Description

Technical Field

[0001] This utility model relates to the field of pneumatic and hydraulic equipment positioner technology, specifically a quick-release pneumatic and hydraulic equipment positioner. Background Technology

[0002] Valve positioners are classified into electric valve positioners, pneumatic valve positioners, and intelligent valve positioners according to their structure. They are used in conjunction with control valves and are the main accessories of control valves. They receive the output signal from the controller and use the output signal to control the control valve. After the valve moves, the positioner provides feedback and plays a certain role in ensuring the performance of the control valve. However, positioners often malfunction during use, which can affect the normal operation of the control valve. In order to ensure continuous and stable production, once the positioner malfunctions, it needs to be repaired and adjusted quickly. However, most existing positioners are fixed with screws and bolts, which requires a lot of time to install and disassemble, making installation troublesome and disassembly and maintenance inconvenient. Utility Model Content

[0003] The purpose of this utility model is to provide a quick-release positioner for pneumatic and hydraulic equipment, so as to solve the problem mentioned in the background art that the positioner is not easy to install and replace when it is damaged.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick-release pneumatic-hydraulic equipment positioner, comprising a positioner body, a mounting plate fitted to the side surface of the positioner body, and a fixing screw threadedly connected between the mounting plate and the positioner body, a mounting fixing plate provided on one side of the mounting plate, the mounting fixing plate having an inverted T-shaped design, a sliding groove with a stepped design on the outer surface of the mounting fixing plate, and a plug-in mechanism provided between the mounting plate and the mounting fixing plate, the positioner body being quickly installed on the side surface of the mounting fixing plate through the plug-in mechanism.

[0005] Preferably, the insertion mechanism includes a slider groove, which is fixedly installed on the side surface of the mounting plate, and the outer surface of the mounting plate is in contact with the outer surface of the mounting fixing plate, and the slider groove is engaged with the mounting fixing plate.

[0006] By adopting the above technical solution, the positioner body and the mounting plate can be quickly inserted into the side surface of the mounting plate. The sliding groove prevents the mounting plate from shifting during insertion, facilitating the installation and removal of the positioner body and allowing for rapid replacement, thus ensuring continuous and stable production.

[0007] Preferably, a pull bolt is fitted inside the slide groove, and the pull bolt is slidably connected to the slide groove, with one end of the outer surface of the pull bolt not touching the outer surface of the mounting plate.

[0008] Using the above technical solution, the pull bolt can move inside the slide groove, making it convenient to fix the mounting plate to the outer surface of valves of different sizes.

[0009] Preferably, a threaded pushing mechanism is provided between the bolt and the mounting plate, and the mounting plate is fixedly installed on the outer surface of the valve by means of the threaded pushing mechanism.

[0010] By adopting the above technical solution, the mounting plate can be fixed to the outer surface of valves of different thicknesses by means of bolts and jacks, and the positioner body can be fixed to one side of the valve.

[0011] Preferably, the threaded pushing mechanism includes: a bolt, the bolt having a U-shaped design, and a nut being threaded onto the end of the bolt away from the pull bolt; the outer surface of the bolt penetrating the outer surface of the pull bolt, and the outer surface of the pull bolt fitting against the outer surface of the bolt; a fixing plate being threaded onto the outer surface of the bolt, and the fixing plate being slidably connected to the bolt; the outer surface of the fixing plate fitting against the outer surface of the valve, and the outer surface of the fixing plate fitting against the outer surface of the nut.

[0012] Using the above technical solution, the U-shaped design of the bolt allows the bolt to be inserted into the side surface of the valve. Then, the fixing plate can be inserted into the outer surface of the bolt, and the nut can be screwed into the bolt to push the fixing plate to move, so that the fixing plate clamps the valve with the mounting plate. The bolt can also be removed from the bolt. By replacing the bolt and the fixing plate, it can be adapted to the outer surface of valves of different sizes and thicknesses.

