Abstract
The utility model mainly adopts a ceramic valve seat and a ceramic valve core. The ceramic valve core is composed of a streamline throttling cone, a ceramic sealing ring, a soft sealing ring and an elastic rubber ring. The streamline throttling cone is used for regulating the area of a flow passage, achieving the purpose of regulating the flow. The valve core adopts soft and hard double sealing to improve the sealing performance, and zero leakage can be realized. The extension plane of the streamline throttling cone contains a valve core soft sealing surface, and the media flow in a sloping direction along the conical surface, which can avoid directly flushing the valve core sealing surface. Due to the adoption of the special ceramic sealing material, the service life of the valve can be prolonged numeral times.
Description
The utility model relates to a kind of ceramic throttling stop valve.
Existing throttle valve, kind is a lot, mainly is made of valve body, valve seat, valve gap, valve rod, spool and Sealing, because the middle brush of medium, spool, valve seat and Sealing etc. very easily wear and tear, and cause valve leak, make throttling valve breakdown and restriction effect bad, working life is short.
The purpose of this utility model is to overcome the defective that above-mentioned existing throttle valve exists, design a kind of seal reliably, anti-wash away, easily manufactured, the throttling that possesses pipeline fluid and turn-off bifunctional ceramic throttling stop valve.
Structural feature of the present utility model has reached above-mentioned purpose comprehensively.The utility model is a kind of ceramic throttling stop valve, comprise valve body, valve seat, valve gap, valve rod, handwheel, spool, guide mechanism and Sealing, it is characterized in that valve seat adopts ceramic material, the one installation shrinkage pool that adapts with valve seat is arranged on the valve body, one annular boss is arranged at the shrinkage pool bottom, valve seat is locked at by fastening piece on the boss of valve seat mounting hole, and a soft seal pad is arranged between valve seat and the valve body.
In order further to prolong the life-span of throttling stop valve, improve its throttling and turn-off effect, spool of the present utility model is made of streamlined throttling awl, valve core case, ceramic seal circle, soft seal circle and elastic rubber ring, two annular grooves are arranged on the valve core case, the ceramic seal circle is between throttling awl shoulder and valve core case, in the groove corresponding to the ceramic seal circle on the elastic caoutchouc circle embedding valve core case, the groove of corresponding ceramics seat on the valve core case, interference embeds the soft seal circle, and the plane of ceramic seal circle and streamlined throttling awl shoulder is higher than the sealing surface of soft seal circle.
In order to make the utility model throttling in use and to turn-off better effects if, body cavity of the present utility model has a guide mechanism corresponding to the spool lifting travel, and guide mechanism and valve core case are slidingly connected, and guide mechanism is threaded with valve gap.
The utility model is in when closing closed procedure; spool descends, and most fluid is at first turn-offed in the cylndrical surface of throttling awl, and then the ceramic seal face of spool contacts, is adjacent to valve seat; reach basic sealing; in this process, elastic rubber ring is compressed, in whole retraction core print seat grooves, the spool ceramic seal floats towards last; expose soft sealing face and contact, be adjacent to valve seat; reach sealing fully, therefore realized reducing the ceramic plane collision, the protection soft sealing face is avoided the purpose that medium washes away.
The utility model adopts ceramic valve seat, and intensity height, anti-washing away are simple in structure, easy to process; Adopt streamlined throttling awl, the extension conical surface of its throttling awl contains the spool soft sealing face, and medium can avoid directly washing away valve core sealed cover along conical surface obliquely flow; Adopt the special cermacis sealing material, make to prolong several times in working life of valve; Spool adopts soft, hard double seal, has improved sealability, can reach " zero leakage " sealing; When the utility model is in standard-sized sheet or Flow-rate adjustment state, rotation hand wheel, the actuate valve stem spiral lifting drives the spool vertical lift, and this structure had both been changed valve driving mechanism, had avoided the mutual friction of sealing surface phase again, had improved using effect.
In sum, because the utility model has adopted novel structure, utilize flexible barrier materials such as stupalith and rubber, teflon to realize soft, hard double seal, make that this throttling stop valve was both anti-to be washed away, the sealing effect that has high-quality again, reach zero leakage, simultaneously, its valve seat construction tube list, easily processing, therefore, the utlity model has throttling by effective, do not have leak, anti-ly wash away, outstanding advantage that the life-span is long, than common throttle valve and stop valve, its life-span can prolong several times, is a kind of novel throttling stop valve with promotional value.
