Description

Anti-false-opening valve with lock

Technical Field

The utility model belongs to the technical field of the valve is made, a take lock to prevent mistake and open valve is related to.

Background

The ball valve is a valve which uses a ball body with a circular through hole as an opening and closing part, the ball body moves along with a valve rod to realize the opening and closing actions, and the opening and closing part of the ball valve is a ball body with a hole and rotates around an axis vertical to a channel, so that the aim of opening and closing the channel is fulfilled. Ball valves are used primarily for opening and closing pipes and equipment media.

The application range of the ball valve is very wide, especially in chemical plants, and a plurality of chemical raw materials are conveyed through pipelines and then are controlled to be fed through the ball valve. Very most chemical plant can use when carrying out the large-scale production to throw the storage bucket or throw the skip and throw the material, often takes place to throw the storage bucket or throw the skip and open the valve, and in addition the raw materials has certain buffering from the pipeline to the valve, can not discover the weeping at once when just opening the valve by mistake, after discovering the weeping to and cause very large tracts of land to reveal, not only cause the waste of raw materials, more can bring the potential safety hazard.

For example, chinese patent literature discloses a lock-controlled ball valve [ application number: 201420761195.7, respectively; authorization notice number: CN204312756U ], which comprises a cylindrical valve body having a neck, a valve core and a valve rod are arranged in the valve body, and an O-ring is arranged on the outer edge of the outer end of the valve rod, which extends out of the neck and cuts the inner end of the valve rod. The valve core is characterized in that a socket is formed in the outer side wall of the valve core, the inner end of the valve rod is spliced in the socket, the valve rod drives the valve core to rotate, a strip-shaped lock hole penetrates through the inner end of the valve rod in the radial direction, magnetic poles at two adjacent ends of a magnetic column and two magnetic columns are spliced at two ends of the lock hole respectively, positioning holes corresponding to the positions of the lock holes are formed in two sides of the neck respectively, the other ends of the two magnetic columns are spliced in the corresponding positioning holes respectively, a power part enabling the two magnetic columns to have opposite stable trends is arranged in the neck, and a limiting groove enabling the O-shaped ring to be clamped in when the valve.

Although the lock-control ball valve can ensure that the abnormal opening and closing of the valve caused by the rotation of the handle due to other factors can not be caused under the condition of manually unlocking, the lock-control ball valve is relatively troublesome to use, the valve rod is locked after the valve is used, the valve rod is opened and locked when the valve is used, and once the valve is busy, the lock can not be locked directly at many times, so that the shape of the lock is the same as that of the nominal lock.
