[0037] The following describes this application in detail with reference to the embodiments, but this application is not limited to these embodiments.

[0038] According to Figures 1-4 A remote pressure regulating device for a gas field regulator as shown, includes:

[0039] Housing 1;

[0040] Control module;

[0041] The drive motor 12 and the positioning sleeve 8 are arranged on the outer sides of the opposite sides of the housing 1, and the drive motor 12 is installed on the housing 1;

[0042] And a pressure regulating transmission mechanism, a speed regulating mechanism, and a pressure regulating protection mechanism arranged in the housing 1.

[0043] Among them, the input end of the pressure regulating transmission mechanism is connected to the drive motor 12, and the output end of the pressure regulating transmission mechanism is connected to the positioning sleeve 8; the pressure regulating transmission mechanism includes a driving wheel 2 and a driven wheel 6 arranged in sequence from left to right along the transverse direction of the housing 1;

[0044] The speed regulation mechanism is located between the driving wheel 2 and the driven wheel 6. The speed regulation mechanism includes a horizontally arranged speed change part and a vertically arranged second speed change part. The first speed change part and the second speed change part share a part. The speed change part includes a driving wheel 3 and a speed change wheel 3 arranged in sequence from back to front along the longitudinal direction of the housing 1. The second speed change part includes a speed change wheel 3 and a positioning wheel 5 arranged in sequence from top to bottom along the vertical direction of the housing 1. The speed change wheel 3 is the shared part of the first speed change part and the second speed change part. The driving wheel 3 is located between the driving wheel 2 and the driven wheel 6 and is horizontally engaged with the driving wheel 2 and the driven wheel 6 respectively. The speed change wheel 3 is located on the side of the driving wheel 3 facing away from the driving motor 12. The speed change wheel 3 is arranged at an interval from the driving wheel 3 and is coaxially linked with the driving wheel 3. The positioning wheel 5 is located below the speed change wheel 3. The wheel surface of the positioning wheel 5 and the speed change wheel 3 are in the same plane. The positioning wheel 5 is engaged with the speed change wheel 3.

[0045] The voltage regulation and protection mechanism is located below the positioning wheel 5. The voltage regulation and protection mechanism includes a rack 9 horizontally arranged along the transverse direction of the housing 1 and micro switches 11 located at both ends of the rack 9.

[0046] The centers of the positioning wheel 5 and the speed change wheel 3 are on the same straight line. The rack 9 is engaged with the positioning wheel 5.

[0047] In this application:

[0048] The connection between the driving wheel 2 and the housing 1 is realized through a first rotating shaft. The connection between the driving wheel 3 and the housing 1 is realized through a second rotating shaft. The connection between the driven wheel 6 and the housing 1 is realized through a third rotating shaft. The connection between the positioning wheel and the housing 1 is realized through a fourth rotating shaft. The first rotating shaft, the second rotating shaft, the third rotating shaft and the fourth rotating shaft are arranged in parallel. The first rotating shaft penetrates the driving wheel 2, one end is rotatably connected to one side of the housing 1, and the other end passes through the other side of the housing 1 and is connected to the output end of the driving motor 12. The second rotating shaft penetrates the driving wheel 3. One end of the second rotating shaft is rotatably connected to one side of the housing 1. The other end of the second rotating shaft passes through the speed change wheel 3 of the speed regulation mechanism and is connected to the other side of the housing 1. One end of the third rotating shaft is connected to one side of the housing 1. The other end of the third rotating shaft sequentially passes through the driven wheel 6 and the other side of the housing 1 and is connected to one end of the positioning sleeve 8. The other end of the positioning sleeve 8 is sleeved outside the pressure regulating bolt 7 of the voltage regulator. The fourth rotating shaft penetrates the positioning wheel, and both ends of the fourth rotating shaft are respectively connected to the opposite sides of the housing 1.

[0049] It should be noted that the housing 1 is fixed outside the gas pressure regulator. The inner diameter of the positioning sleeve 8 is matched with the gear of the pressure regulating bolt 7 of the pressure regulator. Since one end of the positioning sleeve 8 is connected to one end of the driven wheel 6 and the other end is sleeved outside the pressure regulating bolt 7 of the pressure regulator, during pressure regulation, the driving motor 12 drives the driving wheel 2 to rotate. The driving wheel 2 transmits the motion to the driven wheel 6 through the transmission wheel 3. The driven wheel 6 rotates, driving the positioning sleeve 8 sleeved outside the pressure regulating bolt 7 to rotate, rotating the pressure regulating bolt 7, thereby realizing the adjustment of the pressure of the pressure regulator.

