Abstract

This utility model discloses an anti-jamming self-lubricating valve, relating to the field of valve technology. The utility model includes a valve body, with a valve stem rotatably connected to the top of the valve body. A ball is fixedly connected to the bottom end of the valve stem, and a handle is fixedly connected to the top of the valve stem. A lubrication mechanism is provided inside the valve body, including an oil tank fixedly connected to the outer circumference of the valve body. This utility model utilizes the cooperation between components such as the oil tank, the extrusion plate, and the oil outlet in the lubrication mechanism. Rotating the handle drives the valve stem to rotate, pushing the push rod to rotate and extruding the force-bearing rod, thereby discharging lubricating oil from the oil tank into the lubrication chamber.

This design achieves self-lubrication during valve use, effectively preventing jamming caused by friction or environmental factors.

Description

Technical Field

[0001] This utility model belongs to the field of valve technology, and in particular relates to an anti-jamming self-lubricating valve. Background Technology

[0002] A valve is a device that controls the flow of fluids (such as liquids, gases, and steam). It is typically used in piping systems to control, regulate, or shut off fluid flow. The basic functions of a valve include starting, stopping, regulating flow rate, switching flow direction, and reducing pressure.

[0003] According to a public disclosure (publication number: CN 215673819U), a valve includes a pipeline with connecting flanges at both ends. A valve body is mounted on the pipeline. The valve body is a rectangular box with both ends connected to the pipeline. A hydraulic rod is mounted on the upper end of the valve body, extending out of the valve body and connecting to an external hydraulic device. A valve is mounted on the lower end of the hydraulic rod. When the hydraulic rod extends downward, it can drive the valve to move downward, thereby blocking the pipeline.

[0004] In the aforementioned application, the valve body and valve components cooperate with each other, making it easy for the valve body to jam or wear under long-term use or extreme working conditions, and it is difficult to solve the self-lubrication function, which leads to the internal components of the valve body being prone to jamming and wear. Therefore, we propose an anti-jamming self-lubricating valve. Utility Model Content

[0005] The purpose of this invention is to provide a self-lubricating valve that prevents jamming. The lubricating oil is discharged from the oil tank and flows into the lubrication chamber, reducing valve stem friction, reducing wear, and preventing jamming, thus solving the existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is an anti-jamming self-lubricating valve, including a valve body, a valve stem that is rotatably connected through the top of the valve body, a ball that is fixedly connected to the bottom end of the valve stem, a handle that is fixedly connected to the top of the valve stem, and a lubrication mechanism that is provided inside the valve body.

[0008] The lubrication mechanism includes an oil tank, which is fixedly connected to the outer circumferential surface of the valve body. A force-bearing rod is slidably connected through the inside of the oil tank. A pressing plate is fixedly connected to one end of the force-bearing rod near the inside of the oil tank. A lubrication chamber is opened inside the valve body. A push rod is fixedly connected to the circumferential surface of the valve stem. An oil outlet hole is opened on the inner circumferential surface of the oil tank.

[0009] Furthermore, a return spring is fixedly connected to the inner circumferential surface of the oil tank. The end of the return spring away from the inner circumferential surface of the oil tank is fixedly connected to the circumferential surface of the force-bearing rod. The purpose of this is to ensure that the force-bearing rod can automatically reset and reduce manual intervention.

[0010] Furthermore, the top of the oil tank is provided with a filling hole, and a sealing plug is slidably connected inside the filling hole. The purpose of this is to ensure that the user can replenish the lubricating oil inside the oil tank through the filling hole.

[0011] Furthermore, there are two of the force-bearing rod, push rod, and return spring, which are symmetrical to each other along the vertical central axis of the valve body. One end of the force-bearing rod is located on the displacement trajectory of the push rod, the purpose of which is to ensure that the rotation of the push rod can compress the force-bearing rod.

[0012] Furthermore, the valve body is provided with an application mechanism, which includes a chute. The chute is located inside the lubrication chamber. A movable plate is slidably connected inside the chute. An application brush is fixedly connected to the side of the movable plate. A movable rod is fixedly connected to the top of the movable plate. The purpose of this is to ensure that the lubricating oil can be applied evenly and to avoid lubricating oil accumulation.

[0013] Furthermore, a compression spring is fixedly connected inside the slide groove, and the end of the compression spring away from the inside of the slide groove is fixedly connected to the bottom of the moving plate. The purpose of this is to ensure that the moving plate can automatically reset and reduce manual intervention.

[0014] Furthermore, the top of the movable rod is located on the displacement trajectory of the push rod, the purpose of which is to ensure that the rotation of the push rod can compress the movable rod.

[0015] This utility model has the following beneficial effects:

[0016] This invention utilizes the interplay between components such as the oil tank, extrusion plate, and oil outlet of the lubrication mechanism. Rotating the handle drives the valve stem to rotate, which in turn pushes the push rod to rotate and compresses the force-bearing rod, thereby discharging lubricating oil from the oil tank into the lubrication chamber. This reduces valve stem friction, lowers wear, and prevents jamming. When the push rod leaves, the force-bearing rod is reset by a return spring, stopping the oil supply. This design achieves a self-lubricating effect when using the valve, effectively preventing jamming caused by friction or environmental factors.

