Abstract
The utility model provides an eccentric valve. The eccentric valve comprises a valve body, a valve element, a bottom shaft, a valve rod, a vale base and a pressing ring, the valve element is arranged in the valve body, the upper end of the valve element is connected with the valve rod, the lower end of the valve element is connected with the valve body through the bottom shaft, a spherical crown of the valve element is attached to the valve base, the valve base is fixed to the valve body through the pressing ring, and the eccentric valve is characterized in that the opposite side faces of the valve base and the valve element are respectively provided with a wear-resisting layer, the pressing ring is composed of two or more pressing ring pieces, the opposite side faces of the valve base and the valve element are provided with the wear-resisting layers, and the wear-resisting layers are made of stainless steel materials and can prevent the contact face of the valve element and the valve base from being abraded. According to the eccentric valve, the good sealing performance can be kept for a long time, the service life is prolonged, the pressing ring is composed of the pressing ring pieces, each pressing ring piece can be independently adjusted, it is ensured that the valve base can be fixed to the valve body well, and the sealing performance between the valve base and the valve body is improved.
Description
Technical field
The utility model belongs to valve technology field, relates in particular to a kind of eccentric valve.
Background technique
At present domestic and international metal sealed eccentric valve, valve body and valve seat is substantially all bulk metal casting, the valve seat of this structure, produce installation relatively all relatively simple, but because the spherical crown of valve seat and spool is all metal, long-time use can cause wearing and tearing, when wear extent arrives to a certain degree, under valve rated working pressure, can cause valve seal to reveal, valve control was lost efficacy, in the serious working life that shortens valve, even cause local pipe control malfunctioning, and valve is scrapped, cause user cost to improve, and the safety of whole pipe-line system is threatened.In addition, valve seat is fixed on valve body by trim ring, and the sealing between valve seat and valve body relies on trim ring completely.When seepage appears in valve seat and valve body, need to regulate the compression degree of trim ring, regulate difficulty larger, waste time and energy.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of eccentric valve, comprise valve body, spool, lower shaft, valve rod, valve seat and trim ring, spool is positioned at valve body, and its upper end is connected with valve rod, and lower end is connected with valve body by lower shaft, the spherical crown of spool and valve seat laminating, valve seat is fixed on valve body by trim ring, it is characterized in that being respectively equipped with wearing layer on described spool and described valve seat opposite flank, and described trim ring is made up of two or more trim ring sheets.
The material of described wearing layer is stainless steel.
The quantity of described trim ring sheet is 4-8.
The beneficial effects of the utility model are: on spool and valve seat opposite flank, wearing layer is set, and adopts stainless steel, can prevent the wearing and tearing of spool and the contact surface of valve seat, make the good sealing of the long-term maintenance of the utility model, improve working life.Trim ring is made up of multiple trim ring sheets, and each trim ring sheet can regulate separately, has ensured that it can well be fixed on valve seat on valve body, improves the sealability between valve seat and valve body.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is ring pressing construction schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
In figure, 1, valve body; 2, spool; 3, lower shaft; 4, valve rod; 5, valve seat; 6, trim ring; 7, wearing layer.
As shown in Figure 1 and Figure 2, spool 2 is positioned at valve body 1, its upper end is connected with valve rod 4, lower end is connected with valve body 1 by lower shaft 3, the spherical crown of spool 2 and valve seat 5 are fitted, and valve seat 5 is fixed on valve body 1 by trim ring 6, on spool 2 and valve seat 5 opposite flanks, are respectively equipped with wearing layer 7, the material of wearing layer 7 is stainless steel, and trim ring 6 is made up of six trim ring sheets.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
