Description

Flow-blocking type eccentric half ball valve for slurry Technical Field The utility model relates to the technical field of eccentric hemispherical valves, in particular to a choked flow type eccentric hemispherical valve for slurry. Background The flow-blocking type eccentric half ball valve for slurry is a valve designed specially for slurry and other solid-containing and high-viscosity media, and can realize efficient cutting-off, adjusting and flow-blocking functions through the unique design of an eccentric structure and a hemispherical valve core. During the opening process, the valve core is separated from the valve seat to avoid friction and wear, and during closing, the valve core is gradually pressed against the valve seat to realize zero leakage through the metal-metal or metal-nonmetal sealing pair. For slurry media, the surface of the spool is typically hardened (e.g., hard-metal overlay) or sprayed with a wear-resistant coating to resist particle washout. Because more solid particles exist in the slurry, in the long-term use process, the solid particles are easy to abrade the valve seat, so that the sealing performance of the valve seat is reduced, the service life is shortened, and the valve seat is required to be maintained and replaced regularly. However, the valve seat of most of the existing choked flow type eccentric semi-ball valves is fixedly arranged in the valve body, so that the valve seat is complicated in mounting and dismounting, and the valve seat is inconvenient to maintain and replace in daily life. Disclosure of utility model The utility model aims to provide a choked flow type eccentric half ball valve for slurry, which solves the problems that most valve seats of the choked flow type eccentric half ball valves are fixedly arranged in a valve body, so that the valve seats are complicated in mounting and dismounting, and the daily maintenance and replacement are inconvenient. The flow-blocking type eccentric half ball valve for slurry comprises a valve body and flange seats fixedly connected to two sides of the valve body, wherein one flange seat is provided with a valve seat unit; The valve seat unit includes: a valve seat assembly, the valve seat assembly comprising: The valve seat body is positioned in the valve body; the plug-in ring block is fixedly connected to one side of the valve seat body; The mounting seat is arranged on one side of the plugging ring block, the plugging ring block is plugged in the mounting seat, and the mounting seat is connected in the flange seat in a sliding manner. Preferably, the valve body is rotatably connected with a valve core, the valve core is C-shaped, and the valve core is abutted against the valve seat body. Preferably, the top fixedly connected with valve gap of valve body, the valve gap is provided with sealed packing, the valve gap swivelling joint has the valve rod, the bottom and the case fixed connection of valve rod. Preferably, the bottom of valve body fixedly connected with base, the base rotates with the case bottom to be connected. Preferably, the top of the valve rod is fixedly connected with a switch turntable. Preferably, a limiting block is fixedly connected to the inner side of the flange seat, and a clamping groove is formed in the limiting block. Preferably, the valve seat assembly further comprises a fastening bolt, the bottom end of the fastening bolt penetrates through the plug-in ring block, and the fastening bolt is in threaded connection with the plug-in ring block and the mounting seat respectively. Preferably, the mounting seat is provided with an annular groove, and the annular groove is movably inserted with the insertion ring block. Preferably, the mounting seat is provided with a sealing gasket, and the sealing gasket is in extrusion clamping connection in the clamping groove. Compared with the prior art, the utility model has the beneficial effects that: 1. This a choked flow formula eccentric half ball valve for mud is through adopting plug-in type structure, and the grafting ring block is pegged graft in the mount pad, and mount pad sliding connection is in the flange seat, and rethread pipeline ring flange extrudees fixedly. When the valve seat needs to be replaced, the mounting seat is only required to be pulled out of the flange seat, the valve seat body can be taken out of the mounting seat by unscrewing the fastening bolt, so that the valve seat assembly is replaced more quickly and conveniently, the whole valve is not required to be disassembled, the maintenance time is greatly shortened, and the maintenance cost is reduced. 2. This a choked flow formula eccentric half ball valve for mud extrudees joint in the draw-in groove through sealing washer, has further strengthened the leakproofness between disk seat unit and the flange seat, has improved the whole sealed effect of valve.
