Embodiment 1

[0009] Embodiment 1: Embodiment 1 of the present invention—multiple sets of synchronous rotary plug valves are used for the intake and exhaust valves of a four-cylinder internal combustion engine. The schematic diagram of its plug body structure can be found in figure 1 The plug body of the epicyclic plug valve in this embodiment is a solid body with a rectangular through hole through the center. The shadowed rectangle in the figure indicates a through hole on one side of the plug body. The four rectangular through holes on the side are representative. The plug body of a multi-pair synchronous epicyclic plug valve used for one-cylinder to multi-cylinder internal combustion engine valves has one, two, three, four or more plug body through-holes, which can be connected with each other on the same radial section. Two, four, six, eight or more valve body through holes and the valve body forming the opening and closing action form an opening and closing pair, corresponding to the ...

Abstract

The invention relates to a plug valve. A cylindrical plug body or a conical plug body does unidirectional turnover movement other than reciprocating rotation relative to the valve body; in relative turnover, an opening-closing pair is formed by the plug body and through holes of the plug body which are capable of mutually forming opening-closing movement on the same radial-direction cross sectionand the valve body and through holes of the valve body which are capable of mutually forming opening-closing movement on the same radial-direction cross section, the opening-closing pair can form periodic opening-closing movement in turnover, and is used for periodic opening-closing control of fluid, and the turnover-type plug valve can have one or more opening-closing pairs. The turnover-type plug valve can also be designed to a multi-pair synchronous turnover-type plug valve and a distribution turnover-type plug valve.

Description

technical field [0001] The invention relates to a fluid valve, in particular to a plug valve with one-way rotation of the plug body. Background technique [0002] In order to improve the performance of the valve, different valves should be used according to different engineering needs. The existing plug valve is a kind of valve which realizes the opening and closing function by the reciprocating movement of the conical plug body or the cylindrical plug body, and has a simple structure, which is not conducive to periodic opening and closing. The object of the invention is to propose a novel plug valve which is convenient for periodic opening and closing. Contents of the invention [0003] The epicyclic plug valve proposed by the present invention is a new type of plug valve, which includes a cylindrical plug body or a conical plug body, a valve stem, a valve body, etc., and both the plug body and the valve body are provided with through holes. The feature is that the plug...
