Abstract
Description
Technical Field
[0001] This utility model relates to the technical field, specifically to an interface for a skid-mounted three-phase separation metering device. Background Technology
[0002] The skid-mounted three-phase separation metering device is an integrated device that separates and meters oil, gas and water phases. It is mainly used for crude oil metering, natural gas metering and produced water treatment in the oil and gas field development process. It is usually designed to be modular and can be skid-mounted as a whole, which is convenient for installation, relocation and maintenance.
[0003] During operation, the three-phase separation metering device introduces oil, gas, and water into its interior. The introduction points are sealed using interfaces. The interfaces are typically connected via flanges or threads. Flanges require multiple screws for fixing, while threaded connections are prone to stripping during operation. Neither of these connection methods allows for quick connection, and both require wrapping with PTFE tape, which is inconvenient for operation. Utility Model Content
[0004] The purpose of this utility model is to provide a skid-mounted three-phase separation metering device interface to solve the problem mentioned in the background art that the interface position in the current market is not convenient for quick installation.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a skid-mounted three-phase separation metering device interface, including a connecting pipe, a sub-connector and a female connector, the sub-connector and the female connector are installed at the end of the connecting pipe, the sub-connector and the female connector are engaged and connected, and an air bladder is provided inside the sub-connector on the side near the female connector, the air bladder fills the gap between the sub-connector and the female connector.
[0006] Preferably, the female connector is threaded with a swivel ring on its outer side, and a limit rod is installed at an equal angle on the side of the swivel ring closest to the female connector.
[0007] Preferably, the female connector has through holes at equal angles, and a compression plate is installed on the side of the female connector near the male connector.
[0008] Preferably, a fixing ring is installed inside the sub-connector on the side near the female connector, and a sealing tube is installed on the fixing ring at equal angles. The sealing tube is connected to the airbag, and an insertion rod is engaged at the other end of the sealing tube. A piston is installed at the end of the insertion rod near the sealing tube, and a spring is installed between the piston and the sealing tube.
[0009] Preferably, the outer side of the piston is in contact with the inner wall of the sealing tube, the insertion rod and the limiting rod correspond one-to-one, and the distance from the end of the insertion rod protruding from the sealing tube is greater than the thickness of the female connector.
[0010] Preferably, the insertion rod has a notch, the limiting rod is inserted into the notch, and the compression plate is aligned with the airbag.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model is equipped with an airbag and a compression plate. After the male and female connectors are connected, the compression plate compresses the airbag. After the airbag is deformed by compression, it fills the gap between the male and female connectors, so that the interface of the three-phase separation metering device is sealed and gas and liquid are prevented from escaping from the gap, thus enabling rapid connection.
[0013] 2. This utility model is equipped with a rotating ring, a limiting rod, and an insert rod. The rotating ring rotates and moves to move the limiting rod to the notch position of the insert rod. Due to the cooperation between the insert rod and the limiting rod, the insert rod is limited, thereby connecting the male connector and the female connector. At the same time, it ensures the sealing of the interface position of the male connector and the female connector, and enables quick installation and disassembly of the male connector and the female connector.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-5 The present invention provides the following technical solution:
[0022] A skid-mounted three-phase separation metering device interface includes a connecting pipe 1, a sub-connector 2, and a female connector 3. The sub-connector 2 and the female connector 3 are installed at the ends of the connecting pipe 1 and are engaged and connected. An air bladder 9 is provided inside the sub-connector 2 on the side near the female connector 3. The air bladder 9 fills the gap between the sub-connector 2 and the female connector 3. The extrusion plate 8 is aligned with the air bladder 9.
[0023] During the process of connecting the male connector 2 and the female connector 3, the extrusion plate 8 comes into contact with the airbag 9 and the extrusion plate 8 extrudes the airbag 9. After the airbag 9 is extruded, some of the gas inside escapes and the other part of the gas remains inside the airbag 9. After the extrusion plate 8 extrudes and deforms the airbag 9, it fills the gap between the male connector 2 and the female connector 3. The airbag 9 fills the gap to achieve a seal between the male connector 2 and the female connector 3 and prevents the gas from leaking out.
[0024] The outer side of the female connector 3 is threaded with a swivel 6, and the swivel 6 is equipped with a limit rod 7 at an equal angle on the side close to the male connector 2. The insertion rod 4 corresponds to the limit rod 7 one by one. The distance from the end of the sealing tube 10 of the insertion rod 4 is greater than the thickness of the female connector 3. The insertion rod 4 is provided with a notch, and the limit rod 7 is inserted into the notch.
[0025] After the female connector 2 and the female connector 3 are connected, to ensure their stability, rotate the rotating ring 6 by hand. As the rotating ring 6 rotates, it moves, and the rotating ring 6 drives the limiting rod 7 to move synchronously until the limiting rod 7 is inserted into the notch on the insertion rod 4. The limiting rod 7 is used to limit the insertion rod 4, thereby allowing the insertion rod 4 to fix both the female connector 3 and the female connector 2, thus realizing the installation of the female connector 2 and the female connector 3.
[0026] The female connector 3 has a through hole 5 at an equal angle. A compression plate 8 is installed on the side of the female connector 3 near the male connector 2. A fixing ring 11 is installed inside the male connector 2 near the female connector 3, and a sealing tube 10 is installed on the fixing ring 11 at an equal angle. The sealing tube 10 is connected to the airbag 9. An insertion rod 4 is engaged at the other end of the sealing tube 10. A piston 12 is installed at the end of the insertion rod 4 near the sealing tube 10. A spring 13 is installed between the piston 12 and the sealing tube 10. The outer side of the piston 12 is in contact with the inner wall of the sealing tube 10.
[0027] When the airbag 9 is squeezed, some gas enters the sealing tube 10. The gas pushes the piston 12, causing the piston 12 to move closer to the through hole 5. The movement of the piston 12 drives the insertion rod 4 to move synchronously. When the male connector 2 and the female connector 3 stop moving relative to each other, the insertion rod 4 passes through the through hole 5. The end and notch of the insertion rod 4 are located outside the female connector 3, which facilitates other operations afterward.
[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
