A manifold with a leak-proof mechanism

Abstract

This utility model belongs to the field of oil well pipeline technology, and particularly relates to a manifold with an anti-leakage mechanism. It includes an oil pipe, an anti-leakage connection mechanism fixedly installed on the outer surface of the oil pipe, and an oil manifold monitoring mechanism fixedly installed on the outer surface of the anti-leakage connection mechanism. The anti-leakage connection mechanism includes a connecting flange, and a placement groove is formed on the inner surface of the connecting flange. A sealing ring is fixedly installed on the inner surface of the placement groove. In this manifold with an anti-leakage mechanism, high-pressure oil enters the sealing ring and continuously applies pressure, causing the sealing ring to adhere tightly to the placement groove, thereby sealing the gaps between the manifold sections. When a leak occurs at the manifold connection, the oil flows along the connecting flange under gravity to a second monitoring box, where an oil monitor detects the leak. Gas rises and reaches a first monitoring box, where it is detected by a natural gas monitor.

Description

Technical Field

[0001] This utility model relates to the field of oil well pipeline technology, and in particular to a manifold with a leak-proof mechanism. Background Technology

[0002] A manifold is an assembly of multiple pipes that converge, typically including gate valves, pipelines, pipe fittings, pressure gauges, and accessories such as electronic sensors and hydraulic control systems. There are various types of manifolds, each with its specific purpose. Manifolds are widely used in oil drilling and production, such as choke manifolds and hydraulic control systems, for controlling wellhead pressure and operations.

[0003] Oil well choke manifolds are crucial equipment in oil drilling and oil and gas extraction, primarily used to control well kicks and blowouts, as well as to implement oil and gas well pressure control technologies. However, the following problems arise in actual operation:

[0004] 1. Oil wells contain not only oil but also natural gas. As oil and natural gas flow through the manifold, natural gas will overflow from the connection points between the manifolds.

[0005] 2. Oil is typically transported under high pressure, which places stringent demands on the sealing performance of pipeline systems, especially at pipe joints. Current technologies often employ direct butt connections using internal or external threads, flanges, and clamps. These connections generally lack leakage detection mechanisms, making it impossible to monitor leakage at the joints in real time. This increases the uncertainty of safe oil transport and poses potential safety risks. Utility Model Content

[0006] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0007] Specifically, the technical problem to be solved by this utility model is to provide a manifold with a leak-proof mechanism to solve the technical problem that when oil flows in the manifold, the natural gas in the oil can easily leak out from the gaps in the manifold. At the same time, when natural gas and oil leak out at the manifold connection, it is not easy to detect. In daily use, the auxiliary protection device is easily bumped and shaken, which has an adverse effect on the internal oil well pipeline server.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] A manifold with a leak-proof mechanism includes an oil pipe, on the outer surface of which a leak-proof connection mechanism is fixedly installed, and on the outer surface of which an oil manifold monitoring mechanism is fixedly installed.

[0010] The leak-proof connection mechanism includes a connecting flange, the inner surface of which is fixedly connected to the outer surface of the oil pipe, and a placement groove is provided on the inner surface of the connecting flange, with a sealing ring fixedly installed on the inner surface of the placement groove.

[0011] As an improved technical solution, the leak-proof connection mechanism further includes a connecting compression plate, both sides of which are fixedly connected to the opposite side of the two connecting flanges.

[0012] As an improved technical solution, the leak-proof connection mechanism also includes a No. 1 bolt, the left end of which passes through the connecting flange and the connecting extrusion plate in sequence and extends to the outside of the connecting flange, and a No. 1 nut is installed on the outer surface thread of the No. 1 bolt.

[0013] As an improved technical solution, the oil manifold monitoring mechanism includes a protective cover, on the inner surface of which a sealing ring is fixedly installed, and the opposite sides of the two sealing rings are fixedly connected to the outer surface of the connecting flange.

[0014] As an improved technical solution, the oil manifold monitoring agency also includes a No. 1 monitoring box, the bottom of which is connected to the outer surface of the protective cover, and a natural gas monitor is fixedly installed in the inner cavity of the No. 1 monitoring box.

[0015] As an improved technical solution, the oil manifold monitoring agency also includes a second monitoring box, the top of which is connected to the outer surface of the protective cover, and an oil monitor is fixedly installed on the inner wall of the second monitoring box.

