Water-outflow-angle-adjustable fire hydrant easy to maintain
The invention provides a water-outflow-angle-adjustable fire hydrant easy to maintain. A valve body is installed on an underground water pipe through a nonmetal flat gasket and a flat washer. A sealing valve assembly capable of being taken out as a whole is installed in the valve body. A water releasing valve assembly and the valve body are in threaded connection. A stainless steel snap ring is installed on a lower hydrant body and connected with the lower hydrant body through a lower hydrant body flange. An upper hydrant body and the lower hydrant body are connected into a whole through a first lower hydrant body flange, a first fragile flange and a second fragile flange. The upper hydrant body is provided with a water suction port connector and a water suction port connector cover. A lifting valve rod assembly is arranged on the upper portion of the upper hydrant body. The upper portion of the lifting valve rod assembly is covered with an upper cover. The lifting valve rod assembly, a lower anti-collision connector, a sealing valve connecting rod and the sealing valve assembly are connected together through hexagon socket cap screws, and therefore a sealing valve can be opened or closed. The water-outflow-angle-adjustable fire hydrant easy to maintain has the advantages that the fire hydrant is easy to detach and maintain, a water receiving port and the water outflow direction are adjustable, and the fire hydrant is anti-freezing. The water-outflow-angle-adjustable fire hydrant easy to maintain is suitable for being used as a fire hydrant.
