Abstract
The utility model discloses a hand rotary freezeproof water plug which belongs to a freezeproof technique for running water conveying pipelines. As a present freezeproof device arranged on the outdoor running water conveying pipelines has a complicated structure, easy damage, difficulties in operation and maintenance, and poor freezeproof effect in winter. The hand rotary freezeproof water-plug is characterized in that a water inlet hole and a water drain hole are arranged on a conical plug sleeve, wherein, an angle of 80DEG is arranged between the two holes, and the water inlet hole and the water drain hole are arranged at the one third point of the conical plug sleeve. A water outlet pipe and a return water pipe which are connected with a hollow conical plug core are twist grips, and a conducting hole is arranged at the center point of the hollow conical plug core. The closing of the underground water plug can be controlled by hands above the ground, and the water above the bottom line of the water inlet hole is drained. The hand rotary freezeproof water plug has the advantages of convenient operation, low cost and good freezeproof effect.
Description
The utility model belongs to tap water aqueduct freezing proof technique.
At present, the defroster that is installed on the outdoor tap water aqueduct mostly is wheel shank type water bolt, foot-operated water bolt, and weak point is a complex structure, and is fragile, is difficult for Operation and maintenance, the preventing freeze in winter weak effect.
The purpose of this utility model is to provide a kind of simple in structure in the weak point of avoiding above-mentioned technology, easy operating and maintenance reach more than 15 years application life, and closing with hand control underground water bolt on the ground, and bottom line above water in inlet opening drained, play desirable antifreeze effect.
This unfreezable tap is by going out return pipe (1), clamp nut (2), conical hollow bolt core (3), tapered plug cover (4), inlet opening (5), spilled water hole (6), locating slot (7), dog screw (8), via (9), constituting.It is characterized in that: a. has inlet opening (5) and spilled water hole (6) on tapered plug cover (4), and two holes are at a distance of 80 °.B. inlet opening (5) and spilled water hole (6) are at last 1/3rd places of tapered plug cover (4).C. joining to go out return pipe (1) be rotary handle with conical hollow bolt core (3).D. have via (9) on conical hollow bolt core (3) central point.
Structure of the present utility model is shown in accompanying drawing (structural representation).With hand clockwise rotate with conical hollow bolt core (3) on be connected go out (1) 80 ° of return pipe, the qualification groove (7) of tapered plug cover (4) lower end is limited by the dog screw (8) of hollow tapered plug core (3) lower end, inlet opening (5) conducting on via (9) on conical hollow bolt core (3) sidewall and tapered plug cover (4) sidewall, and spilled water hole (6) is sealed by the another side of conical hollow bolt core (3), and this moment, the water bolt was in running order.
With hand rotate counterclockwise with conical hollow bolt core (3) on be connected go out (1) 80 ° of return pipe.The qualification groove (7) of tapered plug cover (4) lower end is limited by the dog screw (8) of conical hollow bolt core (4) lower end, spilled water hole (6) conducting on via (9) on conical hollow bolt core (3) sidewall and tapered plug cover (4) sidewall, and inlet opening (5) are sealed by the another side of conical hollow bolt core (3), bottom line above water in inlet opening (5) drains, at this moment, the water bolt is in closed condition.
The utility model compared with prior art, it is little, simple in structure to have a volume, honest and clean at the bottom of the cost, uses light and the life-span is long, has open and close and antifreeze three effects.
Claims (1)
1, a kind of manual swinging unfreezable tap is by going out return pipe (1), clamp nut (2), conical hollow bolt core (3), tapered plug cover (4), inlet opening (5), spilled water hole (6), locating slot (7), dog screw (8), via (9) formation.It is characterized in that:
A. on tapered plug cover (4), have inlet opening (5) and spilled water hole, and two holes are at a distance of 80 °;
B. inlet opening (5) and spilled water hole (6) are at last 1/3rd places of tapered plug cover (4);
