PVC transparent electrician tubes are often used in construction engineering areas, and now they have occupied the pipes that are commonly used in people's days. The equipment that can be comfortable in high temperature or high tortuosity is satisfied with the wetness or alkali in the construction environment. Larger localities will not corrode, widening the equipment pipelines used in the use of electrical equipment.
1. Reducing the hindrance of resistance: Under the joint procedure of plastic pipes in different links, the pipelines used need to control the height and width stability of the storage, and the phenomenon that the current flowing through the pipe does not exhibit a large melting density is added. The high-temperature, tortuous plastic pipe has a high volume.
2, the robustness of trampling: PVC electrician threading pipe has passed the steel of rubber thickness, and it can withstand the situation that the articles with different gravity will not be broken easily. Therefore, it is necessary to add the robustness of the plastic equipment used in the pipe. Controls the robustness of the pipe joints in the gravity, avoiding the simple attack of the pipeline.
3, to avoid excessive pipe perforation: because the use of pre-buried pipe lines will present a messy situation, so in order to avoid the plastic pipe cracking the wire equipment in the control line pipe, can finally rely on the embedded wire to control the equipment, so It can avoid the occurrence of a simple break in the formation of zigzag lines.
The connection method of PVC transparent wire tube mainly includes three kinds of sealing rubber ring, bonding and flange connection. When the pipe diameter is greater than or equal to 100 mm, the rubber ring interface is generally used; if the pipe diameter is less than 100 mm, the joint is used, and of course, the union is also selected. When the pipeline crosses the sewer or other pipelines, the metal pipe is generally used. In this case, the flange connection is generally used. The connection between the front and rear of the valve and the pipe is also selected by flange connection.
1. When the small-diameter pipe is solvent-bonded, it is required to round the rounded corners to form the groove, and ensure that the fracture is flat and straight, so that the bond is strong and avoids water leakage.
2. For PVC pipes with a diameter of 100 mm or more, a rubber ring interface is used. Before the equipment, the person must be placed to chamfer the pipe socket and check whether the quality of the rubber ring is qualified. The equipment must be cleaned by the socket, rubber ring, etc.
3. Pipe trench excavation of traditional pipeline equipment is only pleading for the pipe to be placed in the pipe trench and to stop the sealing. When the original soil layer is not loosened, it is not necessary to pressurize the cushion.
4. The general PVC pipe branch can be opened with a tee or a vertical water stop. During the construction, a saddle-shaped fitting can be added with a half-closed tee and clamped with a U-shaped bolt, so that the wall is thickened, and then the hole is directly drilled on the upper surface, and then the externally threaded plastic piece is used for the attachment. The test indicates that the test pressure after the construction is completed by this method can reach the specification. Others can also be placed in the direction of the thrust of the water flow in the pipe, such as elbows, tees and pipe end seals, etc. should be set to thrust the pier to withstand the thrust of the water flow.
