Set forth operation logic of the present utility model below in conjunction with accompanying drawing, and provide embodiment of the present utility model.
Retaining in the left and right hydroecium (III) in the carbonated drink separator box V, (11) flow to the boiler chamber when being evaporated to limiting water level automatically from the admission port, the controlled fabrication of ball float link rod (4) (6) lock-bit of its right ventricle (II) can not fall the ball float (9) of being located at ball float link rod (4) end with the decline of water level; But along with the decline of left and right hydroecium water level, the ball float of being located in the left hydroecium (I) (9) then begins to fall with water level.Because the whereabouts of this ball float, left ball float link rod (4) is rotated around fulcrum, thereby the sliding shaft sleeve (16) that link rod the right is connected with this link rod (4) is pushed to peak, the push rod of being located at this moment on this sliding shaft sleeve (16) (18) is thrown off, right ventricle's ball float link rod (4) that former controlled fabrication (6) is blocked, break away from the control of control card (6), fall rapidly, fall on the qualification water level face of right hydroecium in right ball float (4) deadweight effect; In this displacement process, the valve shaft (15) of the control water column valve F that originally connects with right hydroecium ball float link rod (4) afterbody also rises thereupon.Because the rising of valve shaft (15) impels the apical axis (29) of its top and its decompression warning T bottom on same plumb line also upwards to push away.Owing to push away on this apical axis (29), make and be located at that the following conical valve (28) in the steam chest (30) pushes away simultaneously under the decompression alarm valve T, make the middle conical valve (26) of being located at the same valve shaft other end remove valve synchronously.At this moment the steam of carbonated drink separator box V promptly enters middle steam chest (33) by steam transmitting pipe (3), and again through the middle conical valve (26) opened by last top and in being located at down the air flue on the valve seat (27) enter down steam chest (30), the appendix (3) of steam chest (30) side enters in the outer steam heating tube of boiler body again under the warp again, flow to and use the gas place, make Boiler Steam in extracorporal circulatory system.
When carrying out the above-mentioned course of work, owing to move on the control water column valve F valve shaft (15), the water source that connects with this valve body lower valve port is poured into rapidly, and enter and its top joining carbonated drink seperating vale P along the inlet channel of being located at column valve body rear portion (39), because the last vapour lock (1) of carbonated drink seperating vale P communicates with the steam chamber in boiler chamber, make the part steam and the interior water meeting of carbonated drink seperating vale P of flowing through in the boiler, water promptly flows into the left hydroecium (I) of carbonated drink separator box V by faucet (19) under the acting in conjunction of steam, until with a left side, right hydroecium is annotated the standard high water level; Along with the rising of water level, amass in the part steam on carbonated drink separator box V top again through the air inlet pipe (8) of decompression alarm valve T, middle steam chest (33) steam chest (30), appendix (3) down, import in the steam pressurized pipe until using the vapour place.
Inject the process of carbonated drink separator box V by the faucet (19) of sluice (39), carbonated drink seperating vale F at water, at first flow into the water of left hydroecium (I), because the restriction of being located at the interior water-stop sheet (13) of casing and placing water-stop sheet limbers, below (12), can only flow into right hydroecium (II) to finite quantity, and add in the boiler cavity by the delivery port (11) of being located at right hydroecium (II) bottom from this limbers (12).Remaining most of water is filled with water with left hydroecium (I) in advance, and the water-stop sheet (13) that then overflow is again filled with right water and stopped up (II).The ball float (9) that be located in the left hydroecium (I) this moment is held up by water, and the ball float link rod (4) of this ball produces under buoyancy function and reverses clockwise; Because this reversing, the sliding shaft sleeve (16) that the link rod right-hand member is moved on originally is pressed down; In case when left chamber ball float (9) was floated to limiting altitude, this sliding shaft sleeve (16) also was reduced to lowest order.Be in left hydroecium (I) is filled with this moment, also is that water overflows in the into right hydroecium (II) from water-stop sheet (13), and right hydroecium (II) water level is risen gradually.The right ball float (9) that raises simultaneously along with the rising of right hydroecium (II) water level, make right ball float link rod (4) produce reversing counterclockwise around fulcrum, this twist motion also will move down with the valve shaft (15) of link rod termination joining control water column valve F, when its ball float link rod reaches horizontal level, also be that valve shaft (15) moves down in the sealing water inlet that resets; Right ball float link rod this moment (4) do not hold shaft deep-slotted chip breaker (17) effect down again cunning under control card (16), be in the lock state.Final interrupt the water source, outside continue enter, reach the regularly purpose of control amount water filling.
The contrary warning injector of pressing of non helping hand full-automatic boiler does not promptly have water filling work intermittently repeatedly by said procedure.
Its warning function realizes that under the state of cutting off the water supply its course of work is as follows:
Under the state of cutting off the water supply, the water of the left and right hydroecium of this carbonated drink separator box V is also vaporized by boiler evaporating gradually, and water level is sharply descended, and surpasses minimum warning line; This moment is because the ball float that right hydroecium (II) descends greatly reverses ball float link rod (4) generation, because this reversing makes the valve shaft (15) of control water column valve F hold the upwards operation of continuing property, and the apical axis (29) of the alarm valve T that at first will reduce pressure promotes up, to descend conical valve (28) to go up the top subsequently, middle conical valve (26) is backed down, also back down until going up conical valve (23) again through last conical valve (26), steam this moment steam chest (33) from decompression alarm valve T, the air flue of valve seat (35) in going up, last steam chest (36) enters the siren chamber, reaches at last to promote flute ball (21), reed spring (20) makes it to send the warning birdie.Can eliminate danger as long as cut off the burning things which may cause a fire disaster line or connect the water source this moment.
