Abstract
The utility model provides a double-eccentric ceramic hemispherical valve which comprises a valve actuator mechanism, a connecting plate, a valve body, a valve base arranged in the valve body, a valve rod and a valve core driven by the valve rod; a ceramic material embedded belt A is arranged on the valve core; the ceramic material embedded belt A is arranged on the sealing position where the valve core and the valve base are mutually sealed; a ceramic material embedded belt B is arranged on the valve base; the ceramic material embedded belt B is arranged on the position where the valve base and the valve core are mutually sealed. The double-eccentric ceramic hemispherical valve has the advantages that the simple is simple; the added ceramic material embedded belts enable the design of the valve to become more scientific and reasonable; meanwhile, because the ceramic material has the characteristics of high-temperature resistance, flushing resistance and high toughness so that the structure of the valve core and the valve base which adopt the technology to be completer; meanwhile, the characteristics of high temperature resistance and flushing resistance of the valve are improved greatly; the service life of the valve is prolonged; particularly, the double-eccentric ceramic hemispherical valve is applicable to the worse working conditions.
Description
Technical field
The utility model relates to a kind of ball valve, specifically, has related to a kind of two eccentric ceramic semispherical valve.
Background technique
The ceramic semispherical valve of two off-centre is because of self superior characteristic, and it uses very extensive in the prior art; But spool and valve seat are in switch contact for a long time, and the two seals position and constantly weares and teares, and is of long duration, tight inadequately problem will occur sealing.
In order to overcome the above problems, people are seeking a kind of better solution always.
The model utility content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of structural design ingeniously, high temperature resistant, anti-is washed away, the two eccentric ceramic semispherical valve of good airproof performance thereby provide.
To achieve these goals, the utility model provides a kind of two eccentric ceramic semispherical valve, comprise valve actuator, land, valve body, be arranged on valve seat, valve rod in the valve body and the spool that drives by valve rod, described spool is provided with stupalith and inlays band A, described stupalith is inlayed band A and is arranged on described spool and seals the position mutually with described valve seat, described valve seat is provided with stupalith and inlays band B, and described stupalith is inlayed band B and is arranged on described valve seat and seals the position mutually with described spool.
The relative prior art of the utility model has substantive distinguishing features and progressive, specifically, compared with prior art structural change is little for the ceramic semispherical valve of this pair off-centre, the stupalith that increases is inlayed band makes valve design more scientific and reasonable, and, because of stupalith has high temperature resistant, anti-characteristics of washing away with high tenacity, the spool of feasible this technology of employing and the structure of valve seat are more perfect, simultaneously, make that this valve is high temperature resistant, abrasion resistance is greatly enhanced, and prolonged working life of valve, especially it is applicable to various comparatively abominable working conditions.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of spool described in the utility model;
Fig. 3 is the structural representation of valve seat described in the utility model.
Embodiment
Below by the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of two eccentric ceramic semispherical valve, comprise valve actuator 1, valve body 3, the land 2 that connects described valve actuator 1 and described valve body 3, be pressed on valve seat 6 in the valve body 3 by valve seat platen 9, the valve rod 4 that drives by described valve actuator 1, the spool 5 that drives by valve rod 4;
Wherein, be provided with a circle stupalith at described spool 5 outer side surfaces and inlay band A7, described stupalith is inlayed band A7 and is arranged on described spool 5 and seals the position mutually with described valve seat 6; Described valve seat 6 is provided with a circle stupalith and inlays band B8, and described stupalith is inlayed band B8 and is arranged on described valve seat 6 and seals the position mutually with described spool 5.
Under the working state, described stupalith is inlayed band A7 and described stupalith and is inlayed band B8 and be in contact with one another and make ball valve to be sealed.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characteristics is equal to replacement embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technological scheme scope that the utility model asks for protection.
Claims (1)
1, a kind of two eccentric ceramic semispherical valve, comprise valve actuator, land, valve body, be arranged on valve seat, valve rod in the valve body and the spool that drives by valve rod, it is characterized in that: described spool is provided with stupalith and inlays band A, described stupalith is inlayed band A and is arranged on described spool and seals the position mutually with described valve seat, described valve seat is provided with stupalith and inlays band B, and described stupalith is inlayed band B and is arranged on described valve seat and seals the position mutually with described spool.
