Problems solved by technology
[0002] In natural water bodies such as rivers and lakes or in industrial and domestic wastewater, water pollution is caused by various reasons. As a strong oxidant without secondary pollution, ozone has been widely used. 1. During the purification and production process of disinfection water, the ozone gas directly contacts the liquid, and is affected by factors such as pressure, drop, siphon, capillary, etc., causing the liquid to flow back into the ozone generator through the pipeline, which will cause irreversible damage to the ozone generator. damage to

Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. Wherein the same components are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "bottom" and "top "Face", "inner" and "outer" refer to directions toward or away from, respectively, the geometric center of a particular component.
[0019] refer to Figure 1 to Figure 2 As shown, an automatic check drain valve in this embodiment includes a valve body 1, the valve body 1 includes an upper body and a lower body, the upper body and the lower body are welded, and deformation grooves are provided at the welding points of the upper body and the lower body, and the deformation The groove is used to eliminate the deformation caused by welding during the welding process of the upper body ...

Abstract
The invention relates to the technical field of drain valves, and discloses an automatic check drain valve which is characterized by comprising a valve body, a valve cavity is formed in the valve body, a valve element, a clamp spring and a microporous titanium plate are arranged in the valve cavity, the microporous titanium plate is fixedly connected with the valve element through the clamp spring, and the microporous titanium plate is arranged in the valve body. The resistance of the microporous titanium plate to water is about 800 times larger than that of the microporous titanium plate to ozone gas, so that the water can push the microporous titanium plate to move upwards, the sealing head located on the lower portion is separated from the sealing groove located on the lower portion, water flows out through the drainage hole, it is guaranteed that no water is stored in the lower cavity, and the phenomenon that the water flows out due to the fact that the water exists in the valve body for a long time is thoroughly eradicated. And the water enters the ozone generator due to leakage and the like.
Description
technical field [0001] The invention relates to the technical field of drain valves, in particular to an automatic non-return drain valve. Background technique [0002] In natural water bodies such as rivers and lakes or in industrial and domestic wastewater, water pollution is caused by various reasons. As a strong oxidant without secondary pollution, ozone has been widely used. 1. During the purification and production process of disinfection water, the ozone gas directly contacts the liquid, and is affected by factors such as pressure, drop, siphon, capillary, etc., causing the liquid to flow back into the ozone generator through the pipeline, which will cause irreversible damage to the ozone generator. damage. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an automatic non-return drain valve for preventing liquid from entering the inside of the ozone generator. [0004] In order to ac...
