[0002] Large pipeline valves are characterized by their large size and high rotational resistance, making them difficult to operate effectively by hand. Current technology typically employs valve turbine housings to drive the valves, thus saving labor. The internal components of the valve turbine housing require lubrication to ensure the stability of the mechanical structure. However, the degraded lubricating oil inside the valve turbine housing must be flushed and replaced at predetermined intervals to prevent damage to the mechanical components.

After injecting cleaning agent, the components are rinsed through a spray system. However, opening the cover for rinsing violates the safety regulations for flammable environments, is time-consuming and labor-intensive, and can also damage the sealing of the valve turbine box. Reassembly may cause oil leakage and other hidden dangers.

[0004] Therefore, it is urgent to propose a solution to the above problems. Utility Model Content

[0018] This utility model proposes a valve turbine box lubricating oil cleaning device, including a flushing pump, a liquid supply component, a flushing pipe, a return pipe, and a recovery component. The liquid supply component has a receiving cavity for holding cleaning agent. The inlet of the flushing pump can communicate with the receiving cavity. One end of the flushing pipe can communicate with the outlet of the flushing pump, and the other end is provided with a multi-hole spray head that can extend into the inner cavity.

[0030] This embodiment proposes a valve turbine housing lubricating oil cleaning device to solve the problems of inconvenient cleaning of failed lubricating oil in valve turbine housings, poor safety, and easy damage to sealing in the prior art.

[0031] like Figures 1-3 As shown, a valve turbine housing lubricating oil cleaning device is used to clean the failed lubricating oil in the inner cavity of a valve turbine housing 100. The valve turbine housing 100 has two positioning holes 101 communicating with the inner cavity. The valve turbine housing lubricating oil cleaning device includes a flushing pump 1, a liquid supply component 2, a flushing pipe 3, a return pipe 4, and a recovery component 5. The liquid supply component 2 has a receiving cavity for holding cleaning agent. The inlet of the flushing pump 1 can communicate with the receiving cavity. One end of the flushing pipe 3 can communicate with the outlet of the flushing pump 1, and the other end is provided with a multi-hole spray head 6, which can extend into the inner cavity. A first quick connector 7 is also movably provided on the flushing pipe 3. The first quick connector 7 is sealed and sleeved on the flushing pipe 3 and can be inserted into one positioning hole 101. The recovery component 5 has a recovery cavity. One end of the return pipe 4 is provided with a second quick connector 8, and the other end communicates with the recovery cavity. The second quick connector 8 can be inserted into another positioning hole 101.

[0032] Understandably, when it is necessary to clean the failed lubricating oil in the inner cavity of the valve turbine housing 100, cleaning can be performed directly using the two inherent positioning holes 101 of the valve turbine housing 100. Both positioning holes 101 are connected to the inner cavity of the valve turbine housing 100. By setting a first quick connector 7 and a second quick connector 8, the first quick connector 7 is inserted into one positioning hole 101 to allow the flushing pipe 3 to extend into the inner cavity in a sealed manner, thereby extending the multi-hole spray head 6 into the inner cavity. The second quick connector 8 is inserted into the other positioning hole 101 and is connected to the recovery chamber through the return pipe 4. By starting the flushing pump 1, the flushing pump 1 pumps the cleaning agent in the accommodating chamber to the multi-hole spray head 6, and sprays it into the inner cavity through the diffusion effect of the multi-hole spray head 6, increasing the coverage area of ​​each component in the inner cavity and cleaning the failed lubricating oil on each component in the inner cavity. The lubricating oil is flushed, and the flushed cleaning agent carries impurities back to the recovery chamber through the return pipe 4 for reuse, reducing the consumption of cleaning agent. This embodiment of the valve turbine box lubricating oil cleaning device utilizes the inherent positioning holes 101 of the valve turbine box 100 to clean the failed lubricating oil, which is very convenient. It does not require disassembling the valve turbine box 100, thus avoiding damage to the sealing of the valve turbine box 100. The device can be quickly connected to the two positioning holes 101 through the first quick connector 7 and the second quick connector 8, which improves the lubricating oil cleaning efficiency. Furthermore, by setting the multi-hole spray head 6, the cleaning area is expanded, thereby improving the thoroughness and efficiency of lubricating oil cleaning. By setting the recovery chamber, the amount of cleaning agent used is saved, improving the economy of the valve turbine box 100 lubricating oil cleaning device.

[0033] For example, the cleaning agent is kerosene. Kerosene has extremely strong solubility, which can quickly remove oil, wax and other stubborn dirt, and it is highly volatile, so it dries quickly after cleaning and does not leave residue, thus improving the reliability of the valve turbine box lubricating oil cleaning device.

[0034] In some optional embodiments, the valve turbine housing lubricating oil cleaning device further includes a return branch pipe 9, one end of which is connected to the end of the flushing pipe 3 away from the orifice spray head 6, and the other end is connected to the recovery chamber. A return valve 10 is provided on the return branch pipe 9. Understandably, after cleaning, cleaning agent remains in the flushing pipe 3. With this setting, opening the return valve 10 allows the residual cleaning agent in the flushing pipe 3 to flow back to the recovery chamber for next use, which helps to save cleaning agent.

[0035] In some optional embodiments, both the first quick-connector 7 and the second quick-connector 8 are provided with external threads, and the first quick-connector 7 and the second quick-connector 8 are threadedly engaged with the two positioning holes 101. This arrangement improves the reliability and sealing of the connection between the first quick-connector 7 and the second quick-connector 8 and the two positioning holes 101, preventing cleaning agent leakage.

