[0002] Nowadays, winter in the north is very cold, and heating is a necessity for people's lives. After the warm water is boiled in the boiler, it is transported to different users through pipes for heating. However, in the process of transporting warm water through pipes, due to heat loss, flow channel design, pressure difference and other reasons, the warm current is often unevenly distributed, which leads to some users' indoors being too warm, while some users are not warm enough; low-level users will be warmer and high-level users will be colder; the central unit of the house will be warmer, while the peripheral users will be colder. At the same time, the working and installation environment of the regulating valve is relatively compact, and it is in an unmanned machine room for a long time. In view of this problem, the traditional regulating valve cannot meet the needs of users when the valve is fully open.

The rotation speed of the impeller 31 is controlled by adjusting the speed of the motor 1 to pressurize the fluid passing through the regulating valve.

[0030] A support rod 12 is provided directly below the second driven gear 22, and the support rod 12 is sequentially sleeved with a movable disk 26 and a limit block 13 from top to bottom. The movable disk 26 can move up and down on the support rod 12, and the limit block 13 is fixedly connected to the support rod 12. A spring 14 is connected to the upper end of the limit block 13, and the other end of the spring 14 is connected to the movable disk 26. A shift fork 9 is connected to the side of the movable disk 26. A lever bracket 11 is provided on the bottom plate 8, and the middle part of the shift fork 9 is mounted on the lever bracket 11. A linkage gear 20 is sleeved on the support rod 12 above the movable disk 26, and the linkage gear 20 can move up and down on the support rod 12. Friction rubber sheets 21 are respectively provided on the upper side of the linkage gear 20 and the lower side of the second driven gear 22. A permanent magnet is provided at the end of the shift fork 9, and an electromagnetic travel switch 10 using remote wireless control is provided below the end of the shift fork 9. The electromagnetic travel switch 10 consists of a coil, a magnetic core and a shell, and uses the principle of electromagnetism to control the movement of the shift fork 9.

[0031] The upper end of the lever bracket 11 has an arc, which serves as a fulcrum for prying the linkage gear 20 upward, thereby prying the linkage gear 20 upward to perform friction transmission with the second driven gear 22. The end of the fork 9 moves downward under the attraction of the magnetic force, and the movable plate 26 moves upward to support the linkage gear 20 to move upward, so that the two friction rubber sheets 21 are in close contact, and the linkage gear 20 can rotate under the drive of the second driven gear 22. One side of the linkage gear 20 is provided with a valve core shaft gear 18 meshing with it, and the center of the valve core shaft gear 18 is provided with a keyway, and the valve core shaft 19 is clamped in the keyway, so that the valve core shaft 19 can be driven by the valve core shaft gear 18 to make a circular motion while also moving up and down. A valve core 15 is provided at the lower end of the valve core shaft 19, and an external thread is provided on the outer side of the valve core shaft 19. A threaded rotating sleeve 17 with an internal thread matching the external thread is fixedly sleeved on the valve core shaft 19. The valve core shaft gear 18 drives the valve core shaft 19 to rotate. Due to the existence of the threaded rotating sleeve 17, the circular rotation of the valve core shaft 19 is simultaneously converted into linear motion. The valve core 15 realizes contact and separation with the inner wall of the cavity by vertically moving up and down, thereby achieving the function of controlling the switch of the regulating valve.

[0032] Working and use process:

[0033] The specific working process of an electrically controlled impeller boost regulating valve includes two power transmission routes. The first route is to control the rotation of the impeller 31; the second route is to control the up and down opening and closing linear motion of the valve core 15. First, the power is transmitted from the motor 1 through the motor shaft 32 to the driving gear 4, and the power is transmitted to the first driven gear 24 through the gear transmission. The first driven gear 24 drives the second driven gear 22 to rotate through the transmission shaft 25. The second driven gear 22 is meshed with the impeller shaft gear 2. The impeller shaft gear 2 drives the impeller 31 to rotate to realize the water flow pressurization of the whole system. In order to prevent the impeller 31 from being disturbed, a limit pin 33 is provided below it. Secondly, the power is transmitted from the motor 1 to the driving gear 4 through the motor shaft. When a signal to open or close the valve core 15 is received, the electromagnetic travel switch 10 obtains magnetic force due to electromagnetism to attract the ends of the shift fork 9 downward. The shift fork 9 overcomes the action of the spring 14 to pry the linkage gear 20 upward and make the two friction rubber sheets 21 contact each other to realize the friction transmission between the second driven gear 22 and the linkage gear 20, drive the linkage gear 20 to move, and transmit the power to the valve core shaft gear 18. Driven by the valve core shaft gear 18, the valve core shaft 19 rotates, and the internal thread on the threaded rotating sleeve 17 cooperates with the external thread on the valve core shaft 19 to convert the circular motion into a linear reciprocating motion, so that the valve core 15 can realize the opening and closing function.

[0034] The two power transmission routes can be carried out simultaneously or separately. For example, when the valve core 15 is opened, there is no need to control the movement of the valve core. At this time, the electromagnetic travel switch 10 is powered off, and the valve core shaft 19 stops rotating.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
