It is used.
Existing pipe joint has many kinds.Existing pipe joint common problem be pipe upon connection, pipe and joints
It is not firm to connect, and there is axial dipole field between pipe and joint.Simultaneously after pipe joint is using a period of time, due to expanding with heat and contract with cold
In the presence of pipe and joint the normal transport of medium loosening, impact pipeline in occurs.
As can be seen here, current pipe joint has that connection is not firm, easily loosens.
Utility model content
Technical problem to be solved in the utility model is that current pipe joint exists and connects not firm, asking of easily loosening
Topic.
In order to solve above-mentioned technical problem, this utility model be employed technical scheme comprise that to provide a kind of high fastness
Pipe pipe joint, including：
Fixed cover, is arranged on the lateral surface of body, two ends are provided with step,
Seal stopper ring, is removably attached on the lateral surface of described fixed cover, one end of described seal stopper ring is inwardly prolonged
Stretch formation back-up ring, the lateral surface of described step, the medial surface of described back-up ring and described body forms sealing space, and described sealing is empty
Between be provided with sealing ring, the lateral surface of described back-up ring is resisted against on the boss of described body,
Gland, is arranged on described seal stopper ring and the lateral surface of described body, and is stuck in described boss away from described gear
The side of circle.
In such scheme, the lateral surface of described fixed cover is interval with two threaded portions, and the number of described seal stopper ring is
Two, described seal stopper ring passes through to screw to correspond with described threaded portion to be fixed.
In such scheme, described gland is sequentially provided with fixed part, holding section and compressed part, the inner side of described compressed part
The outer circumference surface of face and described seal stopper ring agrees with, and the outer peripheral face of described holding section and described body agrees with, on described fixed part
Bolt is installed, described holding section is symmetricly set on the both sides of described compressed part, and is stuck in described boss away from described back-up ring
Side, described fixed part is symmetricly set on the outside of described holding section.
In such scheme, between described holding section and described compressed part, it is provided with the transition conical surface.
In such scheme, described gland is combined by two semicylindrical half glands, and described in two, half gland passes through
Fastening bolt is fixed.
This utility model, seal stopper ring is arranged on the outer circumference surface of protective case using the mode of being detachably fixed, and both avoids
The relative slip with protective case for the seal stopper ring, can set its firmness by manual assembly again, be difficult to loosen it is ensured that intact
Sealing and fastness.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of fixed cover of the present utility model；
Fig. 3 is the structural representation of seal stopper ring of the present utility model；
Fig. 4 is the structural representation of gland of the present utility model.
Specific embodiment
With reference to specific embodiment and Figure of description, this utility model is described in detail.
As shown in Figure 1, Figure 2 and Figure 3, the pipe pipe joint of the high fastness that this utility model provides includes fixed cover 1, sealing
Baffle ring 3 and gland 4.Fixed cover 1 is arranged on the lateral surface of body 5, and two ends are provided with step 11, and seal stopper ring 3 is removably solid
It is scheduled on the lateral surface of fixed cover 1, one end of seal stopper ring 3 extends inwardly to form back-up ring 31, step 11, the medial surface of back-up ring 31
Form sealing space with the lateral surface of body 5, sealing space is provided with sealing ring 2, and the lateral surface of back-up ring 31 is resisted against the convex of body 5
On platform 51, gland 4 is arranged on seal stopper ring 3 and the lateral surface of body 5, and is stuck in the side away from back-up ring 31 for the boss 51.
Seal stopper ring 3 is removably attached to the outside of fixed cover 1, and seal stopper ring 3 extend back-up ring 31, step
11st, the lateral surface of the medial surface of back-up ring 31 and fixed cover 1 forms sealing space, and the fluid being prevented effectively from body 5 overflows, sealing
Property good, the relative slip being detachably fixed mode, both having avoided seal stopper ring 3 and protective case 1 of seal stopper ring 3, can lead to again
Remarkable frock arranges its firmness fixed, is difficult to loosen it is ensured that intact sealing and fastness.
Preferably, the lateral surface of fixed cover 1 is interval with two threaded portions 12, and the number of seal stopper ring 3 is two, sealing gear
Ring 3 is corresponded with threaded portion 12 and fixes.Staff just can be installed it is not necessary to by other instruments, and adjustable tightness.
Preferably, as shown in figure 4, fixed part 41, holding section 42 and compressed part 43, compressed part 43 are sequentially provided with gland 4
Medial surface agree with the outer circumference surface of seal stopper ring 3, the outer peripheral face of holding section 42 and body 5 agrees with, and fixed part 41 is installed
There is bolt, holding section 42 is symmetricly set on the both sides of compressed part 43, and be stuck in the side away from back-up ring 31 for the boss 51, fixed part 41
It is symmetricly set on the outside of holding section 42.The effect of compressed part 43 is compression seal stopper ring 3, and then plays sealing and fastening work
With holding section 42 is used for agreeing with body 5, it is to avoid occur relatively to slide.
Preferably, it is provided with the transition conical surface between holding section 42 and compressed part 43, structure is more compact.
Preferably, gland 4 is combined by two semicylindrical half glands 4, and it is solid that two halves gland 4 passes through fastening bolt
Fixed, combine the frame mode installed, be more convenient to adjust the tightness of gland 4, convenient handling.
This utility model, seal stopper ring is arranged on the outer circumference surface of protective case using the mode of being detachably fixed, and both avoids
The relative slip with protective case for the seal stopper ring, can set its firmness by manual assembly again, be difficult to loosen it is ensured that intact
Sealing and fastness.
This utility model is not limited to above-mentioned preferred forms, and anyone should learn under enlightenment of the present utility model
The structure change made, every have same or like technical scheme with this utility model, each falls within guarantor of the present utility model
Within the scope of shield.
