Description

Technical Field

[0001] The utility model relates to the technical field of oil cups, in particular to a dual-purpose oil cup and an oil replenishing device. Background Art

[0002] Adding and subtracting cocks, exchanging cocks, and air and gas strokes are all important components of the heating system. Due to the need for sealing and reducing friction, a large number of oil cups are distributed on the upper part of each device for replenishing oil and performing lubrication operations regularly. Failure to lubricate the cock in time will cause gas leakage, and failure to lubricate the stroke parts in time will cause increased equipment wear. Therefore, it is necessary to regularly add sufficient oil to the cock core and use oil cups to replenish oil according to the lubrication or leakage situation during the inspection process to ensure the tightness of the equipment and reduce wear. The two processes require the use of different devices respectively. For example, when filling oil into the cock core, a pressure injection oil cup is required, such as the straight-through pressure injection oil cup provided in Chinese patent document CN216844078 U (application number 202220398781.4). This oil cup cannot store oil and can only be used as a tool for filling lubricating oil; the oil cup used in the inspection process needs to be installed on the cock or stroke device during use, such as the screw-on oil cup provided in Chinese patent document CN 204756391 U (application number 201520475402.7). This oil cup can only squeeze the internal stored oil into the device through the screw-on cap, and cannot be directly filled.

[0003] The current method primarily involves manually removing the oil cup and connecting it to a manual refueling nozzle to refuel the cock. This process, including refueling the cock core, disassembling and installing the oil cup, and refueling the cock, consumes considerable labor time. The main time and labor consuming aspects of the current method are: 1. Refueling cup disassembly and installation; 2. Installing and removing the refueling pipe and cock refueling port; 3. Manually refueling the oil cup; 4. Refueling cup disassembly; and 5. Refueling and rotating the cock at each refueling port during refueling. Due to the large number of oil cups and the long labor and physical strain of the current refueling method, each refueling operation is labor-intensive and physically demanding. This is particularly exacerbated by the high temperatures in basements and flue corridors during summer, which exacerbates the operating environment and the difficulty of these long and physically demanding tasks.

[0004] The defects of the above-mentioned existing devices and the defects that exist during use seriously restrict the refueling speed, efficiency and labor intensity. In order to completely solve the above problems, it is necessary to design a fast refueling device to improve work efficiency and reduce labor intensity. Utility Model Content

[0005] The purpose of the present utility model is to overcome the deficiencies of the above-mentioned prior art and to provide a dual-purpose oil cup and oil filling device. The dual-purpose oil cup can realize pressure injection and screw-cap refueling. There is no need to install or remove the dual-purpose oil cup during use, which greatly improves the convenience of cock oil filling or stroke oil filling operations.

[0006] In order to achieve the above technical effects, the present invention adopts the following technical solutions:

[0007] A dual-purpose oil cup includes a cup cover and a cup body. The upper end of the cup body is threadedly connected to the lower end of the cup cover, and the lower end of the cup body is provided with an oil outlet pipe.

[0008] The outer wall of the oil outlet pipe is provided with an external thread.

[0009] An oil filling pipe is fixed on the outer side of the top surface of the cup cover, and an oil filling hole connected to the oil filling pipe is opened at the upper end of the cup cover.

[0010] A one-way valve is provided in the oil filling hole.

[0011] The cup cover is provided with a first force applying portion for facilitating the operator to rotate the cup cover, and the cup body is provided with a second force applying portion for facilitating the operator to rotate the cup body.

[0012] The dual-purpose oil cup provided by the utility model can be connected to an external injection device through the oil filling hole. While injecting lubricating oil into the cock or stroke by injection, it can also fill the interior of the cup with lubricating oil. After the external injection device is removed, the one-way valve in the oil filling hole is used to ensure that the lubricating oil inside the cup does not overflow. During the operator's inspection, the force-applying part can be used to rotate the cup cover to inject the lubricating oil stored in the cup. The dual-purpose oil cup provided by the utility model is used to tighten and install it at the lubricating oil filling port of the cock or stroke using the external thread provided on the outer wall of the oil outlet pipe. In both oil filling methods, there is no need to remove the oil cup, which greatly improves the operating efficiency and reduces the labor burden of the operator.

