Description

Technical Field

[0001] The utility model relates to the technical field of multi-way valves, in particular to a high-load multi-way valve. Background Art

[0002] A multi-way valve is a handle rotary valve that connects and controls multiple pipelines. It consists of a valve cover on the upper end of the valve body, and a valve core connected to the handle installed in the valve body. The upper end of the valve body is an open cylinder, and the lower end has multiple parallel pipe joints that are connected to the two holes on the bottom of the cylinder and a radial groove.

[0003] During use, the existing multi-way valve usually uses the motor output shaft to fix directly to the sleeve. When the sleeve bears a large force or runs for a long time, the motor is easily damaged due to the load. For this reason, we propose a high-load multi-way valve. Utility Model Content

[0004] In view of the above problems, the utility model provides a high-load-bearing multi-way valve with good load-bearing capacity.

[0005] The technical solution of the utility model is:

[0006] A high-load multi-way valve comprises a motor, a motor mounting plate is fixedly mounted on one end of the motor, an eccentric wheel is fixedly mounted on the output shaft of the motor, a bearing is mounted on the outer surface of the eccentric wheel, a bushing is mounted on the outer surface of the bearing, a ball fixing seat is mounted on the outer surface of the bushing, a plurality of through holes are opened on the outer side of the ball fixing seat, balls are mounted at the through holes, a cycloid inner rim is mounted on the outer surface of the ball fixing seat, an output shaft is fixedly mounted on one side of the cycloid inner rim, a mounting bearing is mounted on the outer surface of the output shaft, and a sleeve is fixedly mounted on one end of the output shaft.

[0007] In a further technical solution, a box is installed on the outer surface of the cycloid inner rim, a fixing plate is installed on one side of the box, and a fixing seat is installed on one side of the fixing plate.

[0008] In a further technical solution, a cover is installed on the outside of the motor, a control board is fixedly installed on one end of the motor, a rear cover is also installed on one side of the control board, the rear cover is installed at one end of the cover, and the fixing seat is installed at the other end of the cover.

[0009] In a further technical solution, a position code disk is installed on the outer surface of the sleeve, a photoelectric sensor is installed on the top of the position code disk, a pin is installed on one end of the sleeve, a connecting bearing is installed on one end of the pin, a gasket is installed on one end of the connecting bearing, a rotating shaft is installed on one end of the gasket, a rotating disk is installed on one end of the rotating shaft, a valve seat is fixedly installed on one side of the fixed seat, a valve cover is fixedly installed on one side of the valve seat, a valve ring is installed on one side of the valve cover, and a fixed disk is installed on one side of the rotating disk.

[0010] The beneficial effects of the utility model are:

[0011] The eccentric wheel drives the bushing to rotate, and the bushing squeezes the ball on the fixed seat, so that the ball can drive the cycloid inner wheel ring to rotate, thereby obtaining a higher load-bearing capacity, allowing the sleeve to carry heavier objects or operate for a long time, improving the application environment of the device and extending its service life.

[0015] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0016] Example:

[0017] like Figure 1 As shown, a high-load multi-way valve includes a motor 2, a motor mounting plate 5 is fixedly mounted on one end of the motor 2, an eccentric wheel 6 is fixedly mounted on the output shaft of the motor 2, a bearing 7 is mounted on the outer surface of the eccentric wheel 6, a bushing 8 is mounted on the outer surface of the bearing 7, a ball fixing seat 9 is mounted on the outer surface of the bushing 8, a plurality of through holes are opened on the outer side of the ball fixing seat 9, balls 10 are mounted at the through holes, a cycloid inner wheel rim 11 is mounted on the outer surface of the ball fixing seat 9, an output shaft 13 is fixedly mounted on one side of the cycloid inner wheel rim 11, a mounting bearing 12 is mounted on the outer surface of the output shaft 13, and a sleeve 16 is fixedly mounted on one end of the output shaft 13.

[0018] The working principle of the above technical solution is as follows:

[0019] By starting the motor 2, the output shaft of the motor 2 drives the eccentric wheel 6 to rotate. Since the eccentric wheel 6 adopts an eccentric design, the eccentric wheel 6 drives the bushing 8 to swing through the bearing 7. The bushing 8 drives the ball 10 on the ball fixing seat 9 to move, thereby driving the cycloid inner wheel rim 11 to rotate. The cycloid inner wheel rim 11 drives the sleeve 16 to rotate through the output shaft 13. This transmission method can make the sleeve 16 have a larger load-bearing capacity.

[0020] In another embodiment, if Figure 1 As shown, a box body 14 is installed on the outer surface of the cycloid inner rim 11, a fixing plate is installed on one side of the box body 14, and a fixing seat 18 is installed on one side of the fixing plate, so as to facilitate the installation of various components.

[0021] In another embodiment, if Figure 1 As shown, a cover 1 is installed on the outside of the motor 2, a control board 3 is fixedly installed on one end of the motor 2, a rear cover 4 is also installed on one side of the control board 3, the rear cover 4 is installed at one end of the cover 1, and a fixing seat 18 is installed at the other end of the cover 1, so that each component is protected by the cover 1.

[0022] In another embodiment, if Figure 1 As shown, a position code disk 15 is installed on the outer surface of the sleeve 16, a photoelectric sensor 17 is installed on the top of the position code disk 15, a pin 20 is installed at one end of the sleeve 16, a connecting bearing 21 is installed at one end of the pin 20, a gasket 22 is installed at one end of the connecting bearing 21, a rotating shaft 23 is installed at one end of the gasket 22, a rotating disk 24 is installed at one end of the rotating shaft 23, a valve seat 19 is fixedly installed on one side of the fixed seat 18, a valve cover 26 is fixedly installed on one side of the valve seat 19, a valve ring 27 is installed on one side of the valve cover 26, and a fixed disk 25 is installed on one side of the rotating disk 24.

[0023] The pin 20 is driven to rotate by the shaft sleeve 16, and the pin 20 drives the rotating shaft 23 and the rotating disk 24 to rotate, so that the transverse groove on the rotating disk 24 is aligned with any hole on the periphery of the fixed disk 25, and the hole in the middle is aligned, so that the inflowing liquid can be discharged through different pipes.

[0024] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
