AI Technical Summary
When traditional chemical eye washers do not have heat tracing function in winter, there are problems such as unsafe use, uncontrollable temperature, risk of leakage and high maintenance costs. Moreover, eye washers with self-heating heat tracing are expensive and easy to damage.
An anti-freeze eye washer is designed. By adding an anti-freeze circulation line, industrial water circulates and flows in the eye washer. Combining the span line and the anti-freeze switch valve, it ensures that the water is maintained in winter and can be switched to the circulating water or fire water replenishing pipeline to avoid waste.
Effectively prevent pipelines and valves from freezing, ensuring safe use, reducing maintenance costs, and avoiding waste of resources.

Abstract
Description
Technical Field
[0001] The utility model relates to an anti-freezing eyewash, belonging to the field of chemical emergency equipment. Background Art
[0002] At present, the traditional eyewash in the chemical industry does not have a tracing function. In winter, it uses emptying for anti-freezing or electric tracing for anti-freezing. Emptying cannot be used under emergency conditions and is unsafe. Electric tracing is difficult to match, and problems such as uncontrollable tracing temperature and electric leakage occur; the eyewash with self-contained electric tracing is too costly. Emptying cannot be used under emergency conditions and is unsafe. Electric tracing is difficult to match, and problems such as uncontrollable tracing temperature bringing scalding risks and electric leakage and electric shock due to aging of the circuit occur. If the constant flow is turned down, it doesn't work, and if it is turned up, it causes waste; the eyewash with self-contained electric tracing is too costly, not easy to use, easy to break, and has a high maintenance cost. Summary of the Invention
[0003] In order to achieve the above object, the utility model provides the following technical solutions:
[0004] An anti-freezing eyewash includes a water supply pipeline, a shower head, an eyewash, an eyewash switch valve, a shower head switch valve, and a water supply main valve. A water supply main valve is provided on the water supply pipeline. In front of the water supply main valve is connected to an industrial water pipe network, and behind the valve is connected to the shower head. A shower head switch valve is provided between the shower head and the water supply pipeline. An eyewash is connected between the water supply main valve and the shower head switch valve. An eyewash switch valve is provided between the eyewash and the water supply pipeline; it further includes a cross line and an anti-freezing circulation line. One end of the anti-freezing circulation line is connected in front of the shower head switch valve, and the other end is connected to a circulating water make-up pipeline. An anti-freezing switch valve is provided on the anti-freezing circulation line. The cross line is arranged in front of the water supply main valve and behind the anti-freezing switch valve, and a cross line valve is provided on the cross line.
[0005] Preferably, the anti-freezing circulation line is connected to a fire water make-up line.
[0006] Preferably, a flow meter is provided at the connection of the cross line and the anti-freezing circulation line. The flow meter can view the flow of industrial water in the anti-freezing eyewash and can assist in judging whether there is a tendency for pipelines and valves to freeze.
[0007] Preferably, the shower head switch valve and the eyewash switch valve are ball valves.
[0008] An anti-freezing circulation line is added. In winter, the anti-freezing switch valve is opened to make the industrial water flow in the anti-freezing eyewash, so that the anti-freezing eyewash always maintains a flowing water state. When using it, a quick opening can be achieved by controlling with a ball valve. When the anti-freezing eyewash needs to be taken out for maintenance, it can be taken out through the cross line. The industrial water pipe network can be connected to the circulating water make-up or fire water make-up pipeline to circulate and achieve anti-freezing. At the same time, because the circulating water and the fire water tank continuously supplement fresh water, waste can be effectively reduced.
[0009] The beneficial effects of the present utility model are as follows:
[0010] 1. The present utility model can make industrial water flow in the anti-freeze eyewash, effectively preventing pipelines and valves from freezing in winter, and effectively solving the anti-freeze problem of the eyewash.
[0011] 2. After passing through the anti-freeze eyewash, the industrial water enters the circulating water make-up pipeline or the fire water make-up pipeline, without causing waste of industrial water. Description of the Drawings
