Abstract
The utility model relates to a throttle manifold part, provides a puncture-proof short section and aims to solve the problem that potential safety hazards exist in a drilling process due to the fact that existing puncture-proof short sections can not effectively slow down fluid velocity. The puncture-proof short section comprises an inlet inlaid with a hard alloy sleeve, a pipeline, an outlet, a puncture-proof flange, a sealing device and a fixing device, the outlet is a detachable alloy short section, the alloy short section comprises a spherical surface and through holes, the spherical surface is sealed and protruded inwards, and the through holes are arranged on the periphery of the spherical surface. According to the puncture-proof short section, the hard alloys are arranged on inner walls of the inlet, the outlet and the pipeline to improve the washout resisting performance of the short section, the spherical surface outlet is arranged to disperse impulse force of a fluid and change a direction of the fluid, by means of an eddy current formed by the fluid flowing out from the through holes, the speed of the fluid is further reduced, a downstream pipeline of a throttle manifold can be effectively protected, and the safety coefficient of well control is improved.
Description
Technical field
The utility model relates to a kind of drilling well choke manifold device, refers to especially a kind of anti-stab pipe nipple.
Background technology
Generally, the choke valve downstream of choke manifold is that the exit is equipped with a casing connecting spool that studs with alloy, to reduce fluid to the erosion of downstream line.This pipe nipple that studs with alloy is simple tubular structure, especially in the situation of high pressure high-yield well, can not reduce fast the speed of fluid, the fluid erosion prevention DeGrain.There are risk in the downstream pipeline of the easy erosion choke manifold of fluid at a high speed, so that choke manifold inefficacy to well control, cause potential safety hazard.
The utility model content
The utility model proposes a kind of anti-stab pipe nipple, a kind of equipment that can reduce fast and effectively fluid velocity is provided.
The technical solution of the utility model is achieved in that a kind of anti-stab pipe nipple, comprises the import, pipeline, outlet, anti-stab flange, sealing device and the fastening devices that stud with the carbide alloy cover, and outlet is dismountable alloy pipe nipple; This alloy pipe nipple comprises the through hole that arranges around the inwardly protruded sphere of sealing and the sphere.
Above-mentioned sphere is hemisphere face.
Be provided with at least two through holes around the above-mentioned sphere.
Further, be provided with four through holes around the sphere.
Described inner-walls of duct built-up welding has hard alloy layer.
Described sealing device comprises gasket ring, back-up ring and pressure cap.
Described fastening devices comprises Double-ended nut.
A kind of anti-stab pipe nipple that the utility model provides by in import and outlet and inner-walls of duct carbide alloy being set, improves abrasion-resistance of the present utility model; By the sphere outlet is set, the impulse force of dispersing fluid changes the direction of fluid, and utilizes the eddy current that forms between the fluid of being gone out by through hole, further reduces the speed of fluid, effectively protects the downstream pipeline of choke manifold, improves the safety factor of well control.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1: the utility model structural representation.
Fig. 2: the schematic top plan view of alloy pipe nipple.
Wherein: 1-import, 2-pipeline, 3-alloy pipe nipple, 4-anti-stab flange, 5-sphere, 6-through hole, 7-gasket ring, 8-back-up ring, 9-pressure cap, 10-Double-ended nut.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
A kind of anti-stab pipe nipple that the utility model provides comprises the import 1, pipeline 2, outlet, anti-stab flange 4, sealing device and the fastening devices that stud with the carbide alloy cover, and outlet is dismountable alloy pipe nipple 3; This alloy pipe nipple 3 comprises the through hole 6 that arranges around the inwardly protruded sphere 5 of sealing and the sphere 5.Above-mentioned sphere 5 is hemisphere face.Be provided with at least two through holes 6 around the above-mentioned sphere 5.In the present embodiment, be provided with four through holes 6 around the sphere 5.Described pipeline 2 inner wall overlayings have hard alloy layer.Described sealing device comprises gasket ring 7, back-up ring 8 and pressure cap 9.Described fastening devices comprises Double-ended nut 10.
In specific implementation process; fluid enters the utility model pipeline 2 cavitys by import 1; the hard alloy layer of built-up welding protection the utility model is not by erosion in pipeline 2 cavitys; fluid is got to alloy pipe nipple 3 spheres 5; sphere 5 disperses the impulse force of fluid; then fluid is beaten at cavity inner wall everywhere, flows out finally by cavity through hole 6, and the eddy current of formation further reduces the speed of fluid.Effectively the protection downstream line has reduced the potential safety hazard of drilling process not by fluid erosion.
A kind of anti-stab pipe nipple that the utility model provides by in import and outlet and inner-walls of duct carbide alloy being set, improves abrasion-resistance of the present utility model; By the sphere outlet is set, the impulse force of dispersing fluid changes the direction of fluid, and utilizes the eddy current that forms between the fluid of being gone out by through hole, further reduces the speed of fluid, effectively protects the downstream pipeline of choke manifold, improves the safety factor of well control.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
