Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the invention easy to understand, the invention is further explained below with reference to the specific embodiments, but the following embodiments are only the preferred embodiments of the invention, not all. Based on the embodiments in the embodiment, those skilled in the art can obtain other embodiments without making creative efforts, and all of them belong to the protection scope of the present invention. The experimental procedures in the following examples were carried out in a conventional manner unless otherwise specified, and materials, reagents and the like used in the following examples were commercially available unless otherwise specified.
Example (b):
referring to fig. 1, the downward-expanding type diverting baiting valve includes a downward-expanding type diverting baiting valve main body, a valve flap, a valve seat, a lengthened stuffing box, a valve rod and a driving device are sequentially disposed in the downward-expanding type diverting baiting valve main body, a main path pipeline is disposed at the upper end of the downward-expanding type diverting baiting valve main body, and a first branch pipeline and a second branch pipeline are disposed at the lower end of the downward-expanding type diverting baiting valve main body.
The surface of the main body of the downward-spreading type diversion discharge valve is sleeved with a heat-insulating jacket. The drive arrangement tip is provided with the valve rod, and runs through extension packing box and disk seat in proper order in the middle part of the valve rod, drive arrangement installs on extension packing box, extension packing box tip is installed on the disk seat, the disk seat tip is installed on under-expanding reposition of redundant personnel baiting valve main part, the valve clack is installed to the valve rod tip, and valve clack and the laminating of disk seat port.
