[0070] Specifically, the mounting seat 14 is Z-shaped as a whole, and there is an arc transition between the first plate segment 141 and the second plate segment 142 to avoid stress concentration in the structure; an inner chamfer is provided at the bottom of the first plate segment 141 for matching the first clamping plate 12 and the second clamping plate 13 for snap-in installation.

[0071] In this embodiment, the second plate segment 142 is provided with a second through hole 144, and the transmission shaft 331 of the driven gear 33 passes through the second through hole 144 and is connected to the transmission member 20; the transmission shaft 331 is a stepped shaft, and the stepped shaft includes a first shaft segment 332 and a second shaft segment 333, and a first stop step is formed between the first shaft segment 332 and the second shaft segment 333, and a part of the shaft segment of the first shaft segment 332 is inserted into the transmission member 20; the transmission mechanism 30 also includes a bearing 35, which is sleeved on the first shaft segment 332 and located in the second through hole 144, and the inner ring of the bearing 35 is located between the transmission member 20 and the first stop step.

[0072] In this embodiment, the second through hole 144 is a stepped hole, which includes a first hole section 145 and a second hole section 146, and a second stop step is formed between the first hole section 145 and the second hole section 146; the bearing 35 is located in the second hole section 146; the transmission mechanism 30 also includes: an end cover 36 connected to the mounting seat 14, the limit end of the end cover 36 is located in the second hole section 146, and the outer ring of the bearing 35 is located between the limit end and the second stop step. Such a setting limits the movement of the driven gear 33 in the axial direction.

[0073] In this embodiment, the driven gear 33 is provided with a first fastening hole penetrating the transmission shaft 331; the transmission member 20 is provided with a second fastening hole 24; the transmission mechanism 30 further includes: a first fastener 37, the first fastener 37 passes through the first fastening hole and is inserted into the second fastening hole, and the first fastener 37 is locked and connected to both the driven gear 33 and the transmission member 20. Such a setting realizes the fixed connection between the driven gear 33 and the transmission member 20, so that the driven gear 33 drives the transmission member 20 to rotate.

[0074] Specifically, the first fastener 37 is a screw.

[0075] In specific implementation, the transmission mechanism 30 adopts gear transmission, and the anti-loosening design involves axial and radial restrictions. The radial installation constraint is performed through the first through hole 143 and the second through hole 144 of the mounting seat 14, that is, the mounting hole position design of the mounting seat 14 guarantees it; the disturbance end of the axial accuracy is mainly in the driven gear 33, and the driving gear 32 is directly mounted on the output shaft 311 of the driving member 31, installed through a keyway and with screws on the side end, and the driving gear 32 rotates with the output shaft 311; and the driven gear 33 is the passive end and needs to be fixed by a positioning structure. Its axial fixing method is the first fastener 37. The driven gear 33 is provided with a transmission shaft 331, and the transmission shaft 331 penetrates into the upper end of the transmission member 20. By screwing in the first fastener 37, the distance between the driven gear 33 and the transmission member 20 is adjusted to limit the axial movement of the driven gear 33.

[0076] In specific implementation, the driven gear 33 needs to rotate, and its installation is to ensure the rotation of the inner ring of the bearing 35 and the fixation of the outer ring of the bearing 35 by inserting the bearing 35. The specific fixing design is as follows: Fig.14 As shown, the axial limitation needs to constrain the shaking amount of the inner and outer rings of the bearing 35, so that the driven gear 33 has good axial limitation. The outer ring of the bearing 35 is set as the fixed end, and points a and c are static ends. Point a is the limit end of the end cover 36 to press the upper end surface of the outer ring of the bearing 35, and point c is the second stop step to support the lower end of the outer ring of the bearing 35. By tightening the screws of the end cover 36, the outer ring of the bearing 35 is completely fixed. In particular, a designed gap e is provided below the end cover and between the mounting seat 14 to ensure that there is a pre-load margin after points a and c contact the outer ring of the bearing 35, and always keep the tight contact of point a of the end cover 36; the inner ring of the bearing 35 is the rotating part, and points b and d are the movable ends. Point b is the first stop step to press down the upper surface of the inner ring of the bearing 35, and point d is the upper end of the transmission member 20 to support the inner ring of the bearing 35, and it is tightened by the first fastener 37 to achieve the axial fixation of the inner ring of the bearing 35.

