Description
Technical Field
The utility model relates to the technical field of hydrogen energy utilization, in particular to a pipe orifice test plugging tool for hydrogen equipment.
Background
Along with the development of chemical industry, hydrogen equipment is increasingly applied to the field of hydrogen transportation and distribution, and in consideration of leakage, a flange-free field welding connection mode is adopted for the pipe orifice of some hydrogen equipment, when the equipment needs a hydraulic test in a manufacturing unit, the pipe orifice is required to be plugged, and at present, most of the equipment adopts a pipe orifice end part welding blind plate, and the method of cutting the blind plate after the test and then re-machining a pipe orifice groove is more labor-consuming, and for large-scale equipment, the pipe orifice groove is difficult to re-machine.
While the relevant engineering technicians also contemplate some solutions. For example, chinese patent publication No. CN204729657U discloses a pull rod sealing type vacuumizing plugging tool, which comprises a pull rod, a main nut with an upper seal groove and a lower seal groove respectively arranged on the upper part and the lower part of the pull rod, an O-ring a for sealing between the upper part of the main nut and the pull rod, an upper press ring for pressing the O-ring a, an upper nut for fixing the upper press ring, an O-ring B for sealing between the lower part of the main nut and the pull rod, a lower press ring for pressing the O-ring B, a lower nut for fixing the lower press ring, a valve body provided with an evacuation port, an O-ring C for sealing between the main nut and the valve body, a locking press ring for sealing between a vacuum nozzle on a workpiece and the valve body, a locking nut for fixing the locking press ring, and a vacuum plug fixed at the lower end of the pull rod, wherein the O-ring a and the O-ring B are respectively positioned in the upper seal groove and the lower seal groove of the main nut, the upper nut is fixed at the upper part of the main nut through the upper nut, the lower press ring B is pressed against the O-ring B, the lower press ring is fixed at the upper part of the main nut through the upper nut, the O-ring is fixed at the lower end of the main nut is pressed against the lower end of the main nut through the upper nut, the O-ring is fixed at the lower end of the main nut is pressed against the valve body through the lower seal ring, and the valve body is positioned at the lower end of the sealing cap, and the sealing cap is matched with the valve body through the sealing cap. Therefore, the technical scheme realizes the sealing of the vacuum container through the close matching of the plurality of O-shaped sealing rings, the sealing grooves and the nuts and the fixing action of the plurality of pressing rings and the plugs. However, the pull rod itself occupies a large space in this technical solution, and is not suitable for a container that needs to maintain a certain air pressure, such as a hydrogen filter.
Disclosure of Invention
