Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a fire protection pipeline thread connection structure. Background Art

[0002] With the rapid development of engineering construction in recent years, the quality control and construction progress control of the construction site are particularly important, especially because of the fire pipe installation process. The traditional fire pipe installation project uses a clamping connection, but during use, due to the construction workers' operating level problems, the clamp often leaks.

[0003] Most of the existing fire protection pipes use compression-type connection pipes, but the use of compression-type connection pipes requires professional skills training for operators, and if the construction workers cannot accurately control the depth of the compression groove pressed on the pipe surface and the position of the sealing ring placed at the pipe joint, it is easy to cause water leakage at the pipe connection, thereby increasing the technical requirements for construction workers. Utility Model Content

[0004] The utility model aims to provide a fire protection pipe thread connection structure to solve the problem in the background technology that the use of compression-type pipe connection requires construction workers to have high technical skills.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A fire-fighting pipe threaded connection structure comprises a pipe, wherein the inner wall of one end of the pipe is provided with an internal thread, the outer circumferential surface of the other end of the pipe is provided with an external thread corresponding to the internal thread, blocking strips are fixedly installed on the upper and lower sides of the pipe, and one end of the pipe with the external thread is sleeved with a corresponding sealing gasket.

[0007] Preferably, a fixing sleeve is slidably connected to the surface of the pipe, and guide grooves corresponding to the blocking strips are formed on inner walls on both sides of the fixing sleeve.

[0008] Preferably, a bolt is threadedly connected to the surface of the fixing sleeve, and one end of the bolt abuts against the surface of the pipe.

[0009] Preferably, when the pipes are threaded together in sequence, two sides of the sealing gasket respectively abut against one end of the pipe and the surface is deformed.

[0010] Preferably, a sealing layer is provided on the surface of the external thread.

[0011] Preferably, the surface of the external thread that is exposed when the pipeline connection is completed is sprayed with an anti-rust coating.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model respectively opens internal threads and external threads at both ends of the pipeline, and the pipelines can be threaded together in sequence, which is convenient for workers to operate and reduces the difficulty of construction. In addition, the internal threads can be opened in advance during factory processing, and on-site construction workers only need to measure the size and set the external threads, thereby ensuring construction efficiency. In addition, blocking strips are provided on the surface of the pipeline. When the pipeline is placed on the ground, if the construction workers accidentally step on the pipeline, the blocking strips abut against the ground to prevent the pipeline from slipping during rotation, thereby avoiding the construction workers from falling.

[0014] 2. The utility model provides a sealing gasket. When the pipeline is installed, the quality inspector can understand whether the pipeline is tightly connected by observing the deformation of the sealing gasket. This is very convenient and quick, and can effectively avoid water leakage at the pipeline connection, thereby reducing the technical requirements for construction personnel.

[0019] 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.

[0020] See also Figure 1-3The embodiment provides a fire protection pipe threaded connection structure, including a pipe 100, wherein an inner thread 103 is provided on the inner wall of one end of the pipe 100, and an outer thread 101 corresponding to the inner thread 103 is provided on the outer circumferential surface of the other end of the pipe 100, and blocking strips 102 are fixedly installed on the upper and lower sides of the pipe 100, and a corresponding sealing gasket is sleeved on one end of the pipe 100 with the outer thread 101. By respectively providing the inner thread 103 and the outer thread 101 at both ends of the pipe 100, the pipes 100 can be threadedly connected together in sequence, which is convenient for the staff to operate and reduces the construction difficulty. In addition, during factory processing, the inner thread 103 can be opened in advance, and the on-site construction personnel only need to measure the size and sleeve the outer thread 101, thereby ensuring the construction efficiency. In addition, a blocking strip 102 is provided on the surface of the pipe 100. When the pipe 100 is placed on the ground, the construction personnel accidentally step on the pipe 100, and the blocking strip 102 abuts against the ground to prevent the pipe 100 from slipping when rotating, thereby avoiding the construction personnel from falling.

[0021] Furthermore, the surface of the pipe 100 is slidably connected with a fixing sleeve 104, and the inner walls on both sides of the fixing sleeve 104 are provided with guide grooves corresponding to the blocking strip 102. Through the setting of the fixing sleeve 104, when the connection of the pipe 100 is completed, the fixing sleeve 104 is slid along the blocking strip 102 to the connection, and the fixing sleeve 104 is sleeved on the connection to protect and support the connection. When the connection is impacted by external force, the impact force is dispersed to the pipe 100 to avoid direct action on the external thread 101, thereby avoiding disconnection from the weak part of the thread gap of the external thread 101, thereby improving the explosion resistance of the connection.

[0022] Furthermore, a bolt 105 is threadedly connected to the surface of the fixing sleeve 104, and one end of the bolt 105 abuts against the surface of the pipe 100 to fix the fixing sleeve 104 to prevent the fixing sleeve 104 from sliding on one side due to external force.

[0023] It is worth mentioning that when the pipes 100 are threaded together in sequence, the two sides of the sealing gasket respectively abut one end of the pipe 100 and the surface is deformed, wherein the sealing gasket is made of rubber. Through the setting of the sealing gasket, when the pipe 100 is installed, the quality inspector can understand whether the pipe 100 is tightly connected by observing the deformation of the sealing gasket.

[0024] Preferably, a sealing layer is provided on the surface of the external thread 101, wherein the sealing layer is formed by applying one or more of an anaerobic adhesive and polytetrachloroethylene raw tape together. By providing the anaerobic layer, the sealing degree of the connection of the pipe 100 is improved, so that it can withstand higher water pressure.

[0025] Furthermore, when the pipe 100 is connected, the surface of the exposed external thread 101 is sprayed with an anti-rust coating, wherein the anti-rust coating is one or more of iron red phenolic anti-rust paint, zinc yellow anti-rust paint, transparent three-proof paint, gray anti-rust paint, etc. By setting the anti-rust coating, when the pipe 100 is in a humid state, the surface of the exposed external thread 101 is protected to prevent rust.

[0026] Staff;

[0027] First, place the pipe 100 on the bracket and clean the surfaces of the internal thread 103 and the external thread 101. Then, apply anaerobic adhesive or wrap polytetrachloroethylene raw tape on the surface of the external thread 101 as needed. At this time, connect the external thread 101 of the pipe 100 to the inner cavity of the internal thread 103 of the previous pipe 100, so that the two ends of the sealing gasket respectively abut one end of the pipe 100, and the surface of the sealing gasket is deformed. Grasp the fixing sleeve 104 and slide it toward the connection of the pipe 100, and fix the fixing sleeve 104 with bolts 105, and then fix the pipe 100 with a U-shaped clip.
