Abstract
The utility model relates to a kind of efficient slipper seal assembly, comprises O shape circle, and described O shape circle is nested in the groove on valve plug sidewall, the outside of O shape circle is provided with wearing ring, wearing ring is the ring of remaining silent, and internal diameter is less than the external diameter of O shape circle, and the material of described wearing ring is polyflon.The utility model is simple in structure, reasonable in design, and manufacture difficulty is low, and volume is little, arranges succinctly, and sealing is reliable, high temperature resistant, and long service life is not only applicable to the slipper seal of balance valve core formula valve, is applicable to the sealing between other two kinematic pair yet.
Description
Technical field
The utility model relates to a kind of black box, particularly relates to a kind of for the efficient slipper seal assembly on valve valve plug.
Background technique
At present, valve is widely used product in industrial production, and valve can be divided into balance valve core formula valve and non-equilibrium valve core type valve by valve core structure pattern.Its valve plug upper and lower cavity of balance valve core formula valve is communicated with, and the unbalanced force of valve is very little, so the required driving force of this valve is very little, energy-saving and cost-reducing.The shortcoming of this valve is that sealing grade is not high, easily leaks.The key factor that determines this valve performance is the performance of slipper seal assembly.Therefore, be badly in need of a kind of high-quality high-quality slipper seal assembly and meet the product performance requirement that balance valve core formula valve improves day by day.
Summary of the invention
The purpose of this utility model is to overcome the deficiency existing in above-mentioned technology, provides a kind of simple in structure, reasonable in design, and sealing is reliable, and high temperature resistant, long service life, can realize the efficient slipper seal assembly to all kinds of balance valve core type valve seals.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise O shape circle, described O shape circle is nested in the groove on valve plug sidewall, the outside of O shape circle is provided with wearing ring, wearing ring is the ring of remaining silent, internal diameter is less than the external diameter of O shape circle, and the material of described wearing ring is polyflon.
The utility model has the advantages that:
1. simple in structure, reasonable in design, manufacture difficulty is low;
2. volume is little, arranges that succinctly, sealing is reliable, high temperature resistant, long service life;
3. be not only applicable to the slipper seal of balance valve core formula valve, be applicable to the sealing between other two kinematic pair yet.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the A place partial enlarged drawing of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
From Fig. 1-Fig. 2, the utility model comprises O shape circle 3, in described O shape circle 3 grooves 5 that are nested on valve plug 4 sidewalls, the outside of O shape circle 3 is provided with wearing ring 2, wearing ring 2 is the ring of remaining silent, and internal diameter is less than the external diameter of O shape circle 3, and the material of described wearing ring 2 is polyflon.
The utility model can realized all kinds of balance valve core type valve seals, as known in Fig. 1-Fig. 2, in O shape circle 3 grooves 5 that are nested on valve plug 4, with wear-resisting polyflon, being made into wearing ring 2 is nested in same groove, guarantee that wearing ring 2 is positioned at O shape and encloses 3 outsides simultaneously, the degree of depth of valve plug 4 upper grooves 5 be consider the size of O shape circle 3, wearing ring 2 and characteristic and sealing class requirement through calculating and experiment after determine, guarantee sealing and the wear resistance of the utility model black box.Meanwhile, according to the seal request of the medium differential pressure in valve and valve, the quantity of black box of the present utility model have one or several not etc., in Fig. 1, adopted two groups.
It is larger that the utility model O shape is enclosed 3 elasticity, is easily mounted in the groove 5 on valve plug 4.But wearing ring 2, because its material is harder, can become slack after installation, 5 li of grooves, distribute also inhomogeneous, therefore need to, by valve plug 4 rotations, rolling on flat board, wearing ring 2 be smoothed.Reach good slipper seal effect, first the groove depth on valve plug 4 is reasonable in design, and before installing, the internal diameter of O shape circle 3 is less than the external diameter of groove 5 bottoms, and wearing ring 2 internal diameters are less than the external diameter of O shape circle 3 simultaneously, so, after installation, O shape circle 3 will have rational amount of deformation; The internal surface of gland 1 is smooth in addition, and surface roughness should be less than 0.8 μ m.
The utility model simplicity of design, motive sealing are effective, and Applicable media temperature is not more than the occasion of 260 ℃.
