Description
Technical Field
The utility model mainly relates to the technical field of grinding and polishing, in particular to injection of abrasive materials or particulate materials, and particularly relates to a pneumatic valve synchronous control device.
Background
The metal surface cleaning technology is an indispensable procedure before the metal is subjected to surface coating, heat treatment, machining and cold rolling. The quality of the metal surface cleaning directly affects the quality of the surface coating and the quality of the mechanical product. The traditional surface cleaning mainly comprises the processes of manual cleaning, mechanical cleaning, chemical cleaning, electronic cleaning, flame cleaning, jet cleaning and the like, wherein the jet cleaning process is adopted in many cases. The jet cleaning comprises high-pressure water jet sand blasting cleaning, and the principle is that high-speed striking is carried out on the surface of an object after high-pressure pure water and abrasive materials are mixed at a descaling spray head, so that the surface of the object is cleaned.
In the prior art, high-pressure water jet sand blasting cleaning equipment comprises a grinding tank, a plurality of sand discharging openings are arranged below the grinding tank, each sand discharging opening corresponds to a pneumatic valve, and grinding materials in the grinding tank flow out from the sand discharging openings, pass through the pneumatic valves and then flow into a descaling spray head along a sand discharging pipe. The pneumatic valve is used for controlling the supply of the abrasive at the descaling spray heads, and each descaling spray head corresponds to one pneumatic valve. In the operation process of the high-pressure water jet sand blasting cleaning equipment, a plurality of descaling spray heads are usually required to clean the surface of an object at the same time, and the abrasive feeding rhythm of each descaling spray head is synchronous, so that the uniformity and stability of cleaning quality can be ensured. In order to meet the requirements, the adopted mode is that an independent electromagnetic valve is arranged at a pneumatic valve corresponding to each descaling spray head, and a controller synchronously gives out a switching signal to control each electromagnetic valve. However, the number of the electromagnetic valves is large, and the electromagnetic valves are easy to break down or damage, so that the abrasive feeding rhythm is disordered, and the cleaning quality is reduced. Moreover, once the supply of the grinding material of the descaling spray head fails, the failure point can be judged only by checking the pneumatic valve and the electromagnetic valve which are correspondingly connected, so that the maintenance workload is large and complicated in the actual use process. Based on this, there is a need for a pneumatic valve synchronous control device that can achieve an overall regulation function with only a single solenoid valve.
