventilation stroke is connect
Journey is long, as long as it is longer than connecing electric stroke to form ventilation, then detonation can be solved the problems, such as；In addition kitchen range are when in use
Be easy to cause at knob leakage fire and be because combustion gas has certain air pressure, after ventilation combustion gas mandril can be jacked up and from spool and
Gas leakage between mandril will solve the power that this problem need to only be pushed to mandril, and preventing mandril from being jacked up can avoid gas leakage leakage fire.
The purpose of the invention is to overcome the shortcoming in the prior art, a kind of stopcock structure is provided, it is intended to solve
Certainly the problem of plug valve gas leakage, leakage fire and detonation.
In order to achieve the above object, the present invention uses following scheme:
A kind of stopcock structure, including valve seat, valve rod, spool are provided with spool chamber on the valve seat, and the spool is set to institute

Mouth and the second gas outlet, first tracheae are provided with lateral inclined tube, length extension of first gas outlet in inclined tube
On, second gas outlet is on the length extension of the second tracheae, and the bottom end setting of the valve rod is fluted, in the spool
On be provided with mandril, the ejector rod part protrudes from spool and protrudes into the groove and touch with groove groove face, sets on the spool
It is equipped with the second centre porosity and outer ring stomata, second centre porosity is consistent with the length of outer ring stomata in the horizontal plane.
In one or more embodiments, first tracheae includes inclined tube and escape pipe, the escape pipe and the second gas
Pipe is horizontally disposed, and the inclined tube connection escape pipe and spool chamber, second tracheae are connected to spool chamber.
In one or more embodiments, second tracheae is gone back on spool chamber level height middle line, the spool
It is provided with the first centre porosity, the second position of trachea of position of first centre porosity and the second centre porosity is corresponding, this
One centre porosity and the second centre porosity are located in spool same level on different location.
In one or more embodiments, the outer ring stomata is located at the lower section of the first centre porosity, first center
Stomata is small sircle hole, and second centre porosity is big hole.
In one or more embodiments, it is additionally provided with interlocking bar and solenoid valve, is arranged on the bar of the interlocking bar
There are switch block and hooked scarf, the switch block is located at below mandril, and before the hooked scarf is located at solenoid valve, the top rod driving switch block makes
Interlocking bar and hooked scarf rotation, the hooked scarf rotate and push solenoid closure.
In one or more embodiments, it is provided with connection sheet between the valve rod and valve seat, in the connection sheet and valve
Elastic slice is provided between bar, the elastic slice is to valve rod with downward elastic force.
In one or more embodiments, first gas outlet is provided with spacing apart from spool chamber inlet end.
The utility model has the advantages that the present invention provides a kind of stopcock structure, by changing plug valve outer ring tracheae and center tracheae
Position and make the first gas outlet of spool outside on cricotracheal length extension, the second gas outlet is in center tracheae
On length extension, cooperate corresponding spool, realizes spool production standardization, it is rapid, increase the first gas outlet apart from valve
The distance of core cavity air inlet avoids gas leakage, while the outer ring stomata of spool and the second centre porosity are in water to improve sealing
Hole is wide in plane unanimously realizes kitchen range outer ring fire and central flame when adjusting firepower while increasing or reducing simultaneously, in valve rod
Stroke of the upper setting groove to reduce mandril kitchen range first generate electricity to ventilate afterwards, combustion gas once in the case where strike sparks,
Speed of ignition is improved, realizes and lights a fire at once while electric arc occurs.
