Abstract
The utility model relates to a high-pressure tee, which is used in production sites of the operation of petroleum drilling engineering construction. The utility model is composed of a main body (3) of the tee, a connecting press cap (4), a lower body (5) of the tee, a side pipe (6), a high-pressure valve set (2) and screw controlling pressure (1), wherein the main body (3) of the tee is connected with the lower body (5) of the tee below the main body (3) of the tee through the connecting press cap (4); one side of the main body (3) of the tee which tilts downwards is welded with the side pipe (6) which is communicated with the main body (3) of the tee; the middle part of the side pipe (6) is connected with the high-pressure valve set (2), and the screw controlling pressure is arranged in threaded holes at the lower part of the side pipe. The high-pressure tee has the advantages of reasonable design, novel structure and flexible and convenient operation and use; when the utility model is utilized, the abrasion to a connecting hose can be reduced, the service life of the connecting hose can be extended, the production cost is reduced, and meanwhile, the problem that workers carry out operation with pressure can be solved; the high-pressure tee is favorable for safe production.
Description
Technical field:
The utility model relates to a kind of pipeline link that is used for petroleum engineering construction operation, production scene.
Background technology:
Highpressure Tee is that the most frequently used pipeline in petroleum drilling and mining field construction operation, production scene connects one of auxiliary.At present, the on-the-spot Highpressure Tee that adopts usually mostly is stationary structure, can not adjust direction flexibly, thereby and flexible pipe between attended operation very inconvenient, and the spare and accessory parts spoilage height of threeway and hose transition spare.In addition,, cause the operator often to be with pressure work, buried hidden danger to safety in production owing to do not have pressure-release assembly on the existing Highpressure Tee.
Summary of the invention:
The purpose of this utility model is to provide a kind of and uses easy to operate, safe and reliable and can reduce Highpressure Tee to connecting the flexible pipe wearing and tearing, increasing the service life.
The utility model is to realize like this.This kind Highpressure Tee is made up of threeway main body, connection pressure cap, threeway lower body, side pipe, high pressure valve group and pressure control screw, the threeway main body is connected with the threeway lower body of its below by connecting pressure cap, threeway main body one side direction has a down dip tiltedly to be welded with and is attached thereto logical side pipe, the side pipe middle part is connected with the high pressure valve group, be provided with the pressure control screw in the screw of bottom, the lower end links to each other with the release of pressure flexible pipe.During use, the main body of this Highpressure Tee, lower body respectively by being threaded on the working position (for example production tree or wellhead assembly), and being injected pipeline with high pressure valve group and high-pressure pump and are connected.During work, the highly pressurised liquid of being exported by high-pressure pump (as slush pump or cementing truck) enters the threeway main body through high pressure valve group, side pipe, flows into the down-hole by connecting pressure cap and threeway lower body again, and the pressure control screw is closed at this moment.Construction finishes when needing pressure release, and the high pressure valve group is closed, and unclamps the pressure control screw, can discharge with the pressure in the flexible pipe that side pipe links to each other, thereby reaches the purpose of release of pressure.Because threeway main body and side pipe weld have 135 ° of angle of slope, and can rotate flexibly, thereby can reach optimum Working as required by the direction of swivel tee subject freedom adjustment high pressure valve group when mounted.
The utility model is reasonable in design, and novel structure uses flexible and convenient operation, utilizes it can significantly reduce connecting the wearing and tearing of flexible pipe, increases the service life, and reduces production costs, and can solve the problem of workman's Operating Pressure simultaneously, helps safety in production.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of threeway main body 3, connection pressure cap 4, threeway lower body 5, side pipe 6, high pressure valve group 2 and pressure control screw 1, its structure, assembled relation are as follows: threeway main body 3 is connected also rotatable by connecting pressure cap 4 with the threeway lower body 5 of its below, threeway main body 3 one side direction have a down dip tiltedly to be welded with and are attached thereto logical side pipe 6, side pipe 6 middle parts are connected with high pressure valve group 2, are provided with pressure control screw 1 in the screw of bottom.Wherein, threeway main body 3 is a pipe body, its upper end is provided with internal thread, the thread segment below blocks, and the lower end is provided with external screw thread, and a side is provided with a side direction through hole, become 135 ° of angles to have a down dip with it outside the through hole and tiltedly weld a side pipe 6, threeway lower body 5 is a pipe that matches with threeway main body 3, and its upper end is provided with and is connected the round platform that pressure cap matches, and the lower end is provided with internal thread.Connect pressure cap 4 upper ends and be provided with the internal thread that matches with threeway main body 3 lower end external screw threads, the lower end is provided with the step that matches with threeway lower body 5.
Claims (1)
1, a kind of Highpressure Tee, form by threeway main body (3), connection pressure cap (4), threeway lower body (5), side pipe (6), high pressure valve group (2) and pressure control screw (1), it is characterized in that: threeway main body (3) is connected also rotatable by connecting pressure cap (4) with the threeway lower body (5) of its below, becoming 135 ° of angle lappings tiltedly to be welded under threeway main body (3) one side direction is attached thereto on the logical side pipe (6), side pipe (6) middle part is connected with high pressure valve group (2), is provided with pressure control screw (1) in the screw of bottom.
