Abstract
The invention discloses a soft sealing structure for a valve seat. The soft sealing structure for the valve seat comprises a valve body, a ball, an O-shaped ring, a sealing ring, a pressing ring, a spring and a valve seat ring, wherein the O-shaped ring is located on the outer side of the valve seat ring, the sealing ring is located on the inner side of the valve seat ring, the whole sealing structure is wrapped in the pressing ring, and a covered edge is reserved; the spring is located between the pressing ring and the valve seat ring. The soft sealing structure for the valve seat is simple in design, the structures and materials of components are improved, it is guaranteed that the valve seat does not fall, the soft sealing structure can be suitable for high-temperature-resistant, high-pressure-resistant, corrosion-resistant and abrasion-resistant industries, and the sealing effect can be still kept after a valve is used repeatedly.
Description
Technical field
The present invention relates to valve field, be 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.
Summary of the invention
the technical problem that invention will solve
The object of the invention 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, technological scheme provided by the invention is:
A kind of valve seat soft sealing structure of the present invention, 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
Adopt technological scheme provided by the invention, compared with prior art, there is 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 invention further, the present invention is described in detail in conjunction with the accompanying drawings and embodiments.
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 present invention and mode of execution thereof, this description does not have restricted, and also just one of the embodiments of the present invention 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 invention aim, designing the mode of structure similar to this technological scheme and embodiment without creationary, all should protection scope of the present invention be belonged to.
