Abstract
The utility model discloses a kind of valve seat soft sealing structure, comprising: valve body, spheroid, O type circle, seal ring, trim ring, spring, seat ring; Described O type circle is positioned at outside seat ring; Described seal ring is positioned at inside seat ring; Described trim ring is wrapped in whole sealing configuration and has reserved bound edge; Described spring is between trim ring and seat ring.The utility model simplicity of design, for the improvement of modular construction and material, ensures that valve seat there will not be obscission, and adapts to the industries such as high temperature resistant, high pressure and burn into wearing and tearing, uses repeatedly still can keep sealing effect at valve.
Description
Technical field
The utility model relates to valve field, is specifically related to a kind of valve seat soft sealing structure.
Background technique
Soft sealing structure is used for realizing pipe-line system cuts off and the parts of flow control as a kind of, and obtain applying very widely in many fields such as oil, chemical industry, metallurgy, water power, in the prior art, its sealing material is rubber, teflon etc.Due to the restriction of structure characteristic, be not suitable with high temperature resistant, high pressure and corrosion-resistant, the industry such as to resistance to wear.In use, after there is switch tens times for this valve, spheroid and valve base surface abrade and leak needs and change and the problem such as the life-span is short, be studied and improve sealing configuration.
Model utility content
the technical problem that model utility will solve
The purpose of this utility model is to overcome above-mentioned technical deficiency, provide a kind of valve seat soft sealing structure of simplicity of design, for the improvement of modular construction and material, ensure that valve seat there will not be obscission, and adapt to the industries such as high temperature resistant, high pressure and burn into wearing and tearing, use repeatedly at valve and still can keep sealing effect.
technological scheme
For achieving the above object, the technological scheme that the utility model provides is:
A kind of valve seat soft sealing structure of the present utility model, comprising: valve body, spheroid, O type circle, seal ring, trim ring, spring, seat ring;
Described O type circle is positioned at outside seat ring;
Described seal ring is positioned at inside seat ring;
Described trim ring is wrapped in whole sealing configuration and has reserved bound edge;
Described spring is between trim ring and seat ring.
Further technological scheme, the material of described seat ring is metal.
Further technological scheme, the material of described seal ring is polyether-ether-ketone.
beneficial effect
The technological scheme adopting the utility model to provide, compared with prior art, has following beneficial effect:
1, in the application, trim ring is wrapped in whole sealing configuration and has reserved bound edge, ensures that valve seat there will not be obscission.
2, in the application, the material of seat ring is metal, avoids and uses the material such as rubber, teflon to cause perishable.
3, in the application, the material of seal ring is polyether-ether-ketone, can meet after high temperature condition lower valve repeatedly uses and not easily be softened.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of valve seat soft sealing structure.
Embodiment
For understanding content of the present utility model further, in conjunction with the accompanying drawings and embodiments the utility model is described in detail.
Embodiment
As shown in Fig. 1, a kind of valve seat soft sealing structure of the present embodiment, comprising: valve body 1, spheroid 7, O type circle 2, seal ring 3, trim ring 4, spring 5, seat ring 6; O type circle 2 is positioned at outside seat ring 6; Seal ring 3 is positioned at inside seat ring 6;
Trim ring 4 is wrapped in whole sealing configuration and has reserved bound edge, ensures that valve seat there will not be obscission; Spring 5 is between trim ring 4 and seat ring 6.The material of seat ring 6 is metals, corrosion-resistant.The material of seal ring 3 is polyether-ether-ketones, can meet after high temperature condition lower valve repeatedly uses and not easily be softened.
Schematically above be described the utility model and mode of execution thereof, this description does not have restricted, and also just one of the mode of execution of the present utility model shown in accompanying drawing, actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the utility model and creating aim, design the mode of structure similar to this technological scheme and embodiment without creationary, protection domain of the present utility model all should be belonged to.
