Abstract

An anti-frost valve capable of preventing a solar energy water pipe from frost crack is mounted between a solar energy water tank and a water pipe with one end connected with the solar energy water tank and the other end connected with the water pipe; an air channel is arranged on the valve body, and the air channel and a limber hole are interlocked when a sealing piece is moved; a fixed coil is arranged on the valve body, a movable coil is arranged on the sealing piece, the magnetic attractive and repulsive force are respectively generated after the fixed coil and the movable coil are energized to push the sealing piece to move. The air channel ensures air to be communicated with the inner hole of the water pipe when the limber hole is closed, therefore to drain the water in the water pipe off by utilizing the atmospheric pressure to enable the water pipe to free from freezing for waterlessness, so as to achieve the purpose of anti-freezing protection. The limber hole of the anti-frost valve is opened when the weather is not cold, at the time, the air channel is closed, and the water pipe is communicated with the solar energy water tank, therefore the anti-frost valve is ready for normal use. At the same time, the user can control the switch through wires indoors to open and close the solar energy anti-frost valve, thereby being very convenient.

Description

The antifreezing solar energy valve

Technical field

The utility model relates to a kind of anti-freeze protection device of solar water pipe, especially can be at cold weather, reach in the icing temperature environment, and protect the solar water pipe spalling that is not damaged by frost effectively.

Background technique

At present, the water tank of solar water pipe and solar energy directly links to each other and communicates, and just is full of water like this in the solar water pipe always, temperature for the environment that freezes in, the water constipation ice in the water pipe expands, the spalling water pipe causes solar energy to damage, and can't use.

Summary of the invention

In order to overcome the existing solar water pipe spalling water pipe that freezes when cold in the sky; cause the vitiable deficiency of the sun; the utility model provides a kind of frost valve; this frost valve can not only be preserved the hot water in the solar water container; water in simultaneously can also the emptying solar water pipe; make water pipe not have water freezing, reach the purpose of protection water pipe.

For achieving the above object, the utility model provides a kind of antifreezing solar energy valve, and described frost valve one end connects water pipe, and an end connects the solar energy casing, and described frost valve comprises:

The water port, it connects valve body;

Closed hole, it is arranged on a side of described water port and is communicated with the water port;

Sealing, it is arranged in the described closed hole and slides in closed hole, and has vent slot;

Air passageways, it is arranged on the both sides of described Sealing and communicates with atmosphere, and is communicated with described vent slot when Sealing sealing water port;

Moving coil, it is arranged on the top of Sealing and fixedlys connected with Sealing;

Fixed coil, itself and moving coil are oppositely arranged and are fixed on the valve body.

In preferred embodiment, be provided with groove with the closed hole relative position on the sidewall of described water port.

In preferred embodiment, the material of described Sealing can select pottery, Cuprum alloy, and stainless steel, plastics, rubber is made.

Particularly, the utility model solves the technological scheme that its technical problem adopts and is:

Between solar water container and water pipe, frost valve is installed, frost valve one end connects solar water container, and an end connects the magnetic force that electromagnetic coil produced that this frost valve utilization of water pipe is installed, and accomplishes opening and closing.When electromagnetic coil energising generation magnetic force repels each other, promote Sealing and stretch out from closed hole, close water pipe, water pipe and solar water container are disconnected, the hot water of solar water container is preserved motionless, at this moment air passageways that designs on the valve body and the vent slot on the Sealing, position are just in time consistent, communicate, form air passageways, at this moment the endoporus of water pipe is communicated with outside air by the air passageways of frost valve, and the water in the water pipe can utilize atmospheric pressure like this, is drained.

When the magnetic force that produces when electromagnetic coil energising back is inhaled mutually, the Sealing contractile motion, open and open the water port, on the valve body stagger in the position of the vent slot on air passageways and the Sealing simultaneously, closed air passageways, water pipe links to each other with solar water container and communicates, and disconnects with outside air, the hot water of solar energy casing just can flow down along water pipe like this, the normal use.So, when solar energy does not freeze at temperature,, just can normally use as long as open frost valve.Drop to when freezing at temperature, close frost valve, preserve casing hot water, water in the emptying water pipe makes water pipe not have water freezing, reaches antifreezing effect.

The beneficial effects of the utility model are, at cold weather, in the time of water freezing, can preserve solar water, and the water in the emptying water pipe easily makes water pipe not have water freezing simultaneously, has avoided because of icing by the result of spalling.Time spent, the water port is just normal uses as long as open, with after close again, just the emptying water pipe can.When weather is not cold, allow water pipe be in open mode, the normal use always.

Description of drawings

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

Fig. 1 is the sectional drawing of frost valve of the present utility model under the water pipe open mode.

Fig. 2 is the sectional drawing of frost valve of the present utility model under the water pipe closed condition.

Fig. 3 is a frost valve valve body sectional view of the present utility model.

Fig. 4 is the connection diagram of frost valve Sealing of the present utility model and vent slot.

Among the figure: 1. water port, 2. closed hole, 3. air passageways, 4. air passageways, 5. vent slot, 6. Sealing, 7. fixed coil, 8. sealed screw, 9. movable coil.A end: connect solar water pipe, B termination solar water container.

Embodiment

Among Fig. 1, Sealing 6 is gone up, and water port 1 is in opening state, and current can pass through.4 sealed 6 of air passageways 3 and air passagewayss disconnect, and are in closed condition, and air can not pass through.

Among Fig. 2,1 sealed 6 shutoff in water port, water can not pass through.Air enters vent slot 5 by air passageways 3, enters air passageways 4, enters water port 1 again, enters in the water pipe.For the water port, Sealing is the water port endoporus to the A end; Sealing is hole outside the water port to the B end.

Among Fig. 4, with the column part of electronic coil corresponding end be hermetic unit.The water port is closed in hermetic unit position in the water port, closes air passageways in the air passageways position.

In the embodiment shown in fig. 1, movable coil 9 and fixed coil 7 move to together when magnetic force is inhaled mutually, and Sealing 6 is opened water port 1 from closed hole 2 withdrawals like this, and the air passageways 3 and 4 on vent slot 5 and the valve body staggers on the Sealing 6 simultaneously, and air is disconnected.Solar energy casing and water pipe communicate like this, and air passageways is closed on the valve body, and the hot water of solar energy normally uses.

In embodiment illustrated in fig. 2, movable coil 9 and fixed coil 7, when the magnetic force of coil repelled each other, Sealing 6 stretched out from closed hole 2, disconnected and had closed water port 1, and the hot water of preserving the solar energy casing is motionless.Simultaneously air passageways 3 and air passageways 4, just in time with vent slot 5 position consistency of Sealing, air communicates, like this, the air of outside just communicates with the endoporus of water pipe, can utilize atmospheric pressure, water in the emptying water pipe prevents that water freezing from producing the spalling destruction easily.
