Description
Technical field
The utility model relates to a kind of pipe joint, refers to a kind of pipeline movable telescopic interface especially.
Background technique
At present, in pipeline construction, perhaps keep in repair, when rushing to repair, adopt traditional pipeline " six join greatly " mostly or adopt the mode of directly welding to carry out.There is following defective in these traditional forms of construction work:
1, in the bigger job site of workload, such as: the line transportation of domestic water supply, heating, air feed and chemical industry etc., because there is certain difference in design and construction, several mm of error that produce are to tens mm, even mm up to a hundred are very general, during piping erection, and can not whole blanking, only carry heavy instrument site operation, time-consuming, take a lot of work, waste material.
2, at the terminal point interface of pipeline construction, or intermediary interface and with the connection mouth of valve, measuring instrument, radiator, hot cold mixing arrangement, water heater etc., because limitation of field condition is easy to during butt joint cause the pipeline unbalance stress, causes the reduction safety coefficient.
3, in practice of construction, both sides are taken over not point-blank, and when using general active interface to connect, difficulty relatively, and damage screw thread easily.
4, because for satisfying field condition, the button silk of connection mouth is less, very easily damages because of corrosion.
5, use the welding method interface, the connection mouth of especially big caliber had both influenced attractive in appearancely, took a lot of work again, waste material.Field operation is difficult to reach standard-required in addition, and therefore, rate of fault is higher.Cause later maintenance difficult, the influence safety in production.
The model utility content
The purpose of this utility model provide a kind of adjust the interface spacing, time saving and energy saving, improve the pipeline pipeline movable telescopic interface in working life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pipeline movable telescopic interface is made of base interface, attaching nut, flexible interface.Base interface is made of fixedly screw mandrel, interface, telescopic cavity, and the attaching nut is made of set screw nut, adjusting nut, flexible interface by regulate screw mandrel, interface constitutes.The fixedly screw mandrel of base interface is threaded with set screw nut, and the interface of base interface is threaded with pipe joint.The adjusting screw mandrel of flexible interface is threaded with adjusting nut, and stretches in the telescopic cavity, regulates screw mandrel and cooperates with telescopic cavity is movable, and the interface of flexible interface is threaded with pipe joint.
Adjusting screw mandrel in the above-mentioned pipeline movable telescopic interface, described telescopic cavity is provided with the packing ring, is provided with seal ring in the circumferential recess on packing ring side face, and the packing ring is connected with the adjusting wire rod thread, and locatees by bearing pin.
Above-mentioned pipeline movable telescopic interface, described interface are nut or screw mandrel, and described pipe joint is screw mandrel or nut.
The beneficial effects of the utility model are:
1, adopt base interface, attaching nut, flexible interface to constitute pipeline movable telescopic interface, the adjusting screw mandrel of flexible interface is in the attaching nut stretches into the telescopic cavity of base interface.Have following beneficial effect:
1), the distance between can the adjutage pipeline joint, only need carry fastened tools and get final product, save time, saving of labor, material-saving the raising operating efficiency.Simultaneously, avoided deviation because of blank size make pipeline produce in the pipe deforming that causes of pulling force or extrapolability.Guarantee that pipe safety uses, is without prejudice.
2), utilize two ends interface thread, middle wire rod thread 3 place's screw threads to regulate simultaneously, effectively avoided the difficulty of construction that point-blank do not produce because of interface two ends pipeline big, decrease phenomenon such as button, solved the mismatch problem preferably, the grade that improves the quality greatly and safety coefficient.
2, adopt interface and connected pipe joint screw mandrel, nut each other.Interface can be processed into internal thread, also can be processed into outer silk, according to the inside and outside silk shape of the mouth as one speaks of pipe joint, the inside and outside silk shape of the mouth as one speaks of adjusting base interface and flexible interface gets final product.Simultaneously, also can carry out the reducing interface according to the caliber of pipe joint.Significantly reduced Connection Step, convenient, efficient, safe and reliable.
3, adopt the adjusting screw mandrel in the telescopic cavity to be provided with the packing ring, be provided with seal ring in the circumferential recess on packing ring side face.Can in the pipeline construction of seal request strictness, reach desirable sealing effect.
The utility model will stretch the adjusting screw mandrel of interface in the attaching nut stretches into the telescopic cavity of base interface, not only can adjutage pipeline joint spacing, and also easy construction, safety durable; Effectively avoided because of phenomenons such as pipeline misplaces, the imprecise difficulty of construction that causes of pipe joint spacing is big, it is insecure to install, screw thread damages.The interface that is widely used in plumbing pipe, feed channel, chemical industry pipeline etc. is installed.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
