Abstract
The utility model discloses a backwater alarm device for a solar water heater, which comprises a return pipe connected with an overflow port of the solar water heater, wherein, the rear part of the return pipe is diverged into an overflow channel and an airflow channel, a normally-closed overflow valve controlled by elastic force is arranged in the overflow channel, a normally-opened airflow valve controlled by elastic force is arranged in the airflow channel, and the tail end of the airflow channel is provided with a pneumatic horn; a pressure spring is arranged between the rear part of the normally-closed overflow valve and the wall of the overflow channel, and a tension spring is arranged between the front part of the normally-opened airflow valve and the wall of the airflow channel. The device is mainly applied to the automatic alarm when an overflow pipe returns water after a water tank is full during the water supply of the solar water heater, arranges a pneumatic alarm device at a return end, utilizes the air pressure produced beforehand during the return to automatically alarm to remind a user of closing a feed cock in time and remind the user of closing a water inlet switch in time, thereby reducing the waste of water resource and possible immersion pollution.
Description
Technical field
The utility model relates to a kind of solar water heater backwater warning device.
Background technology
Present domestic domestic solar water heater popularizes amount and grows with each passing day, most of plain edition solar water heater is mainly with the natural energy source that utilizes the sun, owing to do not need other energy such as additional electrical energy, is to solve the energy-intensive best technique, and safe and reliable, very big DEVELOPMENT PROSPECT is arranged.But the overflow pipe backwater was closed untimely meeting and is caused water waste after in use water tank was filled, and also can soak sometimes to irritate in the room and cause unnecessary loss.
The utility model content
The utility model purpose is to provide a kind of more safe and reliable solar water heater backwater warning device.
To achieve these goals, the utility model adopts following technical scheme: solar water heater backwater warning device, comprise the return pipe that is connected with the overfall of solar water heater, return pipe rear portion bifurcated is overflow ducts and gas channel, be provided with the normally closed flow spill valve of elastic force control in the overflow ducts, what be provided with elastic force control in the gas channel often opens air flow valve, and the gas channel end is provided with wind-tone horn.
Be provided with compression spring between the rear portion of described normally closed flow spill valve and the overflow ducts wall, often open between draught damper front portion and the gas channel wall and be provided with tension spring.
The utility model is mainly used in when water tank is filled back overflow pipe backwater in the water process on the solar water heater and reports to the police automatically, at the backwater end a pneumatic warning device is installed, the air pressure that produces in advance when utilizing backwater is reported to the police automatically, remind the user in time to close feed cock, remind the user in time to close water inlet switch, the dirty beam of immersion that reduces water waste and may cause.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment: as shown in Figure 1, solar water heater backwater warning device, comprise the return pipe 1 that is connected with the overfall of solar water heater, return pipe 1 rear portion bifurcated is overflow ducts 4 and gas channel 6, be provided with the normally closed flow spill valve 5 of elastic force control in the overflow ducts 4, what be provided with elastic force control in the gas channel 6 often opens air flow valve 2, and gas channel 6 ends are provided with wind-tone horn 3.Be provided with compression spring between the rear portion of normally closed flow spill valve 5 and overflow ducts 4 walls, be provided with tension spring between air flow valve 2 front portions and gas channel 6 walls.
After the solar water heater main water box is filled since up and down differential pressure action at first return pipe 1 in, produce certain Pneumatic pipe cleaner and cross drainpipe and discharge, air-flow is discharged to terminal, air flow valve 2 is often opened, the warning of sounding of air-flow promotion wind-tone horn; Flow spill valve 5 is normally closed, and air-flow can only enter wind-tone horn place pipeline, extrudes when top has under the part current direction, because current pressure reduction greater than air-flow differential, can be closed air flow valve 2, opens flow spill valve 5, the part current are discharged by overfall 4, significantly reduce water waste and other loss.The backwater alarm is installed in the lower end of accompanying drawing 1 solar water heater integrated structure overfall interface tube 1.
The utility model needn't increase other energy facilities with air pressure, hydraulic pressure characteristic, saves electric energy, and the water energy has promotion prospect; It is simple and easy that device is made material, and cost is low, uses wide, safe and reliable; For saving cost, can select for use the small ball on the hand sprayer to make improvements use less as two used valves; This contrive equipment is simple in structure, makes easily, can adopt toy for children to substitute as the critical piece alarming horn, and use, installation, maintenance are conveniently.
Claims (2)
1, solar water heater backwater warning device, it is characterized in that: comprise the return pipe that is connected with the overfall of solar water heater, return pipe rear portion bifurcated is overflow ducts and gas channel, be provided with the normally closed flow spill valve of elastic force control in the overflow ducts, what be provided with elastic force control in the gas channel often opens air flow valve, and the gas channel end is provided with wind-tone horn.
