Description

Technical Field

[0001] The utility model relates to the technical field of steel liner pipes, in particular to a steel liner pipe component with good anti-corrosion effect. Background Art

[0002] Steel-lined pipe fittings are pipe fittings that use the same lining material as the steel-plastic composite pipe and corresponding sizes to match the pipe. The physical and chemical properties of the steel lining itself reduce the effects of the pipeline conveying medium on the external structure, such as impact force and corrosion, so that the pipeline has high strength, high wear resistance, high corrosion resistance and high temperature resistance, which greatly extends the service life of the pipeline and reduces the cost of users.

[0003] At present, the steel lining inside the existing steel-lined pipe fittings is usually fixed and bonded to the pipe, which makes it very inconvenient to separate the pipe and the steel lining when the steel lining is damaged, greatly reducing the efficiency of steel lining maintenance and replacement. In this regard, we propose an anti-corrosion steel-lined pipe fitting to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figure 1-3 The utility model provides a technical solution: a steel-lined pipe fitting with good anti-corrosion effect, comprising:

[0020] A tube body 1, wherein a corrosion-resistant steel lining 3 is arranged in the inner cavity of the tube body 1, two symmetrically arranged insertion holes 4 are provided in the middle part of the surface of the tube body 1, two semicircular locking hoops 5 are provided on the surface of the tube body 1, and plug rods 6 compatible with the insertion holes 4 are fixedly welded on the inner walls of the two semicircular locking hoops 5, and two limiting holes 7 compatible with the insertion rods 6 are provided on the wall where the corrosion-resistant steel lining 3 is in contact with the inner wall of the tube body 1, and first locking seats 8 are fixedly welded at both ends of one of the semicircular locking hoops 5, and second locking seats 9 are fixedly welded at both ends of the other semicircular locking hoop 5, and through grooves 10 are provided on the first locking seat 8 and the second locking seat 9, and snap-on components are provided on the two first locking seats 8.

[0021] The clamping assembly includes a fixed seat 11, which is fixedly welded on the top wall of the first locking seat 8, and two symmetrically arranged sliding rods 12 are fixedly welded on the fixed seat 11. The two sliding rods 12 are slidably connected with sliding plates 13, and the sliding plates 13 are slidably connected in the through grooves 10. A trapezoidal clamping block 14 is fixedly welded on the outer wall of the bottom end of the sliding plate 13. The sliding plate 13 can slide on the two sliding rods 12 to drive the trapezoidal clamping block 14 to move, so that the trapezoidal clamping block 14 is clamped on the second locking seat 9 at the corresponding position, so that the two semicircular locking hoops 5 can be fixedly connected.

[0022] A tension spring 15 is sleeved on the two sliding rods 12, and the two ends of the tension spring 15 are fixedly connected to the fixed seat 11 and the sliding plate 13 respectively. The reverse elastic force of the tension spring 15 acts on the sliding plate 13, so that the sliding plate 13 can remain in contact with the second locking seat 9 in the absence of external force, thereby keeping the trapezoidal block 14 clamped on the second locking seat 9.

[0023] Two symmetrically arranged positioning grooves 16 are provided on the inner wall of the tube body 1, and two symmetrically arranged positioning rods 17 are fixedly welded on the outer wall of the corrosion-resistant steel lining 3. The positioning rods 17 are slidably connected in the positioning grooves 16. The corrosion-resistant steel lining 3 can be conveniently positioned by the cooperation between the arranged positioning rods 17 and the positioning grooves 16, so that the limiting hole 7 can be accurately aligned with the insertion hole 4, which is convenient for the insertion of the insertion rod 6.

[0024] Both ends of the pipe body 1 are fixedly welded with mounting flanges 2, and the mounting flanges 2 can facilitate the splicing of multiple pipe bodies 1 through the provided fastening bolts.

[0025] Working principle: During the use of the utility model, when the corrosion-resistant steel lining 3 needs to be repaired or replaced, the two sliding plates 13 can be pressed toward the tube body 1 at the same time, so that the sliding plate 13 moves toward the tube body 1 on the first locking seat 8, driving the trapezoidal block 14 to move to the bottom of the through slot 10 of the second locking seat 9, and then pulling the upper semicircular locking hoop 5 upward to separate the first locking seat 8 from the second locking seat 9, and the semicircular locking hoop 5 drives the insertion rod 6 to slide in the insertion hole 4 and disengage from the limiting hole 7. When the two insertion rods 6 are completely out of the limiting hole 7, the corrosion-resistant steel lining 3 can be removed by pulling out the corrosion-resistant steel lining 3. When installing the corrosion-resistant steel lining 3, the two positioning rods 17 are now aligned with the two positioning grooves 16 respectively, and the The corrosion-resistant steel lining 3 slides into the inner cavity of the tube body 1 and aligns the end of the corrosion-resistant steel lining 3 with the end of the tube body 1, and then the two semicircular locking hoops 5 are sequentially engaged on the outer wall of the tube body 1, so that the insertion rod 6 is inserted into the limiting hole 7. During the engagement of the two semicircular locking hoops 5, the trapezoidal clamping block 14 can drive the sliding plate 13 to move toward the tube body 1 and stretch the tension spring 15 when it is squeezed by the second locking seat 9. When the trapezoidal clamping block 14 moves to the top side and is aligned with the bottom wall of the second locking seat 9, the stretched tension spring 15 is reset, driving the sliding plate 13 to slide and fit on the second locking seat 9, thereby driving the trapezoidal clamping block 14 to be engaged on the second locking seat 9, so that the two semicircular locking hoops 5 are fixedly connected, completing the installation of the corrosion-resistant steel lining 3.
