The invention provides a coaxial rotary valve. The coaxial rotary valve comprises a valve body, a valve cavity is formed in the valve body, a first valve hole and at least one second valve hole are formed in the valve body, a valve element is rotationally connected in the valve cavity, an element hole of the valve element is coaxially communicated with the first valve hole, and the diameter of the element hole is larger than or equal to the diameter of the first valve hole. According to the coaxial rotary valve, the diameter of the element hole is larger than or equal to the diameter of the first valve hole, the inner wall of the element hole and the inner wall of the first valve hole are made in the same plane, or the inner wall of the element hole is located on the outer side of the inner wall of the first valve hole, so that granular and / or flocculent dirt in fluid is prevented from easily entering the space between the valve element and the valve body, and the problem of blocking caused by dirt is avoided.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a coaxial rotary valve. Background technique [0002] Existing small electric three-way valves are mainly electric ball valves. The electric ball valve includes a valve body, a spherical valve core is installed in the valve body, and the valve core and the valve body are sealed and connected by a sealing ring. A deceleration motor is connected to the spool, and the deceleration motor drives the rotation of the spool to realize the opening and closing or reversing of the electric ball valve. Due to the limitation of the structure of the existing electric ball valve, the granular and / or lint-like dirt in the fluid easily enters between the sealing ring and the valve body during use, causing fouling. Contents of the invention [0003] A brief overview of the invention is given below in order to provide a basic understanding of some aspects of the invention. It should be understo...
