Description

Technical Field

[0001] This utility model relates to the field of oil well production valve technology, specifically to an oil well production valve for reversing and depressurizing. Background Technology

[0002] Production wells are conventionally defined as wells drilled specifically for the extraction of oil and natural gas, or wells converted from production wells to produce oil or gas. However, in a broader sense, production wells also include water injection wells, gas injection wells, and observation wells drilled for the development of oil and gas fields. Currently, in the oil and gas production process, a check valve is installed in the casing gas discharge process connected to the oil wellhead to control the medium transported by the external pipeline. However, existing oil well production valves do not have an automatic multi-stage pressure relief function when the internal pressure of gas and liquid suddenly increases. If the pressure suddenly increases during gas and liquid flow, and the operator is slow to detect and deal with it, the pipeline may rupture due to excessive internal pressure, causing internal gas and liquid leakage. At the same time, existing oil wellhead production valves are easily opened or closed accidentally by touching the pilot valve, which can affect production and reduce the effectiveness of the oil wellhead production valves. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a reversing pressure relief oil well production valve. This addresses the issue that existing oil well production valves, as mentioned in the background, lack an automatic multi-stage pressure relief function when gas and liquid pressure suddenly increases. Furthermore, in cases of sudden pressure increases during gas and liquid flow, if operators are slow to detect and address the problem promptly, the pipeline may rupture due to excessive internal pressure, leading to internal gas and liquid leakage. Additionally, existing oil wellhead production valves are easily opened or closed accidentally by touching the pilot valve, thus affecting production and reducing their effectiveness.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a reversing pressure relief oil well production valve, including a locking and limiting structure, wherein the locking and limiting structure is provided with a reversing pressure relief structure inside;

[0005] The locking and limiting structure includes a valve body with inlaid flange tubes at both ends, and a handwheel is rotatably installed on the top of the valve body. At the same time, a grooved column is welded and fixedly installed on one side of the top of the valve body.

[0006] Both the grooved post and the handwheel have through holes that connect them, and a limit rod is placed inside the through hole.

[0007] By adopting the above technical solution, the limiting rod is set to achieve the function of limiting insertion.

[0008] Preferably, a connecting pipe with a hollow internal structure is embedded and installed above the flange pipe, and a conveying pipe is embedded and installed on the surface of the connecting pipe.

[0009] By adopting the above technical solution, the conveying pipes are installed to achieve the function of continuous conveying.

[0010] Preferably, the reversing pressure relief structure includes a connecting plate with a through-hole, and a sliding hole is through-hole in the center of the connecting plate, with a connecting rod sliding in the sliding hole.

[0011] By adopting the above technical solution, the connecting rods are designed to provide a squeezing and sliding function.

[0012] Preferably, a connecting spring is installed through the connecting rod, and one end of the connecting spring is fixedly installed to the upper side of the connecting rod through a connecting block, while the other end of the connecting spring is fixedly installed to the upper part of the connecting plate.

[0013] By adopting the above technical solution, the connecting springs are used to fix both ends.

[0014] Preferably, an extrusion block is fixedly installed inside the vent hole, an installation plate is fixedly installed above the connecting rod, and a hollow tube is fixedly installed above the installation plate. At the same time, a through-hole groove is installed above and directly in front of the hollow tube, and a spring plate is fixedly installed inside the through-hole groove.

[0015] By adopting the above technical solution, the spring sheet is designed to achieve the function of squeezing and relieving pressure.

[0016] Preferably, the connecting plate is fixedly installed inside the lower part of the connecting pipe, and a single connecting plate is locked inside the connecting pipe.

[0017] By adopting the above technical solution, the connecting plate is used to open and fix the device.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this reversing and depressurizing oil well production valve,

[0019] (1) This case solves the problem that existing oil wellhead production valves are easily opened or closed accidentally when touched during use, which affects production and reduces the effectiveness of the oil wellhead production valves by setting a locking limit structure. When the handwheel needs to be used, the magnet is brought close to the groove column to attract the limit rod above the groove column, which makes it convenient to rotate and adjust the handwheel.

[0020] (2) By setting up a reversing pressure relief structure, the existing oil well production valve does not have an automatic adjustment multi-stage pressure relief function when the gas and liquid internal pressure suddenly increases. When the pressure increases suddenly during gas and liquid flow, if the staff finds out and deals with it in time, it is easy to cause the pipeline to rupture due to excessive internal pressure, resulting in internal gas and liquid leakage. When the pressure on one side of the valve body is high, the gas and liquid internal pressure pushes the installation plate and drives the connecting rod to move under force. At this time, the gas and liquid internal pressure is conveniently transported through the delivery pipe to the flange pipe on the other side of the valve body for gas and liquid internal pressure relief. At the same time, when the gas and liquid internal pressure on the other side of the valve body is high, the gas and liquid internal pressure pushes the installation plate to move in the opposite direction. At this time, the extrusion block extrudes the spring plate to relieve the gas and liquid internal pressure inside the hollow pipe and transport it to the flange pipe on one side of the valve body for pressure relief.

