Abstract
The utility model discloses a gas mechanical-timing switch comprising a timer, a gas inlet pipe and a gas outlet pipe. The gas mechanical-timing switch also comprises a valve rod 7 arranged in a valve body 6, a spring 4, a rubber sealing ring 5, a rubber leakage proof plunger 9 and an oil slinger 8 connected with the valve body, and the timer 1 and the spring 4 can act on the valve rod 7 to control the switching of the gas. The gas mechanical-timing switch can be used to match with various gas ranges.
Description
The utility model relates to the combustion gas machinery time switch of a kind of and various gas cooker adapteds.
Existing household gas utensils switch valve all is manually-operable, does not introduce timing automatic and closes technology, and this brings inconvenience for people's daily life.For example: gas cooker is in use owing to people's carelessness or have no time to attend to or the soup that boils overflows and causes fire and extinguish the excessive contingency that takes place of combustion gas and happen occasionally, and this can cause economic loss and spiritual anxiety to people undoubtedly.Though the disclosed combustion gas timing automatic of CN2065735U gas-cutting off device has solved the problems referred to above to a certain extent, its complex structure, the cost height is difficult to popularize.
The purpose of this utility model is to provide a kind of combustion gas simple in structure machinery time switch.
The purpose of this utility model is to realize like this, that is: this combustion gas machinery time switch, comprise timer and into and out of tracheae, its key be one be contained in valve rod in the valve body, spring, rubber seal, the sliding plug of rubber leakproof and with the joining holder oil ring of valve body, timer and spring action are in the break-make of valve rod with the control combustion gas.
Be contained on all kinds of household gas ranges according to the above-mentioned combustion gas machinery time switch that assembles, when the knob timer is transferred to " often opening " position, at this moment timer just simultaneously pushes up up valve rod and rubber seal, spring is compressed, be on state into and out of tracheae, just gas cooker can be lighted, then by required period of combustion, timer is transferred to correct position, timer work is to the end of this section period, when timer knob returns back to the home position, valve rod and rubber seal just reset under the restoring force effect of spring, the blocking-up gas circuit.
In a single day the utility model compared with prior art can prevent when using gas cooker effectively, because of having no time to attend to or forgetting the accident that burnt gas switch causes of closing; Can carry out timing controlled to all kinds of gas range; Mechanical transmission is all adopted in this switch motion in addition, does not produce spark, and is safe and reliable, and long service life is easy to install.
Accompanying drawing is the utility model general structure schematic representation.
Below with reference to accompanying drawing concrete structure of the present utility model is further described.
Referring to accompanying drawing, the utility model combustion gas machinery time switch, comprise timer 1, into and out of tracheae 2,3, it is characterized in that: the sliding plug 9 of suction tude 2, spring 4, rubber seal 5 and rubber leakproof is housed successively from top to bottom at valve body 6 inner chambers, at rubber seal and the sliding plug of rubber leakproof endoporus, expanded joint has a valve rod 7, valve rod 7 one ends withstand on spring 4 ends, the other end withstands on the push rod of timer 1, steam outlet pipe 3 is vertical mutually with suction tude 2, all communicates with valve body 6 inner chambers, and holder oil ring 8 is enclosed within on the valve body lower portion boss.
The utility model is when work, need turn timer 1, make the push rod of timer promote valve rod 7 risings, with valve rod mutually the rubber seal 5 of expanded joint rise synchronously, thereby inlet, outlet 2,3 is conducted, realize the air feed burning, when fix time termination, it is downward that the restoring force of spring 4 just promotes the rubber seal of valve rod and phase expanded joint, blocking-up gas circuit, auto extinguishing.
