Description
Technical field
The utility model is specifically related to a kind of water-tight equipment, particularly a kind of seal ring.
Background technique
Along with the progress of science and technology, every profession and trade development constantly promotes, and the also steady-state growth of mechanical seal industry, seal ring market also presents the situation updated.Each enterprise constantly strengthens product technology and upgrades, and improves production capacity further, the supply market demand.But seal ring majority is all rubber material to be made, although rubber be sealing good material, easy to wear, easily aging, belong to easily damaged parts, often need to change, due to, seal ring is generally in the most crucial portion of machinery, change difficulty very large, especially some complex device.
The seal ring of prior art, change again after generally all needing detaching equipment, but market also starts to occur that some can not be dismantled, also the seal ring can changed, but what but easily occur the seal ring after changing fixedly occurs the problem not tight with machinery cooperation, easily occur that lubricant oil spills and foreign object invades.
Summary of the invention
The utility model provides the whole of a kind of fast changeable to cut open dual-purpose seal ring, and object solves prior art problem, reaches fast changeable and sealing object more closely.
The utility model deal with problems adopt technological scheme be:
The whole of a kind of fast changeable cuts open dual-purpose seal ring, be made up of seal ring body, shoulder, bizet, waist, dust excluder lips, sealing lip, spring groove and spring, described shoulder is positioned on the excircle of seal ring body, described bizet and waist are positioned on the inner circumference of seal ring body, described sealing lip is positioned on bizet inner circumference, described bizet excircle is provided with spring groove, spring is provided with in described spring groove, described dust excluder lips is positioned on waist inner circumference, it is characterized in that: described shoulder excircle is provided with to move back and pulls out gradient.
Reinforcement metal circle is provided with in described shoulder.
Described seal ring is split type integrative-structure, and seal ring termination is provided with guiding jack, another termination of seal ring is provided with pin.
Described shoulder excircle is provided with the horizontal sextant angle that moves back and pull out gradient between 0 degree to 90 degree.
The beneficial effects of the utility model: cuing open dual-purpose sealing configuration due to a kind of fast changeable of the utility model whole is split type integrative-structure, quick-replaceable seal ring under mechanical prerequisite can not dismantled, simultaneously pull out gradient because the shoulder excircle of seal ring is provided with to move back, when being installed to mechanically, due to the effect split surface of axial force and seal ring with outer weekly assembly more and more tightr, good sealing effect, due to be provided with in seal ring with outer week move back pull out gradient when dismantling more easily, quick, effectively alleviate workman's workload.
