Description

Technical Field

[0001] The embodiments of the utility model relate to the technical field of one-way valves, and in particular to a high-pressure hose with a one-way mechanism. Background Art

[0002] Gas fire extinguishing systems are indeed a very effective way to extinguish fires, especially in places where water or foam fire extinguishing agents cannot be used. They are often used to protect equipment and items that are sensitive to water or foam, such as electronic equipment, documents and archives, artworks, etc.

[0003] Gas fire extinguishing is the preferred firefighting method in some critical locations due to its high efficiency, environmental friendliness, pollution-free operation, residue-free operation, non-conductivity, and rapid fire extinguishing. Commonly used gas extinguishing agents include heptafluoropropane, IG-541 (inert gas), nitrogen, perfluorohexanone, and carbon dioxide. Gas fire extinguishing systems are commonly used in protected areas such as communications rooms, data centers, cultural relics repositories, treasure repositories, power distribution rooms, and switch rooms. Gas extinguishing agents are typically stored in high-pressure cylinders, which are connected to subsequent extinguishing agent delivery pipelines via cylinder valves. These pipelines then continue to the sprinklers within the protected area. When the gas fire extinguishing system is activated, the extinguishing agent is released from the storage cylinder, through the cylinder valve and pipelines, and finally through the sprinklers into the protected area.

[0004] At present, the structure of the gas fire extinguishing system is to set up independent release hoses and one-way valves. When installing, the one-way valve is first installed on the manifold, and then the release hose is connected to the one-way valve. The installation adds a connection link between the release hose and the one-way valve.

[0005] Furthermore, because the pressure of the gaseous fire extinguishing agent is usually high when it is released, often reaching around 50 bar or even higher, the connection between the release hose and the one-way valve requires high sealing performance. This places high demands on the connection structure of the release hose and the one-way valve, requiring high-precision processing quality to achieve the connection between the two.

[0006] Therefore, the use of an independent one-way valve, on the one hand, has high processing and manufacturing costs, and also increases the installation cost. Utility Model Content

[0007] The embodiments of the present invention provide a one-way valve with a one-way mechanism and a high-pressure hose, so as to at least solve the problems of difficult processing technology and high manufacturing cost in the related art.

[0008] According to one embodiment of the present invention, a one-way valve with a one-way mechanism is provided, comprising an upper valve body, the upper valve body having a first fluid cavity; a lower valve body, the lower valve body being mounted on the upper valve body, the lower valve body having a second fluid cavity; and a valve core, the valve core being mounted at the connection between the first fluid cavity and the second fluid cavity, the valve core comprising a diverter cone, the diverter cone having a reverse cone and a forward cone, the reverse cone being mounted in the first fluid cavity, the forward cone being mounted close to the second fluid cavity, and when the diverter cone is in contact with the lower valve body, the second fluid cavity of the lower valve body is closed.

[0009] In an exemplary embodiment, the splitter cone further includes two splitter shafts, which are respectively installed on the reverse cone and the forward cone.

[0010] In an exemplary embodiment, the splitter cone further includes a plurality of guide ribs, and the plurality of guide ribs are equidistantly installed on the reverse cone.

[0011] In an exemplary embodiment, the guide rib has a connecting portion and a guiding portion, the cross-sectional area of ​​the guiding portion is larger than the cross-sectional area of ​​the connecting portion, and the cross-section of the guide rib is T-shaped.

[0012] In an exemplary embodiment, the diameter of the splitter axis of the reverse cone is larger than the diameter of the splitter axis of the forward cone.

[0013] In an exemplary embodiment, the cross-sections of the forward cone and the reverse cone are quadrilaterals.

[0014] In an exemplary embodiment, a wire clamp spring is further included, and the wire clamp spring is installed between the upper valve body and the lower valve body.

[0015] In an exemplary embodiment, the upper valve body is provided with a thread, and a side of the lower valve body away from the upper valve body is provided with a thread.

[0016] In an exemplary embodiment, the inclination angle of the reverse cone is greater than the inclination angle of the forward cone.

[0017] According to another embodiment of the present invention, a high-pressure hose is provided, comprising a hose, a connector, and a one-way valve with a one-way mechanism as described above, wherein the connector is installed with the one-way valve, and the hose is installed at one end of the connector away from the one-way valve.

