Description
(1) technical field
The utility model relates to a kind of valve, and especially the gas furnace with mechanical timer control regularly closes the gas easing valve.
(2) background technology
Along with the development of modern society, combustion gas such as oil liquefied gas, coal gas are used in the city in a large number.Though it brings many facilities for band people life, also has many fatal hidden danger simultaneously.As heat up water with gas furnace, during fricassee, if water has been opened, food stew cooked after, forget instant pass gas, easily cause various accidents.
Existing gas furnace can only be adjusted the size of air inflow and control firepower, can control the cooking time automatically unlike electrical equipment such as electric oven, micro-wave ovens.Existing mechanical timer has a wide range of applications, and for example generally is used for the mechanical timer of electric fan, can divide 45min by its length of fixing time, 60min, and 120min etc. are to realize timing cutting power by predetermined means, and electric fan is shut down.
(3) summary of the invention
The purpose of this utility model is to provide a kind of and can be used on the various gas furnaces, makes gas furnace energy self-timing close the easing valve of gas.
The utility model is provided with mechanical timer and self-closing valve.Mechanical timer comprises shell, mechanism and contact switch when walking.Mechanism is similar to simple mechanical clock when walking, and is made up of power set, gear drive and escapement pendulous device three parts.Power set are made up of turning handle, clockwork spring, great wheel, stage clip etc.Clockwork spring is the element of energy storage, is the power of mechanism when walking, and clockwork spring one end is located on the mainspring hook of great wheel axle, and the other end is located on the clockwork spring post.Great wheel is toothed circular gear, and stage clip is fastened on the great wheel axle, and they can rotate around the great wheel axle, can turn round with clockwork spring again, give gear drive transmission of power.Can slide between stage clip and the great wheel, be convenient to counterclockwise rotate in case of necessity, stage clip slides on great wheel, loosens clockwork spring.
Gear driving device by great wheel, two take turns, three-wheel, four-wheel form.They all are the gears of tape spool, wherein two take turns, three-wheel, four-wheel all be to be made of the in-line gears that two diameter do not wait, the major diameter tooth of last gear meshes successively with the minor diameter tooth of back one gear, form 4 grades of mechanisms of driving up, make turning handle rotation less than all traveltime apparatus 60min that can turn round.
The escapement pendulous device is made up of escape wheel, bolt and escapement.The four-wheel engagement of escape wheel and gear driving device, the power that four-wheel is passed to it passes to escapement by the bolt that is attached thereto, and makes the escapement swing.Bolt had both obtained the power that escape wheel transmits, and limited the speed that escape wheel transmits again.So turning handle turns over a less angle, its timing can be quite long.
Self-closing valve is located at the timer below, and it comprises push rod, loam cake, loam cake seal dissepiment, valve body, turnover tracheae, piston, stage clip and bottom.Active force lower piston at stage clip is in the state of closing at ordinary times, makes gas can't pass through pore, reaches the function of automatic pass gas.Loam cake and timer fixed support are connected as a single entity, loam cake and loam cake seal dissepiment are fixed on the valve body, the projection lower end of the last termination timer of push rod, push rod is connected with piston rod, the upper end of stage clip is positioned at piston packing and piston seal ring support below, the lower end of stage clip is spun on the valve body with the bottom bolt, and band bottom sealing ring.Air inlet pipe fuses with escape pipe mutually and with valve body through piston hole.
The utility model has increased insurance together to the safe handling of various gas furnaces, and it is simple in structure, easy to manufacture, with low cost, dependable performance, simple installation.Need only extract former stove air induction hose, it is inserted on the air inlet pipe, the flexible pipe of giving vent to anger is inserted on the former cooking stove get final product again.If need to adopt regularly, need only turning knob, forward on the predetermined scale, the food boiling is intact promptly dies automatically.Can directly be transferred to ON during without timer and often open on the position, need not be set to for a long time on the OFF Chang Guanwei, use particularly safe and simple.

(5) specific embodiment
Following examples will be further described the utility model in conjunction with the accompanying drawings.
Shown in Fig. 1～4, the utility model comprises shell 29, timer 1 and self-closing valve.Self-closing valve comprises push rod 19, loam cake 4, loam cake seal dissepiment 5, air inlet pipe 7, escape pipe 16, valve body 8, piston rod 14, piston packing 18, piston seal ring support 17, stage clip 9, bottom bolt 11, bottom sealing ring 27.Timer fixed support 23 is to be connected as a single entity with loam cake 4, timer 1 is to be fixed on the timer fixed support 23 with timer hold-down screw 3, loam cake 4 and 4 loam cake screws 20 of loam cake seal dissepiment 5 usefulness are fixed on the valve body 8, wherein push rod 19 is to be connected with a SMIS screw with piston rod 14, therebetween loam cake seal dissepiment 5 seals, but and utilizes the elasticity easy on and off activity of rubber.Piston hole 12 by piston seal ring support 17 and piston packing 18, is blocked piston hole 12 under the pressure effect of stage clip 9, the other end of stage clip is to utilize the screw thread 10 on the bottom bolt 11 to be spun on the valve body, and be added with bottom sealing ring 27 prevent gas leakage.Gas can't pass through piston hole at ordinary times, has only when knob 26 is screwed into ON and often opens position 30 or be screwed into regularly on the graduation apparatus 32, and the cam in this moment timer 1 ejects projection 22, and promotes push rod 19, piston rod 14 and piston packing 18 and move down, and piston hole 12 is opened.Because piston rod 14 is provided with air channel 6, make gas arrive escape pipe 16 from the air inlet pipe 7 smooth and easy piston holes 12 that flow through.In addition, projection 22 is to be fixed on the shell of timer by projection fixed axis 21 in the timer, when timer travel arrives OFF Chang Guanwei 31, projection just slips in the groove of cam 24, and simultaneously, the other end on the projection 22 just withstands on the timer escapement 2, timer is stopped, piston is blocked piston hole again again under the pressure of stage clip at this moment, closes gas circuit.
Referring to Fig. 4, the external flexible pipe 28 of giving vent to anger can directly be inserted on the cooking stove, and former cooking stove air inlet pipe can change and is inserted on the air inlet pipe 7.In addition, can be provided with permanent magnet at the timing valve bonnet, double-sided adhesive or screw hanging hole can directly be adsorbed on the cooking stove wall easing valve, or are bonded on wall or the cabinet wall with double-sided adhesive, or be screwed.
