Description
Technical field
The utility model relates to a kind of pipe joint, refers in particular to a kind of pine cover spherical joint.
Background technique
Pine cover spherical joint is a kind of assembling pipe joint with large deflection, and it can free deflection in 30 ° of scopes, and serious to remedy because of foundation settlement, and external force effect and the pipeline deflection that produces and pipeline turn round etc. under the situation problem that may occur.
Existing pipeline adopts mostly that flange connects, is threaded, socket joint connects and form such as clip connected, and all there are some problems more or less in these forms, and connecting with being threaded as flange is rigidity basically, and deflection does not have influence on the laying of pipeline; Socket joint and clip connected utilize the distortion of seal ring to obtain certain flexible amount, but amount of deflection is very little; Generally speaking, pipeline all exists the distortion of foundation settlement and pipeline to cause and reach deflection problem inevitably, forms the destruction to pipeline.
Summary of the invention
The purpose of this utility model is to design a kind of pine cover spherical joint, and this spherical joint had both had rigidity preferably, had good amount of deflection again, had guaranteed the quality of pipeline.
Its main technical schemes comprises shell and body, it is characterized in that on shell forming one section spherical shell that inner chamber is spherical in shape, and one section sphere that cooperates with spherical shell is arranged on body accordingly, and body utilizes link to cooperatively interact with spherical shell to be connected.
The sphere of described body stretches in the spherical shell, end at spherical shell connects gland, one section inwall in close its end of spherical shell is provided with one section part that radially expands outwardly, inwall at spherical shell forms a step, the end of gland extends the step place, the inner wall shape of gland constitutes a spherical inner chamber with the inner wall shape of spherical shell, and cooperates with the sphere of body; Between the end face of the step of spherical shell and gland, seal ring is set.
The other end at body connects end cap; Connecting end inwall at body and end cap is provided with one section horn opening, in the toroidal cavity that forms between this horn opening and end cap seal ring is set, the internal diameter of seal ring after extruding less than the internal diameter of body; End outer wall at the close end cap of body is provided with axial screw, and corresponding screw is set on end cap, and end cap utilizes bolt and screw to be connected with body.
The other end at shell is provided with flange, and through hole is set on flange.
After the utility model has the advantages that shell and body utilize sphere to cooperatively interact to be connected, guaranteeing to have between shell and body under the prerequisite of enough rigidity, making again between shell and body and can relatively rotate, guaranteeing that it has certain amount of deflection; Seal ring utilizes gland to be pressed on the smooth sphere, utilizes the seal ring extrusion, and the selfsealings performance of y-shaped ring reaches the effect of sealing and deflection; The joint socket place utilizes gland to compress the wedge shape seal ring, makes the seal ring distortion, is pressed on the connected pipeline, plays sealing and the effect that is connected, and has certain extending amount.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Embodiment
As shown in the figure: form one section spherical shell 9 that inner chamber is spherical in shape on shell, one section sphere 11 that cooperates with spherical shell 9 is arranged on body 5 accordingly, body 5 utilizes link to cooperatively interact with spherical shell 9 to be connected.After shell and body 5 utilize sphere to cooperatively interact to be connected, guaranteeing to have between shell and body under the prerequisite of enough rigidity, making again between shell and body and can relatively rotate, guaranteeing that it has certain amount of deflection.
The sphere 11 of body 5 stretches in the spherical shell 9, end at spherical shell 9 connects gland 3, one section inwall in spherical shell 9 close its ends is provided with one section part that radially expands outwardly 12, inwall at spherical shell 9 forms a step 10, the end of gland 3 extends step 10 places, the inner wall shape of gland 3 constitutes a spherical inner chamber with the inner wall shape of spherical shell 9, and cooperates with the sphere 11 of body 5.Spherical shell 9 utilizes inwall gland also spherical in shape 3 to interconnect with body 5, on the inwall of gland 3 and spherical shell 9, form a concentric spherical, utilize this spherical to cooperate again with sphere 11 on the body 5, realize being rotationally connected between spherical shell and body, this Placement is fairly simple and reliable, can also between the end face of the step 10 of spherical shell 9 and gland 3, y-shaped ring 2 be set, further improve its sealability.
The other end at body 5 connects end cap 8, and the effect of end cap 8 is connecting tube.
Connecting end inwall at body 5 and end cap 8 is provided with one section horn opening, in the toroidal cavity of this horn opening and 8 formation of end cap, wedge shape sealing ring 6 is set, the internal diameter of seal ring 6 after extruding less than the internal diameter of body 5, produce when avoiding connecting tube and leak, should seal ring 6 be set at its joint.
