Abstract
Description
Technical Field
[0001] The utility model belongs to the field of oil mist lubrication, and particularly relates to a new type of oil mist on-off instrument. Background Art
[0002] Oil mist lubrication is a lubrication method that atomizes lubricating oil into tiny particles (usually in the range of 1 - 3 microns) and uses compressed air to transport it to the equipment parts that need lubrication. It has the advantages of good lubrication effect, good heat dissipation effect, and simple and reliable structure.
[0003] In an oil mist lubrication system, the oil mist on-off instrument is installed on the input pipeline at the upper end of the pump. A fan blade device is usually arranged inside the oil mist on-off instrument. When the oil mist passes through the oil mist on-off instrument, it drives the fan blade device to rotate, thereby detecting the transportation condition of the oil mist. Due to the long transportation distance of the oil mist, the oil mist pressure will be lost. Especially for the pump at the end of the oil mist lubrication system, the oil mist pressure will become smaller. And when the oil mist passes through the oil mist on-off instrument, the oil mist will condense into oil droplets and adhere to the fan blade device. The condensed oil accumulates on the fan blade device. When it accumulates to a certain extent, the oil will cause a certain obstruction to the fan blade device, and the fan blade device will stop rotating. However, at this time, the oil mist is still flowing normally, which will lead to misjudgment by maintenance personnel, thinking that the oil circuit is blocked, and then shutting down for maintenance, resulting in an embarrassing situation and causing greater trouble and losses. Content of the Utility Model
[0004] To solve the problems raised in the above background art, the utility model provides a new type of oil mist on-off instrument, which adds a small hole inside the oil mist on-off instrument. The condensed oil droplets can flow out of the fan blade device through this hole, enabling the oil mist on-off instrument to start under a smaller oil mist pressure and ensuring the accuracy of detection.
[0005] To achieve the above purpose, the specific technical solution of the utility model is as follows:
[0006] A new type of oil mist on-off instrument, including an on-off instrument housing. Upper cover devices and lower cover devices are fixedly connected to both ends of the on-off instrument housing. An air inlet valve is connected to the upper end of the upper cover device, and an air outlet valve is connected to the lower end of the lower cover device. A fan mounting bracket is fixedly connected to the lower end of the upper cover device, and a fan blade device is rotatably connected to the fan mounting bracket. The fan blade device is located inside the on-off instrument housing.
[0007] As a further setting of the above solution, observation windows are opened on both sides of the on-off instrument housing. The observation windows are located on both sides of the fan blade device, and the rotation condition of the fan blade device can be clearly observed through the observation windows.
[0008] As a further setting of the above solution, the upper cover device includes an upper cover plate. A fixing block is fixedly arranged at the lower end of the upper cover plate. An installation arc groove is formed in the fixing block. An air inlet hole penetrating upward is formed in the installation arc groove, and the air inlet hole is correspondingly communicated with an air inlet valve.
[0009] As a further setting of the above solution, the fan mounting bracket includes a fixing ring. A ventilation hole is formed in the left side of the upper end of the fixing ring, and the ventilation hole is correspondingly communicated with the air inlet hole. Symmetrical rotating brackets are arranged on both sides of the inner wall surface of the fixing ring, and the fan blade device is rotatably connected between the rotating brackets.
[0010] As a further setting of the above solution, a liquid guide groove is formed at the central position of the inner wall surface of the fixing ring. The liquid guide groove is located between the rotating brackets. A vertical liquid leakage hole penetrating downward is formed at the lower end of the fixing ring, and the liquid leakage hole is directly above the air outlet valve.
[0011] The utility model has the following beneficial effects:
[0012] The oil mist is input into the on-off instrument housing through the air inlet valve. The oil mist passes through the air inlet hole and the ventilation hole and contacts the fan blade device. The oil mist blows the fan blade device to rotate, so as to judge the transportation condition of the oil mist. After the oil mist condenses on the fan blade device, it falls to the lower end of the inner wall ring surface of the fixing ring. The oil liquid flows out of the fan mounting bracket through the liquid leakage hole under the action of the liquid guide groove, and finally flows out from the air outlet valve, avoiding the retention of the oil liquid, reducing the rotation resistance of the fan blade device, ensuring that the fan blade device can rotate under a smaller oil mist pressure, and ensuring the accuracy of the detection.

Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.
[0020] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the attached Figures 1 - 5 drawings and describe this application in detail with reference to the embodiments.
[0021] As Figure 1 shown in Figure 2 figures, a new type of oil mist on-off instrument, both ends of the on-off instrument housing 1 are fixedly connected with an upper cover device 2 and a lower cover device 3. An air inlet valve 4 is connected to the upper end of the upper cover device 2, and an air outlet valve 5 is connected to the lower end of the lower cover device 3. A fan mounting bracket 6 is fixedly connected to the lower end of the upper cover device 2. A fan blade device 7 is rotatably connected to the fan mounting bracket 6. The fan blade device 7 is located inside the on-off instrument housing 1. Observation windows 101 are opened on both sides of the on-off instrument housing 1. The observation windows 101 are located on both sides of the fan blade device 7. Through the observation window 7, the rotation of the fan blade device 7 can be clearly observed.
[0022] As Figure 3 shown in
[0023] figures, the upper cover device 2 includes an upper cover plate 201. A fixing block 202 is fixedly arranged at the lower end of the upper cover plate 201. An installation arc groove 203 is opened in the fixing block 202. An air inlet hole 204 penetrating upward is opened in the installation arc groove 203. The air inlet hole 204 is correspondingly communicated with the air inlet valve 4.
[0023] As Figure 4 shown in Figure 5 figures, the fan mounting bracket 6 includes a fixing ring 601. The fixing ring 601 is fixedly installed in the installation arc groove 203. An air vent hole 6011 is opened on the left side of the upper end of the fixing ring 301. The air vent hole 6011 is correspondingly communicated with the air inlet hole 204. Symmetrical rotating brackets 602 are arranged on both sides of the inner wall surface of the fixing ring 201. The fan blade device 7 is rotatably connected between the rotating brackets 602. A liquid guide groove 6013 is opened at the central position of the inner wall surface of the fixing ring 601. The liquid guide groove 6013 is located between the rotating brackets 602.
