Abstract
The utility model provides a plate valve with a flow guide hole, wherein the valve plate uses two symmetrical flat valve plates, springs for making the two valve plates in open state along and close contact with the valve seat are distributed between the two valve plates, the number of the springs on the valve plates is at least two, the valve plates is arranged on the valve seat, the valve seat is fixed on the valve body, a locating structure is arranged between the two valve plates. Because the valve plates uses two symmetrical flat valve plates, springs for making the two valve plates in open state along and close contact with the valve seat are distributed between the two valve plates, the valve plate is in the top shutter and keeps the valve plates close contact with the valve seat under the push of the spring, thereby scraping off impurity on the surface of the shutter, cutting off the medium without leakage, and closing the valve. Because the bottom of the valve cap and the valve body are respectively installed with the discharge valve capable of flushing and discharging the impurity, the unused impurity is cleared, and the valve inner cavity is clean.
Description
One. technical field
This novel a kind of valve, particularly a kind of band pod apertures plate valve of relating to.
Two. background technique
The band pod apertures plate valve of prior art is seen Fig. 1, adopt to rotate handwheel 1` or adopts the electronic mode that waits other, makes nut 2` rotation drive that screw rod 3` does corresponding rotation and straight line moves, and moves up and down the effect that reaches switch valve thereby drive valve plate 7`.This valve valve plate 7` is the veneer overall structure, the centre has pod apertures, around the valve seat 6` spring 8` being housed makes sealing surface of seat and valve plate 7` keep in touch and seal, when having impurity in the medium, can be penetrated in the gap of valve seat 6` and valve body 5` as shown in Figure 2, Fig. 2 is Figure 1A portion enlarged view, because impurity makes valve seat stuck and can not make sealing surface of seat and valve plate keep in touch and seal, cause leakage and valve plate is surperficial owing to adhering to impurity, 4` is a valve gap.
Three summary of the invention
This novel purpose is: a kind of novel valve is provided, can prevents that when having impurity in the medium valve seat is stuck, thereby make sealing surface of seat and valve plate keep in touch and seal, and can prevent the leakage that causes because of valve plate surface attachment impurity.
The following structure of this novel employing realizes above-mentioned purpose: a kind of band pod apertures plate valve, comprise: handwheel, screw rod, nut, valve gap, valve body, valve seat, its valve plate adopts the valve plate of two symmetrical flat shape structures, be distributed with the spring that can make two valve plates keep open configuration and closely contact all the time between two valve plates with valve seat, the number of springs that distributes on the valve plate is at least more than two, valve plate is as on the valve seat, and valve seat is fixed on the valve body.
Be provided with position structure between two valve plates.
Position structure between two valve plates is to prevent the positioning ring that misplaces, and positioning ring places in the locating slot.
The escape cock that can wash with discharge impurities is equipped with in the valve body bottom.
The escape cock that can wash with discharge impurities is housed on the valve gap.
Two valve plate adjacent surfaces are provided with the groove of placing spring, and spring places in the groove.
Adopt said structure when rotating handwheel or the electronic mode that waits other, when making the nut rotation drive screw rod to do corresponding rotation and straight line and move, move up and down the effect that reaches switch valve thereby drive gate valve.Because valve plate adopted the valve plate of two symmetrical flat shape structures during this was novel, be distributed with the spring that can make two valve plates keep open configuration and closely contact all the time between two valve plates with valve seat, when going downwards to its pod apertures of bottom, valve plate overlaps MEDIA FLOW mistake, valve open with through hole on the valve seat.When valve plate keeps valve plate closely to contact with valve seat to the promotion of top flashboard at spring, thereby can guarantee to scrape off the lip-deep impurity of flashboard, block medium and do not leak, valve reaches the purpose of closing.
Because valve gap and valve body bottom are equipped with the escape cock that can wash with discharge impurities respectively, can remove the impurity of accumulation, guarantee the cleaning of valve cavity.

Five specific implementations
As shown in the figure, a kind of band pod apertures plate valve, comprise: handwheel 1, screw rod 3, nut 2, valve gap 4, valve body 5, valve seat 6, its valve plate 7 adopts the valve plate of two symmetrical flat shape structures, be distributed with the spring 9 that can make two valve plates 7 keep open configuration and closely contact all the time between two valve plates 7 with valve seat 6, spring 9 quantity that distribute on the valve plate 7 are at least more than two, and valve plate 7 is as on the valve seat 6, and valve seat 6 is fixed on the valve body 5.
Be provided with position structure between two valve plates 7.
Position structure between two valve plates 7 is to prevent the positioning ring 10 that misplaces, and positioning ring places in the locating slot 13.
The discharging 8 that can wash with discharge impurities is equipped with in the bottom of valve body 5.
The escape cock 8 that can wash with discharge impurities is housed on the valve gap 4.
Two valve plates, 7 adjacent surfaces are provided with the groove 11 of placing spring 9, and spring 9 places in the groove 11.Employing rotation handwheel 1 or the electronic mode that waits other make nut 2 rotation drive screw rods 3 do corresponding rotation and straight line moves, and move up and down the effect that reaches switch valve thereby drive valve plate 7.Overlap the MEDIA FLOW mistake when valve plate 7 goes downwards to its pod apertures 12 of bottom with through hole 51 on the valve seat 5, valve open as shown in Figure 3 at this moment.Valve plate 7 is kept closely contacting with valve seat 6 under the promotion of spring 9 when valve plate 7 goes upward to the top valve plate, as Fig. 4, shown in Figure 5, valve reaches the purpose of closing.
The valve gap 4 on the valve and the bottom of valve body 5 are equipped with the escape cock 8 that can wash with discharge impurities respectively, to remove the impurity of accumulation, guarantee the cleaning of valve cavity.
Valve plate 7 is as Fig. 7 and shown in Figure 6, be made of a pair of symmetrical two valve plates, positioning ring 10 is positioned at the locating slot 13 of two valve plates, is distributed with a plurality of springs 9 between two valve plates 7, and spring 9 places groove 11, and positioning ring 10 guarantees that two valve plates 7 do not misplace.The top of valve plate 7 has the pod apertures 12 of a circle to be used to pass through medium.Because spring 9 is distributed in the diverse location of two valve plates, two valve plates can remain under the thrust of spring 9 and open and keep tight contact condition with valve seat.