[0021] (3) The connecting pipe and the delivery pipe set in the locking and limiting structure facilitate the reversal and pressure relief of gas and liquid internal pressure, thereby avoiding the need for pressure relief in only one direction. Attached Figure Description

[0029] 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.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a reversing pressure relief oil well production valve, such as... Figure 1 , Figure 2 and Figure 3 As shown, it includes a locking and limiting structure 1. The locking and limiting structure 1 includes a valve body 101 with inlaid flange tubes 102 at both ends, and a handwheel 103 is rotatably installed on the top of the valve body 101. Meanwhile, a grooved column 104 is welded and fixedly installed on one side of the top of the valve body 101. Both the grooved column 104 and the handwheel 103 are provided with through holes 105, and a limiting rod 106 is placed inside the through hole 105.

[0031] The valve body 101 and handwheel 103 are both designed using existing technical components. Using existing technical components effectively serves the functions of rotation adjustment and installation connection and conveying. The limit rod 106 is made of a metal material that can be attracted by a magnet. Using a metal material that can be attracted by a magnet effectively facilitates the attraction and lifting of the limit rod 106 by a magnet. At the same time, the handwheel 103 avoids having only one through hole 105. Therefore, when limiting the handwheel 103, the through hole 105 on the handwheel 103 needs to be rotated to match the through hole 105 on the groove post 104 in order to limit the rotation of the handwheel 103.

[0032] Furthermore, in the above scheme, a connecting pipe 107 with a hollow internal structure is embedded and installed above the flange pipe 102, and a conveying pipe 108 is embedded and installed on the surface of the connecting pipe 107.

[0033] The aforementioned components also utilize existing technology, which effectively facilitates pressure relief at both ends.

[0034] like Figure 4 , Figure 5 and Figure 6 As shown, the locking and limiting structure 1 is provided with a reversing pressure relief structure 2 inside. The reversing pressure relief structure 2 includes a connecting plate 201 with a through-hole 202, and a sliding hole 203 is provided in the center of the connecting plate 201. A connecting rod 204 slides in the sliding hole 203.

[0035] The ventilation holes 202 are provided in multiple ways, which can effectively facilitate the dispersion and pressure relief of the pressure.

[0036] Furthermore, in the above scheme, a connecting spring 205 is installed through the connecting rod 204, and one end of the connecting spring 205 is fixedly installed on the upper side of the connecting rod 204 through a connecting block, while the other end of the connecting spring 205 is fixedly installed on the upper part of the connecting plate 201.

[0037] Among them, the above-mentioned components constitute an elastic adjustment structure. The elastic adjustment structure constituted by the above-mentioned components can effectively change the lifting range distance of the mounting plate 207, thereby facilitating the pressure reversal and pressure relief.

[0038] Furthermore, in the above scheme, an extrusion block 206 is fixedly installed inside the vent 202, an installation plate 207 is fixedly installed above the connecting rod 204, and a hollow tube 208 is fixedly installed above the installation plate 207. At the same time, a through-hole groove 209 is installed above and directly in front of the hollow tube 208, and a spring plate 2010 is fixedly installed inside the through-hole groove 209. The connecting plate 201 is fixedly installed inside the lower part of the connecting tube 107, and a single connecting plate 201 is locked inside the connecting tube 107.

[0039] The number of hollow tubes 208 is set to the same number as the number of vent holes 202. When the two are set to the same number, they can effectively match and connect.

[0040] In the above scheme, when it is necessary to rotate the handwheel 103, the magnet is brought close to the groove post 104 and then moved. The groove post 104 attracts the limiting rod 106 and moves it upward along the through hole 105. At this time, the limiting rod 106 gradually separates from the handwheel 103 and the groove post 104, making it convenient for the operator to manually hold the handwheel 103 for rotation and adjustment. When the gas-liquid pressure inside the valve body 101 is high, the gas-liquid pressure pushes the mounting plate 207 through the vent hole 202, causing the connecting rod 204 and the connecting spring 205 to move upward along the connecting pipe 107. Hydraulic pressure is transported through the delivery pipe 108 to the inside of another flange pipe 102 for rapid pressure relief. When the gas-liquid pressure inside the other flange pipe 102 is too high, the gas-liquid pressure squeezes the mounting plate 207. At this time, the gas-liquid pressure is transported through the through hole groove 209 to the inside of the hollow pipe 208. Then, the mounting plate 207 gradually moves downward, causing the hollow pipe 208 to pass through the vent hole 202. At this time, the squeezing block 206 inside the vent hole 202 is squeezed against the spring plate 2010. At this time, the gas-liquid pressure inside the hollow pipe 208 is also transported through the delivery pipe 108 to the inside of the flange pipe 102 for pressure relief.