[0017] This invention utilizes the coordinated operation of components such as the sliding groove, application brush, and compression spring in the application mechanism. The rotating push rod presses against the moving rod, causing the moving plate and application brush to move downwards, evenly applying lubricating oil to the valve stem surface. After the push rod moves away, the compression spring returns to its original position, and the application brush performs a second application, enhancing the lubrication effect. This design achieves even application of lubricating oil, effectively preventing lubricating oil buildup and thus ensuring proper lubrication.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5This utility model is an anti-jamming self-lubricating valve, including a valve body 1, a valve stem 2 that is rotatably connected through the top of the valve body 1, a ball 3 that is fixedly connected to the bottom end of the valve stem 2, a handle 4 that is fixedly connected to the top of the valve stem 2, and a lubrication mechanism 5 that is provided inside the valve body 1.

[0029] The lubrication mechanism 5 includes an oil tank 51, which is fixedly connected to the outer circumferential surface of the valve body 1. A force-bearing rod 52 is slidably connected through the inside of the oil tank 51. A pressing plate 53 is fixedly connected to one end of the force-bearing rod 52 near the inside of the oil tank 51. A lubrication chamber 54 is opened inside the valve body 1. A push rod 55 is fixedly connected to the circumferential surface of the valve stem 2. An oil outlet hole 59 is opened on the inner circumferential surface of the oil tank 51.

[0030] As shown in the figure, a return spring 56 is fixedly connected to the inner circumferential surface of the oil tank 51. The end of the return spring 56 away from the inner circumferential surface of the oil tank 51 is fixedly connected to the circumferential surface of the force rod 52. The purpose is to ensure that the force rod 52 can automatically reset and reduce manual intervention.

[0031] As shown in the figure, the top of the oil tank 51 is provided with an oil filling hole 57, and a sealing plug 58 is slidably connected inside the oil filling hole 57. The purpose is to ensure that the user can replenish the lubricating oil inside the oil tank 51 through the oil filling hole 57.

[0032] As shown in the figure, there are two force rods 52, push rods 55 and return springs 56, which are symmetrical to each other along the vertical central axis of valve body 1. One end of the force rod 52 is located on the displacement trajectory of the push rod 55. The purpose is to ensure that the rotation of the push rod 55 can squeeze the force rod 52.

[0033] As shown in the figure, the valve body 1 is equipped with a coating mechanism 6. The coating mechanism 6 includes a chute 61, which is opened inside the lubrication chamber 54. A movable plate 62 is slidably connected inside the chute 61. A coating brush 63 is fixedly connected to the side of the movable plate 62, and a movable rod 64 is fixedly connected to the top of the movable plate 62. The purpose is to ensure that the lubricating oil can be evenly coated and to avoid the accumulation of lubricating oil.

[0034] As shown in the figure, a compression spring 65 is fixedly connected inside the slide 61. One end of the compression spring 65 away from the inside of the slide 61 is fixedly connected to the bottom of the moving plate 62. The purpose of this is to ensure that the moving plate 62 can automatically reset and reduce manual intervention.

[0035] As shown in the figure, the top of the moving rod 64 is located on the displacement trajectory of the push rod 55. The purpose of this is to ensure that the rotation of the push rod 55 can compress the moving rod 64.

[0036] A specific application of this embodiment is as follows: When the handle 4 is rotated to drive the ball 3 through the valve stem 2 to use the valve body 1, the valve stem 2 rotates and drives the push rod 55 to rotate. The rotation of the push rod 55 compresses the force rod 52, and the force rod 52 enters the oil tank 51 under force, which in turn drives the extrusion plate 53 to apply pressure to the inside of the oil tank 51, so that the lubricating oil inside the oil tank 51 is discharged through the oil outlet 59, and then the lubricating oil flows into the lubrication chamber 54, releasing lubricating oil to the friction surface of the valve stem 2, reducing friction, reducing wear and preventing jamming. When the push rod 55 leaves one end of the force rod 52, the force rod 52 is reset by the return spring 56, thereby stopping the supply of lubricating oil.

[0037] As the push rod 55 rotates, it presses against the moving rod 64, causing the moving rod 64 to move the moving plate 62 inside the slide groove 61. The movement of the moving plate 62 causes the application brush 63 to move downwards. The moving application brush 63 pushes and applies lubricant inside the lubrication chamber 54. At the same time, it cooperates with the rotating valve rod 2 to evenly apply lubricant to the surface of the valve rod 2. With the continuous rotation of the push rod 55, when the push rod 55 leaves the top of the moving rod 64, it is reset by the elasticity of the compression spring 65, which drives the application brush 63 to apply a second coat, improving the application effect.
