Abstract
The utility model provides a high temperature steam regulating valve including a valve body and a sleeve arranged on the valve body, a valve plug slidingly cooperated with the sleeve adjusts the flow quantity of the valve through the up-down movement of the valve rod. The regulating valve is characterized in that a plurality of holes are arranged in the periphery of the sleeve and the lower end of the sleeve is provided with a turbulent flow cover, and a plurality of small holes are arranged in the turbulent flow cover, and the small holes are communicated with the outlet of the valve body. The regulating valve disperses and changes the flowing state of the steam medium in the value body by arranging the plurality of small holes in the sleeve and the turbulent flow cover, thereby reducing or preventing vibration, and reducing noise.
Description
Technical field
The utility model belongs to a kind of valve body, says especially to relate to a kind of high temperature that is applicable to High Pressure Difference, low noise, low vibrations, the modulating valve of steam medium special occasions.
Background technique
In the industrial automation liquid control system, modulating valve is one of fluid control devices of being used widely, and is used for switching on or off medium.When flow overregulates the valve throttle orifice, owing to choke area sharply changes, constriction in flow area, flow velocity raises, and pressure drop easily produces to block and flows, and produces cavitation, and these situations all are the main causes of bringing out noise.When pressure reduction was little before and after the valve, the noise of restriction was very little, selected conventional modulating valve to meet the demands.But when pressure reduction is higher before and after the restriction, if still select conventional modulating valve then can produce great noise, very easily producing the phenomenons such as cavitation erosion, seriously is to cause equipment accident.Can avoid the generation of above-mentioned phenomenon by the inner parts structure of rational design modulating valve.
Therefore, the problem that exists in using for above modulating valve is necessary this modulating valve is improved, and overcomes deficiency in original regulating valve structure with this.
The model utility content
The purpose of this utility model just provides a kind of high-temperature steam governing valve, solves the problem that the noise that original modulating valve exists is large, vibration is severe and produce the phenomenons such as cavitation erosion.
A kind of high-temperature steam governing valve of the present utility model, comprise valve body and be installed in the interior sleeve of valve body, the valve plug that is slidingly matched with sleeve is by the size that moves up and down the flow that regulating valve opens of valve rod, it is characterized in that: around described sleeve, be provided with a lot of holes and be installed with turbulent flow in the lower end of sleeve and cover, offer a lot of apertures on the described turbulent flow cover, the turbulent flow cover communicates with valve outlet.By offering a lot of apertures at sleeve and turbulent flow cover, can make fluid pass through sleeve wall aperture all around and flow into sleeve, compile again rear flow direction turbulent flow cover, and on the turbulent flow cover many apertures being arranged also, the more even more stratified outflow valve body of fluid disperses by making runner, it can make surface friction drag increase, Flow Field Distribution is even, does not produce large eddy-currents, thereby has reduced noise.
Further, the support of described valve rod and fixed valve body actuator is provided with half nuts, is provided with groove on the described half nuts, and described groove matches with boss on the support.Match with boss on the support by the groove that arranges on the half nuts, prevented that valve rod is with ovable valve stem and produces together rotation along with sleeve under the active force of fluid.
Further, be provided with holding down bolt between the bonnet on the described valve body and the support.Arrange like this and just can fix the parts that will be fixed on the support and limited, can be along with rotation.
Further, be provided with sink on the described bonnet, described sink is exactly radiating fin even and that be parallel to each other.Radiating fin can make biography fully be diffused in the air to the heat on the bonnet, does not have more heat and passes to control system.
Further, the described filler that also is provided with between bonnet and valve rod is provided with heat-proof device below filler.Increase rare can the biography to control mechanism of heat that this heat-proof device guarantees medium more, guarantee the normal operation circumstances of control mechanism.
Beneficial effect
The beneficial effects of the utility model are by at sleeve and turbulent flow cover a lot of apertures being set, and disperse and change the flowing state of steam medium in valve, reduce or have avoided vibration; Reduce noise and vibration.

Embodiment
Such as Fig. 1, Fig. 2, shown in be a kind of high-temperature steam governing valve, comprise valve body 1, have the valve body import and export, and be arranged on the sleeve 3 on the valve body, the valve plug 4 that can in sleeve 3, move up and down, valve plug 4 is fixed on the valve rod 5, what match with valve rod 5 is the bonnet 6 that is attached to outside the valve rod 5, and bonnet 6 upper ends fixedly are equiped with the support 10 of control system, have bolt 7 that bonnet 6 is fixed on the support 10 on the support 10.The upper end that cooperates with valve rod 5 at valve gap 6 also is provided with filler 8, is used for sealing.Half nuts 9 connects together the push rod 11 of valve rod 5 and actuator 12, is used for valve rod 5 is operated control; As shown in Figure 3, valve rod upper end is provided with half nuts 9 with the support of fixed valve body control system, is provided with groove on the described half nuts, and described groove matches with boss on the support 10.
Such as Fig. 1, Fig. 4, shown in Figure 5, be provided with a lot of apertures not of uniform size around the sleeve 3, valve plug is by moving up and down to control the quantity of aperture, thereby control media flow, be provided with turbulent flow cover 2 in sleeve 3 lower ends, described turbulent flow cover 2 also offers many apertures, communicates with the media outlet of valve body 1.As shown in Figure 3, valve rod and bonnet cooperatively interact, and are provided with bolt 7 between support 10 and the bonnet 6, guarantee that bonnet can not rotate, and therefore just support are fixed.
As shown in Figure 1, the described filler 8 that also is provided with between valve gap and valve rod is provided with the bonnet 6 with heat-proof device below filler.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
