Description

Technical Field

[0001] The invention relates to the technical field of pipelines, and in particular to a pipeline anti-freezing cracking device and a pipeline. Background Art

[0002] In daily life, the safe operation of various domestic water supply pipelines, engineering circulation pipelines, and fire water supply pipelines is of vital importance to people's normal life and safety. The safe operation of various industrial water treatment pipelines is also of extraordinary significance to various industrial productions.

[0003] As we all know, when the ambient temperature drops below zero in winter, various water supply pipes will freeze. The volume of water in the frozen state increases by about 1 / 10, that is, the volume ratio of the same mass of water to ice is about 10:11, which will cause the pipe to rupture. Once ruptured, it will affect the operation of various water supplies. It not only affects people's lives and safety, as well as industrial production, but also leads to a lot of maintenance work, large property losses, and in some cases, maintenance is more difficult. In order to prevent the freezing and cracking of pipes, in various water supply facilities, people often adopt measures such as deep underground pipes, electric heating and pipe insulation, but have never been able to find a reliable solution and technology to properly protect the pipes from freezing and cracking, thereby protecting the pipes from freezing and cracking.

[0004] The present invention is proposed in view of the above. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, an embodiment of the present invention proposes a pipeline anti-freezing cracking device to solve the defect of freezing and cracking of pipelines caused by freezing of water flow in the prior art. By arranging an elastic component on the pipeline, the inside of the pipeline can be deformed when the water flow freezes, thereby avoiding the problem of freezing and cracking of the pipeline caused by freezing of water flow.

[0006] The embodiment of the present invention further provides a pipeline.

[0007] A pipeline anti-freezing cracking device according to an embodiment of the first aspect of the present invention comprises:

[0008] An outer tube body, wherein a flow channel for medium flow is formed inside the outer tube body;

[0009] An inner tube body, disposed in the flow channel;

[0010] A support frame, connected to the inner wall of the outer tube body and the outer wall of the inner tube body respectively;

[0011] Wherein, the inner tube body is provided with an elastic component, and the elastic component can adjust the volume of the flow channel under the action of pressure.

[0012] According to one embodiment of the present invention, the elastic component comprises a silicon capsule disposed inside the inner tube body;

[0013] The silicon capsule comprises an elastic capsule body arranged inside the inner tube body, and a capsule body flange connected to the elastic capsule body and overlapped with the end of the inner tube body.

[0014] Specifically, by arranging an elastic bladder inside the inner tube body, the expansion force of the water flow when it freezes is effectively absorbed. At the same time, the setting of the bladder flange ensures that the elastic bladder can be fixed in relative position with the inner tube body, and the expansion force of the water flow when it freezes is absorbed only by the elasticity of the elastic bladder.

[0015] According to one embodiment of the present invention, the elastic component includes two silicon capsules; wherein the two silicon capsules are arranged at two ends of the inner tube body.

[0016] Specifically, the provision of the two silicon capsules ensures that when the water flow inside the outer tube body freezes, the inner tube body can absorb the expansion force generated by the freezing from two directions.

[0017] According to one embodiment of the present invention, it further comprises: a sealing end cap disposed at the end of the inner tube body;

[0018] The sealing end cap abuts against the end of the inner tube body and squeezes the flange of the bladder body to produce deformation, thereby providing a pre-tightening force for the seal between the elastic bladder body and the inner tube body;

[0019] The sealing end cover is provided with a liquid through hole for letting water into the elastic bladder.

[0020] Specifically, by cooperating with the sealing end cover and the edge of the inner tube end face, the flange of the bladder body is squeezed, thereby achieving sealing between the elastic bladder body and the inner tube body, preventing water from entering through the gap between the elastic bladder body and the inner tube body and then flowing out of the outer tube body to cause water leakage.

[0021] According to one embodiment of the present invention, the elastic component further comprises: a first diaphragm, a second diaphragm and a spring;

[0022] The first baffle is arranged corresponding to the elastic bladder and abuts against the backwater side of the elastic bladder;

[0023] The second partition is fixedly connected to the inner wall of the inner tube body;

[0024] The spring is disposed between the first partition plate and the second partition plate.

[0025] Specifically, by providing the first baffle and the spring, the restoring force of the elastic sac is achieved, so that the elastic sac, which is extended by the expansion force when the water flow freezes, can shrink under the action of the spring. At the same time, the first baffle can slide in the inner tube to ensure the extension of the elastic sac.

[0026] Furthermore, the second partition enables the elastic sacs arranged on both sides of the inner tube body to be affected by the restoring force of the spring, that is, one end of the spring cooperates with the first partition and the other end cooperates with the second partition, and the reaction force on the elastic sac is achieved by compressing the spring.

[0027] It should be noted that the second partition is fixedly connected to the inner wall of the inner tube body.

[0028] It should also be noted that the second partition can be arranged as an annular structure on the inner wall of the inner tube.

[0029] According to one embodiment of the present invention, the elastic component further comprises: a first diaphragm and a spring;

[0030] The first baffle is arranged corresponding to the elastic bladder and abuts against the backwater side of the elastic bladder;

[0031] The spring is arranged between the two first partitions.

[0032] Specifically, by setting up two first baffles and a spring, the restoring force of the elastic sac is achieved, so that the elastic sac, which is extended by the expansion force when the water flow freezes, can shrink under the action of the spring. At the same time, the first baffle can slide in the inner tube to ensure the extension of the elastic sac.

[0033] According to one embodiment of the present invention, an air channel is provided on the support frame;

[0034] The air channel is connected between the outside of the outer tube and the two elastic bladders inside the inner tube;

[0035] Wherein, the air passage is connected with the two elastic bladders through the tube wall of the inner tube and the second partition.

