Abstract
The utility model discloses a positive pressure and negative pressure resisting clamp hoop type connection part, which is composed of a pressure self-adaption sealing ring, clamp sleeves and a fastener. The pressure self-adaption sealing ring is designed into a positive pressure and negative pressure resisting structure to be matched with the clamp sleeves, a pair of the clamp sleeves is connected through the fastener to support the pressure self-adaption sealing ring, and accordingly pressure bearing capacity of the connection part is enhanced. By means of matching of the sealing ring, the clamp sleeves and the fastener, the sealing problem of positive pressure and negative pressure industry pipelines is effectively resolved. Furthermore, the connection part is simple in structure. Compared with a traditional flange plate structure, assembling and disassembling speed can be improved by 5 times.
Description
Technical field
The utility model relates to technical field of sealing technology, especially relates to the sealing of positive negative pressure industrial pipeline.
Background technique
Positive negative pressure industrial pipeline is used more and more wider at aspects such as plumbing, pressurized air, oil, coal, mine tailing slurry dust, also more and more stricter and diversified to the seal request of pipeline joint.No matter and existing joint structure pattern is from the how appropriate of pipeline operating mode, or on the convenience of installing/dismounting, all exists the function short slab.Therefore need the appearance of the novel connector structure of a kind of anti-positive negative pressure, convenient disassembly badly.
The model utility content
The purpose of the utility model is to improve the short slab of existing line seal technology; A kind of anti-positive negative pressure clamp band type link is provided; Solve the leakage problem of pipeline, make pipeline under malleation, negative pressure working state, all can reach good sealing effect, improve the operating efficiency of installing, dismantling simultaneously.
A kind of anti-positive negative pressure clamp band type link of the utility model is realized through following technical proposals:
A kind of anti-positive negative pressure clamp band type link, described link comprises the pressure adaptive seal ring, in pairs cutting ferrule and fastening piece; Described fastening piece links together pressure adaptive seal ring and paired card cover.
As preferably, said pressure adaptive seal ring comprises sealing area and negative pressure supporting zone.
As preferably, described cutting ferrule comprises malleation supporting zone and fastening piece attachment areas.
A kind of anti-positive negative pressure clamp band type link of the utility model; Sealing area through the pressure adaptive seal ring seals pipeline, and the malleation supporting zone of negative pressure supporting zone through the pressure adaptive seal ring and cutting ferrule strengthens the sealing effect of pipeline simultaneously; Through fastening piece pressure adaptive seal ring and paired card cover are linked together, form the sealing system of pipeline joint, so link is simple in structure, be convenient to installation, convenient disassembly, significantly improve operating efficiency.
Description of drawings
Through embodiment, the utility model is further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is a cutting ferrule structural representation among Fig. 1;
Fig. 4 is a pressure adaptive ring structure schematic representation among Fig. 1;
Fig. 5 is the sectional view that the utility model is connected with pipeline.
1 is cutting ferrule, and 2 is the pressure adaptive seal ring, and 3 is fastening piece, and 4 is pipeline, and 5 is the malleation supporting zone, and 6 is the fastening piece attachment areas, and 7 is the negative pressure supporting zone, and 8 is sealing area.
Embodiment
In Fig. 1, a kind of anti-positive negative pressure clamp band type link comprises pressure adaptive seal ring 2, paired cutting ferrule 1 and cutting ferrule 1 coupled together and with pressure adaptive seal ring 2 fixed fastening parts 3.
In Fig. 5, the utility model is connected with pipeline 4, and in Fig. 4,4 of the sealing area 8 of pressure adaptive seal ring 2 and pipelines form sealing system.When pipeline 4 internal pressures changed, seal ring 2 relied on the elasticity adjustment of self and the cooperation of cutting ferrule 1, remained the sealability of whole system.When pipeline 4 operating modes were negative pressure, pressure adaptive seal ring 2 exclusive negative pressure supporting zones 7 provided support for the line seal system, to guarantee the sealing of pipeline 4; When pipeline 4 operating modes were malleation, in Fig. 3, the malleation supporting zone of cutting ferrule 15 provided support for pressure adaptive seal ring 2, and protection seal ring 2 is not destroyed by high pressure, to guarantee the sealing of pipeline 4.
In Fig. 3, only need the fastening piece attachment areas 6 of fastening piece 3 through cutting ferrule 1, just can the utility model be connected with pipeline 4, form sealing system.Therefore the utility model is simple in structure, is convenient to installation, convenient disassembly, significantly improves operating efficiency.
The foregoing description; It is an instance of the utility model; Be not enforcement and the interest field that is used for limiting the utility model, all and the said same content of the utility model claim or the technological scheme that is equal to all should be included in the utility model protection domain.
