Abstract

The utility model discloses an automatic exhaust siphon type antifreezing solar water heater, which effectively solves the problems of drainage and antifreezing for a siphon. An exhaust port is opened on a connection part between the siphon and a water outlet pipe. An electric control air outlet valve is connected to the exhaust port. A switch, a power supply, the electric control air outlet valve are connected together through wires. If only the switch is pressed, a pipeline can be drained. The utility model has the advantages of thorough drainage, high speed, stable and reliable performance of a whole device and low cost.

Description

Automatic vent hydrocone type anti-freezing solar water heater

The utility model relates to solar water heater, especially automatic vent hydrocone type anti-freezing solar water heater.

The hydrocone type solar water heater, use very general, but because storage tank is positioned at outdoorly, and upper and lower conduit must have one section outdoor, to winter, if not emptying upper and lower conduit certainly will cause freezing accident.In order to make the upper and lower conduit emptying, need make the siphon pipe upper end open, air is entered, have in the prior art and adopt ball valve to control the pass of above-mentioned opening and close, it install complexity, debugging requires high, the outdoor work difficulty, and service life is short, after a period of time, often produce gas leak phenomenon, normally siphon.

The purpose of this utility model is the shortcoming that overcomes prior art, provides a kind of upper and lower conduit emptying only to need Push switch, fast, safety, convenience, can not produce the automatic vent hydrocone type anti-freezing solar water heater of gas leakage accident.

For achieving the above object, the utility model is by the following technical solutions:

A kind of automatic vent hydrocone type anti-freezing solar water heater, comprise water tank, siphon pipe, outlet pipe and overflow pipe, it is characterized in that described siphon pipe and outlet pipe junction surface have an exhaust outlet, be connected to an automatically controlled air bleeding valve on the exhaust outlet, lead is connected on automatically controlled air bleeding valve and the power supply by switch.

Described automatically controlled air bleeding valve is a magnetic valve, its bottom one side is provided with an interface and is connected with described exhaust outlet, interface and shell connecting portion have a hole, the lateral wall in hole is provided with a circle sealing gasket, piston base is close on the sealing gasket just, the downside of piston base has a spring, and has a spring bottom plate to be positioned at the opening part of interface; The piston base central part stretches into a piston push rod in the magnetic valve housing, the bottom is fixed on the piston base; Be fixed with an electromagnet at the solenoid valve base opposite side, the outside near electromagnet, be provided with one with its energising after the identical magnetic patch of polarity, magnetic patch is located at the arm bar lower end of a leverage, there is a moving fulcrum at the arm bar middle part, flexibly connects with pole one end, and the other end of pole is fixed on the outer casing inner wall, the upper end of arm bar reaches piston push rod top just, and the contact position is provided with moving fulcrum.

The utlity model has following effect:

1. thoroughly finish preventing freeze in winter, intestine evacuation velocity is very fast, can not produce the pipeline freezing accident, and is safe and reliable.

2. simple to operate: as only to need Push switch, just can under solenoid control, realize emptying.

3. stable performance, low cost of manufacture.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the utility model overall structure generalized section.

Structural profile schematic diagram when Fig. 3 opens for the utility model magnetic valve.

Fig. 4 is the utility model electrical schematic diagram.

As shown in Figure 1, this automatic vent hydrocone type anti-freezing solar water heater is made of water tank 1, siphon pipe 2, outlet pipe 3 and overflow pipe 4, also has corresponding solar energy heating equipment.Water tank 1 general frame is in outdoor, siphon pipe 2, one section of outlet pipe 3 also is exposed to outdoor, junction surface at siphon pipe 2 and outlet pipe 3 has an exhaust outlet, be connected to an automatically controlled air bleeding valve 5 on the exhaust outlet, this automatically controlled air bleeding valve 5 is a magnetic valve, as shown in Figure 2, its bottom one side is provided with an interface 13 and is connected with described exhaust outlet, and interface 13 outer walls have the screw thread screw thread, directly screw on exhaust outlet, interface 13 has a hole with shell 7 connecting portions, this hole is positioned at solenoid valve base, is in the interface 13, and the lateral wall in hole is provided with a sealing gasket 9, there is the upper surface of a piston base 10 to be close to just on the sealing gasket 9, with interface 13 inside and outside seal isolation.The downside of piston base 10 is provided with a spring 11, and it has a spring bottom plate 12 to be positioned at the opening part of interface 13 down, is supporting spring 11, and the elastic force effect makes piston base 10 upwards closely be contacted with on the sealing gasket 9 again.Piston base 10 middle parts are stretched into a piston push rod 8 in the magnetic valve housing, its bottom is fixed on the piston base 10, piston of falling the T-shape of piston push rod 8 and piston base 10 common formations.In solenoid valve base opposite side internal fixation one electromagnet 17 is arranged, the outside near electromagnet 17, be provided with one with the identical magnetic patch 18 of polarity after its energising, magnetic patch 18 is located at arm bar 16 lower ends of a leverage, there is a moving fulcrum 15 at arm bar 16 middle parts, flexibly connect with pole 14 1 ends, the other end of pole 14 is fixed on shell 7 inwalls, forms lever dolly.The upper end of arm bar 16 reaches the top of piston push rod 8 just, and both contact positions are provided with moving fulcrum 20, one section leads 6 and are connected on automatically controlled air bleeding valve 5 and the power supply V by K switch, and the power connection 19 of electromagnet 17 is connected to lead 6 one ends.

The course of work is as follows:

During normal bathing, K switch is closed, the magnetic valve outage, state as shown in Figure 2, magnetic patch 18 is in original position, exhaust close, normally siphon of siphon pipe 2.

Bathing finishes, and during emptying, opens K switch, electromagnet 17 is subjected to electricity in the magnetic valve, produces magnetic, because electromagnet 17 is identical with magnetic patch 18 relative side poles, repel mutually, magnetic patch 18 is outwards moved, utilize lever principle, arm bar 16 promotes piston push rod 8 and tilts, piston base 10 1 sides are separated with sealing gasket 9, and Exhaust Open, air enter siphon pipe 2, siphonage lost efficacy, the water emptying immediately in the pipeline.Close K switch after the emptying again, deenergization V.State as shown in Figure 3.

K switch is loaded on indoor, controls very convenient.
