Novel electric actuating mechanism

Abstract

The invention relates to the technical field of electric valves, in particular to a novel electric actuating mechanism which comprises a mounting mechanism, a driving mechanism fixed to the top end of the mounting mechanism and a locking mechanism fixed to one side of the top of the mounting mechanism. The mounting mechanism comprises a lower mounting base and an upper mounting base located above the lower mounting base, mounting lugs are arranged on the two sides of the outer portion of the lower mounting base, a plurality of vertical rods are vertically arranged on the periphery of the top face of the lower mounting base, the vertical rods all penetrate through the upper mounting base and are sleeved with buffer springs, and the two ends of each buffer spring are fixedly connected with the lower mounting base and the upper mounting base respectively. The lower mounting base and the upper mounting base are elastically connected, the inner side of a telescopic column is provided with a first rubber sleeve in a sleeve mode, the outer side of the telescopic column is sleeved with a first rubber ring, and a connecting part is also made of the elastic material, so that buffer protection can be provided for the driving mechanism, and internal electronic elements are prevented from being damaged due to vibration.

Description

technical field [0001] The invention relates to the technical field of electric valves, in particular to a novel electric actuator. Background technique [0002] Existing electric valves are generally composed of a valve body that controls fluid flow and an electric actuator that controls the opening and closing of the valve body. Since the electric actuator is driven by a motor to lift the valve stem, it has a very high accuracy for the electric actuator. requirements. Nowadays, electric valves are widely used in oil, natural gas, wastewater treatment, ships and other fields. In the process of use, we found that the current electric actuators of valves still have some shortcomings, such as: [0003] 1. In some harsh working environments, the electric valve will vibrate along with the pipeline, and the electric actuator contains a large number of electronic components, which may easily cause damage to the internal electronic components under severe vibration, that is, the e...

Problems solved by technology

[0003] 1. In some harsh working environments, the electric valve will vibrate along with the pipeline, and the electric actuator contains a large number of electronic components, which may easily cause damage to the internal electronic components under severe vibration, that is, the existing electric actuator is shock-resistant poor performance;

[0004] 2. The existing electric actuator lacks a locking mechanism, that is, when the electric actuator is powered off, with the continuous impact of the fluid on the spool, it is easy to change the position of the spool, thereby changing the opening of the valve, resulting in the failure of the valve. decreased accuracy
