Description

Technical Field

[0001] This utility model relates to the field of electric hose valve technology, and in particular to an electric hose valve that is easy to maintain. Background Technology

[0002] In modern industry, when solid or liquid products containing abrasive substances such as particles, powders, fibers, and slurries are transported through pipelines, or when corrosive media are involved in chemical processes, hose valves are the best choice.

[0003] A patent website discloses a stable electric hose valve (CN211779122U), the key technical points of which are: it includes a valve body, the valve body has a three-way valve chamber inside, a rubber tube is arranged inside the valve chamber, the top opening of the valve body has a first protruding tube integrally formed with the valve body, the two side openings of the valve body have second protruding tubes integrally formed with the valve body, a top cover is detachably connected to the top of the first protruding tube, a support part is fixed to the top of the first protruding tube, a miniature electric push rod is fixed on the support part, a fixing rod is installed and fixed to the output shaft end of the miniature electric push rod, a first pressure block is connected to the bottom of the fixing rod, and a second pressure block is arranged inside the valve chamber of the valve body; the stable electric hose valve can realize electric opening and closing during use, thus extending the service life of the valve.

[0004] The above-mentioned technology uses an electric push rod to move the first pressure block and cooperate with the fixed second pressure block to clamp the hose, thereby completing the shut-off operation. However, the independent clamping of the hose by the first pressure block will change the clamping path of the hose, thus making the upper surface of the hose taut. Due to the characteristics of the hose, the tautness of the hose will make the clamping surface of the hose thinner during clamping. Although it can be resisted by the first pressure block, the elasticity of the upper surface of the hose will be reduced due to the thinning of the tautness, making it easier to be broken by the flow of the medium or to deepen the wear. At the same time, the above-mentioned technology is only convenient for the installation and removal of the electric push rod, but not convenient for maintenance of the valve body. Therefore, there is room for improvement. Utility Model Content

[0005] This invention provides an easy-to-maintain electric hose valve to solve the problems mentioned in the background art.

[0006] To address the aforementioned problems, this utility model provides an easy-to-maintain electric hose valve, comprising a housing, a hose, and a clamping mechanism. The housing consists of an upper housing and a lower housing, which are fixedly connected by bolts. The hose is disposed within the housing, which contains a clamping cavity. The clamping mechanism is located within the clamping cavity and consists of an upper clamping plate and a lower clamping plate. A through-hole bearing is located at the top of the upper housing, and a rotating column rotatably mounts within the bearing. The top of the rotating column is located outside the upper housing and is fixedly connected to a connector. The bottom end of the rotating column is located within the clamping cavity, and a threaded rod is threadedly connected to the rotating column. The bottom end of the threaded rod is connected to the upper clamping plate. Two clamping mechanisms are symmetrically positioned on the bottom side of the upper clamping plate. The first drive plate is located on the outer side of the tube, and several racks are provided on the outer side of the first drive plate. The lower clamping plate is located in the clamping cavity below the tube. Two second drive plates are symmetrically arranged at both ends of the lower clamping plate, located outside the first drive plate. The top of the second drive plate slides through the upper clamping plate and a limiting plate is fixed at the end. Several racks are provided in the middle and lower part of the inner side of the second drive plate. Two drive gears are symmetrically rotated in the upper housing between the first drive plate and the second drive plate, and the drive gears mesh with the racks in the first drive plate and the second drive plate. A connecting flange is fixed around the shaft seat at the top of the upper housing. A motor box is connected to the connecting flange by bolts. A motor is installed in the motor box, and the power shaft of the motor passes through the motor box and is inserted into the connector.

[0007] Preferably, four symmetrical arc-shaped limiting strips are fixedly provided on both sides of the upper housing, and two limiting grooves matching the arc-shaped limiting strips are provided at both ends of the upper clamping plate, and the limiting strips and limiting grooves are slidably connected.

[0008] Preferably, the upper and lower clamping plates have trapezoidal clamping blocks on their clamping surfaces facing the hose, and the top surface of the clamping blocks abuts against the outer surface of the hose.

[0009] Preferably, the first drive plate and the second drive plate have the same number of racks, and with the cooperation of the first drive plate and the second drive plate, the upper clamping plate and the lower clamping plate move along the same path, which is the radius of the hose.

[0010] Preferably, the top of the connector is provided with a hexagonal connection port, and the end of the motor's power shaft matches the hexagonal connection port.

[0011] The beneficial effects of adopting the above technical solutions are:

[0012] By moving the upper and lower clamps in opposite directions, the upper and lower sides of the hose are simultaneously compressed, thereby reducing the hose's tension and making it less prone to wear or breakage, thus extending its service life.

[0013] The upper and lower clamping plates move in opposite directions through the rack and pinion mechanism of the first and second drive plates, which is simple, stable and easy to maintain.