[0077] In specific implementation, the gear transmission end needs to avoid the long cantilever form, so the present application tries to design the gear close to the fixed end structure, that is, the mounting seat 14. Specifically, the mounting seat 14 is installed horizontally, and the upper end is gear meshing. Its transmission force is as follows Fig.13 As shown by the dotted line in the figure, the radial force at the meshing end forms a short-distance reaction force, which prevents the gear from loosening. The driving pinion drives the driven large gear to reduce speed and increase torque. For the axis of the driven gear, the torque is enlarged. The present application achieves the axial short-distance fixation of the driven gear by cleverly giving way to the mounting seat 14, which has a good transmission effect.

[0084] The present invention further provides a pumping device, comprising a pressure regulating device and a pressure regulating valve, wherein the pressure regulating device is the pressure regulating device in the above embodiment.

[0085] The present application solves the following technical problems: how to achieve independent vertical installation of the pressure regulating device, avoid opening holes in the structure of the pumping device or introducing additional large supporting structures, and achieve modular installation of the pressure regulating device, which can be used for semi-automatic pumping equipment to transform the automation function. The present application solves the installation technology and modularization problems of the pressure regulating device. The valve stem clamping design is an important part to solve the pressure regulating function. Semi-automatic equipment on the market is generally a manual mechanism, which is manually operated according to construction requirements. The pressure regulating activity structure design based on the pumping equipment needs to solve the connection clamping function to avoid the loosening phenomenon of the automatic execution action, and at the same time, it is necessary to take into account the modular installation, maintenance and disassembly and other use functions. The pumping equipment needs to regulate the pressure by the power unit to transmit power to the pressure regulating valve. How to prevent the transmission from loosening is a problem that the structure needs to solve, to ensure that the pressure regulating valve will not have pressure control deviation during long-term forward and reverse use. This article needs to achieve the problem of transmission loosening and clearance elimination through the clever and reasonable design of the structure. The pressure regulating device involves power and transmission mechanisms, and needs to be protected as a whole. The protective cover needs to be designed according to the layout of the pressure regulating valve and the pressure regulating transmission to prevent vertical dust from falling and affecting the use of the pressure regulating mechanism.

[0086] The present application realizes the fully automatic pressure regulating function of the pressure valve, and realizes precise, relaxed and stable regulation. The present application can achieve the following technical effects: the pressure regulating device is modularly designed, which is convenient for rapid installation on the valve stem and valve body, and can realize unified maintenance and replacement. In use, it can meet the universal installation of vertical rod structures, meet the installation requirements of a certain cross-sectional size range, and have adjustment space. The transmission part 20 is designed for the pressure regulating valve to be installed in a fixed position, and multiple symmetrical opening grooves are used to transmit the torque power at the upper end to the pressure regulating valve, and it can be easily disassembled and assembled; it can be directly removed vertically, which is very convenient for maintenance and installation operations, and takes into account the role of the vertical compression bearing. The pressure regulating device is driven by a gear structure. The axis of the pressure regulating valve is installed in parallel with the power axis. The driving gear meshes with the driven gear to reduce speed and increase torque. The driven gear is axially pressed to install the bearing. The inner and outer rings of the bearing are pressed and installed through vertical structural parts. A mounting seat is provided below the gear pair to position the two axes, so that the gears are not prone to loosening during meshing. The driving gear and the driven gear are installed close to each other above the mounting seat. The structure has a small axial movement space, which is conducive to the long-term use of the pressure regulating device. The pressure regulating device uses a protective cover structure to protect the lubricated gears, the transmission bayonet parts, the motor output end and other parts to prevent dust from falling and affecting the service life of the device. In particular, the gear meshing is grease lubricated. The protective cover is fastened with screws and can be easily disassembled.

[0087] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0088] The pressure regulating device of the present invention comprises a mounting mechanism 10, a transmission member 20 and a transmission mechanism 30. The mounting mechanism 10 is used to be detachably connected to the valve body 41, and the transmission member 20 is detachably connected to the valve stem 42. Such a setting realizes the installation and disassembly of the pressure regulating device; when the mounting mechanism 10 is installed to the valve body 41, the first docking structure 21 is docked with the second docking structure 43, so that the first docking structure 21 is positioned with the second docking structure 43 in the circumferential direction of the valve stem 42; when the mounting mechanism 10 is detached from the valve body 41, the first docking structure 21 is separated from the second docking structure 43; and the pressure regulating device is connected to the transmission member 20 through the transmission mechanism 30 arranged on the mounting mechanism 10 to drive the transmission member 20 to rotate, so that the transmission member 20 drives the valve stem 42 to rotate together. The pressure regulating device can automatically adjust the opening of the pressure regulating valve 40, with high adjustment accuracy, which solves the problem that the pumping equipment cannot realize automatic pressure regulation. In addition, the pressure regulating device is modularized in structure, can be easily installed on the pressure regulating valve that needs pressure regulation, and has strong applicability.
