Description
Technical field
The present invention relates to a kind of connection of cast tube, specifically a kind of casting pipe automatic anchor interface particularly relates to a kind of self-anchored type interface that adopts the ductile iron pipe of vacuum expendable pattern modulus method production.
Background technique
At present, when cast tube is connected into pipeline, generally be in the bellmouth inner groovy of cast tube, to put into seal ring, the socket of another root cast tube inserts in the bellmouth of described cast tube, seal ring tightly is squeezed between the bellmouth and socket of cast tube, realizes sealing and anti-slip with this.The pipeline bearing capacity that this method is completed is poor, and anti-radial deformation is poor, occurs owing to the socket slippage of cast tube is leaked easily; And efficient is low,, waste time and energy, long in time limit.
The patent No. is 02154491.3, the applying date is on September 17th, 2003, denomination of invention be casting pipe automatic anchor interface patent disclosure a kind of self-anchored type interface, external cylindrical surface cover in cast tube sockets and socket joint has clip, described clip radial equipartition locking socket tapped hole and locking bellmouth tapped hole, locking socket spiral shell, pit is groove near the socket external cylindrical surface, pressure ring is housed in the groove slidably, locking socket spiral shell, the tight bolt of pit inward turning combined pressure, the inner of hold-down bolt is pressed on the pressure ring, screw hold-down bolt, pressure ring presses the socket external cylindrical surface, clip and socket are decided to be one together, are combined with lock bolt in the described locking bellmouth tapped hole, two cast tubes that will be connected by clip are fixed together.Its complex structure, when pipeline pressure raise, the convex shoulder of clip was easy to break, thereby had lost out from anchor and anti-slip performance.
Summary of the invention
The purpose of this invention is to provide a kind of casting pipe automatic anchor interface that is applied to the high pressure pipeline.
The present invention adopts following technological scheme to realize its goal of the invention, a kind of casting pipe automatic anchor interface, it comprises socket, the bellmouth of cast tube, socket is provided with bulge loop, bellmouth is provided with boss, bellmouth and socket link into an integrated entity by baffle ring, differential, j-bolt, and namely baffle ring is located between differential, the bulge loop, the gib head that is installed in the j-bolt on the differential be hooked on the inclined-plane of boss and by fastening nuts on differential.
The j-bolt that the present invention is installed on the differential is at least more than 2.
The angle of the surface of contact between inclined-plane of the present invention and boss, the differential is 15 °≤α≤45 °.
One of the present invention preferably practical range is that the angle of the surface of contact between described inclined-plane and boss, the differential is 20 °≤α≤30 °.
One of the present invention preferably embodiment is that described α equals 25 °.
Because adopt technique scheme, the present invention has realized goal of the invention preferably, have simple in structurely, easily manufacturing can realize many pipeline integral hoistings, easy construction can be applicable to the construction of high pressure pipeline.

Embodiment
The invention will be further described below in conjunction with drawings and Examples.
Embodiment 1:
As shown in Figure 1, a kind of casting pipe automatic anchor interface, it comprises socket 1, the bellmouth 5 of cast tube, socket 1 is provided with bulge loop 10, bellmouth 5 is provided with boss 7, bellmouth 5 and socket 1 link into an integrated entity by baffle ring 3, differential 2, j-bolt 4, and namely baffle ring 3 is located between differential 2, the bulge loop 10, the gib head that is installed in the j-bolt 4 on the differential 2 be hooked on the inclined-plane 8 of boss 7 and by fastening nuts on differential 2.
The j-bolt 4 that the present invention is installed on the differential 2 is at least more than 2, and present embodiment is 30.
The angle of the surface of contact between inclined-plane 8 of the present invention and boss 7, the differential 2 is 15 °≤α≤45 °, and as shown in Figure 2, present embodiment is that α equals 45 °.
When the present invention installs, put into seal ring 6 in the groove of the bellmouth 5 of cast tube, the socket 1 of another root cast tube inserts in the bellmouth 5, seal ring 6 tightly is squeezed between the bellmouth 5 and socket 1 of cast tube; Bellmouth 5 and socket 1 link into an integrated entity by baffle ring 3, differential 2, j-bolt 4.
Embodiment 2:
One of the present invention preferably practical range is that the angle of the surface of contact between described inclined-plane 8 and boss 7, the differential 2 is 20 °≤α≤30 °, and embodiment is that described α equals 25 ° preferably.
As shown in Figure 3, α of the present invention equals 25 °.Remaining with embodiment 1.
Embodiment 3:
α of the present invention equals 30 °.Remaining with embodiment 1.
Embodiment 4:
α of the present invention equals 15 °.Remaining with embodiment 1.
As shown in Figure 4, the present invention when caliber be D, when the pressure of pipeline was P, under stressed uniform condition, the pressure that shirt rim 9 is subject to was F=[P * π * (D/2)
2] ÷ 30 * cos (90 °-α).
From above formula as can be known, along with reducing of α angle, the pressure F that shirt rim 9 is subject to also reduces.The present invention is through test, and when getting the pipe fitting that specification is DN800, when α equaled 15 ° or 25 ° or 30 ° or 45 °, the pressure of pipeline can reach 1.6MPa, and in embodiment 2, the pressure of its pipeline can reach 4.5MPa.Take the axial force that j-bolt 4 bears into consideration, preferred embodiment of the present invention is that α equals 25 °.
