Description

Technical Field

[0001] The utility model relates to the technical field of one-way valve design, in particular to a one-way valve with a protective installation structure. Background Art

[0002] The basic function of a check valve is to allow fluid or gas to flow freely in one direction while blocking or restricting flow in the opposite direction. This type of valve is very common in hydraulic and pneumatic systems to control the flow direction of the fluid and protect the system from reverse pressure.

[0003] An existing Chinese patent (publication number CN205824293U) discloses a one-way valve, which has a structure that makes the movement of the key components, the spring and the inner core of the one-way valve, which affect the control effect of the fluid more stable, so that the one-way valve can conduct the fluid more quickly and reliably, and has a better sealing effect on the fluid cutoff. The one-way valve has the advantages of simple structure, stable and reliable operation, and easy replacement.

[0004] The one-way valve of the above patent achieves an improvement in its shutoff sealing effect by making the spring and the one-way valve run more smoothly. However, the one-way valve of the above patent cannot protect the inner core of the one-way valve when in use. In actual application, under a specific pressure, the one-way valve will open to allow fluid flow, but if the pressure is too high or the air pressure is too large, it may cause damage to the valve. Therefore, the valve design needs to be able to withstand the maximum working pressure and flow while avoiding damage due to pressure shock. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and provide a one-way valve with a protective installation structure.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a one-way valve with a protective installation structure, comprising a one-way valve housing and a connecting shell fixedly connected to the one-way valve housing, wherein the connecting shell is connected to a protective component;

[0007] The protection component includes a leakage net, a connecting column is fixedly connected to the leakage net, a sliding ring is fixedly connected to the connecting column, a connecting plate is fixedly connected to the sliding ring, a rotating part is fixedly connected to the end of the connecting plate away from the sliding ring, a rotating shaft is rotatably connected to the rotating part, and the rotating shaft is rotatably connected to the connecting shell.

[0008] As a preferred embodiment, four connecting plates and four rotating members are provided, and the four rotating members are rotatably connected to rotating shafts, and the first blocking plate and the second blocking plate are rotatably connected to the rotating shafts on the rotating members, respectively.

[0009] The technical effect of adopting the above further solution is: by providing a blocking plate, in which the first blocking plate is slidably connected to the second blocking plate, when the air pressure is too high, the first blocking plate will slide into the second blocking plate to seal the fixed ring and cut off the airflow in time.

[0010] As a preferred implementation, the first blocking plate is slidably connected to the second blocking plate.

[0011] The technical effect of adopting the above further solution is: by arranging the first blocking plate to be slidably connected to the second blocking plate, the fixing ring is blocked.

[0012] As a preferred embodiment, a sliding groove is provided on the connecting shell, the connecting column is slidably connected in the sliding groove on the connecting shell, a fixing ring is fixedly connected to the connecting shell, and the fixing ring is fixedly connected to the one-way valve housing.

[0013] The technical effect of adopting the above further solution is: by providing a sliding groove on the connecting shell, the movement of the connecting column is facilitated to avoid it being stuck on the connecting shell and unable to move, resulting in the inability to slide the first blocking plate into the second blocking plate, affecting the effect of cutting off the airflow.

[0014] As a preferred embodiment, a conical block is fixedly connected to one end of the connection shell away from the leakage net, a blocking bead is clamped in the conical block, and an interception box is fixedly connected to one side of the conical block close to the leakage net.

[0015] The technical effect of adopting the above further scheme is: by providing an interception box, the blocking beads are prevented from falling off. When in use, when airflow enters, the blocking beads will be pushed away by the conical block. When the airflow refluxes, the blocking beads will re-block the conical block to achieve the effect of preventing its reflux.

[0016] As a preferred embodiment, the sliding ring is slidably connected to the connecting shell, and the blocking bead is rollingly connected in the interception box.

[0017] The technical effect of adopting the above further solution is: by providing an interception box, a guiding effect is played on the blocking beads to prevent them from being unable to be re-stuck in the conical block.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] 1. In the utility model, a protective component is provided. When the air pressure in the one-way valve is too large, the air pressure will drive the leakage net to slide in the connecting shell toward the side close to the fixed ring, drive the connecting column to slide on the connecting shell, and the connecting column will then drive the sliding ring and the connecting plate to slide on the connecting shell, and the connecting plate will drive the rotating member to move away from the first blocking plate. Since the rotating member is rotatably connected with a rotating shaft, when the rotating member moves away from the first blocking plate, it will drive the end of the rotating member close to the first blocking plate to rotate inward, so that the second blocking plates at the upper and lower ends are driven to close, and the first blocking plate is driven to slide into the second blocking plate to achieve the blocking of the fixed ring. At this time, the airflow is blocked in time, which can prevent the airflow or water flow from continuing to flow in the one-way valve to damage the internal components of the one-way valve.

