Novel multi-station valve element automatic cleaning device

Abstract

The invention discloses a novel multi-station valve element automatic cleaning device. The device comprises a flushing water tank, a flushing device, a clamp and a rack; the flushing water tank is arranged below the rack, water in the water tank is pumped into the flushing device through a pump to flush a valve element on the clamp, the flushed water flows back into the water tank through a hole in the rack to be recycled, the clamp is arranged above the rack, the flushing device is arranged above the clamp, three water spraying holes are formed in the spray head and are aligned with three to-be-cleaned holes in the valve element correspondingly, and the clamp adopts a floating clamping mode. Two pressing blocks are installed on one pressing plate, the pressing plate and the pressing blocks are connected through pins, the positioning benchmark of the valve element is machined with a guide rod hole as the benchmark, the water spraying holes are machined with the guide rod hole as the benchmark, it is guaranteed that the water spraying holes are accurately aligned with 24 holes needing to be cleaned, and the device can automatically and efficiently clean the valve element.

Description

technical field [0001] The invention relates to the technical field of valve core cleaning research, in particular to a novel multi-station valve core automatic cleaning device. Background technique [0002] After the fluid control valve is processed, it is necessary to perform high-pressure flushing on the passage hole on the valve to thoroughly clean the chips inside, otherwise the performance of the valve will be affected. Some valve core structures in the prior art are as follows: Figure 9 shown, requires a pair of 2 with one The hole is cleaned with high pressure, the cleaning water pressure is 20, and the rinse time is 15 seconds. When cleaning, the high-pressure water must be directly aimed at the inner surface of the hole to ensure sufficient pressure and cleaning effect. This requires high-pressure water to flush the three holes separately. Because the hole diameter is small and the distance is small, it is difficult to flush. The current method is to position ...

AI Technical Summary

Problems solved by technology

The current method is to position and clamp a single part on the fixture, and then flush the three holes with high-pressure water; or insert three needles with a diameter of 1.5mm into the three holes for flushing, and the actions are all manually operated. The flushing effect is not good, especially at the orifice.
