Abstract
The invention relates to a pipe joint, which is indispensable in connection of various metal pipelines and widely applied to weldless connection of metal pipes with the diameter smaller than 60mm and used for delivering various liquid and gaseous media in the fields of chemical industry, engineering machinery, electricity, trains and metallurgy and the like. The clamping type pipe joint is characterized in that a nut, a clamping snap ring, a sealing gasket and an O-shaped rubber ring are sleeved on a pipe to be mounted in sequence, one end of the pipe is inserted into the pipe joint, an inner conical hole is arranged in the nut and in arc fit with an outer arc of a small end of the clamping snap ring, the clamping snap ring and the sealing gasket are pushed by rotating the nut to press the O-shaped rubber ring between an inner step of a pipe joint end and an outer circle of the metal pipe through the inner conical hole of the nut, and accordingly, reliable sealing performance is achieved. Since the clamping snap ring is split and a zigzag annular cutting edge is arranged in the inner hole of the clamping snap ring, the clamping snap ring is pressed under the action of the inner conical hole of the nut, the zigzag annular cutting edge is pressed into the surface of the pipe to form effective incisions, and connection strength is high.
Description
Technical field
The present invention relates in all kinds of metal tubes connection the design and the manufacturing of indispensable pipe joint, be widely used in various chemical industry, engineering machinery, electric power, train, control golden equal diameter and connect in succession less than the solderless in the metal tubes of each class I liquid I of 60mm, gas medium.
Background technique
At present; The connecting means of the various metallic conduits of extensive use has welding type and pipe joints such as flared type and flange-type in every profession and trade; Since need welding at the scene or flared fitting need carry out pipe enlarging operation, so installation cost is high, inefficiency; Installation process is complicated, lacks safety reliability; The compression type pipe joint is as long as directly use spanner just can accomplish installation exercise in the occasion of any complicacy; It is simple to operation, speed is fast; Safe and reliable, be particularly suitable for being installed in sharp pounding and the stronger occasion of impact force, in the braking pilot line system on the bullet train.
Summary of the invention
The object of the present invention is to provide good, anti-sharp pounding of a kind of sealability and impact, safe and reliable, simple in structure, simple installation is pipe joint efficiently.
Technological scheme of the present invention is:
The present invention by fittings body, compress snap ring, gasket seal, rubber o-ring and nut and form, nut, compress snap ring, gasket seal and rubber o-ring penetrate successively on the pipe that will install, tube end inserts in the fittings body; Fittings body is provided with the interior step that matches with rubber o-ring with the connecting port of pipe; The outside that compresses snap ring is a circular arc, and there is size at two end part, and endoporus is provided with zigzag fashion ring-type blade, and is processed into cut; The inner female cone hole of nut cooperates with the small end external arc that compresses snap ring, and swivel nut compresses snap ring and gasket seal through the promotion of female cone hole and compresses rubber o-ring in splice port between step and the metal tube cylindrical, the formation reliable sealing performance; Because compressing snap ring is cut; And its endoporus is provided with zigzag fashion ring-type blade; Under the promotion of nut internal taper hole, the big end that compresses snap ring promotes the end face that gasket seal terminates in fittings body, impels to compress the snap ring contraction; Zigzag fashion ring-type blade ascending pipe sub-surface forms effective incision, produces firm join strength.The compression type pipe joint is according to different requirement and working medium; The joint and the pipe of the materials of confirming to adapt such as carbon steel, stainless steel or brass; And straight-through, curved logical, the threeway, the four-way transition joint that are provided with all size be connected pipe with an end, and the other end is connected with equipment leads directly to, bends each verieties such as leading to END CONNECTOR.
Advantage of the present invention and beneficial effect:
1, have excellent sealability and join strength reliably, be fit to very much to have judder and impact than rugged environment and in the very high pipe-line systems such as braking of safety requirement.
2, install simple and conveniently, can carry out dismounting repeatedly, as long as use two spanners just can directly install, need not hank knotting, welding or reaming, not only practiced thrift cost but also safe and reliable, it is convenient especially to keep in repair.
