Detailed Description

In order to make the technical field personnel understand the utility model discloses the scheme, will combine the drawing in the embodiment of the utility model below, to the technical scheme in the embodiment of the utility model carries out clear, complete description.

As shown in fig. 1-4, the anti-misoperation combined valve comprises a valve pipe 10 which is arranged in a hollow manner, wherein the outer peripheral side of the valve pipe 10 is fixedly connected with a connecting block 11, a valve rod 15 is arranged in the connecting block 11, a valve cap 12 is arranged on one side, away from the valve pipe 10, of the valve rod 15, a disc plate 14 is fixedly connected on one side, away from the valve cap 12, of the valve rod 15, and a pull rod assembly is further sleeved on the valve rod 15;

the pull rod assembly comprises a pull rod 13, a through sliding hole is formed in the pull rod 13, an anti-slip sleeve wraps one side, away from the sliding hole, of the pull rod 13, friction force of the pull rod 13 can be increased, sliding is avoided when the pull rod 13 is pulled, a limiting rod 17 is fixedly connected to the inner wall of the sliding hole of the pull rod 13, a synchronizing block 16 is connected to the sliding hole in a sliding mode, the synchronizing block 16 is located between a valve cap 12 and a connecting block 11, the diameter of the valve cap 12 is larger than the width of the sliding hole, the synchronizing block 16 is sleeved on a valve rod 15, a sliding groove is formed in the end face, close to the limiting rod 17, of the synchronizing block 16, the limiting rod 17 is located in the sliding groove, at least two limiting cavities 18 are formed in the outer peripheral side of the position, located on the synchronizing block 16, two springs 19 are fixedly connected between the end face, away from the limiting rod 17, of the synchronizing block 16 and the inner wall of the sliding hole, the limiting cavities 18 are arranged in a central circumferential direction of the central line of the valve rod 15, the limiting cavities 18 are larger than the width of the limiting rod 17, and the limiting rod 17 and the springs 19 are arranged, misoperation of operators can be avoided, and accordingly, and the phenomenon that excessive or insufficient supply of media in pipelines is caused by the excessive supply of the media in the pipelines is caused.
