Description

Kitchen gas safe value

The utility model relates to a kind of valve gear, particularly relates to a kind of kitchen gas safe value.

At present, commercially available kitchen gas safe value has three kinds, and first kind is the safety valves for gas that only has depressurization; Second kind is the high-pressure gas safety valve that high-pressure gas is used; The third is to have decompression and safety valve that can automatic self-closing gas when the accident dangerous situation occurring.These three kinds of safety valves all have shortcoming, and the shortcoming of first and second kind is can not automatic self-closing gas when having an accident dangerous situation, and generation causes the accident; The third shortcoming is to set the cooking time according to user's needs, closes combustion gas if the user forgets, also can have an accident.

The purpose of this utility model is to provide a kind of multi-functional kitchen gas safe value, it can not only set the cooking time according to user's needs, and can be when the accident dangerous situation takes place automatic self-closing gas, avoid accident to take place, can also regulate the kitchen gas safe value that becomes high-pressure gas.

The purpose of this utility model is by providing a kind of kitchen combustion safety valve with following structure to realize, this kitchen gas safe value comprises: housing, air gauge, the garden ball valve, garden ball valve push rod, little fluid sealant, the lever adjusting rod, lever is regulated and is dialled the wooden fork pull bar, the pressure regulation rubber film, regulating spring, set screw, valve seat, spool, timer arrangement, described housing has the inlet channel that is interconnected, low-pressure chamber, be conditioned outlet passageway and air chamber that rubber film separates, described inlet channel and low-pressure chamber junction have a little air inlet, the air inlet top is opened and is used to install garden ball valve and garden ball valve push rod flatly, installing the back blocks with rubber stopper, garden ball valve and garden ball valve push rod are connectors, garden ball valve push rod penetrates from air inlet and extends low-pressure chamber, the garden ball valve drops on the O-ring seal on the air inlet, the appropriate location dress air gauge of described inlet channel, described timer arrangement is that commercially available Mainspring type electric fan timer device repacking is obtained, done a groove at timer arrangement master gear endoporus, do a protruding tooth at its rotary main shaft and its master gear endoporus intersection, protruding tooth matches with groove, make the rotary main shaft can be up and down, the clockwork spring turn that can drive again on the master gear makes the timer operate as normal.The top dress handle of rotary main shaft, the other end extends in the low-pressure chamber, and spool is fixed on this end, and cam, cam chamber, the recessed wheel are arranged in the described timer arrangement, the recessed wheel done one and often opened stuck point, and cam is installed on appropriate location, rotary main shaft middle part makes it in the cam chamber.

Compared with the prior art the utility model kitchen gas safe value has following advantage: because the garden ball valve has been installed, timer arrangement, set screw, regulating spring, make that it can regularly be closed, the effect of automatic self-closing gas, avoid accident to take place, can become high-pressure gas by adjusting again.

Below in conjunction with accompanying drawing embodiment of the present utility model is described.

Fig. 1 is the cutaway view of the utility model spool when being positioned at open position;

Fig. 2 is the cutaway view of the utility model spool when being positioned at the closed position;

Fig. 3 is the utility model timer arrangement fovea superior wheel vertical view;

Fig. 4 is a master gear internal view on the utility model timer arrangement.

Fig. 1, Fig. 2 shows the embodiment of the utility model kitchen gas safe value, housing 1 has the inlet channel 2 that is interconnected, air inlet 6, low-pressure chamber 13, outlet passageway 17 and valve seat 16, air chamber 14, inlet channel 2 upper wall appropriate locations dress air gauge 18, garden ball valve 3 is a disjunctor with garden ball valve push rod 5, making garden ball valve push rod 5 pass air inlet 6 extends in the low-pressure chamber 14, garden ball valve 3 drops on the O-ring seal 4, screw hole 29 is arranged at air chamber 14 bottoms, set screw 12 is contained in 29 li of screw holes, regulating spring 11 1 ends are enclosed within on the set screw 12 that puts in air chamber 14, the other end is dialled wooden fork pull bar 10 with pressure regulation and is connected, regulating rubber film 9 usefulness screws 31 is contained between low-pressure chamber 13 and the air chamber 14, the sealing plug 7 of lever adjusting rod 8 one ends dress is aimed at garden ball valve push rod 5, the other end is installed in pressure regulation and dials on the wooden fork pull bar 10, with reference to Fig. 3, Fig. 4, timer arrangement 30 comprises handle 26, little spring 27, rotary main shaft 25, protruding tooth 24, master gear 23, recessedly take turns 22, cam chamber 20, cam 21, timer arrangement 30 usefulness Screws 19 are installed on the appropriate location of housing 1, doing a groove 32 in the master gear 23 matches with protruding tooth 24 on the rotary main shaft 25, recessedly take turns 22 1 and do one and often open stuck point 28, rotary main shaft 25 passes valve seat 16 and extends in the low chamber 13, its this end cartridge spool 15, other end dress handle 26.

When the needs cooking food, open the combustion gas master switch, handle 26 is pressed, and makes spool 15 head on pressure regulation and dials wooden fork pull bar 10, sealing plug 7 jack-up garden ball valve push rods 5 on it make garden ball valve 3 leave sealing ring 4 and combustion gas are entered in the low-pressure chamber 14 smoothly, can become high-pressure gas by set screw 29.
