Description

Stop valve for pipeline Technical Field The utility model relates to the technical field of stop valve equipment, in particular to a stop valve for a pipeline. Background The stop valve is used as an important opening and closing control device in a pipeline system, and the valve rod drives the valve clack to realize linear opening and closing of a medium channel, so that the valve has the characteristic of excellent sealing performance. The traditional household stop valve generally adopts a hand wheel driving structure, the diameter of a hand traditional hand wheel is generally designed to be 80-100mm, and a valve rod thread pair is driven to move by rotating the hand wheel, so that the displacement of a valve clack is controlled. In actual use, sometimes the resistance is great when needing to open the stop valve from the closed state, and female user often runs into the condition that the operation is blocked hard, sometimes wants to close the stop valve fast and throttles, and every time needs 4-5 times of screwing of hand to realize 360 degrees rotations, and closes the stop valve often and need 8-10 circles, inefficiency. Disclosure of utility model The utility model aims to provide a stop valve for a pipeline, which solves the problems in the prior art. In order to achieve the above purpose, the present utility model adopts the following technical scheme: A stop valve for a pipeline comprises a valve body with a built-in valve clack, a valve rod which drives the valve clack to lift through threaded connection, a valve cover which is arranged on the upper part of the valve body and is in sealing connection with the valve rod, and a manual execution assembly which drives the valve rod to rotate. The top of the valve rod comprises an external thread column, a square head column and a limiting rod body from top to bottom. The manual execution assembly comprises a starting hand wheel, a limit post, an execution hand wheel and a locking nut, wherein the starting hand wheel is in limit sleeving connection with a square head post, the limit post is in limit sleeving connection with the square head post, the execution hand wheel is in limit sleeving connection with the square head post, the locking nut is in matched connection with an external thread post, the limit post is provided with a limit square head through hole matched with the square head post, the starting hand wheel comprises a first rim, a first spoke and a first hub, a first square head through hole matched with the square head post is arranged in the center of the first hub, the upper end face and the lower end face of the first hub are in limit butt joint with the bottom end of the limit post and the top face of a limit rod body respectively, the execution hand wheel comprises a second rim, a second spoke and a second hub, the second hub comprises a second square head through hole matched with the square head post and an auxiliary rotation execution part fixedly arranged on the top face of the second hub, and the upper end face and the lower end face of the second hub are in limit butt joint with the bottom face of the locking nut and the top face of the limit post respectively.
