Abstract
The utility model discloses an antifreezing valve for a solar water heater. The antifreezing valve for a solar water heater is provided with a spherical shell body above which an air inlet is arranged. A spherical air chamber is arranged below the spherical shell body. A water inlet taper pipe is opposite to a small opening of a water outlet taper pipe in the spherical shell body. A gap is formed between the water inlet taper pipe and the small opening of a water outlet taper pipe. A cylindrical metal jacket is sheathed outside the two opposite taper pipes. The antifreezing valve for a solar water heater has the advantages of high sensitivity, safe emptying and freezing prevention, simple structure, and convenient operation.
Description
The utility model relates to a kind of frost valve of solar water heater.
Frost valve two conical pipes of solar water heater are relative now, gapped between the relative tapered pipe, when solar water heater and indoor height difference during greater than 12 meters, the flow velocity of water intaking strengthens, unexpected throttle down in the water intaking process, then water is scurried water suddenly from the gap of two tapering pipes, enters tracheae, tracheae is freezed to death, can not air inlet.
The utility model provides a kind of solar water heater frost valve, and it is highly sensitive, and is antifreeze reliable, simple in structure.
The technical solution of the utility model is as follows:
This valve has a spherical shell, is suction port on it, and it is down spherical air chamber, and water inlet tapering pipe is relative with the osculum of water outlet tapering pipe in spherical shell, and the centre is gapped, two relative tapering pipe overcoat one cylindrical metal sleeves.
The gap of two above-mentioned tapering pipes, its preferred version are 0.5-1mm.
Advantage of the present utility model is: 1, highly sensitive, and rush to gas with air valve and enter the gap, just can destroy siphon and make between the two tapering pipes and stop, make pipeline emptying.2, have metallic sheath to avoid the tracheae water inlet, antifreezing effect is safe and reliable.2, easy and simple to handle being easy to accepted by the user.
Fig. 1 is the utility model cross-sectional view;
Fig. 2 is the work schematic representation that the utility model inserts solar water heater.
The utility model is described in further detail below in conjunction with accompanying drawing.
By figure, Fig. 2 can see that this valve has a spherical shell (7), is suction port (3) on it, it connects tracheae (10); It is down spherical air chamber (6), and water inlet tapering pipe (1) is relative with the osculum of water outlet tapering pipe (4) in spherical shell, centre gapped (5), and its gap is 0.5-1mm, two relative tapering pipe overcoat one cylindrical copper sheathings (2).Water inlet tapering pipe connects outdoor upper and lower water pipe (11), and water outlet tapering pipe connects water tank (8) by the road.
When opening water supply valve door (13) on the need during water, water is flowing into water tank (8) in the direction of arrows in frost valve (9) under the effect of pressure, after water tank water is full, and throttle down (13); Winter, the outer tube Louis was frozen, close water supply valve after, open outlet valve (12), open air valve (15) again, gas enters gap (5) through tracheae (10) siphonage is cut off, and makes the current in the outer pipeline (11) clean, the realization emptying.
When taking hot water, open water supply valve (13) earlier, push up one cold water, make pipeline be full of water, open flowing water Valve (12) again, can start siphonage, hot water is drawn to get off use, (16) are shower nozzle, and (14) are modulating valve.When the drop of solar water heater during greater than 12 meters because of copper sheathing is arranged, can vertically not scurry water, to guarantee the unblocked of tracheae from the gap yet.
Claims (2)
1, a kind of solar water heater frost valve, it has a spherical shell (7), it on it suction port (3), it is spherical air chamber (6) down, water inlet tapering pipe (1) is relative with the osculum of water outlet tapering pipe (4) in spherical shell, middle gapped (5) is characterized in that: two relative tapering pipe overcoat one cylindrical metal sleeves (2).
2, solar water heater frost valve according to claim 1 is characterized in that: the preferred version in the gap of its two tapering pipes is 0.5-1mm.
