The purpose of this utility model is to make a kind of automatic hot-water heating exhaust apparatus, and it is simple in structure, and cost is low, and is easy to install, can discharge the air in the heat transmission gas automatically, and user's needs are satisfied in heat supply in time.

The utility model is mainly by upper shell, lower house, piston, thimble, needle guard, connection plug, wireway, fixed cover, noise reduction valve with slide post and form.Wherein the upper and lower casing cross section is square or the scarce type body of circle, as shown in Figure 2; Many through holes are arranged on the surface except the two ends upper and lower casing, and the air in the radiator fin group is discharged through needle guard, wireway, noise reduction valve after the hole enters upper and lower casing thus.The upper and lower shell body and function slides post and connects, and forms whole housing.There are two through holes the lower house bottom surface, slides post usefulness for inserting to wear.With the upper shell place of lower house corresponding position projection is arranged, is drilled with screwed hole, can with slide post and connect.Piston is a matrix, and left and right two parts are hollow bodies of sealing.In the middle of each hollow body a through hole is arranged, slide post and from then on pass through in the hole.Recess center fixation thimble in the middle of the piston, piston is inserted in the upper and lower casing.Thimble is sharp cone, matches with conical needle guard.Wireway is

Type circle tubule, its end was inserted the hole of locating in the middle of the upper shell, was fixed in the upper shell with nut; Connect plug and be inserted on this termination, needle guard inserts in this stomidium pipe again.The wireway other end is screwed in the fixed cover centre bore.Fixed cover is the circle prismatic, and an end is cylindrical, and outer surface has screw thread can be screwed into the blanking cover central hole of radiator fin; The other end is a prismatic, and centre bore is a screwed hole.Noise reduction valve is that cylinder and hollow ball shape are formed, and spherical tips has opening, fills full sponge in the hollow ball, can eliminate or weaken effectively the noise of air blast generation like this.The noise reduction valve cylindrical end is screwed in the fixed cover centre bore.Sliding post upper end cylinder has screw thread, and the lower end is a convex.Sliding post can be inserted by two holes, lower house bottom surface, through the corresponding duct of piston, is screwed in the screwed hole at upper shell convex place, so not only can connect upper and lower casing, can be used as the upper and lower mobile slideway of piston simultaneously.

Automatically the operation principle of hot-water heating exhaust apparatus is: when beginning to heat, along with entering of hot water in the radiator fin group, the volume of gas will reduce, pressure increases, be subjected to the weight of the buoyancy of gas owing to have the piston of thimble less than self, therefore the gas pressure intensity in the radiator fin group is higher than outside pressure, and gas is discharged from needle guard centre bore, wireway and noise reduction valve.At this moment the hot water in the radiator fin group will rise.Rising along with water level, piston in the housing is subjected to water buoyancy, and can constantly increase, the buoyancy that the match of living is subjected to floats greater than self gravitation, thereby the thimble of piston center is matched with the needle guard hole, along with the continuous rising of water level, thimble cooperates tighter with needle guard, few residual gas of result and hot water all can not be discharged, and save hot water, thereby improve and guarantee the thermal efficiency of radiator fin group.When in the heating cyclic process, there is new gas to be present in the radiator fin group again, the water level in the radiator fin will descend again, thimble and needle guard are broken away from, the result can make new gas go to outside the radiator fin again, and along with water level rises, the result makes thimble cooperate with needle guard again.Thereby sufficient hot water is arranged in the assurance radiator, have air to discharge at any time like this, the assurance radiator is constantly warmed oneself to user's heat supply.

The utility model compared with prior art, this device overcomes the trouble that manual air bleeding valve in the past will often open, main element is except wireway and fixed cover, mostly employing is moulded firmly and is made, and is not afraid of corrosion.Be provided with noise reduction valve, solved the noise problem that automatic exhaust steam valve produces, easy to maintenance, the blanking cover of radiator is constant, adds simple in structurely, easy to process, prevents that hot water from discharging privately, and cost is low.
