Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipes, in particular to an anti-falling hydraulic casing. Background Art

[0002] The existing municipal pipeline construction and greenhouse pipeline construction process will involve the problem of wastewater or rainwater discharge, especially in greenhouses, where irrigation or heavy rain precipitation needs to be discharged in a timely manner. This is generally solved by increasing the diameter of the pipeline, but it will increase the construction cost, and the pipeline bends are only connected by simple splicing and snap-ons. When faced with large amounts of water, the water will fall off if the water volume increases in a short period of time, resulting in the problem that the water flow cannot be smoothly recovered or enter the designated location, thereby causing waste or pollution of water resources. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the existing drainage pipe turning interface is easy to fall off when facing a sudden increase in drainage.

[0004] In order to solve the above technical problems, the technical solution of the utility model is to provide an anti-falling hydraulic sleeve, including an inner sleeve and an outer sleeve, the inner sleeve includes a first straight pipe, a second straight pipe and an elbow, the first straight pipe and the second straight pipe are respectively connected at both ends of the elbow, the outer sleeve is sleeved on the outside of the inner sleeve, and there is a gap between the two, the two ends of the outer sleeve extend to the outside of the first straight pipe and the second straight pipe respectively, and one end of the outer sleeve is tightly and sealedly connected to the first straight pipe.

[0005] Optionally, the other end of the external sleeve is open, that is, the external sleeve is not connected to the second straight tube.

[0006] Optionally, the other end of the external sleeve is tightly and sealingly connected to the second straight tube.

[0007] In summary, the utility model arranges an external sleeve at the bend of the drainage pipe, so that drainage can still be carried out after the internal elbow falls off, and the use is not affected. One end of the external sleeve can be opened to facilitate observation of the internal situation, and it can be arranged only at the connection point, which is low in cost.

[0013] The following combination Figure 1-4 The utility model is described in further detail.

[0014] The utility model discloses an anti-falling hydraulic sleeve, comprising an inner sleeve and an outer sleeve 2, wherein the inner sleeve comprises a first straight pipe 3, a second straight pipe 5 and an elbow 4, the first straight pipe 3 and the second straight pipe 5 are respectively connected to the two ends of the elbow 4, and are both connected to the elbow 4 in a splicing or snap-fit ​​manner, the outer sleeve 2 is sleeved outside the inner sleeve, and there is a gap between the two, and the two ends of the outer sleeve 2 extend to the outside of the first straight pipe 3 and the second straight pipe 5 respectively.

[0015] Example 1

[0016] Reference Figure 1 and Figure 2 In this embodiment, one end of the external sleeve 2 is tightly and sealedly connected to the first straight pipe 3, and the other end of the external sleeve 2 is open, that is, the external sleeve 2 is not connected to the second straight pipe 5, and the elbow 4 is straight or Z-shaped.

[0017] This embodiment is used in the vertical section or the vertical-to-horizontal section of the drainage pipe. The open end of the external sleeve 2 is arranged in the vertical section, which is convenient for observing the situation inside the external sleeve 2.

[0018] During use, water flows in the second straight pipe 5. When the water flow suddenly increases, the elbow 4 may fall off due to the impact. At this time, the water in the second straight pipe 5 flows into the external sleeve 2. Since the external sleeve 2 is sealed and connected to the first straight pipe 3, the water in the external sleeve 2 will flow into the first straight pipe 3 and continue to be discharged backward along the first straight pipe 3.

[0019] Example 2

[0020] In this embodiment, if Figure 3 and Figure 4 As shown, one end of the external sleeve 2 is tightly and sealedly connected to the first straight pipe 3, and the other end is tightly and sealedly connected to the second straight pipe 5, and the elbow 4 is L-shaped or straight.

[0021] This embodiment is used at the bends of horizontal drainage pipes or at the joints of horizontal pipes. Both ends are sealed and connected to straight pipes. After the elbow 4 falls off, the water flows into the outer sleeve 2 and continues to flow out along the straight pipe without causing leakage.

[0022] In other embodiments, both ends of the external sleeve 2 can be integrally formed with the first straight tube 3 or the second straight tube 5 for better sealing. The shape of the elbow 4 can be U-shaped or Y-shaped, and the external sleeve 2 can be manufactured according to the shape of the elbow 4.

[0023] The utility model is provided with an external sleeve 2, and discharge can still be performed after the elbow 4 falls off, without affecting the use, and can be provided only at a turning point or a connecting point, with low cost and good effect.

[0024] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
