Abstract
The utility model relates to an automatic drain valve which is applied to the field of the freezing prevention of the water pipes of outdoor water heaters, such as solar water heaters and the like, and comprises an electromagnetic valve, a three-way valve, a threaded cover with holes and a rubber pad, wherein an upper section of the three-way valve is connected with the electromagnetic valve, a lower section of the three-way valve is connected with a sewage pipeline, a middle branch section of the three-way valve is connected with the threaded cover with the holes, the rubber pad is clamped in the threaded cover with the holes, the structure of the rubber pad is in a wheel type, an inner core is solid, the middle is hollow, and the diameter of the inner core of the rubber pad is slightly greater than the diameter of the center small holes of the threaded cover. The automatic drain valve has simple structure and convenient control, is used on the outdoor water heaters, such as the solar water heaters and the like, and can drain water stored in the independent water pipes completely, the water is not stored in the water pipes, the water pipes are not frozen in winter, and the water heaters can also be used normally at weather below the freezing point.
Description
Technical field
The utility model relates to a kind of automatic exhaust-valve, is specifically related to a kind of water pipe anti-freezing field that is applied to outdoor water heaters such as solar water heater, can be with the valve of the automatic emptying of water in the pipeline.
Background technique
At present, the outdoor water heaters such as solar water heater that the most of family in the north installs, because yard piping freezed and can't normally use winter, the service time and the scope of this class water heater have been limited greatly, and the yard piping of fraction water heater adopts electric heating wire to wrap up to be incubated, and the major defect of its existence is the waste electric energy.For the outdoor water heater of this class of solar water heater is normally used winter, be badly in need of a kind of automatic exhaust-valve that can on yard piping, install, with the automatic emptying of water in the pipeline, not only winter, pipeline did not freeze, and not loss electric energy.
The model utility content
The purpose of this utility model is, a kind of automatic exhaust-valve is provided, can be with the automatic emptying of water in the pipeline, and make outdoor water heater yard piping such as solar water heater not freeze normal the use winter.
The utility model adopts following technological scheme:
A kind of automatic exhaust-valve, connected element are three-way valve, and joint links to each other with solenoid valve on the described three-way valve, and following joint links to each other with drainage pipeline, and the intermediate section detail links to each other with threaded cap with holes; Card has rubber seal in the described threaded cap, and the threaded cap center is provided with aperture; Described rubber seal is the wheel shape, be opening shape around the rubber seal inner core, and the inner core position is relative with threaded cap central small hole position.
Further, described rubber seal inner core diameter is slightly larger than threaded cap central small hole diameter.
Its working principle is: open solenoid valve during water, hot water is flowed out by natural pressure from water heater, and rubber seal is under hydraulic action, and the rubber seal inner core is blocked the threaded cap central small hole, and hot water goes out to enter pipeline by throttling under the three-way valve; Close solenoid valve after water finishes, rubber seal inner core one side hydraulic pressure disappears, and rubber seal inner core opposite side moves under the barometric pressure effect, makes outside air enter pipeline through vacancy in the middle of the rubber seal, makes the automatic emptying of water in the pipeline.
Preferably, described automatic exhaust-valve is vertically installed on pipeline.
Advantage of the present utility model with good effect is: adopt three-way valve to be connected, and simple in structure; The electromagnetic valve switch is adopted on top, and is easy to use; Cooperate electromagnetic valve switch, the rubber seal inner core is controlled automatically by inside and outside physics differential pressure action, makes water emptying in the pipeline, and winter, pipeline did not freeze, and outdoor water heater such as solar water heater normally uses winter.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings
Fig. 1 is the automatic exhaust-valve example structure of a utility model schematic representation;
Fig. 2 is the automatic exhaust-valve rubber seal of the utility model embodiment's a structural representation.
Label declaration:
1. solenoid valve, 2. three-way valve 3. saves on the three-way valve, 4. three-way valve joint down, 5. three-way valve intermediate section detail,
6. threaded cap with holes, 7. threaded cap central small hole, 8. rubber seal, 9. rubber seal inner core, 10. rubber seal intermediate portion.
Embodiment
A kind of automatic exhaust-valve, as shown in Figure 1, connected element is a three-way valve 2, three-way valve 2 comprise save 3 on the three-way valve, three-way valve joint 4 and three-way valve intermediate section detail 5 down.Joint 3 links to each other with solenoid valve 1 on the three-way valve, and three-way valve saves 4 down and links to each other with the drainage pipeline (not shown), and three-way valve intermediate section detail 5 links to each other with threaded cap 6 with holes; Card has rubber seal 8 in the threaded cap 6 simultaneously with holes, rubber seal 8 structures as shown in Figure 2, be the wheel shape, rubber seal inner core 9 is real, rubber seal intermediate portion 10 is a vacancy, the position of rubber seal inner core 9 is relative with threaded cap central small hole 7 positions, and rubber seal inner core 9 can be blocked threaded cap central small hole 7 under pressure.
The utility model working procedure is as follows:
When water, open solenoid valve 1, hot water saves 3 on water heater flows out through solenoid valve 1 and three-way valve by natural pressure, at three-way valve intermediate section detail 5 places, be stuck in rubber seal 8 in the threaded cap with holes 6 under hydraulic action, rubber seal inner core 9 is blocked threaded cap central small hole 7, and hot water saves 4 outflows down by three-way valve and enters pipeline.
After finishing, water closes solenoid valve 1, the hydraulic pressure of three-way valve intermediate section detail 5 place's sides is close to suddenly and disappears, be that rubber seal inner core 9 one side hydraulic pressures disappear, rubber seal inner core 9 opposite sides move under the barometric pressure effect, make outside air enter pipeline, make the automatic emptying of water in the pipeline through 10 vacancies, rubber seal intermediate portion.
