The invention relates to an assembly with a valve joint. The assembly comprises a valve body, a ball core and the joint, the valve body comprises an outlet cavity, a ball core cavity and an inlet cavity which communicate in sequence, the ball core is placed in the ball core cavity and is rotatably connected with the valve body, the joint is inserted into the outlet cavity to be connected with thevalve body, the outlet cavity is matched with the joint, the joint is provided with a joint cavity, the ball core is provided with a through hole, the joint cavity communicates with the through hole when the valve is opened, the arc face matched with the ball core is arranged at the connecting position of the joint and the ball core, the joint is provided with a groove, a hook-shaped clamping bodyon the ball core can be inserted into the groove, and the joint is fixed. Compared with the prior art, the assembly has the advantages of being rapid in dismounting, mounting and replacing, compact in structure, high in safety, few in part, high in reliability and the like.
Description
technical field [0001] The invention relates to the field of ball valves, in particular to a joint assembly with a valve. Background technique [0002] The ball valve came out in the 1950s. With the rapid development of science and technology, the continuous improvement of production technology and product structure, in just 40 years, it has rapidly developed into a major valve category, occupying an important position in the national economy. pivotal position. There are many types of ball valves, including floating ball valves, fixed ball valves, elastic ball valves, V-shaped ball valves, three-way ball valves, and eccentric ball valves. These ball valves often include a valve body, a ball, a seat seal, packing, a valve stem, a packing gland and a handle (or other driving device), wherein the valve body can be integral or combined. The working principle of these ball valves is the same: with the help of the handle (or other driving device), a certain torque is applied to ...
