Abstract
The utility model relates to a clamp union sealing element comprising an elastomeric sealing ring. A metal stop collar is built in the elastomeric sealing ring. The metal stop collar is provided on the outer periphery of the elastomeric sealing ring. With the metal collar built in the elastomeric sealing ring, all the force from the locking nut of the clamp is applied to the metal stop ring. That is the thickness of the metal stop ring determines the maximum amount of compression of the elastomeric sealing ring. As a result, the elastomeric sealing ring is protected and the service life of the sealing ring is prolonged.
Description
Technical field
The utility model relates to seal element, relates in particular to the Sealing of the sanitation-grade clamp band type loose joint of the standards such as the SMS standard that is applied to ISO 2037 and DIN 11850.
Background technique
The yoke configurations of prior art as shown in Figure 1, it side that comprises two semi-rings, 3, two semi-rings 3 connects with hinge 6, opposite side connects by bolt 7, and with locknut 4 turn bolts 7, to adjust the degree of blocking of two semi-rings 3.Offer the groove 31 of the flange of containing tube end of body in the semi-ring 3.
During use, flange splicing with two clip loose joints, accompany seal washer between two flanges, the conventional seals packing ring that uses at present, realize sealing with the locknut 4 press seal packing rings on the clip, but the degree of tightening locknut 4 bolts 7 can't be carried out spacing control, and is excessively loose, can't guarantee that clip has compressed seal washer; Tension, easily damage seal washer by pressure, and after being screwed to a certain degree, the seal compression gap that the seal compression of locknut 4 sides is compared hinge 6 sides can strengthen gradually, cause the sealability of whole sealing plane relatively uneven, therefore can't guarantee at whole sealing surface effective sealing.
The model utility content
The purpose of this utility model is to provide a kind of clip loose joint Sealing, and it can solve the problem that seal compression is difficult to carry out effective and reasonable control.
In order to achieve the above object, the technological scheme that adopts of the utility model is as follows:
Clip loose joint Sealing, it comprises elastic seal ring, described elastic seal ring is built-in with a metal spacing ring.
Preferably, described metal spacing ring is positioned on the excircle of elastic seal ring.
Preferably, in order to improve the sealability of elastic seal ring and flange, be provided with the o V-shaped ring on the both ends of the surface of elastic seal ring.Described o V-shaped ring is positioned on the inner circumference of elastic seal ring.
Preferably, be provided with the ring-type coated side on the side end face of elastic seal ring, described ring-type coated side is positioned on the outer periphery of elastic seal ring.Fixing hoop loose joint Sealing when described ring-type coated side is used for installing.
Preferably, described elastic seal ring is rubber ring.
The utlity model has following beneficial effect:
In elastic seal ring, be provided with the metal spacing ring; even the locknut of clip is used large power again; the capital is applied on the metal spacing ring; it is the maximum seal compression that the thickness of metal spacing ring has determined elastic seal ring; thereby elastic seal ring has been played protective action, prolonged the working life of elastic seal ring.
Description of drawings
Fig. 1 is the structural representation of the clip of prior art;
Fig. 2 is the sectional view of the clip loose joint Sealing of the utility model preferred embodiment;
Fig. 3 is the application schematic diagram of the clip loose joint Sealing of the utility model preferred embodiment.
Reference character: 1, elastic seal ring; 11, o V-shaped ring; 12, ring-type coated side; 2, metal spacing ring; 3, semi-ring; 31, groove; 4, locknut; 6, hinge; 7, bolt; 100, clip loose joint; 101, flange; 200, clip loose joint; 201, flange.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
As shown in Figure 2, clip loose joint Sealing, it comprises elastic seal ring 1, described elastic seal ring 1 is built-in with a metal spacing ring 2.The elastic seal ring 1 of the present embodiment adopts rubber ring.Metal spacing ring 2 sulfides with elastic seal ring 1.Because metal spacing ring 2 is built in the elastic seal ring 1, therefore, the natural thickness H1 of elastic seal ring 1 is greater than the thickness H2 of metal spacing ring.
The metal spacing ring 2 of the present embodiment is positioned on the excircle of elastic seal ring 1.
Be provided with o V-shaped ring 11 on the both ends of the surface of elastic seal ring 1.Described o V-shaped ring 11 is positioned on the inner circumference of elastic seal ring 1.
Also be provided with ring-type coated side 12 on one side end face of elastic seal ring 1, described ring-type coated side 12 is positioned on the outer periphery of elastic seal ring 1.
In conjunction with Fig. 1 to Fig. 3, the using process of the present embodiment is as follows:
The flange 101 of clip loose joint 100 is docked with the flange 201 of clip loose joint 200; place the clip loose joint Sealing of the present embodiment between flange 101 and the flange 201; then block flange 101 with clip; the outer periphery of flange 201; make flange 101; the outer periphery of flange 201 are embedded in the groove 31 of clip; and the ring-type coated side 12 of clip loose joint Sealing places groove 31 and flange 101; between the outer periphery of flange 201; with locknut 4 locking hoops; the flange 101 of compressing clip loose joint; flange 201 produces axial relatively close displacement; pressure elasticity seal ring 1 is from H1 to H2; realize spacing; can effectively control H3; the value of H4 is within zone of reasonableness; realize rationally sealing; afterwards no matter in the great power of locknut 4; the capital is pressed on the metal spacing ring 2; elastic seal ring 1 is played protective action, prolonged its working life.
For a person skilled in the art, can make other various corresponding changes and distortion according to technological scheme described above and design, and these all changes and distortion should belong within the protection domain of the utility model claim all.