[0036] Specifically, by providing an air channel, when the elastic bladder is squeezed and deformed, the gas in the inner tube can be squeezed to the outside of the outer tube, thereby avoiding the problem of excessive pressure caused by gas remaining in the inner tube and the inability to compress the elastic bladder.

[0037] It should be noted that the air channel of this embodiment is connected to the inner space of the inner tube body through a support frame connecting the outer tube body and the inner tube body, and the connection with the inner space of the inner tube body is achieved through the second partition.

[0038] According to one embodiment of the present invention, an air channel is provided on the support frame;

[0039] The air channel connects the outside of the outer tube body with the two elastic bladders inside the inner tube body;

[0040] Wherein, the air passage is connected with the two elastic bladders through the tube wall of the inner tube body.

[0041] Specifically, by providing an air channel, when the elastic bladder is squeezed and deformed, the gas in the inner tube can be squeezed to the outside of the outer tube, thereby avoiding the problem of excessive pressure caused by gas remaining in the inner tube and the inability to compress the elastic bladder.

[0042] It should be noted that the air channel of this embodiment is connected to the internal space of the inner tube body by a support frame connecting the outer tube body and the inner tube body. At the same time, the connection with the internal space of the inner tube body is achieved by opening an opening on the inner wall of the inner tube body, and the second partition is slidably arranged in the inner tube body.

[0043] According to one embodiment of the present invention, the outer tube body comprises: a water inlet joint and a water outlet joint;

[0044] The water inlet joint is connected to one end of the outer tube body and is arranged in an open shape with a radial cross section gradually expanding from the water inlet direction;

[0045] The water outlet joint is connected to the other end of the outer tube body and is arranged in a closing shape with a radial cross section of the flow basin gradually decreasing from the water outlet direction.

[0046] Specifically, increasing the guiding effect on the water flow entering and flowing out of the outer tube body can achieve faster flow, and at the same time, the water flow at the water inlet end is quickly diverted in the flow channel to avoid concentration at the location of the elastic sac. At the water outlet end, the water flow in other parts of the flow channel is concentrated to the location of the elastic sac and discharged from the outer tube body.

[0047] A pipeline according to an embodiment of the second aspect of the present invention includes: the above-mentioned anti-freezing and cracking device for a pipeline.

[0062] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] In the description of the embodiments of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limitations on the embodiments of the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0064] like Figure 1 and Figure 2 As shown in FIG. 1 , the first and second schematic diagrams of the assembly relationship of the anti-freezing cracking device provided in the embodiment of the present invention are shown. Figure 1 and Figure 2 It can be seen that the present invention arranges an inner tube body 2 inside the outer tube body 1, and arranges components such as a silicon capsule 4, a spring 8, a first baffle 6, and a second baffle 7 inside the inner tube body 2. When the pipeline water system is operating normally, the spring 8 and the silicon capsule 4 effectively offset the normal pressure of the water and have no effect on the operation of the system. When the pipeline water system is frozen, due to the increase in volume, the expansion force compresses the spring 8 and the silicon capsule 4, effectively absorbing the expansion of the volume and preventing the system from being frozen and damaged. After the pipeline water system is frozen and thawed, the expansion force of the ice disappears, and the spring 8 and the silicon capsule 4 return to their original state under the action of their own elastic force. Since in the freezing process, ice always forms first on the outer circle in the pipeline and gradually expands inward, the device sets the telescopic space at the center position, which is reasonable and protects the entire pipeline from bursting due to freezing.

[0065] In general, the present invention is easy to install and can be compatible with various water supply pipes. At the same time, a heat preservation layer is arranged on the water inlet joint 102, the water outlet joint 103 and the outside of the outer pipe body 1, so that the anti-freezing cracking device provided by the present invention can obtain good heat preservation when connected to other pipes.

[0066] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0067] In the embodiments of the present invention, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0069] The anti-freezing cracking device for pipes provided in the embodiment of the present invention realizes that when the water flow freezes, the inside of the pipe can be deformed by arranging an elastic component on the pipe, thereby avoiding the problem of pipe freezing and cracking caused by the freezing of the water flow.

At the same time, the first partition 6 can slide in the inner tube body 2, thereby ensuring the extension of the elastic sac 401.

[0078] Furthermore, the second partition 7 enables the elastic sac 401 arranged on both sides of the inner tube body 2 to be affected by the restoring force of the spring 8, that is, one end of the spring 8 cooperates with the first partition 6, and the other end cooperates with the second partition 7.

[0084] Specifically, by providing the air channel 301, when the elastic bladder 401 is squeezed and deformed, the gas in the inner tube body 2 can be squeezed to the outside of the outer tube body 1, thereby avoiding the problem that the elastic bladder 401 cannot be compressed due to excessive pressure caused by the gas retained in the inner tube body 2.

[0090] In some embodiments, the outer tube body 1 includes: an inlet joint 102 and an outlet joint 103; the inlet joint 102 is connected to one end of the outer tube body 1, and is arranged in an open shape with a radial cross-section of the flow basin gradually expanding from the water inlet direction; the outlet joint 103 is connected to the other end of the outer tube body, and is arranged in a closed shape with a radial cross-section of the flow basin gradually decreasing from the water outlet direction.

[0091] Specifically, increasing the guiding effect on the water flow entering and flowing out of the outer tube body 1 can achieve faster flow, and at the same time, the water flow at the water inlet end is quickly diverted in the flow channel 101 to avoid concentration at the location of the elastic sac 401.
