Description

Novel nut for petroleum valve rod

Technical Field

The utility model belongs to the technical field of the nut technique and specifically relates to a novel nut for oil valve rod.

Background

The nut is a nut, and is screwed together with a bolt or a screw rod to play a role in fastening, and one element which is necessary for all production and manufacturing machines is divided into carbon steel, stainless steel, non-ferrous metal (such as copper) and other types according to different materials. The working principle of the nut is that the nut and the bolt are self-locked by friction force. But the reliability of such self-locking is reduced in dynamic loads. In some important occasions, some anti-loosening measures can be taken to ensure the locking reliability of the nut. One of the anti-loosening measures is the locking nut.

There are also three types of lock nuts: the first method is that two identical nuts are screwed on the same bolt, and a tightening torque is added between the two nuts, so that the bolt connection is reliable; the second is a special locknut which needs to be used together with a lockwasher; and the third is that a through threaded hole is drilled from the outer circle surface to the inner circle thread surface of the nut and is used for screwing in a small-diameter countersunk head screw, so that a force in a centripetal direction is applied to the thread, and the locking nut is prevented from loosening.

The locking effect of the existing locking nut is poor, and the phenomenon of automatic falling can be generally caused when the equipment vibrates, so that the installation is unstable, and the stable operation of the equipment is not facilitated.
