Problems solved by technology

In the process of controlling the opening and closing of the valve, the spherical or round pie-shaped spool needs the spool to rotate around the valve stem in the valve cavity as a whole, that is, the spool moves in a circle, which will cause the entire valve structure to be too large. Huge, making the valve body larger in volume and weight

Abstract

The invention discloses a valve which comprises a valve body (1). A valve cavity (2) is formed in the valve body (1). A passageway (3) is arranged in the valve cavity (2). A support (4) is arranged on the valve body (1). A threaded rod (5) is screwed in the support (4). One end of the threaded rod (5) is connected with a handle (6) outside the valve cavity (2). The valve further comprises two valve blocks, wherein the valve blocks rotate around a hinged shaft fixed in the valve cavity (2) so as to open or close the passageway (3). The other end of the threaded rod (5) is connected with a guide column (7) which is in sliding fit inside the support (4). Locking blocks (8) which are used for pressing the upper ends of the two valve blocks so as to fold the two valve blocks together and can stop limiting the two valve blocks are arranged at the lower portion of the guide column (7). An elastic device which is used for pulling the two valve blocks to rotate so as to open the passageway (3) is arranged in the valve cavity (2). The valve is small in size and light in weight.

Description

technical field [0001] The invention relates to a valve, in particular to a valve for controlling flow. Background technique [0002] At present, the structure of the valve includes a valve body, a valve cavity is arranged in the valve body, a valve core is installed in the valve cavity, and a valve stem is connected to the valve core. The valve stem drives the valve core to rotate, driving the valve to open and close. Among them, the spool is the main component of valve flow control, and is the core component of opening and closing the valve. The shapes of the spool are: spherical, conical, round pie, cylindrical and so on. However, when the valve is used in large-diameter pipeline connections, the size of the spool is determined by the caliber of the pipeline, that is, the size of the spool needs to be as large as the caliber of the pipeline. In the process of controlling the opening and closing of the valve, the spherical or round pie-shaped spool needs the spool to ro...
