Abstract

The utility model discloses an emptying device of a solar water heater, which comprises a buffer room. An air inlet pipe is arranged on the buffer room, and the water outlet of the buffer room is provided with a sealing plug. The sealing plug comprises a plug body and a telescopic bag body, the plug body is arranged at the outer side of the buffer room, and the telescopic bag body is arranged in the buffer room and is communicated with the air inlet pipe. The plug body and the telescopic bag body are connected through a guide rod, and the guide rod penetrates through the telescopic bag body and extends into the air inlet pipe. A spring is arranged between the inner wall of the air inlet pipe and the guide rod, and the spring is sheathed on the guide rod. The spring is arranged in the air inlet pipe, so blocking is reduced at the water outlet, the water outlet is not easy to scale, and the water flow is smoother. The spring is completely isolated with water and is not corroded by water, the service life of the spring is ensured, and the spring is conveniently installed and disassembled. The guide rod penetrates through the telescopic bag body through the water outlet and extends into the air inlet pipe, so the plug body is ensured not to deviate the water outlet. A vent groove is arranged on the guide rod, which is beneficial to an inflation valve to inflate the telescopic air bag. Thus, the air path is not blocked.

Description

The solar water heater emptier

Technical field

The utility model relates to solar water heater, relates in particular to a kind of exhaust-valve of solar water heater.

Background technology

Though can effectively the water in the solar water pipe be drained, still there are some problems in the solar energy exhaust-valve that uses at present; Can not satisfy needs of people, existing a kind of emptier is applied to the emptying that surge chamber is used for solar water heater in this emptier; Be provided with the mouth of a river down at the top of surge chamber, place, the following mouth of a river has adopted the pneumatic valve that seals to come the mouth of a river under the shutoff, and this seals between cock body and the flexible utricule of valve and is provided with back-moving spring; This problem of sealing the valve existence is that back-moving spring often ducks in drink, and is prone to by aqueous corrosion; Influence the service life of spring and the normal use of solar energy, and spring is positioned at down place, the mouth of a river, is positioned on the passage of current; Influence the unobstructed of current easily and flow, and long-term the use, articulate incrustation scale on the spring easily; Build-up of limescale influences the water outlet of water tank easily, and therefore the exhaust-valve of this solar water heater also need improve.

Summary of the invention

The utility model technical problem to be solved is: the emptier that a kind of solar water heater is provided.

For solving the problems of the technologies described above, the technical scheme of the utility model is: the solar water heater emptier comprises a surge chamber that is provided with upper and lower conduit; Said surge chamber is provided with air inlet pipe; The top of said surge chamber is provided with down the mouth of a river, and place, the said mouth of a river down is provided with sealing plug, and said sealing plug comprises cock body and flexible utricule; Said cock body is arranged at the outside of said surge chamber; Said flexible utricule is arranged at said surge chamber inside and is communicated with said air inlet pipe, and said cock body is connected through a guide post with said flexible utricule, and said guide post runs through said flexible utricule and stretches in the said air inlet pipe; Be provided with spring between said air inlet pipe inwall and the said guide post, said spring housing is located on the said guide post.

As a kind of improvement, said guide post surface is provided with air channel.

As a kind of improvement, said flexible utricule is fixed on the said surge chamber bottom interior wall.

Owing to adopted technique scheme, the utility model is arranged on spring in the air inlet pipe, the obstruction that place, the mouth of a river is reduced; And the following mouth of a river is difficult for articulating incrustation scale; Make current more unobstructed, and spring is complete and water is isolated, and avoids by aqueous corrosion; Prolong the service life of spring, made things convenient for installing/dismounting; Guide post runs through flexible utricule by the following mouth of a river and stretches in the air inlet pipe, has guaranteed that cock body does not depart from the mouth of a river down, and guide post is provided with air channel, helps charge valve extension airbag is inflated, and does not stop up gas circuit.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the structural representation of the utility model embodiment;

Among the figure: the 10-solar water heater water tank; The 20-surge chamber; The 21-extension; The 22-upper and lower conduit; The 23-air inlet pipe; The mouth of a river under the 24-; The 31-cock body; The 32-utricule that stretches; The 33-guide post; The 331-air channel; The 34-spring; The 40-charge valve; 50-uses penstock.

The specific embodiment

As shown in Figure 1; The solar energy emptier comprises a surge chamber 20 that is provided with upper and lower conduit 22, and the top of surge chamber 20 is installed in the outlet pass place of solar water heater water tank 10, and surge chamber 20 is provided with air inlet pipe 23; The top of surge chamber 20 is provided with the extension 21 and the following mouth of a river 24; 24 places, the following mouth of a river are provided with sealing plug, and sealing plug comprises cock body 31 and flexible utricule 32, and cock body 31 is arranged at the outside of surge chamber 20 and is positioned at the water tank 10 of solar water heater.Flexible utricule is arranged on surge chamber 20 bottom interior wall and with air inlet pipe 23 and is communicated with; Cock body 31 is connected through a guide post 33 with flexible utricule 32; Guide post 33 runs through flexible utricule 32 and stretches in the air inlet pipe 23, and guide post 33 is provided with air channel 331, prevents that guide post 33 from stopping up air inlet pipe 23 and influencing charge valve 40 inflations; Be provided with spring 34 between air inlet pipe 23 inwalls and the guide post 33, spring 34 is set on the guide post 33.

When charge valve 40 unaerateds, cock body 31 is close to the end face of surge chamber 20 under the active force of spring 34, will descend the mouth of a river 24 sealings; When charge valve 40 inflations, flexible utricule 32 is heaved, and upwards promotes cock body 31, and cock body 31 and surge chamber 20 are broken away from, and the following mouth of a river 24 leads to.

The operation principle of present embodiment is: on the solar water heater during water; Current flow into surge chamber 20 through upper and lower conduit 22; This at present the switch at the mouth of a river 24 do not influence water on the solar energy, if down open at the mouth of a river 24, current are by in the following mouth of a river on the surge chamber 20 and the extension 21 inflow water tanks 10; If the mouth of a river is closed down, current are flowed in the water tank 10 by the extension on the surge chamber 20 21; During emptying; Bleed off the gas in the flexible utricule 32; Make cock body 31 under the active force of spring 34, be close to the end face of surge chamber 20, block down the mouth of a river 24, under atmospheric effect; Extension 21 will be outside upper and lower conduit 22 effusers with the water in the surge chamber 20, and the direction of current is shown in arrow among Fig. 1; When using solar water heater, charge valve 40 inflations, flexible utricule 32 is heaved; Promote cock body 31 and break away from surge chamber, the following mouth of a river 24 leads to, and the hot water in the water tank 10 gets into surge chambers 20 by the following mouth of a river 24; Flow out along upper and lower conduit 22, open during use with penstock 50, hot water flows out.

For strengthening the practicality of the utility model; The utility model can also be employed in increases a magnetic valve on the loading line; Water meter or flowmeter are installed on upper and lower conduit, and a controller are installed are controlled magnetic valve and flowmeter, realize filling up the automatic charging-discharging function of pipeline; And control water filling and discharge time, control water injection rate and waterdrainage amount.