[0050] To prevent the regulated pressure from exceeding the safe range during the pressure regulation process, the present application is provided with a pressure regulation protection mechanism. Specifically, during the pressure regulation process, the motion of the driving wheel 2 is converted into the horizontal motion of the rack 9 along the transverse direction of the housing 1 through the speed regulation component. When the rack 9 slides to the left top end, the rack 9 touches the micro switch 11 on the left and the circuit is disconnected, and the driving motor 12 stops running; when the rack 9 slides to the right top end and touches the micro switch 11 on the right, the circuit is disconnected and the driving motor 12 stops running, realizing the protection function during the pressure regulation process.

[0051] In an embodiment of the present application, the power of the driving motor 12 is relatively small, only 14W, and a fuse tube with a current of 0.5A is selected in the circuit system to provide secondary protection for the circuit system.

[0052] To make the structure of the device lightweight, in an embodiment of the present application, the housing 1 is made of 6061 aluminum alloy or 7075 aluminum alloy, which has the advantages of high strength, corrosion resistance, high toughness and good workability.

[0053] To reduce the size of the device without affecting the realization of the functions of each internal mechanism, the present application realizes this by reasonably setting the module ratios of the gears and the rack 9 in the pressure regulation transmission mechanism, the speed regulation mechanism and the protection mechanism, that is, the module of the gears of the driving wheel 2, the transmission wheel 3 and the driven wheel, and the module of the positioning wheel 5 and the rack 9 are determined according to the space of the housing 1. In an embodiment of the present application: the module ratios of the gears of the driving wheel 2, the transmission wheel 3 and the driven wheel 6 are all 1:1; the module of the positioning wheel 5 and the rack 9 is 1:1. To further reduce the space, the module of the positioning wheel 5 and the rack 9 can also be set to 0.5.

[0054] To increase the movement accuracy of the rack 9, in the present application, this is realized by setting a speed change adjustment mechanism. Specifically, the transmission ratios of the driving wheel 2, the transmission wheel 3 and the driven wheel are 2:4:2 in sequence. The gear transmission ratio of the transmission wheel 3 and the positioning wheel 5 is 4:1.

[0055] In order to increase the stability of the rack 9 during movement, in this application, a chute 10 is provided at the top of the bottom plate of the housing 1, and a slider is provided at the bottom of the rack 9. The chute 10 is located directly below the positioning wheel 5, and the center of the chute 10 and the center of the positioning wheel are on the same straight line. Two microswitches 11 are respectively installed at the two ends of the chute 10, and the slider is fixed at the center of the bottom of the rack 9 and is slidably connected in the chute 10.

[0056] In this application, the control module is located outside the housing 1 and includes a distribution box, a controller, a start switch, an emergency stop switch, a forward rotation start switch, a reverse rotation start switch, a forward rotation stop switch, and a reverse rotation stop switch;

[0057] The controller is connected to the distribution box;

[0058] The motor start switch, the emergency stop switch, the forward rotation start switch, the reverse rotation start switch, the forward rotation stop switch, the reverse rotation stop switch, and the two microswitches 11 are respectively connected to the controller;

[0059] In order to facilitate observing the adjustment process, a motor forward rotation indicator light and a motor reverse rotation indicator light are also provided on the control module, and the motor forward rotation indicator light and the motor reverse rotation indicator light are respectively connected to the controller.

[0060] In this application, the drive motor 12 is a synchronous permanent magnet low-speed motor (1 revolution / min) and can achieve forward and reverse rotation.

[0061] In order to prevent this adjustment device from being fixed outside the voltage regulator and affecting the voltage regulator, in this application, in order to make this device lighter, the housing in this application is a lightweight housing made of aviation aluminum alloy; the overall size of the housing is 210*100*40mm.

[0062] Since this device is applied to a gas field, the housing of this device and all components designed in the pressure regulating transmission mechanism and the pressure regulating protection mechanism (including the drive motor, the positioning sleeve, and the microswitch) are all explosion-proof treated.

[0063] The above are only several embodiments of this application and do not impose any form of limitation on this application. Although this application is disclosed above with preferred embodiments, it is not intended to limit this application. Any person skilled in this profession, without departing from the technical solution of this application, making some changes or modifications using the technical content disclosed above is equivalent to an equivalent implementation case and all fall within the scope of the technical solution.
