Abstract
The utility model belongs to a valve for discharging the water in the pipeline in the water tank of the solar water heater and the roofing water storage tank on the house. Because of the fact that the freezing and blocking phenomenon appears in the pipeline of the solar energy water heater and the water storage tank when the winter temperature is below the zero degree Celsius, the freezing and blocking problem can not be solved through the existing methods, the pipeline is easy to damage, and the repair expense of the pipeline is high. The utility model comprises a valve body, a sliding valve core and a one-way air inlet; the internal wall of the valve body is provided with an annular tooth socket; the sliding valve core is arranged in the valve body, and the sliding valve core is provided with a convex column arranged in the annular tooth socket. The alternating motion of the valve core is used to control the opening and closing of a valve mouth, and the valve wall between the valve mouth and a discharge valve is provided with the one-way air inlet. The utility model having stable property is uneasy to damage, can discharge conveniently the water in the pipeline of the solar energy water heater and the water storage tank, and is the valve for discharging water in the pipeline of solar water heaterand for solving the freezing and blocking phenomenon thoroughly.
Description
Affiliated technical field
The utility model belongs to a kind of mechanical valve, particularly solar water heater water tank and housing roof water storage box pipe evacuation control valve.
Background technique
China town and country use the unit of solar water heater and housing roof water storage box and family to get more and more at present, yet in use, there is a problem always perplexing users, be that winter temperature is when being lower than zero degree, the pipeline of solar water heater, water storage box has and freezes stifled phenomenon, in case be frozen to block, the user just can't water.The method that stifled phenomenon is frozen in existing solution has two kinds: (1) adds the cover thermal insulation layer at pipeline outer wall, increases heating tape, makes to exist thermal insulation layer, heating tape easily aging in this way, when outdoor temperature is extremely low, can't better solves and freeze stifled problem; (2) adopt electron tube evacuating pipeline method, this method exists electronic component fragile, inconvenient maintenance, the defective that expense is high.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of stable performance, not fragile, and drain-solar water heater, the ducted water of water storage box thoroughly solve the pipeline emptying valve for solar water heater that freezes stifled phenomenon easily.
For achieving the above object, technical solution of the present utility model is: pipeline emptying valve for solar water heater comprises valve body, sliding valve core, and it also comprises unidirectional suction port.Set up annular groove on valve interior wall one, the two side of groove is a zigzag fashion, and the number of teeth is identical even number, crown relatively and staggered, the serrated teeth paddy at every interval place axially has approaching channel along valve body on the groove walls of valve port side.Sliding valve core places in the valve body, and sliding valve core is provided with one or several projections, and projection places in the annular groove, and when projection moved in annular groove, valve port was the unlatching shape, and after projection entered approaching channel, valve port was closed gradually.On the valve wall between valve port and the exhaust-valve opening, unidirectional suction port is set.
The technological scheme of setting up one annular groove on the valve interior wall be in valve body by the water heater one side valve body commutating tooth inwall that closely cooperates, the anti-tooth inwall of tube road one side transition fit valve body in valve body, valve body commutating tooth inwall and valve body can be designed to one and process.
The utility model sliding valve core moves reciprocatingly in valve body, and owing to the projection on the sliding valve core is stuck in the annular groove, and the two side of groove is a zigzag fashion, and the number of teeth is identical even number, crown is relative and staggered, so the every to-and-fro motion of sliding valve core once, all will rotate lattice along the sawtooth wall.When projection moved in annular groove, valve port was the unlatching shape, and solar water heater, water storage box pipeline can be realized upper and lower water; After projection entered approaching channel, valve port was closed gradually, and open the effluent switch that is connected with pipeline this moment, made pressure reduction in the pipeline, and unidirectional suction port is promptly opened automatically, can realize pipe evacuation.
The utility model has the advantages that: stable performance, not fragile, drain-solar water heater, the ducted water of water storage box thoroughly solve the pipeline emptying valve for solar water heater that freezes stifled phenomenon easily.
