Abstract
Dress formula inclined-plane ultralow temperature Float ball valve in one.Mainly solve present upper dress formula inclined-plane ultralow temperature Float ball valve spheroid is stressed press down time, can drive that two valve components in left and right are asymmetric to be pressed down, thus cause valve seat insert unbalance stress even to damage valve seat insert, cause the problem of leakage.It is characterized in that: described valve rod (4) outside is also arranged with spring bearer plate (6), and described spring bearer plate (6) one end compresses with spring (5) and coordinates, and the other end both sides compress with described valve component (11) respectively and coordinate.The utility model provides a kind of upper dress formula inclined-plane ultralow temperature Float ball valve; spring force drives two downward wedgings of valve component by spring bearer plate; also drive the spheroid be wrapped among valve component to move downward simultaneously; to valve seat insert wedging; doing so avoids two asymmetric motions of valve seat; thus protecting valve seat insert, Leakage prevention, Safety performance is good.
Description
Technical field
The utility model belongs to ball valve field, particularly dress formula inclined-plane ultralow temperature Float ball valve in one.
Background technique
Present upper dress formula inclined-plane ultralow temperature Float ball valve is provided with spring between valve rod and spheroid, spring force acts directly on spheroid, then the power on spheroid is relied on to drive valve seat insert, valve seat insert drives whole valve seat to move downward wedging again, this will cause spheroid and valve seat to produce assymmetric motion, in other words spheroid has moved downward, and two, left and right valve component not necessarily can move downward simultaneously, the sealing surface unbalance stress of the valve seat insert in ball seal face and valve component will be caused, in switch is crossed into, the ball mouth at spheroid two ends can be bad to stinging valve seat insert, valve is produced leak.
Model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of upper dress formula inclined-plane ultralow temperature Float ball valve, mainly solve present upper dress formula inclined-plane ultralow temperature Float ball valve spheroid is stressed press down time, can drive that two valve components in left and right are asymmetric to be pressed down, thus cause valve seat insert unbalance stress even to damage valve seat insert, cause the problem of leakage.
The technological scheme that the utility model adopts is:
Dress formula inclined-plane ultralow temperature Float ball valve in one, comprise valve body, valve gap, spheroid and valve rod, described valve body is connected with valve gap, described stem bottom is connected with described spheroid, be arranged with spring outside described valve rod, on described valve body, both sides all tilt to be provided with the valve component corresponding with spheroid, are also arranged with spring bearer plate outside described valve rod, described spring bearer plate one end compresses with spring and coordinates, and the other end both sides compress with described valve component respectively and coordinate.
Be provided with spring pressure ring bottom described spring bearer plate, described spring pressure ring compresses with described valve component and coordinates.
Also be provided with limited ring bottom described spring bearer plate, described limited ring to be located at inside spring pressure ring and corresponding with spring pressure ring.
Described valve body is structure as a whole.
Also comprise spacer, described spacer two ends compress with valve gap and spring respectively and coordinate.
The beneficial effects of the utility model are: the utility model provides a kind of upper dress formula inclined-plane ultralow temperature Float ball valve; spring force drives two downward wedgings of valve component by spring bearer plate; also drive the spheroid be wrapped among valve component to move downward simultaneously; to valve seat insert wedging; doing so avoids two asymmetric motions of valve seat; thus protecting valve seat insert, Leakage prevention, Safety performance is good.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model embodiment.
Fig. 2 is Figure 1A place enlarged view of the utility model embodiment.
In figure, valve body 1, valve gap 2, spheroid 3, valve rod 4, spring 5, valve component 11, pressing plate 6, spring pressure ring 61, limited ring 62, spacer 12.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail: as shown in Figure 1 with Figure 2, dress formula inclined-plane ultralow temperature Float ball valve in one, comprise valve body 1, valve gap 2, spheroid 3 and valve rod 4, described valve body 1 is connected with valve gap 2, be connected with described spheroid 3 bottom described valve rod 4, spring 5 is arranged with outside described valve rod 4, described spring 5 two ends compress with valve gap 2 and spring bearer plate 6 respectively, described spring bearer plate 6 one end compresses with spring 5 and coordinates, and the other end both sides compress with described valve component 11 respectively and coordinate.By the valve of said structure design, finally power is delivered on two valve components 11.Valve component comprises metal o-ring, valve seat insert, bracing ring prior art, repeats no more.Spring band move spring bearer plate press down time, the spring pressure ring be provided with by valve component top drives valve component to press down, and then drive the spheroid be wrapped between valve component to press down downwards simultaneously simultaneously, avoid two valve component assymmetric motions, use safer.The utility model provides a kind of upper dress formula inclined-plane ultralow temperature Float ball valve, at valve component with when moving downward, packs tightly the downward wedging of spheroid simultaneously; doing so avoids two asymmetric motions of valve component; thus protecting valve seat insert, Leakage prevention, Safety performance is good.
In the utility model, as shown in the figure, be provided with spring pressure ring 61 bottom described spring bearer plate 6, described spring pressure ring 61 compresses with described valve component 11 and coordinates.Processing is simple, and using effect is good.
In the utility model, as shown in the figure, be also provided with limited ring 62 bottom described spring bearer plate 6, described limited ring 62 to be located at inside spring pressure ring 61 and corresponding with spring pressure ring 61., prevent spring pressure ring under pressure medium, departing from valve component, prevent spring pressure ring from positioning can not occur under pressure medium effect and come off, using effect is better, and structure is simple.
In the utility model, as shown in the figure, described valve body 1 is structure as a whole.Can sealing effect be ensured, use safer.
In the utility model, as shown in the figure, also comprise spacer 12, described spacer 12 two ends compress with valve gap 2 and spring 5 respectively and coordinate.Seal pressure pretension can be made reasonable, valve rod is provided with spacer and mends under ultralow-temperature operation conditions to the size and valve that adjust spring force and taste Sealing contraction, the size of spring force can be adjusted by modes such as spacer sizes.
Embodiment should not be considered as restriction of the present utility model, but any improvement done based on spirit of the present utility model, all should within protection domain of the present utility model.
