Abstract
A valve of the antifreeze solar water heater hot water emptying valve is arranged in an inner water tank of the solar water heater, the valve body is positioned in a heat insulation layer, a direct current micro speed reducing motor on the valve body drives a piston in the valve body to move, so that a tension spring connected with the piston moves up and down, a valve rod on the tension spring moves up and down to open and close the valve connected with the valve rod, an air inlet and exhaust channel is arranged in a valve cavity, when the valve is closed, air enters the valve cavity to empty excess water in the valve and a pipeline connected with the valve cavity, and the aim of preventing freezing and blocking is fulfilled. The utility model discloses compact structure, convenient operation, safe and reliable, the evacuation is thorough, is the frost-proof ideal emptying devices of present solar energy pipeline.
Description
The utility model belongs to mechanical field, is specifically related to a kind of structure of freeze-proof type solar hot water exhaust-valve.
The exhaust-valve that uses on the present solar water heater of China has manually and electronic two classes, and hand-operated valve has ball valve, stopcock, gate valve etc., and electronic have magnetic valve, pulse automatic valve, a controllable silicon exhaust-valve etc.Because the particularity of solar water heater installation site, it is outdoor that pipeline must be exposed to, if valve is contained in indoor, the upper and lower conduit road was easy to generate and froze stifledly winter, and to have solved freezing of pipeline stifled though be installed on outdoor controllable silicon exhaust-valve, but under certain cryogenic conditions, valve self can occur freezing stifled, though it is stifled to adopt electrically heated method that valve is not frozen to valve body, has increased user's expenses, security is bad, will wait to be heated thawing during use.At present still there is not a kind of valve that can solve again simple in structure to freeze stifled novel exhaust-valve.
The purpose of this utility model is: design a kind of freeze-proof type solar water heater hot-water exhaust-valve, it can solve the stifled problem of freezing of solar water heater emptying valve in winter effectively
The purpose of this utility model is achieved in that the valve body of packing between the inner water tank of solar water heater water tank and external thermal insulation, make valve be positioned at inner water tank, valve body is arranged in heat-insulation layer, the piston motion that miniature electrical machinery axle on the valve body drives in the valve body makes the extension spring that is connected with piston rise and descend, realize the keying of valve thereby make the valve rod that is positioned at extension spring top rise and descend, in valve, leave simultaneously intake and exhaust channel, when valve cuts out, the air that enters in the valve pocket can make water unnecessary in the valve through tube emptying, the pipeline that makes valve pocket and be attached thereto is ponding not, thereby solved the stifled problem of freezing of pipeline and valve.
Fig. 1 is the utility model structure cut-away view
Among the figure: 1 deceleration direct current generator, 2 screw mandrels, 3 valve seats, 4 core pipes, 5 valve bodies, 6 ports, 7 valves, 8 valve rods, 9 extension springs, 10 pistons, 11 air admission holes, 12 inner water tanks, 13 heat-insulation layers, 14 intake-outlets.
Further introduce the utility model implementation method below in conjunction with accompanying drawing:
Valve body 5 is positioned at the heat-insulation layer 13 of solar water heater storage water tank, its valve is positioned at inner water tank 12, intake-outlet 14 on the valve body is positioned at water tank heat-insulation layers 13 outsides, DC speed-reducing 1 is connected as a single entity with valve body 5, motor output shaft is a threaded screw mandrel 2, be with the piston 10 that matches with wire rod thread on it, piston 10 is positioned at the core pipe 4 of valve body 5, top land connects extension spring 9, the other end of extension spring 9 connects valve rod 8, valve rod 8 links to each other with valve 7, and valve body 5 one sides have intake-outlet 14, and an air admission hole 11 is arranged on valve seat 3.
When the hot water in the needs usefulness inner water tank, connect DC speed-reducing 1 power supply, direct current generator work, its output shaft 2 rotates, because axle 2 is a screw structure, its drives the piston 10 be enclosed within above it rises, and makes in the extension spring 9 on piston 10 tops to push away, and drives on the valve rod 8 that is positioned at extension spring 9 upper ends and moves, make on the valve 7 that is positioned on the valve rod 8 and push away, make valve 7 be in opening, the hot water in the inner water tank enters valve pocket from valve 7, uses for the user through pipeline from intake-outlet 14.
During ponding in needing emptying valve pocket and pipeline, as long as oppositely connect DC speed-reducing 1 power supply, make its backward rotation, at this moment output shaft 2 rotates, and it is descending to drive the piston 10 that is placed in above it, and the extension spring 9 on the piston 10 is drop-down, the valve rod 8 that is positioned at extension spring 9 tops is moved down, drive valve 7 and descend, valve 7 coincide with the sealing ring at valve port place, and valve is in closed condition.Water in the inner water tank 12 can not enter valve pocket, the air at air admission hole 11 places enters valve pocket through port 6 simultaneously, make the interior water of valve pocket under the effect of atmospheric pressure, discharge through intake-outlet, along with constantly entering of air will also be drained the water in the pipeline that is connected in intake-outlet 14, thereby realize air emptying function.
The utility model compact conformation, simple to operate, safe and reliable, emptying is thorough, is the desirable antifreeze emptier of present solar water heater.