[0018] In summary, the diverter cone of the present invention is configured as a two-sided conical structure, which ensures that no matter whether the flow is forward or reverse, the airflow can generate a driving force on the valve core, so that the valve core can move freely; at the same time, the joint surface of the conical surface enables the valve core to be automatically centered, and even if there is a certain gap between the guide rib and the upper valve body cavity wall, it can still fit along the conical surface;

[0019] In the present invention, the guide ribs are evenly distributed around the circumference to ensure uniform force. At the same time, the guide rib interface is designed as a T-shaped structure. On the one hand, the contact area between the guide rib and the inner cavity is increased, making the guidance more stable. On the other hand, the bottom is thinned, and the blocking area on the flow cross section is reduced, which will not affect the flow of forward gas and ensure that the valve core can move stably along the prescribed channel in the valve body cavity of the one-way valve.

[0020] In the utility model, a wire spring structure is adopted to realize the connection between the lower valve body and the upper valve body of the one-way valve, so that the upper valve body can rotate freely around the lower valve body. A connecting thread is arranged at the terminal end of the upper valve body, and the thread can be connected to the manifold. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0032] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified with "first," "second," etc., may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0033] In addition, in this application, directional terms such as "up", "down", "left", and "right" may be defined including but not limited to the orientation relative to the schematic placement of the components in the drawings. It should be understood that these directional terms may be relative concepts. They are used for relative descriptions and clarifications, and they may change accordingly according to changes in the orientation of the components in the drawings.

[0034] In this application, unless otherwise specified or limited, the term "connection" should be understood broadly. For example, "connection" can mean fixed connection, detachable connection, or integration; it can mean direct connection or indirect connection through an intermediate medium. In addition, the term "coupling" can refer to the manner in which electrical connection is achieved for signal transmission.

[0035] As used herein, "about," "substantially," or "approximately" includes the stated value and an average value that is within an acceptable range of deviation from the particular value as determined by one of ordinary skill in the art taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system).

[0036] Reference Figures 1 to 7In this embodiment, a one-way valve with a one-way mechanism is provided. The one-way valve with a one-way mechanism includes an upper valve body 10, a lower valve body 20, and a valve core 30. The upper valve body 10 has a first fluid chamber 101. The lower valve body 20 is rotatably mounted on the first fluid chamber 101 of the upper valve body 10. The lower valve body 20 has a second fluid chamber 201. The first fluid chamber 101 of the upper valve body 10 and the second fluid chamber 20 of the lower valve body 20 are connected. 01 is connected, and the cross-sectional area of ​​the first fluid chamber 101 is greater than the cross-sectional area of ​​the second fluid chamber 201; the valve core 30 is movably installed in the first fluid chamber 101 and the second fluid chamber 201, and the valve core 30 includes a diverter cone 31, which is movably installed between the upper valve body 10 and the lower valve body 20. When the diverter cone 31 is in contact with the lower valve body 20, it closes the second fluid chamber 201 of the lower valve body 20.

[0037] Specifically, the diverter cone 31 includes a reverse cone 311 and a forward cone 312. The reverse cone 311 and the forward cone 312 have opposite inclination directions, and the cross-sectional shapes of the reverse cone 311 and the forward cone 312 are quadrilaterals. In this way, the flow direction of the fluid can be guided to ensure that the fluid can be evenly distributed in the protected area.

[0038] In this embodiment, the inclination angle of the reverse cone 311 is greater than the inclination angle of the forward cone 312. In this arrangement, the diverter cone 31 has a two-sided conical structure of the reverse cone 311 and the forward cone 312, which ensures that the fluid in the upper valve body 10 and the lower valve body 20, regardless of forward or reverse flow, can generate a driving force on the valve core 30, so that the valve core 30 can move freely; at the same time, the joint surface of the reverse cone 311 and the forward cone 312 enables the valve core 30 to be automatically centered and still fit along the conical surface, and helps to form a dynamic balance during the fluid flow process, thereby optimizing the distribution effect of the fluid.

[0039] Furthermore, the diverter cone 31 includes two diverter shafts 32, mounted on the reverse cone 311 and the forward cone 312, respectively, to divert and distribute the fire extinguishing agent. In this embodiment, the diameter of the diverter shaft 32 of the reverse cone 311 is larger than that of the forward cone 312, and the diameter of the diverter shaft 32 of the reverse cone 311 is also larger than that of the forward cone 312. This design may be intended to accommodate varying flow requirements or pressure differences, ensuring smooth passage and effective distribution of the fire extinguishing agent.

