Description
Technical field
The utility model relates to water pump Auto-drainage control technique field, especially relates to a kind of water pump automatic drain valve.
Background technique
At present various water pumps, want during use in winter water in timely discharging pump, as not in time or forget draining, temperature lower than during subzero can because of freezing and expansion, damage pump equipment, manually lay down water blocking discharge water owing to all adopting at present, operate cumbersome, the accident of freezing water pump, pipeline, valve happens occasionally, and causes great economic loss to user.
Summary of the invention
The purpose of this utility model is, causes freezing water pump not in time for current water pump behaviour in service, draining in winter, affects the phenomenon of producing, bringing economic loss, and a kind of water pump automatic drain valve provided.
The utility model solves the technological scheme that its technical problem adopts, adopt copper bellows temperature-sensitive bag, inner perfusion freon liquid, utilizes temperature to reduce the principle of volume shrinkage, when temperature is close to zero degree, temperature-sensitive bag shrinks, compressed the needle-valve of drain opening by the release of interlock lever, the water in water pump shell was discharged before freezing, the freezing water pump of making ice, the utility model is by valve body, shell forms, and valve body upper end is the interface connecting pumping drainage screw, and lower end is draining connection mouth, enclosure cross setting needle-valve body, there is the needle-valve push rod of band button, by valve rod spring, by manually advancing, close drain valve, now valve rod is pinned by valve rod lock banking stop, the water of water pump can not outflow, when mercury dropped is to zero degree, temperature-sensitive bag shrinks, pull interlock lever, interlock lever pushing lock banking stop is descending, departs from needle-valve push rod lock groove, needle-valve push rod discharges return under the effect of return spring, needle-valve is opened, moisture in water pump is discharged, and the temperature control point of temperature-sensitive bag is determined by the adjustment of temperature-sensitive adjusting screw, and the utility model adopts brass or stainless steel manufacture.
The beneficial effects of the utility model are: can automatically discharge water pump moisture in time, conscientiously ensure that equipment normally runs and safety according to temperature decline owing to have employed, the utility model is applied widely, be applicable to multiple water pump and need automatically to discharge winter other equipment of moisture, esy to use, safe and reliable.
