I. Can the location of the floor heating water divider be changed?
The location of the floor heating water divider is wrong and it is difficult to change. Why is it difficult to change the sub-catchment of the floor heating? This should be considered from the characteristics of the installation of the floor heating sub-catchment, the water inlet pipe, the site pipe and so on. Taken together, we will find that it is very difficult to change the floor heating sub-catchment. It is embodied in the following three points.
1. The main pipeline of floor heating needs to be reinstalled. Because the pipeline of the main water inlet pipeline of the floor heating includes the water supply pipeline and the return water pipeline, their pipe diameters are basically dn32 or dn25. The supply and return water have corresponding valves, filters and so on. If we change the position of the sub-catchment, we need to cut off the water supply and return pipes, and then take a longer way to meet the position movement. Therefore, it is actually very difficult to operate.
2. The floor heating pipes need to be re-installed. The heating pipes are all directly connected from the lower port of the water manifold collector. The water supply pipes and return pipes of our floor heating sub-catchment are generally 300mm and 500mm away from the ground, so the parts of these pipes that are exposed to the ground are very short. If we change the position of the manifold, we need to lengthen all these pipes and reconnect them. That is, it is necessary to add joints. In this way, there will be a hidden danger of water leakage, and it is a very large hidden danger, which is generally not allowed.
3. If we change the location of the floor heating sub-catchment, the floor heating heating pipe needs to be lengthened, and then installed on our wall. Because there are so many heating pipes for floor heating, for example, there are 12 return water for ordinary 6-way floor heating. So if it is exposed, it is very difficult and very ugly.
Summary of opinions: If we change the location of the sub-catchment for floor heating, I think there are mainly the following problems: First, the change is relatively difficult, second, the installation effect is very poor, and third, there are serious problems. Leakage hazard. Therefore, for the sub-catchment, once it is positioned, it is very unreasonable to change it.
2. What should I do if the floor heating water divider leaks?
1. Improve the structural design of the water divider
Due to the different structures of various sub-catchments on the market, there are also great differences in installation and use. Taking the most common copper sub-catchment as an example, the assembled sub-catchment is favored by many manufacturers due to its simple production process and low equipment technical requirements. This kind of sub-catchment can be produced with any processing capacity, so this kind of sub-catchment occupies the highest proportion in the market. Of course, there are also many sub-water collectors with strict production process control and reliable quality. Many well-known foreign brands have also continued to use this structure. This type of sub-catchment has many joints, and it is easy to leak water once the process control is not strict; the other type is the integral forged or cast sub-catchment, which greatly reduces the number of assembly nodes and effectively reduces many possible occurrences. The hidden danger point of water leakage is the ideal structure of the existing sub-water collectors available on the market.
2. Improve the connection between the sub-catch and the system
The connection between the sub-catch and the system is also one of the biggest worries of water leakage, usually O-rings or sealing gaskets are often used for the connection between the sub-catchment and the pipe. Because the use environment of the sub-catchment is often impacted by cold and hot water, the general sealing material is easily damaged by aging. Some high-end foreign brands use hard-sealed connections between metals, and many domestic products follow suit. However, because the level of production technology does not meet the requirements, the product accuracy does not meet the requirements of hard-sealing, and the material selection pursues low prices. , the butt-jointed materials do not have the corresponding complementary compressibility, and it is often difficult to achieve a hard seal. Poorly done hard seals tend to be more leaky than O-ring or gasket joints. In order to cater to the market, domestic manufacturers superficially add an O-ring or sealing gasket to overcome the anxiety of users, so that under the repeated and frequent impact of cold and hot water, the floor heating water separator must be carried out in 2-3 years. A replacement or repair is difficult to achieve once and for all like a hard seal. Therefore, it is wise to choose a hard seal to truly solve the hidden danger of water leakage at the joint.
3. Select the appropriate sealing material
In terms of the current production technology level of civilian products, many nodes on the sub-catchment must have O The O-ring is used to complete the sealing, so the material selection of the O-ring is very important. On the sub-collection pipe, at the joint with the floor heating pipe, due to the high impact of cold and hot water, especially the water inlet, the temperature is often high, so a high-temperature resistant material with moderate hardness should be selected, generally EPDM is more suitable; The interface with the valve is sealed, because it is a one-time metal-to-metal sealing connection, and its high temperature resistance performance needs to be considered in the selection of materials. Generally, silicone rubber is better, and its heat resistance and anti-aging properties are better than ordinary ones. EPDM. Experiments show that NBR materials, especially carboxyl NBR and hydrogenated NBR, have excellent high temperature resistance and wear resistance, and are very suitable for the use of sub-catchment temperature-controlled valve stem conditions. EPDM is mostly used, because its performance can basically meet the general use requirements, and the cost is easy to accept.
4. Control of the manufacturing process
In addition to the reasons of structure and material, the control of the manufacturing process is also a necessary link to solve the leakage of the floor heating water separator. If the machining accuracy is not high, the assembled product is loose, and the surface finish of the push valve stem does not meet the requirements, etc., it will also seriously affect the service life of the sub-catchment, and even directly lead to water leakage in the sub-catchment.
To solve the problem of water leakage of the floor heating water separator, it is necessary to continuously improve the quality and quality, so when you install the floor heating water separator, you must choose a trustworthy big brand to buy.
