A rotary water supply valve

Abstract

The invention provides a rotary water supply valve. The rotary water supply valve is provided with a valve body, a valve element and a valve rod; and the water inlet end of the valve body is connected with a valve seat through a connecting ring, and rotation between the valve body and the valve seat is achieved through balls. The connecting ring is provided with an upper connecting ring body, a lower connecting ring body and a step face, the outer diameter of the upper connecting ring body is smaller than the outer diameter of the lower connecting ring body, and the step face is formed between the upper connecting ring body and the lower connecting ring body. A groove is formed in the step face, the balls are contained in the groove, and therefore rotation of the water valve is achieved. The upper connecting ring body is sleeved with an upper sealing ring, and the lower connecting ring body is sleeved with a lower sealing ring. A baffle, a spring and a valve block are arranged in the water outlet end of the valve body, and the spring is arranged between the baffle and the valve block. After the structure is adopted in the rotary water supply valve, the balls are arranged on the step face, so that rotation is achieved, and oneness and fixation of the traditional water supply valve direction are overcome. Meanwhile, the water flow is controlled through a water outlet hole of the valve block, and the water pressure is controlled through the spring.

Description

technical field [0001] The invention belongs to the technical field of pipelines, and in particular relates to a water valve. Background technique [0002] In the common water supply system in life, the water inlet and outlet of the water supply valve are at a fixed angle, generally 90° angle or 180° straight-through type. The water inlet pipe and the water outlet pipe are usually hard metal water supply pipes. After the water inlet end is connected with the water inlet pipe, and the water outlet end is connected with the water outlet pipe, the water flow direction of the water supply system is just fixed. Due to the singularity and fixity of the water flow direction, the range that the water supply system can serve is very limited. [0003] In order to be able to improve the range of water supply, a hose, such as a fire hose, has appeared on the market. Because the hose has the characteristics of easy bending and good ductility. Therefore, when the hose is connected to ...

However, in use, it will also be found that the rotation angle of the hose is limited, and the process of pulling the hose is relatively laborious, and the hose is easily damaged by repeated rotation and pulling.
