Description

Technical Field

[0001] This utility model relates to the field of oil production pipeline equipment technology, and in particular to an oil production pipeline cross that can detect pressure. Background Technology

[0002] A primary function of a four-way connector is to distribute or switch fluids. During oil extraction, it's necessary to direct extracted oil, natural gas, or water to different pipelines, storage tanks, or treatment facilities. A four-way connector allows for flexible connection and flow direction adjustment of multiple pipelines through four interfaces, ensuring fluid distribution as needed. However, a pipeline four-way connector has four pipes, each equipped with a corresponding on / off valve, typically for precise control of fluid flow. In emergency situations or system anomalies, such as fires, leaks, or equipment malfunctions, immediate shutdown and closure of all valves are usually required to prevent the accident from escalating. Traditional four-way valves can only be operated one at a time in these dangerous situations, unable to adjust multiple valves simultaneously. This means operators must check and operate multiple valves one by one, which is inefficient, especially in emergencies, as operating them individually wastes valuable time and increases risk. Utility Model Content

[0003] The purpose of this invention is to address the problem that traditional four-way valves can only be operated one by one in dangerous situations, and cannot adjust multiple valves at the same time. Operating them one by one wastes valuable time and increases risks. This invention proposes a pressure-detectable four-way valve for oil production pipelines.

[0004] The technical solution of this utility model is as follows: a pressure-detecting oil pipeline four-way, including a pipeline four-way body and a pressure gauge installed on one end of the pipeline four-way body, and further including: multiple end pipes installed on the ends of the pipeline four-way body, each end pipe being provided with a switch valve; a rotating mechanism fixedly installed in the middle of the pipeline four-way body; and a spring-loaded mechanism disposed on the switch valve, which causes the switch valve to open and close in conjunction with the rotation mechanism.

[0005] Optionally, the locking mechanism includes a secondary gear sleeve fitted onto the switch valve. The inner wall of the secondary gear sleeve has multiple slots arranged in a circumferential array. The outer wall of the switch valve is fixedly connected to a locking block that engages with the slots. The secondary gear sleeve has a first sliding groove and a second sliding groove that communicate with each other. A central block is fixedly connected to the middle of the pipeline four-way body. The outer wall of the central block is fixedly connected to multiple support plates corresponding to the switch valve. The end of each support plate away from the central block is fixedly connected to a sliding rod that is slidably connected to the first sliding groove. The end of each sliding rod away from the support plate is fixedly connected to a sliding ball block that engages with the second sliding groove.

[0006] Optionally, each end of the support plate away from the central block is fixedly connected with a return spring that is sleeved with the sliding ball block and the sliding rod, and the top end of each return spring is fixedly connected with a retaining ring that abuts against the secondary gear sleeve.

[0007] Optionally, the rotating mechanism includes a rotating support block fixedly connected to the center of the central block, and a main gear rotatably connected to the rotating support block and meshing with multiple secondary gear sleeves.

[0008] Optionally, a pair of handles are fixedly connected to the main gear.

[0009] Optionally, a pinch block is fixedly connected to the end of the switch valve that is away from the end pipe.

[0010] Optionally, a spiral connector is fixedly connected to the end of the end tube away from the main body of the pipeline.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] This invention utilizes the coordination of end pipes, switching valves, a rotating mechanism, and a locking mechanism. In emergency situations, by pressing the secondary gear sleeve in advance and then rotating the main gear, multiple switching valves on the pipeline four-way body can be simultaneously closed or opened. This not only enables rapid response to emergencies, shortening processing time and preventing the escalation of accidents, but is also crucial in reducing potential hazards. Furthermore, it reduces the risk of other parts of the system being affected, thereby ensuring the safety of the entire system. Attached Figure Description

