Description
Technical Field
The application relates to the technical field of natural gas and oil exploitation, in particular to a driving device of an intelligent flow regulator for a natural gas well.
Background
In order to provide fine control over the production conditions of gas wells, more and more production outlets of gas wells are equipped with flow regulators. The flow regulator mainly comprises a valve body, a valve seat, a valve core and a driving device. The driving device is used for driving the valve core to reciprocate between a closed valve position matched with the valve seat and an open valve position far away from the valve seat.
The driving device usually adopts a motor as a power source. When the valve spool is in the off-position, a large instantaneous force needs to be applied to the valve spool to disengage the valve spool from the off-position due to the fluid pressure within the valve body acting on the valve spool. Once the valve core is separated from the valve closing position, the fluid in the valve body can flow outwards, the fluid pressure borne by the valve core is reduced instantly, and therefore the valve core can be driven to the valve opening position only by applying small force. When the valve core is located at the valve opening position, the valve core is subjected to one-way (direction from the valve closing position to the valve opening position) pressure of fluid in the valve body, and large instantaneous force needs to be applied to the valve core to enable the valve core to be separated from the valve position. When the valve core is separated from the valve position, the valve core is surrounded by the fluid in the valve body, so that the pressure applied to the valve core along the direction from the valve closing position to the valve opening position is balanced with the pressure applied along the direction from the valve opening position to the valve closing position, and the valve core can be driven to the valve closing position only by applying smaller force. Since a large instantaneous force is required to separate the valve body from the closed valve position and the open valve position, a large instantaneous current needs to be applied to the motor. Such transient high current impacts easily cause motor damage.

At this time, the elastic force provided by the second elastic energy storage element can counteract part of the fluid pressure applied on the valve core, so that the instantaneous current applied to the motor is reduced at the moment of taking the valve core out of the valve position. When the motor drives the driving screw to rotate reversely, and the screw sleeve moves to the limit along the direction from the motor to the driving screw (at the moment, the corresponding valve core is positioned at the closed valve position), the first elastic energy storage element is compressed to the limit. At this time, the elastic force provided by the first elastic energy storage element can counteract part of the fluid pressure applied on the valve core, so that the instantaneous current applied to the motor is reduced at the moment of driving the valve core to be separated from the closed valve position. Therefore, the motor is prevented from being impacted by instantaneous large current, and the service life of the motor is prolonged.

Fig. 5 is a schematic diagram of an internal structure of a seal housing 800 in a driving apparatus 010 of an intelligent flow regulator for a natural gas well according to this embodiment.
Referring to fig. 1 to 5, in the present embodiment, a driving device 010 of an intelligent flow regulator for a natural gas well includes a housing 100, a motor 200, a driving screw 300, a threaded sleeve 400, a first elastic energy storage element 510, and a second elastic energy storage element 520.
The motor 200 is fixed to the housing 100. The driving screw 300 is located in the housing 100, and the driving screw 300 is in transmission connection with an output shaft of the motor 200. The screw socket 400 is provided in the housing 100, the screw socket 400 is screw-engaged with the drive screw 300, the screw socket 400 is movably engaged with the housing 100, and the screw socket 400 is configured to move in an axial direction of the drive screw 300 when the drive screw 300 rotates. The first and second elastic energy storage members 510, 520 are both disposed within the housing 100. The first elastic energy storage member 510 is configured to apply an elastic restoring force in the direction from the motor 200 to the drive screw 300 to the nut 400, and the second elastic energy storage member 520 is configured to apply an elastic restoring force in the direction from the motor 200 to the drive screw 300 to the nut 400.
In the driving device 010 of the intelligent flow regulator for the natural gas well provided by the embodiment, the motor 200 drives the driving screw 300 to rotate, and the driving screw 300 drives the threaded sleeve 400 to move along the axis of the threaded sleeve. The screw sleeve 400 is connected with a valve core (not shown) of the intelligent natural gas well flow regulator, so that the valve core is driven to directly move at an open valve position and a closed valve position. When the motor 200 drives the driving screw 300 to rotate forward, and the screw sleeve 400 moves to the limit along the direction from the driving screw 300 to the motor 200 (at this time, the corresponding valve core is located at the open valve position), the second elastic energy storage element 520 is compressed to the limit. The elastic force provided by the second elastic energy storage member 520 can counteract a portion of the fluid pressure applied to the valve element, so that the instantaneous current applied to the motor 200 is reduced at the moment when the valve element is moved away from the valve position. When the motor 200 drives the driving screw 300 to rotate reversely and the screw sleeve 400 moves to the limit along the direction from the motor 200 to the driving screw 300 (at this time, the corresponding valve core is located at the off-valve position), the first elastic energy storage element 510 is compressed to the limit. The elastic force provided by the first elastic energy storage element 510 can counteract a portion of the fluid pressure applied to the valve element, so that the instantaneous current applied to the motor 200 is reduced at the moment of bringing the valve element out of the closed valve position. Thus, the motor 200 is prevented from being impacted by instantaneous large current, and the service life of the motor 200 is prolonged.
Further, in the present embodiment, the nut 400 is provided with a top 410 protruding radially outward. The first elastic energy storage element 510 is located on a side of the abutting portion 410 away from the motor 200, and one end of the first elastic energy storage element 510 is fixed and the other end abuts against the abutting portion 410. The second elastic energy storage element 520 is located at a side of the abutting portion 410 close to the motor 200, and one end of the second elastic energy storage element 520 is fixed and the other end abuts against the abutting portion 410.
