Abstract
The utility model discloses a valve, in particular to a semispherical valve with a dust-proof structure. The semispherical valve with the dust-proof structure comprises a valve body. A valve base and a valve core are arranged in the valve body, the upper portion of the valve core is connected with a valve shaft, an upper dust-proof sleeve is sleeved at the lower end of the valve shaft, and the upper dust-proof sleeve is located between the top of the valve core and the valve body. Due to the fact that the valve shaft is separated from fused slat in the valve body, the situation that a rotation pair is deadly blocked due to crystallizing of the fused salt is avoided.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of semispherical valve with dustproof construction.
Background technique
Existing have the characteristics such as open and close rapidly, compact structure, circulating resistance are little to pressing from both sides split type fused salt semi-spherical valve, and it played at the fused salt process system dam, the effect of throttling.But its deficiency is: 1. because in such valve operating mode reason valve, often need are by the fused salt of fusing point at 300 ℃, during normal operation, the operating temperature of valve is between 350-400 ℃, and fused salt is in a liquid state and flows in pipeline.In case and whole system is when needing parking maintenance, ducted temperature is near normal temperature, and makes fused salt be solid-state, thereby causes valve blockage.Due to such valve electric actuator mounting point from pipeline close to, the electric actuator ambient temperature is often greater than its normal working temperature, situation about crashing very easily occurs, thereby causes valve normally not open and close.3. revolute pair is (between valve shaft and valve body, between semiaxis and valve body) directly steep in fused salt liquid the inside, between valve shaft and valve body, easily enter fused salt between semiaxis and valve body, fused salt forms crystallization after cooling, frictional force when having increased the rotation of valve shaft and semiaxis, thereby the seize phenomenon often occurs, and then make valve stuck.
The model utility content
The utility model purpose is to provide a kind of semispherical valve with dustproof construction, and it keeps apart the fused salt in valve shaft and valve body for defects, thereby avoids the stuck situation of revolute pair that causes because of the fused salt crystallization.
The purpose of this utility model realizes by following structure, and it comprises: valve body, establish valve seat and spool in valve body, and spool top connects valve shaft, put dirt-proof boot outside the lower end of described valve shaft, and upper dirt-proof boot is between the top and valve body of spool.
Described spool bottom connects semiaxis.
Set dirt-proof boot outside the top of described semiaxis, lower dirt-proof boot is between the bottom and valve body of spool.
Described upper dirt-proof boot is identical with lower dust-proof cover structure, and upper dirt-proof boot and lower dirt-proof boot are cylindrical shape.
The upper end of described valve shaft connects electric actuator, the outside suit radiating sleeve of valve shaft, and radiating sleeve is connected between electric actuator and valve body.
Described valve body comprises valve endosome and lagging, establishes valve seat and spool in the valve endosome, and the outside suit of valve endosome lagging forms incubation cavity between lagging and valve endosome, is respectively equipped with import and outlet on lagging.
The utility model adopts and establishes dirt-proof boot in the lower end of valve shaft and set dirt-proof boot in the upper end of semiaxis, makes revolute pair directly not contact with transmission medium, has reduced the crystallization of transmission medium between revolute pair, and then has avoided the stuck phenomenon of spool.
Description of drawings
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is the amplification profile of dirt-proof boot on the utility model embodiment 1, and Fig. 3 is the amplification plan view of the utility model embodiment 1 dirt-proof boot.
Embodiment
The utility model embodiment 1 comprises as shown in Figure 1: valve body, valve body comprises valve endosome 2 and lagging 6, establish valve seat 1 and spool 3 in the valve endosome, the outside lagging 6 that connects of valve endosome 2, lagging 6 is enclosed within outside valve endosome 2,2 of lagging 6 and valve endosomes form incubation cavity 12, be respectively equipped with import 10 and outlet 11 on lagging 6, spool 3 tops connect valve shaft 8, spool 3 bottoms connect semiaxis 4, are connected with valve seat 1 in valve body endosome 2, and valve seat 1 directly is connected in valve body endosome 2, it does not need external flange again, greatly reduces the leak-down rate of valve.The upper end of valve shaft 8 connects electric actuator 9, the outside suit radiating sleeve 7 of valve shaft 8, and radiating sleeve 7 is connected between electric actuator and valve body, and radiating sleeve has increased the heat diffusion area of valve shaft part, thereby effectively reduces the operating temperature of electric actuator.Import 10 is used for connecting steam or hot water pipe, outlet 11 is used for the discharges with recycle gas or liquid, by passing into hot steam or hot water in incubation cavity 12, thereby has avoided system when parking maintenance, fused salt solidifies the obstruction valve, makes the fused salt in valve remain liquid condition.Electric actuator 9 drives valve shaft 8 rotations, and is with simultaneously movable valve plug 3 do clockwise or rotate counterclockwise in valve shaft 8 rotations, can realize closing or Open valve.
As dirt-proof boot 5 on the lower end peripheral hardware of Fig. 1, Fig. 2 and valve shaft shown in Figure 3, and upper dirt-proof boot is between the top and valve body 2 of spool 3, spool 3 bottoms connect semiaxis 4, set dirt-proof boot 13 outside the top of semiaxis, lower dirt-proof boot 13 is between spool 3 bottoms and valve body 4, upper dirt-proof boot 5 is identical with the structure of lower dirt-proof boot 13, and upper dirt-proof boot 5 and lower dirt-proof boot 13 are cylindrical shape, and lower dirt-proof boot 13 diameters are greater than the diameter of upper dirt-proof boot 5.Upper and lower dirt-proof boot make the fused salt in valve body can't be by gap between valve shaft and semiaxis and valve body to valve shaft top or the semiaxis bottom flow, thereby avoided causing valve shaft and valve body because of the fused salt crystallisation by cooling, stop up and the seize phenomenon of generation between semiaxis and valve body, improved the working efficiency of valve.
Embodiment 2 comprises: valve body, establish spool and valve seat in valve body, and spool top connection valve shaft, the upper end of valve shaft connects manual actuator.Dirt-proof boot on the lower end peripheral hardware of valve shaft, and upper dirt-proof boot is between the top and valve body of spool, upper dirt-proof boot is cylindrical shape, upper dirt-proof boot is that the fused salt in valve pocket can't flow to valve shaft top by the gap between valve shaft and valve body, thereby has avoided causing because of the fused salt crystallisation by cooling seize phenomenon that between valve shaft and valve body, obstruction occurs.The rotation of valve shaft is with movable valve plug do clockwise or rotate counterclockwise simultaneously, can realize closing or Open valve.
Structure of the present utility model also can be used the valve of other kinds conveying fused salt, as: fused salt ball valve or fused salt stopcock.
