Description

Technical Field

[0001] This utility model relates to the field of electric valve technology, and in particular to an electric valve with descaling function. Background Technology

[0002] An electric valve is a valve controlled by an electric actuator, thereby opening and closing the valve. An electric valve typically consists of an electric actuator and a valve connected together, and after installation and commissioning, it becomes an electric valve. Electric valves use electrical energy as power to activate the electric actuator, driving the valve to perform opening, closing, and regulating actions. This achieves the purpose of switching or regulating the media in the pipeline.

[0003] A search of Chinese patent CN208728227U reveals an electric valve with descaling function, comprising an electric valve body and a descaling device. The electric valve body includes a first pipe with an inlet at one end and an outlet at the other. A first motor is mounted on the first pipe, and a valve is mounted inside the first pipe and connected to the first motor. The descaling device is connected to the inlet. The descaling device includes a second pipe with a second motor mounted on it and a connecting shaft connected to the second motor. A first bevel gear is connected to one end of the connecting shaft. A support sleeve is mounted inside the second pipe, and a descaling brush assembly is sleeved on the support sleeve. A second bevel gear is mounted on the descaling brush assembly, and the first bevel gear meshes with the second bevel gear. The first motor and the second motor are electrically connected to a control terminal.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] The existing electric valve relies on a spring to push the descaling brush assembly towards the first pipe body to remove the dirt inside the first pipe body. However, the spring is prone to rusting in water, which affects the spring force and makes it difficult to continuously push the descaling brush assembly to move. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes an electric valve with descaling function. When the second motor is started, it drives the connecting rod to rotate, which in turn drives the first bevel gear to rotate, the second bevel gear to rotate, and the third bevel gear to rotate. The rotation of the second bevel gear drives the rotating rod to rotate, which in turn drives the disc to rotate, which in turn drives the descaling brush to rotate. The rotation of the third bevel gear drives the clamping block to move, which in turn drives the disc to move along the rotating rod. The descaling brush moves towards the main pipe while rotating, thus removing the dirt in the main pipe.

[0007] The technical solution to achieve the purpose of this utility model is: an electric valve with descaling function, including a main pipeline, a descaling pipe provided on one side of the main pipeline, a first support block fixedly connected to the inner wall of the descaling pipe, and further including;

[0008] Descaling mechanism, wherein the descaling mechanism is located inside the descaling pipe;

[0009] The descaling mechanism includes a rotating rod rotatably connected to a first support block. The rotating rod has a limiting protrusion and a disc slidably connected to it. An annular plate is fixedly connected to one side of the disc. Two extension plates are fixedly connected to one end of the annular plate. Descaling brushes are fixedly connected to one side of each of the two extension plates. A second bevel gear is keyed to one end of the rotating rod. A connecting rod is rotatably connected to the top of the descaling tube. A first bevel gear is keyed to the bottom end of the connecting rod. The first bevel gear meshes with the second bevel gear.

[0010] In some embodiments, a fixing frame is fixedly connected to the top of the descaling pipe, a second motor is fixedly connected to the top of the fixing frame, the output end of the second motor is fixedly connected to the top of the connecting rod, and a second flange is fixedly connected to both ends of the descaling pipe.

[0011] In some embodiments, the inner wall of the descaling pipe is fixedly connected to two second support blocks. The two second support blocks are jointly fixedly connected to a slide rod and jointly rotatably connected to a threaded rod. One end of the threaded rod passes through one of the second support blocks and is keyed to a third bevel gear. The third bevel gear meshes with the first bevel gear.

[0012] In some embodiments, a movable block is screwed onto the threaded rod, the movable block is slidably connected to the slide rod, a fixed rod is fixedly connected to one side of the movable block, a clamping block is fixedly connected to one end of the fixed rod, the clamping block is adapted to the disc, and the disc is slidably connected inside the clamping block.

[0013] In some embodiments, the two ends of the main pipeline are fixedly connected to a first flange, one of the first flanges is fixedly connected to one of the second flanges, the top of the main pipeline is fixedly connected to a first motor, and the output end of the first motor passes through the cylindrical outer wall of the main pipeline and is fixedly connected to a valve.

[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] Firstly, this utility model, through the setting of the descaling mechanism, starts the second motor, drives the connecting rod to rotate, drives the first bevel gear to rotate, drives the second bevel gear to rotate, drives the third bevel gear to rotate, the second bevel gear to rotate, drives the rotating rod to rotate, drives the disc to rotate, drives the descaling brush to rotate, the third bevel gear to rotate, drives the clamping block to move, drives the disc to move along the rotating rod, and the descaling brush moves towards the main pipe while rotating, removing the dirt in the main pipe;

[0016] Secondly, this utility model, through the setting of the threaded rod, the rotation of the third bevel gear drives the threaded rod to rotate, which in turn drives the moving block to move along the slide rod, drives the fixed rod to move, drives the clamping block to move, and drives the disc to move. At the same time, the limiting protrusion ensures that the disc follows the rotating rod to rotate, so that the descaling brush rotates on the inner wall of the main pipe during the movement, and thoroughly removes the dirt on the inner wall of the main pipe.

[0017] This solves the problem that existing springs are prone to rusting in water, which affects the spring's elasticity and makes it difficult to continuously push the descaling brush assembly. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0026] This utility model provides an improved electric valve with descaling function. The technical solution of this utility model is as follows:

[0027] like Figures 1-4As shown, an electric valve with descaling function includes a main pipe 1, a descaling pipe 2 on one side of the main pipe 1, a first support block 501 fixedly connected to the inner wall of the descaling pipe 2, and a descaling mechanism located inside the descaling pipe 2. The descaling mechanism includes a rotating rod 502 rotatably connected to the first support block 501, a limiting protrusion 503 on the rotating rod 502 to ensure that a disc 6 rotates with the rotating rod 502, and a disc 6 is slidably connected to it. An annular plate 601 is fixedly connected to one side of the disc 6, two extension plates 602 are fixedly connected to one end of the annular plate 601, and descaling brushes 603 are fixedly connected to one side of each of the two extension plates 602. A second bevel gear 5 is keyed to one end of the rotating rod 502, and the top of the descaling pipe 2 rotates... A connecting rod 301 is connected, and a first bevel gear 302 is keyed to the bottom end of the connecting rod 301. The first bevel gear 302 meshes with the second bevel gear 5. To reduce gear wear, the first bevel gear 302 and the second bevel gear 5 are self-lubricating gears. With the descaling mechanism set up, the second motor 3 is started, which drives the connecting rod 301 to rotate, drives the first bevel gear 302 to rotate, drives the second bevel gear 5 to rotate, drives the third bevel gear 7 to rotate, the second bevel gear 5 to rotate, drives the rotating rod 502 to rotate, drives the disc 6 to rotate, drives the descaling brush 603 to rotate, and the third bevel gear 7 to rotate, drives the clamping block 802 to move, drives the disc 6 to move along the rotating rod 502.