[0013] Preferably, an elastic thread mechanism is provided between the mounting plate and the mounting fixing plate, so that after the mounting fixing plate is fixed to the valve by the elastic thread mechanism, the mounting plate can be fixed to the side surface of the mounting fixing plate.

[0014] By adopting the above technical solution, when the mounting plate is fixed on the outer surface of the valve, the support plate will be squeezed and pressed against the mounting plate, so that the pin can move and engage with the positioning groove, allowing the mounting plate to be fixedly installed on the side surface of the mounting plate, reducing the probability of accidentally pulling out the positioner body.

[0015] Preferably, the elastic threaded mechanism includes: a pin, which is slidably installed inside the mounting plate, and a spring is provided between the mounting plate and the pin; a threaded connector is fixedly installed at the end of the pin away from the mounting plate, and a support plate is threadedly installed on the outer surface of the threaded connector; the outer surface of the threaded connector is in contact with one end of the spring; and a positioning groove is provided at the end of the mounting plate near the support plate, and the positioning groove engages with the pin.

[0016] Using the above technical solution, when the positioner body needs to be removed due to malfunction, an Allen wrench can be inserted into the threaded connector and rotated. As the threaded connector rotates, the pin will disengage from the positioning groove, allowing the positioner body and the mounting plate to be removed for replacement. After replacement, the threaded connector can be turned to reset the pin, controlling the fixing and separation of the mounting plate and the mounting fixing plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the positioner for this quick-release pneumatic-hydraulic equipment:

[0018] 1. When the positioner body fails and cannot be used, simply use a tool to turn the threaded connector to remove the positioner body and mounting plate from the mounting plate. Let the mounting plate move along the direction of the slider groove. The slider groove prevents the mounting plate from moving randomly when it is inserted into the mounting plate, so as to facilitate quick replacement and maintenance of the positioner body.

[0019] 2. When installing the mounting plate, the position of the pull bolt in the slide groove can be adjusted so that the bolt can be accurately aligned with both sides of the outer surface of the valve. Bolts of different widths can be replaced to adapt to the outer surface of valves with different wall thicknesses. Then, the fixing plate can be inserted into the bolt and the nut can be screwed in. By tightening the nut, the mounting plate is installed on the outer surface of the valve, which makes it convenient to install and fix the mounting plate on the outer surface of valves with different thicknesses and sizes.

[0020] 3. As the nut is screwed into the bolt, the retaining plate will be pushed and clamp the valve with the mounting plate. During the tightening process, the support plate will gradually approach the mounting plate and push out the pin to slide inside the mounting plate, so that the pin engages with the positioning groove, fixing the mounting plate to the side surface of the mounting plate. This fixes the mounting plate during installation and allows the connection and separation of the mounting plate and the mounting plate to be controlled by tightening the threaded connector. This prevents the positioner body and the mounting plate from being arbitrarily removed from the mounting plate, reducing the risk of the positioner body falling out accidentally. The mounting plate can also be fixed during the installation of the mounting plate. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a quick-release pneumatic and hydraulic equipment positioner, including a positioner body 1, a mounting plate 2 attached to the side surface of the positioner body 1, and a fixing screw 15 threadedly connected between the mounting plate 2 and the positioner body 1, a mounting fixing plate 4 provided on one side of the mounting plate 2, and the mounting fixing plate 4 has an inverted T-shaped design, and a sliding groove 5 is provided on the outer surface of the mounting fixing plate 4, and the sliding groove 5 has a stepped design, and a plug-in mechanism is provided between the mounting plate 2 and the mounting fixing plate 4, so that the positioner body 1 can be quickly installed on the side surface of the mounting fixing plate 4 through the plug-in mechanism. The plug-in mechanism includes a slider groove 3, which is fixedly installed on the side surface of the mounting plate 2, and the outer surface of the mounting plate 2 is attached to the outer surface of the mounting fixing plate 4, and the slider groove 3 is engaged with the mounting fixing plate 4.

