Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline valves, and specifically, to a portable one-way valve. Background Art
[0002] A one-way valve is a valve through which fluid can only flow in from the inlet, and the medium at the outlet cannot flow back. It is commonly known as a one-way valve. A one-way valve is also called a check valve or a non-return valve, and is used in a hydraulic system to prevent the reverse flow of oil, or in a pneumatic system to prevent the reverse flow of compressed air. There are two types of one-way valves: straight-through type and right-angle type. The straight-through one-way valve is installed on the pipeline by threaded connection. The right-angle one-way valve has three connection forms: threaded connection, plate connection, and flange connection. A hose is a supplementary pipe body used to extend the stroke of the one-way valve.
[0003] One-way valves and hoses are widely used in equipment. During the installation of valves, due to the inconsistent distances between pipelines and valves, or the non-coaxial directions of two pipelines, although forced installation can meet the usage requirements, the torsion or tension generated on the pipeline may cause unexpected accidents to the pipeline. Vibrations in the pipeline and other factors may exacerbate the loosening of the valve, leading to leakage. In some cases, when the actuator performs a specific action, a large flow rate of the inflowing medium and a small flow rate of the outflowing medium are required, and the valve needs to be able to achieve different bidirectional flow rates.

[0023] The following further describes in detail the embodiments of the present utility model with reference to the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.
[0024] Embodiment 1
[0025] Please refer to Figure 1 - Figure 5, the present utility model: a portable one-way valve, comprising an adjustable valve 1 and a hose 2. Nuts 3 are provided at one ends of both the adjustable valve 1 and the hose 2. A connector 4 is slidably connected to the end of the adjustable valve 1 away from the nut 3. There are two connectors 4 in total. The other connector 4 is fixedly connected to the nut 3 close to the hose 2. Bell mouth connectors are provided at the ends of both connectors 4 facing the hose 2. An inner groove adapted to the bell mouth connector is provided on the inner arc of the end of the hose 2. The connector 4 and the hose 2 are meshed and connected through the bell mouth connector. A one-way cylinder 5 is penetrated and fixedly connected to the center position of the inner groove of the adjustable valve 1. A connecting ring 7 is fixedly connected to the end of the one-way cylinder 5 close to the hose 2. A pull rope 8 is fixedly connected to the inner side of the connecting ring 7. A valve ball 9 is fixedly connected to the end of the pull rope 8 away from the hose 2. The valve ball 9 is meshed and connected to the inner groove at the opposite end of the one-way cylinder 5, and the maximum moving distance of the valve ball 9 does not break away from the opening position of the engaging groove of the one-way cylinder 5, ensuring that the valve ball 9 can be used for blocking and resetting of the one-way passage. Four valve holes 6 are penetrated and opened at the position of the adjustable valve 1 close to the outer side of the one-way cylinder 5. A valve rod 10 is penetrated and slidably connected to the arc wall of the adjustable valve 1 opposite to the valve holes 6. An outer cover 11 is sleeved and slidably connected to the outside of the adjustable valve 1. The outer cover 11 is tapered and inclined. A chute 12 is opened on the inner arc wall of the outer cover 11. A slider 13 is slidably connected to the chute 12 in an adapted manner. The slider 13 is fixedly connected to the valve rod 10. By moving the outer cover 11, the slider 13 slides in the chute 12, enabling the valve rod 10 to slide on the arc wall of the adjustable valve 1, thereby closing and opening the valve holes 6, facilitating the switching of the valve to the two-way valve mode and enhancing the flexibility of the valve use.
[0026] A compression sleeve ring 16 is sleeved and connected to the outside of the connection position between the connector 4 and the hose 2. The stability of the connection between the hose 2 and the connector 4 is ensured through the compression sleeve ring 16, preventing the hose 2 from falling off. Among them, a guide ring 17 is embedded and sleeved on the outside of the connector 4 connected to the end of the adjustable valve 1, and a sealing ring is embedded and fixedly connected to the outer arc wall of the connector 4. A sealing ring is embedded in the inner arc of the hole through which the adjustable valve 1 is close to the valve rod 10. The guide ring 17 can perform sliding limit on the sliding connector 4, ensuring the stability of the hose 2 during the adjustment process.
[0027] Embodiment 2
[0028] Refer to Figure 1 - Figure 5 , on the basis of Embodiment 1, a further improvement is made:
[0029] One end of the outer cover 11 close to the hose 2 is rotatably connected with a knob 14. The outer arc wall of one end of the adjustable valve 1 close to the connector 4 is provided with an external thread. The knob 14 is sleeved on the outside of the adjustable valve 1 and is threadedly connected with the external thread. One end of the adjustable valve 1 close to the connector 4 is rotatably connected with a lock nut 15. The lock nut 15 is threadedly connected with the external thread of the adjustable valve 1. Vertical anti-slip patterns are provided on the outside of both the knob 14 and the lock nut 15. By setting the lock nut 15, the connector 4 where the adjustable valve 1 slides can be locked and fixed, thereby facilitating the length of the hose 2 and the adjustable valve 1. When the knob 14 rotates, when the knob 14 drives the outer cover 11 to move towards the hose 2, at this time the valve stem 10 moves outwards from the valve hole 6, and then the valve hole 6 is opened, so that the valve can have a two-way passage, making the valve more flexible to use. On the contrary, when the knob 14 rotates in reverse, the valve stem 10 can block the valve hole 6, making the valve used as a one-way valve.
[0030] The working principle of the present utility model is as follows: When in use, the adjustable valve 1 and the hose 2 are fixed between two pipes through the nut 3. During installation, the hose 2 is adjusted according to the distance and axial direction between the two pipes. By turning and unlocking the lock nut 15, at this time the hose 2 can move inwards at the end position of the adjustable valve 1 through the connector 4, adjusting the distance between the hose 2 and the adjustable valve 1 suitable for connecting the pipeline. Then, by bending the hose 2, the connecting axial direction can be changed. Subsequently, the fluid flowing into the adjustable valve 1 from the hose 2 direction, through the impact force of the fluid, flushes the valve ball 9 outwards from the one-way cylinder 5. At this time, the valve ball 9 is pulled by the pull rope 8 and the connecting ring 7, so that the valve ball 9 is outside the one-way cylinder 5 and will not break away. On the contrary, when the fluid flows from the adjustable valve 1 to the hose 2 direction, at this time the valve ball 9 is snapped into the meshing groove of the one-way cylinder 5 through the fluid impact, and at this time the one-way passage of the adjustable valve 1 is realized. When it is necessary for the adjustable valve 1 to have a two-way passage, turn the knob 14 by hand to drive the outer cover 11 to move towards the hose 2 direction. At this time, the valve stem 10 slides through the slider 13 and the chute 12 of the inclined surface, so that the valve stem 10 moves towards the outside of the adjustable valve 1. At this time, the valve hole 6 can be opened, and then the fluid can flow bidirectionally between the adjustable valve 1 and the hose 2.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit the protection scope of the present utility model. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present utility model.
