Description

Technical Field

[0001] The utility model relates to the field of transformation of adding a drainage valve to a reverse osmosis water production pipe, in particular to a reverse osmosis water production pipe with a drainage valve. Background Art

[0002] Starting from the raw water pool, the raw water pool is lifted by the multi-media water supply pump and then enters the multi-media filter unit, self-cleaning filter, and ultrafiltration unit in turn. The ultrafiltration produced water will enter the ultrafiltration water production tank; the ultrafiltration water production tank enters the primary reverse osmosis system through the primary reverse osmosis water supply pump and the primary reverse osmosis high-pressure pump, and the produced water enters the primary reverse osmosis water production pool, and the primary reverse osmosis concentrated water enters the primary reverse osmosis concentrated water pool. The primary reverse osmosis produced water enters the secondary reverse osmosis system through the secondary reverse osmosis water supply pump and the secondary reverse osmosis high-pressure pump, and the produced water enters the secondary reverse osmosis water production pool, and is sent to the use point by the secondary reverse osmosis external water supply pump.

[0003] The equipment and water pumps are on the third floor of the plant, and the water pool is on the first floor. During normal operation, the water flows into the water pool by gravity. However, when starting and stopping the equipment, there is air in the pipeline, which causes a strong pressure difference, resulting in the water not being able to flow into the pool by gravity, and also causing damage to the rupture membrane of the protective device. At the same time, the water production pipeline is divided into two parts for use, one part is supplied to users, and the other part is used as good water to supplement other systems or as raw water for dosing configuration. The two pipelines have different diameters for different purposes, resulting in the small diameter part being unable to enter the water, affecting its own function.

[0004] Therefore, it is necessary to transform the reverse osmosis water production pipe. Utility Model Content

[0005] The utility model provides a reverse osmosis water production pipe with a drainage valve, which solves the problems of bursting membrane damage caused by pipeline pressure difference in the existing water production pipeline and the reasonable allocation of water uses in two pipelines.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A reverse osmosis water production pipe with a drain valve comprises a reverse osmosis water production pipe, wherein one end of the reverse osmosis water production pipe connected to a device is a water inlet end, and one end of the reverse osmosis water production pipe connected to a water pool is a water production end; an opening is provided on the reverse osmosis water production pipe near the production end, the opening is connected to the drain valve, a small tube is connected to the drain valve, and a plurality of filter screens are provided in the small tube.

[0008] Furthermore, the reverse osmosis water production pipe is also provided with small holes connected to the segmented pipeline.

[0009] Furthermore, the opening is arranged above the reverse osmosis water production pipe relatively above the small hole.

[0010] Furthermore, the number of the filter screens is six.

[0011] Furthermore, the filter net is provided with a plurality of filter holes, and the diameter of the filter holes is 30 to 50 meshes.

[0012] Furthermore, the six filter screens are staggered, and the filter holes of the upper filter screen and the lower filter screen are staggered.

[0013] The beneficial effects of the utility model are:

[0014] The utility model sets a drain valve, so that after the equipment is started and stopped, the reverse osmosis produced water can flow into the reverse osmosis pool by itself, and the bursting membrane outside the reverse osmosis produced water pipe is not damaged; the water in the small pipeline can also play its different uses, saving energy without adding a water pump.

[0020] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation.
