Abstract
The utility model discloses a universal joint, which is a pipeline joint for pipeline compensation. The universal joint is composed of a connection pipe, a casing pipe which can universally rotate corresponding to the connection pipe, and a telescopic pipe which can slide and extend on the connection pipe. The casing pipe is connected with the connection pipe by a connection pressing plate. The telescopic pipe is connected to the connection pipe by the clamping step of a clamping step plate. The universal joint can compensate for the positional deviation generated by pipelines and oil storage tanks and length changes caused by heat expansion and cold contraction.
Description
The utility model relates to a kind of compensation of pipeline link.
In the oil field, tank farm such as oil port and pier and petroleum refinery, oil transport pipeline and oil storage tank more or less exist sinkage, and the sinking degree of the sinking of oil transport pipeline and oil storage tank is different often.Because fracture or oil leakage phenomenon easily take place in this uneven joint that makes transport pipe and oil storage tank that sinks down into, and generally will use pipeline compensator to compensate for preventing this from occurring.Present more employing be the adapter compensator made from Stainless Steel Flexible Hose because the sealing layer of this compensating connector is fragile, the cost height, is changed difficulty at the maintenance of compensating connector, so its using effect is undesirable.
The purpose of this utility model provides that a kind of cost is low, and compensation effect is reliable, and long service life, is changed the universal joint convenient, that expense is low at maintenance.
Universal joint by an end have the sphere wall adapter, wear take over the insertion hole wall for take over sphere curved surface that sphere tube wall face matches be connected pressure strip and an end tube chamber wall for constituting with the sleeve pipe of taking over the sphere curved surface that sphere tube wall face matches, sleeve pipe, connect pressure strip and be set on to take over to tighten and connect sphere curved surface wall that the back connects pressure strip, sleeve pipe and take over that the sphere wall cooperates and evenly tight subsides are touched, sleeve pipe can be relative to taking over universal the rotation.On the sleeve pipe sphere curved surface tube chamber wall annular groove is arranged, O-ring seal is crouched in the groove and with sleeve pipe and adapter sphere wall sealing joint.
Different use in order to adapt to, installation requirement, can to adopt screw connection structure also can adopt flange, clamping bolt linkage structure to carry out fastening fixedly connected with being connected pressure strip for sleeve pipe, the adapter end of adapter, sleeve pipe can make spiral shell also can be welded to connect flange so that adapter.
Further improving of universal joint is in the adapter of universal joint the telescopic tube that can come and go slippage on taking over to be arranged, and the telescopic tube sleeve is fastenedly connected block and is connected in the adapter by being sleeved on block plate in the adapter on taking over.Telescopic tube tube chamber wall and block plate poling wall surface of the hole touch with taking over evenly tight subsides of wall, and taking on wall and the block plate poling hole wall surface of the hole has annular groove, and O-ring seal is crouched in the groove and with sealing joint.
In order to adapt to different installations and usage requirement, block plate and telescopic tube can adopt screw connection structure, and it is fastening fixedly connected also can to adopt flange, bolt fastening structure to carry out.
Universal joint can carry out the compensation of the positional deviation of pipeline, the also length change compensation that can expand with heat and contract with cold.Universal joint is a modular construction, and it is convenient, easy to install, overhaul, and sealing gasket is not fragile, the joint long service life, and compensation effect is reliable, can satisfy difference and use the requirement of installation.
Accompanying drawing is embodiment of the present utility model, further specifies the utility model below in conjunction with embodiment.
Fig. 1 is universal joints structure figure.
Fig. 2 is the structural drawing that has the universal joint of telescopic tube.
As shown in Figure 1, the tube wall face (4) that universal joint is taken over (3) one ends is a sphere curved surface tube wall face, and taking over end has whole flange connecting (2).The sphere curved surface of sleeve pipe (6) one end tube chamber walls (5) for matching with adapter sphere tube wall face is fastened in the sphere curved surface that stressed joint pressure strip (1) insertion hole wall surface of the hole is and adapter sphere curved surface tube wall matches in the adapter.There are whole flange connecting (8) and (9) in the sleeve pipe two ends, by bolt (7) sleeve pipe and connecting plate are fasteningly fixedly connectedly made sleeve pipe, are connected pressure strip sphere wall and evenly closely paste and touch with taking over sphere curved surface tube wall face, and sleeve pipe can universally rotate relative to adapter.On the sleeve pipe sphere tube chamber wall annular groove is arranged, O-ring seal (10) is crouched in the groove and with the sphere curved surface sealing joint of universal joint.
As shown in Figure 2, adapter (12) upper sleeve that has a universal joint of telescopic tube has telescopic tube (17).Take over adjacent end annular retaining platform (14) is arranged.Telescopic tube tube chamber wall matches to merge evenly closely to paste with the adapter wall and touches, and telescopic tube can often free slippage in adapter.Block plate (16) is sleeved in the adapter, block plate insertion hole wall matches to merge evenly closely to paste with the adapter wall and touches, and the block plate makes telescopic tube be connected in the adapter by annular retaining decometer retaining by fastening the fixedlying connected of adpting flange (18) that bolt (19) and integral body are connected on the telescopic tube.Taking on tube wall face and the block plate insertion hole wall has annular groove, crouches in the groove and with sealing joint in O-ring seal (15) and (13).During use when oil storage tank, transport pipe when sinking uneven occurrence positions deviation, sleeve pipe (11) can carry out position compensation relative to taking over to rotate.When temperature variation is expanded with heat and contract with cold, telescopic tube can be on taking over slippage change universal joint length and duct length is changed compensate.
Claims (2)
1, a kind of universal joint, it is characterized in that having the adapter of sphere wall by an end, wear take over the insertion hole wall surface of the hole for take over sphere curved surface that sphere tube wall face matches be connected pressure strip and an end tube chamber wall for constituting with the sleeve pipe of taking over the sphere curved surface that the sphere wall matches, sleeve pipe, the connection pressure strip is set on to take over to tighten and connects back connection pressure strip, sleeve pipe sphere curved surface wall cooperates with adapter sphere wall and evenly closely pastes and touch, sleeve pipe can be relative to taking over universal the rotation, on the sleeve pipe sphere curved surface tube chamber wall annular groove is arranged, O-ring seal is crouched in the groove and with sleeve pipe and adapter sphere wall sealing joint.
2, by the described universal joint of claim 1, it is characterized in that the telescopic tube that can come and go slippage on taking over is arranged in the said adapter, telescopic tube is connected in the adapter with the fastening block of fixedlying connected of the block plate on being sleeved on adapter, taking on wall and the block plate poling hole wall surface of the hole has annular groove, and O-ring seal is crouched in the groove and with sealing joint.