[0016] As an improved technical solution, the oil manifold monitoring mechanism also includes a No. 2 bolt, the outer surface of which is threadedly connected to the inner surface of the protective cover, and a No. 2 nut is installed on the outer surface thread of the No. 2 bolt.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are:

[0018] 1. This utility model improves upon the design of the oil manifold seal by using the oil pipe and connecting flange in conjunction with the placement groove and sealing ring, and by using the sealing ring and connecting extrusion plate in conjunction with the No. 1 bolt and No. 1 nut. This utilizes the pressure of the high-pressure oil in the oil pipe to squeeze the sealing ring outward, tightly adhering it to the inner wall of the connecting flange, thereby achieving a sealing effect and preventing high-pressure natural gas from being squeezed out from the gaps in the sealing ring.

[0019] 2. This utility model incorporates a design for real-time monitoring of oil and natural gas leaks in the manifold. Through the coordinated use of the oil pipe and connecting flange with the protective cover and sealing ring, the protective cover and No. 2 bolt with No. 2 nut with No. 1 monitoring box, and the No. 1 monitoring box and natural gas monitor working in conjunction with the No. 2 monitoring box and oil monitor, leaks in the oil manifold can be quickly detected, improving the safety and stability during transport.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown in the figure, this embodiment provides a manifold with a leak-proof mechanism. The manifold with the leak-proof mechanism includes an oil pipe 1, a leak-proof connection mechanism 2 is fixedly installed on the outer surface of the oil pipe 1, and an oil manifold monitoring mechanism 3 is fixedly installed on the outer surface of the leak-proof connection mechanism 2.

[0032] The leak-proof connection mechanism 2 includes a connecting flange 21, the inner surface of the connecting flange 21 is fixedly connected to the outer surface of the oil pipe 1, and a placement groove 22 is provided on the inner surface of the connecting flange 21. A sealing ring 23 is fixedly installed on the inner surface of the placement groove 22.

[0033] The sealing ring 23 is a special-shaped ring with a concave interior, which allows high-pressure oil to collect inside and continuously apply pressure to the sealing ring 23 to achieve a sealing effect.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, the leak-proof connection mechanism 2 also includes a connecting compression plate 24, both sides of which are fixedly connected to the opposite side of the two connecting flanges 21.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, the leak-proof connection mechanism 2 also includes a first bolt 25. The left end of the first bolt 25 passes through the connecting flange 21 and the connecting extrusion plate 24 in sequence and extends to the outside of the connecting flange 21. A first nut 26 is threaded on the outer surface of the first bolt 25.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, the oil manifold monitoring device 3 includes a protective cover 31, and a sealing ring 32 is fixedly installed on the inner surface of the protective cover 31. The opposite sides of the two sealing rings 32 are fixedly connected to the outer surface of the connecting flange 21.

[0037] like Figure 1 , Figure 2 and Figure 4 As shown, the oil manifold monitoring agency 3 also includes a first monitoring box 33. The bottom of the first monitoring box 33 is connected to the outer surface of the protective cover 31, and a natural gas monitor 34 is fixedly installed in the inner cavity of the first monitoring box 33.

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, the oil manifold monitoring agency 3 also includes a second monitoring box 35. The top of the second monitoring box 35 is connected to the outer surface of the protective cover 31, and an oil monitor 36 is fixedly installed on the inner wall of the second monitoring box 35.

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, the oil manifold monitoring device 3 also includes a No. 2 bolt 37, the outer surface of which is threaded to the inner surface of the protective cover 31, and a No. 2 nut 38 is installed on the outer surface of the No. 2 bolt 37.

[0040] In use, the operator first places the sealing ring 23 into the placement groove 22 inside the connecting flange 21, then covers it with the connecting compression piece 24. Next, the operator connects the two oil pipelines 1 and secures the connecting flanges 21 of the two oil pipelines 1 together with bolt 25 and nut 26. Then, the protective cover 31 is placed over the connection of the connecting flange 21 and connected with nut 38 and bolt 37 to secure the protective cover 31. Oil flows within the oil pipelines 1, and high-pressure oil enters the sealing ring 23, continuously applying pressure to it, causing the sealing ring 23 to adhere tightly to the placement groove 22, thus sealing the gap between the pipes. When a leak occurs at the pipe connection, the oil will flow along the connecting flange 21 under gravity to the second monitoring box 35, where the oil detector 36 detects the oil leak. The gas will rise and reach the first monitoring box 33, where it will be detected by the natural gas detector 34.