Further, in the present embodiment, the first elastic energy storage element 510 and the second elastic energy storage element 520 are both springs, and both the first elastic energy storage element 510 and the second elastic energy storage element 520 are sleeved on the threaded sleeve 400.
Further, in the present embodiment, the screw sleeve 400 is provided with a roller 420, and the roller 420 is in rolling fit with the inner surface of the housing 100.
The screw sleeve 400 is in rolling fit with the inner surface of the housing 100 through the roller 420, so that the friction between the screw sleeve 400 and the roller 420 is reduced, and the operating current of the motor 200 is further reduced.
Further, in the present embodiment, the cross section of the casing 100 is rectangular, and four corners of the cross section of the casing 100 are rounded; four rollers 420 are provided on the screw insert 400. The four rollers 420 are in rolling engagement with the four corners of the cross section of the housing 100. In this manner, radial rotation of the insert 400 is avoided while reducing friction.
Further, in this embodiment, the driving device 010 of the intelligent flow regulator for the natural gas well further includes an inner connection sleeve 600 and an outer connection sleeve 700. The inner connecting sleeve 600 is sleeved on the output shaft of the motor 200, and the outer circumferential surface of the inner connecting sleeve 600 is provided with a plurality of connecting fins 610 protruding radially outward. The outer connecting sleeve 700 is connected to one end of the driving screw 300 close to the motor 200, and a plurality of notches 710 are arranged on the end surface of one end of the outer connecting sleeve 700 close to the motor 200. The inner coupling sleeve 600 is positioned inside the outer coupling sleeve 700 and the coupling fins 610 are inserted into the notches 710.
The motor 200 drives the driving screw 300 to rotate through the cooperation between the inner connection sleeve 600 and the outer connection sleeve 700. The inner connecting sleeve 600 drives the outer connecting sleeve 700 to rotate through the connecting fins 610, and in the starting process of the motor 200, the connecting fins 610 can deform until the connecting fins 610 drive the outer connecting sleeve 700 to rotate, and the working current of the motor 200 is gradually increased in the process. If the motor 200 is hard-connected to the driving screw 300, the operating current of the motor 200 may reach a peak value instantaneously during the starting process of the motor 200, and such current surge is not favorable for the long-term normal operation of the motor 200. In this embodiment, through the flexible cooperation of the inner connecting sleeve 600 and the outer connecting sleeve 700, in the starting process of the motor 200, the working current of the motor 200 is gradually increased, so that the large current impact on the motor 200 is avoided, and the service life of the motor 200 is prolonged.
Further, in the present embodiment, a limiting portion 611 is disposed at an end of the connecting fin 610 away from the inner connecting sleeve 600, and a thickness of the limiting portion 611 is greater than a width of the notch 710; and the radial limiting part 611 is positioned at the outer side of the outer connecting sleeve 700. Thus, the connection fin 610 can be prevented from coming off the notch 710.
Further, in this embodiment, the driving apparatus 010 of the intelligent flow regulator for a natural gas well further includes a sealing case 800, a connecting rod 810, a sealing cover 820, and an elastic sealing mechanism 900. The sealing shell 800 is connected with one end of the shell 100 far away from the motor 200; one end of the connecting rod 810 is connected with the thread insert 400, and the connecting rod 810 penetrates through the sealing shell 800. The other end of the connecting rod 810 is used for connecting with the valve core. The two elastic sealing mechanisms 900 are oppositely arranged in the sealing shell 800 and sleeved on the connecting rod 810. The sealing cover 820 is sleeved on the connecting rod 810 and detachably fixed at one end of the sealing shell 800 far away from the shell 100. A pressurizing spring 830 is further disposed between the two elastic sealing mechanisms 900, and the pressurizing spring 830 is always in a compressed state and applies an axial force to the elastic sealing mechanism 900. The resilient sealing mechanism 900 is configured to radially expand under an axial force.
Specifically, the elastic sealing mechanism 900 includes an inner cylinder 901, a rubber ring 902, and a pressing ring 903. The inner cylinder 901 is made of polytetrafluoroethylene, and the inner cylinder 901 is sleeved on the connecting rod 810 in an axially sliding manner. One end of the inner cylinder 901 protrudes radially outward to form a stopper. The rubber ring 902 is sleeved on the inner cylinder 901. The press ring 903 is also sleeved on the inner cylinder 901. Rubber ring 902 is located between pressure ring 903 and the stop. The press rings 903 of the two elastic sealing mechanisms 900 face each other. The pressing spring 830 acts on the pressing ring 903.
Further, in the present embodiment, the space between the two elastic sealing mechanisms 900 is filled with silicone oil. The silicone oil is in a pressurized state. Specifically, during the assembly process, after one elastic sealing mechanism 900 is installed, silicone oil is filled into the sealing case 800. Then the pressurizing spring 830 and another elastic sealing mechanism 900 are installed. Finally, the sealing cap 820 is installed. The sealing cap 820 is screw-engaged with the sealing housing 800, and the silicon oil is pressurized during the process of tightening the sealing cap 820. The silicone oil in the sealed shell 800 is in a pressurized state, and the fluid pressure in the intelligent flow regulator of the natural gas well can be balanced in the working process, so that the fluid in the intelligent flow regulator of the natural gas well is prevented from leaking.
The above description is only a few examples of the present application and is not intended to limit the present application, and those skilled in the art will appreciate that various modifications and variations can be made in the present application. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