[0020] 2. In the utility model, an interception box is provided to prevent the blocking beads from falling off. When in use, when airflow enters, the blocking beads will be pushed away from the conical block. When the airflow flows back, the blocking beads will re-block the conical block to achieve the effect of preventing the airflow from flowing back. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example

[0030] This embodiment provides a technical solution: Figures 1 to 4 As shown, a one-way valve with a protective installation structure comprises a one-way valve housing 1 and a connecting shell 2 fixedly connected to the one-way valve housing 1, and a protective component 3 is connected to the connecting shell 2;

[0031] like Figure 1 As shown, the protection component 3 includes a leakage net 38, a connecting column 33 is fixedly connected to the leakage net 38, a sliding ring 32 is fixedly connected to the connecting column 33, a connecting plate 34 is fixedly connected to the sliding ring 32, a rotating member 35 is fixedly connected to one end of the connecting plate 34 away from the sliding ring 32, a rotating shaft 31 is rotatably connected to the rotating member 35, and the rotating shaft 31 is rotatably connected to the connecting shell 2;

[0032] like Figure 1 , Figure 3 As shown, by providing a protective component 3, when the air pressure in the one-way valve is too high, the air pressure will drive the leakage net 38 to slide in the connecting shell 2 toward the side close to the fixed ring 4, drive the connecting column 33 to slide on the connecting shell 2, and the connecting column 33 will then drive the sliding ring 32 and the connecting plate 34 to slide on the connecting shell 2, and the connecting plate 34 will drive the rotating member 35 to move away from the end of the first blocking plate 36. Since the rotating member 35 is rotatably connected with the rotating shaft 31, when the rotating member 35 moves away from the end of the first blocking plate 36, it will drive the end of the rotating member 35 close to the first blocking plate 36 to rotate inward, so that the second blocking plates 37 at the upper and lower ends are driven to close, and the first blocking plate 36 is driven to slide into the second blocking plate 37 to achieve the blocking of the fixed ring 4. At this time, the airflow is blocked in time, which can prevent the airflow or water flow from continuing to flow in the one-way valve to damage the internal components of the one-way valve;

[0033] Furthermore, if Figure 1 , Figure 3 As shown, four connecting plates 34 and rotating members 35 are provided, and the four rotating members 35 are rotatably connected with rotating shafts, and the rotating shafts on the rotating members 35 are rotatably connected with the first blocking plate 36 and the second blocking plate 37, respectively. By providing blocking plates, the first blocking plate 36 is slidably connected in the second blocking plate 37. When the air pressure is too high, the first blocking plate 36 will slide into the second blocking plate 37 to achieve blocking of the fixing ring 4 and cut off the airflow in time.

[0034] like Figure 1 as well as Figure 3 As shown, the first blocking plate 36 is slidably connected to the second blocking plate 37, and the first blocking plate 36 is slidably connected to the second blocking plate 37 to achieve blocking of the fixing ring 4;

[0035] like Figure 4 As shown, a sliding groove is provided on the connecting shell 2, and the connecting column 33 is slidably connected in the sliding groove on the connecting shell 2. A fixing ring 4 is fixedly connected to the connecting shell 2, and the fixing ring 4 is fixedly connected to the one-way valve housing 1. The sliding groove is provided on the connecting shell 2 to facilitate the movement of the connecting column 33, so as to avoid it being stuck on the connecting shell 2 and unable to move, so that the first blocking plate 36 cannot slide into the second blocking plate 37, which affects the airflow cutoff effect;

[0036] In the above solution, there is still a problem that the blocking bead 22 may be stuck and cannot be reset when the water flows back. Figure 4 As shown, a conical block 21 is fixedly connected to one end of the connection shell 2 away from the leakage net 38, a blocking bead 22 is clamped in the conical block 21, and an interception box 23 is fixedly connected to one side of the conical block 21 close to the leakage net 38. The interception box 23 is provided to prevent the blocking bead 22 from falling off. When in use, when airflow enters, the blocking bead 22 will be pushed away from the conical block 21, and when the airflow flows back, the blocking bead 22 will re-block the conical block 21 to achieve the effect of preventing its backflow;

[0037] The sliding ring 32 is slidably connected to the connecting shell 2, and the blocking bead 22 is rollingly connected in the interception box 23. The interception box 23 is provided to guide the blocking bead 22 to prevent it from being unable to be re-stuck in the conical block 21.

[0038] Working principle:

[0039] like Figure 1-4 As shown: during use, when the air pressure in the one-way valve is too high, the air pressure will drive the leakage net 38 to slide in the connecting shell 2 toward the side close to the fixed ring 4, driving the connecting column 33 to slide on the connecting shell 2, and the connecting column 33 will then drive the sliding ring 32 and the connecting plate 34 to slide on the connecting shell 2, and the connecting plate 34 will drive the rotating member 35 to move away from the end of the first blocking plate 36. Since the rotating member 35 is rotatably connected with the rotating shaft 31, when the rotating member 35 moves away from the end of the first blocking plate 36, it will drive the end of the rotating member 35 close to the first blocking plate 36 to rotate inward, so that the second blocking plates 37 at the upper and lower ends are driven to close, and the first blocking plate 36 is driven to slide into the second blocking plate 37 to achieve the blocking of the fixed ring 4. At this time, the airflow is blocked in time, which can prevent the airflow or water flow from continuing to circulate in the one-way valve and causing damage to the internal components of the one-way valve.
