Description

Technical Field

[0001] The utility model belongs to a leak-blocking device, in particular to a novel leak-blocking device for a valve chamber pipeline casing. Background Art

[0002] At present, there is a serious water leakage in the valve well room along the oil pipeline from Changchun No. 2 Reservoir to the apron in summer and autumn. The main reason is that the waterproof function between the oil pipeline and the casing fails, causing surface water to flow into the valve well through the gap between the oil pipeline and the casing when the rainy season comes. At this time, it is necessary to arrange personnel to use submersible pumps for drainage from time to time, which not only increases the workload of the staff. At the same time, if the drainage is not timely, it will cause corrosion and leakage to the pipelines and valves in the well, reducing the service life of the pipelines and valves, and increasing the operating costs of the enterprise. If the valve is suddenly and completely damaged, production accidents such as oil leakage, bubbling, dripping and leakage will occur, which may easily cause environmental pollution, affect the fuel supply of flights, and cause serious consequences such as personnel poisoning.

[0003] At present, the method for dealing with water leakage at the pipe casing of the valve room well wall is mostly to use hard waterproofing by plugging from the inside of the pipe wall. This waterproofing method still has some disadvantages. First, it cannot guarantee that the gap between the oil pipeline and the casing can be 100% blocked. Second, it can only achieve a temporary blocking effect in the short term. Third, when using waterproof glue and other materials for sealing, due to the frost heave of the land in winter, the oil pipeline will undergo horizontal and vertical relative displacement in winter, which will cause the waterproof material to be damaged and fall off. It needs to be redone every year, which increases labor and economic costs. Summary of the invention

[0004] The utility model solves the deficiencies of the prior art and provides a novel leakage plugging device for a valve chamber pipeline casing.

[0005] The utility model discloses a novel leak-proof device for valve chamber pipeline casing, comprising a valve well, casings are respectively fixed in two opposite side walls in the valve well, oil pipelines are respectively arranged in the two casings, opposite ends of the two oil pipelines are fixedly connected to the valve through flanges, one end of a collecting chamber is fixedly connected to the inner wall of the valve well on the outer circumference of the casing through a flange, the other end of the collecting chamber is fixedly connected to the outer wall of the oil pipeline through a sealing ring, brackets are fixed in the collecting chamber and on the outer wall of the oil pipeline, a guide pipe is arranged at the upper end of the collecting chamber and a drain pipe is arranged at the bottom end, one end of the guide pipe is placed in the collecting chamber, and the other end is placed outside the valve well.

[0006] As a further improvement of the utility model, the bracket is composed of an inner ring, an outer ring and support rods evenly arranged between the inner ring and the outer ring, and the inner diameter of the inner ring is the same as the outer diameter of the oil pipeline.

A collecting chamber is provided at the oil pipeline and the casing to maintain water pressure balance and achieve leak-proofing. The collecting chamber is made of corrosion-resistant rubber material, which can maintain its softness at low temperatures. After long-term use and temperature and climate change tests, it has no cracking, aging and other phenomena. It is strong and durable, and can save labor and production costs. The provision of a guide pipe can automatically discharge the water in the collecting chamber to the outside of the valve well, thereby achieving the effect of automatic water collection and drainage. The overall design of the device ensures the normal service life of pipelines, valves and other equipment, reduces economic losses and safety hazards, and has strong practicality.
