Description

Technical Field

[0001] The invention relates to the technical field of storage tanks and separators in the process of crude oil gathering and transportation, and is a water-cut sight glass non-disassembly cleaning device. Background Art

[0002] At present, water-cut sight glasses are used in crude oil storage tanks and separators in oil fields. In the production process, water-cut sight glasses are mainly used to observe the discharge of water nozzles, so as to judge whether the medium in the crude oil storage tanks or separators meets the production needs. At present, the common water-cut sight glasses are annular glass plus top cover combination and arched glass cover. The bottoms of these two water-cut sight glasses are connected to the water nozzle flange to form a closed space to prevent the water nozzle from splashing and contacting the outside world during the discharge process. However, frequent water-cutting operations during production operations can easily cause the inner wall of the water-cut sight glass to become dirty, making it difficult to observe. Under low ambient temperature conditions, the water in the water-cut sight glass is seriously condensed, and the condensed water adheres to the entire inner wall of the water-cut sight glass, which seriously affects the operator's observation of the discharge of the water nozzle. This requires timely disassembly and cleaning of the water-cut sight glass. However, frequent disassembly and cleaning not only increases the workload but also easily causes environmental pollution. In addition, the disassembly process may also cause the rubber pad between the water-cutting sight glass and the pressure cover to break, which may damage the water-cutting sight glass. Summary of the invention

[0003] The present invention provides a disassembly-free cleaning device for a water-cutting sight glass, which overcomes the deficiencies of the above-mentioned prior art and can effectively solve the problems of high labor intensity, environmental pollution and high material loss in the disassembly and cleaning process of the prior water-cutting sight glass.
