Abstract
The utility model discloses a slidingtype moment of torsion transfer device, including sleeve and dabber, the muffjoint is on manual choke valve valve rod, and dabber one end is connected and be used for transmitting the electric actuator moment of torsion in the electric actuator rotor, and the other end lies in the sleeve and agrees with with the sleeve and pass through the sleeve with the moment of torsion and transmit for the valve rod, and the other end sets up to the polygon, and the correspondence of sleeve inner chamber sets up to the polygon. The utility model provides an electric actuator when connecting with manual choke valve, manual choke valve valve rod when rotatory simultaneously axial motion lead to the problem that the two can't be compatible.
Description
Technical field
The utility model relates to a kind of torque transmitter, particularly a kind of sliding type torque transmitter, be mainly applicable to the electric actuator of valve and partially manual throttle valve with the use of in.
Background technique
Along with deepening continuously of China's oil natural gas resource exploration and development, Oil testing technology obtains increasing attention.Ground test measurment technique there has also been significant progress, and more telecontrol, centralized control technique start to occur.For the control of valve, electric actuator obtains increasing application.But electric actuator and partially manual throttle valve with the use of time, there is problem.Electric actuator is connected on the valve rod of manual throttle valve.Electric actuator provides moment of torsion, just rotates and without axial motion during its working rotor, and the valve rod of manual throttle valve also can axial motion while rotation, and this causes the two to support the use.
Summary of the invention
The purpose of this utility model is the problems referred to above overcoming prior art existence, provides a kind of sliding type torque transmitter.The utility model solves electric actuator when being connected with manual throttle valve, problem that cannot be compatible both the axial motion simultaneously when rotated of manual throttle valve valve rod causes.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of sliding type torque transmitter, it is characterized in that: comprise sleeve and mandrel, described sleeve connection is on manual throttle valve valve rod, mandrel one end is connected in electric actuator rotor for transmitting electric actuator torque, the other end is positioned at sleeve and agrees with sleeve and moment of torsion is passed to valve rod by sleeve, and the other end is set to polygonal, barrel bore correspondence is set to polygonal.
When electric actuator band ovable valve stem rotates, the Axially moving belt moving sleeve of described valve rod slides outward at mandrel.
Employing the utility model has the advantage of:
1, the utility model solves electric actuator when being connected with manual throttle valve, problem that cannot be compatible both the axial motion simultaneously when rotated of manual throttle valve valve rod causes, during work, electric actuator band ovable valve stem rotates, the Axially moving belt moving sleeve of valve rod slides outward at mandrel, and the axial motion of valve rod can not be delivered on electric actuator rotor.
2, after adopting the utility model, during slip, torque transmitter is specially for solving electric actuator when being connected with manual throttle valve, due to the simultaneously axial motion when rotated of manual throttle valve valve rod causes the two cannot compatible problem and designing, structure is simple, reliability is high, with low cost, can be applicable to the various moment of torsion transmission with axial motion, there is wide application prospect.

Fig. 2 is the utility model plan structure schematic diagram
Be labeled as in figure: 1, sleeve, 2, mandrel.
Embodiment
The utility model is used for the connection of electric actuator and manual throttle valve.Below structural principle of the present utility model is described.
A kind of sliding type torque transmitter, comprise sleeve 1 and mandrel 2, described sleeve 1 is connected on manual throttle valve valve rod, mandrel 2 one end is connected in electric actuator rotor for transmitting electric actuator torque, the other end is positioned at sleeve 1 and agrees with sleeve 1 and moment of torsion is passed to valve rod by sleeve, and the other end is set to polygonal, sleeve 1 inner chamber correspondence is set to polygonal.
When electric actuator band ovable valve stem rotates, the Axially moving belt moving sleeve of described valve rod slides outward at mandrel.
In the utility model, combined by sleeve and mandrel, transmitting torque and don't transmission axial force.Described sliding type torque transmitter mandrel is polygonal, can effective transmitting torque.
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, sliding type torque transmitter mainly comprises following components: sleeve 1, mandrel 2.Sleeve 1 is connected on manual throttle valve valve rod, and mandrel 2 one end is arranged in electric actuator rotor, and for transmitting electric actuator torque, the other end is polygonal, in sleeve 1, and agrees with sleeve 1, moment of torsion is passed to valve rod by sleeve.During work, electric actuator band ovable valve stem rotates, and the Axially moving belt moving sleeve 1 of valve rod, in the outer slip of mandrel 2, makes the axial motion of valve rod can not be delivered on electric actuator rotor.
Claims (2)