[0013] At the same time, the first force-applying part and the second force-applying part are provided, thereby improving the efficiency of the operator in rotating the cup cover or the cup body during the inspection process.

[0014] Preferably, the outer side of the cup body is provided with a scale. Since the injection operation requires a certain amount of pressure, the oil cup needs to have a certain pressure-bearing capacity. It is not convenient to replace its material with a transparent material or to provide a transparent viewing window on the cup body. By marking the scale on the outer side of the cup body, the operator can know the distance the cup cover has been advanced and quickly determine the amount of lubricating oil remaining in the cup body. When the cup cover has been screwed in a certain amount, the operator can promptly refill the oil.

[0015] Preferably, the first force-exerting portion is a first vertical line provided on the side wall of the cup cover, and the second force-exerting portion is a second vertical line provided on the side wall of the cup body.

[0016] Preferably, the first force-applying part is a first nut fixed to the top of the cup cover, and the second force-applying part is a second nut fixed to the lower end of the cup body.

[0017] Further preferably, the first nut is sleeved on the outside of the oil filling pipe, and the second nut is sleeved on the outside of the oil outlet pipe.

[0018] The utility model also provides an oil replenishing device, including an oil replenishing pipeline and a dual-purpose oil cup.

[0019] The dual-purpose oil cup is the dual-purpose oil cup provided by the above technical solution, wherein the oil filling pipe is a quick connector male head,

[0020] The oil supply pipeline includes an oil supply main pipe, a tee, an oil supply branch pipe and a quick connector female in sequence according to the fluid flow direction.

[0021] The inlet end of the oil supply main pipe is connected to an external injection device. Two oil supply branches are provided on the oil supply pipeline, and the oil supply device includes two dual-purpose oil cups.

[0022] The oil replenishing device provided by the utility model utilizes a dual-purpose oil cup and an oil replenishing pipeline to fill lubricating oil into two cock cores at one time, which not only reduces the two separate filling processes to one filling process, but also during the one filling process, the cock only needs to be rotated once, which greatly reduces the operating burden of the operator.

[0023] Preferably, a flow control valve is provided on the oil supply branch pipe. Since the lubricant consumption rates of the two cocks may be different, if the two cocks are filled with lubricant at the same rate, one cock may be fully filled while the other cock is still short of lubricant. Therefore, the flow control valve is provided to control the lubricant filling rate to ensure that both cocks are filled at the same time.

[0024] Beneficial effects of the utility model:

[0025] 1. The dual-purpose oil cup provided by the present invention can be connected to an external injection device through the oil filling hole. While injecting lubricating oil into the cock or stroke, it can also fill the cup body with lubricating oil. After the external injection device is removed, the one-way valve in the oil filling hole is used to ensure that the lubricating oil inside the cup body does not overflow. During the operator's inspection, the force-applying part can be used to rotate the cup cover to inject the lubricating oil stored in the cup body. The dual-purpose oil cup provided by the present invention is used, and the external thread provided on the outer wall of the oil outlet pipe is used to tighten and install it at the lubricating oil filling port of the cock or stroke. There is no need to remove the oil cup in both oil filling methods, which greatly improves the operating efficiency and reduces the labor burden of the operator.

[0026] 2. The oil replenishing device provided by the utility model utilizes a dual-purpose oil cup and an oil replenishing pipeline to fill lubricating oil into two cock cores at one time, which not only reduces the two separate filling processes to one filling, but also during the one filling process, the cock only needs to be rotated once, which greatly reduces the operating burden of the operator.

DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] Example 1:

[0032] A dual-purpose oil cup, comprising a cup cover 2 and a cup body 1, wherein the upper end of the cup body 1 is threadedly connected to the lower end of the cup cover 2, and an oil outlet pipe 4 is provided at the lower end of the cup body 1.

[0033] The outer wall of the oil outlet pipe 4 is provided with an external thread 7.

