As Fig. 2, Fig. 3 and shown in Figure 4, the preferred embodiment of the utility model segmented gas switch valve, be in a body 40, to be provided with the main airway 41 of an air inlet and the branch airway 42 of an exhaust, this body 40 also is provided with an inferior longitudinally tracheae 43 in

main airway

41 and 42 of branch airway, and provide once air flue 44 in the inferior tracheae 43, this time air flue 44 inwall stage casings are equipped with a flange 441, and be communicated with a passage of tiltedly establishing 45, can be by this main airway 41, passage 45, inferior air flue 44 and branch airway 42 be interconnected and become one can be for irritating, the gas passage that exhaust is used, and a press device 50 is established in inferior tracheae 43 tops.Because the above-mentioned traditional technology that is all is so narrate no longer in detail at this.And main improvement emphasis of the present utility model will be described below.

This time tracheae 43 hypomeres one side is provided with a screw 431, screw 431 tops are carved and are provided with a location mark 432, a capping 46 is established to seal the opening of time air flue 44 belows in its bottom, revolves a control device 60 and an interlocking device 70 and also be provided with one in inferior tracheae 43 Lower Halves.

This revolves control device 60 and includes a nut 61, an operating bar 62, a moving block 63 and a knob 64.This nut 61, its bottom is provided with an open-work 611 along axial direction, and external annulus is provided with an outside thread 612 and can be fixed on time tracheae 43 screws 431; This operating bar 62 has a shoulder 621 and outer wall is provided with two drop-stopping rings 622 for preceding half section, can plug and support and terminate on nut 61 open-works 611, its Hou has a polygon shell of column 623 and extends to time air flue 44 inside for half section, and the Hou end respectively is provided with a screw 624,625 along axial direction before this operating bar 62; This moving block 63, for plastic cement penetrates one-body molded, has a polygon post hole 631 that provides, and be placed through on these operating bar 62 polygon shell of columns 623, these moving block 63 outer circumferential faces are arranged with the pushing tow projection 632,633,634 and 635 of four different heights along polygon post hole 631 axial rings, and this moving block 63 is a bolt 65 location of being located at operating bar 62 Hous end screw 624 with spiral shell; This knob 64 is to be fixed at operating bar 62 front end screws 625 and to be located at time tracheae 43 outsides by a screw rod 66, and these knob 64 outer side surfaces are in being provided with relative cue mark 641 to should moving block 63 each pushing tow bump position carving.

This interlocking device 70 has a blocking element 71 and an elastic element 72, this blocking element 71, be to be made into integration discoid piston body with the rubber material, and it is corresponding with this flange 441, its first half ring side convexes with three limiting stoppers 711, make blocking element 71 more firm when moving up and down in inferior air flue 44, blocking element 71 Lower Halves are tool one pole 712 then; This elastic element 72 is a spring, and its top and this pole 712 set firmly, and its bottom is then supported and terminated in this moving block 63 tops.

The assembling mode of segmented gas switch of the present utility model, be earlier this moving block 63 to be placed through on these operating bar 62 polygon shell of columns 623, and be located at operating bar 62 Hous with these bolt 65 spiral shells and hold screw 624, make moving block 63 location, these operating bar 62 plugs are established to terminating on nut 61 open-works 611, with screw rod 66 this knob 64 is fixed on the operating bar 62 front end screws 625 again, just can finishes the assembling of revolving control device 60.

Then, with elastic element 72 and blocking element 71 fixed Hous, place in time air flue 44, to assemble the control device of finishing 60 that revolves again in advance wears and is fixed on time tracheae 43 screws 431, and make this elastic element 72 of moving block 63 top contacts, Hou is fixedly arranged on this capping 46 on time tracheae 43 bottoms, i.e. assembling is finished.

The statement of effect that the action of each member of the utility model and institute's expectability are reached as after.

At first, with regard to gas flow control, when this knob of rotation 64 drives operating bars 62 and this moving block 63 and together rotates, this elastic element 72 of top on the pushing tow projection on this moving block 63, make this blocking element 71 cover this passage 45, this blocking element 71 is influenced by the pushing tow projection of different heights, and is in the different height and position of this passage 45, and, adjust the size of control gaseous flow by the indication of knob 64 outside cue marks 641.As shown in Figure 4, make on the pushing tow projection 632 on the moving block 63 this elastic element 72 of top, make this blocking element 71 only cover the little part of this passage 45, and have big flow space, the occasion that needs the big fire larynx such as be fit to use in the dining room.As shown in Figure 5, make this elastic element 72 of top on the pushing tow projection 635 on the moving block 63, cause this blocking element 71 to cover this passage 45 major parts, and have the small flow space, the convenient occasion of little fiery larynx that generally needs is used.Again with regard to blocking-up gas leakage effect, as shown in Figure 6, when gas leakage takes place in coal gas, the ambient pressure bust, cause body 40 internal pressures bigger, make blocking element 71 bottoms be subjected to the ejection of internal high pressure gas and move up and push up and fill on this flange 441, and reach the purpose of blocking coal gas gas leakage fully, only need during recovery pressing down by press button 51 of press device 50 got final product.

Just can be for replenishing with regard to the aeration, as shown in Figure 7, when coal gas when branch airway 42 places begin to carry out aeration, this blocking element 71 is subjected to the gas strength of pushing and pressing downwards, and press down this elastic element 72, make time air flue 44 have bigger flow space, and can reach the effect of quick aeration.

In addition, as shown in Figure 8, be another embodiment of the utility model, be provided with the inferior air flue 83 that a main airway 81, a branch airway 82 and provide in a body 80, this branch airway 82 is arranged with a stopping leak ring 84 with time air flue 83 connecting parts.Inferior air flue 83 epimeres are provided with this press device 50, and its hypomere then is provided with this and revolves control device 60 and this interlocking device 70.These blocking element 71 top overheads have an inaccessible pearl body 73, and this revolves control device 60 and drives these obturation pearl bodies 73 indirectly and move up and down when producing class's drop when regulation and control, can adjust the output flow of source of the gas, as shown in Figure 8, are the schematic representation of flow when big.

As shown in Figure 9, should obturation pearl body 73 when leaking gas supported by the propelling movement of internal gas and terminate on this stopping leak ring 84, form closely to paste and touch and block that body 80 is inner continues gas leakage for coal gas.

As shown in figure 10, the utility model is applied to be provided with a main airway 91 and a branch airway 92 in the valve body 90 on the super flow safety governor of a kind of coal gas, vertically provides air flue 93 one time in main airway 91 and 92 of branch airway.A flange 931 is established in this time air flue 93 inwall middle sections, this press device 50 is established in its top, the below is then established this and is revolved control device 60 and this interlocking device 70, because the super flow safety governor of this coal gas does not have the effect of aeration, so 70 of this interlocking devices are provided with this blocking element 71, and directly be subjected to this to revolve control device 60 and drive, but still have the effect of adjusting flow size and blocking-up gas leakage.
