Abstract
The utility model discloses a kind of bellows single-seat adjusting valve of being convenient to maintenance, comprise valve body, valve seat, valve hole part and actuator, a plurality of bellowss are fixed on described valve hole part periphery by top board and base, between adjacent corrugations pipe, have spacer ring.Further, state the retaining ring that base comprises base plate, link and is fixed on valve hole part, described link and retaining ring have internal thread, and set screw nut withstands base plate after passing link and retaining ring.The bellows single-seat adjusting valve of being convenient to maintenance of the present utility model, bellows is removably fixed on valve hole part, changes bellows simple and convenient, and does not need the bellows of dismantling while taking out valve hole part.
Description
Technical field
The utility model relates to single-seat adjusting valve, specifically a kind of bellows single-seat adjusting valve of being convenient to maintenance.
Background technique
Direct single seat control valve is comprised of parts such as valve body, valve seat, spool, guide sleeve, valve gap, valve rod and fillers.Spool and valve rod link together.Connecting means can be fixed or the pin that is threaded is fixed with interference fit pin, also can valve rod and valve power station valve core integrated vehicle go out.Between valve gap and valve body, be provided with guide sleeve, for spool moves up and down, play the guiding role.Aperture on guide sleeve, connecting valve intracoelomic cavity and valve outlet port end.The medium of guide sleeve epicoele is easy to flow into valve outlet port end by aperture, can not affect the movement of spool.In the valve body of direct single seat control valve, only have a spool and a valve seat.Feature is that leakage rate is little, is easy to guarantee sealing.In structure, there are adjustment type and cut-off type.Their difference is that the shape of spool is different.
In prior art, bellows is fixed on valve hole part, and dismounting and change bellows is very inconvenient, is easily damaged to valve hole part, if take out valve hole part, the bellows of first dismantling.
Model utility content
In order to solve the above-mentioned technical problem existing in prior art, the utility model provides a kind of bellows single-seat adjusting valve of being convenient to maintenance, comprise valve body, valve seat, valve hole part and actuator, a plurality of bellowss are fixed on described valve hole part periphery by top board and base, between adjacent corrugations pipe, have spacer ring.
Further, state the retaining ring that base comprises base plate, link and is fixed on valve hole part, described link and retaining ring have internal thread, and set screw nut withstands base plate after passing link and retaining ring.
The bellows single-seat adjusting valve of being convenient to maintenance of the present utility model, bellows is removably fixed on valve hole part, changes bellows simple and convenient, and does not need the bellows of dismantling while taking out valve hole part.
Accompanying drawing explanation
Fig. 1 is the structural representation of being convenient to the bellows single-seat adjusting valve of maintenance of the present utility model;
Fig. 2 is the partial enlarged drawing of bellows assembly.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the bellows single-seat adjusting valve of being convenient to maintenance of the present utility model, comprise valve body 1, valve seat 2, valve hole part 3 and actuator 4, a plurality of bellowss 5 are fixed on valve hole part 3 peripheries by top board 6 and base 7, have spacer ring 8 between adjacent corrugations pipe 5.
As shown in Figure 2, described base 7 comprises base plate 9, link 10 and is fixed on the retaining ring 11 of valve hole part 3, link 10 and retaining ring 11 have internal thread, withstand base plate 9, for bellows 5 is fixed after set screw nut 12 passes link 10 and retaining ring 11.
The bellows single-seat adjusting valve of being convenient to maintenance of the present utility model, only need unclamp set screw nut replaceable while changing bellows.