[0036] In some optional embodiments, a magnetic filter is provided in the recovery chamber. This arrangement allows the magnetic filter to adsorb iron filings from the returned cleaning agent, preventing it from being used again and improving the economy of the valve turbine box lubricating oil cleaning device. It is worth noting that after filtration by the magnetic filter, the kerosene must be allowed to stand, and then the surface layer of the kerosene is collected, while the oil sediment at the bottom is discharged.

[0037] In some optional embodiments, a first sealing ring is provided on the first quick-connect coupling 7, which abuts against the first quick-connect coupling 7 and a positioning hole 101; a second sealing ring is provided on the second quick-connect coupling 8, which abuts against the second quick-connect coupling 8 and another positioning hole 101. This arrangement further improves the sealing performance of the connection between the first quick-connect coupling 7 and the second quick-connect coupling 8 and the two positioning holes 101, preventing cleaning agent leakage and improving the reliability of the valve turbine box lubricating oil cleaning device.

[0038] For example, both the first and second sealing rings are made of fluororubber. This design prevents the first and second sealing rings from being corroded by kerosene, improving their sealing durability and thus enhancing the reliability of the valve turbine housing lubricating oil cleaning device.

[0039] In some optional embodiments, the multi-hole spray head 6 includes a support portion 61 and a spray portion 62 connected to each other. The support portion 61 has a communicating hole, and the spray portion 62 has a spray chamber. One end of the communicating hole communicates with the flushing pipe 3, and the other end communicates with the spray chamber. The spray portion 62 has an array of multiple spray holes communicating with the spray chamber. This configuration can increase the spray angle of the multi-hole spray head 6, thereby improving the cleaning efficiency and thoroughness of the lubricating oil, and enhancing the structural rationality of the valve turbine box lubricating oil cleaning device.

[0040] In some alternative embodiments, the spray section 62 is spherical. This arrangement further increases the spray angle of the porous spray head 6, improving the structural rationality of the valve turbine housing lubricating oil cleaning device.

[0041] In some optional embodiments, the valve turbine housing lubricant cleaning device further includes an endoscope and a display, which are communicatively connected. The endoscope can extend into the internal cavity. Understandably, before lubricant cleaning, the internal cavity can be inspected using the endoscope to record areas with significant lubricant residue. Before cleaning, the multi-hole spray head 6 can be extended to a position near the recorded area for cleaning, helping to eliminate stubborn lubricant residue. Furthermore, after cleaning, the endoscope can be inserted into the internal cavity to check if the cleaning is thorough, thereby improving the reliability and usability of the valve turbine housing lubricant cleaning device.

[0042] In some optional embodiments, the valve turbine housing lubricant cleaning device also includes a PWM (Pulse Width Modulation) controller, which is electrically connected to the flushing pump 1. Understandably, the PWM controller allows for the planning of the power of the flushing pump 1 during the flushing process, which helps to maximize the thoroughness and efficiency of flushing while saving energy, thereby improving the user experience of the valve turbine housing lubricant cleaning device.

[0043] In some optional embodiments, the valve turbine housing lubricating oil cleaning device also includes a hot air blower, and the inlet of the flushing pump 1 can be connected to the hot air blower. Understandably, after the lubricating oil cleaning is completed, the flushing pump 1 can be connected to the hot air blower to introduce hot air into the inner cavity for drying, so that the valve turbine housing 100 can be put into operation as soon as possible, thereby improving the overall functionality of the valve turbine housing lubricating oil cleaning device.

[0044] It is worth noting that after the hot air blower is powered on, the blower in the hot air blows air into the heater, allowing the air to pass evenly through the inside and outside of the spiral heating wire. The heat generated by the heating wire after being powered on exchanges heat with the passing cold air, thereby raising the temperature of the air at the outlet of the hot air blower. Any commercially available, mature product can be used for the hot air blower; this embodiment does not impose excessive restrictions on its specific structure.

[0045] For example, flushing pump 1 is a KNFNMP830 diaphragm pump. This configuration improves the flushing intensity and explosion resistance of flushing pump 1, thereby enhancing the reliability of the valve turbine housing lubricating oil cleaning device. Of course, in other embodiments, flushing pump 1 can also be other types of pumps, which can be set as needed according to actual conditions, and no further restrictions are imposed here.

[0046] For example, both the flushing pipe 3 and the return pipe 4 are universal flexible hoses. This arrangement enhances the flexibility of the flushing pipe 3 and the return pipe 4, facilitating their arrangement in complex environments and improving the usability of the valve turbine housing lubricant cleaning device.

[0047] The working process of the valve turbine box lubricating oil cleaning device in this embodiment is as follows:

[0048] Remove the positioning bolt in the positioning hole 101, screw the first quick connector 7 into the positioning hole 101, connect the inlet of the flushing pump 1 to the atmosphere, start the flushing pump 1 and introduce 0.4MPa compressed air to maintain pressure for 5 minutes, and check the sealing of the inner cavity.

[0049] Remove the first quick connector 7, use an endoscope to inspect the cavity, then install the first quick connector 7 and the second quick connector 8, connect the inlet of the flushing pump 1 to the accommodating cavity, and start the flushing pump 1 to begin flushing.

[0050] During the rinsing process, gradually increase the rinsing flow rate and rotate the worm gear of the valve turbine box 100 to help the cleaning agent enter between the components.

[0051] After rinsing, disconnect the first quick-connect connector 7 and the second quick-connect connector 8, use an endoscope to check the cleaning results in the inner cavity, and connect the inlet of the rinsing pump 1 to the hot air blower to blow hot air into the inner cavity to assist in the drying of the components.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
