Description
Technical Field
The utility model relates to an motorised valve technical field especially relates to a motorised valve with manual control function.
Background
The electric valve simply controls the valve by using an electric actuator, thereby realizing the opening and closing of the valve. The electric actuator can be divided into an upper part and a lower part, wherein the upper part is the electric actuator, and the lower part is the valve. At present, the existing small-sized electric valve rarely has a manual function. Although some electric valves have a manual control function, a handle of the manual control generally rotates along with a motor and a transmission shaft. Such rotation can cause wear to the workpiece and power loss.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides an motorised valve with manual control function
In order to realize the purpose of the utility model, the technical proposal of the utility model is that: an electric valve with a manual control function comprises an electric actuator, wherein the electric actuator comprises a main transmission shaft, the bottom of the main transmission shaft is connected with a valve rod on a valve body of an electromagnetic valve, the main transmission shaft is connected with a motor through a gear set, one gear in the gear set is a manual connection gear, one side of the manual connection gear is provided with a manual control gear, and a manual control shaft capable of driving the manual control gear to move up and down is fixed in the center of the manual control gear; and when manual control is performed, the manual control shaft is lowered, the manual control gear is meshed with the manual connecting gear, and the valve is controlled to be opened and closed by rotating the manual control shaft.
Furthermore, a sleeve with a spring is sleeved outside the manual control shaft, when manual control is not performed, the spring lifts the manual control shaft, and the manual control gear is suspended above the manual connecting gear.
Furthermore, the gear set comprises a first transmission gear, a second transmission gear, a third transmission gear, a fourth transmission gear and a fifth transmission gear which are sequentially connected with the motor, and the fifth transmission gear is connected with the main transmission shaft; the third transmission gear or the fourth transmission gear is a manual connecting gear.
Furthermore, the top of the manual control shaft is provided with a projection or a groove for applying a rotating acting force.
Furthermore, a sealing washer is sleeved outside the manual control shaft.
The utility model has the advantages that:
1. when manual control is not needed, the manual gear can be separated, and the original performance of the electric valve is not influenced.
2. The valve can be opened and closed by a small force by amplifying the torque by using the gears in the transmission gear set. Through calculation, only 0.1Nm is needed.
3. The gear case and the electromotive part can be effectively sealed by the spring and the gasket.

FIG. 2 is a manual control shaft;
FIG. 3 is a top view of the electric actuator;
fig. 4 shows a state in which the manual control gear is suspended above the manual connection gear.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
As shown in fig. 1-4, in order to achieve the above object of the present invention, the technical solution of the present invention is: an electric valve with a manual control function comprises an electric actuator, wherein the electric actuator comprises a motor 1, the motor 1 is sequentially connected with a first transmission gear 2, a second transmission gear 3, a third transmission gear 4, a fourth transmission gear 5 and a fifth transmission gear 6, and the fifth transmission gear 6 is connected with a main transmission shaft 7; wherein the third transmission gear 4 acts as a manual coupling gear. A manual control gear 8 is arranged beside the third transmission gear 4, and a manual control shaft 9 which can drive the manual control gear to move up and down is fixed at the center of the manual control gear 8; the manual control shaft 9 is externally sleeved with a sleeve 10 with a spring, and the top of the manual control shaft is provided with a bulge 11 (which can also be a straight groove and can be rotated by a screwdriver) for applying a rotating acting force. The manual control shaft is also sleeved with a sealing gasket (positioned in the sleeve and not shown) for dust prevention.
When the manual control is not carried out, the spring on the sleeve lifts the manual control shaft, and the manual control gear is suspended above the manual connecting gear. If manual control is needed, the manual control shaft is pressed down to be lowered, the manual control gear is meshed with the manual connecting gear, and the valve can be controlled to be opened and closed by rotating the manual control shaft.
The described embodiments are only some, but not all embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
