Abstract

The utility model relates to a universal pipe joint, belonging to the field of universal pipe joints. The universal pipe joint comprises a left housing, a screw bolt, a compaction stop ring, a right housing, a low-pressure seal ring, a high-pressure seal ring and a spherical core body, wherein the right housing is of a circular ring body, a round platform is arranged at one end of the circular ring, the end surface of the left housing is in contact with the bottom surface of the round platform, the low-pressure seal ring and the high-pressure seal ring are arranged between the contact surfaces, the left housing and the right housing are connected through the compaction stop ring and the screw bolt, spherical arcs are arranged on the inner walls of the left housing and the right housing, the spherical core body is positioned in the spherical arcs, and a connecting port is formed at one end of each of the left housing and the spherical core body. The universal pipe joint has the advantages that the mounting space of a hoop is small, the weight of the pipe joint is light, and the universal pipe joint is convenient to disassemble and assemble; and the universal pipe joint can revolve or deflect around the axial lead of a connecting body by relying on articulation of the left housing and the spherical core body by penetrating through the middle parts of the left housing and the spherical core boy, and the stop ring is mounted on the right housing through the screw bolt, so that the left housing and the right housing can be effectively prevented from becoming loose after the screw bolt is screwed up, and reliability in self-locking and tight sealing properties of the universal pipe joint in a working state can be ensured.

Description

Universal pipe joint

Technical field

The utility model relates to the swivel union that a kind of pipeline connects, particularly a kind of universal pipe joint.

Background technique

At present, pipe joint mainly contains two kinds: a kind of is the oriented tube joint, and a kind of is swivel union.Long distances pipeline and the down-hole pipeline of arranging all uses the oriented tube joint mostly, but at a kind of pipe joint that can arbitrarily change direction and easy accessibility in light weight of some special dimensions needs.The turned to elbow that common use is 90 ° is realized the break-in of current.This elbow that turns to has only one degree of freedom, just needs the turned to elbow of two 90 ° of series connection if realize universal rotation.The advantage of this universal pipe joint is relatively simple for structure, compact.Shortcoming be fluid through twice 90 ° turn to the back kinetic energy rejection big, therefore can not be used for carrying high-velocity fluid.

The model utility content

The purpose of the utility model is that a kind of universal pipe joint will be provided, solve two the series connection 90 ° turned to elbow fluid through twice 90 ° turn to the back kinetic energy rejection big, the problem that can not be used for carrying high-velocity fluid.

The purpose of the utility model is achieved in that this universal pipe joint comprises: left shell, bolt, compress stopping ring, right shell body, low pressure seal circle, high-pressure seal ring and ball core body; Right shell body is a cirque body; At a toric end round platform is arranged, the end face of left shell contacts with the bottom surface of round platform, and low pressure seal circle and high-pressure seal ring are arranged between surface of contact; Left shell is connected with bolt through compressing the stopping ring with right shell body; At left shell and right shell body inwall the spheroidal arc is arranged, the ball core body is arranged in the spheroidal arc, and it is the connecting port that an end is all arranged on left shell and ball core body.

Beneficial effect: owing to adopted such scheme, universal pipe joint can play high pressure sealing in the paste body filling pipeline, around the regulating action of revolution of connecting body shaft axis or deflection; High-pressure seal ring and low pressure seal circle are arranged between the contact seal face between its left shell and the right shell body; Sealing structure is that left shell and right shell body bolt are screwed and carried out prestressing force and compress sealing; Initial low pressure is sealed by rubber seal, and the working voltage operating mode is sealed by the modified Teflon seal ring.

Loosening in order to prevent that left shell and right shell body after bolt is screwed into from producing moment under alternating stress, on right shell body, the stopping ring has been installed with bolt, guarantee self-locking and the tight reliability of sealing under the universal pipe joint working state.The turned to elbow fluid that has solved 90 ° of two series connection through twice 90 ° turn to the back kinetic energy rejection big, the problem that can not be used for carrying high-velocity fluid has reached the purpose of the utility model.

Advantage: the clip installing space is little, tube coupling is in light weight, be convenient to dismounting.Universal pipe joint is that keep left housing and ball core body plays around revolution of connecting body shaft axis or deflection for middle connect hinged; High-pressure seal ring and low pressure seal circle are arranged between the contact seal face between its left shell and the right shell body, are that bolt is screwed and carried out prestressing force and compress sealing. initial low pressure is sealed by rubber seal, and normal high pressure operating mode is sealed by teflin ring.On right shell body, the stopping ring has been installed, has been prevented that effectively left shell and the right shell body after bolt is screwed into is loosening, guaranteed self-locking and the tight reliability of sealing under the universal pipe joint working state with bolt.

Description of drawings

Fig. 1 is the structural drawing of the utility model.

Among the figure, 1, left shell; 2, bolt; 3, compress the stopping ring; 4, right shell body; 5, low pressure seal circle; 6, high-pressure seal ring; 7, ball core body.

Embodiment

Embodiment 1: this universal pipe joint comprises left shell 1, bolt 2, compresses stopping ring 3, right shell body 4, low pressure seal circle 5, high-pressure seal ring 6 and ball core body 7; Right shell body 4 is a cirque body; At a toric end round platform is arranged, the end face of left shell 1 contacts with the bottom surface of round platform, and low pressure seal circle 5 and high-pressure seal ring 6 are arranged between surface of contact; Left shell 1 is connected with bolt 2 through compressing stopping ring 3 with right shell body 4; At left shell 1 and right shell body 4 inwalls the spheroidal arc is arranged, ball core body 7 is arranged in the spheroidal arc, and on left shell 1 and ball core body 7, an end being arranged all is the connecting port.

Universal pipe joint left shell 1 one ends and pipeline are used clip connected, and the other end ball core body 7 is also used clip connected with pipeline, form the inner cavity of pipe sealing and connect.

When the direction in space angle displacement appearred in installation pipeline, left shell 1 was hinged around revolution of connecting body shaft axis or deflection with the spherical cambered surface of ball core body 7, plays the adjusting and the compensating action of direction in space angle displacement.

Occur lotion when preventing angle displacement and ooze and let out, contacting with high-pressure seal ring 6 and low pressure seal circle 5 between left shell 1 and the right shell body 4 seals, and initial low pressure is sealed by rubber seal, and normal high pressure operating mode is sealed by teflin ring.

Left shell 1 carries out the prestressing force pressed sealing device with outstanding tight installation of right shell body 4 screw threads. just answer the impacting force adjustment in advance according to pipe-line system pressure.

Tightly advance back becoming flexible in order to prevent that left shell 1 and right shell body 4 screw threads from hanging, on right shell body 4, be uniformly distributed with 12 bolts 2 and compress stopping ring 3, guarantee integrally-built self-locking and sealing reliability.

But universal pipe joint has implementation space three-dimensional angular displacement, and pipeline internal channel easy to operate in light weight can keep advantage such as smooth and easy again.
