Description

Technical Field

[0001] This utility model relates to the field of fluid control valve technology, specifically a low-resistance, labor-saving control valve for opening and closing. Background Technology

[0002] In fluid control systems, valves are key components that play a vital role in regulating, controlling, cutting off, or guiding fluid flow. However, traditional valves are often designed with high resistance and require significant effort to open and close, which not only affects the overall efficiency of the fluid system but also increases operational difficulty and energy consumption.

[0003] In traditional methods, fluid control valves often require considerable force to close, overcoming the resistance generated by the fluid flow in order to completely shut off the valve body and pipeline. This process is quite laborious, resulting in low work efficiency and the inability to close the control valve in a timely manner, which can lead to certain economic losses. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a low-resistance, labor-saving control valve that solves the problem that traditional methods require significant force to overcome the large resistance generated when fluid flows through in order to close the valve body pipeline.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a low-resistance, labor-saving control valve, including a valve body pipeline, a control valve body fixedly connected to the middle of the valve body pipeline, and a labor-saving opening and closing component provided on the control valve body, the labor-saving opening and closing component being used to open and close the valve body pipeline.

[0008] The labor-saving opening and closing assembly includes a gear plate, rubber ring, spring retaining groove, spiral spring, waterproof thrust bearing, gear, worm gear, handle, and protective housing;

[0009] The slotted plate in the labor-saving opening and closing assembly is fixedly connected to the inner wall of the valve body pipeline. The slotted plate of the valve body pipeline has a flow groove, and the gear plate has the same flow groove. When the two sets of flow grooves overlap, the resistance will be reduced. The gear plate is set in the control valve body.

[0010] The spring fixing groove is opened on one side of the inner wall of the control valve body, and the spiral spring is sleeved in the spring fixing groove. The spiral spring is a spiral spring wound in a conical shape, which has the advantages of high extensibility and strong elasticity.

[0011] Preferably, one side of the waterproof thrust bearing is fixedly connected to the gear plate, and the other rotating surface of the waterproof thrust bearing is fixedly connected to the spiral spring.

[0012] Preferably, the rubber ring is fixedly connected to the gear plate, a sealing sliding groove is provided on the inner wall of the control valve body, the rubber ring is adapted to the sealing sliding groove, and a gear groove is provided in the valve body pipeline.

[0013] Preferably, a gear shaft is rotatably connected inside the gear groove, the gear is fixedly sleeved on the outer surface of the gear shaft, and the gear meshes with the gear plate.

[0014] Preferably, one end of the gear shaft rotatably extends through the outer surface of the control valve body and is fixedly inserted into the worm gear, on which a worm is meshed.

[0015] Preferably, the handle is rotatably connected to the protective housing, the handle's shaft is fixedly inserted into the worm gear, and the protective housing is fixedly installed on the valve body pipeline.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a low-resistance, labor-saving control valve for opening and closing, which has the following advantages:

[0018] 1. This low-resistance, labor-saving control valve operates by manually rotating the handle. The handle's shaft drives the worm gear and the gear on the gear shaft to rotate simultaneously. The rotation of the gear drives the gear plate to rotate, and as the gear plate rotates, its flow groove gradually shifts away from the flow groove on the trough plate. At this point, the previously rotated handle experiences minimal resistance. However, due to the shift between the trough plate and the gear plate, the resistance of the fluid in the valve body increases. The spiral spring is compressed under this force until the gear plate moves to the point where the rubber ring fits into the trough plate, at which point the valve closes. This mechanism makes closing the valve easier because it utilizes fluid resistance. Minimal force is required when manually rotating the handle, improving the convenience and efficiency of valve opening and closing. This avoids the problem of traditional methods requiring significant force to overcome the large resistance generated by the fluid flow to close the valve.

[0019] 2. This low-resistance, labor-saving control valve utilizes the self-locking and deceleration properties of the worm gear and worm shaft meshing. This deceleration makes it easier to rotate the handle manually, while the self-locking property effectively ensures the stability of the valve body's opening and closing, preventing the valve from being forced open due to excessive fluid resistance.

If the first and second are mentioned, they are only for the purpose of distinguishing technical features and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] Please see Figure 1-3 This utility model provides a new technical solution: a low-resistance, labor-saving control valve, including a valve body pipe 1, a control valve body 2 fixedly connected to the middle of the valve body pipe 1, and a labor-saving opening and closing component provided on the control valve body 2, which is used to open and close the valve body pipe 1.

