Abstract
A kind of automatic exhauster for air heater, be made up of main valve body, spool, valve gap, plug screw, back-up ring and pad, main valve body exports with radiator and is threaded, and is provided with inlet channel, valve core chamber, exhaust passage and water storage passage in main valve body; Spool comprises stepped solid of rotation main valve plug and Returnning spring, is positioned at the valve core chamber of main valve body, the back-up ring of restricted spool travel in valve core chamber; Be lined with gasket seal between valve gap with main valve body and be connected with bolt, in valve gap, being provided with accessory channel.The convenient processing of the utility model, cost is low, and practicability is good, has stronger generalization; Utilize buoyancy of water and pressure realize the automatic-discharging of gas in radiator and spilling of water in radiator can be prevented, the needs of real life can be met.
Description
Technical field
The utility model relates to a kind of automatic exhauster for air heater, particularly household central heating automatic exhaust device.
Background technique
The northern area of China winter severe cold, for ensureing that people have warm, a comfortable life, study and work environment in the winter of cold, in residential building building, school and other indoor public places be all generally provided with heating equipment.Now widely used heating equipment mainly water heating type radiator, is transported in interior conduit by after water heating to make room temperature raise.At In The Initial Period Of Heating, can there is a certain amount of air in radiator inner chamber, formed " gas blocks up ", causes hot water circuit not smooth, affect heating effect.Therefore outlet valve is all installed on the appropriate location of radiator to discharge the additional air in radiator pipeline.Heating air vent valve common is at present threaded to be arranged on the artificial outlet valve of heating equipment end eminence, needs manually to turn on bonnet and discharged by the exhaust port on valve body by the air in radiator.The use of this outlet valve manually also exists much inconvenience: 1, owing to often contacting water and air, the easy corrosion of bonnet, bonnet place can be accumulated in containing much impurity in the water of heating water, the volume of bonnet own again very little, stress surface is narrow, require great effort all very much when therefore turning on bonnet at every turn, directly not easily turn on hand; 2, after turning on bonnet, first discharging air in exhaust port, is then gas-liquid mixture, is finally water, at this moment closes bonnet, and visible operation is very inconvenient, and during exhaust, easy water column splashes; 3, Long-Time Service can cause bonnet screw thread place serious wear, screw sternly, causes leaking.
Model utility content
The utility model is in order to overcome above-mentioned prior art defect, a kind of automatic exhauster for air heater is provided, realize automatically air unnecessary in radiator being discharged, and effectively prevent the spilling of hot water in radiator, improve the Security of the heating effect of heating equipment and use, convenience.
To achieve these goals, the utility model adopts following technological scheme.
A kind of automatic exhauster for air heater, comprise main valve body, spool, valve gap, plug screw, it is characterized in that: described main valve body exports with radiator and is threaded, inlet channel, valve core chamber, exhaust passage and water storage passage is provided with in described main valve body, described spool comprises stepped solid of rotation main valve plug and Returnning spring, described spool is positioned at the valve core chamber of described main valve body, the back-up ring of restriction spool travel is provided with in described valve core chamber, be lined with gasket seal between described valve gap with described main valve body and be connected with bolt, in described valve gap, being provided with accessory channel.
The cross-section area of the piston portion of described main valve plug is greater than the cross-section area of described exhaust passage.
The beneficial effects of the utility model are: automatically discharged by air unnecessary in radiator, and effectively prevent the spilling of hot water in radiator, improve the Security of the heating effect of heating equipment and use, convenience.
Accompanying drawing explanation
Fig. 1 is general structure schematic diagram of the present utility model.
Fig. 2 is valve core structure schematic diagram of the present utility model.
Fig. 3 is main valve body structural representation of the present utility model.
Fig. 4 is valve cover structure schematic diagram of the present utility model.
Embodiment
As shown in figures 1-4, a kind of automatic exhauster for air heater, by main valve body 1, spool 2, back-up ring 3, large plug screw 4, little plug screw 5, valve gap 6, pad 7 forms.
The threaded coupling 15 of main valve body 1 is connected with the upper end outlet of radiator, and the air in radiator and water enter venting gas appliance thus.Because air density is much smaller than the density of water, air can rise, and discharges from water storage passage 14 via exhaust passage 13; Under gravity, first water will flow into inlet channel 11.When the water yield starts to increase, water will be had to enter valve core chamber 12 and water storage passage 14, the water level now in valve core chamber 12 and water storage passage 14 is contour.Continuing to increase with rate of water added, spool 2 in valve core chamber 12 raises gradually under the effect of buoyancy of water, water level simultaneously in valve core chamber 12 is by lower than the water level in water storage passage 14, due to the effect of accessory channel 61 in valve gap 6, guarantee that spool 2 is before blocking exhaust passage 13, the water in water storage passage 14 can not enter exhaust passage.In the effect lower valve core room 12 of water-head, the pressure of water will increase, and piston portion 21 cross-section area of spool 2 is comparatively large, and therefore spool 2 is subject to the effect of larger upward pressure.Under the double action of buoyancy of water and pressure, spool 2 blocks exhaust passage 13 gradually, stops the water in water storage passage 14 to overflow.Back-up ring 3 is spacing for spool 2, the spilling preventing from spool 2 from opening exhaust passage 13 from lower end because position is too high causing water.When heating installation is stopped using, water will from valve core chamber 12, and water storage passage 14 and inlet channel 11 are back in radiator, and spool 2 returns valve core chamber 12 under the effect of Returnning spring 23 and own wt.
Below by reference to the accompanying drawings a kind of automatic exhauster for air heater of the present utility model is explained, but protection domain of the present utility model is not limited to this, allly all belongs to based on the change done by above embodiment or distortion the protection domain that the utility model requires.
