[0032] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0033] Example 1
[0034] like Figures 1 to 3 As shown, a reversible one-way valve includes a valve body 1 with two open ends, and limit ring platforms 2 are symmetrically arranged at both ends of the valve body 1. An adjusting part is slidably arranged between the two limit ring platforms 2, and a blocking block 3 for blocking the hollow part in the middle of the limit ring platform 2 is arranged on the end surface of the adjusting part facing the two limit ring platforms 2, and the blocking block 3 is elastically connected to the end surface of the adjusting part.
[0035] The beneficial effects of this embodiment are: the adjustment part slides to adjust the distance between the blocking block 3 and the limiting ring platform 2, and elastically blocks the limiting ring platform 2 to realize the non-return function; the adjustment part can block either side to achieve the reversal of the non-return function, and when adjusting the distance between the blocking block 3 and the limiting ring platform 2, the elastic sealing force can be changed, and the usage is flexible.
[0036] Specifically, Figure 2As shown, both ends of the valve body 1 are provided with internal threads. The valve body 1 is installed on the pipeline. When the medium needs to be transmitted from left to right, the sliding adjustment part approaches the left limit ring platform 2, and the left blocking block 3 blocks the left limit ring platform 2, and the right blocking block 3 is away from the right limit ring platform 2, so the right limit ring platform 2 remains open; during the process of the pipeline transmitting the medium from left to right, the medium periodically pushes the left blocking block 3 away, and after the medium enters the valve body 1, the elastic connection pushes the left blocking block 3 to reset and block the left limit ring platform 2, so as to achieve non-return;
[0037] When the medium needs to be transmitted from right to left, the adjusting part is slid to the right, so that the right blocking block 3 blocks the right limiting ring platform 2, and the left limiting ring platform 2 remains open;
[0038] When the check function is not needed, the adjusting portion is adjusted to the middle of the valve body 1 , and the blocking blocks 3 on both sides do not contact the limiting ring 2 .
[0039] Example 2
[0040] like Figures 2 to 3 As shown, preferably, on the basis of Embodiment 1, the regulating part is a main disk 4, the main disk 4 is coaxial with the valve body 1, and the main disk 4 is provided with a plurality of water holes 5 around the axis.
[0041] Preferably, the two end surfaces of the main plate 4 are symmetrically fixed with sliding sleeves 6, and sliding posts 7 are slidably installed in the sliding sleeves 6. The sliding direction of the sliding post 7 is coaxial with the main plate 4. One end of the sliding post 7 extends out of the sliding sleeve 6 and points to the limiting ring platform 2 on the side where it is located and is fixed to the blocking block 3.
[0042] An elastic element 8 is installed in the sliding sleeve 6 , one end of the elastic element 8 abuts against the end surface of the main disk 4 , and the other end abuts against one end of the sliding column 7 facing the main disk 4 .
[0043] The beneficial effects of the preferred solution in the above embodiment are as follows: the main disc 4 slides in the valve body 1, driving the block 3 on either side close to the limit ring 2, the elastic element 8 pushes the block 3 to block the limit ring 2, and after the transmission medium pushes the block 3 away from the outside, the elastic element 8 can be reset in time;
[0044] Specifically, Figure 2 As shown, the elastic element 8 is a coil spring. When the block 3 is closer to the limiting ring 2 on one side, the elastic element 8 on that side will be compressed more, the stored elastic potential energy will be stronger, and the medium in the pipeline will be more difficult to push the block 3 away from this direction, thereby achieving adjustable sealing force.
[0045] In addition, the elastic element 8 is placed in the sliding sleeve 6, and the sliding sleeve 6 can guide the elastic element 8 when it is extended and retracted to prevent the elastic element 8 from deflecting;
[0046] If there are particles, floccules or other impurities in the transmitted medium, the sleeve 6 can also protect the elastic element 8 to prevent the impurities from entering the sleeve 6 and being hooked by the elastic element 8, thereby preventing the elastic element 8 from being compressed.
[0047] Example 3
[0048] like Figure 1 to Figure 2 As shown, preferably, on the basis of Embodiment 1-2, a slide groove 9 is provided on the inner wall of the valve body 1, the length direction of the slide groove 9 is parallel to the axis of the main disk 4, and a threaded rod 10 is rotatably installed in the slide groove 9;
[0049] A protrusion 11 is fixedly connected to the outer circumferential wall of the main plate 4 , and the protrusion 11 extends into the sliding groove 9 and is threadedly connected to the threaded rod 10 .
[0050] Preferably, one end of the threaded rod 10 extends out of the valve body 1 to the outside and is provided with a positioning notch 12 .
[0051] The beneficial effects of the preferred solution in the above embodiment are: the threaded rod 10 drives the main plate 4 to move, adjusts the distance between the blocking block 3 and the limiting ring 2, and the threaded rod 10 controls the distance accurately, and has a self-locking effect due to the thread angle, preventing the main plate 4 from moving under the impact of the transmission medium;
[0052] Specifically, the positioning notch 12 cuts the end of the threaded rod 10 into a rectangle, which is convenient for clamping with the valve handle. The valve body 1 is in a state without a valve handle when leaving the factory, preventing unauthorized personnel from changing the state of the valve body 1.
[0053] As a parallel technical solution of this embodiment, the threaded rod 10 can also be replaced by an electric telescopic rod, the axis of the electric telescopic rod is parallel to the axis of the main plate 4, and the telescopic end of the electric telescopic rod is fixedly connected to the protrusion 11 to realize the function of pushing the main plate 4.
[0054] Example 4
[0055] like Figures 2 to 3 As shown, preferably, on the basis of embodiments 1-3, the end of the sliding column 7 pointing to the limiting ring platform 2 is also fixedly connected to a tray 13, and the end of the tray 13 facing the limiting ring platform 2 is fixedly connected to the blocking block 3.
[0056] Preferably, the tray 13 and the sliding column 7 are manufactured in one piece.
[0057] Preferably, the blocking block 3 is made of rubber.
[0058] Preferably, the side of the blocking block 3 facing the limiting ring 2 is a conical surface.
[0059] The beneficial effects of the preferred solution in the above embodiment are: the block 3 is fixed on the tray 13, because the area of the tray 13 is larger than the block 3, so the block 3 is better installed to prevent the block 3 from deforming too much;
[0060] Specifically, a convex column is fixed on the end surface of the tray 13, and the convex column is inserted into the rubber block 3 for fixing to prevent the block 3 from shaking;
[0061] Specifically, the tray 13 and the sliding column 7 are both made of metal, and the integrated manufacturing has high strength, is not easy to be damaged, and has low cost.
[0062] Example 5
[0063] like Figure 2 As shown, preferably, on the basis of embodiments 1-4, the distance between the conical surfaces of the two blocking blocks 3 is smaller than the distance between the two limiting ring platforms 2.
[0064] The beneficial effect of adopting the preferred solution in the above embodiment is that the two blocking blocks 3 can only block the limiting ring platform 2 on either side or not block both sides, but cannot block the limiting ring platforms 2 on both sides at the same time, thereby avoiding misoperation leading to complete closure of the pipeline.
[0065] Finally, 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 purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