[0034] An oil filling pipe 3 is fixed to the outer side of the top surface of the cup cover 2, and an oil filling hole connected to the oil filling pipe 3 is opened at the upper end of the cup cover 2.

[0035] A one-way valve is provided in the oil filling hole.

[0036] The cup cover 2 is provided with a first force applying portion 5 for facilitating the operator to rotate the cup cover 2 , and the cup body 1 is provided with a second force applying portion 6 for facilitating the operator to rotate the cup body 1 .

[0037] In this embodiment, the first force applying portion 5 is a first vertical line provided on the side wall of the cup cover 2 , and the second force applying portion 6 is a second vertical line provided on the side wall of the cup body.

[0038] In this embodiment, scales are provided on the outer side of the cup body 1 .

[0039] During specific use, the dual-purpose oil cup is connected to the lubricating oil filling port of the cock or stroke by means of the external thread 7 provided on the outer wall of the oil outlet pipe 4. While the lubricating oil is being filled into the cock or stroke by pressure injection, the lubricating oil can also be filled into the cup body 1. After the external pressure injection equipment is removed, the one-way valve in the oil filling hole is used to ensure that the lubricating oil inside the cup body 1 does not overflow. During the inspection process of the operator, the cup cover 2 can be rotated by the force applying part to inject the lubricating oil stored in the cup body 1. The dual-purpose oil cup provided by the utility model is used, and the external thread 7 provided on the outer wall of the oil outlet pipe 4 is screwed and installed at the lubricating oil filling port of the cock or stroke. In both oil filling methods, there is no need to remove the oil cup, which greatly improves the operating efficiency and reduces the labor burden of the operator.

[0040] At the same time, the first force applying part 5 and the second force applying part 6 are provided, thereby improving the efficiency of the operator in rotating the cup cover 2 or the cup body 1 during the inspection process.

[0041] Since the injection operation requires a certain amount of pressure, the oil cup needs to have a certain pressure-bearing capacity. It is not convenient to replace its material with a transparent material or set a transparent viewing window on the cup body 1. By marking scales on the outside of the cup body 1, the operator can know the advancement distance of the cup cover 2 according to the scales, and quickly judge the degree to which the cup cover 2 is screwed into the side of the cup body 1, so as to know the remaining lubricating oil in the cup body 1. When the screwing distance of the cup cover 2 reaches a certain amount, the operator can perform the oil replenishing operation in time.

[0042] Example 2:

[0043] A dual-purpose oil cup, such as Figure 1 As shown, the difference from Example 1 is that the first force applying part 5 is a first nut fixed to the top of the cup cover 2, and the second force applying part 6 is a second nut fixed to the lower end of the cup body 1;

[0044] The first nut is sleeved on the outside of the oil filling pipe 3 , and the second nut is sleeved on the outside of the oil outlet pipe 4 .

[0045] Example 3:

[0046] An oil replenishing device, such as Figure 2 As shown, it includes an oil replenishment pipeline and two dual-purpose oil cups provided in Example 2.

[0047] In the dual-purpose oil cup, the oil filling pipe 3 is a quick connector male.

[0048] The flow direction of the oil supply pipeline includes the oil supply main pipe 11, the tee 12, the oil supply branch pipe 13 and the quick connector female 14.

[0049] The inlet end of the oil supply main pipe 11 is connected to an external injection device, and two oil supply branches 13 are provided on the oil supply pipeline.

[0050] The oil replenishment branch pipe 13 is provided with a flow control valve 15. Since the lubricating oil consumption rates of the two cocks may be different, if the two cocks are filled with lubricating oil at the same rate, one cock may be fully filled while the other cock is still short of oil. Therefore, the flow control valve 15 is provided to control the lubricating oil filling rate to ensure that both cocks can be filled at the same time.

[0051] In this embodiment, the flow control valve is a K12-12 hose ball valve produced by Jiangsu Baisuyuan Plastic Industry Co., Ltd., and other types of flow control valves can also be selected according to needs.
