Abstract
The utility model discloses a solar water heater with a pipeline emptying device, which is provided with a heat collection device and a water tank of which the lower part is connected with an emptying device; the emptying device is provided with a valve body which is provided with a water inlet communicated with the water tank and a water outlet of water supply and water drainage; an air inlet is arranged at the upper surface; a valve rod is arranged in the valve body; a spring is sheathed on the rob; one end of the valve rod is led in the water inlet of the water tank; the valve rod at the position of the water inlet is sheathed with a valve sheet; the other end of the valve rod is connected with a stress plate, and a rubber bowl is arranged out of the plate; an air inlet is arranged at the outer side of the rubber bowl; the air inlet is communicated with an air guide tube and an air bag. The pipeline emptying device can prevent the pipeline from being frozen in winter and can improve utilization rate and diffusion rates of the solar water heater.
Description
The utility model relates to a kind of solar water heater, is a kind of solar water heater with pipeline emptying device specifically.
Present solar water heater does not have pipeline emptying device, and in northerly winter, towards the water pipe easy freezing of roof, influence is normally used, and then influences popularizing of solar water heater.
The purpose of this utility model is to provide a kind of solar water heater with pipeline emptying device, avoids freezing of pipeline in winter, improves the utilization rate of solar water heater.
The technical solution of the utility model is as follows:
This water heater has heat collector, water tank, and the bottom of water tank connects an emptying device, and it has a valve body, and valve body has the water inlet of water flowing case, and the delivery port of logical upper and lower water drives gas port above into; One valve rod is arranged in the valve body, be with spring on this bar, an end of valve rod feeds the water inlet of water tank, and cover one cuts down sheet on the valve rod of water inlet; The other end of valve rod connects stressed plate, and this plate is outward a leather cup, and the inlet plenum of sealing is arranged in the outside of leather cup, and there are self-locking device and air inlet in this chamber, and air inlet connects wireway and air bag.
This solar water heater is equipped with automatic water-supply apparatus, this device has a secondary water tank, its position is higher than water tank, secondary water tank connects an automatic loading water pipe, this pipe is communicated with running water pipe, and the automatic loading water pipe connects a ball-cock assembly in secondary water tank, has pipe to be communicated with water tank in the secondary water tank, upper vent at emptying device connects a water pipe, feeds the top of water tank.
Advantage of the present utility model is: 1, pipeline emptying device can prevent from winter to freeze, and improves the utilization rate and the popularity rate of solar water heater.2, automatic loading water can make things convenient for spring, summer in autumn to use, need not control and add water, cold water directly injects the bottom of water tank, can be with the hot water emersion in the vacuum tube, secondary water tank is placed roof itself also the certain energy income, has increased the use amount of hot water, can be from the water intaking suitable for reading of water tank, use hot water always, also can fetch water from following water inlet, very convenient.
Fig. 1 is the sectional structure chart of the utility model pipeline emptying device;
Fig. 2 is the structural representation of the emptying of the utility model band pipeline, automatic loading water.
The utility model is described in further detail below in conjunction with accompanying drawing.
Can see that by Fig. 1, Fig. 2 this water heater has heat collector, water tank (3), the bottom of water tank connects an emptying device (24), and it has a valve body (9), and valve body has the water inlet (2) of water flowing case, and the delivery port (6) of logical upper and lower water drives gas port (8) above into; One valve rod (1) is arranged in the valve body, be with spring (5) on this bar, an end of valve rod feeds the water inlet (2) of water tank, and cover one cuts down sheet (4) on the valve rod of water inlet; The other end of valve rod connects stressed plate (7), this plate has leather cup (10) outward, and the inlet plenum (11) of sealing is arranged in the outside of leather cup, and this chamber has from locking and hanging hook (13), pin (14) switch contact (12), air inlet (15), air inlet connects wireway (16) and air bag (18), and (17) are relief valve.
When needing exhausting pipeline winter, air inlet (8) is open, and leather cup (10) is in relaxed state, and spring is close to water inlet (2) with valve block, with it stifled on, open the water emptying that switch under the delivery port (6) just can make pipeline this moment.Close pressure relief opening and give the air chamber pressurising of sealing with hand pinching air bag, skin pea expansion displacement drives the displacement of spring and valve block, at this moment water inlet (2) is opened, water inlet (2) and delivery port (6) UNICOM can pass through the upper and lower water of delivery port (6), are in non-emptying state.To keep this position from the pin (14) of locking and hanging hook effect bottom offset for a long time, be suspended in the groove of locking and hanging hook (13), make valve block keep original position at air pressure.
Can see that by Fig. 2 this solar water heater is equipped with automatic water-supply apparatus, it has a secondary water tank (25), its position is higher than water tank (3), secondary water tank connects an automatic loading water pipe (27), this pipe is communicated with running water pipe, and the automatic loading water pipe connects a ball-cock assembly (26) in secondary water tank, in the secondary water tank, upperly have escape pipe (19) and filling pipe (20) to be communicated with water tank, upper vent (8) in emptying device (24) connects a water pipe (23), feeds the top of water tank.(21) be water-level probe, (22) are conduit.Spring and autumn and summer can be used automatic water-supply apparatus, and the water of its secondary water tank can add in the water tank at any time, by pipe (23), gas outlet (8), delivery port (6) water outlet, and also can be at non-emptying state by water inlet (2) and delivery port (6) water outlet.Close upper hose winter.