[0030] The mounting plate 2 is fixed to the positioner body 1 by fixing screw 15, which makes it convenient to fix the positioner body 1 to the side surface of the mounting plate 4 later. The sliding groove 3 prevents the mounting plate 2 from moving randomly when it is inserted into the outer surface of the mounting plate 4, so that the positioner body 1 can be easily removed from the outer surface of the valve for replacement and maintenance when it is damaged.

[0031] A pull bolt 6 is installed inside the slide groove 5, and the pull bolt 6 is slidably connected to the slide groove 5. One end of the outer surface of the pull bolt 6 does not fit against the outer surface of the mounting plate 2.

[0032] During installation, the position of the pull bolt 6 in the slide groove 5 can be adjusted to accommodate valves of different widths and sizes, allowing the bolt 7 to be inserted into the outer surface of the valve.

[0033] A threaded pushing mechanism is provided between the bolt 6 and the mounting plate 4, which fixes the mounting plate 4 to the outer surface of the valve.

[0034] When the side surface of the valve is too thick, the bolt 7 can be removed from the pull bolt 6 and replaced with a wider bolt 7 so that the bolt 7 can be inserted into the outer surface of the valve of different thicknesses.

[0035] The threaded pushing mechanism includes: a bolt 7, which is U-shaped, and a nut 10 is threaded on the end of the bolt 7 away from the pull bolt 6. The outer surface of the bolt 7 penetrates the outer surface of the pull bolt 6, and the outer surface of the pull bolt 6 is in contact with the outer surface of the bolt 7. A fixing plate 8 is installed through the outer surface of the bolt 7, and the fixing plate 8 is slidably connected to the bolt 7. The outer surface of the fixing plate 8 is in contact with the outer surface of the valve, and the outer surface of the fixing plate 8 is in contact with the outer surface of the nut 10.

[0036] After adjusting the position of the pull bolt 6, the bolt 7 can be inserted into the outer surfaces of both sides of the valve. Then, the fixing plate 8 can be inserted into the inside of the bolt 7, and the nut 10 can be screwed into the outer surface of the bolt 7. Together with the fixing plate 8 and the mounting plate 4, the mounting plate 4 is clamped and fixed to the outer surface of the valve, which can adapt to valves of different widths and sizes.

[0037] An elastic thread mechanism is provided between the mounting plate 2 and the mounting plate 4. After the mounting plate 4 is fixed to the valve by the elastic thread mechanism, the mounting plate 2 can be fixed to the side surface of the mounting plate 4.

[0038] As the nut 10 is screwed into the bolt 7 and tightened, the support plate 9 will gradually approach the mounting plate 4, compressing the spring 12, allowing the pin 11 to be inserted into the positioning groove 14, and fixing the mounting plate 2 to the side surface of the mounting plate 4. After the mounting plate 4 is fixed to the valve exterior, the mounting plate 2 can be secured.

[0039] The elastic thread mechanism includes: a pin 11, which is slidably installed inside the mounting plate 4, and a spring 12 is provided between the mounting plate 4 and the pin 11. A threaded pin 13 is fixedly installed at the end of the pin 11 away from the mounting plate 2, and a support plate 9 is threadedly installed on the outer surface of the threaded pin 13.

A positioning groove 14 is provided at the end of the mounting plate 2 near the support plate 9, and the positioning groove 14 is engaged with the pin 11.

[0040] When the entire assembly needs to be disassembled, the nut 10 is removed from the bolt 7, and the spring 12 pushes the support plate 9 back into place. When the positioner body 1 malfunctions and needs to be replaced, a tool can be inserted into the threaded connector 13 and rotated to disengage the pin 11 from the positioning groove 14. The positioner body 1 and the mounting plate 2 can then be pulled out from the mounting plate 4. After that, the usable positioner body 1 and the mounting plate 2 can be reinstalled and the pin 11 can be screwed back in to secure it, effectively preventing the positioner body 1 from detaching due to accidental contact.
