Pipe position locking mechanical valve

Abstract

The invention discloses a pipe position locking mechanical valve. The pipe position locking mechanical valve comprises a valve body neck part, a valve body, a valve part and a hand wheel; the right side of the hand wheel is connected with a fixed pipe sleeve; the hand wheel is connected with the fixed pipe sleeve through a hand wheel shaft; a movable disc is mounted on the right side of the fixed pipe sleeve; the right side of the movable disc is connected with a fixed disc; a fixed ring is arranged on the right side of the fixed disc; a flange is mounted on the lower side of the fixed ring; the valve body neck part is arranged below the flange; the valve body is connected below the valve body neck part; a valve ring is embedded in the valve body, and is provided with a plug column; the valve part is embedded in the valve ring; a valve element is mounted in the valve part; the inner side of the hand wheel is connected with a hand wheel support rod; and the tail end of the hand wheel support rod is connected with a hand wheel rotating core. The movable disc is higher than the fixed pipe sleeve; the flange and the valve body neck part are connected integrally; the movable disc and the fixed disc are produced by stainless steel metal; and the hand wheel support rod and the hand wheel are fixedly connected. The pipe position locking mechanical valve has the following advantages: the improved valve body is low in production cost, convenient in production, high in rotary positioning precision and the like.

Description

technical field [0001] The invention relates to a mechanical pipeline valve, in particular to a position-locking mechanical valve for pipelines. Background technique [0002] The valve has the advantages of small fluid resistance, compact structure, reliable sealing, convenient operation and simple maintenance, so it is widely used in petroleum, chemical industry, power generation, aviation and plumbing, etc. Conventional butterfly valve has simple structure, small size, light weight and small installation size , The driving torque is small, the operation is simple and fast, although the performance stability is not as good as that of ball valves and gate valves, but the cost is low and the cost performance is high, so it is widely used; [0003] At present, the working principle of the butterfly valve is to rely on the valve core to rotate 90° to realize the opening and closing of the flow channel, while the valve core is always affected by the force of the water flow.
