Description

Technical Field

[0001] The utility model belongs to the technical field of oil filling of diaphragm valves of special equipment for nuclear engineering, and in particular relates to an automatic quantitative filling device for lubricating oil of valves of special equipment. Background Art

[0002] The original technology is that the special lubricating oil is first dispensed into an open beaker, a quantitative lubricating oil (1 ml) is drawn from the beaker using a universal syringe, and then the lubricating oil is injected from the injection hole of the diaphragm valve, and the injection hole of the diaphragm valve matches the syringe needle.

[0003] However, in actual use in this industry, this method is less efficient. This construction process can only be carried out on site after the installation of special equipment is completed. Due to the constraints of on-site conditions, it is impossible to use modern tools to complete the oiling. It can only be done manually once, that is, one extraction and one injection. In addition, the viscosity of special lubricating oil is large, and the suction speed of the general syringe barrel is slow, so the oiling time of each device is relatively long. At the same time, when manually absorbing the lubricating oil, there may be insufficient exhaust of the syringe or insufficient suction time, resulting in a certain negative deviation in the quantitative amount. The quality requirements of the oiling project must not have insufficient oiling. During the quality inspection, it was found that a large number of diaphragm valves needed to be refilled with oil, and the rework rate was high.

[0004] The existing oil injection technology has many shortcomings in actual operation, such as:

[0005] (1) The viscosity of special lubricating oil is large, the manual suction speed of general syringe barrel is slow, the injection power is limited, and the oil filling time of each equipment is long. When the oil filling task of the valve of the special equipment for the project is large, the low oil filling efficiency affects the progress of the project.

[0006] (2) When manually sucking lubricating oil, there may be insufficient exhaust of the syringe or insufficient suction time, resulting in a certain negative deviation in the quantitative (1ml), leading to insufficient oil filling. A large number of diaphragm valves need to be refilled with oil, resulting in a high rework rate and serious waste of manpower and working hours. Utility Model Content

[0007] The utility model solves the technical problem of providing an automatic quantitative filling device for special equipment valve lubricating oil, which is fast and convenient, can reduce the limitation of human operation factors, meet the short-term large-scale oil filling needs of the project, and slow down the aging speed of the diaphragm valve sealing gasket.

[0008] The technical solution adopted by this utility model:

[0009] A device for automatically quantitatively filling lubricating oil for valves of special equipment comprises a pressure vessel, an injection pusher, a pressure vessel handle, a pressurizing device, an outer sleeve of a syringe, and a liquid delivery pipeline. The pressure vessel is an ellipsoidal structure with a pressurizing device installed on the top thereof, and the pressurizing device is provided with a pressure vessel handle; the pressurizing device is connected to a liquid delivery pipeline, and the other end of the liquid delivery pipeline is connected to the side of the outer sleeve of the syringe; an injection pusher is provided at the end of the outer sleeve of the syringe.

[0010] The pressure vessel is provided with fully stirred lubricating oil.

[0011] Pressing the handle of the pressure container pressurizes the interior of the pressure container, so that the lubricating oil flows from the pressure container into the liquid transmission pipeline under the action of pressure, and finally into the outer sleeve of the syringe.

[0012] The outer sleeve of the syringe is provided with a filling scale which can display the filling amount of the syringe.

[0013] The injection pusher is connected to the interior of the outer sleeve of the syringe.

[0014] A syringe handle is fixedly mounted on the outer sleeve of the syringe, and the stroke of pushing the injection pusher to the syringe handle is to quantitatively add 1 ml of lubricating oil.

[0015] After completing one injection, the lubricating oil is automatically injected into the syringe through the liquid delivery pipe under pressure.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The utility model provides a special equipment valve lubricating oil automatic quantitative filling device, which can realize automatic oil replenishment and oil filling under the action of pressure by adjusting the pressure of the pressure container, significantly increasing the power of lubricating oil injection and the controllability of injection volume, reducing the negative deviation of oil injection volume, improving the efficiency of batch manual oil filling process, and ensuring the quality of oil filling process.

[0018] (2) The utility model provides a special equipment valve lubricating oil automatic quantitative filling device, which fully stirs the diaphragm valve oil and pours it into the modified pressure container, that is, the pressure container is used instead of the open beaker as the lubricating oil sub-packaging container, the pressure container outlet joint is modified, and a liquid transmission pipeline is connected between the outlet pipe head and the pressure container. After the connection is completed, the pressure of the container is adjusted, and after the syringe completes a quantitative injection (1ml), the lubricating oil is automatically injected into the syringe under pressure and the injection is completed, and the cycle is in sequence until the lubricating oil in the container is completely filled, thereby increasing the flow rate of the oil and ensuring sufficient oil absorption.

[0019] (3) The utility model provides a special equipment valve lubricating oil automatic quantitative filling device, which is modified by using a pressure vessel, is simple to manufacture, convenient to use and has low cost.

[0020] (4) The utility model provides a special equipment valve lubricating oil automatic quantitative filling device, which adjusts the pressure of the pressure container to form internal pressure in the delivery channel, and realizes automatic oil replenishment and oil injection under the action of pressure, thereby increasing the power and continuity of lubricating oil injection and significantly improving the speed of oil injection.

[0021] (5) The utility model provides a special equipment valve lubricating oil automatic quantitative filling device, which allows the syringe to fully absorb the lubricating oil under pressure, and there is no quantitative negative deviation. Only positive deviation may occur, that is, the amount of oil injection is slightly excessive. At this time, the excess trace amount of lubricating oil can be wiped off with a rag. Compared with the original general syringe oiling method, it effectively avoids the situation of insufficient oil injection due to insufficient syringe exhaust or insufficient suction time, which greatly reduces the rework rate.