[0014] The connector in the connector is compatible with the motor's drive shaft, making it easy to install and remove the motor from the outside, which in turn facilitates motor maintenance and improves maintenance efficiency. Attached Figure Description

[0023] like Figure 1-4 In this embodiment, an easy-to-maintain electric hose valve includes a housing 1, a hose 2, and a clamping mechanism 3. The housing 1 is composed of an upper housing 11 and a lower housing 12, which are fixedly connected by bolts. The hose 2 is disposed in the housing 1. The housing 1 has a clamping cavity 13. The clamping mechanism 3 is disposed in the clamping cavity 13 of the housing 1. The clamping mechanism 3 is composed of an upper clamping plate 31 and a lower clamping plate 32. The upper housing 11 has a through-hole bearing 14 at its top. A rotating column 15 is rotatably disposed in the bearing 14. The top of the rotating column 15 is located outside the upper housing 11 and is fixedly connected to a connector 16. The bottom end of the rotating column 15 is located in the clamping cavity 13, and a threaded rod 17 is threadedly connected to the rotating column 15. The bottom end of the threaded rod 17 is connected to the upper clamping plate 31. Two first drive plates 311 are symmetrically disposed on the bottom side of the upper clamping plate 31, located outside the hose 2. The first drive plate 311 has several racks 33 on its outer side. The lower clamping plate 32 is located in the clamping cavity 13 below the rubber tube 2. The two ends of the lower clamping plate 32 are symmetrically provided with two second drive plates 321 located outside the first drive plate 311. The top end of the second drive plate 321 slides through the upper clamping plate 31 and is fixedly provided with a limiting plate 322 at its end. The middle and lower part of the inner side of the second drive plate 32 is provided with several racks 33. The upper housing 11 is symmetrically rotatably provided with two drive gears 34 located between the first drive plate 311 and the second drive plate 321. The drive gears 34 mesh with the racks 33 in the first drive plate 311 and the second drive plate 321. The top of the upper housing 11 is fixedly provided with a connecting flange 18 around the shaft seat 14. A motor box 19 is connected to the connecting flange 18 by bolts. A motor 4 is installed in the motor box 19, and the power shaft of the motor 4 passes through the motor box 19 and is inserted into the connector 16.

[0024] Through the above technical solution, in use, the power shaft of the motor 4 drives the connector 16 to rotate within the bearing 14, thereby causing the rotating column 15 to rotate. The rotation of the rotating column 15 drives the threaded rod 17 to rotate within the rotating column 15, causing the threaded rod 17 to extend and retract. The extension and retraction of the threaded rod 17 within the rotating column 15 causes the upper clamping plate 31 to move. The movement of the upper clamping plate 31 is achieved through the rack 33 on the first drive plate 311 cooperating with the drive gear 34 and the rack 33 in the second drive plate 321, so that the lower clamping plate 32 and the upper clamping plate 31 move synchronously in opposite directions or in opposite directions, thus completing the process. The clamping or releasing of the paired hoses 2 completes the valve opening and closing operation. Since the motor 4 is located inside the motor box 19 and is plugged into the connector 16, it is easy to install and remove the motor 4 and to maintain the motor 4 without disassembling the valve housing 1. The housing 1 is composed of an upper housing 11 and a lower housing 12. The internal clamping mechanism 3 can be easily maintained by removing the bolts. The upper clamping plate 31 and the lower clamping plate 32 are connected by a drive gear 34 in cooperation with the rack 33 of the first drive plate 311 and the second drive plate 321. The structure is simple and easy to disassemble and maintain.

[0025] Preferably, four symmetrical arc-shaped limiting strips 111 are fixedly provided on both sides of the upper housing 11, and two limiting grooves 312 matching the arc-shaped limiting strips 111 are provided at both ends of the upper clamping plate 31, and the limiting strips 111 and the limiting grooves 312 are slidably connected.

[0026] Through the above technical solution, the arc-shaped limiting strip 11 is slidably connected to the limiting groove 312 in the upper clamping plate 31 to ensure that the upper clamping plate 31 moves stably up and down under the drive of the threaded rod 17, thereby ensuring that the lower clamping plate 32 moves stably up and down.

[0027] Preferably, the upper clamping plate 31 and the lower clamping plate 32 are provided with trapezoidal clamping blocks 35 on the clamping surfaces facing the rubber tube 2, and the top surface of the clamping block 35 abuts against the outer surface of the rubber tube 2.

[0028] Through the above technical solution, the trapezoidal design of the clamping block 35 increases the clamping surface of the tubing 2 and provides support to the side of the tubing 2 during clamping, thus preventing the tubing 2 from breaking due to media impact.

[0029] Preferably, the number of racks 33 in the first drive plate 311 and the second drive plate 321 is the same, and with the cooperation of the first drive plate 311 and the second drive plate 321, the moving paths of the upper clamping plate 31 and the lower clamping plate 32 are equal, which is the radius distance of the hose 2.

[0030] The above technical solution ensures that the upper clamping plate 31 and the lower clamping plate 32 move the same distance, thereby ensuring that the hose 2 is clamped while avoiding damage to the hose 2 due to overpressure.

[0031] Preferably, the top of the connector 16 is provided with a hexagonal connector 161, and the end of the power shaft of the motor 4 matches the hexagonal connector 161.

[0032] Through the above technical solution, the hexagonal shape of the connection port 161 facilitates the insertion with the power shaft of the motor 4, while ensuring the stability of the power output of the motor 4 after insertion.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
