Abstract

The utility model relates to a gear transmission opening-closing device for a fluid valve, which can be matched with the valve and can lead the operation of the valve to have the advantages of electricity saving, small volume and high sensitivity. The utility model is provided with a main body frame (5) which is provided with a drive gear (1), a gear shaft which is penetrated and arranged on a shaft hole of the main body frame is fixed on the center position of the drive gear, and a sun gear (6) and a built-in ratchet pawl (8) are connected to the gear shaft in the mode of axial center in common. An inner gear ratchet wheel (9) is matched and arranged out of the built-in ratchet pawl, and a core shaft (91) is parallelly connected with the wheel wall of the inner gear ratchet wheel onside in axial direction. A leaning gear (7) which can rotate relatively to the core shaft is sheathed on the outside of the core shaft and is engaged with the sun gear (6). The utility model can be used as an opening-closing device to be matched and suitable for a mechanical electric valve.

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 main frame, main frame is provided with driving gear, the driving gear center is fixed with the axis hole that gear shaft is placed through main frame, coaxial heart is associated with central gear and built-in ratchet on the gear shaft, built-in ratchet outside is equipped with the internal tooth ratchet, be associated with mandrel on the wheel wall of internal tooth ratchet parallel to an axis, be with the gear that leans on that this mandrel relatively rotates outward on the mandrel, lean on gear to be meshed with described central gear.

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

Driving gear in the utility model is imported power by the motor (being generally micro-machine in the enforcement) that rotating shaft is associated with gear, when driving gear rotates, and central gear and built-in ratchet shaft coupling corotation.If establishing built-in ratchet clockwise rotates and is slipping state, cooperate this moment the internal tooth ratchet that is coated at built-in ratchet not rotate, be placed in rotating counterclockwise by gear engagement central gear original place (the spindle heart is unshift) of internal tooth ratchet wheel mandrel that wall joins, be the opening of valves state this moment; Oppositely, built-in ratchet rotates counterclockwise, and drive the internal tooth ratchet rotate counterclockwise this moment, be placed in mandrel by the clockwise rotation of gear engagement central gear the time can change around the centre tooth torus clockwise, 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 associated with central gear and built-in ratchet owing to being provided with on its gear shaft of driving gear, built-in ratchet fit on has the internal tooth ratchet, and it is taken turns and is associated with mandrel on the wall, be with by gear engagement on the mandrel in central gear, when built-in ratchet clockwise or when rotating counterclockwise, realize changeing by the rotation of gear original place or around the centre tooth torus, so utilize this kinematic relation, can realize the unlatching of valve or close, and realization power saving effect, on probation showing, 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.
