[CN 201710746342.1] Method for Preventing Loosen of Pipe Joint of Hydraulic Pipeline of Pressure Machinery
[CN 201710746342.1] A Method for Preventing Loosening of Pressure Machinery Hydraulic Pipeline Pipe Joint Title: A Method for Preventing Loosening of Pressure Machinery Hydraulic Pipeline Pipe Joint Application Number: CN 201710746342.1 Applicant: Shanghai Kui Shu Automation Technology Co., Ltd. Application Date: 2017-8-26 Patent Type: Invention Application for a Method for Preventing Loosening of Pressure Machinery Hydraulic Pipeline Pipe Joint. When locking the pipe joint body, through the mechanical transmission device connected with the hydraulic oil of the pipeline, the hydraulic oil of the pipeline is used to provide the locking force. At the same time, the pipe joint body can be locked by using the anti-loosening bolt at the same time. When the pressure of the pipeline is released or the pressure is small or changes slowly, the anti-loosening bolt is mainly used to realize the firm locking of the pipe joint body. When the pressure of the pipeline increases or changes too rapidly, the mechanical conduction device in communication with the hydraulic oil of the pipeline responds quickly and provides a locking effect in cooperation with the anti-loosening bolt.
