Problems solved by technology
The structure of the traditional reversing valve is relatively simple, so it is necessary to set up multiple water channels to guide the water flow into the filter element for filtering or guide the water flow to clean the filter element, resulting in intricate water flow channels inside the filter and high production costs; at the same time, the traditional filter element The cleaning method is easy to leave impurities, which will easily cause the filter element to be not cleaned cleanly

Embodiment Construction
[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0034] It should be noted that when an element is referred to as being “fixed on”, “disposed on”, or “installed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The specific manner in which one element is considered to be "sealedly connected" to another element can be realized through existing technologies, and will not be repeated...

The invention relates to a valve core and a reversing valve. The valve core comprises a valve body, a first connector and a second connector, wherein the first connector and the second connector are oppositely arranged and are fixed to the two sides of the valve body separately; the valve body is provided with a first inlet-outlet; the first connector is provided with a second inlet-outlet; and a first channel which communicates with the first inlet-outlet and the second inlet-outlet is arranged between the valve body and the first connector. According to the valve core and the reversing valve, a water current is easily guided to enter a filter element to be filtered or to clean the filter element, the flow direction of the water current in a filter is more reasonable, assembly is easy, and production cost is reduced; and water can be sprayed outwards from the filter element during cleaning, and the filter element is cleaned more thoroughly.
Description
technical field [0001] The invention relates to the technical field of pipeline reversing equipment, in particular to a valve core and a reversing valve. Background technique [0002] At present, the filter is installed at the front end of the pipeline for filtering and purifying water. The filter needs to be switched to clean the filter element through the reversing valve. The structure of the traditional reversing valve is relatively simple, so it is necessary to set up multiple water channels to guide the water flow into the filter element for filtering or guide the water flow to clean the filter element, resulting in intricate water flow channels inside the filter and high production costs; at the same time, the traditional filter element The cleaning method is easy to leave impurities, and it is easy to cause the filter element to not be cleaned cleanly. Contents of the invention [0003] Based on this, it is necessary to provide a valve core and a reversing valve, ...
