Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary flushing tools for fire-resistant fuel engines, and specifically relates to a flushing plate for flushing fire-resistant fuel engines. Background Technology

[0002] In the field of fire-resistant oil system flushing, especially in the first phase of the Huizhou Taipingling Nuclear Power Project, the flushing scope of the fire-resistant oil system covers the high-pressure main steam regulating valve and the medium-pressure combined steam valve, which is characterized by complex system and numerous flushing pipelines.

[0003] In traditional flushing processes, to avoid clogging of solenoid valves and servo valves with fire-resistant fuel, a hydraulic external circulation and staged flushing method is typically used. However, this method results in a long flushing time, making it difficult to meet the project's timeline requirements. Therefore, a more efficient flushing solution is urgently needed to address this issue. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a flushing plate for rinsing fire-resistant fuel engines, which solves the problem that the flushing time of fire-resistant fuel systems is too long in the prior art and it is difficult to meet the project schedule requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A flushing plate for flushing a fire-resistant oil motor includes a plate body prefabricated according to the installation position of the oil motor. Mounting holes are drilled through at the four corners of the front surface of the plate body. An oil inlet hole, an oil return hole, and multiple sealing grooves are also drilled through the front surface of the plate body. O-rings are embedded in the openings of the sealing grooves, the oil inlet hole, and the oil return hole. Internal threads are provided on the inner rear sidewalls of the oil inlet hole and the oil return hole, respectively for connecting to external fire-resistant oil supply lines and external oil return lines. The distribution of the oil inlet hole and the oil return hole precisely corresponds to any set of inlet and outlet holes of the oil motor. The distribution of the sealing grooves corresponds one-to-one with the remaining connection holes on the oil motor, achieving sealing and plugging of interfaces outside the flushing path.

[0007] In the above technical solution, the thickness of the plate is 15mm-20mm.

[0008] In the above technical solution, the plate body is a stainless steel plate body.

[0009] In the above technical solution, the O-ring is a fluororubber sealing ring.

[0010] In the above technical solution, the depth of the sealing groove is less than 1 mm of the thickness of the O-ring.

[0011] The present invention provides a rinsing plate for rinsing fuel-powered motors, which, compared with the prior art, has the following advantages:

[0012] This invention precisely adapts to the interface dimensions and positions of the solenoid valve and servo valve on the hydraulic actuator, using the same stainless steel material and fluororubber O-rings for sealing. This ensures both tight installation and prevents fire-resistant oil leakage. By replacing the solenoid valve and servo valve, it eliminates the need for numerous temporary pipelines required for traditional flushing, allowing the fire-resistant oil to directly enter the hydraulic actuator through the inlet and then flow out through the return hole to form a circulation. This significantly shortens the flushing path, improves flushing efficiency, reduces flushing time, and effectively protects the internal components of the hydraulic actuator. Furthermore, the matching design of the sealing groove and O-ring (the sealing groove depth is less than the O-ring thickness by 1mm) ensures a good seal while preventing excessive compression of the O-ring, extending its service life. Overall, it solves the problems of low efficiency and long time consumption associated with traditional external circulation and staged flushing methods, demonstrating strong adaptability and practical reliability.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0019] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-4 This utility model provides a technical solution:

[0020] A flushing plate for flushing a fire-resistant oil motor includes a plate body 1, which is prefabricated according to the installation position of the oil motor. The plate body 1 has mounting holes 11 through-through at the four corners of its front surface, and oil inlet holes 2, oil return holes 3 and multiple sealing grooves 4 through-through on the front surface. O-ring seals 5 are embedded in the openings of the sealing grooves 4, oil inlet holes 2 and oil return holes 3. The inner sidewalls of the rear ends of oil inlet holes 2 and oil return holes 3 are provided with internal threads, which are used to connect external fire-resistant oil supply lines and external oil return lines, respectively.

[0021] The distribution positions of the oil inlet hole 2 and the oil return hole 3 correspond precisely to any set of oil inlet and outlet holes of the hydraulic motor, and the distribution positions of the sealing groove 4 correspond one-to-one with the remaining connection holes on the hydraulic motor, thereby achieving sealing and plugging of the non-flushing path interface.

[0022] Determining the size of the flushing plate: To use the flushing plate for fire-resistant oil flushing, the size and position of the oil inlet and return holes of the solenoid valve and servo valve on the steam valve hydraulic actuator must first be measured. Then, the flushing plate is processed according to the measurement data. The specific size of the flushing plate needs to be adjusted according to the measured dimensions.