[0040] Furthermore, the diverter cone 31 also includes a plurality of guide ribs 33, and the plurality of guide ribs 33 are equidistantly installed on the reverse cone 311 and the diverter axis 32 of the reverse cone 311. That is, the guide ribs 33 and the reverse cone 311 are vertically arranged, and at the same time, the guide ribs 33 are vertically arranged to the diverter axis 32 of the reverse cone 311. In this embodiment, four guide ribs 33 are provided to ensure uniform force.

[0041] It is worth mentioning that the guide rib 33 has a connecting portion 331 and a guiding portion 332 . The cross-sectional area of ​​the guiding portion 332 is larger than the cross-sectional area of ​​the connecting portion 331 . That is, the cross-sectional shape of the guide rib 33 is T-shaped.

[0042] In this way, on the one hand, the contact area between the guide portion 332 of the guide rib 33 and the first fluid cavity 101 is increased, making the guidance more stable. On the other hand, the connecting portion 331 becomes thinner, and the blocking area on the flow cross section is reduced, which will not affect the flow of positive gas, ensuring that the valve core 30 can move stably according to the prescribed channel in the cavity of the upper valve body 10 of the one-way valve.

[0043] Specifically, a wire retaining spring 40 is installed between the upper valve body 10 and the lower valve body 20. With this arrangement, the upper valve body 10 can rotate freely around the lower valve body 20, which can reduce friction and wear, and ensure the sealing and structural stability between the upper valve body 10 and the lower valve body 20, thereby preventing fluid leakage.

[0044] Specifically, a stopper 11 is provided in the first fluid chamber 101 of the upper valve body 10. In this embodiment, the stopper 11 is configured to be annular. The stopper 11 provides a stable flow path and pressure distribution during the fluid flow process, and may also be used to limit the flow direction or speed of the fluid to ensure that the fluid flows along a predetermined path.

[0045] It's worth noting that the upper valve body 10 is provided with threads, located on the side of the stopper 11 away from the diverter cone 31. These threads are used to mount or secure other components, such as the valve core 30 or valve seat, ensuring valve sealing and precise operation. The use of threads also facilitates valve assembly and maintenance. Similarly, the outer wall of the lower valve body 20 is provided with threads for mounting or securing other components.

[0046] Reference Figure 8In another embodiment, a high-pressure hose is provided, comprising any one of the aforementioned one-way valves, a plurality of hoses 50, and a plurality of connectors, wherein the connector is mounted on the one-way valve, and the hose 50 is mounted on the connector, that is, the connector connects the one-way valve and the hose 50 together. In this embodiment, the connector is implemented as a rotatable connector, so that when installing the hose 50, it is not necessary to release the overall rotation of the hose 50.

[0047] Specifically, the one-way valve's lower valve body 20 is directly connected to the hose 50, incorporating an anti-pullout external buckle connector. This allows the hose 50 to be integrated with the one-way mechanism, reducing the number of connections between the one-way valve and the hose 50 and thus reducing system leaks. This also eliminates the need for connection and installation between the one-way valve and the hose 50, further reducing costs.

[0048] In summary, the one-way valve and hose 50 of the above structure provide smooth forward flow and strong flow capacity, reliable reverse flow cutoff, and self-centering of the valve core 30, avoiding the significant pressure loss associated with a spring structure. The valve has a simple structure, reliable operation, and minimal hydraulic friction loss.

[0049] After entering through the upper valve body 10, the fluid first passes through the first fluid chamber 101. Under the thrust of the fluid, the fluid pushes the reverse cone 311 of the diverter cone 31, causing the forward cone 312 to fit against the lower valve body 20. At this time, the second fluid chamber 201 of the lower valve body 20 is closed, and the fluid cannot enter the second fluid chamber 201. At this time, the one-way valve is in a closed state.

[0050] When the fluid enters the second fluid chamber 201 of the lower valve body 20 through the hose 50, the thrust of the fluid pushes the forward cone 312 of the diverter cone 31, causing the diverter cone 31 to move toward the side close to the upper valve body 10. The guide rib 33 of the diverter cone 31 abuts against the stopper 11 of the first fluid chamber 101. At this time, the position of the diverter cone 31 is fixed, and the fluid can enter the first fluid chamber 101 from the second fluid chamber 201, and finally be transported to the designated location along a predetermined route.

[0051] The above content is only a specific embodiment of this application, but the scope of protection of this application is not limited to this. Any changes or replacements within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
