Description

Technical Field

[0001] The utility model relates to the technical field of gas pipelines, in particular to a concealed gas casing assembly. Background Art

[0002] At present, for the renovation or repair of old gas pipelines, the method generally adopted by the industry is to completely dismantle the entire aging or damaged gas pipe. During the disassembly process, the staff needs to be extra careful to ensure that no damage is caused to other parts of the pipeline or facilities. At the same time, the safety of the operation must be guaranteed to prevent dangerous situations such as gas leaks. After the disassembly is completed, the next work is to install a brand new gas pipe. Although this method is relatively cumbersome, its effect is significant. It can fundamentally solve the problems of old pipelines and ensure people's daily life needs. However, there is a problem with this approach. When only a small section of the gas pipeline is damaged, if the entire pipeline is still replaced, it will undoubtedly cause a huge waste of resources.

[0003] The inventor has previously developed a concealed gas casing assembly that repairs the gas pipeline by first cutting off the damaged section of the gas pipe and then connecting the casing to the cut gas pipe network, or by directly sleeve the casing on the damaged position of the gas pipe without cutting off the damaged section. The casing is centered by means of a centering bracket, and the centering bracket needs to be fixedly connected with threaded fasteners during installation so that it is installed on the casing. The installation is cumbersome and the installation efficiency is low.

[0004] The utility model is made based on the above situation. Utility Model Content

[0005] The utility model overcomes the shortcomings of the prior art and provides a concealed gas casing assembly with low gas pipeline repair cost and high installation efficiency.

[0006] The utility model is realized by the following technical solutions:

[0007] A concealed gas casing assembly comprises an outer cover and a casing arranged in the outer cover and capable of being sleeved on a gas pipe. The outer cover is formed by splicing a first cylinder shell and a second cylinder shell. A first connecting structure for connecting the first cylinder shell and the second cylinder shell is provided at the splicing point thereof. At least two pads for supporting the casing so that the casing is located in the middle of the outer cover are provided between the casing and the outer cover.

[0008] In the concealed gas casing assembly as described above, the cushion block includes a first cushion block and a second cushion block, the first cushion block is arranged at the lower left of the casing, and the second cushion block is arranged at the lower right of the casing.

[0009] In the above-mentioned concealed gas casing assembly, the first cushion block and the second cushion block are both semi-cylinders.

[0010] In the concealed gas casing assembly as described above, the first cylinder shell and the second cylinder shell are arranged in an upper and lower distribution, the first cylinder shell is located above the second cylinder shell, the arcuate surfaces of the first cushion block and the second cushion block abut against the inner wall of the second cylinder shell, the first cushion block and the second cushion block are both provided with a supporting plane for supporting the casing, and the axes of the first cushion block and the second cushion block are both located on their respective supporting planes.

[0011] In a concealed gas casing assembly as described above, the first gasket and the second gasket have the same structure and size, the first cylinder shell and the second cylinder shell are both fan-shaped with a central angle of 180°, the radius of the inner wall of the second cylinder shell is R1, the radius of the outer wall of the casing is R2, the cross-sectional radius of the first gasket and the second gasket is R3, and R2+R3=R1.

[0012] In the concealed gas casing assembly as described above, the first connection structure includes a first connection plate arranged at the joint of the first cylinder shell and a second connection plate arranged at the joint of the second cylinder shell, a first mounting hole is arranged on the first connection plate, and a second mounting hole is arranged on the second connection plate at a position corresponding to the first mounting hole.

[0013] In the concealed gas casing assembly as described above, an O-ring for sealing is provided between the first connecting plate and the second connecting plate.

[0014] In the above-mentioned concealed gas casing assembly, the first connecting plate is provided with a first groove for placing the O-ring, and the second connecting plate is provided with a second groove for placing the O-ring at a position corresponding to the first groove.

[0015] In the concealed gas casing assembly as described above, the sum of the groove depth of the first groove and the groove depth of the second groove is smaller than the diameter of the cross section of the O-ring.

[0016] In the concealed gas casing assembly as described above, the O-ring is adhered to the inner wall of the first groove or the second groove by adhesive.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] 1. When the gas pipe is found to be damaged, the damaged section of the gas pipe can be cut off first, and then the casing can be connected to the cut gas pipe network. Alternatively, the damaged section can be left uncut and the casing can be directly placed on the damaged position of the gas pipe to complete the repair of the gas pipeline, thereby reducing the cost of maintenance. At the same time, an outer cover is installed on the casing to protect it. There are at least two pads between the casing and the outer cover to support the casing so that the casing is located in the middle of the outer cover, so that the casing is centered. The central installation of the casing can improve the safety of the casing, protect the pipeline, and facilitate subsequent maintenance and inspection work. This can ensure the normal operation and safe use of the gas system. At the same time, the pad only needs to be placed in the outer cover, and no other connection structure is required for connection. The installation efficiency is high, reducing the time cost of construction personnel.

[0019] 2. The arcuate surfaces of the first cushion block and the second cushion block abut against the inner wall of the second cylindrical shell. The first cushion block and the second cushion block are both provided with a supporting plane for supporting the sleeve.

The radius of the inner wall of the second cylindrical shell is R1, the radius of the outer wall of the sleeve is R2, the cross-sectional radius of the first cushion block and the second cushion block is R3, R2+R3=R1. When the sleeve is pressed downward or the second cylindrical shell is lifted upward, the arcuate surfaces of the first cushion block and the second cushion block can rotate along the inner wall of the second cylindrical shell to fine-tune the position of the sleeve, so that the outer wall of the sleeve abuts against the central axis of the first cushion block and the second cushion block to achieve a balanced state, so that the sleeve is located in the middle of the outer cover.

[0020] 3. An O-ring for sealing is provided between the first connecting plate and the second connecting plate, and the outer cover can be sealed by the O-ring.

[0021] 4. The O-ring is adhered to the inner wall of the first groove or the second groove by adhesive, so that the outer cover is more convenient to install. BRIEF DESCRIPTION OF THE DRAWINGS
