Abstract

The invention discloses a length-adjustable pipe connector which comprises a pipe connector outer body and a pipe connector inner core, wherein the pipe connector outer body is of a circular hollow structure; an inward-convex shoulder is arranged on the inner wall of the lower end of the pipe connector outer body; an inner thread is arranged on the inward-convex shoulder; an outer body flange disc is arranged on the excircle of the upper end of the pipe connector outer body; the pipe connector inner core is of a circular hollow structure; an outer thread is arranged on the excircle of the pipe connector inner core; an inner core flange disc is arranged at the lower end of the pipe connector inner core; and depending on the interaction between the inner thread and the outer thread, the pipe connector outer body and the pipe connector inner core are connected. The length-adjustable pipe connector disclosed by the invention has the advantage that the pipe connector length can be adjusted within a certain range, and can replace the practice that the pipe connector length is adjusted by adding a plurality of gaskets, thereby enhancing the sealing property and the mechanical strength of the connecting position of the length-adjustable pipe connector; and meanwhile, the mounting is simple, convenient and rapid, and the human cost is reduced.

Description

A kind of pipe joint of adjustable length

Technical field

The present invention relates to field of chemical equipment, more particularly to a kind of pipe joint of adjustable length.

Background technology

In chemical mechanical equipment field, generally laying pipeline is needed according to different, pipe joint is requisite zero One of part, can be the connection that can be dismounted between the fastening means, or element and pipeline between pipeline and pipeline Point, act as in the tube indispensable key player；Although existing pipe joint has become standard component, different series Have been able to produce in batches and sell with the pipe joint of different length；But special case always occurs in practical application, The pipe joint of particular length size is needed, is that this generally increases multiple liners in the flange side surface of pipe joint, increased with reaching The purpose of pipe joint length, but while the sealing property and mechanical strength that also result at pipe joint decline, and installation is also compared It is cumbersome.

The content of the invention

The invention mainly solves the technical problem of at present for increase the length of pipe joint and at the ring flange end of pipe joint Face increases multiple liners, but while the sealing property and mechanical performance that also result in joint decline, and installation is comparatively laborious Problem.

To solve above-mentioned technical problem, one aspect of the present invention is：A kind of pipe of adjustable length is provided Joint, including pipe joint ectosome, pipe joint inner core, it is characterised in that the pipe joint ectosome be circular hollow structure, the pipe The inwall of joint ectosome lower end is provided with convex shoulder, and the convex shoulder is provided with internal thread, the upper end of the pipe joint ectosome It is cylindrical to be provided with ectosome ring flange；The pipe joint inner core is circular hollow structure, and the cylindrical of the pipe joint inner core is provided with outer spiral shell Line, the lower end of the pipe joint inner core is provided with inner core ring flange；The pipe joint ectosome is with the pipe joint inner core by described Internal thread cooperates to be connected with externally threaded.

Further, the pipe joint of described a kind of adjustable length, also including locking nut, the locking nut is arranged In the cylindrical of the pipe joint inner core；Further, also set up on a kind of ectosome of the pipe joint of described adjustable length Spanner bayonet socket, the spanner bayonet socket is to be symmetrical arranged；Further, the spanner of the pipe joint of described a kind of adjustable length Bayonet socket is two pairs, is uniformly distributed circumferentially.

Further, the pipe joint of described a kind of adjustable length, the inner core ring flange of the pipe joint inner core is can Rotate in a circumferential direction and move axially, the lower end of the pipe joint inner core also includes inner core flange shoulder.

Further, the pipe joint of described a kind of adjustable length, also including sealing gasket, the sealing gasket is arranged at institute State between convex shoulder and the locking nut.

The invention has the beneficial effects as follows：A kind of pipe joint of adjustable length that the present invention is pointed out, can be in certain model The length of interior regulation pipe joint is enclosed, can be substituted using the multiple liners of increase come the way of regulation pipe joint length so that pipe connects The sealing property and mechanical strength of the joint of head is strengthened, while simple installation is quick, saves human cost.

Description of the drawings

Technical scheme in order to be illustrated more clearly that the embodiment of the present invention, below will be to making needed for embodiment description Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for For those of ordinary skill in the art, on the premise of not paying creative work, can be obtaining other according to these accompanying drawings Accompanying drawing, wherein：

Fig. 1 is a kind of structural representation of a preferred embodiment of the pipe joint of adjustable length of the invention；

Mark in accompanying drawing for：1st, pipe joint ectosome；11st, convex shoulder；111st, internal thread；12nd, ectosome ring flange；13rd, spanner Bayonet socket；2nd, pipe joint inner core；21st, external screw thread；22nd, inner core ring flange；23rd, inner core flange shoulder；3rd, locking nut；4th, sealing gasket.

Specific embodiment

The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described enforcement Example is only a part of embodiment of the present invention, rather than the embodiment of whole.Based on the embodiment in the present invention, this area is common All other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model of present invention protection Enclose.

Fig. 1 is referred to, the embodiment of the present invention includes：Pipe joint ectosome 1, pipe joint inner core 2, the pipe joint ectosome 1 is Circular hollow structure, the inwall of the lower end of pipe joint ectosome 1 is provided with convex shoulder 11, and the convex shoulder 11 is provided with internal thread 111, the cylindrical of the upper end of the pipe joint ectosome 1 is provided with ectosome ring flange 12；The pipe joint inner core 2 is circular hollow knot Structure, the cylindrical of the pipe joint inner core 2 is provided with external screw thread 21, and the lower end of the pipe joint inner core 2 is provided with inner core ring flange 22；Institute State pipe joint ectosome 1 and the pipe joint inner core 2 by the internal thread 111 and external screw thread 21 cooperate to be connected.

Further, the pipe joint of described a kind of adjustable length, also including locking nut 4, the locking nut 4 sets The cylindrical of the pipe joint inner core 2 is placed in, rotational lock nut 3 can lock the entirety of pipe joint to press convex shoulder 11 Length, and improve the mechanical strength and sealing property of pipe joint；Further, a kind of pipe of described adjustable length connects Spanner bayonet socket 13 is also set up on the ectosome of head, the spanner bayonet socket 13 sticks into spanner bayonet socket to be symmetrical arranged using open-end wrench 13, can press and convex shoulder 11 in order to locking nut 3, further, a kind of pipe joint of described adjustable length Spanner bayonet socket 13 be two pairs, be uniformly distributed circumferentially, to meet the needs of narrow and small occasion.

Further, to rotate in a circumferential direction and move axially, the pipe connects the inner core ring flange 22 of the pipe joint inner core 2 The lower end of head inner core 2 also includes inner core flange shoulder 23, by the inner core ring flange 22 that rotates in a circumferential direction, can adjust inner core ring flange 22 The position of installing hole.