[0023] Flushing plate processing: The flushing plate material is selected from the same stainless steel material as the fire-resistant oil pipe material of the hydraulic actuator. During processing, ensure that the positions of the oil inlet hole 2, oil outlet hole 3, and multiple sealing grooves 4 correspond to the installation position. The O-ring seal material is generally fluororubber, used to seal the connection of each hole to ensure the sealing effect of the flushing plate during use. When using a flushing plate for flushing, because there is no throttling orifice, the flushing pressure is lower than the normal operating pressure of the system, so the flushing plate thickness should be selected between 15mm and 20mm.

[0024] Finally, to ensure a good seal while preventing the O-ring 5 from being over-compressed after installation on the flushing plate, thus affecting its service life, the depth of the sealing groove 4 needs to be 1mm less than the thickness of the O-ring 5.

[0025] For example, the depth of the sealing groove 4 is set to 2mm-3mm, and the thickness of the O-ring is set to 3mm-5mm. After installation, the O-ring can generate a compression of 1mm, which ensures that the O-ring fully fits the sealing surface without causing elastic failure due to excessive deformation.

[0026] For example, if the groove is deep (e.g., 3mm-4mm), a 4mm-5mm O-ring can be used to achieve a reliable seal through compression of about 1mm.

[0027] Meanwhile, fluororubber itself possesses excellent oil resistance, high temperature resistance, and elastic recovery properties. Within the aforementioned thickness and compression range, it can adapt to oil impacts and temperature changes during flushing, while maintaining a sealed state after deformation for a long period, preventing oil leakage. In practical applications, it is also necessary to adapt and adjust according to the specific dimensions of the sealing groove 4 to ensure that the O-ring 5 and the sealing groove 4 form an interference fit to achieve the best sealing effect.

[0028] Working principle: When installing the flushing plate, firstly, accurately measure the size and position of the oil inlet and return holes and remaining connection holes of the solenoid valve and servo valve on the steam inlet valve hydraulic motor, as well as the position of the steam inlet valve bolt hole. Then, process the plate body 1 using the same stainless steel material as the hydraulic motor fire-resistant oil pipe. Open the mounting holes 11 corresponding to the steam inlet valve bolt holes at the four corners of its front surface, open the oil inlet hole 2 and oil return hole 3 corresponding to the oil inlet and outlet holes of the hydraulic motor, and open multiple sealing grooves 4 corresponding to the remaining connection holes of the hydraulic motor. Next, insert the fluororubber O-ring seal 5 into the opening of the oil inlet hole 2, oil return hole 3 and sealing groove 4, and ensure that the depth of the sealing groove 4 is 1mm smaller than the thickness of the O-ring seal 5.

[0029] Finally, according to the original installation position of the solenoid valve or servo valve, the flushing plate is fixed to the hydraulic actuator with bolts through the mounting hole 11, so that the oil inlet hole 2 and the oil return hole 3 are respectively connected to the oil inlet and outlet holes of the hydraulic actuator, and the sealing groove 4 is connected to the remaining connection hole of the hydraulic actuator. At this time, the O-ring seal is deformed by pressure to achieve a seal. During the flushing operation, the oil inlet hole 2 is connected to the external fire-resistant oil supply pipeline to deliver fire-resistant oil to the hydraulic actuator; the oil return hole 3 is connected to the external oil return pipeline to discharge the fire-resistant oil that has been flushed and carries impurities, forming a flushing cycle.

[0030] Compared with existing flushing methods, this flushing plate precisely adapts to the interface size and position of the solenoid valve and servo valve on the hydraulic actuator. It is made of the same stainless steel material and sealed with fluororubber O-rings 5, which ensures both tight installation and avoids leakage of fire-resistant oil. After replacing the solenoid valve and servo valve, it eliminates the need for a large number of temporary pipelines required by traditional flushing. The fire-resistant oil can directly enter the hydraulic actuator through the oil inlet 2 and then flow out through the oil return hole 3 to form a circulation, which greatly shortens the flushing path, improves flushing efficiency, shortens flushing time, and effectively protects the internal components of the hydraulic actuator. At the same time, the matching design of the sealing groove 4 and the O-ring 5 (the depth of the sealing groove 4 is 1mm less than the thickness of the O-ring 5) ensures the sealing effect while avoiding excessive compression of the O-ring 5, thus extending its service life. Overall, it solves the problems of low efficiency and long time consumption of traditional external circulation and staged flushing, and is highly adaptable and reliable.
