Abstract

The invention relates to a rotary cutting valve with a long service life structure. The rotary cutting valve comprises a valve body with a plurality of channels, a valve head shell fixedly connected with the valve body through a threaded gland, a valve element base arranged in the valve head shell, and a valve element arranged between the valve element base and the valve body. The valve element comprises a first contact face and a second contact face which are opposite in direction. The first contact face makes sealing contact with the bottom face, located in the valve head shell, of the valvebody. The second contact face makes sealing contact with the supporting face of the valve element base. A connecting groove is formed inwards from the second contact face of the valve element so thatwhen the valve element rotates to the position where the valve element is matched with at least two channels of the valve body, the connecting groove enables the channels to communicate. According tothe rotary cutting valve, the liquid mixing risk caused by relative movement between the valve element and the valve body of the rotary cutting valve can be reduced, and the service life of the rotary cutting valve is prolonged.

Description

technical field [0001] The invention relates to a rotary cutting valve, which belongs to the field of mechanical and electronic equipment. Background technique [0002] Rotary cutting valve is a kind of valve used to control the on-off relationship of fluid. It changes the flow path connected to the valve body through the relative movement between the valve core and the valve body. During the working process of the existing rotary cutting valve products, the internal parts will be more or less worn, especially the relative movement between the valve core and the valve body will cause wear. Combined with the error of the machining accuracy of the parts themselves, after a period of use, the valve core and valve body will be severely worn and the sealing surface will be damaged, resulting in the failure of the sealing performance, thus affecting the service life of the product. [0003] In addition, the current rotary cutting valves on the market realize the switching of the ...
