[0002] A gas well sluice jumper is a device connected in parallel with the main shutoff valve to control the gas pressure in the operating area. Traditional jumpers are typically fabricated on-site based on specific operating scenarios and connected using steel pipes and flanges. These devices are not only non-reusable, resulting in a waste of resources, but are also time-consuming and labor-intensive to operate, impacting work efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a full range of gas gate well jumper devices and use methods. The jumper device has the advantages of simple structure, easy use, good versatility and strong practicality; the use method has the advantages of simple process and high work efficiency.

[0004] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a full-type jumper device for a gas gate well, including a steel pipe and a jumper front valve, a jumper main valve and a jumper rear valve arranged on the steel pipe in sequence, and hoses are connected to both ends of the steel pipe respectively. A pressure gauge is provided on the steel pipe between the jumper main valve and the jumper rear valve, and a bleed pipe is connected to the steel pipe between the pressure gauge and the jumper rear valve, and a control valve is provided on the bleed pipe.

[0005] Furthermore, the present invention provides a full-type jumper device for a gas gate well, wherein the jumper main valve is an electrically controlled pressure regulating valve, the jumper front valve, jumper rear valve and control valve are manual stop valves, and the hose is a metal pipe.

[0006] Furthermore, the present invention provides a full-type jumper device for a gas gate well, wherein the end of the hose is provided with a thread and a quick connector.

[0007] Based on the same concept, the present invention also provides a method for using the above-mentioned jumper device, comprising the following steps:

[0008] S1. When a gas pipeline needs emergency repair or line cutting and rerouting, connect the jumper device to the gas pipeline of the upstream gate well in the operation area. The hoses at both ends of the steel pipe are connected to the relief valves on both sides of the gate well main valve.

[0009] S2. Close the main shut-off valve of the gate well, open the vent valve, the front crossover valve, and the rear crossover valve, and then control the air pressure through the main crossover valve.

[0010] Furthermore, the present invention provides a method for using the jumper device, further comprising the following steps:

[0011] S3. When it is necessary to release gas from the gas pipeline in the working area, close the release valve in front of the main shut-off valve of the gate well, the front valve of the jumper and the main jumper valve, and open the control valve.

[0012] Compared with the prior art, the present invention provides a full-type gas gate well jumper device and a method of use thereof, which have the following advantages: the present invention provides a steel pipe and a jumper front valve, a jumper main valve and a jumper rear valve sequentially provided on the steel pipe, so that the two ends of the steel pipe are connected to hoses respectively, a pressure gauge is provided on the steel pipe between the jumper main valve and the jumper rear valve, the steel pipe between the pressure gauge and the jumper rear valve is connected to a bleed pipe, and a control valve is provided on the bleed pipe, thereby forming a full-type gas gate well jumper device with a simple structure, convenient use, good versatility and strong practicality. In actual application, when a gas pipeline needs emergency repair or line cutting and modification, the jumper device is connected to the gas pipeline of the gate well upstream of the operation area (the hoses at both ends of the steel pipe are connected to the bleed valves on both sides of the gate well main shut-off valve). After closing the gate well main shut-off valve and opening the bleed valve, the jumper front valve and the jumper rear valve, the gas pressure flowing to the operation can be accurately controlled through the jumper main valve. Compared with existing technologies, this invention eliminates spatial limitations by using a hose to connect the relief valve in the gate well. It is applicable to various types of gate wells, such as well chambers and directly buried wells, and is not restricted by the shape or depth of the gate well. By providing a threaded connection and a quick connector at the end of the hose, the connection operation is simplified and work efficiency is improved. The device is compact, lightweight, and easy to carry. A pressure gauge allows for intuitive monitoring of the gas pipeline pressure in the operating area, improving control convenience. The method for using the jumper device provided by this invention offers the advantages of a simple process and high work efficiency.

[0013] The following is a further detailed description of a full-type gas gate well jumper device and its use method of the present invention in conjunction with the specific embodiments shown in the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 The present invention is a schematic structural diagram of a full-type gas gate well jumper device. DETAILED DESCRIPTION

[0015] First of all, it should be noted that the directional words such as up, down, left, right, front and back mentioned in the present invention are only described according to the drawings for the convenience of understanding, and are not intended to limit the technical solution and scope of protection of the present invention.

[0016] like Figure 1The first embodiment of a full-scale gas lock well jumper device according to the present invention comprises a steel pipe 1 and, sequentially mounted on the steel pipe 1, a pre-jump valve 2, a main jumper valve 3, and a post-jump valve 4. Flexible hoses 5 are connected to each end of the steel pipe 1. A pressure gauge 6 is installed on the steel pipe 1 between the main jumper valve 3 and the post-jump valve 4. A bleed pipe 7 is connected to the steel pipe 1 between the pressure gauge 6 and the post-jump valve 4. A control valve 8 is also installed on the bleed pipe 7.

[0017] The above configuration creates a simple, easy-to-use, versatile, and practical gas sluice-well jumper device. In practical applications, when a gas pipeline requires emergency repair or line diversion, the jumper device is connected to the gas pipeline 100 of the upstream sluice-well in the operation area (the flexible pipes 5 at both ends of the steel pipe 1 are connected to the relief valves 300 on both sides of the sluice-well main shut-off valve 200). After closing the sluice-well main shut-off valve 200 and opening the relief valve 300, the front- and rear-crossover valves 2, and 4, the gas pressure flowing to the operation can be precisely controlled through the main crossover valve 3. Compared with the prior art, the present invention eliminates space limitations by using a hose 5 to connect the relief valve 300 in the gate well. It is applicable to various types of gate wells such as well chambers and directly buried wells, and is not restricted by the shape and depth of the gate well. Threads and quick connectors can be provided at the end of the hose 5 to improve the simplicity of connection operation and work efficiency. The hose is small, light, and easy to carry. The gas pipeline pressure in the operating area can be intuitively understood based on the pressure gauge 6, thereby improving control convenience.

[0018] In practical applications, the present invention utilizes an electrically controlled pressure-regulating valve for the main jumper valve 3, enabling automatic control based on the gas pressure in the operating area. Manual shut-off valves are used for the pre-jump valve 2, post-jump valve 4, and control valve 8, reducing costs and improving operational convenience, safety, and reliability. To ensure structural stability, the present invention typically utilizes a metal tube for the hose 5. Threaded threads and quick connectors are provided at the ends of the hose 5 for quick connection, making it suitable for emergency repair scenarios.

[0019] Based on the same concept, the present invention also provides a method for using a full-type jumper device for a gas well, which specifically includes the following steps:

[0020] S1. When a gas pipeline needs emergency repair or line cutting and modification, the jumper device is connected to the gas pipeline 100 of the upstream gate well in the operation area, wherein the hoses 5 at both ends of the steel pipe 1 are connected to the relief valves 300 on both sides of the gate well main shut-off valve 200.

[0021] S2. Close the main intercept valve 200 of the gate well, open the diffuser valve 300, the cross-connect front valve 2, and the cross-connect rear valve 4, and then control the air pressure through the cross-connect main valve 3.

[0022] S3, when the gas in the work area gas pipeline needs to be released, the release valve 300 in front of the main gate valve 200, the cross-connection front valve 2 and the cross-connection main valve 3 are closed, and the control valve 8 is opened.

[0023] The use method of the cross-connection device has the advantages of simple flow and high work efficiency.

[0024] The above embodiments only describe the preferred embodiments of the present application, and do not limit the protection scope of the present application. Various modifications made by those skilled in the art according to the technical solutions of the present application should fall within the protection scope determined by the claims of the present application.
