Description

Technical Field

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

[0002] Valves are pipe accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems, with functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion, or overflow pressure relief. Multi-way valves are handle-rotating valves that connect and control multiple pipelines. They are equipped with a valve cover at the top of the valve body, and a valve core connected to the handle is 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 and a radial groove on the bottom of the cylinder.

[0003] The existing multi-way valve has complicated operation steps during use, and it is impossible to quickly switch the pipeline for liquid circulation. At the same time, there are few pipeline interfaces for liquid outflow, so multiple valves need to be used in conjunction. For this reason, we propose a multi-way valve. Utility Model Content

[0007] In a further technical solution, a heating rod is plugged into the lower surface of the valve head, and a temperature sensor is plugged into the lower surface of the valve head and located at the rear end of the heating rod.

[0008] In a further technical solution, a mounting plate is installed on the outer surface of the plane bearing, and the mounting plate is fixedly installed on the reduction motor.

[0009] In a further technical solution, a plurality of threaded holes are provided on one side of the valve head, and quick-insert connectors are threadedly installed on the threaded holes.

[0010] In a further technical solution, a communication hole is provided at the center of the stator, and sixteen water outlet holes are provided on the periphery of the stator.

[0011] In a further technical solution, five water inlet holes are provided at the top end of the valve head, and all the five water inlet holes are communicated with the communication hole.

[0012] In a further technical solution, a strip-shaped hole is provided on one side of the rotor.

[0013] The beneficial effects of the present utility model are as follows:

[0014] Through the designed code disk, photoelectric sensor, rotor, stator and valve head installed at one end of the reduction motor, liquid can flow in from the valve head, then enter the communication hole, and then flow out from one of the water outlet holes through the strip-shaped hole, and finally flow to the outside at the quick connector corresponding to the water outlet hole, playing a very good role in shunting.

[0018] The following further describes the embodiments of the present utility model with reference to the drawings.

[0019] Embodiment:

[0020] As Figure 1As shown in the figure, the multi-way valve includes a reduction motor 1. One end of the reduction motor 1 is equipped with an integrated encoder 2. Four corners at the other end of the reduction motor 1 are fixedly installed with equal-height columns 3. A shaft head 4 is fixedly installed on the output shaft of the reduction motor 1. A code disk 6 is installed on one side of the shaft head 4. An optoelectronic sensor 7 is installed at the top of the code disk 6. A plain bearing 8 is installed on one side of the code disk 6. A wave washer 9 is installed on one side of the plain bearing 8. A rotor 10 is installed on one side of the wave washer 9. A stator 11 is installed on one side of the rotor 10. A valve head 12 is installed on one side of the stator 11. The start of the reduction motor 1 is controlled by the integrated encoder 2. The output shaft of the reduction motor 1 drives the shaft head 4 to rotate. The shaft head 4 drives the code disk 6 and the rotor 10 to rotate. The optoelectronic sensor 7 senses the notch on the code disk 6 and sends a signal to the integrated encoder 2 after sensing. Thus, the integrated encoder 2 controls the start and stop of the reduction motor 1. Liquid flows in through the water inlet hole on the valve head 12, then flows into the interior of the device through the communication hole, and flows into the threaded hole corresponding to one side of the valve head 12 through the strip-shaped hole on the rotor 10, and then flows out to the outside through the quick connector 13, thus completing the transportation of the liquid.

[0021] In another embodiment, as Figure 1 shown, a heating rod 15 is inserted into the lower surface of the valve head 12. A temperature sensor 14 is inserted into the lower surface of the valve head 12 and at the rear end of the heating rod 15. The heating rod 15 can heat up the liquid inside to reach the required temperature.

[0022] In another embodiment, as Figure 1 shown, a mounting plate 5 is installed on the outer surface of the plain bearing 8. The mounting plate 5 is fixedly installed on the reduction motor 1, thus facilitating the installation of the code disk 6 to rotate inside.

[0023] In another embodiment, as Figure 1 shown, a plurality of threaded holes are provided on one side of the valve head 12. Quick connectors 13 are threadedly installed on the threaded holes, facilitating the connection of the external pipeline to the device through the quick connectors 13.

[0024] In another embodiment, as Figure 1 shown, a communication hole is provided at the center of the stator 11. Sixteen water outlet holes are provided on the periphery of the stator 11. The water outlet holes correspond to the external threaded holes, thus facilitating the outflow of the liquid.

[0025] In another embodiment, as Figure 1 shown, five water inlet holes are provided at the top of the valve head 12. All five water inlet holes are communicated with the communication hole, facilitating the inflow of the liquid into the communication hole.

[0026] In another embodiment, as Figure 1As shown in the figure, a strip-shaped hole is provided on one side of the rotor 10. The strip-shaped hole can connect the communication hole and the water outlet hole, facilitating the outflow of liquid.
