Overhead valve control device of water mist abrasive mixing cylinder

Abstract

The invention relates to an overhead valve control device of a water mist abrasive mixing cylinder. The device comprises a water mist abrasive cylinder body, a stainless steel wire, a guide pulley anda pneumatic traction telescopic cylinder; a mushroom head positioning bracket is arranged at the top of the water mist abrasive cylinder body; an intake port and an exhaust port of the pneumatic traction extension cylinder are connected with air valves; a telescopic rod of the pneumatic traction telescopic cylinder is connected with a support; and the stainless steel wire is wound on the guide pulley, one end penetrates through the mushroom head positioning bracket to connect with a mushroom head overhead valve, and the other end is connected with the support. The device is reasonable in structure, uses the air valves for controlling opening and closing of the overhead valve to achieve good tightness, is more convenient to operate, safe and reliable, and greatly improves the working efficiency.

Description

technical field [0001] The invention relates to the technical field of sandblasting machines, in particular to a top valve control device for a water mist abrasive mixing cylinder. Background technique [0002] The water mist abrasive sandblasting machine realizes the stable and adjustable pressure in the water mist abrasive mixing cylinder through the control of different proportions of water mist abrasive, water mist and compressed air pressure difference, ensures the uniform flow of water mist abrasive and forms a fine spray Sand mist produces continuous and stable spray force. As an important part of the sandblasting machine, the water mist abrasive mixing cylinder plays a decisive role in the sandblasting effect of the sandblasting machine. The height of the water mist abrasive mixing cylinder is generally 2m or higher, and the abrasive inlet is on the top of the water mist abrasive mixing cylinder. It is very difficult to add abrasive, and the abrasive mouth needs to ...

AI Technical Summary

Problems solved by technology

The height of the water mist abrasive mixing cylinder is generally 2m or higher, and the abrasive inlet is on the top of the water mist abrasive mixing cylinder. It is very difficult to add abrasive, and the abrasive mouth needs to be opened and closed manually, which is inconvenient to operate and has potential safety hazards.
