In the installation of pipeline systems, a special roleplays the method of connection. Obviously, the master is obliged to ensure the maximum tightness of the circuits, be it a sewage system or a standard water pipe. At the same time, there are many ways of reducing the two endings of different pipes. Perhaps, the most technological methods include rations. But it is not always possible. As an alternative, it makes sense to use the bell. This is a special extension at the end of the pipe, through which a fairly dense and tight joint is also realized.
Externally the design of the pipe end with a bellresembles a funnel. In essence, this is a kind of tip in the form of a segment with extensions. The other end of the pipe is inserted into it, and then the fixation is made. That is, the bell is an element, thanks to which the structural support of the connection is provided. Another thing is that the quality of this node will be influenced by the main way of fastening two different endings.
In this case, the socket can not be regarded only asfunnel, which is attached to this or that pipe. In the device of modern tips of this type are provided and metal stop components, and sealing rings. The task of auxiliary fittings, which is complemented by a pipe with a bell, is to prevent the physical divergence of the main structure with the funnel, as well as to increase the tightness of the connecting unit.
Монтаж раструба можно выполнять только на correctly prepared basis. This should be a pipe with an edge on which the chamfer is of the order of 15 degrees. Usually the bell itself is made of a polymer material, and the target structure can also be represented by metal. When choosing the sizes, it is important to consider that the inside diameter of the socket should correspond to the thickness of the pipe by the external indicator.
Next, a fixation is performed usingsealing materials. At the same time, the socket of the sewer pipe can be equipped with two o-rings at the base connection. This will greatly improve the reliability of the circuit. All operations at this stage are desirable to be performed with strict calculation for further connection with another pipe. Therefore, for example, in advance it is necessary to calculate the parameters of the entire structure along the length.
Classification is based on materialmanufacture of the main pipe. Sockets can be used for rigging cast iron, steel, reinforced concrete and ceramic models. Each material assumes its own approach to providing reinforcement, individual nuances of further connection with another ending.
For example, a cast iron socket can be used inpipelines for various purposes, including when equipping the sewer infrastructure. But the main difference between these pipes, in terms of the use of the bell, is the approaches to installation. So, the main coupling is made with the help of sealing material, but without the use of lubricating components. But in other cases, use a variety of methods of connection, which should be considered in more detail.
In the installation specialists recommend usingglued joint, stop components, as well as welding. In this case, the socket joint itself provides basic support for the clutch. The simplest solution is the use of sealing stoppers. Proper installation will ensure the attachment and stiffness, and tightness. This option is usually used if you want to implement a domestic pipeline. In this case, the sewer funnel, supplemented with seals, will cost inexpensively and at the same time will ensure optimum efficiency.
Adhesive bonding can be performedaccessory function of adhesive bond. It significantly increases the reliability of the design, but it can not be applied with every material. As for soldering, it has its own limitations in terms of use. In this case, the pipe material and the conditions that exclude the possibility of working with such equipment can become a barrier to welding.
To the merits of the trumpet is the provision ofreliable mechanical protection. With this equipment, the seam can be protected from damage by third-party fittings, as well as from climatic influences. Actually, it could be used in each case of connection implementation, but there are certain limitations. In particular, the presence of the socket will not allow the user to perform a truly high-quality sealing with special compounds. This is the main disadvantage of this device. It is important not to forget that the bell is a kind of nozzle, which, in essence, hides the junction point, and also excludes access to it.
Монтаж через раструб является оптимальным variant of the connection. It is used both in the maintenance of industrial pipelines, and in domestic repair operations. However, when addressing this method of joint implementation, it is important not to forget that such a scheme will provide additional compaction of the structure, which is not always appropriate. But, if the installation was carried out correctly and without disturbing the sealing information technology, you can count on the long-term use of the circuit.
In terms of reliability and endurance, the bell isA suitable option not only for private drainage networks. It is also used in the maintenance of sanitary equipment for public and industrial premises. Another thing is that in such cases, valves with technical and operational qualities of a different, higher level are used. For example, the quality of the connection will depend on the origin of the material from which the bell is made. It has already been noted that it is more often produced from polymers. But there are also special modifications of plastics, designed for durable operation in harsh conditions.
