Abstract
A kind of antibiotic stop valve.Mainly solve between the valve rod of existing antibiotic stop valve and annular locking plate easily loosening, thereby cause sealing problem not in place.It is characterized in that: described valve rod and annular locking plate are integral type structure.Its advantage is that not only structure is simpler, and there will not be the situation of rocking between valve rod and annular locking plate, and sealing effect is better.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of antibiotic stop valve.
Background technique
The open-shut device of antibiotic stop valve is the flap of stopper, sealing is plane or the conical surface above, flap, along the center line moving linearly of valve seat, can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
Because valve rod unlatching or the shutoff stroke of such valve are relatively short, and there is cutting function very reliably, due to the variation of valve seat port and the stroke of flap relation in direct ratio, be very suitable for the adjusting to flow again.Therefore, such valve is suitable as cut-out or adjusting and throttling use very much.
At present, valve rod one end of antibiotic stop valve is by an annular locking plate and flap axial limiting, and valve rod, annular locking plate, flap are split-type structural each other, and unlatching or throttle down can make the matching loose between valve rod and annular locking plate, thereby valve rod easily rocks, cause sealing not in place.
Model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of antibiotic stop valve, solve between the valve rod of existing antibiotic stop valve and annular locking plate easily loosening, thereby cause sealing problem not in place.
The technological scheme that the utility model adopts: a kind of antibiotic stop valve, comprise valve body, valve rod, flap and valve gap, described valve body is fixedly connected with valve gap, flap is positioned at valve body, valve rod one end penetrates valve body and is fixedly connected with flap, between described valve rod and flap, by annular locking plate, locate, described valve rod and annular locking plate are integral type structure.
Described annular locking plate peripheral hardware has one deck wearing layer.
Described wearing layer is cemented carbide.
Described stem bottom is provided with positioning boss, and described flap is provided with the positioning groove corresponding with positioning boss.
The beneficial effects of the utility model are: adopt above scheme, described valve rod and annular locking plate are integral type structure, and not only structure is simpler, and there will not be the situation of rocking between valve rod and annular locking plate, and sealing effect is better.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
Fig. 2 is the enlarged diagram at A place in Fig. 1.
1-valve body in figure, 2-valve gap, 3-valve rod, 4-flap, 5-flap nut, 6-annular locking plate, 7-wearing layer, 8-positioning boss, 9-positioning groove.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further: as shown in Figures 1 and 2, a kind of antibiotic stop valve, comprise valve body 1, valve rod 3, flap 4 and valve gap 2, described valve body 1 is fixedly connected with valve gap 2, flap 4 is positioned at valve body 1, valve rod 3 one end penetrate valve body 1 and are fixedly connected with flap 4
Described valve rod 3 is integral type structure with annular locking plate 6, and fixing spacing, not only simple in structure, easy for installation by flap nut 5 and flap 4, and the situation that there will not be valve rod 3 to rock, and sealing effect is better.
Described annular locking plate 6 is outer is provided with one deck hard alloy abrasion-resistant layer 7, and the wearing and tearing when further reducing annular locking plate 6 at valve opening or closing, make its longer service life.
Described valve rod 3 bottoms are provided with positioning boss 8, and described flap 4 is provided with the positioning groove corresponding with positioning boss 89, by positioning boss 8 and positioning groove 9, further valve rod 3 and flap 4 have been carried out spacingly, valve rod 3 can not rocked, better tightness.
