Background technique
Have the structural representation of stop valve as shown in Figure 1 now, it comprises hand wheel nut 1 ', handwheel 2 ', copper nut 3 ', gland support 4 ', stem packing 5 ', stud bolt 6 ', nut 7 ', spring 8 ', valve gap 9 ', sealing gasket 10 ', valve rod 11 ', combined moving spool 12 ', valve body 13 ', valve seat 14 ' and Gland 15 ', valve gap 9 ' is passed in the valve rod 11 ' upper end of this stop valve, stem packing 5 ', Gland 15 ', copper nut 3 ' and handwheel 2 ' back are screwed onto with hand wheel nut 1 ', copper nut 3 ' is fixed in the through hole on gland support 4 ' top, gland support 4 ' bottom upper surface is screwed onto by regulating bolt with Gland 15 ', stem packing 5 ' is arranged at valve gap 9 ' inner chamber, valve gap 9 ' upper surface and gland support 4 ' lower surface are fixed, valve gap 9 ' is spirally connected fixing below by stud bolt 6 ' and nut 7 ' with valve body 13 ', stud bolt 6 ', be provided with spring 8 ' between nut 7 ' and the valve gap 9 ', be provided with sealing gasket 10 ' between valve gap 9 ' and the valve body 13 ' junction surface, valve body 13 ' epicoele 133 ' bottom is welded with valve seat 14 ', the water intake 131 ' in valve seat 14 ' hollow cavity lower end and valve body 13 ' left side connects, the water outlet 132 ' and the valve body 13 ' epicoele on valve body 13 ' right side connect, valve rod lower end 11 ' is connected and fixed with the groove on combined moving spool 12 ' top, this stop valve drives combined moving spool straight line motion about in the of 12 ' by valve rod 11 ', make and separate or combination between combined moving spool 12 ' and the valve seat 14 ', thereby realize valve open or close, the spool of combined moving shown in the figure 12 ' is sealed in the cavity top of valve seat 14 ', be the valve closing state, combined moving spool 12 ' lower surface is against valve seat 14 ' upper surface.
The shortcoming of this kind stop valve is that valve seat 14 ' bottom is welded in valve body 13 ' lower end, because valve seat 14 ' and combined moving spool 12 ' Long contact time, be easy to wearing and tearing each other, be difficult for repairing, valve seat in a single day can not be with must related valve body 13 ' integral body scrapping, waste so very much resource, so the working life of this stop valve is short.
The model utility content
The purpose of this utility model is to provide a kind of quick service type throttling stop valve, and it is repaired and long service life easily.
To achieve these goals, technical solution of the present utility model is: a kind of quick service type throttling stop valve, it comprises valve gap, first sealing gasket, valve rod, the combined moving spool, valve body and valve seat, valve gap and valve body are spirally connected fixing, be provided with first sealing gasket between valve gap and the valve body, valve body epicoele bottom is provided with valve seat, valve rod lower end and combined moving spool upper grooves are connected and fixed, combined moving spool lower surface is against the valve seat upper surface, be provided with second sealing gasket between wherein said valve body epicoele bottom and the valve seat, inner cavity surface is equipped with actor playing a supporting role pipe on the valve body between the described valve seat upper surface and first sealing gasket.
The utility model quick service type throttling stop valve, wherein said second sealing gasket is the belleville spring sealing gasket, its material selection INCONELX-750 high-temperature alloy steel.
The utility model quick service type throttling stop valve, the wherein said actor playing a supporting role manages and adopts the 25Cr2MoV material to make.
After adopting such scheme, the utility model quick service type throttling stop valve is provided with second sealing gasket between valve seat and valve body, inner cavity surface is provided with actor playing a supporting role's pipe on valve body, after wearing and tearing between valve body and the valve seat are scrapped, actor playing a supporting role's pipe, valve seat and second sealing gasket of this stop valve can be removed respectively, which has been gone bad is changed which, and convenient the repairing re-uses, valve body need not be thrown away, so it has increased the working life of this stop valve.
Description of drawings
Fig. 1 is the structural representation of existing stop valve;
Fig. 2 is the structural representation of the utility model quick service type throttling stop valve.
Embodiment
See also the structural representation of the utility model quick service type throttling stop valve shown in Figure 2, a kind of quick service type throttling stop valve, it comprises valve gap 1, first sealing gasket 2, valve rod 3, combined moving spool 4, valve body 5 and valve seat 6, valve gap 1 is spirally connected fixing with valve body 5, be provided with first sealing gasket 2 between valve gap 1 and the valve body 5, valve body 5 epicoeles bottom is provided with valve seat 6, be provided with second sealing gasket 7 between valve body 5 epicoeles bottom and the valve seat 6, it is the belleville spring sealing gasket, its material selection INCONELX-750 high-temperature alloy steel.Valve rod 3 lower ends and combined moving spool 4 upper grooves are connected and fixed, combined moving spool 4 lower surfaces are against valve seat 6 upper surfaces, inner cavity surface is equipped with an actor playing a supporting role and manages 8 on the valve body 5 between valve seat 6 upper surfaces and first sealing gasket 2, and this actor playing a supporting role manages 8 and adopts the 25Cr2MoV material to make.
The utility model quick service type throttling stop valve weares and teares bad time between valve seat 6 and combined moving spool 4, because valve seat 6 is to be movably installed in the valve body 5, it also is to be movably installed in the valve body 5 that the actor playing a supporting role on valve seat 6 tops manages 8, as long as unscrew the bolt between valve gap 1 and the valve body 5, combined moving spool 4 is taken out valve body 5 together with all parts one on its top, just the actor playing a supporting role in the valve body 5 can be managed 8 then, the valve seat 6 and second sealing gasket 7 are taken out from valve body 5 epicoeles respectively, because second sealing gasket 7 is the belleville spring sealing gasket, it has elasticity, therefore valve seat 6 is easy to take out in valve body 5, which parts has been broken is repaired which or directly more changes, very convenient laborsaving, and valve body 5 can also be used, so prolong the working life of this stop valve relatively.
The above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in related domain make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
