Description

Technical Field

[0001] This utility model relates to the field of flow control valve technology, and more specifically, to a novel electro-proportional control valve. Background Technology

[0002] A proportional valve is a variable flow valve that can output a continuous flow range, providing regulated fluid flow from zero flow to the valve's maximum flow rate.

[0003] Existing technology discloses several patent documents for proportional electric control valves. Chinese patent application number CN202122253066.X discloses a proportional electric control valve, including a valve body, a plug disposed on the outer wall of the valve body, a pressure rod movably connected to the upper end of the plug, a screw movably connected to the upper end of the pressure rod, a stepper motor movably connected to the upper end of the screw, a plurality of electromagnets disposed inside the plug, and a baffle plate disposed inside the valve body. This device has the effect of flexibly controlling the inlet water flow while preventing seepage and leakage.

[0004] In the aforementioned patents, the control valve is leak-proof by means of a motor, which has a high operating cost and is also difficult to repair after damage, resulting in excessive operating costs. Therefore, we propose a new type of electro-proportional control valve. Utility Model Content

[0005] Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a novel electro-proportional control valve. This utility model uses the elastic action of a spring to position the slip ring, thereby allowing the insert ring to snap into the receiving groove. The insert ring also fixes the sealing ring, facilitating the sealing of the rotating shaft. When the rotating shaft rotates, the slide plate moves downward, and the movement of the spring compresses the spring, thus facilitating the spring to tightly seal the slip ring, further optimizing the sealing effect on the rotating shaft. The snap-fit ​​method reduces the cost of using the sealed rotating shaft.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] Example:

[0031] Please see Figure 1-Figure 4 A new type of electro-proportional control valve, including:

[0032] Control valve body 1;

[0033] Rotary shaft 3 is mounted on the control valve body 1;

[0034] The receiving groove 5 is formed on the rotating shaft 3;

[0035] A sealing mechanism is installed on the control valve body 1 and is connected to the rotating shaft 3.

[0036] In this embodiment, the rotating shaft 3 is for the purpose of opening the slot 4, and the receiving groove 5 is for the purpose of engaging with the sealing ring 6. The sealing mechanism facilitates the sealing of the rotating shaft 3. This utility model uses the elastic action of the spring 9 to position the slip ring 8, so that the insert ring 11 is engaged in the receiving groove 5, and the sealing ring 6 is fixed by the insert ring 11, which facilitates the sealing of the rotating shaft 3. When the rotating shaft 3 rotates, the slide plate 10 moves downward, and the movement of the spring 9 compresses the spring 9, which facilitates the spring 9 to tightly seal the slip ring 8, further optimizing the sealing effect of the rotating shaft 3. The engagement method reduces the cost of using the sealed rotating shaft 3.

[0037] Specifically, the sealing mechanism includes a sealing component and a positioning component, both of which are mounted on the control valve body 1 and are connected to each other.

[0038] In this embodiment, the sealing mechanism includes a sealing component and a positioning component. Both the sealing component and the positioning component are disposed on the control valve body 1 and are connected to each other.

[0039] Specifically, the sealing assembly includes a sealing ring 6, a slip ring 8, and a plug ring 11. The sealing ring 6 is movably inserted into the receiving groove 5, the slip ring 8 is movably inserted into the surface of the rotating shaft 3, and the plug ring 11 is fixedly connected to the bottom of the slip ring 8 and is movably inserted into the receiving groove 5.

[0040] In this embodiment, the sealing ring 6 is used to facilitate the sealing of the rotating shaft 3, and the slip ring 8 is used to facilitate the fixing of the insert ring 11. The rotating shaft 3 is sealed by the snap-fit ​​between the insert ring 11 and the receiving groove 5, and the sealing ring 6 is further sealed.

[0041] Specifically, the positioning assembly includes a protective shell 7, a spring 9, and a sliding plate 10. The protective shell 7 is fixedly connected to the control valve body 1, the spring 9 is fixedly connected to the slip ring 8, and the sliding plate 10 is slidably connected inside the protective shell 7, and the sliding plate 10 is fixedly connected to the spring 9.

[0042] In this embodiment, the protective shell 7 is designed to facilitate sliding cooperation with the slide plate 10. The elastic action of the spring 9 fixes the positions of the slide plate 10 and the slip ring 8, thereby facilitating the insertion ring 11 to be snapped into the receiving groove 5, which in turn facilitates the sealing ring 6 to perform a sealing function.

[0043] Specifically, a slot 4 is provided on the rotating shaft 3, and a plug rod 12 is fixedly connected to the bottom of the slide plate 10. The plug rod 12 is movably inserted into the slot 4. A connecting rod 13 is fixedly connected to the slide plate 10, and a rotating rod 14 is fixedly connected to the connecting rod 13.

[0044] In this embodiment, the slot 4 is provided to facilitate engagement with the insertion rod 12. Holding the rotating rod 14, press the rotating rod 14 downwards. The movement of the rotating rod 14 causes the connecting rod 13 to move downwards. The movement of the connecting rod 13 causes the sliding plate 10 to move downwards. The movement of the sliding plate 10 causes the insertion rod 12 to move downwards, thereby inserting the insertion rod 12 into the slot 4. Then, rotate the rotating rod 14, and the rotation of the rotating rod 14 causes the insertion rod 12 to rotate.

[0045] Specifically, three flanges 2 are fixedly connected to the side end of the control valve body 1.

[0046] In this embodiment, three flanges 2 are fixedly connected to the side end of the control valve body 1, and the flanges 2 and bolts facilitate the connection of external pipelines.

[0047] Working principle: When it is necessary to rotate the rotating shaft 3, hold the rotating rod 14 and press the rotating rod 14 downward. The movement of the rotating rod 14 drives the connecting rod 13 to move downward. The movement of the connecting rod 13 drives the sliding plate 10 to move downward. In turn, the movement of the sliding plate 10 drives the insertion rod 12 to move downward, so that the insertion rod 12 is inserted into the slot 4. Then rotate the rotating rod 14. The rotation of the rotating rod 14 drives the insertion rod 12 to rotate. The insertion rod 12 and the slot 4 are connected to facilitate the rotation of the slot 4.