[0029] The labor-saving opening and closing assembly includes a gear plate 4, a rubber ring 6, a spring fixing groove 7, a spiral spring 8, a waterproof thrust bearing 9, a gear 12, a worm gear 13, a handle 15, and a protective shell 16.

[0030] The slotted plate 3 in the labor-saving opening and closing assembly is fixedly connected to the inner wall of the valve body pipe 1. The slotted plate 3 of the valve body pipe 1 is provided with a flow groove, and the gear plate 4 is provided with the same flow groove. When the two sets of flow grooves overlap, the resistance will be reduced. The gear plate 4 is set inside the control valve body 2.

[0031] The spring fixing groove 7 is opened on one side of the inner wall of the control valve body 2, and the spiral spring 8 is sleeved in the spring fixing groove 7. The spiral spring 8 is a spiral spring wound in a conical shape, which has the advantages of high extensibility and strong elasticity.

[0032] Furthermore, one side of the waterproof thrust bearing 9 is fixedly connected to the gear plate 4, and the other rotating surface of the waterproof thrust bearing 9 is fixedly connected to the spiral spring 8.

[0033] Furthermore, the rubber ring 6 is fixedly connected to the gear plate 4, and the inner wall of the control valve body 2 is provided with a sealing sliding groove 5. The rubber ring 6 is adapted to the sealing sliding groove 5, and the valve body pipe 1 is provided with a gear groove 10.

[0034] Furthermore, a gear shaft 11 is rotatably connected inside the gear groove 10, and a gear 12 is fixedly sleeved on the outer surface of the gear shaft 11. The gear 12 meshes with the gear plate 4.

[0035] Furthermore, one end of the gear shaft 11 rotates through the outer surface of the control valve body 2 and is fixedly inserted into the worm gear 13, on which a worm 14 is meshed.

[0036] Furthermore, the handle 15 is rotatably connected to the protective housing 16, the shaft of the handle 15 is fixedly inserted into the worm gear 14, and the protective housing 16 is fixedly installed on the valve body pipeline 1.

[0037] Furthermore, during use, manually rotating the handle 15 causes the handle 15's shaft to drive the worm gear 13 and the gear 12 on the gear shaft 11 to rotate simultaneously via the worm 14. The rotation of the gear 12 drives the gear plate 4 to rotate. As the gear plate 4 rotates, its flow groove gradually shifts away from the flow groove on the groove plate 3. At this point, the previously rotated handle 15 will not experience much resistance. However, due to the shift between the groove plate 3 and the gear plate 4, the resistance of the fluid in the valve body pipe 1 increases. The spiral spring 8 is then compressed by this force until the gear plate 4 moves to fit the rubber ring 6 into the groove plate 3. At this point, the valve is closed. The operation of this structure makes closing the valve body pipe 1 easier because the valve's closure utilizes fluid resistance. When manually rotating the handle 15, it requires less force to close, improving the convenience and efficiency of opening and closing the valve body pipe. This makes operation easier and less strenuous, avoiding the problem of needing greater force to overcome the significant resistance generated by the fluid flow in traditional methods to close the valve body pipe.

[0038] Furthermore, due to the self-locking and deceleration properties of the meshing of the worm gear 13 and the worm 14, the deceleration property makes it easier to rotate the handle 15 when it is manually rotated, while the self-locking property ensures the stability of the opening and closing of the control valve body 2, avoiding the problem of excessive fluid resistance causing the valve to be forced open.

[0039] Working principle: When in use, the handle 15 is manually rotated. The shaft of the handle 15 will drive the worm wheel 13 and the gear 12 on the gear shaft 11 to rotate simultaneously through the worm gear 14. When the gear 12 rotates, it can drive the gear plate 4 to rotate. When the gear plate 4 rotates, the flow groove on it will gradually be misaligned with the flow groove on the groove plate 3. At this time, the handle 15 will not feel much resistance when rotated. However, due to the misalignment of the groove plate 3 and the gear plate 4, the resistance of the fluid in the valve body pipe 1 increases. At this time, the spiral spring 8 will be compressed by its force until the gear plate 4 moves to the rubber ring 6 and fits into the groove plate 3. At this time, the valve is closed.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
