Abstract

The invention discloses a valve part locking device which comprises an adjusting rod and a locking base. One end of the adjusting rod and an operation shaft pin of a valve part are detachably connected. The adjusting rod can drive the operation shaft pin to rotate. The locking base is used for selectively limiting rotation of the adjusting rod. According to the valve part locking device, the adjusting rod and the operation shaft pin of the valve part are detachably connected, the valve part and the valve part locking device are arranged and installed separately, the manner is different from the manner of fixedly connecting the valve part and the valve part locking device in a unified manner before the valve part leaves the factory in the prior art, the valve part locking device can be additionally arranged on the basis of an original valve part according to the actual need of ships and the site requirement of ship survey of ship owners, the purchasing cost is saved, and the goods supply period is shortened greatly.

Description

technical field [0001] The invention relates to the technical field of valve parts, in particular to a valve locking device. Background technique [0002] On ships, due to reasons related to the safety of ship operations or anti-fouling oil, etc., it is necessary to keep some valves in "normally closed", "normally open" or certain specific states. The locking device is used to lock the operating shaft pin of the valve. The current way is that before the valve parts leave the factory, the locking device is uniformly fixed on the valve parts by the manufacturer. This kind of approach has the following disadvantages: [0003] 1. Since the locking device is uniformly fixed on the valve parts by the manufacturer, it needs to be requested by the manufacturer during the ordering stage. If the ordering requirements for the locking device are omitted or the shipowner only requests to add this function after the pipeline installation is completed, only Replace the entire valve, whi...
