Description

Technical Field

[0001] The utility model relates to the technical field of choke manifolds, in particular to a choke manifold with a buffer mechanism. Background Art

[0002] The choke manifold is one of the key equipment in the oil drilling process and is also an important component for safety accidents. During the closing process of the choke manifold, the liquid flowing inside has a corresponding impact force. When the liquid impact force is transmitted to the internal components of the choke manifold, the components will cause impact on the internal components of the choke manifold. If the impact is serious, it will cause a water hammer effect on the choke manifold. Utility Model Content

[0003] The purpose of the present utility model is to address the deficiencies of the prior art and provide a choke manifold with a buffer mechanism to solve the problem proposed in the above background technology that the liquid flowing inside the choke manifold during the closing process has a corresponding impact force. When the liquid impact force is transmitted to the internal components of the choke manifold, the components will cause impact on the internal components of the choke manifold. If the impact is serious, it will cause a water hammer effect on the choke manifold.

[0004] To achieve the above object, the present invention provides the following technical solutions: a choke manifold with a buffer mechanism, comprising a choke manifold structure, wherein a secondary buffer structure is fixed inside the choke manifold structure;

[0005] The choke manifold structure includes a choke manifold body connected to other pipes, and a buffer baffle is welded and fixed inside the choke manifold body, and the buffer baffle is arranged in a symmetrical manner;

[0006] The secondary buffer structure includes a through cylinder fixed to one side of the buffer baffle, and a mounting block is fixed inside the through cylinder for facilitating the fixed connection of one end of the damping shock absorber.

[0007] By adopting the above technical solution, a fixed connection is achieved through the provided mounting block.

[0008] Preferably, a through-hole disk is fixed to the other end of the damping shock absorber, and the through-hole disk is made of metal material, and the through-hole disk and the damping shock absorber form a buffering extrusion structure.

[0009] Preferably, the buffer baffles are provided in four groups, and the buffer baffles of a single group are arranged in a "V" shape.

[0010] By adopting the above technical solution, the buffer baffle is provided to achieve preliminary impact buffering.

[0011] Preferably, eight damping shock absorbers are provided, and the damping shock absorbers are arranged in a ring array inside the through cylinder.

[0012] By adopting the above technical solution, the damping shock absorber is provided to achieve elastic extrusion under stress.

[0013] Preferably, the through-hole disk and the through-tube are arranged in concentric circles, and the diameter ratio of the through-tube to the through-hole disk is 2:1.5.

[0014] By adopting the above technical solution, the provided through-hole disk can play a role in secondary impact buffering.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the choke manifold with a buffer mechanism,

[0016] (1) In this case, a buffer baffle is provided in the choke manifold structure to solve the problem that the liquid flowing inside the choke manifold has a corresponding impact force during the closing process of the choke manifold. When the liquid impact force is transmitted to the internal components of the choke manifold, the components will cause impact on the internal components of the choke manifold. If the impact is serious, it will cause a water hammer effect on the choke manifold. When the choke manifold is closed, the liquid inside the choke manifold will first come into contact with the buffer baffle. When the liquid first comes into contact with the buffer baffle, it will first act as a collision buffer for the liquid in the transportation process, reduce the flow rate of the liquid, and protect the internal components of the choke manifold.

[0017] (2) The above situation is solved by setting up a secondary buffer structure. The liquid passing through the buffer baffle will be pushed by the inertial thrust of the liquid behind to push the liquid in front to flow and contact the through-hole disk. When the liquid collides with the through-hole disk, the through-hole disk squeezes the damping shock absorber. During the process of squeezing the damping shock absorber, the flowing liquid is subjected to secondary collision buffering. The liquid that passes through the secondary buffer reduces the flow rate of the liquid and avoids the water hammer effect that is easy to occur inside the choke manifold.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5 The utility model provides a technical solution: a flow-blocking manifold with a buffer mechanism, such as Figure 1 and Figure 2 As shown, the choke manifold structure 1 includes a choke manifold structure 1, which includes a choke manifold body 101 installed and connected to other pipelines, and a buffer baffle 102 is welded and fixed inside the choke manifold body 101, and the buffer baffle 102 is arranged in a symmetrical manner. There are 4 groups of buffer baffles 102, and a single group of buffer baffles 102 is arranged in a "V" shape. When the above-mentioned components are arranged in 4 groups and 8 pieces, this not only reflects the practicality of the installation arrangement of the above-mentioned components, but also reflects the interception performance and liquid transportation fluidity of the installation arrangement of the above-mentioned components. When the above-mentioned components are arranged in 4 groups and 8 pieces, the axial symmetry of the installation arrangement of the above-mentioned components and the multiple collision buffering performance of the flowing liquid are simultaneously reflected.

[0026] In the above solution, when the choke manifold 101 is closed, the liquid inside the choke manifold 101 first impacts and contacts the buffer baffle 102 to initially reduce and disperse the impact force of the liquid.

[0027] like Figure 3 、 Figure 4 and Figure 5As shown, a secondary buffer structure 2 is fixed inside the choke manifold structure 1, and the secondary buffer structure 2 includes a through tube 201 fixed to one side of the buffer baffle 102, and a mounting block 202 is fixed inside the through tube 201 for fixing one end of the damping shock absorber 203. There are 8 damping shock absorbers 203, and the damping shock absorbers 203 are arranged in a ring array with respect to the inside of the through tube 201. When there are 8 of the above-mentioned components, it not only reflects the equidistant installation of the above-mentioned components, but also reflects the aesthetics and bidirectional fixity of the equidistant installation of the above-mentioned components. When there are 8 of the above-mentioned components, it also reflects the synchronous elastic extrusion and synchronous elastic recovery of the above-mentioned components under stress. When the damping shock absorbers 203 are arranged in a ring array with respect to the inside of the through tube 201, it reflects the axial and longitudinal axis symmetry of the above-mentioned components with respect to the inside of the through tube 201.

[0028] The above scheme further, the other end of the damping shock absorber 203 is fixed with a through-hole disk 204, and the through-hole disk 204 is made of metal material. At the same time, the through-hole disk 204 and the damping shock absorber 203 constitute a buffering extrusion structure, the through-hole disk 204 and the through-tube 201 are concentrically arranged, and the diameter ratio of the through-tube 201 to the through-tube 201 is 2:1.5. When the above two are installed and connected in concentric circles, not only the matching connectivity of the above two is reflected, but also the relative sliding pushing property of the above two is reflected. When the above two are concentrically arranged, the coaxial concentricity of the above two is reflected. The diameter ratio of the through-tube 201 to the through-hole disk 204 is 2:1.5. When the inner ring diameter of the through-tube 201 is 0.5 larger than the outer ring diameter of the through-hole disk 204, it is not only convenient for the through-hole disk 204 to be pushed and adjusted by the active force inside the through-tube 201, but also avoids the situation where the above two have motion interference and motion friction when the relative force is adjusted, thereby emitting harsh noise.

[0029] In the above scheme, when the liquid collides and contacts with the through-hole disk 204, the through-hole disk 204 squeezes the damping shock absorber 203, and the flowing liquid is subjected to secondary collision buffering during the force squeezing process of the damping shock absorber 203. The liquid after secondary buffering reduces the flow rate of the liquid and avoids the water hammer effect that is easy to occur inside the choke manifold 101.
