Description

Fluid valve gear transmission start-stop device

Technical field

The utility model relates to the start-stop device of the construction package of the valve in the fluid pipe-line, particularly valve.

Background technique

In the prior art on gas, the liquid pipeline used mortor operated valve mostly be solenoid valve.The defective that solenoid valve exists mainly is: 1. cause with electrical power consumed big in the unlatching or the down periods of valve because of electromagnet is in "on" position always; 2. volume is bigger; 3. the insufficient sensitivity height is not suitable for being used for large-scale pipeline.

Summary of the invention

The utility model will solve that known mortor operated valve is big with electrical power consumed, volume reaches the high problem of insufficient sensitivity greatly, a kind of fluid valve gear transmission start-stop device is provided, and this device makes valve little in unlatching and down periods electrical power consumed as the opening/closing mechanism of valve, and the volume of valve is little, and is highly sensitive.

For addressing the above problem, its special way of the technical solution adopted in the utility model is to be provided with body frame, be equipped with the turriform gear on the body frame, the turriform gear constitutes by importing gear, connection tooth section, output gear and wearing the whole connection of pawl section from bottom to top successively, be installed with central shaft in the center hole of turriform gear, wear and be with built-in ratchet on the pawl section, built-in ratchet outside is combined with the internal tooth ratchet, be associated with dial axis on the wheel wall of internal tooth ratchet parallel to an axis, the outer transition gear that can rotate relative to this dial axis that is with on the dial axis, transition gear is meshed with described output gear.

Central shaft in the described turriform gear center hole should two ends be fixed and itself is rotatable.

Body frame one side in the utility model can be associated with flange plate.

Input gear in the utility model is associated with motor (being generally micro-machine in the enforcement) the input power of gear by rotating shaft, when the input gear rotates together with output gear and built-in ratchet corotation.If clockwise rotating, built-in ratchet is slipping state, cooperate this moment the internal tooth ratchet that is coated at built-in ratchet not rotate because of skidding, the transition gear engagement output gear original place (the spindle heart is unshift) that is placed in internal tooth dial axis that ratchet joins rotates counterclockwise, and be the opening of valves state this moment; Oppositely, built-in ratchet rotates counterclockwise, and drive the internal tooth ratchet rotate counterclockwise this moment, can change around the output gear torus clockwise when being placed in the clockwise rotation of the transition gear engagement output gear of dial axis, and when ring changes an angle, be the valve closed condition.In the enforcement, this kind closed and is quick closedown.In the valve down periods, electricity consumption is zero-power (the motor short time stops after rotating), and the unlatching of valve is the short time electricity consumption also.The positive and negative rotation of the utility model motor can realize the unlatching of valve or closes, and the equal short time of motor promptly stops after rotating in the process.

The utility model is owing to be provided with this turriform gear of turriform gear by the input gear, connection tooth section, output gear and wear the whole connection of pawl section and constitute, wear and be with built-in ratchet on the pawl section, built-in ratchet fit on has the internal tooth ratchet, and it is taken turns and is associated with dial axis on the wall, be with transition gear on the dial axis and be engaged in output gear, when built-in ratchet clockwise or when rotating counterclockwise, realization transition gear original place is rotated or is changeed around the output gear torus, so utilize this kinematic relation, can realize the unlatching of valve or close, and realization power saving effect, try out and show that on the family expenses gas pipe line, four No.5 cells can be with more than 3 years.Device of the present utility model can be made small volume in the enforcement, is fit to small volume valve adapted.The valve that cooperates with electromechanical device of the present utility model, relative solenoid valve, sensitivity is higher, and suitable large-scale pipeline valve adapted.Device of the present utility model also is fit to use on the fluid meter.
