Handle assembly of regulating valve

Abstract

The invention provides a handle assembly of a regulating valve, which comprises a disc-shaped handle seat, a handle body and a locking pin, wherein the disc-shaped handle seat is fixedly connected with the regulating valve, and the handle body and the locking pin are arranged on the handle seat. An appropriate force bearing point can be selected according to the required torque, when the torque is smaller, a user can hold the top end of a holding part of the handle body, and when the larger torque is needed, the user can also hold the side end of the holding part of the handle body. Meanwhile, no matter how the force bearing point is selected, the uniformity of circumferential force bearing can be ensured, the handle body rotates steadily without vibration, and the handle assembly saves the radial size space under the condition of ensuring the torque; under the condition of not changing the structure of the regulating valve, instead of an electric power executing assembly, the handle assembly can directly realize the replacement from the opening of an electric control valve to manual control, the control precision is within 5% of the nominal value, and the handle assembly is especially suitable for manual regulation control of a dynamic balance manual regulating valve.

Description

technical field [0001] The present invention relates to valve fittings, and more particularly to a handle assembly for a regulating valve. Background technique [0002] The adjustment handles of common valves on the market are generally disc-type or long-handle-type. The rotation characteristics of the disc-type handle are not obvious, and it is not easy to lock, and the point of force is on the circumference of the disc, which will affect the force application effect when the circumference encounters obstacles; the long-handle handle is easy to be stressed, but its extension If the size is too long, rotation interference often occurs in narrow spaces such as pipe wells. The outward appearance of above-mentioned two kinds of handles is not prominent enough. There are also handle assemblies that meet both appearance and specific usage requirements on the market, but usually have complex structures, high cost, and generally high requirements for the usage environment, and ar...

Problems solved by technology

The rotation characteristics of the disc-type handle are not obvious, and it is not easy to lock, and the point of force is on the circumference of the disc, which will affect the force application effect when the circumference encounters obstacles; the long-handle handle is easy to be stressed, but its extension The size is too long, and rotation interference often occurs in narrow spaces such as pipeline wells

The appearance of the above two handles is not prominent enough

There are also handle components on the market that meet both appearance and specific use requirements, but usually have complex structures, high cost, and generally high requirements for the use environment, and are suitable for cleaner use environments
