1) Field of the Invention
The present invention relates to an improved ceramic valve for antifreezing faucets, in which a pair of double-plate ceramic intake valves, including disc-shaped top and bottom ceramic valve plates with some maximal big semicircular effluent holes, are designed. And the side of bottom section of a shaft bolt extends downwards to form a pair of symmetrical hack levers whose inside bottom has a concaved buckling part, so as to form linked control with the symmetrical position groove at the side of top ceramic valve plate; in addition, because the upper section of the hack levers is hollow-out and both sides form a wide and open effluent part, the effects of augmented effluent water and reduced block can be obtained, that is, it can ease the water's freezing and block at the water intake.
2) Description of the Prior Art
Generally, the conventional antifreezing faucet for outside ground mainly is designed and installed for outdoors water getting and watering conveniently. Nevertheless, the conventional antifreezing faucet (as shown in
Because of the foregoing ceramic valve's small effluent holes 2521, that is, only ¼ circular diameter, the effluent water W is limited. It fails to meet the demands for a large amount of water or high flow in the case of sprinkling large area and further places; particularly, in the frigid zone or some areas where the water easily freezes for the low temperature in the winter, it is easier that the water W will freeze at the small effluent holes 2521, more seriously block the faucet, accordingly, that will cause inconvenience and make waste. Therefore, this problem should be solved.
The main purpose of the present invention is to provide an improved ceramic valve for antifreezing faucets, in which a pair of double-plate ceramic intake valves, including disc-shaped top and bottom ceramic valve plates with some maximal big semicircular effluent holes, are designed. And the side of bottom section of a shaft bolt extends downwards to form a pair of symmetrical hack levers whose inside bottom has a concaved buckling part, so as to form linked control with the symmetrical position groove at the side of top ceramic valve plate; in addition, because the upper section of the hack levers is hollow-out and both sides form a wide and open effluent part, the effects of augmented effluent water and reduced block can be obtained, that is, it can ease the water's freezing and block at the water intake.
Another purpose of the present invention is still to provide an improved ceramic valve for antifreezing faucets, which is to be designed as a double-plate ceramic intake valve comprising equal disc-shaped top and bottom ceramic valve plates. It can reduce difficulties in manufacturing the valve and improve preparation precision. In addition, because the surface of the two ceramic discs is even, it can supply or shut off water stably.
Referring to
Both the top and bottom ceramic valve plates 51 and 52 of the intake ceramic valve are equal disc-type ceramic valve, on which the maximal semicircular effluent holes 511, 521 are designed, so as to conduct the overall alignment (as shown in
The side of bottom section of the shaft bolt extends downwards to form a pair of symmetrical hack levers 421; in which the inside bottom 421 of the hack levers 421 has a concaved buckling part 4211 respectively, which may be embedded into the position groove 512 at the side of top ceramic valve plate 51 to form linked control, further the upper side of the top ceramic valve plate 51 is hollow-out and both sides form wide and open an effluent part 4A while finishing the combination of the upper section of the hack levers 421 (please refer to
Moreover, because of big semicircular effluent holes 511 and 521 designed on the top and bottom ceramic valve plates 51, 52 and the big open effluent part 4A at the top side, the effects of augmented effluent water and reduced block would be obtained, so as to effectively prevent block for the frozen water at the water intake and enhance its antifreezing function actively.
