Description
Technical field
The utility model relates to a kind of valve, and what be specifically related to is the compensation valve sealing structure of pad.
Background technique
The vacuum valve kind of using on vacuum pipe is more, but which kind of valve no matter, if sealed, bad seepage will occur.Thereby, in order to solve sealing problem, conventionally adopt following two kinds of modes:
One, assembling firmly; This mode is to assemble according to actual accessory, although lower by this assembling mode cost, length dimension can not guarantee, and then greatly affect closure size.If but accurate control size, the cost dropping into will be higher, and its sealing effect is also not ideal.
Two, utilize spring-compensating; In assembly process, the dynamics needing is larger, is not easy assembling.And when the power that acts on valve gap when manifold pressure approaches pressing force of the spring, can not effective sealing, greatly affect sealing effect.
Model utility content
The purpose of this utility model is to solve that existing vacuum valve sealability is bad, inconvenient problem is safeguarded in dismounting, provide a kind of with low cost, seal the compensation valve sealing structure of pad reliable, simple to operate.
For solving above-mentioned shortcoming, the technical solution of the utility model is as follows:
The compensation valve sealing structure of pad, mainly by valve body, the outer sleeve of bottom and valve body welding, lower flange with the welding of outer sleeve top, be arranged in outer sleeve and the valve gap being connected with valve body by sealed bottom pad, the inner sleeve that bottom is connected with valve gap, be positioned at the valve rod that inner sleeve and bottom are connected with valve gap, the upper bush that is arranged on inner sleeve top and is connected with inner sleeve by more than one compensate gasket, be positioned at the upper flange of lower flange top, and the O type circle between upper flange and lower flange forms.
Preferably, the thickness of described compensate gasket is 0.1～5mm, and quantity is 1～20.
The height difference of described lower flange and upper flange is 0.2～0.5mm.
In order to reach sealing effect better, on described lower flange, be provided with tapped hole, described upper flange is bolted on the tapped hole of lower flange.
Further, described valve rod bottom is threaded with valve gap.
The utility model compared with prior art, has the following advantages and beneficial effect:
1, the utility model is poor according to the actual height forming between lower flange and inner sleeve after assembling, can compensate by combination seal pad being set between lower flange and inner sleeve or certain thickness single sealing gasket being set, and operates very simple; After above-mentioned compensation, can effectively regulate fitted position, and the valve seal reliable performance of assembling out, cheap for manufacturing cost.
2, the O type circle arranging between lower flange and upper flange in the utility model, after it matches with sealing gasket, effectively avoids the not good problem of single sealing gasket sealing effect, further strengthens sealing effect of the present utility model.
3, in the utility model, valve gap is connected with threaded stem, and the set-up mode of the inner sleeve press seal of valve gap while extremely having facilitated maintenance proposes valve gap and spool, makes housekeeping operation easier.
Accompanying drawing explanation
Fig. 1 is external structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of A-A section in Fig. 1.
Fig. 3 is the structure for amplifying schematic diagram at B place in Fig. 2.
Wherein, the component name that in figure, reference character is corresponding is called:
1-valve body, 2-outer sleeve, 3-lower flange, 4-sealed bottom pad, 5-valve gap, 6-inner sleeve, 7-valve rod, 8-compensate gasket, 9-upper bush, 10-upper flange, 11-O type circle, 12-bolt.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof, the utility model is described in further detail, but mode of execution of the present utility model is not limited to this.
Embodiment
The compensation valve sealing structure of pad, is mainly comprised of valve body 1, valve gap 5, outer sleeve 2, inner sleeve 6, valve rod 7, upper bush 9, upper flange 10 and lower flange 3, and the annexation between its each parts is as follows:
As depicted in figs. 1 and 2, inner sleeve 6 and valve gap 5 are all positioned at outer sleeve 2 inside, and inner sleeve 6 is positioned at valve gap 5 tops, and the bottom of inner sleeve 6 is connected with valve gap 5.7 of valve rods are positioned at inner sleeve 6 inside, and its bottom is threaded with valve gap 5.
Described outer sleeve 2 bottoms and valve body 1 welding, weld with lower flange 3 on the top of this outer sleeve 2, is provided with upper flange 10 on lower flange 3.On lower flange 3, be provided with tapped hole, 10 of this upper flanges are fixedly connected with the tapped hole on lower flange 3 by bolt 12.
Under the condition being welded to connect at lower flange 3, outer sleeve 2, valve body 1, need to accurately control between guarantee valve gap 5 and valve body 1 fitted position of inner sleeve 6, valve gap 5, valve body 1, and the press seal between upper flange 10 and lower flange 3.
If but to control respectively the fitted position of inner sleeve 6, valve gap 5, outer sleeve 2, valve body 1, manufacture cost can significantly increase, and still can have tolerance range in fitted position.Thereby the utility model, in order to overcome the problems referred to above, reaches best sealing effect, its technological scheme adopting is as follows:
As shown in Figures 2 and 3, O type circle 11 is set between described lower flange 3 and upper flange 10, valve gap 5 is connected with valve body 1 by sealed bottom pad 4, and inner sleeve 6 tops are provided with by the connected upper bush 9 of more than one compensate gasket 8; The thickness of this compensate gasket 8 can be 0.1,0.2,0.5,1,2 or 5mm, and quantity is 1～20, as required choosing dress.
Owing to having height difference between lower flange 3 and inner sleeve 6 after assembling, thereby, thickness and the quantity of compensate gasket 8 can suitably be selected according to this height difference.By the selection of top seal pad 8 thickness and quantity, effectively realized the thickness compensation between lower flange 3 and inner sleeve 6, and then significantly improved sealing effect.After compensate gasket 8 and the equal installation of upper bush 9, the height difference on upper bush 9 tops and lower flange 3 between plane is 0.2～0.5mm, has effectively guaranteed the sealing of O type circle 11.
By above-mentioned setting, can effectively reach sealing effect best, and when reaching best sealing effect, greatly reduce manufacture cost.By the setting of said structure, maintenance assembling etc. are more convenient to operate, laborsaving, and sealability is more reliable.
According to above design, just can realize preferably the utility model.