[0024] Example

[0025] like Figures 1 to 4 As shown, this utility model proposes a pressure-detecting oil pipeline four-way connector, including a pipeline four-way connector body 1 and a pressure gauge 2 installed at one end of the pipeline four-way connector body 1. The pressure gauge 2 is an instrument used to measure and monitor the pressure in the pipeline system. In a four-way pipeline system, the pressure gauge 2 plays a particularly important role because such systems often involve flow in multiple pipes and directions, and pressure changes can affect the safety and operational efficiency of the entire system. The pressure gauge 2 helps the operator understand the current pressure status in the pipeline so that flow can be adjusted in a timely manner or measures can be taken to prevent equipment damage or leakage caused by abnormal pressure. It also includes: multiple end pipes 3, each end pipe 3 having a fixed spiral connector 33 at its end furthest from the pipeline four-way connector body 1, which connects the pipeline four-way connector body 1 to the oil pipeline. Each end pipe 3 is equipped with a switch valve 31 installed at the end of the pipeline four-way connector body 1, which controls whether oil can pass through the end pipe 3. Each end of the switch valve 31, away from the end pipe 3, is fixedly connected to a pinch block 34. The pinch block 34 serves as a force point for individually closing or opening the switch valve 31, making it easy and effortless to close or open the switch valve 31 individually. A rotating mechanism is fixedly installed in the middle of the pipeline four-way body 1. A spring-loaded mechanism is set on the switch valve 31, and the switch valve 31 is linked to open and close when the rotating mechanism is activated. By simultaneously opening and closing multiple switch valves 31, the system can ensure a rapid and accurate response to emergencies, avoiding human error.

[0026] Furthermore, the locking mechanism includes a secondary gear sleeve 5 fitted onto the switch valve 31. The inner wall of the secondary gear sleeve 5 has multiple slots 51 arranged in a circular array. A locking block 32, which engages with the slots 51, is fixedly connected to the outer wall of the switch valve 31. The secondary gear sleeve 5 has a first sliding groove 52 and a second sliding groove 53 that communicate with each other. The second sliding groove 53 is lubricated to facilitate smoother sliding of the sliding ball block 43 within it. A central block 4 is fixedly connected to the middle of the pipeline four-way body 1. Multiple support plates 41, corresponding to the switch valve 31, are fixedly connected to the outer wall of the central block 4. Each support plate 41, away from the central block 4, has a sliding rod 47 that slides through the first sliding groove 52. The end of the sliding rod 47 away from the support plate 41 is fixedly connected to a sliding ball block 43 that engages with the second sliding groove 53.

[0027] Each end of the support plate 41 away from the center block 4 is fixedly connected to a return spring 44, which is sleeved with the sliding ball block 43 and the sliding rod 47. The return spring 44 causes the secondary gear sleeve 5, which is not stuck, to automatically return to its original position, which is the state in which the groove 51 inside the secondary gear sleeve 5 is not stuck by the locking block 32. The top of each return spring 44 is fixedly connected to a retaining ring 48 that abuts against the secondary gear sleeve 5.

[0028] Furthermore, the rotating mechanism includes a rotating support block 45 fixedly connected to the center of the central block 4. A main gear 42 that meshes with multiple secondary gear sleeves 5 is rotatably connected to the rotating support block 45. A pair of handles 46 are fixedly connected to the main gear 42, and the handles 46 make it easier and less strenuous to rotate the main gear 42.

[0029] In this embodiment, a pressure-detectable four-way valve in the oil production pipeline is required. When the switching valves 31 on the end pipe 3 are closed simultaneously, it is only necessary to press the secondary gear sleeves 5 one by one in advance, so that the secondary gear sleeves 5 slide along the switching valves 31 towards the support plate 41 until the sliding ball block 43 passes through the first slide groove 52 and is locked into the second slide groove 53, and the sliding rod 47 is also locked in the first slide groove 52. At this time, the multiple secondary gear sleeves 5 drive the locking grooves 51 inside to lock the locking blocks 32 on the switching valves 31. At the same time, the outer walls of the multiple switching valves 31 are meshed with the main gear 42 on the central block 4. Therefore, by manually holding the handle 46 on the main gear 42 and turning it, the main gear 42 can drive the secondary gear sleeves 5 to rotate. After rotation, the secondary gear sleeves 5 drive the switching valves 31 to rotate through the locking blocks 32 locked in their internal locking grooves 51. Thus, the main gear 42 can rotate in different directions, thereby opening or closing the switching valves 31, which is quick and easy to operate. When a single switch valve 31 needs to be switched, simply do not press the secondary gear sleeve 5 on the switch valve 31. At this time, the slot 51 and the block 32 on the switch valve 31 are not locked. The switch valve 31 can be switched on and off by rotating the corresponding pinch block 34 on the switch valve 31.
