Abstract

The utility model relates to a pipe joint mainly comprising a joint body, a fastening ring, a claw, a push sleeve, an opening sleeve and a seal sleeve. The utility model is characterized in that the seal sleeve encircles the excircle of the pipe and the inner convex ring of the seal sleeve is positioned at the two end ports of the pipe. The fastening ring can be screwed to push the claw to make the taper sleeve stress tightly the opening sleeve and wrap tightly the seal sleeve thus to reach the effect of sealing the pipe. Meanwhile, the claw can stick firmly the pipe and push the pipe in the axial direction. The end port of the pipe and the convex ring of the seal sleeve are closely attached together. The utility model with a fine seal and leakage proof performance is very convenient to assemble and disassemble.

Description

Pipe joint

The utility model relates to liquid, gas piping field, says so and be applicable to a kind of pipe fitting joint that liquid, gas piping are installed in tool this locality.

In the prior art, small-bore pipeline erection joint also all is to adopt inipple to connect, and the head of pipe fitting will be pulled the system screw thread; What the heavy caliber pipeline was taked is: joint socket connects, modes such as flange plate connection or counterpart welding, and people are accustomed to using these methods for a long time, and advantage of having nothing in common with each other and deficiency use some inconvenience always, and be also more time-consuming.

The purpose of this utility model provides a kind of pipe fitting joint of easy loading and unloading.

Scheme of the present utility model is achieved in that pipe fitting joint mainly is made up of fittings body, collar, stuffing box gland, claw, tapered sleeve and opening sleeve.Be provided with the leak proof seal cover in the fittings body, stuffing box gland surrounds the cylindrical of pipe fitting, be provided with bulge loop in the stuffing box gland and place between the two pipe fittings, opening sleeve is enclosed within on the stuffing box gland, and taper sheath is placed between opening sleeve and the fittings body, the awl circle that opening sleeve external diameter two ends are processed into awl circle and tapered sleeve respectively fits, but slide relative, claw inner end and tapered sleeve join, and claw male cone (strobilus masculinus) and fittings body inner conical surface fit slidably, in the fittings body port internal thread is arranged, collar is screwed into the inner end and the claw end face joins.Turn collar during installation and promote claw, tapered sleeve moves inwards, opening sleeve be subjected to tapered sleeve radially the pressurized diameter receive and hold stuffing box gland for a short time tightly, internal diameter was received for a short time when tapered sleeve was mobile inwards, tightened pipe fitting simultaneously and moved axially, and withdrawed from after stoping pipe fitting stressed.

Advantage of the present utility model: simple in structure, good airproof performance, convenient during installation, maintenance, improved work efficiency.

Fig. 1 is the general structure view of the utility model pipe joint;

Fig. 2 is the utility model pipe joint split shed nested structure view;

Fig. 3 is a claw structure view in the utility model pipe joint;

Fig. 4 is another embodiment's general structure view of the utility model pipe joint.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 shows the general structure of the utility model pipe joint, stuffing box gland (6) is contained on the pipe fitting (7) of two butt joints, bulge loop in the stuffing box gland (6) places between the two pipe fittings (7), opening sleeve (5) is enclosed within stuffing box gland (6) and is placed in the fittings body (2), tapered sleeve (4) inner conical surface pastes mutually with the male cone (strobilus masculinus) of opening sleeve (5), circle joins in tapered sleeve (4) cylindrical and the fittings body (2), the inner end of three claws (3) and tapered sleeve (4) join, the interior curved tooth of claw (3) and pipe fitting (7) join, and collar (1) is screwed into that interior edge face and claw (3) join in the internal thread of fittings body (2) port.Rotation collar (1) direct-axis line promotes claw (3) and tapered sleeve (4), tapered sleeve (4) is received opening sleeve (5) diameter and is held stuffing box gland (6) for a short time tightly, stuffing box gland (6) is close to pipe fitting (7) cylindrical, claw (3) move inward be subjected to fittings body (2) inner conical surface restriction diameter to receive the tight pipe fitting of little length (7) simultaneously but move axially the bulge loop of top tight sealing cover (6).

Fig. 2 shows the structure of the opening sleeve in the utility model.Opening sleeve (5) has groove mouth (8).

Fig. 3 shows the structural drawing of claw in the utility model (3).Three parts of incisions of claw (3) five equilibrium, claw (3) intrados is processed with tooth (9).

Fig. 4 is another embodiment's of the utility model a general structure.When large diameter pipe fitting was installed, fittings body (2) taked flange plate to be connected with collar (1), and screw (10) passes the hole in the collar (7), is screwed into the screw of fittings body (2), and collar (1) inner end can promote claw (3) and move inwards.

Claims

1, a kind of pipe joint, mainly by fittings body, collar, stuffing box gland, claw, pushing sleeve and opening sleeve are formed, it is characterized in that: stuffing box gland (6) surrounds the cylindrical of pipe fitting (7), stuffing box gland is provided with bulge loop in (6), opening sleeve (5) is enclosed within on the stuffing box gland (6), opening sleeve (5) external diameter two push away the circle and pushing sleeve (4) slide relative places fittings body (2) but the inner cone circle fits, claw (3) inner end and tapered sleeve (4) join, claw (3) male cone (strobilus masculinus) with fittings body (2) but inner conical surface pastes slide relative mutually, the end face that collar (1) is screwed into fittings body (1) port inner end and claw (3) joins.

2, pipe joint according to claim 1 is characterized in that: claw (3) intrados is processed with tooth (9).
