AI Technical Summary
The existing secondary heating grid valves are mostly made of cast iron or steel, which are easily corroded by groundwater, especially in coastal areas, which lead to damage and high maintenance costs. They are prone to leakage during heating in winter, affecting the heating effect.
The PERT II corrosion-resistant heating secondary mesh valve group is adopted, including flange regulating valve and flange soft connection. The material of the flange regulating valve is engineered plastic, which is suitable for temperature range between minus 14 degrees Celsius and 140 degrees Celsius, and the length of flange soft connection is between ten centimeters and twenty centimeters.
By using corrosion-resistant engineering plastic materials and appropriate flange connection design, the service life is significantly improved, the maintenance costs are reduced, the winter leakage problem is avoided, and the stability and safety of the heating system is ensured.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heating, in particular to a PERT II type corrosion-resistant heating secondary network valve group. Background Art
[0002] Heating is the earliest building environment control technology developed by mankind. Since humans learned to use fire, in order to resist the threat of cold to survival, they invented heating methods such as kangs, stoves, fire walls, and fire floors. These are the earliest heating equipment and systems, some of which are still in use today. Today, heating equipment and systems have made great progress in human comfort and hygiene, the beauty and dexterity of equipment, automatic control of systems and equipment, diversification of system forms, and effective use of energy. However, most of the valves in the secondary heating network are made of cast iron or steel. They are affected by groundwater, especially in coastal areas. The chlorine content of groundwater is high and it is easy to corrode and age. The well chamber settlement valve is easily damaged, the maintenance cost is high in summer, and leakage in winter has an adverse effect on heating. Utility Model Content
[0003] The utility model aims to provide a PERT II type corrosion-resistant heating secondary network valve group, which has the advantage of corrosion resistance.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PERT II corrosion-resistant heating secondary network valve group, including a flange regulating valve, both sides of which are fixedly connected with flange flexible connections, and the front surface of the flange flexible connection is provided with a reinforced flange.
[0005] As a preferred solution, the material of the flange regulating valve is engineering plastic, and the flange regulating valve can adapt to a temperature between minus fourteen degrees Celsius and one hundred and forty degrees Celsius.
[0006] As a preferred solution, the length of the flange flexible connection is between ten centimeters and twenty centimeters.
[0007] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0008] The utility model solves the problem that most of the current secondary heating network valves are made of cast iron or steel, which are affected by groundwater, especially in coastal areas. The chlorine content of groundwater is high and is easily corroded and aged. The well chamber settlement valves are easily damaged, the maintenance cost is high in summer, and leakage in winter causes adverse effects on heating. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0012] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0013] Embodiment 1:
[0014] See also Figure 1 As shown, the utility model provides a PERT II type corrosion-resistant heating secondary network valve group, including a flange regulating valve 3, both sides of the flange regulating valve 3 are fixedly connected with flange flexible connections 2, and the front surface of the flange flexible connection 2 is provided with a reinforced flange 1.
[0015] Through the above technical scheme, the present technical scheme solves the problem that most of the valves in the secondary heating network are currently made of cast iron or steel, which are affected by groundwater, especially in coastal areas. The groundwater has a high chlorine content and is very prone to corrosion and aging. The well chamber settlement valves are easily damaged, the maintenance cost is high in summer, and leakage in winter causes adverse effects on heating.
[0016] Embodiment 2:
[0017] On the basis of embodiment 1, the present invention is as follows Figure 1 As shown, the material of the flange regulating valve 3 is engineering plastic, the temperature that the flange regulating valve 3 can adapt to is between minus fourteen degrees Celsius and one hundred and forty degrees Celsius, and the length of the flange flexible connection 2 is between ten centimeters and twenty centimeters.
[0018] The working principle of the utility model is: by replacing the original steel material with PERT II type plastic material, the service life can be greatly improved to more than 30 years. It has the advantages of corrosion resistance, anti-aging, good insulation effect, easy maintenance, repair and maintenance, and simple operation. It is standardized in production and flange connection, and can be quickly replaced during winter heating. The compensation design on both sides solves the damage caused by well chamber settlement, and solves the problem that most of the current heating secondary network valves are made of cast iron or steel, which are affected by groundwater, especially in coastal areas. The chlorine content of groundwater is high and it is very easy to corrode and age. The well chamber settlement valve is easily damaged, the maintenance cost is high in summer, and leakage in winter heating causes adverse effects on heating.
[0019] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and ratio of various elements, and parameter values (e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present utility model.
