Description
Technical field
The utility model relates to a kind of automatic exhaust device of heating system, belongs to heating heating technology field.
Background technique
At present, the valve air relief that heating system is used, in use for some time, and because of malfunctioning after impurity obstruction exhaust port in pipeline, can not automatic vent.The maintenance man can only insert exhaust port exhaust by force with thin wire, and this method is leaked the exhaust port bad seals sometimes, and also row holds one's breath sometimes, and the maintenance man can only pull down automatic vent, connect the exhaust of hose hand-actuated, can lose large water gaging.After draining gas, then automatic air discharging is arranged on to original position is used as plug and uses, valve air relief performs practically no function.The malfunctioning main cause of automatic air discharging is the obstructions such as foreign material that heating system pipeline iron rust and replacing pipeline are brought into, and causing can not automatic vent.Because the automatic deflation valve outlet hole is very little, be very easy to stop up.The spring laid-up of valve air relief internal control exhaust port exhaust is easy to distortion, if camber of spring, valve air relief drains gas the final vacuum hole and leaks, and the maintenance man is difficult to repair.In the interior water of preliminary heating period heating system, impurity is the main cause that causes automatic bleed valve malfunctioning.The various maintenance tasks of preliminary heating period are very large, and the maintenance man does not have energy and time detachable maintaining automatic bleed valve.Increase maintenance difficulty, increased amount of maintenance.
The model utility content
The utility model purpose is to provide a kind of automatic exhaust device of heating system, garbage barrier net is set below automatic control pressure vent, prevent that exhaust port from stopping up, reduce heating system because of manual exhaust, the discharge water water that causes and the waste of heat, solve the problem existed in background technique.
The technical solution of the utility model is: a kind of automatic exhaust device of heating system, comprise that exhaust port, automatic control pressure vent, cursory, garbage barrier net, exhaust spring, exhaust port leakproof are emitted, the blowdown valve leakproof is emitted and blowdown valve, the automatic control pressure vent top is provided with exhaust port, exhaust port inside is provided with exhaust spring, outer end is provided with the exhaust port leakproof and emits, it is cursory that automatic control pressure vent inside is provided with, below is provided with garbage barrier net, the garbage barrier net below is communicated with blowdown valve, the blowdown valve outer end is provided with the blowdown valve leakproof and emits, and the automatic control pressure vent bottom is communicated with heating system.
Described garbage barrier net is fixed on the below of automatic control pressure vent by screw thread, and is positioned at the blowdown valve top, and the automatic control pressure vent bottom is communicated with heating system by outer screw thread.
Described blowdown valve is provided with the blowdown valve switch.
Described garbage barrier net mesh is less than exhaust port.
The beneficial effects of the utility model are: stop because impurity in water in heating system causes automatic vent malfunctioning, reduce heating system because of manual exhaust, the discharge water water that causes and the waste of heat, reduce maintenance cost.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model skirt elbow structure schematic diagram;
In figure: exhaust port 1, automatic control pressure vent 2, cursory 3, garbage barrier net 4, screw thread 5, outer screw thread 6, exhaust spring 7, exhaust port leakproof emit 8, blowdown valve switch 9, blowdown valve leakproof emit 10, blowdown valve 11, interior screw thread 12, elbow 13, soft screw thread 14.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, a kind of automatic exhaust device of heating system, comprise exhaust port 1, automatic control pressure vent 2, cursory 3, garbage barrier net 4, screw thread 5, outer screw thread 6, exhaust spring 7, the exhaust port leakproof emits 8, blowdown valve switch 9, the blowdown valve leakproof emits 10 and blowdown valve 11, automatic control pressure vent 2 tops are provided with exhaust port 1, exhaust port 1 inside is provided with exhaust spring 7, outer end is provided with the exhaust port leakproof and emits 8, automatic control pressure vent 2 inside are provided with cursory 3, garbage barrier net 4 is fixed on the below of automatic control pressure vent 2 by screw thread 5, and be positioned at blowdown valve 11 tops, garbage barrier net 4 belows are communicated with blowdown valve 11, garbage barrier net 4 mesh are less than exhaust port 1, blowdown valve 11 outer ends are provided with the blowdown valve leakproof and emit 10, blowdown valve 11 is provided with blowdown valve switch 9, blowdown valve switch 9 adopts the safety water design, automatic control pressure vent 2 bottoms are communicated with heating system by outer screw thread 6.
With reference to accompanying drawing 2, the skirt elbow comprises interior screw thread 12, elbow 13, soft screw thread 14, and elbow 13 1 ends are provided with interior screw thread 12, and interior screw thread 12 is complementary with blowdown valve 11 ends, and Ying Yiduan is provided with soft screw thread 14.
Working procedure: when heating system operation automatic bleed valve can not automatic vent, at first back out the blowdown valve leakproof and emit 10, will band in the skirt elbow of screw thread one end be arranged on blowdown valve 11 outer ends, the other end connects flexible pipe.Open blowdown valve switch 9, the blowdown exhaust discharges water.After completing, pull down the skirt elbow, the blowdown valve leakproof of screwing on emits 10.If dirt stops up blowdown valve, the blowdown exhaust that can not discharge water, clean garbage barrier net 4 or draping.While this situation occurring, first close automatic control pressure vent, the valve of pipe control.Open blowdown valve switch 9, after the automatic control pressure vent pressure release, pull down automatic control pressure vent.Back out screw thread 5, garbage barrier net 4 is pulled down, clean garbage barrier net 4 or change rear the recovery.
