Abstract

The utility model relates to a pipe joint for solving the problem of load transfer, particularly a load transfer joint which comprises a body, a sealing ring, a gland bush, a stub pipe, a flange, nuts and long screw studs, wherein each of the long screw studs is of full thread and the body is provided with a flanged disc and an outer sleeve part integrated with the flanged disc. The utility model is characterized in that the stub pipe is welded with the flange and is provided with the sealing ring and the gland bush which presses the sealing ring, and one end of the stub pipe is inserted in the outer sleeve part of the body, and is pressed by the sealing ring and the gland bush through compression nuts; the body, the gland bush and the flange are respectively provided with corresponding threaded holes which are evenly distributed according to circumference, and the long screw studs are penetrated in the threaded holes and are locked by the nuts. The utility model is used for pipe connection.

Description

Force transmission joint

The utility model relates to pipe joint, refers in particular to a kind of can being in operation and end thrust is passed to the pipe joint of whole pipe.Be to be applicable to that pipelines such as carrying water, oil, gas and particle powdery medium is connected the joint of usefulness with equipment such as pump, valves.

The Placement of equipment such as existing pump, valve and pipeline, generally be directly to connect by flange, this Placement needs more accurate installation dimension, and just being guaranteed, it is intact to connect, so just improved construction requirement greatly, and after operation a period of time, need dismounting or maintenance, owing to be subjected to the influence of internal stress, pump, valve arrangement may be difficult to remove, thereby have improved labor intensity greatly; Another mode is equipment and the expansion joints of pipeline enclosure dress such as pump, valve, though this mode can remedy the defective of above-mentioned Placement, but produced other problem, be equipment such as pump, valve when opening or closing, can produce very big end thrust, and adorn after the expansion joint, here just become breakpoint, so just increased the axial strength of equipment such as pump, valve greatly, thereby influenced its work, even suffered damage.

The purpose of this utility model provides a kind of force transmission joint; its is provided convenience to the installation, maintenance of equipment such as main pipe and pump, valve on the one hand; reduce labor intensity; raise the efficiency; be to be in operation end thrust is passed to whole pipe on the other hand; alleviate the axial strength of equipment such as pump, valve, play the certain protection effect.

The purpose of this utility model is achieved in that force transmission joint, it comprises body, seal ring, gland, short tube, flange, nut and long threaded rod, long threaded rod is a Full Thread FT, contain on the body flange plate and with the outer race section of its one, it is characterized in that: weldering is provided with flange and is provided with seal ring and pushes down the gland of seal ring on the short tube; Short tube one weak point inserts the outer race section of body and is pushed down by gland nut by seal ring, gland; Body, gland and flange are respectively equipped with the corresponding screw that wears long threaded rod by the circumference five equilibrium, and long threaded rod is arranged in these screws and is pinned by nut.

Above-mentioned design; the short tube that is welded with flange inserts in the body, and certain displacement amount is arranged, and pushes down seal ring by gland; make its sealing; by the Full Thread FT long threaded rod flange of equipment such as the flange on the short tube and pump, valve is fixed again, made its one-tenth as a whole, so just realized when installation and maintenance; can adjust according to on-the-spot installation dimension; when work, can be passed to whole pipe to end thrust, equipment such as pump, valve are played certain protective role.

Below by drawings and Examples the utility model is described further again:

As Figure 1-3, the utility model comprises body 1, seal ring 2, gland 3, short tube 4, flange 5, nut 6 and long threaded rod 7, long threaded rod 7 is a Full Thread FT, contain on the body 1 flange plate and with the outer race section 8 of its one, it is characterized in that: weldering is provided with flange 5 and is provided with seal ring 2, pushes down the gland 3 of seal ring on the short tube 6; Short tube 4 one weak points insert the outer race section 8 of bodies 1 and are pushed down by gland nut 9 by seal ring 2, gland 3; Body 1, gland 3 and flange 5 are respectively equipped with the corresponding screw that wears long threaded rod 7 by the circumference five equilibrium, and long threaded rod 7 is arranged in these screws and is pinned by nut 6.Wherein, flange 5 is positioned at short tube 4 ends.Its Placement is that both sides all are that flange connects.Can be described as two flange force transmission joints.(VSSJSF type)

Shown in Fig. 4,5, wherein, flange 5 is positioned at short tube 4 middle parts, and the short tube end is used to weld.Its Placement is to be that flange connects on one side, and another side is welding.Can be described as single-flange force transmission joint.(VSSJAFG type)

Shown in Fig. 6,7, wherein, flange 5 is positioned at short tube 4 middle parts, and the short tube end also is provided with flange 10.Its Placement is that both sides all are that flange connects.Be specially adapted to the narrow place of installing space.Can be described as removable pair of flange force transmission joint.(VSSJAFC)

These force transmission joints can use spheroidal graphite cast iron, carbon steel, alloyed steel, stainless steel and other metal materials to make seal ring nitrite rubber, material such as fluorine rubber according to different use occasions.
