Abstract

The invention provides an explosion-proof pipe device capable of automatically adjusting the flow. The explosion-proof pipe device comprises a frame, an inner pipe is arranged in the frame, a pressurizing and expansion mechanism and a flow controller are arranged on the inner pipe, and the pressurizing and expansion mechanism and the flow controller are connected through a connecting part arrangedon the side wall of the frame; the pressurizing and expansion mechanism provides drive force to the flow controller through the connecting part, and the control of the flow controller to the fluid flow is achieved accordingly; and the connecting part serves as the fulcrum, the pressurizing and expansion mechanism and the flow controller are arranged in the way of lever principle, when the pressure and flow of fluid increase abruptly, the pressurizing and expansion mechanism provides the drive force to the flow controller, and the adjustment of the flow and pressure of the fluid is achieved accordingly through the flow controller, so that the explosion-proof function of the pipe is achieved, and the explosion-proof pipe device is simple in structure and easy to realize.

Description

technical field [0001] The invention belongs to the technical field of engineering building construction, and in particular relates to an explosion-proof pipe device for automatically adjusting the flow rate. Background technique [0002] In engineering construction, such as large-volume concrete water flow, high-pressure spraying operation, grouting operation, etc., various pipeline connections and measurement and control equipment are involved, but there is a lack of corresponding safety control equipment, such as unstable grout pressure and flow control in grouting operations The phenomenon of "pipe burst" is prone to occur, and the grout splashes under high pressure and seriously affects the personal safety of construction workers. The grouting operation cannot be stopped in time, and it is relatively difficult to restore the pipeline. Contents of the invention [0003] The purpose of the present invention is to provide an explosion-proof pipe device that automatically...
