Liquid supply device and operation method thereof

Abstract

The invention discloses a liquid supply device, and further discloses an operation method of the liquid supply device. The liquid supply device comprises a driving rod, a driving device, a driving endsleeve, a liquid pipeline, a supply end sleeve, a cone valve which is positioned in the liquid pipeline, is connected with the driving rod, and extends into the supply end sleeve through an opening of the liquid pipeline, and a supply end sealing element fixed in the supply end sleeve, wherein the driving device drives the driving rod, so that multiple-opening states of the cone valve are switched. The operation method comprises the following steps that the liquid pipeline is filled with a required liquid, and negative pressure is provided or the liquid is drained; the cone valve is opened through the driving device; and the cone valve is closed through reverse driving of the driving device. According to the liquid supply device and the operation method thereof, different supply requirements of different products on liquid demand can be met through the supply device, the device is simplified, supply accuracy is improved, supply response is timely, and supply control is more accurate.

Description

technical field [0001] The present invention relates to the field of liquid supply, and more specifically relates to a liquid supply device and an operation method thereof. Background technique [0002] In the paint shop, the anti-corrosion process of the body cavity needs to inject liquid wax into the cavity of the body floor through a proprietary fixture device. According to the requirements of anti-corrosion function of the cavity of the body, for different models, and even the cavity of the bottom plate with different sizes and structures in the same model, it is necessary to inject different amounts of liquid wax. [0003] Existing wax supply equipment is driven by cylinders. The disadvantage is that the cylinder can only be supplied for a single supply, and the control accuracy cannot be guaranteed; therefore, it can only be used for a single model, and cannot meet the matching of different wax supplies required by multiple models. [0004] On the other hand, the end...

AI Technical Summary

Problems solved by technology

The disadvantage is that the cylinder can only be supplied for a single supply, and the control accuracy cannot be guaranteed; therefore, it can only be used for a single model, and cannot meet the matching of different wax supplies required by multiple models.

[0004] On the other hand, the end of the valve body of the existing wax supply equipment generally has a spring leakage mechanism

However, this spring leaking structure is complex in structure, easy to wear, and is a vulnerable part, which requires frequent replacement of spare parts, high maintenance costs, and repeated filling of the supply end, resulting in delays in liquid supply and inaccurate control of supply volume
